have been doing ,have done和have doing区别

Have/has been 后一定要加doing sth.吗?

不一定的,为什么呢?因为请看如下句型:Havehasbeen+doingsth.--->的话它是现在完成进行时的句型。Havehasbeen+donesth.--->的话它是现在完成时的被动语态的句型。而Havehasbeen后还可以加形容词的。

since...+have been doing

have been doing sth 表示到现在为止一直在做某事情,而且有继续做下去的可能! have +过去分词 表示的是已经完成了什么事情! 见since 之类的词,大多数用have been doing sth ,因为是从某时刻开始,基本上到现在还在延续~ 不知道我的回答清楚么? *_*

be doing sth 和 have been doing sth 有什么不同?

希望对你有帮助,请采纳

have been doing 的用法,

相同:1:现在完成时(have done)和现在完成进行时(have been dong)都可以表示从过去某一时刻开始一直延续到现在的动作。Example:I have worked in this school since 2000.I have been working here since 2000.2:现在完成时和现在完成进行时都可以表示一段时间内延续的动作。Example:Mr. Smith has lived here for 20 years.Mr. Smith has been living here for 20 years.以上句子用现在完成时和现在完成进行时,含以上没区别,两种时态可互换。但两种时态也存在用法上的差别。

have been doing sth 什么意思

现在完成进行时的标准结构表示到当前已经进行一段时间且还在进行中IhavebeenlearningEnglishfor3years.

have been 加过去分词还是doing?

1 现在完成进行时,表示过去发生的动作或已经完成的动作,现在仍然继续,并且还将进行下去.构成结构是:“have been +doing” 2 现在完成时,表示过去发生的动作对现在造成的结果和影响.结构是:“have+过去分词” 3 这两种时态的区别是:现在完成进行时表示动作还将继续并进行下去,表示动作继续.而现在完成时表示动作已经结束. For example,I have been collecting old coins for three years.(我已经收集古币三年了,说明现在还收集.) I have collected old coins for three years.(说明只收集了三年,现在不收集古币了)

have been doing 的用法有哪些?

现在完成进行时是什么意思have been doing 用中文怎么说

drdtcyvtcezez

was been done 和be done doing 还有have been doing的用法含义...

注意:这里wornout是形容词(adjective)性的短语,不是动词(verb)。所以,在“Histrouserswasbeenwornout”中,只有“wasbeen”的短语是动词,符合一个句子一个动词的标准。bedonedoing是现在完成时的被动形式。强调不久前刚发生事情持续到现在用havebeendoing的现在完成时态,被动即是bedonedoing。havebeendone是现在完成时态的被动形式。现在完成时态基本结构为have+动词的过去分词。

have been doing是什么时态?

have been doing是现在完成进行时,表示已经做了并且还在做的事情。have been done 是一般现在时,表示已经完成的事情。英语完成时、进行时,既可以作为两个相对独立的时态,也可以组合为一种新的时态,即“完成进行时”。完成进行时是从动作的持续状态的角度来看待一个动作的。如果再从时间的角度来看,它又可以分为过去完成进行时、现在完成进行时、将来完成进行时以及其它的一些时态。下面结合实例,来简要地叙述一下完成进行时的用法。如果单独看完成时态,它有一个基本的含义即表示到某个时间为止,该动作已经完成,所以它称作“完成时”。但是,在完成进行时里面,一般情况下,它并不表示动作的“完成”,而是表示长时间的持续状态。也就是说,完成进行时侧重于“进行”。如果单独看进行时,它表示某个时间内动作正在进行,而完成进行时则侧重于长时间的持续状态。如果简单地说,完成进行时实际上是一种强调动作持续发生的进行时,并且含有动作反复进行的意思。以上就是完成时、进行时、完成进行时之间的联系和区别。参考资料百度百科.百度百科[引用时间2017-12-20]

it is no use doing what you like you have got to like what you do

Growing up in a small town near Lahsa, I loved watching all the wildlife in the Tibetan Plateau. I loved seeing the magnificant condon soaring high into the sky, the sleek snow leopards, the galloping Tibetan argali, and all other wild animals. These are my best friends in the home on the Plateau. However, over the years, I also saw these wildlife gradually disappearing. They were killed by poachers and the loss of habitat. Although I love watching these animals, but I feel so helpless because I don"t know how to save them.I am sure all of you, at some point of you life, had some what similar experiences when you loved doing something, but you felt it"s not very useful, because you couldn"t help if things were getting bad. When situations like these araise, the best thing out it to do something that could change the situation, and enjoy doing so to make a commitment.Back to the wildlife in my hometown. After a couple of years aggravating on what was happening to the wildlife, I finally realized that I have to do something to stop this downturn trend. I started a research project documenting the habitat use of these wild animals in order to persuade the conservation agencies to protect their habitat. At the beginning, the research project faced a lot of difficulties: I didn"t have enough funding and the winter was harsh outside conducting surveys. But I enjoyed what I was doing, because it gave me hope, that eventually all this hard work will payoff. Two years later, my study results finally came to fruit, and a large area next to my home was declared a natural reserve and off limited from hunting and development. Nowadays, I"m still working as a conservationist in the region. Work is hard and life is tough. But I like what I"m doing. I"m seeing the wild animals are coming back and feel a sense of fulfillment. I"m happy now. Therefore, it"s really no use doing what you like. The point is, you"ve got to love what you are doing.

Have you ever seen the man in the moon ?的意思,急急急!!!!!!马上,跪求, 十分钟内

你可曾看到了月球上的人?如果你夜晚仔细地看月亮,你可以看到在月球上有人脸。有些人说,他们可以看到一个老人携带棍棒。其他人看到一个女孩读书。这些画面是由月亮上山区和平原构成的。 很久以前,人们在英国曾经告诉自己的孩子,那是由绿色的奶酪构成的。大家都知道,这是不正确的。月亮是一个大的圆形石头。上面什么都没有。没有树木或植物在月球上。也没有河流或海洋。更没有活着的东西。没有空气。雨也永远不会出现在月球上,一切都覆盖着干的,白色的粉尘。甚至没有一个可以听到的声音 出现在月球上。 当阳光照在它的上面时,月球非常热。但是,在背面却是非常冰冷。 月亮是比地球小。它并没有地球的重量。如果你去了月球,比你现在,你就只有六分之一的体重了。即使是一个胖子在那儿,也能够跳得很高。
