          分析 Bill有兩個(gè)乒乓球嗎？
          解答 答案：B
          結(jié)合句意"Bill有兩個(gè)乒乓球嗎？"可知該句是一般疑問(wèn)句，結(jié)合語(yǔ)境可知詢(xún)問(wèn)的是客觀事實(shí)故確定為一般現(xiàn)在時(shí)態(tài)，又知謂語(yǔ)動(dòng)詞have是實(shí)義動(dòng)詞，主語(yǔ)Bill是第三人稱(chēng)單數(shù)，變一般疑問(wèn)句助動(dòng)詞用does，句型結(jié)構(gòu)為Does+主語(yǔ)（三單）+謂語(yǔ)（動(dòng)詞原形）+其他，套用結(jié)構(gòu)，故填Does；have故選B
          點(diǎn)評(píng) 助動(dòng)詞，幫助實(shí)義動(dòng)詞構(gòu)成否定句和一般疑問(wèn)句的，要根據(jù)時(shí)態(tài)，人稱(chēng)等選擇正確用法完成試題．

          13．閱讀短文，從各題所給的四個(gè)選項(xiàng)中，選出最佳答案．
          Cars are lots of fun，but they could also be dangerous．We have to be careful when we drive them or ride in them．
          It's always a good idea to put on your seat belt when you're in a car．Why？Think about this example：You put an egg on a skateboard and give it a push．If the skateboard hits a stone，it will stop，but the egg won't．It will fly through the air，hit the ground and break．
          Now，think what would happen if you tied the egg to the skateboard．When the skateboard hits a stone，the egg won't go flying； it will stay safely on the skateboard．
          Volvo，a famous Swedish carmaker，was the first to use seat belts in 1849．
          Air bags are also very important for car safety，because sometimes a seat belt isn't enough．If the car is going really fast and runs into something，seat belts could even hurt the people who wear them．Most new cars have air bags in front of and next to the seats．When a car hits something，its air bags will come out quickly in less than one second to keep the people inside safe．

          66．The passage mainly tells usA．
          A．two important ways to keep safe in cars   
          B．how air bags work to make cars safe

          C．show why it's important to wear a seat belt in a car
          D．tell us what a skateboard is
          68．Seat belts can make us safer because．C
          A．we are interested in them 
          B．they can stop us from hitting other cars
          C．they can help us stay safely on the seats   
          D．they are made of strong materials
          69．Air bags are important for cars becauseB．
          A．they are made of plastic 
          B．they can also help us to keep safe in a car
          C．they can keep cars running slowly 
          D．they are put in front of and next to the seats
          70．Which of the following is TRUE according to this passage？D
          A．It won't be dangerous if there are seat belts or air bags in a car．
          B．Now most of new cars still have only one air bag．
          C．When a car hits something，its air bags will come out a few minutes later．
          D．Volvo was the first to use seat belts．
