Question

What made Mary so unhappy? -____her watch. A.Because of losing B.Because she lost

Answer 1

两个答案均不正确
正确答案应为Losing
提问的是“什么使到Mary不开心”
所以 你的回答必须是 __________ her watch made Mary unhappy. 答语后半部分被题目省略了
语法分析 这个答语缺少主语 只能使用Losing作为主语 AB两个“because”只能充当状语 不能充当主语

补充一下 AB两个答案都是用来回答“Why was Mary unhappy?”这句话的

Answer 2

B。 BECAUSE SHE LOST HER WATCH
A选项的话， BECAUSE OF LOSING HER WATCH，只是个短语，不是完整的句子，其实两个都说得通，但是正式考试那些，就要选B

Answer 3

b

Answer 4

B

Answer 5

A和B都不对。A是短语，B是半句话。正确答：
She lost her watch.
或 Mary was unhappy because she lost her watch.
或 Losing her watch made Mary so unhappy.
如果一定要选，what 问句，答 A, Why 问句，答 B
