为什么选择这个理由，谢谢

Answer 1

D 十分虚弱， very是程度副词，修饰weak
D three-feet deep 形容词作定语，修饰hole，three和feet中间要用连字符
A much修饰不可数名词room，程度副词too修饰much，表示太多
B It's necessary for sb（主格） to do sth或It's necessary+ that从句 表示做某事很有必要
him是主格he的宾格

Answer 2

1. D     such 修饰名词   ；too`````too                                                                                                    
   

2. D  a/an +可数名词；两个名词用连字符链接修饰名词相当于形容词
   

3. A much修饰不可数名词，too much+n 固定搭配
   

4. B It's necessary that....../It's necessary for sb.to do sth. 因为句子是强调立即还书的必要性是一件事，所以用从句。
