（b）last month,part of Southeast Asia was struck by floods,from___effects the people are still suffering.

Answer 1

你只要记得 在定语从句中 1. all that = what
2. 定语从句中 介词后 不出现 that。

Answer 2

1.他的兄弟做了一切他能够做的，只有what能做两个成分，在主句和从句中都做宾语。意思上也只有what能通
2。有了逗号且没有连词，后面的就是从句，所以必须有连接词，这里只有whose意思最对。

Answer 3

1.what=all that, B中what应该为that
2. from是介词，后边不能跟that

Answer 4

all which=what，

Answer 5

1. 要用all的话应该是all that的宾语从句
(其实答案的all 就是省略that的宾语从句)
而想用what引导的宾语从句的话
直接用what 就可以了: his brother did what he could do to help him.
注意多了个"do"作为what从句里的谓语
2. 根据后半段"the people are still suffering"可知
effects在这里是名词
that 后面直接跟名词,而后边又是完整的句子
不合理啊...
