The Best Way for Me to Go to SchoolDifferent students go to school in different ways in our school, but I llike to go to school on foot.First, I live near the school, so my home is not far from my school. And it takes me a few minutes to get there. Second, there is a crossing on my way to school, and sometimes the traffic is very busy. I think it is safer to go to school on foot. Third, I think walking is good for my health. It’s a kind of sport and it makes me study better.So in my opinion, the best way to go to school is on foot. What about you?

重点句型解析
1. 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后跟动名词时，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。
③ be afraid of还可以指“担心会发生某事或某情况(但实际上未必会发生)”。例如：
She was afraid of waking her husband. 她怕吵醒她丈夫。
I am afraid of hurting her feelings. 我怕伤害她的感情。
2）be afraid to
be afraid to 后接动词原形，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。
2. 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。
3. How do you get to school？
1）这是由how构成的一个特殊疑问句，用来提问到达某地的方式。句子的结构是“How+ do/does+主语+谓语+其他”。当主语是第三人称单数时，助动词用does，其余人称用do。例如：
How do you go home every day? 你每天怎么回家？
How does your father get to work? 你爸爸怎么去上班？
2）特殊疑问词how 有“如何，怎样，多么”等意，用于询问动作执行的方式、手段、程度。例如：
— How does your father go to work? 你父亲怎样去上班？
— On foot. 步行。
— How do you like China? 你觉得中国怎么样？
— Very much. 非常喜欢。
— How are your parents? 你父母身体怎样？
— Fine. Thank you. 很好，谢谢！
拓展：
how可以和不同的词搭配，构成不同的意思来引导特殊疑问句, 除了我们之前学过的 “how about, how many/ much, how old”等，常见的搭配还有：
how far 用来询问距离，意为“多远”；
how long用于询问时间的长短或者物体的长度意为“多长/久”。例如：
How far is it from your school to the cinema?
从你们学校到电影院有多远？
How long is the river? 那条河有多长？
4. 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。
5. I’m not sure.
1）这句话的意思是“我不是很肯定。/ 我不是很有把握。”；是一个表达对自己所判断的事物没有确切把握时的一个固定套语，它的疑问形式和肯定形式也常用于口语中。例如：
－Are you sure? 你确信吗？
－Yes, I’m sure. 是的，我确信。
2）其中的形容词sure意为“肯定的，确定的”， 可以构成词组make sure, 意为“把事情弄清楚，确信，务使”等；可以直接在句子中作谓语。例如：
Make sure everybody understand you.
要确信每一个人都明白你的意思。
