(一) 陈 述 句
1. 陈述句的功能及结构特征
陈述句是用来说明一个事实的句子,其主要功能是传递信息、提供情况,用来肯定或否定某个事物、某件事或某种情况。陈述句的结构特征通常是主语在前,谓语在后,读时用降调,句尾用句号。如:
My mother is going to buy me a new dress.
我妈妈打算给我买一条新的连衣裙。
2. 陈述句的肯定句变为否定句

She is an English teacher.
→ She is not an English teacher.
You can park your car here.
→ You cannot park your car here.
(2) 句中无be动词或情态动词时,在谓语动词前加助动词don't, doesn't 或didn't,原来的动词要用原形。如:
Mike gets up early every morning.
→ Mike doesn't get up early every morning.

is not=isn't are not=aren't
was not=wasn't were not=weren't
cannot=can't could not=couldn't
do not=don't does not=doesn't
did not=didn‘t will not=won't
