为解压过滤举几个例子,2.纸层析法分离铁离子和铜离子实验中，展开剂的成分为丙酮。为什么？3.如何分离硝酸钾和氯化钠？

数学成绩的高低并不以压轴题为准的,你确定你基础的题都会做了么?除了压轴题你其他题目都得满分了?如果不是的话何必纠结于一道很难得分的压轴题?能够解出来就解出来,解不出来也不要太纠结于此.压轴题是给那些考清华北大的人准备的,如果你不需要考那么好的话就没必要纠结于此.如果你有那么高的理想,那你就可以放弃了,压轴题从来都解不出来的话甚至都没思路的话何苦去考那么好的学校呢?
当你掌握好了你会的内容就是成功了,不要丢西瓜捡芝麻,结果芝麻还捡不起来.

Due to the fast rhythm of modern life, more and more people are living under great stress.
People have to work hard to be admitted to universities, to land a job with a good company. To sum up, pressure arises from the fierce competition for a better position in society. Although proper pressure may help tap their great potential, too much stress result in anxiety, sleepiness, or even sickness. To relieve stress, some take up cigarette smoking, while others turn to alcohol drinking. Some even go to such an extreme that they take drugs, which does great harm to their physical and mental fitness.
In the face of great pressure, I think, we should adopt an optimistic attitude. Make a good judgment of ourselves and concentrate on what we can achieve because a person who knows what to give up can get what he can. Moreover, listening to music, doing sports, chatting to friends and being close to nature are excellent methods to keep ourselves free from stress.

" Someone has said that travelling is a stress-relieving way for the heart.Now I'm going to introduce my holiday to you.
The first place where I have been during this hoiday was the Lingding Island.Have you ever heard of WEN Tianxiang's "Cross the Lingding Ocean"?The island is just located on the Lingding Ocean.I was staying there for two days.I went swimming for the first day when the weather was so hot.The sun shattered me,while the sea water made me feel very cool.After swimming,we went climbing the mountain.I felt very comfortable when the sea breeze brushed my face.The night scene there was so beautiful,which made me feel very romantic.Returning from the mountain,I went to have some seafood because I was hungry.I still can't forget the flavor of the seafood there even by now.I can't even describe its taste with words.What a beautiful small island!I 'll definitely come back again next time.
The second destination I went was Hongkong where is well-known for the title of "shopping paradise".So I went there for shopping crazily.The majority things that I bought this time were:books,chocolates,albums and so on.The most important thing was that I had the icecream which couldn't be found in the mainland.The hotel in which I was staying is on the Nathan Road.It is very luxury.What excited me very much was that it also provided wifi for the customers.In fact,what was more excited to me was not about the wifi,but my coming across with Joey Yung.These are the pictures which were taken by myself.I feel that the trip to Hongkong was very pleasant rather than tired.
I hope that I can visit more places of interest next holiday.I love this summer and this holiday."

correctly,正确的

A,正确
B,错.错在“有一点误差”,无损压缩,当然要求一点儿误差都没有
C,错.“不失真”多指视觉不失真,其实像素值可能有很小变化,肉眼看不出来,也称为“不失真”,但显然已经“有损”
D,错.跟B一样错,无损压缩不能有任何的误差

所谓“互相解压”就是一起解压，这种说法是因为两个压缩文件中有同名文件夹
楼主不用把它想得太复杂，只要把两个压缩文件放在一个空文件夹中，同时选中它们在上面点击右键，选择“解压到当前文件夹”，如果提示覆盖文件夹，点“是”或者“全部”就好了
