Unit 3Could you please tell mewhere the restrooms are？第1課時(Section A 1a3b)單 詞1need點(diǎn)撥need 在句中用作實(shí)義動詞，意為“需要”。need 后面需要接帶 to 的動詞不定式，表示有義務(wù)或責(zé)任去做某事。如：Will we need to show our passports?我 們 需 要 出 示 護(hù) 照嗎？拓展need 的其他用法：(1)need sth.(需要；必須)，need 后的賓語可以是名詞，也可以是代詞。如：We need a great deal of money now.現(xiàn)在我們需要很多錢。(2)need doingneed to be done，need 后面可跟動名詞做賓語，這種情況下應(yīng)注意兩點(diǎn)：主動形式的動名詞 doing 具有被動的含義；該動名詞可以改為其動詞不定式的被動形式而句子的意義不變。如：The door needs painting.The door needs to be painted.那扇門需要油漆一下。(3)need 做情態(tài)動詞時，具有情態(tài)動詞的一般性質(zhì)：沒有人稱和數(shù)的變化；不能單獨(dú)充當(dāng)謂語；變?yōu)榉穸ň鋾r只需在情態(tài)動詞之后加 not；變?yōu)橐蓡柧鋾r只需將情態(tài)動詞提到主語的前面。如：Need I type this letter again?我需要重新錄入這封信嗎？There is enough time.You neednt hurry.有的是時間，你不必著急。The president wondered whether he need send more soldiers.總統(tǒng)不知道他是否要增兵?，F(xiàn)在我必須交作業(yè)嗎？Must I hand in my homework now?No,you neednt.不，你不必。2suggest點(diǎn)撥suggest 做動詞，意為“建議”。其用法如下：(1)suggest名詞/代詞或 suggest名詞/代詞tosb.，但不能說 suggest sb.sth.，即不能加雙賓做賓語。如：We suggest the plan to him.我們向他提出建議。(2)suggestdoing sth.意為“建議做某事”。如：He suggested going out for a walk.他建議出去散步。(3)suggest(that)主語(should)dosth.，其中的 should可以省略。如：He suggested that you should go there tomorrow.Hesuggested you go there tomorrow.他建議你明天去那兒。第2課時(Section A Grammar Focus4c)語 法含特殊疑問詞的賓語從句點(diǎn)撥(1)在引導(dǎo)詞上，要將疑問代詞或疑問副詞變?yōu)檫B接代詞或連接副詞，引導(dǎo)賓語從句。如：Whose bike is this？Does anybody know？Does anybodyknow whose bike this is?(2)賓語從句的時態(tài)應(yīng)與主句的時態(tài)保持一致。如：When the train will arrive？He asked me.He asked mewhen the train would arrive.(3)在語序上，要將疑問句語序改為陳述句語序。如：Which one do you like best？She asked me.She asked mewhich one I liked best.注意：疑問句中主語之前的助動詞若是 do/does/did，變?yōu)橘e語從句時，要先將其去掉，謂語動詞再根據(jù)時態(tài)做相應(yīng)的變化。(4)特殊疑問詞在句中做主語，變?yōu)橘e語從句時語序不變(時態(tài)應(yīng)做相應(yīng)變化)。如：Who can answer the question？The teacher asked.Theteacher asked who could answer the question.(5)特殊疑問句變?yōu)橘e語從句后，用問號還是用句號完全取決于主句的句式：若主句為陳述句或祈使句，句末就用句號；若主句是疑問句，句末就用問號。如：I dont know when we shall start tomorrow.我不知道明天我們什么時候開始。Do you know when we shall start tomorrow？你知道明天我們什么時候開始嗎？第3課時(Section B)單 詞1enough點(diǎn)撥enough 用作形容詞，能在句中做表語或定語。做定語時，通常修飾復(fù)數(shù)名詞或不可數(shù)名詞，可放在被修飾名詞之前或之后。如：He has enough money to buy a car.他有足夠的錢買輛汽車。We have time enough to get to the airport.我們有足夠的時間趕到機(jī)場。鏈接(1)enough 做形容詞，與某些具有形容詞意味的名詞連用時，enough 必須后置，且該名詞通常不用冠詞。如：I was fool enough to accept his offer.我接受他的提議真是太傻了。(2)enough 還可用作副詞，修飾形容詞、副詞、動詞等，此時總是放在被修飾詞之后。如：He didnt practise enough.他練習(xí)得不夠。2depend點(diǎn)撥depend 做動詞，意為“依靠；依賴；指望”，常與 on 或 upon 連用，后接名詞或代詞。如：We shouldnt depend on foreign countries for oil.我們不應(yīng)當(dāng)依賴外國的石油。鏈接depend on/upon sb.to do sth.意思是“指望某人做某事”，相當(dāng)于 depend on one(s)doing sth.。如：You cant depend on them to do it.You cant depend ontheir/them doing it.你不能指望他們做這事。
