【評論主題】24. David never tells his parents ______ on the Net. His parents worry about him.(A) who is he chatt

【評論內容】

David never tells his parents who he chats with on the Net.  

問句的話 Who does David chat with on the Net? 

但是只要是用關代子句，子句中一定變成主動型態 

如下

黃色部分可替換成可以替換成 

David never tells his parents the person he chats with on the Net.   

David never tells his parents the person who he chats with

on the Net.

用when/where 的句子如下

Where

David never tells his parents the place that/which he went to  that day.

David never tells his parents the place where he went  that day.

David never tells his parents where he went yesterday.

注意 使用where時， 子句後面的介系詞就要拿掉如went to 的to就不見

When 

David never tells his parents when he went to the beach that day.

David never tells his parents the time when he went to the beach that day.

what= the thing that 

I don't know what(the thing that) you are talking about. 

可以當主詞

What stood there in the window yesterday turns out to be just a giant mannequin. 昨天窗裡佇立的東西結果只是個大型人體模特兒。

A 選項 不可能 David never tells 是一種陳述一直以來的事實，因為never 是從未的意思，he is chatting with 雖然是主動 但是情境不符合， 應該改成 David doesn't want to tell his father who he is chatting with. 就可以
