Question

1.The students are having a concert (to raise money for charity.)

2.I don't know what I should say at the meeting.（改为简单句）
I don't know ( ) ( ) ( ) at the meeting.
3.Paul is looking for Mary. He can't find her. So he asked me..
"Where ( ) Mary ( )?" (完成问句）
如果可以请告诉我为什么这么填 谢谢。

Answer 1

1. What,for
括号里的(to raise .... for charity ) 表作用(目的), 当要提问时, 用" What ...for ?" 来询问作用(目的).
例句: What is it for? (它用来干什么的?)

2. What to say
a. 主句和从句的主语一致,都是"I", 可将从句里的主语"I"省略;
b. What I should do(完整句) = What to do (简单句).
例句: I don't know what I should eat. = I don't know what to eat.

举一反三: I don't know where I should go. = I don't know where to go.

3. has,gone
"has gone"表示去了某个地方还没回来.

希望以上答复能让你完全理解,懂得灵活应用.
满意就赏分吧! :)

Answer 2

1.what.....for
动词不定式表示目的
2.what to say
3.has gone？

去哪里了。

Answer 3

1)what；for
不定式to raise money for charity 是are having a concert 的目的和原因
what for 表示原因，相当于why
2)what to say
wh-的从句皆可用wh- to do 的形式替换
3)has; gone ?
has gone表示“去了某地”也就是说，提到的那个人还没回来，不在现场。

括号里是音乐会的目的，为慈善捐款，所以提问要问为什么开音乐会

玛丽去哪儿了

Answer 5

1.what.....for

Answer 6

对划线提问，他们开会的目的是什么

2.what to say 要说什么
what 做say的宾语

3.has gone
用完成时
因为找玛丽，是在他走之后，所以用完成时
