（外研版）初中英语七年级下册知识点归纳总结(12)

④can可用于表示可能性，推测，允许等情况，而be able to通常不这样用。
3. not…any more = no more 不再......，侧重程度和数量
eg：
You can drink no more. = You can"t drink any more. 你不能再喝了
not any longer = no longer侧重时间
eg：
He no longer lives here. = He doesn"t live here any longer. 他不住在这里了。
三、句型
1.there won’t be = there will not be
there be结构的一般将来时的否定形式，肯定结构为: there will be.
there be结构的将来时结构也可以用there is going to be 或there are going to be.
eg：
There will be a football match on TV tomorrow. = There is going to be a football match on TV
tomorrow. 明天会有一场电视球赛。
2.句型结构: it is adj. to do sth.
it是形式主语，真正的主语为动词不定式后置。
eg: It was wrong for you not to help her. 你当时不帮助她是错误的。(it代替不定式短语）
3. not only…but also… 用于连接两个表示并列关系的成分，着重强调后者，其意为“不仅……而且…”
eg: She not only plays well, but also writes music.
注意：若连接两个成分作主语，其谓语通常与靠近的主语保持一致。
eg：
Not only you but also he has to leave. 不只是你，他也得离开。
若连接两个句子，not only后面的句子要用倒装。
eg：
Not only did he speak more correctly, but he spoke more easily.
