Wemuststopplayingcomputergames.It'stimeforclass.我们必须停止玩电子游戏，该上课了。2）stop作名词，意为“停止;逗留，车站”=station例如：Iwillwaitforyouatthebusstop.我会在公共汽车站等你。四、知识点hundredhundred是数词，意为“百”，当表示具体的“几百”时，用“基数词+hundred”，注意不加-s。例如：Thereareninehundredstudentsinourschool.我们学校有900名学生。拓展:1）hundredsof表示“数百，成百上千的”这时hundred后要加-s，且后面有介词of，但是不能与数词连用。例如：Therearehundredsofpeopleintherestaurant.在餐馆里有成百上千的人。2）表示数词的还有thousand“千”，million“百万”，billion“十亿”。它们的用法和hundred一样，可以用来表示约数和确数。例如：Therearethousandsofpeoplearewaitingtoseethemoviestar.数千人在等着见那个电影明星。五、知识点表示“乘……”的几种表达方式1）用介词短语来表示交通方式，介词短语在句中作状语。(1)用“by+交通工具名词”表示交通方式。例如：bybike骑自行车bycar乘小汽车bybus乘公共汽车用“by+交通路线的位置”来表示交通方式。例如：bywater由水路byland从陆路bysea从海路byair乘飞机(3)用“in/on+冠词/形容词性物主代词/指示代词+交通工具名词”表示交通方式。其中，in多用在car等交通工具之前，而on多用在bike/horse/bus/train/ship等交通工具之前，它们的用法与“by+交通工具名词”的用法相同。例如：Sheoftengoestoschoolona/herbike.=Sheoftengoestoschoolbybike.她经常骑自行车上学。(4)onfoot步行。onfoot是固定搭配，表示步行，其中foot不能用复数形式feet，其前也不加任何修饰词。例如：Sheoftengoestoschoolonfoot.她经常步行去上学。2）用动词短语表示交通方式，动词短语在句中作谓语。(1)用“take+a/the+交通工具名词”表示交通方式。例如：takeatrain乘火车takeabus乘公共汽车takeaship乘船takeaplane乘飞机注意：“骑自行车”要翻译为“rideabike”(2)用某些动词来表示交通方式。例如walkto步行去driveto开车去rideto骑车/马去注意：如果接地点副词here;there;home时，介词to应该省略。知识点Ittakessb.sometimetodosth.1）Ittakessb.sometimetodosth.是固定句型，意为“做某事需要花费某人多长时间”。take在此意为“花费”，it是形式主语，真正的主语是后面的不定式todosth.，对这个句式中的时间提问时用howlong。例如：Ittakesmehalfanhourtofinishmyhomeworkeveryday.我每天花费半个小时的时间做作业。Howlongdoesittakeyoufromyourhometoschool从学校到你家要花多长时间？2）动词spend也有“花费多长时间做某事”的意思，但句式和take不同。它的句式是“sb.spends+时间或金钱+(in)doingsth./onsth.”。例如：Ispendabout3hours(in)doing/onmyhomeworkeveryday.我每天花大约三个小时做作业。知识点cross1）cross作动词，意为“横过，越过”，指从表面上横过。例如：Theycrosstherivereveryday.他们每天都要过河。Crosstheroad,youwillseethestore.过了马路，你就会看到那个商店。2）cross作名词，意为“十字架，十字形饰物；画十字的动作”。例如：Jesusdiedonthecross.耶稣死在十字架上。Hemadeacrossoverhishead.他在他头上画了一个十字。拓展：across和cross的区别这两个词都是“横越,横跨，横穿”的意思，但是cross是动词可以单独作谓语；但是across是介词，需要和动词一起构成谓语。例如：Theycrossthestreettogotoschooleveryday.Theywalkacrossthestreettogotoschooleveryday.知识点.beafraid…afraid是形容词,意为“害怕的,恐惧的”。常和系动词一起构成系表结构。例如：Iamnotafraid.我不害怕。句式beafraid是afraid最常用的形式，其常见的用法有：1）beafraidof①beafraidof后跟名词或者代词，意为“害怕某人或某物”。例如:Areyouafraidofdogs你害怕狗吗

Sheseemsverymuchafraidofhim.她好像很害怕他。②beafraidofdoingsrh.，意为“怕做某事或不敢做某事”。例如：I’mafraidoftellingher.我不敢告诉她。Heisafraidofjumping.他不敢跳。2）beafraidtodosth.意为“害怕做某事或不敢做某事”。例如：Heisafraidtoflyinaplane.他不敢坐飞机。注意：表示担心会发生某事或某情况，只能用beafraidof,而表示“害怕做某事或不敢做某事”时，既可以用beafraidof也可以用beafraidto。例如：Don’tbeafraidtoask(ofasking)question.不要害怕问问题。Heisafraidtogoout(ofgoingout)aloneatnight.他不敢晚上一个人出去。3）beafraidthatbeafraidthat后跟一个完整的句子，意为“担心/恐怕……”。例如:Heisafraidthatshewillnotcome.他担心她不会来。IamafraidIcan’thelpyou.恐怕我帮不了你。在日常口语中,“I’mafraidthat…”在很多场合相当于“I’msorry,but…”。用于提出异议，说出令人不快的事实,拒绝对方的要求等,使语气委婉。例如:I'mafraidIdon'tunderstand.抱歉，我不明白你的意思。I’mafraidyouarewrong.(Youarewrong,I’mafraid.)恐怕你错了。4）在口语中I’mafraidso.和I’mafraidnot.常用作简略答语。例如:－Isitgoingtoraintomorrow明天会下雨吗

－I’mafraidso.恐怕会。－I’mafraidnot.恐怕不会。九、知识点thinkof1）thinkof意为“认为，想起，考虑”等。后跟名词、代词、动名词等形式。例如：Whatareyouthinkingof你在想什么

Shewillsmilewhenshethinksofhergoodfriends.当她想起她的好朋友时她就会微笑。2）thinkof当“考虑,对……有某种看法”讲时可以和thinkabout互换。例如:Don’tthinkof（about）meanymore．不要再考虑我。They’rethinkingabout（of）buyinganewcar．他们正在考虑买一辆新车。常见的think构成的词组还有thinkover，意为“仔细考虑”。例如：Thinkover，andyou’llfindaway．仔细考虑一下，你就会有办法的。十、知识点疑问词意思用法例句who谁问人的身份，姓名等HeisLiLieWhoishe
