1、Unit 3Could you please tell mewhere the restrooms are？第1课时(Section A 1a3b)单 词1need点拨need 在句中用作实义动词，意为“需要”。need 后面需要接带 to 的动词不定式，表示有义务或责任去做某事。如：Will we need to show our passports?我 们 需 要 出 示 护 照吗？拓展need 的其他用法：(1)need sth.(需要；必须)，need 后的宾语可以是名词，也可以是代词。如：We need a great deal of money now.现在我们需要很多钱。(2)n

2、eed doingneed to be done，need 后面可跟动名词做宾语，这种情况下应注意两点：主动形式的动名词 doing 具有被动的含义；该动名词可以改为其动词不定式的被动形式而句子的意义不变。如：The door needs painting.The door needs to be painted.那扇门需要油漆一下。(3)need 做情态动词时，具有情态动词的一般性质：没有人称和数的变化；不能单独充当谓语；变为否定句时只需在情态动词之后加 not；变为疑问句时只需将情态动词提到主语的前面。如：Need I type this letter again?我需要重新录入这封信吗？

3、There is enough time.You neednt hurry.有的是时间，你不必着急。The president wondered whether he need send more soldiers.总统不知道他是否要增兵。现在我必须交作业吗？Must I hand in my homework now?No,you neednt.不，你不必。2suggest点拨suggest 做动词，意为“建议”。其用法如下：(1)suggest名词/代词或 suggest名词/代词tosb.，但不能说 suggest sb.sth.，即不能加双宾做宾语。如：We suggest the p

4、lan to him.我们向他提出建议。(2)suggestdoing sth.意为“建议做某事”。如：He suggested going out for a walk.他建议出去散步。(3)suggest(that)主语(should)dosth.，其中的 should可以省略。如：He suggested that you should go there tomorrow.Hesuggested you go there tomorrow.他建议你明天去那儿。第2课时(Section A Grammar Focus4c)语 法含特殊疑问词的宾语从句点拨(1)在引导词上，要将疑问代词或疑问

5、副词变为连接代词或连接副词，引导宾语从句。如：Whose bike is this？Does anybody know？Does anybodyknow whose bike this is?(2)宾语从句的时态应与主句的时态保持一致。如：When the train will arrive？He asked me.He asked mewhen the train would arrive.(3)在语序上，要将疑问句语序改为陈述句语序。如：Which one do you like best？She asked me.She asked mewhich one I liked best.注意

6、：疑问句中主语之前的助动词若是 do/does/did，变为宾语从句时，要先将其去掉，谓语动词再根据时态做相应的变化。(4)特殊疑问词在句中做主语，变为宾语从句时语序不变(时态应做相应变化)。如：Who can answer the question？The teacher asked.Theteacher asked who could answer the question.(5)特殊疑问句变为宾语从句后，用问号还是用句号完全取决于主句的句式：若主句为陈述句或祈使句，句末就用句号；若主句是疑问句，句末就用问号。如：I dont know when we shall start tomorr

7、ow.我不知道明天我们什么时候开始。Do you know when we shall start tomorrow？你知道明天我们什么时候开始吗？第3课时(Section B)单 词1enough点拨enough 用作形容词，能在句中做表语或定语。做定语时，通常修饰复数名词或不可数名词，可放在被修饰名词之前或之后。如：He has enough money to buy a car.他有足够的钱买辆汽车。We have time enough to get to the airport.我们有足够的时间赶到机场。链接(1)enough 做形容词，与某些具有形容词意味的名词连用时，enough

8、 必须后置，且该名词通常不用冠词。如：I was fool enough to accept his offer.我接受他的提议真是太傻了。(2)enough 还可用作副词，修饰形容词、副词、动词等，此时总是放在被修饰词之后。如：He didnt practise enough.他练习得不够。2depend点拨depend 做动词，意为“依靠；依赖；指望”，常与 on 或 upon 连用，后接名词或代词。如：We shouldnt depend on foreign countries for oil.我们不应当依赖外国的石油。链接depend on/upon sb.to do sth.意思是“指望某人做某事”，相当于 depend on one(s)doing sth.。如：You cant depend on them to do it.You cant depend ontheir/them doing it.你不能指望他们做这事。
