魯教版初二下冊英語u3 知識點

1、unit 3 will people have robots?知識點：1、一般將來時a) 一般將來時的構(gòu)成：由助動詞shall或will加動詞原形構(gòu)成，shall用于第一人稱。在口語中，will在名詞或代詞后常簡略為ll， will not常簡略為wont。這個時態(tài)的肯定，否定和疑問結(jié)構(gòu)可表示如下：肯定句否定句疑問句i (we)shall(will) go.you(he, she, they) will go.i(we)shall(will) not go.you(he, she, they)will not go.shall i(we) go?will you (he, she, they)

2、 go?用”be going to +動詞原形”也可表示將來時，表示將要發(fā)生的事，打算或決定要做的事。i think it is going to snow.我看要下雪。b)一般將來時的用法：1）表示將要發(fā)生的動作或情況；2） 不以人的意志為轉(zhuǎn)移，肯定要發(fā)生的事情。the day after tomorrow will be national day.后天是國慶日。 c) 一般將來時的時間狀語標(biāo)志詞： 1.含tomorrow; next短語； 2.in+段時間 ；3.how soon； 4.by+將來時間； 5.by the time sb.do6.祈使句句型中：or/and sb. will

3、 do7.在時間/條件狀語從句中, 如果從句用一般現(xiàn)在時, 主句用將來時（主將從現(xiàn)） 8.another day 2、in 與 after的區(qū)別in是指以現(xiàn)在時間為起點的“在一段時間以后”。也可以表示“在將來多少時間之內(nèi)”，句子中的謂語動詞要用一般將來時態(tài)；after常指以過去時間為起點的“一段時間之后”，所以它與過去時態(tài)連用。當(dāng)after指某個特定的未來時刻或日期之后，或指以將來某一時間為起點的若干時間之后時，它可以與將來時態(tài)連用。例句：ill be back in half an hour. 我半小時后就回來.4) “after+一段時間”或“一段時間+later”表示“（在過去某個時間看

4、來）一段時間之后”。he went home after two days. 他兩天后回家了。three years later，she had a baby. 三年后，她生了一個嬰兒。3.fall的短語：n.秋天，秋季v.掉落，掉下（1）fall in love with 愛上 (2)fall behind:落在的后面e.g. work harder,or you will fall behind others. (3)fall off:從上掉下來e.g. mary fell off the ladder（梯子） last night.4、there be結(jié)構(gòu) 英語中,there be句型常

5、表示某處有某人或某物。there will be 是there be句型的將來時態(tài)。e.g. there wont be any paper money. （否定）will there be less pollution? (疑問) yes, there will./ no, there wont. there will be more people. (肯定)常見錯誤：there will have 1)there與be中間可插入一些表示推測的情態(tài)動詞、表示時態(tài)的短語和一些動詞短語,以強調(diào)某種語氣。例如:there must be some flowers in the box. 盒子里肯定

6、有些鮮花。2)there be句型常與過去時間狀語連用,構(gòu)成一些固定句型,用于故事發(fā)生的開頭,交代故事發(fā)生的時間。many years ago,there was such a beautiful girl called cindy.很久以前有一個叫cindy的美麗女孩。3)there be句型可換成there come / go,以引起注意,加強語氣。 there comes the bus.公共汽車來了。4)there be句型或there加其他動詞的句型,其動詞的單復(fù)數(shù),常采用就近一致的原則。例如:there is a desk, two chairs and three benches

7、 in the room. there are two chairs, a desk and three benches in the room. 5)there be或there加其他動詞的句型,其反意疑問句一律用there？ 例如:there is a cat in the garden, isnt there？ 5、 people, person, folks, human: people“人們“全體；person “人”（不分年齡，性別它包括men, women, children.它可做people的單數(shù)形式可以說every person但不能說one people. person指

8、“人們”時著重個體；folks“人們”，指一般人或特殊年齡位置，境遇等特殊級的人；human主要用來區(qū)別于其他動物。征對性練習(xí)一. 根據(jù)句意，用括號中動詞的適當(dāng)形式填空。1. we_(go) fishing tomorrow. 2. what are you going_(do) this evening?3. would you like to play football with us?id love to. but i_(help) my mother after lunch.4. is your brother in? yes. but he_(leave) for england s

17、般現(xiàn)在時表示經(jīng)常狀態(tài)，用現(xiàn)在進行時表示暫時狀態(tài)。egwe wear our rain boots on a rainy day. 我們在下雨天穿雨鞋。she is wearing a new coat 她穿著一件新衣服。put on是“穿上”，“戴上”的意思，強調(diào)動作。egshe put on a red coat and went out. 她穿上紅色大衣出去了。 注意：put on是一時的動作，不能跟表示一段時間的狀語連用。他整天戴著草帽。 誤：he puts on a hat all day. 正：he wears a hat all day2、seem的用法：1)seem to do似

18、乎he seems to think so.2)it seems that看來it seems that he is lying. 3) seem +adj./n.好象是 he seems ill.3、would like sth意思為“想要某物“； would like to do意思為 “想要做某事”?；卮饂ould like句型的一般疑問句時，其肯定回答為 “yes, please.”;否定回答“no, thanks”或 “id like /love to, but.”4、.make sb. do; make +n+adj.; make friends with sb.; make +n

19、./ pron.+n.5、. such作形容詞，意思是“如此的”“這樣的”，修飾各種名詞。 such這樣的。如it is such bad weather.天氣如此惡劣。 such常和as搭配，表示一種類別。如we enjoy such a voice as hers.我們喜歡象她那樣的嗓子。 such常和表示結(jié)果的that從句搭配，表示“如此.以至于”如 it was such a hot day that we all had to stay at home. suchthat和sothat都可用來引出一個結(jié)果狀語從句。由于such是形容詞，所以that從句前有一個受such修飾的名詞；而

20、so 是副詞，用以修飾形容詞或副詞，因此that從句前一般不出現(xiàn)名詞。如 they are such kind-hearted teachers that people in the village all respect them. the exam was so difficult that many students failed to pass it.a) 如果名詞是可數(shù)名詞的單數(shù)形式，such和so的位置不同：such+a/an+形容詞+單數(shù)名詞 so+形容詞+a/an+單數(shù)名詞b) 如果名詞是不可數(shù)名詞或名詞復(fù)數(shù)，只可用such,不能用so.:such+adj.+不可數(shù)名詞或復(fù)數(shù)名

21、詞c) 如果被修飾的不可數(shù)名詞被much, little, 或復(fù)數(shù)名詞被many, few等表示量的形容詞修飾時，用so，不用such.d) 當(dāng)little表示“年紀(jì)小的”時，可用such+little+名詞 there were such little children that they couldnt clean the room.5、use的短語：(1)be used by:被使用 e.g. rockets are used by astronauts.

23、lonely不同，lonely表示“孤獨的，寂寞的”含有豐富的感情色彩.lonely做形容詞時，可做定語和表語。如: a lonely village 孤寂的村莊.8、fly to飛往= go to +地點+by plane/air jim is flying to beijing next week. =jim is going to beijing by plane next week.9、probably與maybe 但比maybe可能性更大10、it will be + adj. + for sb. to do sth. 征對性練習(xí)一般現(xiàn)在時，一般過去時，現(xiàn)在進行時的區(qū)別。1、i _
