一般疑问句的法则 和变为否定句

一般疑问句的法则 和变为否定句
急 明天就考试了

1.将陈述句变为一般疑问句时,如句中有be 动词(am is are …)时,可直接将它们提至主语前。如主语为第一人称,应将其改为第二人称。如:
I'm in Class 2Grade 1. →
Are you in Class 2Grade 1?
We're watching TV. →
Are you watching TV?
2.陈述句中有情态动词(can may must …)时,也可直接将它们提至主语前,即可成为一般疑问句。如:
He can swim now. →
Can he swim now?
The children may come with us. → May the children come with us?
3.陈述句中只有一个实义动词作谓语且其时态为一般现在时,变为一般疑问句时要在句首加do或does 主语后的实义动词用原形。如:
I like these animals. →
Do you like these animals?
She wants to go to the movies. → Does she want to go to the movies?
4.一般疑问句有时不用yes或 no 回答。

Are these oranges?
No, they aren't.

改成一般疑问句时,系动词放到前面来就可以,其他不变。

句子中的this, that, these, those 这四个词称作“指示代词”,用于指代人或物。This与that 相对,these与those 相对,this 的复数形式为these, that 的复数形式为those, 并且在做肯定或否定回答时,用it 来代替this 或that,用they 来代替these 或 those。

再例如:
This is an orange.
改成一般疑问句就是:Is this an orange?
做肯定回答:Yes, it is.
做否定回答:No, it isn't.

简单易懂的:
变疑问或否定式时。如果谓语中有be动词的某种形式(am, is, are,was, were)或情态动词(can,may,shall,must等)就把这些词提前可构成疑问;在这些词后直接加not构成否定。
he is a teacher --- he is not a teacher
--- Is he a teacher ?
he can swim ---- he can not swim.
---- Can he swim

而不包含以上那些词时,即实义动词做谓语时,就需要有助动词(do。does。did)来帮助完成

i get up early everyday --- Do you get up early everyday ?
----- i do not get up early everyday.

这里要注意两点,
1.一般现在时态当主语是第三人称单数时,动词用的是三单形式,即动词后加s或es。例如
he gets up early everyday.
变成否定或疑问时要用助动词does。does是do 的第三人称单数形式,已经体现了三单,所以实义动词要还原为动词原形:
he does not get up early
Does he get up early ?
2.同样的道理,当是一般过去式时,要用助动词did。did为do/does的过去式,已经体现了过去时态,所以这时变否定或疑问实义动词需要还原为动词原形
he get up early everyday
he did not get up early
Did he get up early ?

第一题:
一般疑问:was

(把be动词was提到句首即可。)

in.
(be动词was后加否定式
not
即可)
第二题:(hace

have
they

第三题:shall
