高考英语必考知识点
1语态和时态
— Do you see those people on the little sandy island?
— Yes, they _______ handkerchiefs for the last half hour. I wonder why.
A. were waving B. waved
C. had waved D. have been waving
【正确答案】D
【高考考点】考查现在完成进行时。
【详细解析】这个挥手帕的动作是在半小时前开始的，然后一直在挥，一直挥到了说话的这个时候，所以我们用现在完成进行时强调一个动作的持续。A选项为过去进行时，B选项为一般过去时，C选项为过去完成时，这三个时态都是和过去有关，和现在无关。题干中出现last或者是last half hour，recent等这类词的话，我们一般都会选择现在完成进行时。故本题正确答案是D。
2名词性从句
The information could be helpful to ____ will take over the job.
A. those B. who
C. whoever D. anyone
【正确答案】C
【高考考点】考查名词性从句。
【详细解析】名词性从句包括主语从句、表语从句、宾语从句和同位语从句。此题考的就是介词to后的宾语从句，whoever在从句中作主语。A、D两个选项需要在后面加上who;B选项是who在名词性从句中表示疑问，e.g. Who will take over the job has not been decided yet. 故本题正确答案是C。
3虚拟语气和情态动词
— David, we went to Lake Geneva for the weekend.
— That _______ a very nice change. I wish I had gone there.
A. must be B. must have been
C. could be D. could have been
【正确答案】B
【高考考点】考查情态动词。
【详细解析】must表推测，“肯定……”，must be表示对现在和将来事实的推测;must have been表示对过去事实的推测。这里表示一个肯定的推测，又因为是上个周末的事情，说明这件事情已经发生了，故选B;C选项could“可能”，表示轻微的怀疑或委婉的陈述看法，e.g. His story could be true, but I hardly think it is.他所说的这个故事可能是真的，但是我基本上不相信;D选项could have done是虚拟语气，表示“过去本能够做某事却未做”，e.g. You could have done better, but you didn’t try your best.你原本是可以做的更好的，但是你并没有尽自己最大的努力。
4代词
Knowledge begins to increase as soon as one individual communicates his ideas to _______ by means of speech.
A. other B. another
C. the other D. an other
【正确答案】B
【高考考点】考查代词。
【详细解析】other用作代词时，意为“另一个;其他的人(东西)”，不单独使用：the other，the others，others;another用作代词时，表示没有具体所指的“另外一个”。e.g. One person may like fishing, while another may prefer hunting.一个人可能是喜欢钓鱼，而另一个可能喜欢打猎;the other表示“两者中的另一个”，表示特指;D选项没有这种用法。故本题正确答案是B。
5非谓语动词
Almost everyone of the graduates wants to deliver the keynote speech at the graduation ceremony. For the speaker, _______ is an honour.
A. invited B. being invited
C. be invited D. inviting
【正确答案】B
【高考考点】考查非谓语动词。
【详细解析】A选项invited是过去分词不能充当主语;C选项be invited不是非谓语形式;D选项语态错误，应该用被动。故本题正确答案是B。遇到动词要考虑四点：① 先判断是谓语还是非谓语;② 主语;③ 主语和非谓语动词的主/被动关系;④ 非谓语动词与谓语动词的时间关系。e.g. Being exposed to the sun for too much time will do harm to one’s skin.在太阳下暴露太久对皮肤有害。e.g. The girl’s being educated in a good environment is what her parents have expected.这个女孩在一个良好的环境中受到教育是她父母所期望的。
6定语从句
Today’s college is appropriate as a setting for a society _____ its members must acquire and manage knowledge from a wide variety of sources.
A. which B. so that
C. where D. of which
【正确答案】C
【高考考点】考查定语从句。
【详细解析】本题考查关系副词where引导的定语从句，修饰先行词college，where在定语从句中作地点状语。A选项which是一个关系代词，只能充当主语或宾语;B选项so that“为了……”，引导目的状语从句，在这里逻辑不对;D选项of which是“介词+关系代词”结构，先行词college放到定语从句中，应该是说“in the college”，所以这个介词应该用in。故正确答案为C。
7动词
When problems such as energy crisis, pollution and population explosion _____, people are asked to share the bitterness and endure the hardship.
A. are arisen B. arise
C. arising D. arisen
【正确答案】B
【高考考点】考查动词。
【详细解析】从题干可知when引导的时间状语从句中缺少谓语动词，故排除C、D两项;arise“出现、发生”，是不及物动词，无被动语态。故正确答案为B。
8状语从句
They didn’t want to admit to any shortage of food _____ it might reveal a weakness to be exploited by their enemies.
A. in order that B. or else
C. but for D. for fear that
【正确答案】D
【高考考点】考查状语从句的连词。
【详细解析】A项in order that引导目的状语从句;B项or else“否则”在此处用句意不通;C项but for表示“如果没有，要不是”，它往往用在虚拟语气中;D项for fear that也引导目的状语从句，但它表示“生怕某种不好的事会发生”。e.g. Shut the window for fear that it may rain.把窗关起来，以防下雨。根据句意可知，他们不愿意承认食物短缺，是因为他们害怕被敌人知道，然后利用他们的.这个缺点。故正确答案为D。
9固定搭配
Without solutions _____ the gap between the rich and the poor, there can be no “harmonious society”.
A. of B. for
C. to D. on
【正确答案】C
【高考考点】介词的用法。
【详细解析】solution to…“解决……的方法”，为固定搭配，故正确答案为C。接下来我们就来看一下还有哪些名词后面跟介词to。
【access】have access to有通道/有使用/有见到(某人/某物的机会或权利)
【answer】answer to对……的回答
【approach】approach to sth./ approach to doing sth.做某件事情的方法
【attitude】attitude to sth.对待……的态度

【damage】do damage to sth.对……造成损坏、破坏
【devotion】devotion to sth.对……的奉献
【entrance】entrance to某地方的一个入口
【introduction】introduction to sth.对……的介绍
【limit】the limit to sth.对……的一个限度/限制
【objection】the objection to对……的反对
【reaction】reaction to sth.对……东西的反应
【response】response to sb./sth.对……人(或物)的回答/回复
10主谓一致
— _____ five hundred dollars a big sum to a Chinese family?
— I’m afraid not.
A. Is B. Are C. Were D. Will be
【正确答案】A
【高考考点】主谓一致。
【详细解析】表示金钱、价格、时间、长度等复数名词、词组作主语时，一般被看作是一个整体，谓语动词常用单数形式;另外题中说到a big sum“一大笔钱”，说明它把500美金这个复数的概念是当作一个整体去理解的，这也给了我们启示。故正确答案为A。
高考英语重要知识点
语法知识归纳
1.全部倒装
就是将句子中的谓语动词全部置于主语之前。全部倒装通常用于：
(1)here, there, now, then, thus等副词置于句首时
Then came the chairman.那时总裁来了。
Here is your letter.你的信。
(2)表示运动方向的副词或地点状语置于句首时
Out rushed a missile from under the bomber.轰炸机肚底下窜出一枚导弹。
Ahead sat an old woman.前面坐着一个老妪。
注意：
①主语必须是名词，而不能是代词。
②谓语动词通常是be, come, go, lie, run等表示来去或状态的动词。
③谓语动词的时态通常是一般现在时和一般过去时。
2.部分倒装
就是指将谓语的一部分如助动词、情态动动词或be移到主语前。如果句子的谓语中没有这类词，则在主语前加助动词do, does或did，谓语动词用原形。部分倒装用于：
(1)否定或半否定的词语，如no, not, never, seldom, little, hardly, at no time, in no way, not until…等位于句首时。
Never have I seen such a performance.从未见过如此糟糕的表演。
Nowhere will you find the answer to this question.无论如何你不会找到这个问题的答案的。
Hardly had she gone out when a student came to visit her.她刚出门，就有个学生来访。
No sooner had she gone out than a student came to visit her.她刚出门，就有个学生来访。 Not until the child fell asleep did the mother leave the room.母亲一直到孩子入睡后离开房间。
注意：①hardly…when…, no sooner…than…或not only….but also…中，都是前一句倒装，后句不倒;②not until…后接时间状语从句时，从句不倒，主句倒。
真题：(1)Not until I began to work______ how much time I had waited. (全国)
A didn’t I realize B did I realize C I didn’t realize D I realized
解析：not until…位于句首，主句主谓要用部分倒装，排除C和D;not until句型中不再用否定，故选B。
(3)so, neither, nor表示“也”或“也不”时
Tom can speak French. So can Jack.汤姆会讲法语，杰克也会。
If you go to the park tomorrow, so will I.如果你明天去公园，我也去。
He hasn’t gone there. Neither /Nor have you.他没有去那里，你也没去。
注意：当so引出的句子是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”。如：
Tom asked me to go to play football and so I did.汤姆邀我去踢球，我去了。
—It’s raining hard.雨下得真大。
—So it is.是呀。
(3)“only+状语”位于句首时

Only then did I realize that I was wrong.只有到那时我才意识到我错了。
Only when he is seriously ill does he ever stay in bed.病得狠重时，他才卧床休息。
注意：如果句子为主从复合句，则主句倒装，从句不倒装。
(4)as引导让步从句时
必须将表语或状语提前(形容词,副词,分词,实义动词提前)。但需注意：
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。
Try hard as he will, he never seems able to do the work satisfactorily.他工作很努力，但总不能让人满意。
Child as he is, he knows a lot.他虽然是个孩子，但很懂事了。
(5)其他部分倒装
①so…that…句型中的so +adj. /adv.位于句首时。
So frightened was he that he did not dare to move an inch.他害怕得很，动也不敢动。
真题：So difficult ______ it to live in an English speaking country that I determined to learn English well.
A. I have felt B. have I felt C. I did feel D. did I feel
解析：so + adj.放在句首，用部分倒装，排除A和C;由determined可知用过去式，故选D。
②在某些表示祝愿的句型中。
May you all be happy.愿你们都快乐。
③在虚拟条件句中有were, had, should等词时，可将if省略，把were, had, should移到主语之前。
Were I you(=If I were you), I would try it again.我是你的话，就再试一次。

1.简单谓语：由一个动词或动词短语构成。如：He practices running every morning.
2.复合谓语：(1)由情态动词或其他助动词加动词原形构成。如：You may keep the book for two weeks. He has caughta bad cold. (2)由系动词加表语构成。如：We are students.
在英语中一个简单句只能有一个谓语动词(知道为什么吗)，而且，我们平时学习的时态是针对谓语动词来说。如果以do为例，do, did ,have done, will do, had done, is/am/are doing, was/were doing, would do。在简单句中，谓语动词和主语是句子的核心，是不可以随意删掉的。

一、不定式做主语：
1、不定式做主语一般表示具体的某次动作。动名词doing表示习惯的，经常的动作。
e.g:Tofinishthebuildinginamonthisdifficult.
Todosuchthingsisfoolish.
Toseeistobelieve.(对等)
注:1).不定式作主语时,谓语用单数
2).当主语较长，谓语较短时，常用it做形式主语，而将不定式放到谓语的后面。
it做形式主语，不定式放在谓语动词之后常用于下列结构中：
(1)Itis/was+adj.+ofsb.todo…
(2)Itis+adj.+forsb.+todo…
Itiseasy/difficult/hard/foolish/unwise/right/wrong/unnecessary
(3)itis+a+名词+todo...
Itisapity/apleasure/apleasantthing/one’sduty/anhonor/ashame/acrime/noeasyjob…todo
Ittakes(sb.)sometime/courage/patience…todo…
Itrequirescourage/patience/hardwork…todo…
注意:probable和possible均可作表语，但possible可以用不定式作真实主语，而probable不能用不定式作真实主语。
Itisprobableforhimtocometothemeeting.(错)
Itispossibleforhimtocometothemeeting.
Itispossible/probablethathewillcometothemeeting.
