二、考点精析与拓展
1.Something may have happened to her. She might have had an accident.
两句中都用的“情态动词may/might +完成时”的结构，有以下用法：
①may/might + have + 过去分词表示推测过去某动作“可能”发生了。如：
I can’t find my sunglasses, I may/might have left them at the
restaurant yesterday.
一般来说，may和might两者意思上没什么区别，只是may比might表示的可能性大些。如：
He may have heard of it from Jack.
He might have heard of it from Jack.
在下列情况下，may和might 用法有区别：
句子的主要动词是现在时，间接引语中用may/might;
句子的主要动词是过去时，间接引语中只用might.如：
He says that she may/might have misunderstood him.
He said that she might have misunderstood him.
②might + have + 过去分词，表示对本来可能发生而实际并未发生的动作的感叹或遗憾含有“责备”、“抱怨”之意，而may + 完成时无此含义。如：
You might have told us earlier.
This medicine might have cured your cough
2.must + have + 过去分词
表示推测过去某动作“一定发生了”。如：
-They quarrelled quite often and whenever they quarrelled they threw glasscup at each other.
-They must have broken a lot of glasses.
3.fall over意为“跌倒”，“跌跤”。如：
When he was skating, he fell over some times.
4.It was in Greece that Olympic competitions started.
这是强调句型，其结构为：It be + 被强调部分+that-clause.该句型可以对一个句子里的主语、宾语、状语（介短或从句）进行强调。
5.n.+ being performed in China.
该结构中being performed 是动记号-ing形式的被动语态，在一句子中用在名词之后，作定语。它常可改写成一个定语从句。如：
The prices of the TV sets being shown(= which are shown)are still unknown.
6.prepare sb.for…
该短语意为“使某人对……进行准备”。如：
Mother is preparing me for my journey.
prepare 作为动词，既是及物动词，又是不及物动词且常与for连用。如：
Mother asked my sister to prepare lunch.
7.preform exercises to music.
短语意为“伴随音乐做体操”，从中可知“do sth. to music”判决书为“伴随音乐做某事”。如：
She likes dancing to music.
她喜欢随着音乐跳舞。
8.There are safety measures to follow while training.
该句意为“训练时必须遵守安全措施”，这句话里应注意两点：
①while training 是从属连词与分词连用，在句子中做时间状语。结构“when/while + -ing 或过去分词短语”的使用条件是：
when/while 从句中的主语与主句中的主语相同。如：
You should have dropped in on me when staying here.
除了when/while 外，其他的从属连词如if，as if, though, as
before,after等，也有这样的用法。如：
If heated, ice can be turned into water.
②to follow 是不定式做定语，修饰名词measures,是主动表被动。在There be 句型中，用不定式做的定语时，即就是不定式与所修饰的名词之间是动宾关系，也常用不定式的主动语态形式。如：
There is a lot of work to do.
9.think to oneself
该动宾词组意为“心里想”。如：
She was thinking to herself how cold the room was.
Think aloud意为“自言自语”（=talk to oneself）。如：
He stood there with his lips moving as if he talked to
himself/thought aloud.
10.the moment主语 +Ｖ。
此结构中，the moment 用作连词，引导一时间状语从句，意为“一……就……”（=as soon as）。相同意思和用法的表达形式还有：the minute, the instant 和the second。如：
Telephone me the moment you get the results.
11.break off
该短语动词的意思是“中断说话”，“暂时停止”。如：
He broke off in the middle of a sentence.
break sth.off/break off sth. with sb.
前者意为“（使）折断”，后者意为“与某人突然断绝（关系）”。如：
The mast broke off /was broken off when the ship was moving.
12.be busy doing sth.
该结构意为“忙于做某事”。应注意的是be busy 后只能接动词-ing形式，不能接动词不定式to do,相同结构的形容词还有worth。如：
①He is busy writing his composition.
②She keeps busy working on a new novel these weeks.
③This book is well worth seeing.
13.The first thing she did was go up to her trainer…and thank her…
该句中，go up to…是动词不定式短语作表语，省略了不定式符号to,这是因为主句的主语被定语从句she did修饰的缘故。语法规定，解释doing 精确意思的分句，可用不带to 的动词不定式。如：
What I can do is (to)help him (to)clean the floor.
14.at the doctor’s
该结构为介词+名词所有格，意为“在诊所”。所有格-’s后一般接名词，如her mother’s bike ,但有时这个名词可省略，主要表现在以下两个方面：
①指一个企业，机构，教堂，学校，医院，家庭，理发店，店铺时。如：
She is at the hairdresser’s.
②为了避免重复，省略-’s后的名词。如：
I have read some of Shaw’s plays,but none of Shakespeare’s.
15.knock into
该短语意为“把……敲人” ，也可意译为“撞着某人/某物”如：
①The wall is so hard I can’t knock nails into it.
②He was reading while he eas walking and knocked into a tree.
16.it looks as if…
意为“看起来好像……”，as if可用as though替换，在此引导表语从句，另外它们也可引导状语从句，从句既可用陈述语气，也可用虚拟语气。如：
①It looks as if /though it’s going to rain.（陈述语气）
②You look as if you’d seen a ghost.（虚拟语气）
17. It’s (just)like sb. to do sth.
该句意思是“某人（恰恰）就是……这个样子”，表示赞扬或不满；若用否定式，则表示怀疑。如：
It is just like her to think of others before thinking of herself.
18.in a flash
该介宾词组意为“转眼间”，“突然间”，“瞬间。”如：
In a flash. I realized where we had met before.
19.on one’s arrival…
该词组意为“一到达……就……”（= on arriving…）。如：
On her arrival she helped me to prepare supper.
20.with fear
该介词短语意为“由于害怕”，with + n.有时用来表示原因，其中的n.常是表示情感的名词。
如：Her face turned pale with fear.
21.by name
该介宾词组的意思是“名叫……”；“凭名字”。如：
①He met a man, John by name.
②I knew him only by name.
22.Training by yourself in a game can be highly dangerous.
