特殊句式讲解

特殊句式1.so +助动词/be动词/情态动词+主语 So do I. 我也是。

neither +助动词/be动词/情态动词+主语 Neither do I. 我也不是。

①这两种结构常用来说明前面所说的情况也同样适用于后面的人或物，意思是“某人〔物〕也是这样〞。

这种结构中的助动词/be动词/情态动词在形式上与前句的谓语动词保持一致，而其单复数形式那么由后句的主语决定。

Lucy is a good student, and so is Lily.Lucy是好学生，Lily也是(好学生)。

I missed my father and mother, so did my sister.我想我爸爸和妈妈，我的姐姐也想(他们)。

Jim works hard on his Chinese, and so does Lucy.Jim努力学习汉语，Lucy也是。

②这两种结构的不同点是：“so+助动词/be动词/情态动词+主语〞依附于肯定句，表示前面的肯定情况也适合后面的人或物，意为“某人/某物也……〞，相当于“sb/sth do, too〞。

“neither+助动词+主语〞依附于否认句，表示前面的否认情况也适合后面的人或物，意为“某人/某物也不……〞，相当于“sb/sthdon’t, either〞。

Mary didn’t watch TV last night, and neither did Jim.He likes skating and so do I.Me neither. 我也不。

I don’t like dancing, and neither does he.2.There be句型There be句型是表示“存在〞的一个句型，是一个主语在be动词后面的倒装句。

Is there a pay phone in the neighborhood?There is a tree in front of the building.There are 46 students in my class. 我们班有46位学生。

Ψ主语主语表示句子主要说明的人或事物，一般由名词，代词，数词，不定式等充当。

It is adj for sb to do 还是It is adj of sb to do

It is adj for sb to do还是It is adj ofsb to do一、例题分析：In China,it's impolite to use your chopsticks to hit an empty bowl.在该句中，It为形式主语,真正的主语是后面的动词不定式，该句结构为：It is+adj.+to do sth.意为"做某事是……的"。

有时在to do sth.前加上for或of sb.,表示动词不定式(短语)的逻辑主语。

如：It's difficult for me to work out this physics problem.it's very kind of you to help me.那么，It is+adj.for sb+to do sth.与It is+adj.of sb+to do sth.有何区别呢？It is+adj.for sb+to do sth.中的形容词通常为difficult, easy,hard,important,(im)possible,necessary等，这类形容词用来描述的是事物的特征。

而It is+adj.of sb+to do sth.中的形容词通常为kind,good, nice,polite,clever,careless,foolish等，这类形容词用来描述的是人的性格、品质特征。
