Answer 1

21，第一空中，他去老师办公室，后面的一句话表目的，用to加动词原形表目的，为了和老师说再见，而说再见是对老师说，所以用to,就好象 He give it to me.
22,这里表示阻止某方面的事情发生，用from 来表明某件事，而from 是介词，所以后接动词ing.
23,就题目本身看，side后面没加s,所以把A,B排除（另外all只能修饰三个或三个以上的事物）。题目中是用side of the street ,所以用each,如果用D的话，就要改为every street side.
24,这是一个宾语从句，us 后面省去了that,所以told有宾语，不用再加it.
25.A用于特指两个中的另一个，B和C都是泛指其他，但C只能作宾语。而D则是表示同类的其他。
26A明显排除，不可能同时出现两个介词。此句是想用比较级，Happy的比较极是happier,而much只是修饰happy，不用比较极。
27，A是三者或三者以上都不，B是两者都，C用在否定句或疑问句中，D是两者都不。
28，busy 后面省了in,该句式是be busy in doing sth.而get ready for是一个固定短语
29，这是一个宾语从句，hope 后面接一个完整的句子。
30，这是固定搭配，that表示yesterday,而比较的是天气，加of表示昨天的天气.

Answer 2

21 B 目的状语 ；say goodbye to sb 向某人告别
22 D stop sb from doing sth 阻止...做。。。across 介词 cross 动词
23 D side 是单数，every用于三者以上，街道只有两边
24 C what to do; how to do it; when to do it.比较一下。
25 A them暗示特定群体，加the
26 题目有问题吧？答案该是 on the night
27 several暗示三者以上，A和C可以，但是BUT，说明用none
28 be busy doing sth; get ready to do 结合看
29 hope 不可以hope sb to do,可以接宾语从句或hope to do
30 that 指代前面的天气。of 从属
