Question

It's impossible far all the people to get jobs because ________ of them are not

It's impossible far all the people to get jobs because ________ of them are not fit for them.
A. none
B. all
C. not all
D. every one

Answer 1

答案B
注意主句实际上暗含有部分否定，表示不可能人人都能有工作，因此从句也用部分否定，而句中已有not，因此说all…not或every…not．此题从句动词是are，D项不对。
