3.What is the most popular way to travel in the whole world,not counting a human being's two legs?You say by car?No.Train?Wrong again.Airplane?I'm sorry,but you're not even close.The most popular way of going from one place to another is by bicycle.And it is a surprise to most Americans.After all,we see thousands of cars each day.We don't see nearly as many bikes.
In the United States most bike riders are either young people or adults bicycling for exercise.About nine million bikes are sold in America each year.Nearly three million are sold to adults.The rest are to children.But in the rest of the world,far more people use the bike as their main way of traveling.They ride bikes to work,to school,and to stores.
Bicycles have been around for a long time-about 300 years.You would not like to ride around on those early bikes,though.They didn't have any pedals (腳蹬).The riders had to push along with their feet.And this bike only went straight ahead.There was no way to turn the front wheel.If the rider wanted to change direction,he or she had to get off and move the bicycle.When pedals were put on the front wheels,riding became easier.The most popular kind of bike in the late 1800s had a very high front wheel and a small back wheel.It was a long fall to the ground!
Another problem was that there were no rubber tires (橡膠輪胎).It's no wonder that one bike was called the"Boneshaker."Then in the 1880s,air-filled rubber tires were put on the bicycle's wheels.Since then the bicycle has not changed very much.Of course bikes come in different shapes and colors now,but the main design is still the same.

解答 BCAD
29.B 細(xì)節(jié)題.根據(jù)第一段介紹可知,The most popular way of going from one place to another is by bicycle,在世界上其他地方最受歡迎的交通工具是自行車,故答案為B.
30.C 推理題.根據(jù) 一些信息,如They didn't have any pedals、The riders had to push along with their feet等可知,自行車沒有腳蹬,騎車人必須使勁用腳前行,所以騎車人很難對自行車控制,故選C.
31.A 猜測詞意題.Another problem was that there were no rubber tires,Since then the bicycle has not changed very much這兩句話告訴我們自行車沒有橡膠輪胎,從那時起就沒有發(fā)生變化過,所以該出是說自行車比較舊,故答案為A.
32.D 主旨大意題.根據(jù)全文的內(nèi)容可知,主要介紹自行車是世界上最受歡迎的交通工具,并提到自行車的一些相關(guān)知識,故答案為D.
點評 閱讀這類文章時,也應(yīng)該在整體把握文章結(jié)構(gòu)的前提下,主要注意細(xì)節(jié)信息.細(xì)節(jié)題題干都是相應(yīng)原文的變形(如同義改寫、詞性轉(zhuǎn)換等),因此要找到答案一定要找到題干在原文中的出處,再把原文和選項相比較.做題時,根據(jù)所提問題用尋讀、跳讀的方法可達(dá)到事半功倍的效果.
