考点一 强调句
一、强调句
1.强调句的基本句型结构:It is/was+被强调部分+that/who+句子其他部分。该句型可对句子的主语、宾语、状语等进行强调。当强调部分是人,且作主语时,引导词也可用who。强调主语时要注意连接词与谓语的一致性。
It is our teacher who/that helps us make great progress.
是我们的老师帮助我们取得了巨大的进步。
2.强调句的一般疑问句结构:Is/Was+it+被强调部分+that/who+句子其他部分?
Was it in the park that he met our new teacher
他是在公园里遇到了我们的新老师吗?
3.强调句的特殊疑问句结构:疑问词+is/was+it+that/who+句子其他部分?
When was it that he made up his mind to take this course
他是什么时候决定上这门课的?
【点津】
由疑问词引导的强调结构作宾语从句时,从句必须使用陈述语序。
He asked me who it was that took his umbrella by mistake.
他问我是谁错拿了他的伞。
4.not ... until ...句型的强调结构:It is/was not until...that...。
It was not until twelve o'clock last night that I went to bed.
昨天晚上直到十二点我才去睡觉。
二、强调谓语动词
用助动词do,does或did来强调谓语动词,用于一般现在时和一般过去时的肯定陈述句中,do还可以用于祈使句。
The family did manage to send him to a technical school.
这家人确实设法把他送到了一所技术学校。
三、强调句与三大从句的区别
类型 区别
与主语 从句 强调句去掉It is/was和that 之后,句子结构仍然完整,而主语从句却不能。
It is there that accidents often happen.(强调句)
It is a fact that English is being accepted as an international language.(主语从句)
类型 区别
与定语 从句 强调句中that没有意义,且不作任何成分,而定语从句中that为关系代词,在从句中充当主语、宾语或表语。
It is novels that Miss William enjoys reading.(强调句)
It is a question that needs careful consideration.(定语从句)
类型 区别
与时间 状语从句 强调句去掉It is/was和that后,结构仍然完整,而It is ...when...中,it指代时间。
It was at six o'clock that I got up today.(强调句)
It was six o'clock when I got up today.(时间状语从句)

考点二 省略句
一、状语从句的省略
在时间、让步、方式、条件、地点等状语从句中,如果状语从句的主语与主句的主语一致或从句的主语是it,而且状语从句的谓语中有be动词,可以将从句中的主语连同be动词一起省略。
While (I was) walking the dog on the street the other day, I met one of my old friends.
前几天在街上遛狗的时候,我遇到了我的一位老朋友。
If (you are) asked to look after luggage for someone else, you should inform the police at once.
如果被要求替别人照看行李,你应该立即通知警察。
There are some health problems that, if/when (some health problems are) not treated in time, can become bigger ones later on.
有些健康问题,如果不及时治疗,以后会变得更严重。
二、动词不定式的省略
1.动词不定式作动词(expect, refuse, mean, like, love, prefer, wish, hope, want 等)的宾语或作一些动词(expect,want, tell,order等)的宾补时,常承前省略动词不定式后的内容,但保留动词不定式符号to。
John didn't pass his driving test, but I expected him to (pass his driving test).
约翰没有通过驾照考试,不过我希望他能通过。
2.当动词不定式在形容词(glad,happy,pleased,delighted, anxious等)后作状语时,to后的内容常承前省略。
—Would you like to come to the party
—I'm glad to (come to the party).
——你愿意来参加聚会吗?
——我很乐意去(参加聚会)。
【点津】
如果动词不定式中含有be,have,have been时,通常保留be,have,have been。
三、so/not构成替代省略
英语中还常常用so/not等来代替省略的肯定内容或否定内容,so/not多跟在以I'm afraid, I hope, I think, I guess, I believe等开头的答句中。
—Do you think it will rain
—I hope so/not.
——你认为会下雨吗?
——我希望下/不下。
四、常用的与if相关的省略结构
if ever如果曾经发生过的话
if busy如果忙的话
if possible如果有可能的话
if so如果这样的话
if not如果不这样的话
if necessary如果有必要的话

考点三 倒装句
一、部分倒装

这不是我的故事;也不是故事的全部。我的故事结局不同。

Strange as it may sound, if you're unsatisfied, the issue is not a lack of means to meet your desires but a lack of desires.
尽管这听起来很奇怪,但是如果你不满意,问题不是缺少满足你愿望的方法,而是你根本就没有愿望。
二、完全倒装
1.here, there, now, then, out, in, up, down, away, on the wall, in the room 等表示地点、时间或方位的副词或介词短语置于句首,且句子主语是名词时,句子用完全倒装。如果主语是人称代词,则不用倒装语序。
By the window sat a young man with a magazine in his hand.
一位年轻人坐在窗边,手里拿着一本杂志。
2.有时为平衡句子结构或突出强调,将作表语的介词短语、形容词、副词或分词提到句首,构成“表语+系动词+主语”的完全倒装结构。

过马路时你一定要小心。
三、附加疑问句
附加疑问句,又称反意疑问句,由“陈述部分+附加疑问部分”构成,若陈述部分为肯定式,则附加疑问部分为否定式,反之亦然。
1.陈述部分含有must的附加疑问句
(1)当must作“必须”讲时,其附加疑问句的动词用needn't; 当mustn't作“不允许,禁止”讲时,其附加疑问句的动词用must。
You must go now, needn't you
你现在必须走,不是吗?
You mustn't smoke here, must you
你不能在这里吸烟,是吧?
(2)当must表示推测,作“一定,准是”讲时,附加疑问部分的动词形式要根据must后面的动词所表示的时间来确定。

他说她会准时来这里,不是吗?
【点津】
当主句是I think/believe/suppose等结构时,附加疑问部分往往根据宾语从句的主语和谓语而定,需特别注意否定转移现象中的肯定式和否定式。
