Question

he is working hard for fear that he＿＿

A，fails B，failed C，would fail D， fail说出原因
答案D ，既然是虚拟为啥不能选C，很不解啊

Answer 1

选C

这是一个虚拟语气句型。
由连接词in case, so that ,unless, lest ,for fear that引起的状语从句中，谓语动词要用虚拟形式，即should(might, would)+动词原形。

他刻苦学习以防考试不及格

should在虚拟语气中可以省略，这个题目不严谨C和D都是正确的

希望帮到你

Answer 2

你好。答案是C
语法：
1 for fear that + 句子（谓语动词通常是may / will + 实意动词）
2 for fear of doing sth
3 He is working hard for fear that he may / might fail
===He is working hard SO THAT he won't / wouldn't fail.
====He is working hard IN ORDER NOT TO fail.

Answer 3

C
楼上胡扯淡。由句意知，他还没有尝试，更谈不上失败，所以AB错误，D语法错误。没有这种虚拟语气的用法！只剩下C了，C表示将要发生的事。

Answer 4

D
不知道的不要误人子弟 for fear that . lest. in case 后接虚拟should do
should可以省略

Answer 5

选C
for fear这是个虚拟语气句型，后面要讲would should等词。
根据句意，用would比较合适
