同义句：What __________________________________________________?
练习：你认为长城怎么样？
a._________________________________b.______________________________________
2. But I heard that the traffic there was terrible and almost everyone drove too fast.




点拨：hear---听见+宾语，听说+宾语从句 拓展：hear of…---听说 hear from…---收到…的来信
思考：2句中的heard在此意思是__________, 后面是that引导的___________________
巩固：a. I have never heard of the singer from Africa.
译：____________________________________________________
b. Helen couldn’t hear anything because of her illness.
译：____________________________________________________
c. We haven’t heard from him for a long time.
译：____________________________________________________
点拨：the traffic there---那儿的交通，there在此做the traffic的后置定语
练习：the food there___________________ 那儿的生活______________________
北京的天气______________________
点拨：drove too fast---开车太快 总结：我们学过的表示“快”的单词有：fast, quick和rapid
区别： 1)表示人的动作之迅速，三者都可用，有时可换用。
如： a fast / rapid / quick worker 一个____________的工人
a fast / rapid, quick / typist 一个___________的打字员
2) fast 表示“快”，侧重指速度方面。
如：a.She ran as fast as she could. 译：_____________________________________________
b.You are reading too fast for me to follow. 译：_________________________________
注意：询问速度或表示钟表走得快等，通常用 fast。
如：a. _________ ___________is the fish swimming? --- 这鱼游得有多快?
b. My watch is________ _________ _______. --- 我的表快 5 分钟。
　　　3) quick 通常表示某一动作来得突然或时间持续很短，有时还含有匆忙之意(但通常不指动作的频率)。
如：a.He gave her a quick kiss. 译：_________________________________________
b. He had a quick look at it. 译：_________________________________________
c.She _______ ____ _______ ___________ and rushed off to work. ---
她匆匆吃了早餐就赶去上班。
注意：催人快做(快走等)，通常用 quick。 如：快点！--- ________________
4) rapid 比另外两词要稍正式些，通常指突然或急速(且连续不断)的动作。
如：a. He asked questions in rapid succession（连续）.--- 他连珠炮似地发问。
另外: rapid 还有一个特殊用法，即指一种有益的高速度(相比之下，fast 和 quick 有时指无益的急速)。
如：He has made rapid progress in English recently.
译：__________________________________________________________
3. You will get used to it very soon if you come.
译：_________________________________________点拨：get(be) used to---习惯于，to在这里是介词
区别：used to---过去常常…, to在这里是不定式符号
练习：a.我们将很快习惯北京的生活。We ________ soon ________ _______ ______ the life ______ _________.
b.他已经习惯步行上班了。He _______ already ________ ________ _______ _________ to work.
c.他过去常常开车上班。He ________ ________ __________ by car.
4. They used to be, but the city has improved a lot since I came here a few years ago.
译：_____________________________________________________________________
思考：since在句子中做_______词，后面只能使用________________时态
