三、知识点 stop
1）stop 作动词，意为“停止，中断，阻止,阻拦”等意。
例如:The car stopped. 车停了。
The guard stopped me at the gate。 卫兵在大门口将我拦住。
Stop to do sth。停下来去干另一事

2）stop 作名词，意为“停止； 逗留，车站"=station
例如:
I will wait for you at the bus stop. 我会在公共汽车站等你.
四、知识点 hundred
hundred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：There are nine hundred students in our school。 我们学校有900名学生。
拓展:1）hundreds of 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： There are hundreds of people in the restaurant. 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： There are thousands of people are waiting to see the movie star.
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:by bike骑自行车 by car乘小汽车 by bus乘公共汽车
(2) 用“by + 交通路线的位置”来表示交通方式。
例如: by water由水路 by land从陆路 by sea从海路 by air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：She often goes to school on a/her bike.= She often goes to school by bike. 她经常骑自行车上学。
(4） on foot步行。on foot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:She often goes to school on foot. 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：take a train乘火车 take a bus乘公共汽车 take a ship乘船 take a plane乘飞机
注意：“骑自行车”要翻译为“ride a bike”
(2) 用某些动词来表示交通方式。
例如 walk to步行去 drive to开车去 ride to骑车/马去
注意：如果接地点副词here； there； home时,介词to应该省略.
五、 知识点
It takes sb. some time to do sth。
1）It takes sb. some time to do sth。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to do sth.,对这个句式中的时间提问时用how long。
例如:It takes me half an hour to finish my homework every day。
我每天花费半个小时的时间做作业。
How long does it take you from your home to school？
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) doing sth. /on sth。”。
例如：I spend about 3 hours (in） doing /on my homework every day.
我每天花大约三个小时做作业。
六、 知识点 cross
1）cross 作动词， 意为“横过，越过”,指从表面上横过。
例如：They cross the river every day。 他们每天都要过河。
Cross the road， you will see the store。 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：Jesus died on the cross. 耶稣死在十字架上。
He made a cross over his head. 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：They cross the street to go to school every day.
They walk across the street to go to school every day.
七、 知识点
。be afraid…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：I am not afraid。 我不害怕.
句式be afraid是afraid最常用的形式，其常见的用法有：
1)be afraid of
① be afraid of 后跟名词或者代词，意为“害怕某人或某物”。
例如：
Are you afraid of dogs? 你害怕狗吗？
She seems very much afraid of him. 她好像很害怕他。
② be afraid of doing srh。，意为“怕做某事或不敢做某事"。
例如：I'm afraid of telling her。 我不敢告诉她.
He is afraid of jumping. 他不敢跳.
2）be afraid to do sth。意为“害怕做某事或不敢做某事”。
例如： He is afraid to fly in a plane. 他不敢坐飞机。
注意：表示担心会发生某事或某情况,只能用 be afraid of , 而表示“害怕做某事或不敢做某事”时，既可以用be afraid of 也可以用be afraid to。
例如:Don't be afraid to ask (of asking） question。 不要害怕问问题。
He is afraid to go out (of going out) alone at night。 他不敢晚上一个人出去。
3）be afraid that
be afraid that后跟一个完整的句子,意为“担心/恐怕……”。
例如: He is afraid that she will not come. 他担心她不会来。
I am afraid I can’t help you. 恐怕我帮不了你。
在日常口语中, “I'm afraid that…”在很多场合相当于“I'm sorry， 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’m afraid I don't understand. 抱歉，我不明白你的意思。
I’m afraid you are wrong。 (You are wrong, I’m afraid。) 恐怕你错了。
4)在口语中I’m afraid so。 和I’m afraid not.常用作简略答语。
例如: －Is it going to rain tomorrow? 明天会下雨吗？
－I'm afraid so. 恐怕会。
－I'm afraid not。 恐怕不会。
九、知识点 think of
1)think of 意为“认为，想起，考虑”等。后跟名词、代词、动名词等形式。
例如:What are you thinking of ? 你在想什么？
She will smile when she thinks of her good friends. 当她想起她的好朋友时她就会微笑.
2）think of 当“考虑， 对……有某种看法"讲时可以和think about互换。
例如：Don't think of(about）me any more．不要再考虑我。
They’re thinking about(of）buying a new car．他们正在考虑买一辆新车。
常见的think构成的词组还有think over，意为“仔细考虑”。
例如：Think over，and you'll find a way．仔细考虑一下，你就会有办法的。
