7、er/any more. Hes an engineer now.2) He no longer lives here. = He doesnt live here any longer/any more. Hes living in another city.2.Theres something wrong with your ears.There + be + something/nothing wrong with. . .是一個(gè)固定的句型，意思是“出/沒(méi)毛病問(wèn)題。它的同義句是Something/Nothing + be wrong with. . .如：1) There is some

8、thing wrong with your computer. = Something is wrong with your computer. Its not working now.2) There is nothing wrong with the new bike. = Nothing is wrong with the new bike. Its quite OK.疑點(diǎn)：1.短語(yǔ)toototooto句型的意思是“太以致不能，too是副詞，后面接形容詞或副詞，to是動(dòng)詞不定式的標(biāo)志，后接動(dòng)詞原形。該句型雖然沒(méi)有否認(rèn)詞not或no，但具有否認(rèn)的意義。假設(shè)需要加上人稱(chēng)，那么在不定式之前加f

9、or sb。如：1) The sentence is too difficult to understand. Please give me an easy one.2) These apples are too high for us to reach. Wed better get a ladder.2.Wed better not go there. Its too far from here.had better后面接動(dòng)詞原形，其否認(rèn)形式是had better no+動(dòng)詞原形。had不受人稱(chēng)限制，不可以說(shuō)havehas better。如：Girls had better not go

10、out at night. They had better stay at home.2. Weve never been there before.該句型 have; has been to+地點(diǎn)名詞表示某人曾去過(guò)某地，現(xiàn)在已離開(kāi)那個(gè)地方或已回來(lái)。假設(shè)地點(diǎn)是副詞那么“to省略。如：We have never been to Shanghai. But they have been there for three times. They can tell us a lot about Shanghai.3. We wont go until we get it back again!本句中的u

11、ntil作連詞，引導(dǎo)一個(gè)時(shí)間狀語(yǔ)從句。notuntil意為“直到才，“在之前不，主句中的謂語(yǔ)動(dòng)詞一般是非延續(xù)性動(dòng)詞，如leave，finish，begin，go，start等，until引導(dǎo)的時(shí)間狀語(yǔ)從句中將來(lái)時(shí)用一般現(xiàn)在時(shí)表示。如：They wont leave their school until their teacher returns. They will ask the teacher many questions until they are able to do these exercises. 口語(yǔ)訓(xùn)練 本單元的口語(yǔ)訓(xùn)練主要包括兩項(xiàng)內(nèi)容表示距離遠(yuǎn)近的用法。不定代詞和副詞的用法

12、。1表示距離遠(yuǎn)近的用法在學(xué)生熟練掌握第73課第二局部?jī)?nèi)容的根底上，先回憶一下以前學(xué)生用書(shū)中所出現(xiàn)的一些有關(guān)距離的表示法。如How far is it/ Is it far/ Its/quite nearIts aboutkilometers farthestfurthest等。同時(shí)復(fù)習(xí)一下far這個(gè)詞的不規(guī)那么比擬級(jí)形式和最高級(jí)形式。farfartherfurtherfarthestfurthest，告訴學(xué)生nearclose的比擬級(jí)和最高級(jí)形式的變化是規(guī)那么的。老師可以給學(xué)生一些提示，讓學(xué)生相互之間展開(kāi)由易到難的練習(xí)。1編制一些簡(jiǎn)單的問(wèn)句問(wèn)學(xué)生。如：How far is it from yo
