Unit 4 Dont eat in class. Section A1. Dont arrive late for class.上课不要迟到。(1)这是祈使句。祈使句的功能在于向对方发出指令、请求等;祈使句通常省略主语,以动词原形开头;否定形式的祈使句构成为:Dont+动词原形。如:Be careful while crossing the road.过马路时要小心。Dont forget me!不要忘记我!(2)arrive意思是“到达”,其后不能直接跟地点名词;arrive at后可接小地点,arrive in后多接大地点。如:What time did you arrive at the station?你是几点钟到火车站的?Can we arrive in Beijing on time or not?我们能否按时到达北京?(3) be late for class意思是“上课迟到”,是习惯搭配,class前不用冠词。类似搭配还有:be late for school上学迟到如:I wish you do not be late for school any more.我希望你以后上学别再迟到了。2. You must be on time.你必须守时。(1)must是情态动词,意为“必须”,表示命令的语气;情态动词后必须跟实义动词原形,be是is,am,are的原形。如:When you learn to ride a bike you must learn to balance.你学骑脚踏车时必须学会保持平衡。(2)on time意思是“准时”。如:The plane arrived on time.飞机正点到达。【辨析】on time与in timein time的意思是“及时”,“终有一天”,“最后”,“迟早”或“终于”。例如:I wish you would come in time.我希望你及时赶到。We got to the station just in time to catch the bus.我们及时到达车站,赶上了公共汽车。on time意为是“准时”,“准点”,“正点”。The train arrived on time.火车正点到达。Please be here tomorrow on time.请明天准时到这儿来。3. Dont listen to music in class.不要在教室里听音乐。(1)listen to意思是“听”,表示“听”的动作过程。如:She turned on the MP3 to listen to music.她打开MP3听音乐。【辨析】listen,listen to与hearhear与listen这两个词都是动词,都有“听”的意思。但意思有区别,用法也不同。hear是及物动词,表示“听见”、“听到”,可能是有意识地听,也可能是无意识地听。如:Louder,please.I cant hear you.请大声点,我听不到你的声音。We heard someone laughing in the next room.我们听见隔壁有人在笑。hear还可作不及物动词,后接of(about)表示“听别人说”(指间接听到) ;后接from意思是“收到(某人)的来信”。如:I have never heard of such a thing.我从未听说过这种事。Have you heard from him?你收到他的来信了吗?listen是不及物动词,表示有意识或注意地“听”,不说明是否听见的结果;必须加to才能接宾语。如:I listened but heard nothing.我注意听了,但什么也没听见。【易错警醒】hear一词一般不用于进行时。不说I am hearing或I was hearing,而用can或could。如:I can hear somebody coming.我能听见有人来了。(2)in class是习惯搭配,意思是“在上课中,在课堂上”。4. Dont run in the hallways.不要在过道上奔跑。Sorry. Ms. Clark.对不起,克拉克女士。(1)run意思是“跑,跑步”;run是不及物动词,其后不能接宾语。run组成的短语有:run after追赶;run away逃跑;run out of用完,耗尽。(2)sorry意思是“对不起,遗憾”;因自己的过失或不当影响到他人时,通常以sorry表示道歉。如:Im sorry. You have the wrong number.对不起,你的电话号码不对。5. This is a great school,but there are a lot of rules.这是一所很不错的学校,但有很多校规。(1)but是连词,意思是“但是”;“学校不错”与“有很多校规”为转折关系,用but连接意义转折的两个单句。如:I can see that plane,but I cant see a bird.我能看见那架飞机,但是小鸟我就看不见了。He may be clever,but he doesnt know everything.他或许聪明,但是他不可能知道所有的事情。(2)there be意思是“有”,表示“某处有某物”;there be结构中,be与紧跟其后的名词保持数的一致。如:There is an old pine tree in front of the house.房子前面有一株老松树。There are some nice apples on sale in that shop.那家商店有些很好的苹果出售。(3)a lot of意思是“很多,大量”,修饰不可数名词,也可修饰可数名词复数。如:We have a lot of fun in the park.我们在公园里玩得很快活。There are a lot of wild animal parks in South Africa.在南非有许多野生动物园。【辨析】many,much与lots of,a lot ofmany用来修饰可数名词,表示数目,反义词为few。如:There are many apples in the basket.篮子里有许多苹果。much用来修饰不可数名词,表示量,反义词为little。如:Im sorry to give you so much trouble.真对不起,给你添了这么多的麻烦。a lot of(lots of)既可修饰可数名词又可修饰不可数名词。修饰可数名词时可与many换用;修饰不可数名词时,可与much换用。如:We had a lot of(lots of) fun at the picnic. =We had much fun at the picnic.我们在这次野餐中玩得很痛快。There are a lot of(lots of) pear trees near the house. =There are many pear trees near the house.屋子附近种着许多梨树。6.
