正：Are you for or against the plan?

误：Do you support or against the plan?

正：I’m against doing anything till the police arrive.

误：I’m against to do anything till the police arrive.

高二英语必背知识点总结

系动词

系动词亦称联系动词(Link Verb)，作为系动词，它本身有词义，但不能单独用作谓语，后边必须跟表语(亦称补语)，构成系表结构说明主语的状况、性质、特征等情况。说明：有些系动词又是实义动词，该动词表达实义时，有词义，可单独作谓语。例如：

He fell ill yesterday.　 他昨天病了。(fell是系动词，后跟补足语，说明主语情况。)

He fell off the ladder.　 他从梯子上摔下来。fell是实义动词，单独作谓语。

1)状态系动词

用来表示主语状态，只有be一词。例如：

He is a teacher.　他是一名教师。(is与补足语一起说明主语的身份。)

2)持续系动词

用来表示主语继续或保持一种状况或态度，主要有keep, rest, remain, stay, lie, stand。例如：

He always kept silent at meeting.　 他开会时总保持沉默。

This matter rests a mystery.　 此事仍是一个谜。

1.倒装句的定义：英语最基本的词序是主语在谓语动词的前面。

如果把谓语动词放在主语前面，就叫做倒装。

2. 倒装句的构成

a) 完全倒装

将句子的主语和谓语完全颠倒过来，称之为完全倒装。

Are you from here? 你是本地人吗?

Now comes the chance. 机会来了。

b) 部分倒装

只将助动词、系动词或情态动词移至主语之前，谓语的其他部分仍保留在主语的后面，称之为部分倒装。例如：

Has he come? 他来了吗?

Seldom have we felt as comfortable as here. 我们难得像在这里这么舒服。

Only in this way can we do the work better.

只有这样我们才能把工作做得更好。

3. 倒装的原因

a) 句子语法结构的需要。例如：

Did you attend the meeting? 你参加会议了吗?

Long live peace! 和平万岁!

b) 一些句型的固定用法。例如：

Such were his last words. 他最后的话就是这样。

c)强调的需要。倒装以后，句子更加流畅生动。例如：

Never before have we seen such a sight. 以前我们从来没有见过这样的情景。

Before us lay a lot of difficulties. 在我们前面有很多困难。

Often did we warn them not to do so. 我们曾多次警告他们不要这样做。
