语法，作为英语学习的重点和基本功，也必然成为备考英语的重中之重。接下来是小编为大家整理的高考英语必考重点知识，希望大家喜欢!
高考英语必考重点知识一
plenty的用法
1.plenty指某物(特别是生存所需物品)已经足够了，即“充裕，大量，富庶”，间或含有过量或感谢的意味，通常是用在好的方面，且只能用于肯定句中。
2.plenty可指复数的事物，他还代表充分、非常。富足的等意思。
3.plenty常用于plenty of短语，表示“充足的相当多的”通常只用于肯定句，其后可接可数名词，也可接不可数名词。plenty of作主语时谓语动词要跟of后名词的数一致。
4.in plenty意为“大量的”，在句中可作表语、定语或状语。
5.plenty通常用在好的方面，所以一般认为plenty of troubles许多麻烦);plenty of difficulties(许多困难)等是不合英语习惯的。但近年来plenty of errors，plenty of troubles等说法似乎逐渐多了起来。
6.plenty用作副词时是非正式用法，意思是“相当地，充分地”，多用来修饰形容词，且其后可跟enough搭配使用。

倒装结构
一 全部倒装
全部倒装是指将句子中的谓语动词全部置于主语之前。此结构通常只用与一般现在时和一般过去时。常见的结构有：
1. here, there, now, then, thus等副词置于句首, 谓语动词常用be, come, go, lie, run。例如：
1) There goes the bell. 铃声渐渐消失了。
2) Then came the chairman. 然后主席就来了
3) Here is your letter. 这是你的信。
2. 表示运动方向的副词或地点状语置于句首，谓语表示运动的动词。例如：
1) Out rushed a missile from under the bomber. 轰炸机下面发出了一颗导弹。
2) Ahead sat an old woman.
注意：上述全部倒装的句型结构的主语必须是名词，如果主语是人称代词则不能完全倒装。例如：
1) Here he comes. 他来了。
2) Away they went. 他们走了。
二 部分倒装
部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词，则需添加助动词do, does或did，并将其置于主语之前。
1. 句首为否定或半否定的词语，如no, not, never, seldom, little, hardly, at no time, in no way, not until? 等。例如：
1) Never have I seen such a performance. 我从来没看过这样的表演。
2) Nowhere will you find the answer to this question. 你在哪儿都不会找到这个问题的答案。
3) Not until the child fell asleep did the mother leave the room. 妈妈直到孩子睡着才离开房间。
注意：当Not until引出主从复合句，主句倒装，从句不倒装。
注意： 如否定词不在句首不倒装。例如：
1) I have never seen such a performance.我从来没看过这样的表演。
2) The mother didn't leave the room until the child fell asleep.妈妈直到孩子睡着才离开房间。
2. 带有否定意义的词放在句首，语序需要部分倒装。常见的词语有： not , never , seldom , scarcely , barely , little , at no time , not only , not once , under on condition , hardly ? when , no sooner ?than ?等。例如：
1) Not only did he refuse the gift, he also severely criticized the sender. 他不仅拒收了礼品，还狠狠批评了送礼的人。
2) Hardly had she gone out when a student came to visit her. 她刚要出门时有个学生来找她。
3) No sooner had she gone out than a student came to visit her. 她刚要走时一个学生来看她。
注意：只有当Not only? but also连接两个分句时，才在第一个分句用倒装结构。如果置于句首的Not only? but also仅连接两个并列词语，不可用倒装结构。例如：
Not only you but also I am fond of music. 我和你都喜欢音乐。
3. 表示"也"、"也不" 的so, neither, nor放在句首时，句子作部分倒装。例如：
1) Tom can speak French. So can Jack. Tom能说法语，我也能。
2) If you won't go, neither will I. 如果你不去，我也不去。
注意： 当so引出的句子用以对上文内容加以证实或肯定时，不可用倒装结构。意为"的确如此"。例如：
1) Tom asked me to go to play football and so I did. Tom让我去踢足球，我去了。
2) ---It's raining hard. ---So it is. ---雨下得很大。 ---的确很大。
4. only放在句首，强调状语(副词，介词短语或状语从句等)，全句语序要部分倒装。例如：
Only in this way, can you learn English well.你只有用这种方法才能学好英语。
Only after being asked three times did he come to the meeting. 他被请了三次才来开会。 注意：如果句子为主从复合句，则主句倒装，从句不倒装
Only when he is seriously ill, does he ever stay in bed. 他只有病得非常严重时才会卧床休息。
三 as, though 引导的倒装句
as / though引导的让步从句必须将表语或状语提前 (形容词, 副词, 分词, 实义动词提前)。此时应注意：1) 句首名词不能带任何冠词;2) 句首是实义动词, 其他助动词放在主语后。如果实义动词有宾语和状语,随实义动词一起放在主语之前。例如：
Try hard as he will, he never seems able to do the work satisfactorily. 尽管他愿意努力工作，但是他好像从来都不能令他的工作満意。
注意: 让步状语从句中，有though，although时，后面的主句不能有but，但是 though 和yet可连用。
四 其他部分倒装
1. so? that 句型中的so 位于句首时，需倒装。例如：
So frightened was he that he did not dare to move an inch. 他害怕得动都不敢动。
2. 在某些表示祝愿的句型中，例如：
May you all be happy. 望大家开心愉快。
3. 在虚拟语气条件句中从句谓语动词有were, had, should等词，可将if 省略，把 were, had, should 移到主语之前，采取部分倒装。例如：
Were I you, I would try it again. 如果我是你，我就再试一次。
