Answer 1

1. 这里说的是虚拟语气，所以不选A咯。再说有knock过一次了，你总不能还用现在时去表达之前的敲门

动作吧？
2. would表愿望、请求，could表可能性、允许。
3. 要用on的话 得加the，但也表达不了通过电话的方式这个意思。这里的could是表过去的能力。
4. A的walk要变walking才对
5. rain这个已经的完成的动作了，在我知道之前就完成了。
6. 这个不需要释疑了吧？D没有这样用的 be not，
7. 这里说了两种，boy和girl，如果是every boy and girl就可以是is，但没这样表达的。
8. 这里说的事物的抽象概念 不可数
9. 主句就是个one pair了
10.这里虽然有two啊但它两个单位gallon，而表达的是gas液体，不可数的。不要跟上面的裤子混淆，裤子因为有两条裤管，一直都是用复数的，这是习惯了。
11.看英文吧rob：To take valuable or desired articles unlawfully from
snatch：To grasp or seize hastily, eagerly, or suddenly.
12.这里是要用张贴的意思，就put up 符合
13.bring up是抚养长大的意思
14. 挂电话只用hang up，用hold是说别挂电话
15. put it 提出，mean it认真
16. take sth as 把什么当做什么
17. observe遵守、庆祝To keep or celebrate (a holiday, for example)， 国外居住多年，很多中国人还是保留传统风俗。

Answer 2

1 考察的是情态动词的用法，推测是表示否定是要有could,语气较弱。
2 could表示推测，而would有表将来的意思。
3 用by表示方式，by phone是固定搭配，前面用的是tried,所以为了时态一致要用couldn't。
4 dare to do sth 敢做某事 是固定搭配。
5 last night 可以看出要用过去时。
6 情态动词后面直接接否定，不需要再加be动词。
7 every 每个人 所以要用单数第三人称。
8 the +形容词表示一类东西，谓语动词要用单数第三人称。
9 One pair才是主语，所以用单三。
10 gas本为不可数名词，所以用单三。
11 rob意为抢劫 而 snatch侧重表示抢走了。
12 set up意为建立，设立。 put up意为张贴 根据句意可以判断选put up.
13 bring up 带大，养大，build up 为强身健体。
14 hang up 是挂电话，固定搭配，而hold up是让别人别挂电话。
15 put sth 有表强调.....的意思
16 take sth as为固定搭配，意为把....视作....相当于regard....as \treat....as
17 observe 遵循，遵守，而perform意为表演。
