1.高二年级下册英语必修二备考知识点
用法较复杂，以下几点需引起注意：1. 表示“从事”或“正在做”，其后接的名词通常不用冠词。如：
at cards 在玩牌 at work 在工作
at war 在交战 at lunch 在吃中饭
at table 在吃饭 at school 在上课
但也有少数搭配习惯上要用冠词。如：
at the desk 在读书 at the telephone 在打电话
2. 通常表示地点、场所、活动等，通常用汉语的“在”翻译，但有时它可以表示起点，相当于汉语“从”。如：
Everybody, we begin at page 50 today. 各位，我们今天从第50页开始。
3. at 可以与“人名+’s”连用，指其家或工作处。如：
We had lunch at Bill’s. 我们在比尔家吃了午饭。
I spent the weekend at my grandmother’s. 周末我是在奶奶家度过的。
I bought some rolls at the baker’s. 我在面包店里买些圆面包。
4. 表示地点时，比较它与介词 in 的相同和不同之处：有时若不严格区别，两者可以换用。如：
The meeting was held at [in] the hotel. 会议在宾馆举行。
但是，如果我们想到的是位置，一般用 at;如果想到的是空间，一般用in。如：
Let’s meet at the station. 我们在车站见吧。
Nobody was in the classroom. 教室里没有一个人。
两者的另一个区别是：较大的地方用in，较小的地方用 at。如：
in London 在伦敦 in the world 在世界上
at the airport在机场 at the door 在门口
但大小是相对而言的，有时随着说话者的着眼点不同，大地方也可能用at(即将其视为一个点)。如：
Our plane refueled at London. 我们的飞机在伦敦加油。
5. 表示目的或目标，在某些搭配中，at 往往含有主观上的不友好意味或恶意;相同情况下，若将at改为to，意思则大不一样。比较：
The dog came at me. 狗向我扑来。(意即咬人)
The dog came to me. 狗向我走过来。(无咬人之意)
He threw the ball at me. 他把球向我砸来。(意欲打人)
He threw the ball to me. 他把球抛给我。(无打人之意)
He shouted at me. 他对我吼叫。(意在训人)
He shouted to me. 他朝着我大声喊。(无训人之意)
表示目标时，at 只表示行为本身，并不表示行为的结果。比较：
He shot at the bird, but missed. 他向鸟射击，但未射中。
He shot the bird. 他射中了那只鸟。

3.高二年级下册英语必修二备考知识点
介词 against 用法介绍。1. 注意以下两个基本用法，许多其他用法和搭配均可从这两种基础引申出来：
(1) 表示“反对”“对着”“违反”“不利于”等。如：
We are all against his idea. 我们都反对他的想法。
He was married against his will. 他结婚是有违本意的。
He spoke against the new law. 他发言抨击新法律。
There were 20 votes for him and 12 against him. 有20票赞成他，12票反对他。
(2) 表示“靠着”“顶着”“迎着”“衬着”等。如：
He stood with his back against the door. 他背靠门站着。
He hit his head against the window. 他的头撞到了窗户上。
It is difficult to see anything against this bright light. 对着这种强光很难看到任何东西。
Bright red flags flow in the wind against the blue sky. 鲜艳的红旗映着蓝天迎风飘扬。
2. 注意 against 是介词，不是动词。如：
他靠在树上。
正：He leaned against the tree.
误：He against the tree.
这个计划你是赞成还是反对呢?
正：Are you for or against the plan?
误：Do you support or against the plan?
3. 正因为against是介词，所以后接动词时要用动名词。如：
我反对在警察到达之前采取任何行动。
正：I’m against doing anything till the police arrive.
误：I’m against to do anything till the police arrive.
4.高二年级下册英语必修二备考知识点
1. 表示“在……期间”，是介词，不要将其误用作连词。如：他在巴黎期间，与他的朋友住在一起。
误：During he was in Paris, he lived with his friends.
正：While he was in Paris, he lived with his friends.
正：During his stay in Paris, he lived with his friends.
2. during 和 for 均可表示一段时间，但两者有差别。
(1) during 通常表示事件发生在何时(when)，而for则表示事件持续了多长时间(how long)。如：
He was in hospital for six weeks during the summer. 他在夏天住了 6 个星期的医院。
(2) 两者之后均可接由 the whole 引起的时间短语，但通常不能接由 all 引起的时间短语。如：
他整个夏天都住在那儿。
正：He stayed there for [during] the whole summer.
误：He stayed there for [during] all the summer.
(3) 在“数词+时间名词”之前以及在some time, a long time之类表示泛指一段时间的词组之前，可用介词 for，但不用 during。如：
He lived here for ten years (for some time). 他在这儿住过 10 年(一段时间)。
2. during与in均可表示“时间点”，有时可互换。如：
I’ll be on holiday in [during] August. 我将在8月度假。
He woke up three times in [during] the night. 夜里他醒了 3 次。
但在使用时还有以下几点要注意：
(1) 比较而言，during 更强调时间的延续，in 只是指一般性的某一时间。因此若表示状态或习惯性动作，多用during，否则以用in为常见。如：
Many people suffered hardship during the war. 许多人在战争期间受苦遭难。
He was injured in the war. 他在战争期间受了伤。
(2) 在stay, visit, meal等表示行为要持续一段时间的名词之前，只能用during 而不能用in。如：
The phone rang during the meal. 吃饭时电话铃响了
I went to see my aunt during my stay in Beijing. 在北京逗留期间，我去看了我的姑妈。
(3) 与季节名词连用，in表泛指，during表特指。如：
In summer we often camp in the forest. 夏天我们常在森林里露营。(泛指)
During the summer we camped in the forest. 今年夏天我们在森林里露营。(特指)

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。
4. 倒装句的基本用法
a) 构成疑问句(除对主语或主语之定语提问的特殊疑问句外)：
When are we going to drink to your happiness? 我们什么时候喝你们的喜酒?
Have you seen the film? 你看了那部电影吗?
b) 在以here, there, now, then, in, away, up down等副词开头的句子中:
Away went the crowd one by one. 人们一个一个地离去。
Here comes our teacher! 我们的老师来了!
c) 副词only+状语放在句首时:
Only then did he realize his mistakes . 只有在那时他才认识到自己的错误。
Only in this way can you learn maths well . 只有用这种方法你才能学好数学。
d) 含有否定意义的副词或连词(如little, hardly, never, rarely, no sooner…than等)放在句首时:
Little did I think that he could be back alive. 我没有想到他竟能活着回来。
Not until New Year’s Day shall I give you a gift. 我要到元旦那天才能给你礼物。
Hardly had the train arrived at the station when we ran towards the sleeping car looking for our guests.
火车刚一进站，我们就跑到卧车那儿去找我们的客人。
e) 副词so或 neither(nor)在句首:
He is interested in pop-songs, and so am I.他对流行歌曲感兴趣，我也如此。
He hasn’t been to the countryside, neither does he want to go there.他没有去过农村，他也不想去那里。
f) 在方式状语thus开头的句子中及程度状语so放句首:
Thus ended his life. 这样结束了他的生命。
So loudly did he speak that even people in the next room could hear him . 他讲话的声音那样大，连隔壁屋子里的人都听得见。
2. so作“也”讲时，引导的句子用倒装语序，例如：
He went to the film last night. So did I. 他昨天晚上去看电影了，我也去了。
如不作“也”讲而只起连词作用，表示一种结果的意思，句子就要用正常语序。例如：
His mother told him to go to the film. So he did. 他母亲叫他去看电影，他就去了。
“He is a tall thin man.” “So he is.” “他又高又瘦。” “确实如此。”
3. 某些让步状语从句往往把表语提到主语前面或放在句首，以构成倒装结构。例如：
No matter how interesting the book is，he doesn't like to read it.不管这本书多有趣，他都不想看。
However hard a solid may be，we can change its shape. 不管一个固体有多硬，我们都可以改变其形状。
Young as he is, he knows a lot. 虽然他年轻，却知道很多东西。
4. 在虚拟语气中，如果非真实条件句省略if，须将主句中的were, had和should等助动词和主语颠倒形成部分倒装。例如：
Were he younger (= If he were younger), he would learn skating. 假如他年轻一些，他就会去学溜冰。
Should they forget (= If they should forget) to bring a map with them, they would get lost in the woods
如果他们忘记带一张地图的话，他们就会在深林里迷路。
Had they realized (= If they had realized) how important the task was, they wouldn’t have refused to
accept it. 假如他们认识到这个任务是多么重要的话，他们就不致于拒绝接受这项任务。
