二、考點精析與拓展
1.Something may have happened to her. She might have had an accident.
兩句中都用的“情態動詞may/might +完成時”的結構，有以下用法：
①may/might + have + 過去分詞表示推測過去某動作“可能”發生了。如：
I can’t find my sunglasses, I may/might have left them at the
restaurant yesterday.
一般來說，may和might兩者意思上沒什么區別，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.
在下列情況下，may和might 用法有區別：
句子的主要動詞是現在時，間接引語中用may/might;
句子的主要動詞是過去時，間接引語中只用might.如：
He says that she may/might have misunderstood him.
He said that she might have misunderstood him.
②might + have + 過去分詞，表示對本來可能發生而實際并未發生的動作的感嘆或遺憾含有“責備”、“抱怨”之意，而may + 完成時無此含義。如：
You might have told us earlier.
This medicine might have cured your cough
2.must + have + 過去分詞
表示推測過去某動作“一定發生了”。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意為“跌倒”，“跌跤”。如：
When he was skating, he fell over some times.
4.It was in Greece that Olympic competitions started.
這是強調句型，其結構為：It be + 被強調部分+that-clause.該句型可以對一個句子里的主語、賓語、狀語（介短或從句）進行強調。
5.n.+ being performed in China.
該結構中being performed 是動記號-ing形式的被動語態，在一句子中用在名詞之后，作定語。它常可改寫成一個定語從句。如：
The prices of the TV sets being shown(= which are shown)are still unknown.
6.prepare sb.for…
該短語意為“使某人對……進行準備”。如：
Mother is preparing me for my journey.
prepare 作為動詞，既是及物動詞，又是不及物動詞且常與for連用。如：
Mother asked my sister to prepare lunch.
7.preform exercises to music.
短語意為“伴隨音樂做體操”，從中可知“do sth. to music”判決書為“伴隨音樂做某事”。如：
She likes dancing to music.
她喜歡隨著音樂跳舞。
8.There are safety measures to follow while training.
該句意為“訓練時必須遵守安全措施”，這句話里應注意兩點：
①while training 是從屬連詞與分詞連用，在句子中做時間狀語。結構“when/while + -ing 或過去分詞短語”的使用條件是：
when/while 從句中的主語與主句中的主語相同。如：
You should have dropped in on me when staying here.
除了when/while 外，其他的從屬連詞如if，as if, though, as
before,after等，也有這樣的用法。如：
If heated, ice can be turned into water.
②to follow 是不定式做定語，修飾名詞measures,是主動表被動。在There be 句型中，用不定式做的定語時，即就是不定式與所修飾的名詞之間是動賓關系，也常用不定式的主動語態形式。如：
There is a lot of work to do.
9.think to oneself
該動賓詞組意為“心里想”。如：
She was thinking to herself how cold the room was.
Think aloud意為“自言自語”（=talk to oneself）。如：
He stood there with his lips moving as if he talked to
himself/thought aloud.
10.the moment主語 +Ｖ。
此結構中，the moment 用作連詞，引導一時間狀語從句，意為“一……就……”（=as soon as）。相同意思和用法的表達形式還有：the minute, the instant 和the second。如：
Telephone me the moment you get the results.
11.break off
該短語動詞的意思是“中斷說話”，“暫時停止”。如：
He broke off in the middle of a sentence.
break sth.off/break off sth. with sb.
前者意為“（使）折斷”，后者意為“與某人突然斷絕（關系）”。如：
The mast broke off /was broken off when the ship was moving.
12.be busy doing sth.
該結構意為“忙于做某事”。應注意的是be busy 后只能接動詞-ing形式，不能接動詞不定式to do,相同結構的形容詞還有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…
該句中，go up to…是動詞不定式短語作表語，省略了不定式符號to,這是因為主句的主語被定語從句she did修飾的緣故。語法規定，解釋doing 精確意思的分句，可用不帶to 的動詞不定式。如：
What I can do is (to)help him (to)clean the floor.
14.at the doctor’s
該結構為介詞+名詞所有格，意為“在診所”。所有格-’s后一般接名詞，如her mother’s bike ,但有時這個名詞可省略，主要表現在以下兩個方面：
①指一個企業，機構，教堂，學校，醫院，家庭，理發店，店鋪時。如：
She is at the hairdresser’s.
②為了避免重復，省略-’s后的名詞。如：
I have read some of Shaw’s plays,but none of Shakespeare’s.
15.knock into
該短語意為“把……敲人” ，也可意譯為“撞著某人/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…
意為“看起來好像……”，as if可用as though替換，在此引導表語從句，另外它們也可引導狀語從句，從句既可用陳述語氣，也可用虛擬語氣。如：
①It looks as if /though it’s going to rain.（陳述語氣）
②You look as if you’d seen a ghost.（虛擬語氣）
17. It’s (just)like sb. to do sth.
該句意思是“某人（恰恰）就是……這個樣子”，表示贊揚或不滿；若用否定式，則表示懷疑。如：
It is just like her to think of others before thinking of herself.
18.in a flash
該介賓詞組意為“轉眼間”，“突然間”，“瞬間。”如：
In a flash. I realized where we had met before.
19.on one’s arrival…
該詞組意為“一到達……就……”（= on arriving…）。如：
On her arrival she helped me to prepare supper.
20.with fear
該介詞短語意為“由于害怕”，with + n.有時用來表示原因，其中的n.常是表示情感的名詞。
如：Her face turned pale with fear.
21.by name
該介賓詞組的意思是“名叫……”；“憑名字”。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.
