How long,take,to drive how long 意为“多长时间”;“It takes sb. some time to do sth. ”是固定句式,意为“做某事花费某人一些时间”。4. three hundred and seventy-five three hundred and seventy-five 意为“375”。5. takes about forty minutesⅢ. 1. How do you come to school?提问交通方式用how;第一人称转换为第二人称;主语变为第二人称you,需借助助动词do完成特殊疑问句。2. How long does it take you to get there? 提问多长时间用how long;形式主语是第三人称单数it,变疑问句时需借助助动词does。3. How far is it from your home to your school? 提问距离用how far。4. Is Peter’s home very far from school? 含有be动词的陈述句变为一般疑问句时,将be动词直接提至主语前。5. Does his father drive him to school?原句的谓语动词是实义动词drives,且主语是第三人称单数,所以在变为一般疑问句时,需借助助动词does。6. Does your father go to work by car?7. He usually takes the train to Shanghai.8. Tom often walks to school.Ⅳ. 1. C 根据答语“我通常七点半到学校”可推断,选项C符合题意。2. D 根据上文问句可推断,此处回答交通方式,选项D符合题意。3. B 根据答语中“骑自行车大约20分钟”可知,选项B符合题意。4. E 根据下文中的“我们可以一起打篮球”可推断,选项E“这个周末骑自行车来我家怎么样?”符合题意。5. A 对于对方的邀请,选项A符合题意。Ⅴ. 1. from句意:我家离学校大约有两英里远。此处所缺的介词是from。2. go/get句意:我通常步行去上学。go to school意为“上学”;get to school意为“到校”,go和get都符合题意。 53. takes 句意:它花费我大约30分钟。“It takes sb. + 时间”意为“花费某人多少时间”。4. bike/bicycle/bus 句意:但是有时我骑自行车/坐公共汽车去那里。表示“自行车”要用bike或bicycle,表示“公共汽车”要用bus。5. me 句意:我只需要花10分钟时间。take为动词,后接人称代词宾格me。6. gets 句意:他每天5点半起床。get up意为“起床”,主语是he,时态是一般现在时,故用第三人称单数gets。7. breakfast 句意:他匆匆吃过早饭,在6点钟去上学。故填breakfast。8. walks 句意:他先步行到公共汽车站。表示“步行”要用walk,主语是he,时态是一般现在时,故用第三人称单数walks。9. minutes 句意:他通常花40分钟的时间到校。故用复数形式minutes。10. best 句意:但我最喜欢步行。like...best意为“最喜欢……”。 Step 9 Homework 1.
