用以上三种表达方式是:I go to work by bus.I take a/the bus to work.I go to work on a bus.She goes to school by car.She takes a/the car toschool.She goes to school in a car.2.特殊的是ride a bike 而不能说take abikedrive a car 也可以是take acarHe rides a bike to school.He goes to school by bike.He rides to school.可以省略bikeHe drives to school.可以省略carride除了动词骑之外,还有名词一段路程的意思go for a ride去兜风give me a ride 让我搭个便车get sb. a ride打顺车half an hour's ride半小时的路程The bus ride takes me about20 minutes. 公共汽车之旅花费我20分钟。
3.步行到学校Walk to school=go to schoolon footon foot放到句末4.对交通方式提问用how如:I go to school by bike.对by bike提问用 How doyou go to school?5.三个到达:get to/arrive in/at/reach只有reach后面不加介词arrive in+大地点arrive at+小地点6.train ①火车②训练7.take a walk=have a walk 散步go out for a walk出去散步8.What about =how aboutdoing sth?做某事怎么样呢?因为about是介词,后面用动词ing9.hundred百 thousand 千million 百万当前面加数字时它们都不加s当前面没有数字,后面加of 时他们加s如:hundreds of 成百上千的thousands of成千上万的10.本单元有一个最重要的句型:It takes sb.+时间+to do sth.sb.用宾格 take译为花费例如:It takes me ten minutes to goto school on foot.翻译的时候从后往前面翻译:步行去学校花费我十分钟对以上句子中的ten minutes 提问是本单元的第二个重点句型:How long does it take you togo to school on foot?译为:步行到学校需要花费你多久?对这个句型的回答一般用How long,但是因为在原句型中时间前面没有for,所以回答时不用for比较以下两个句子:How long does it take you togo to school on foot?Ten minutes.How far is it from your home to school?Ten minutes' walk.译为:10分钟的路程。
如果是骑车就用:Tenminutes' ride.如果是开车就用:Tenminutes' drive,因为drive 也有名词的形式take 有三种意思:译为:带走,乘坐,花费take sb. to +地点带某人到某地take sb. to do sth带某人去做某事11.比较以下花费a. take 主语是it 后跟to do ,一般指花费时间句型结构是:It takes sb.+时间+to do sth.b. spend 主语是人后跟doing,既可以花费时间,也可以花费金钱句型结构是:Sb.+spend+时间或者金钱+(in)doing sth.Sb.+spend+时间或者金钱+on sth.c. pay 主语是人,与介词for连用,一般指花费金钱句型结构是:Sb.+pay+钱+for+sth.d. cost主语是物,也可以是物,一般指花费金钱句型结构是:It 或者sth cost sb.+钱例如:It takes me half an hour towatch TV every evening.=I spend half an hour (in)watching TV.以上句型不能换为pay和costI paid(这里用pay过去式)100 dollars for the book.pay还有名词报酬,工资的意思=The book cost me 100dollars.at all costs不惜任何代价,无论如何12.对一段距离提问用how far 如:对以下短语提问就用how far ,译为多远five kilometersfive minutes' walkten minutes' ride13.f rom····to···从···到···14.e xercise 名词锻炼不可数exercise 只有做操类,练习题才可数do morning exercises动词,锻炼 do exercise=take exercise=do more exercise15.l ive five kilometers from +地方住的离某地有五公里16.n eed+时间+to do sth.v需要时间做某事need sb. to do sth. 需要某人来做某事need to do sth. 需要做某事17.s top to do sth.停下来去做另一件事(让做这件事)stop doing sth.停止做这件事(不让做这件事)stop ①停止②车站 bus station=bus stop18.当一个特殊疑问句跟在了另一个句子后面时,这个特殊疑问句要用陈述语序。
