希望配有详解,
保证答案准确率!
1.A
than是关系代词,引导定语从句.它等于先行词work,并做该从句的主语.
而选B的话,则从句中的to be put无法做句子的谓语.
2.B
was he afraid视为插入语,放在疑问词what之后,其后用陈述句序,what刚好做would happen的主语;
A中的that多余
3.A
现在分词的否定形式,一律是在Ving(题中是having)前面加上not
4.A
固定短语 hunger for sth,意思是“渴望某物”;
for which she hungered = she hungered for which = she hungered for the letters
即定语从句中的关系代词which代指先行词the letters,在从句中充当hunger for的宾语.
