　　高三一輪復習的重要知識點

　　不定式做主語：

　　1、不定式做主語一般表示具體的某次動作。===動名詞doing 表示習慣的，經(jīng)常的動作。

　　e.g: To finish the building in a month is difficult.

　　To do such things is foolish.

　　To see is to believe. (對等)

　　注: 1). 不定式作主語時,謂語用單數(shù)

　　2). 當主語較長，謂語較短時，常用it做形式主語，而將不定式放到謂語的后面。

　　it做形式主語，不定式放在謂語動詞之后常用于下列結構中：

　　(1)It is/was +adj.+of sb. to do…

　　(2) It is +adj.+for sb.+to do…

　　It is easy / difficult / hard / foolish / unwise / right / wrong / unnecessary

　　(3) it is +a +名詞+ to do...

　　It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / a shame / a crime / no easy job… to do

　　It takes (sb.) some time / courage / patience …to do…

　　It requires courage / patience / hard work… to do…

　　*注意: probable 和 possible 均可作表語，但possible可以用不定式作真實主語， 而probable不能用不定式作真實主語。

　　It is probable for him to come to the meeting.(錯)

　　It is possible for him to come to the meeting.

　　It is possible / probable that he will come to the meeting.

　　不定式做表語：

　　主語是以aim duty hope idea intention plan job suggestion wish purpose task 等為中心詞的名詞詞組 或以 what 引導的名詞性從句表示，后面的不定式說明其內(nèi)容, 不定式作表語常表示將來或現(xiàn)在的動作或狀態(tài)。

　　eg :My idea is to climb the mountain from the north.

　　Your mistake was not to write that letter.

　　What I would suggest is to start work at once.

　　Worried about the journey, I was unsettled for the first few days.

　　Well-known for their expertise, his parents’ company …..

　　Confused by the new surroundings, I was hit by the lack of fresh air.

　　Exhausted, I slid into the bed and fell fast asleep.

　　過去分詞作狀語：過去分詞作狀語時，說明動作發(fā)生的背景或情況，其等同于一個狀語從句。vt 過去分詞作狀語時與主句主語構成被動關系，表示被動和完成，vi 過去分詞表示狀態(tài)或動作的完成。

　　Heated , water changes into steam .

　　The professor came in, followed by a group of young people .

　　1 作原因狀語，等于as / since / because 引導從句

　　Moved by what she said ,we couldn’t help crying . = ( As we are moved by what she said …

　　2 作時間狀語，等于when 引導時間從句，如果分詞表示的動作與謂語的動作同時發(fā)生，可在分詞前加when/ while / until 等使時間意義更明確。

　　When heated , water can be changed into steam .

　　Seen from the hill ,the park looks very beautiful .= ( When the park is seen from the hill…

　　3 作條件狀語等于 if / whether 引導從句

　　Given more attention , the cabbages could have grown better .= ( If they have been given more attention ….

　　Compared with you , we still have a long way to go = ( If we are compared with you …

　　4 作方式或伴隨狀語

　　The actress came in , followed by her fans .

　　She sat by the window , lost in thought .

　　5 作讓步狀語

　　Much tired ,he still kept on working .=(Although he was tired ,) he ….

　　6 獨立主格結構： 當分詞的邏輯主語不是主句主語時，分詞可以有自己獨立的邏輯主語，這種結構稱為獨立主格結構。常用來表示伴隨情況。

　　The boy rushed into the classroom , his face covered with sweat .

　　All things considered ,your article is of great value than hers .

　　Rewrite with proper conjunctions

　　Example : United we stand, divided we fall.

　　If we are united, we will stand, but if we are divided,we will fall.

　　1 Asked what had happened, he told us about it.

　　→When he was asked what had happened, …

　　2 Well known for his expert advice, he received many invitations to give lectures.

　　→Because he was well known for his expert advice, …

　　3 Given more time, we would be able to do the work much better.

　　一. 過去分詞用在表狀態(tài)的動詞keep,leave等的后面。

　　Eg:They kept the door locked for a long time.

　　Keep your mouth shut and your eyes open.(諺語：少說多看)

　　Don't leave such an important thing undone.

　　Don't leave the windows broken like this all the time.

　　二.過分詞用在get,have,make, 的后面。

　　1.注意“have +賓語+過去分詞”的兩種情況：

　　A)表"讓某人做某事/讓某事(被人)做"

　　eg: I have had my bike repaired.

　　The villagers had many trees planted just then.

　　B)表"遭遇到某種不幸，受到打擊/受....影響，蒙受..... 損失"

　　Eg:I had my wallet stolen on a bus last month.

　　The old man had his leg broken in the accident.

　　He had his leg broken in the match yesterday.(MET1986)

　　2."make+賓語+過去分詞",在這種結構中，過去分詞的動詞必須是表示結果含義的。如：

　　They managed to make themselves understood in very simple English.

　　I raised my voice to make myself heard.

　　三、過去分詞用在感觀動詞watch,notice,see,hear,listen to ,feel,find等后面。如：

　　When we got to school,we saw the door locked.

　　We can hear the windows beaten by the heavy rain drops.

　　He felt himself cheated.

　　The managers discussed the plan that they would like to see carried out the next year.(NMET2000)

　　四、過去分詞用在want,wish,like ,expect等表示“希望，愿望”這一類動詞后面做賓補。

　　The boss wouldn't like the problem discussed at the moment.

　　I would like my house painted white.

　　I want the suit made to his own measure.

　　I wish the problem settled.

　　五、過去分詞用在“with +賓語+賓補”這一結構中，過去分詞與賓語之間是動賓關系。如：

　　The thief was brought in with his hands tied behind his back.

　　With many brightly-coloured flowers planted around the building ,his house looks like a beautiful garden.
