九年級英語上冊unit12知識要點(diǎn)

1、九年級英語上冊Unit12 Life is full of the unexpected.一、語法：過去完成時(shí)過去完成時(shí)表示在過去某一時(shí)間點(diǎn)以前即“過去的過去”已經(jīng)發(fā)生的動作。Mr. Black told me that he had seen the movie three times.布萊克先生告訴我他已經(jīng)把這部電影看了三遍了。（“看”在“告訴”之前）1、構(gòu)成：had+動詞過去分詞 肯定句：主語+had+動詞的過去分詞+其他.否定句：主語+hadnt(had not)+動詞的過去分詞+其他.一般疑問句：Had+主語+動詞的過去分詞+其他？肯定回答：Yes, 主語+had.否定回答：No,

2、主語+hadnt. 2、基本用法：表示在過去某一時(shí)刻或動作以前完成了的動作，即“過去的過去”。常用時(shí)間狀語by + 過去的時(shí)間點(diǎn)“到時(shí)”；by the end of“到末（為止）”；before + 過去時(shí)間“在之前”；by then“截止到那時(shí)”；up till then“直到那時(shí)”；up till last night“直到昨晚”；when、before等引導(dǎo)的時(shí)間狀語從句等。 I had finished reading the novel by nine o'clock last night.到昨天晚上10點(diǎn)鐘時(shí)我就看完了這本小說。 We had learned over tw

3、o thousand English words by the end of last term. 到上個(gè)學(xué)期末我們以學(xué)了兩千個(gè)英語單詞。 They had planted six hundred trees before last Wednesday. 上周三之前他們已經(jīng)栽了六百棵樹。 When I got there，the train had left.當(dāng)我到達(dá)那兒時(shí)，火車已經(jīng)開了。 表示由過去的某一時(shí)刻開始，一直延續(xù)到過去另一時(shí)間的動作或狀態(tài)，常和for, since構(gòu)成的時(shí)間狀語連用。He said he had worked in that factory since 1949.他

4、說自從1949年以來他就在那家工廠工作。 3、過去完成時(shí)的判定： 由時(shí)間狀語來判定 一般說來，各種時(shí)態(tài)都有特定的時(shí)間狀語。與過去完成時(shí)連用的時(shí)間狀語有： by the end of“到末（為止）”；before + 過去時(shí)間“在之前”由“過去的過去”來判定。過去完成時(shí)表示“過去的過去”，是指過去某一動作之前已經(jīng)發(fā)生或完成的動作，即動作有先后關(guān)系，動作在前的用過去完成時(shí)，在后的用一般過去時(shí)。這種用法常出現(xiàn)在：1）賓語從句中當(dāng)賓語從句的主句為一般過去時(shí)，且從句的動作先于主句的動作時(shí)，從句要用過去完成時(shí)。在told, said, knew, heard, thought等動詞后的賓語從句。如：She

5、 said that she had seen the film before.2）狀語從句中在時(shí)間、條件、原因、方式等狀語從句中，主、從句的動作發(fā)生有先后關(guān)系，動作在前的，要用過去完成時(shí)，動作在后的要用一般過去時(shí)。如：After he had finished his homework, he went to bed.注意： before, after 引導(dǎo)的時(shí)間狀語從句中，由于 before 和 after 本身已表達(dá)了動作的先后關(guān)系，若主、從句表示的動作緊密相連，則主、從句都用一般過去時(shí)。如：After he closed the door, he left the classroom.

6、根據(jù)上、下文來判定。I met Tao Wang in the street yesterday. We hadn't seen each other since he went to Beijing.語法區(qū)別(一)、過去完成時(shí)與現(xiàn)在完成時(shí)的區(qū)別現(xiàn)在完成時(shí)表示的動作發(fā)生在過去，但側(cè)重對現(xiàn)在產(chǎn)生的結(jié)果或造成的影響，與現(xiàn)在有關(guān)，其結(jié)構(gòu)為“助動詞 have (has) + 過去分詞”；過去完成時(shí)則是一個(gè)相對的時(shí)態(tài)，它所表示的動作不僅發(fā)生在過去，更強(qiáng)調(diào)“過去的過去”，只有和過去某時(shí)或某動作相比較時(shí)，才用到它。比較：I have learned 1000 English words so far

7、.到目前為止我已經(jīng)學(xué)會了1000個(gè)英語單詞。I had learned 1000 English words till then.到那時(shí)為止我已經(jīng)學(xué)會了1000個(gè)英語單詞。 I'm sorry to keep you waiting. 對不起，讓你久等了。 Oh, not at all. I have been here only a few minutes.沒什么，我只等了幾分鐘。（“等”的動作從過去某一時(shí)間點(diǎn)持續(xù)到現(xiàn)在）(二)、過去完成時(shí)與一般過去時(shí)的區(qū)別雖然這兩種時(shí)態(tài)都表示過去發(fā)生的動作或存在的狀態(tài)，但在使用時(shí)應(yīng)注意以下幾點(diǎn)：1. 時(shí)間狀語不同：過去完成時(shí)在時(shí)間上強(qiáng)調(diào)“過去的過去

8、”；而一般過去時(shí)只強(qiáng)調(diào)過去某一特定的時(shí)間。比較：They had arrived at the station by ten yesterday.They arrived at the station at ten yesterday.2. 在沒有明確的過去時(shí)間狀語作標(biāo)志時(shí)，謂語動詞動作發(fā)生的時(shí)間先后須依據(jù)上下文來判斷：先發(fā)生的用過去完成時(shí)，后發(fā)生的則用一般過去時(shí)。She was very happy. Her whole family was pleased with her, too. She had just won the first in the composition compet
