八年級英語語法點及重點短語

1、八年級重點語法句型語法：1、 動詞 1） 情態(tài)動詞（modal verbs)情態(tài)動詞可以用來表示“提議”、“建議”或“請求”等。情態(tài)動詞should作“應該；應當；可以”講，用以表達職責和義務、提出勸告，而且表述的是自己的主觀看法。其后動詞接原型。例如：a用于表示"應該"或"不應該"的概念。此時常指長輩教導或責備晚輩。例如：You should be here with clean hands. 你應該把手洗干凈了再來。b用于提出意見勸導別人。例如：You should go to the doctor if you feel ill.如果你感覺不舒服，

2、你最好去看醫(yī)生。c用于表示可能性。should的這一用法是考試中常常出現(xiàn)的考點之一。例如：We should arrive by supper time. 我們在晚飯前就能到了。She should be here any moment. 她隨時都可能來。情態(tài)動詞could用于有禮貌地向對方提出要求或請求。a. 表示“能力”或“可能性”，作為can的過去形式。如：Could you speak English then？ 那時你能講英語嗎？He said he couldn't follow me. 他說他跟不上我。b. 表示驚異、懷疑、不相信等情緒。如：Who could have

3、taken them？ 誰會把它們拿走了呢？She couldn't have left so soon. 她不可能這么快就走了。在這種情況下，could和can是可以換用的，用could時口氣較緩和，用can時不相信的程度更強一些，兩者在時間上沒有差別。c. 比較委婉客氣地提出問題或陳述看法。如：Could you let me have your passport?Yes, here it is.看看你的護照好嗎？行，這就是。I could come earlier, if necessary. 如果必要我可以早點來。這時could和can沒有時間上的差別。2、 過去進行時（pas

4、t progressive tense）1）過去進行時的定義過去進行時主要表示過去某一時刻正在進行的動作，或表示過去某一階段一直在進行的動作。如：I was having a talk with Li Hua at that time. 那時，我正在跟李華談話。I was watching TV at home last night. 昨晚我一直在看電視。2）過去進行時的結構過去進行時由“was / were + 現(xiàn)在分詞”構成。如：I was doing my lessons then. 那時，我在做功課。We were cleaning the house. 我們在打掃房子。3）使用過去進

5、行時應注意的幾點(1) 過去進行時可表示按計劃、安排過去某時刻將要發(fā)生的動作。如：He said they were leaving for Beijing this afternoon. 他說他今天下午要去北京。(2) 動詞hope, wonder等的過去進行時常用來表示提出要求，雖然表示現(xiàn)在的內容，但語氣比一般現(xiàn)在時或一般過去時要委婉。如：I was wondering whether you could come to join us. 我想你能否過來跟我們一起活動?(3) 過去進行時中有always, forever, continually, constantly修飾時，表示說話人的

6、贊賞或厭煩的感情。如：He was always thinking of others. 他總是想到人家。3、 現(xiàn)在完成時（present perfect tense)1）表示截止現(xiàn)在業(yè)已完成的動作By now, I have collected all the data that I need .到現(xiàn)在為止，我已收集到了我所需的全部資料。She has read 150 pages today .她今天已看了150頁。We haven't met for many years .我們已多年沒見了。They have developed a new product .他們研制成功了一種

7、新產品。2）表示發(fā)生在過去而對現(xiàn)在產生影響、帶來結果的動作Have you had your dinner? 你吃晚飯了嗎?She has been to the United States. 她已去美國了。You have grown much taller.你長高了許多。3）表示過去發(fā)生的動作持續(xù)到現(xiàn)在，并可能還要延續(xù)It has been five years since he joined the army .他參軍五年了。They have learned English for eight years .他們已學了八年的英語了。So far we've only discu

8、ssed the first five chapters.至今我們還只討論了前五章。3、 連詞both and:表示“兩者都”。注意：當bothand 連接主語時，后面動詞一般要用復數(shù)。如：Both Lily and Lucy are right.not only but also: “不僅而且”。注意：后面動詞采用就近原則，與but also后的詞保持一致。如：Not only my parents but also my brother likes the cat.eitheror:“或者或者”。注意謂語動詞采用就近原則。如：Either you or I am wrong.neither

9、nor:“既不也不" 是 “eitheror" 的否定形式。謂語動詞采用就近原則，與nor后的詞保持一致。如：Neither you nor he is right.4、 狀語從句狀語從句專題句法重點狀語從句是中考詞匯和句法部分考查的重點內容之一。狀語的功用：狀語說明地點、時間、原因、目的、結果、條件、讓步等在復習狀語從句時,主要任務是弄清楚引導各種狀語從句的連詞的用法?，F(xiàn)就主要考查點簡述如下:1.引導時間狀語從句的連詞主要有when, while, as, by the time, before, after, since, till/until, as soon as等

10、。其中when while和as都可表示"當時候",但用法有區(qū)別:when意為"在時;當時",可表示"點時間"或"段時間",從句謂語可以是終止性動詞,也可以是延續(xù)性動詞。例如:When I got home, he was having supper.as意為"邊邊"或"與同時",重在表示兩個動作同時發(fā)生。伴隨進行。as從句是終止性動詞時,主句通常也必須是終止性動詞。例如:They sang as they danced.while只可表示"段時間",從句

11、謂語只限于延續(xù)性動詞。例如:While I was sleeping, my father came in.注:從句謂語是持續(xù)性動詞時,when、while和as可以互換2.引導原因狀語從句的連詞原因狀語從句一般由because, since, as, for引導?注意as,because,since和for的區(qū)別:如果原因是構成句子的最主要部分,一般用because。because引導的從句一般不放在句子的開頭。例如:I missed the train because I got up late.注:對于以why開頭的問句,一般只能用because引導的從句來回答。如果原因已為人們所知,或

12、不如句子的其余部分重要,就用as或since、since比as稍微正式一些。as和since引導的從句一般放在句子的開頭。例如:As he was not well,I decided to go there without him.Since this method doesn't work, let's try another.for表示所說的理由是一種補充說明,因此,for引導的從句可以放在括號里,而且for引導的從句一般不放在句子的開頭。例如:I decided to stop and have lunch, for I was feeling quite hungry

13、.3.引導結果狀語從句的連詞主要有so/suchthat,so that等。1) so.that結構在某種情況下可以與enough to和too.to結構相互轉換。例如:She is so short that she can't reach the buttons of the lift. =She is too short to reach the buttons of the lift.2)so that也可以引導結果狀語從句,意為"結果是;以致于"。例如:They missed the bus so that they were late for class

14、. so.that.”句型的意思是“如此/這么以致于”，常引導結果狀語從句，但“so.that.”是個愛“變臉”句型，你一不留意就會出錯?！皊o.that.”句型及其轉換也是中考的熱點，現(xiàn)將其用法總結歸納如下，讓我們一起來看看它是怎樣變的吧。 注意： so. that.句型中的so是副詞，常常用來修飾形容詞或副詞，常用句型為：主語+謂語+so+adj. / adv. + that從句。例如： 1. he is so young that she can't look after herself. 2. The boy ran so fast that I couldn't ca

15、tch him. 3. He was so angry that he couldn't say a word. 在“such. that.”句型中，such修飾名詞，意思也是“如此以致于”但當名詞前有many、much、(a) few、(a) little等詞修飾時，句子中要用“so.that.”而不能用“such.that.”。例如： 1. He has so much money that he can buy what he wanted. 2. I've had so many falls that I have pains here and there. 3. Th

16、ere is litte water in the glass that I can't drink any more.4引導目的狀語從句的連詞so that也可引導目的狀語從句,此時可用to或in order to替換,將其改為簡單句。例如:He got up early so that he could get to school on time. =He got up early to get to school on time. =In order to get to school on time,he got up early. 5. 引導讓步狀語從句的連詞though, a

17、lthough注意： 當有though, although時，后面的從句不能有but，但是 though 和yet可連用 Although it's raining, they are still working in the field.雖然在下雨，但他們仍在地里干活。 He is very old, but he still works very hard.雖然他很老，但仍然努力地工作。 Though the sore be healed, yet a scar may remain.傷口雖愈合，但傷疤留下了。 （諺語）6. 引導條件狀語從句的連詞要點： 表示狀語從句由連詞if,

18、unless (=if not) 引導。1.If it doesnt rain tomorrow, we will go hiking.如果明天不下雨, 我們就去遠足.2.You will get good grades if you study hard.如果你努力學習,就會取得好成績.3.I will go to the party unless he goes there too.我不會去參加聚會的, 除非他也去.(如果他不去,我也不去.)難點提示：用條件狀語從句時要注意時態(tài)的正確使用,當主句是將來時的時候,從句要用一般現(xiàn)在時. 7引導地點狀語從句的連詞(1)地點狀語從句由where，w

19、herever，引導，如： We must camp where we can get water. 我們必須在能找到水的地方露營。 （2）地點狀語從句與定語從句的區(qū)別 where引導定語從句時，從句前應有一個表示地點的名詞作先行詞；而狀語從句前則無需先行詞。如： Go back where you came from.(where引導地點狀語從句) 你從何處來到何處去。 Go back to the village where you came from.(where引導定語從句，修飾village) 回到你來的那個村子里去。重點語法：一般將來時態(tài)的應用 do/does 的一般將來時態(tài)形式：

23、en 后加瞬間動詞，while 后加延續(xù)性動詞。例句：The boy was walking down the street when the UFO landed. =While the boy was walking down the street, the UFO landed.感嘆句結構：(1) How + adj. + the + 主語 + 謂語動詞 =(2) What + (a/an) + adj. + n. + 主語 + 謂語動詞例句：What a beautiful flower it is! =How beautiful the flower is!

25、g. 主句是過去時態(tài)，賓語從句也要用過去時態(tài)。 例句：He said I was good at mathematics when I was young yesterday.
