Live For Today (DJ Jerry feat. Missy Babe) Show me the road and I will find my own and you build the bridges and I"ll burn them down. So far away and all alone I roam I"m taking chances in the here and now. And all you wonder is who"s for sale but you won"t know now and I won"t tell. You"re always hiding, throwing up your hands while heroes ride again. God only knows all the places I"ve been but I love this life that I"m live"n in and I won"t look back to regret yesterday. We"re not handed tomorrow so I"ll live for today. Another day and yet another"s done, spending the life living within the past. I"ll take the chance before the chance has gone. you never know when it will be your last But still you wonder who"s for sale you won"t know now and I won"t tell. You"re always hiding, throwing up your hands while heroes ride again. God only knows all the places I"ve been but I love this life that I"m live"n in. I won"t look back to regret yesterday. We"re not handed tomorrow so I"ll live for today. We"ll never know it When we run out of time until it"s all over with and there"ll be nowhere to run. We"ll never say it but we"re over our heads and we"re drowning inside all of these things we"ve said. God only knws all the places I"ve been but I love this life that I"m live"n in. I won"t look back to regret yesterday cuz we"re not handed tomorrow so I"ll live for today. God only knows all the places I"ve been but I love this life that I"m live"n in.

Environmental PollutionI read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular. Why? --Fresh air is getting less and less in Japan, and so is it in the U. S. A.In fact, environmental pollution is a very serious problem the whole world is facing.it is mainly caused by the waste products released from artificial substances, industrialproduction and increased consumption of goods. Bedsides, the use of chemical substancesin agriculture also causes environmental pollution. Look at the sky, you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us.How to change this condition? More and more countries are trying to work out some effective means to bring it under control, but no great success has been made.环境污染最近我读了一则消息说在日本，许多商人向顾客出售新鲜空气，现在这种情况越演越烈。为什么呢? 因为在日本新鲜空气越来越少，在美国也是如此。事实上，环境污染是整个世界正在面临的一个严重问题。这主要是由于人造物质，工业生产过程中所产生的废料以及消费商品的增长造成的。另外，在农业中使用化学物品也造成了环境污染。看看天空，你可以看到浓烟从高大的烟囱中释放出来，这些脏而有毒的物质流入我们赖以饮水的河流，数百万吨废物正堆积在我们周围。怎样改变这种状况呢？越来越多的国家正在试图拟定出一些有效措施控制环境污染，但至今成效不大。

We sometimes feel bad.Anyone happens to it more or later.But how to deal with bad feeling?What can we do to make us feel better? In my opinion ,we must have a brave heart to overcome difficulties.Firstly,we may have a sleep. Enough sleep is good for our feelings.Secondly we can pour out our heat to friends .Talk can eliminate worries. Thirdly, we can do some physical exercise.Exercise is important to your emotional well-being and improves the body"s ability to handle anxiety and stress. With confidence and sunshine, darkness will not come again.

How to Deal with the Exam StressEveryone may have the exam stress. A little bit of stress can be a good thing to us.If we have proper stress, we can think actively and work harder. Besides, it can remind us to review our lessons in time to remember them. So we can pass the exams easily.However, if we have too heavy stress, we can"t sleep well at night and we may feel too tired. We may fear the exams too much and fail in the end.In my opinion, to deal with stress, we"d better plan and prepare well. We should also form some good habits, such as enough exercise and healthy diets. Then we"ll feel relaxed and do well in the exams.如何处理考试压力每个人都会有考试的压力。一点点的压力可以让我们很好。如果我们有适当的压力，我们能积极思考和努力。此外，它可以提醒我们复习功课的时间来记住他们。所以我们可以很容易通过考试。然而，如果我们有太大压力，我们晚上都睡不好，我们会感觉很累。我们可能害怕最后太多不及格。在我看来，应对压力，我们做最好的计划和准备。我们也应该养成一些好的习惯，如足够的锻炼和健康饮食。然后我们会觉得轻松，在考试中取得好成绩。

后加doing,即mainly doing sth

原文： In Britain you"re allowed to drive a car when you"re seventeen.You have to get a special two-year driving license before you start.When you"re learning, someone with full license always has to be in the car with you. You don"t have to go to a driving school --a friend can teach you. The person with youisn"t allowed to take money for the lesson unless he"s got a teacher"s license. Before you"re allowed to have a full license, you have to take a driving test. You can take a test in your own car, but it has to be fit for the road. In the test, you have to drive round for half an hour and then answer a few questions. If you don"t pass the test, you"re allowed to take it again a few weeks laterif you want to. In 1970, a woman passed her fortieth test after 212 driving lessons! , When you"ve passed your test, you don"t have to take it again, and you"re allowed to go on driving as long as (只要) you like, if you"re healthy. Britain"s oldest driver was a man who drove in 1974 at the age of 100. Before 1904, everyone was allowed to drive, even children. Then from 1904 car drivers had to have a license. But they didn"t have to take a test until 1935. In the early days of car driving, before 1978, cars weren"t allowed to go faster than four miles an hour, and someone had to lead the car with a red flag.

Text Analysis is a major application field for machine learning algorithms. However the raw data, a sequence of symbols cannot be fed directly to the algorithms themselves as most of them expect numerical feature vectors with a fixed size rather than the raw text documents with variable length. 文本分析是机器学习算法的主要应用领域。 然而，原始数据，符号文字序列不能直接传递给算法，因为它们大多数要求具有固定长度的数字矩阵特征向量，而不是具有可变长度的原始文本文档。 In order to address this, scikit-learn provides utilities for the most common ways to extract numerical features from text content, namely: 为解决这个问题，scikit-learn提供了从文本内容中提取数字特征的最常见方法，即： In this scheme, features and samples are defined as follows: 在该方案中，特征和样本定义如下： A corpus of documents can thus be represented by a matrix with one row per document and one column per token (e.g. word) occurring in the corpus. 因此，文本的集合可被表示为矩阵形式，每行对应一条文本，每列对应每个文本中出现的词令牌(如单个词)。 We call vectorization the general process of turning a collection of text documents into numerical feature vectors. This specific strategy (tokenization, counting and normalization) is called the Bag of Words or “Bag of n-grams” representation. Documents are described by word occurrences while completely ignoring the relative position information of the words in the document. 我们称 向量化 是将文本文档集合转换为数字集合特征向量的普通方法。 这种特殊思想（令牌化，计数和归一化）被称为 Bag of Words 或 “Bag of n-grams” 模型。 文档由单词出现来描述，同时完全忽略文档中单词的相对位置信息。 As most documents will typically use a very small subset of the words used in the corpus, the resulting matrix will have many feature values that are zeros (typically more than 99% of them). 由于大多数文本文档通常只使用文本词向量全集中的一个小子集，所以得到的矩阵将具有许多特征值为零（通常大于99％）。 For instance a collection of 10,000 short text documents (such as emails) will use a vocabulary with a size in the order of 100,000 unique words in total while each document will use 100 to 1000 unique words individually. 例如，10,000 个短文本文档（如电子邮件）的集合将使用总共100,000个独特词的大小的词汇，而每个文档将单独使用100到1000个独特的单词。 In order to be able to store such a matrix in memory but also to speed up algebraic operations matrix / vector, implementations will typically use a sparse representation such as the implementations available in the scipy.sparse package. 为了能够将这样的矩阵存储在存储器中，并且还可以加速代数的矩阵/向量运算，实现通常将使用诸如 scipy.sparse 包中的稀疏实现。 CountVectorizer implements both tokenization and occurrence counting in a single class: 类 CountVectorizer 在单个类中实现了 tokenization （词语切分）和 occurrence counting （出现频数统计）: This model has many parameters, however the default values are quite reasonable (please see the reference documentation for the details): 这个模型有很多参数，但参数的默认初始值是相当合理的（请参阅 参考文档 了解详细信息）: Let"s use it to tokenize and count the word occurrences of a minimalistic corpus of text documents: 我们用它来对简约的文本语料库进行 tokenize（分词）和统计单词出现频数: The default configuration tokenizes the string by extracting words of at least 2 letters. The specific function that does this step can be requested explicitly: 默认配置通过提取至少 2 个字母的单词来对 string 进行分词。做这一步的函数可以显式地被调用: Each term found by the analyzer during the fit is assigned a unique integer index corresponding to a column in the resulting matrix. This interpretation of the columns can be retrieved as follows: analyzer 在拟合过程中找到的每个 term（项）都会被分配一个唯一的整数索引，对应于 resulting matrix（结果矩阵）中的一列。此列的一些说明可以被检索如下: The converse mapping from feature name to column index is stored in the vocabulary_ attribute of the vectorizer: 从 feature 名称到 column index（列索引） 的逆映射存储在 vocabulary_ 属性中: Hence words that were not seen in the training corpus will be completely ignored in future calls to the transform method: 因此，在未来对 transform 方法的调用中，在 training corpus （训练语料库）中没有看到的单词将被完全忽略: Note that in the previous corpus, the first and the last documents have exactly the same words hence are encoded in equal vectors. In particular we lose the information that the last document is an interrogative form. To preserve some of the local ordering information we can extract 2-grams of words in addition to the 1-grams (individual words): 请注意，在前面的 corpus（语料库）中，第一个和最后一个文档具有完全相同的词，因为被编码成相同的向量。 特别是我们丢失了最后一个文件是一个疑问的形式的信息。为了防止词组顺序颠倒，除了提取一元模型 1-grams（个别词）之外，我们还可以提取 2-grams 的单词: The vocabulary extracted by this vectorizer is hence much bigger and can now resolve ambiguities encoded in local positioning patterns: 由 vectorizer（向量化器）提取的 vocabulary（词汇）因此会变得更大，同时可以在定位模式时消除歧义: In particular the interrogative form “Is this” is only present in the last document: 特别是 “Is this” 的疑问形式只出现在最后一个文档中: In a large text corpus, some words will be very present (e.g. “the”, “a”, “is” in English) hence carrying very little meaningful information about the actual contents of the document. If we were to feed the direct count data directly to a classifier those very frequent terms would shadow the frequencies of rarer yet more interesting terms. 在一个大的文本语料库中，一些单词将出现很多次（例如 “the”, “a”, “is” 是英文），因此对文档的实际内容没有什么有意义的信息。 如果我们将直接计数数据直接提供给分类器，那么这些频繁词组会掩盖住那些我们关注但很少出现的词。 In order to re-weight the count features into floating point values suitable for usage by a classifier it is very common to use the tf–idf transform. 为了为了重新计算特征权重，并将其转化为适合分类器使用的浮点值，因此使用 tf-idf 变换是非常常见的。 Tf means term-frequency while tf–idf means term-frequency times inverse document-frequency : Using the TfidfTransformer "s default settings, TfidfTransformer(norm="l2", use_idf=True, smooth_idf=True, sublinear_tf=False) the term frequency, the number of times a term occurs in a given document, is multiplied with idf component, which is computed as , where is the total number of documents, and is the number of documents that contain term . The resulting tf-idf vectors are then normalized by the Euclidean norm: . Tf表示 词频 ，而 tf-idf 表示术语频率乘以 逆文档频率 : 使用 TfidfTransformer 的默认设置， TfidfTransformer(norm="l2", use_idf=True, smooth_idf=True, sublinear_tf=False) 词频即一个词在给定文档中出现的次数，乘以 idf 即通过 计算, 其中 是文档的总数， 是包含词 的文档数。 然后，所得到的tf-idf向量通过欧几里得范数归一化： . This was originally a term weighting scheme developed for information retrieval (as a ranking function for search engines results) that has also found good use in document classification and clustering. The following sections contain further explanations and examples that illustrate how the tf-idfs are computed exactly and how the tf-idfs computed in scikit-learn"s TfidfTransformer and TfidfVectorizer differ slightly from the standard textbook notation that defines the idf as In the TfidfTransformer and TfidfVectorizer with smooth_idf=False , the “1” count is added to the idf instead of the idf"s denominator: 它源于一个词权重的信息检索方式(作为搜索引擎结果的评级函数)，同时也在文档分类和聚类中表现良好。 以下部分包含进一步说明和示例，说明如何精确计算 tf-idfs 以及如何在 scikit-learn 中计算 tf-idfs， TfidfTransformer 并 TfidfVectorizer 与定义 idf 的标准教科书符号略有不同 在 TfidfTransformer 和 TfidfVectorizer 中 smooth_idf=False ，将 “1” 计数添加到 idf 而不是 idf 的分母: This normalization is implemented by the TfidfTransformer class: 该归一化由类 TfidfTransformer 实现: Again please see the reference documentation for the details on all the parameters. 有关所有参数的详细信息，请参阅 参考文档 。 Let"s take an example with the following counts. The first term is present 100% of the time hence not very interesting. The two other features only in less than 50% of the time hence probably more representative of the content of the documents: 让我们以下方的词频为例。第一个次在任何时间都是100％出现，因此不是很有重要。另外两个特征只占不到50％的比例，因此可能更具有代表性: Each row is normalized to have unit Euclidean norm: For example, we can compute the tf-idf of the first term in the first document in the <cite style="font-style: normal;">counts</cite> array as follows: Now, if we repeat this computation for the remaining 2 terms in the document, we get and the vector of raw tf-idfs: Then, applying the Euclidean (L2) norm, we obtain the following tf-idfs for document 1: Furthermore, the default parameter smooth_idf=True adds “1” to the numerator and denominator as if an extra document was seen containing every term in the collection exactly once, which prevents zero divisions: Using this modification, the tf-idf of the third term in document 1 changes to 1.8473: And the L2-normalized tf-idf changes to : 每行都被正则化，使其适应欧几里得标准: 例如，我们可以计算 计数 数组中第一个文档中第一个项的 tf-idf ，如下所示: 现在，如果我们对文档中剩下的2个术语重复这个计算，我们得到: 和原始 tf-idfs 的向量: 然后，应用欧几里德（L2）规范，我们获得文档1的以下 tf-idfs: 此外，默认参数 smooth_idf=True 将 “1” 添加到分子和分母，就好像一个额外的文档被看到一样包含集合中的每个术语，这样可以避免零分割: 使用此修改，文档1中第三项的 tf-idf 更改为 1.8473: 而 L2 标准化的 tf-idf 变为 : The weights of each feature computed by the fit method call are stored in a model attribute: 通过 fit 方法调用计算出的每个特征的权重存储在模型属性中: As tf–idf is very often used for text features, there is also another class called TfidfVectorizer that combines all the options of CountVectorizer and TfidfTransformer in a single model: 由于 tf-idf 经常用于文本特征，所以还有一个类 TfidfVectorizer ，它将 CountVectorizer 和 TfidfTransformer 的所有选项组合在一个单例模型中: While the tf–idf normalization is often very useful, there might be cases where the binary occurrence markers might offer better features. This can be achieved by using the binary parameter of CountVectorizer . In particular, some estimators such as Bernoulli Naive Bayes explicitly model discrete boolean random variables. Also, very short texts are likely to have noisy tf–idf values while the binary occurrence info is more stable. 虽然tf-idf标准化通常非常有用，但是可能有一种情况是二元变量显示会提供更好的特征。 这可以使用类 CountVectorizer 的 二进制 参数来实现。 特别地，一些估计器，诸如 伯努利朴素贝叶斯 显式的使用离散的布尔随机变量。 而且，非常短的文本很可能影响 tf-idf 值，而二进制出现信息更稳定。 As usual the best way to adjust the feature extraction parameters is to use a cross-validated grid search, for instance by pipelining the feature extractor with a classifier: 通常情况下，调整特征提取参数的最佳方法是使用基于网格搜索的交叉验证，例如通过将特征提取器与分类器进行流水线化: Text is made of characters, but files are made of bytes. These bytes represent characters according to some encoding . To work with text files in Python, their bytes must be decoded to a character set called Unicode. Common encodings are ASCII, Latin-1 (Western Europe), KOI8-R (Russian) and the universal encodings UTF-8 and UTF-16. Many others exist. Note An encoding can also be called a ‘character set", but this term is less accurate: several encodings can exist for a single character set. The text feature extractors in scikit-learn know how to decode text files, but only if you tell them what encoding the files are in. The CountVectorizer takes an encoding parameter for this purpose. For modern text files, the correct encoding is probably UTF-8, which is therefore the default ( encoding="utf-8" ). If the text you are loading is not actually encoded with UTF-8, however, you will get a UnicodeDecodeError . The vectorizers can be told to be silent about decoding errors by setting the decode_error parameter to either "ignore" or "replace" . See the documentation for the Python function bytes.decode for more details (type help(bytes.decode) at the Python prompt). If you are having trouble decoding text, here are some things to try: For example, the following snippet uses chardet (not shipped with scikit-learn, must be installed separately) to figure out the encoding of three texts. It then vectorizes the texts and prints the learned vocabulary. The output is not shown here. <pre style="padding: 5px 10px; font-family: Monaco, Menlo, Consolas, "Courier New", monospace; font-size: 13px; color: rgb(34, 34, 34); border-radius: 4px; display: block; margin: 0.1em 0px 0.5em; line-height: 1.2em; word-break: break-all; word-wrap: break-word; white-space: pre-wrap; background-color: rgb(248, 248, 248); border: 1px solid rgb(221, 221, 221); overflow: auto hidden;">>>> import chardet (Depending on the version of chardet , it might get the first one wrong.)

第1题time去掉第2题 a改成an第3题for改为of第4题drove改为drive第5题his改为their第6题正确第7题 have改为had第8题Be改为were第9题 lost 改为lots 第10题去掉in 第1题time是多余的，汉语说第一次访问，英语说my first visit便可。这一题是考查英汉语不同的表达习惯。如果一定要用time则可说my first time ro visit an American family 这时visit成了动词，visit之后就不能用to了。涉及到第二行出现了两个错误。不合题目要求。第2题考查冠词用法，不定冠词a与辅音开头的词连用，后面若是元音开头的单词，就要用an，把a改成an便可。第3题考查介词的搭配be kind of sb to do sth．把文中的for改为of．第4题连接词and连接的是两个并列的动作：meet与drive．需把drove改为drive．第5题考查代词的数。The Smiths用的复数，（指一家人或夫妇俩），后面的代词不能用is而应用their．第6题对。第7题考查动词时态的使用。整篇文章记叙过去发生的事，用的过去时；visited，was，did，offered，asked等，故have也应改为had．第8题考查形容词作谓语需加系动词的用法。eager是形容词，不能单独作谓语，在前边应添加be的过去式were．第9题考查名词复数的使用，lost of question不对，应说 lots of questions．第10题介词的使用不当。汉语常说在下一周，下一月，下一年，英语既不用on也不用in．只用 next week, next month，next year。便可。去掉in．与next的这种用法相似的还有this, last与one，它们与表示时间的名词连用时，不能再加介词。

我知道你想做

Negative后面跟to do something，be negative to do something.意思是对做某事感到消极

She is happy.

Today is the first day of the New Year, the morning of fresh air and sunshine, mother took me to feel the New Year"s day outside the atmosphere. Street vehicle comings and goings, flowing very lively, mother took me to the supermarket to buy things, supermarket bustling, originally people rush to buy New Year gift! My mother said he wanted to buy a toy, I say: "I is the big kid don"t car these toys, it would save some money to buy school things," then I will take some learning supplies and a cake billet to do our own cake to celebrate New Year"s day. On the way back to my grandma"s I saw many shops, supermarkets in glass written on New Year"s day wishes everybody happy, return to my grandma"s I took the cake billet and brother in above the text is made. Less than half an hour a nifty bright homemade cake will appear in the present, this is really a happy New Year!

Today is a new day.I open my eyes with the first sunray shinning through the window.I breathe the fresh air from the green forest.I love today,because everything is new,including myself.I love today like I love every moment coming to my life!纯手工，感谢您的支持~

是不是Celine Dion的a new day has come

意思是今天是新的一天1.today[英][təˈdeɪ][美][təˈde]adv.现在;现今;（在）今天;现代，当代;n.现今;今天，今日;现代，当代;2.new[英][nju:][美][nu:]adj.新的，崭新的;新鲜的，新到的;现代的;初次（听到）的;adv.新近，最近;3.day[英][deɪ][美][de]n.一天;白天;时期;节日;adj.日间的;逐日的;adv.每天;经常在白天地;主语应该是名词today是名词意思是今天new是形容词意思是新的day应该是名词所以意思是今天是新的一天它的寓意就是过去已经过去了，我们应该注重当下才是最重要的，毕竟今天是新的一天我们可以重头再来

to do 作状语一般是表目的而doing则是指那个状态比如说He did his homework,listening classical music.他听着古典音乐在做家庭作业To get a satisfying score,he devoted his much time and energy to studying.为了取得一个好成绩,他把大量的时间和精力都投入到了学习上

今天是崭新的一天

崭新的一天

原来是英法混合的～ 其中法语部分如下： Ma Mela je suis tres desole 我的美拉，非常抱歉 My Mela I"m so sorry Je pense que tu es atrayiant （打错了，是attrayant） 我想你很有魅力 I think you"re attractive I"ll come to you par avion 我要坐飞机来找你 I"ll come to you by plain I do not want to lose you Je tu voudrais ici （打错了，应该是je te voudrais ici） 我想要你在这里 I want you to be here And I want you Ma bell petit ami （打错了，应该是ma belle petite amie） 我漂亮的女朋友 my pretty girlfriend

非AutodeskDWG。此DWG文件由非Autodesk开发或许可的软件应用程序保存。将此文件与AutoCAD软件一起使用可能导致稳定性问题。DWG文件确实是Autodesk公司定义的一种图纸格式，AutoCAD提供了两种常用文件格式：DWG和DXF，其中DXF是公开的，用于和其他软件进行数据交互的。但DWG文件成为大多数设计人员标准的工作文件，很多软件希望能直接读写DWG文件，而Autodesk公司只是对少数合作伙伴公开DWG数据格式，因此就产生专门研究DWG兼容的组织：OPENDWG，这个机构后续又提供了兼容DGN（Microstation文件）的技术，组织更名为：Opendesign(简称为ODA)。由于很多厂商利用ODA的模块开发出一些完全兼容、且功能类似于AutoCAD的产品，对AutoCAD的销售造成了冲击，Autodesk公司对此非常不满，在某个版本开始在dwgcheck中加入了对DWG文件的判断，如果DWG不是由AutoCAD提供数据接口保存的，就会弹出警告对话框，即使将dwgcheck变量设置为0，在打开文件后，会弹出上述提示。后期Autodesk和ODA的关系有所缓解，AutoCAD高版本好像不弹警告对话框了，只出打开文件后除命令行提示。ODA模块保存的DWG图纸，和AutoCAD的DWG图纸兼容性相当高，相互之间进行保存读取没有任何障碍，因此看到这样的提示不必担心。

it will be hot today 是对的

因为will后面需要跟动词原形，所以用beshe will be here today.她将今天来。

used to do和used to doing的区别：中文含义不同、用法不同。used to do中文意思为“过去常常做某事”，是一般过去时时态; used to doing中文翻译为“习惯于做...…”，to是介词，后面要跟名词、代词或动名词形式，是一般现在时时态。used to do和be used to doing的含义不同，be used to doing表达习惯于做某事的意思。used to所表示的意思是“过去常常做某事”，强调过去发生的事，所以一般用于描述发生在过去的事情。used to do的含义及用法介绍used to do意为过去常常做某事，即现在不做某事了。例句有:1、l used to do that when you were a little girl, remember?在你还是小女孩的时候我曾经那么做过，记得吗?2、The lecturer used to do well, but he seems to have gone off now。这个讲师以前挺好，但如今似乎讲得差了。3、After all, that is what China used to do。毕竟过去的中国一直就是这么做的。4、Finally, an example is used to do analysis。最后佐以一个案例分析。5、Property can be used to do the same for a form。属性也可以在窗体中实现同样的功能。used to doing的含义及用法介绍used to doing意思为习惯于做......，后面可接名词、代词或者动名词。例句有:1、She used to bully me into doing my schoolwork她过去总是强迫我写作业。2、People here are used to doing for themselves。这里的人对自救已经习惯了。3、You get used to doing your own business on your own time。你们必须学会用自己的时间做自己的事。4、In the end, l got used to doing the hard work。最后，我终于习惯干苦活了。5、That is because women can continue to do something they are used to doing。那是因为妇女能继续做他所一直习惯做的事情。

一共是三个Be used to do 被用于，被用来做什么标准被动语态The box is used to be a rubbish can.这盒子被用来当垃圾桶。Be used to doing 习惯于I am used to Get up at six.我习惯于早六点起床used to do过去常做，但是现在不这么做了I used to Get up at six.我过去常常六点起床，（但是现在不这样了。）手打完毕，希望有帮助。

todosomething将要进行某事时用,有些动词后面用 to dodoingsomething正在进行某事时用,系动词后面用 doing

"Start to do something" 和 "Start doing something" 基本上是相同的，都表示已经开始做某件事情。但在某些情况下，它们可以略有不同的含义。"Start to do something" 表示打算或准备开始做某件事情。它强调的是一个行动或目的的意图，比如：- I need to start to exercise more regularly.（我需要开始更规律地锻炼身体。）在这个例子中，人们指的是他们想开始锻炼身体的意图或打算。"Start doing something" 则表示正式或实际地开始做某件事情。它强调的是一个行动或目的的实际执行，比如：- He started doing the homework right after dinner.（他晚饭后就开始写作业了。）在这个例子中，人们指的是他们实际开始写作业的时间。总之，"Start to do something" 和 "Start doing something" 的含义很相似，在一些情况下可以互换使用，但在一些细节方面可能存在一些微妙的差异。

to do the best myself的中文翻译to do the best myself 做最好的自己双语例句1Anne: The most important thing for me now is to do the best possible job for thecompany and improve myself through working. 安妮：现在对我来说，最重要的是做好我的本职工作，在工作中提升自己。

night啊 昨天今天明天 都是 时间状语 而夜晚是表达时间的名词!

两个全是祈使句 没语法错误 前者比较好 因为英语和中文一样要避免重复 后一句中两个do意思一样且重复 应该省略动词不定式 即省略to do

be careful 可以跟不定式 和从句 be careful to do sth be careful 加名词性从句其他跟介词 的用法 是介词本身的用法 除了 be careful with 和 be careful for以外还有 be careful in doing ,be careful about sth, be careful of sth 并没有be careful doing的用法

enduptodo指停止做，doing指先停止再去做。根据百度信息显示，enduptodo指停止做，代表一件事的结束，doing指先停止再去做，代表一件事的开始。区别是一个汉语词汇，有区分、辨别的意思。

Time和time_of_day类型可以转换成DINT（双整数）

+doing，由于out是介词。figureout的意思是：想出;解决;计算出;弄明白1、作名词的意思是：数字；人物；图形；价格；（人的）体形；画像2、作不及物动词的意思：计算；出现；扮演角色3、作及物动词的意思：计算；认为；描绘；象征扩展资料figure的用法：1、figure可用作及物动词,也可用作不及物动词。用作及物动词时后接名词或代词作宾语。figure还可用作系动词,后接名词作表语。2、在非正式英语中,figure可表示“认为”“料想”,这时多接that从句作宾语,也可接以“(tobe/as+)n./adj.”充当补足语的复合宾语。3、figureon是美国口语,意为“指望”“信赖”“打算干”,其后可接动词不定式,也可接动名词。4、在美国口语中还可说figureup,意为“把?加起来”。5、figureout和figureup意思相近，在美国英语中解释为“计算”或“估计”。

这里to是介词，所以后面要加名词或者动词的不定式。动词不定式是指动词的一种不带词形变化从而不指示人称、数量、时态的形式。
