两道初中英语题目.

Question

1:将“They were here yesterday.”改成一般疑问句、问时间的疑问句和否定句.
2:将“He must leave early”改成一般疑问句、问原因的疑问句和否定句.
请大家解释一下为什么要这样改.谢谢!

Answer 1

1.Were they here yesterday?
When were they here?
They weren't here yesterday.
2.Must he leave early?
Why must he leave early?
He needn't leave early.

一、先解释下特殊疑问句吧，

首先~因为是改成时间、原因的疑问句，疑问词选择when问时间，why问原因。

然后，因为是疑问句，规则是把情态动词或者be动词提到疑问词之后，主语之前。
这两个句子中，就是“把be动词were提到when之后，they之前”，和 “把情态动词must提到why之后，he之前”。

第一个句子是问时间，所以要把 yesterday 这个时间状语去掉。

二、一般疑问句

变一般疑问句的规则是，直接把情态动词或者be动词提到疑问词之后，主语之前。

如果会特殊疑问句了的话，这个也很容易操作了

三、否定句。

直接加not在be动词和情态动词后面。

但是要注意， must是个特殊的，需要记住改否定句 应该是need not。

Answer 2

1.Were they here yesterday?
When were they here?
They weren't here yesterday.
2.Must he leave early?
Why must he leave early?
He needn't leave early.
其实很简单。一般疑问句就是be动词提前或情态动词提前
特殊疑问句是疑问词加一般疑问句
否定句就直接在be动词或情态动词后加not
must特殊要改成need本回答被提问者采纳
