有各选项要点解析,还有比如情态动词,最好可以通过1题解决一系列问题,

1.-what's the matter with the computer?the system crashed.-someone____have used it while you were away.A,shall B,could C,should D,needBA2.In history,literature,English and foreign language classes,reading and comprehension skills____be the difference
1,could表示推测,shall用于第一人称
2,这是客观真理,用can.（老兄你很喜欢shall啊,但是这个用的几率不高哦）
3,虚拟语气,因为这是不可能发生的,只是假设.
4,beyond是介词,不能做介词,所以which不对（你认为是宾语从句吧,是句子的话要有主谓宾）
6,这句话的意思是当什么什么的时候她正好怎样怎样,as这个词有点淡淡的因果关系的味道
7,这里的try是审讯的意思,主语是受动者,所以要加be动词
8,选C吧,应该在b与c之间徘徊,这个怎么没答案呢
9,c和d的感情是不一样的,这里老板应该是有点训斥的味道的,因为是大错误,而d则含有保重的味道,不合语境
10,a是词组的意思,c是解释的意思,这个查查字典就出来了
11,c,因为是两者中的另一者,所以用the other
12,but for意思是“要不是” 例句：But for the raining we should have a basketball game.
13,that's a deal 意思是一言为定
14,one可以指代的东西可多了,人事物都可以,用于单数,复数的话还有个ones可以用
15,by+数量词表示幅度
一劳永逸是不可能的,归纳这种事要自己做才有效,（很多教参上归纳的这么好但是你看了也没多少感觉的,）只有自己做过了才能体会,才能一通百通.英语靠的是积累,做多了感觉就出来了,有些题目就是不知道道理也能找到答案,这就是语感.
还有就是单选的话要注意动词,这是考的最多的.平时常用的介词,词组等的注意下下就好了,题做多了你会发现其实老师都是很没创意的,中考和高考也一样
(毕业好久了,讲的不详细,见谅）

1.shall一般是用在I、WE的，一人称~
shall I?shall we?
2.同上。
3.同上，再排除法
4.这里要是作为定语从句，也不能用which,因为没选择性，要用what。这样排除，就是something啦。something这里是个省略句，(That's)something....
6好难哦，我跟楼主答案一样。
7，他说sent t...

2.同上。

6好难哦，我跟楼主答案一样。
7，他说sent to poisen,是过去式，前面说他判刑什么的就是完成时啦~to be 之类表将来
8.估计选C?then表示当时，就不选D啦。这里有点选择性。
9.take care多有保重身体，（小心着凉~）之意。Be careful是注意，当心，有警告之意。
10.理‘字’感觉就像人的表情，我个人感觉好像就是感情传达之类的，而C好像是完全无感情的解释……呃，A是比较合适~~~
11.C
other 是同类中，除其一的任意一个。比如非你不嫁，就是i don't marry other boys except you.
another是另一个的意思。i don't like this dress,give me another
the other指两者中的另一个，或者一堆里面，除了一个剩下全部的。不过搭配有些词时会变 ，当固定短语吧。
the other day，另一天
the other one另一个
others 区别于the other,是指一堆里面除了一个，剩下不全部的。
