Can you think of some cases____people are likely to tell lies?A that B as C where D when 答案为什么是whereShe is adiligent student,and all her spare time she has_____staying in the library.A is spent B spent C to spent D to be spent

1，因为有case作为标志词，where的应用属于固定的从句搭配。
2，应该是b，，把all....she has作为一个意群理解，spent与前面的is同级并列，划分层次。
希望有帮助

cases做先行词引导定语从句，后面的句子中不缺成份，cases相当于做后面从句中的状语，所以用where来代cases…第二个选A，后面的空所在句子没有谓语，就相当于是she spend all her time staying in the library.把time提前用被动形式

C
where =in the place which
A all her spare time ( that/which she has) is spent
staying in the library

1. case 作先行词时就用where 引导定语从句
2. A

Can you think of some cases____people are likely to tell lies?
A that B as C where D when 答案为什么是where
这里是场合,不是具体的时间.
在很多时候,我们觉得用when习惯的地方,英文里都用where.
She is adiligent student,and all her spare time she has_____staying in the library.
A is spent B spent C to spent D to be spent
答案是A.
all her spare time she has中的she has 是修饰time的,所有她拥有的空余时间.
空余时间都被用来花在图书馆里了.
这里用被动语态.
