例1: 字数: 181 难度: level 8.9
Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was ud for. We do know, however, that they existed(存在) over 5,500 years ago in ancient Asia.
The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5,100 years old. Evidence suggests that wheels for transport didn’t become popular for a while, though. This could be becau animals did a perfectly good job of carrying farming tools and humans around.
But it could also be becau of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this diffic
ult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modem road design.
In the mid-1700s, a Frenchman came up with a new design of road---a ba layer(层) of large stones covered with a thin layer of smaller stones. A Scotsman improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs (the central part of a wheel) came into being, followed by the pneumatic tyre(充气轮胎) in 1846. Alloy wheels were invented in 1967, sixty years after it appeared. As the wheel design took off, vehicles got faster and faster.
5. What is the passage mainly about?
A. The beginning of road design. B. The development of transport wheels.
C. The history of public transport. D. The invention of fast-moving vehicles.
【解析自愧弗如是什么意思】根据选项，可以看到中心词各有不同，A是road design, B是transport wheels, C 是public transport，D是fast-moving vehicles 那么可以回到原文中找到对应的词，因为本帐篷怎么画
题在第五题，通常情况下，关键句会在最后一段出现，先看最后一段第一句，In the mid-1700s, a Frenchman came up with a new design of road, 那么此处才提到road design，显然A选项不是正确答案了，再看到这一段的最后一句，As the wheel design took off, vehicles got faster and faster, 随着轮子出现了，交通工具变得越来越快了。一个句子最重点的是主句，由此可见，重点是交通工具越来越快了，似乎在这里提到了轮子的事情，所以D选项也排除了，剩下B和C，回到文章开头，第一段的意思每一种有移动部分的机器都有轮子，然而没有人指的第一代轮子是什么时候发明的或者是用来干什么的。但是他们的确存在在5500多年前，因此可以知道讲的是轮子的发展，所以选择B
例2: 字数: 185 篇章难度: level 4.5
How many hours do you spend in a chair every day? Six hours in the classroom in the daytime and two hours in your study in the evening? A Chines student may say yes.
You don’t need anyone to tell you that sitting too much is not good for your health. It may make you get heavier. It is also bad for your neck and spine(脊椎). A good diet and exerci can’t make your better if you sit too much every day. In other words, sitting is killi
ng us.
狼吃羊的故事Health experts tell us we should stand more, not sit too much. Even small movements like standing to make a phone call, walking over to talk to your classmates, or taking stairs(楼梯) will help. When you are tired becau of too much sitting, why not stand up? Standing up is a very easy thing. Standing up three or four hours in your day at work will be the same as running about 10 marathons(马拉松) a year.
So plea go over to talk to others instead of writing e-mails, ride bicycles instead of taking car to school.页码如何设置
5. This passage is mainly about ____.
A. The Dangers of Sitting Too Much
B. Some Reasons of Getting Heavier
C. Some Advice(建议) on Keeping Exercising
D. A Survey(调查) about Sitting Much
【解析】根据题干，可知本题考察的是主旨题，从结尾最后一段开始看，so plea go over to talk to others instead of writing e-mails, ride bicycles instead of taking car to school, 所以请走过去和人交流而不是写信件，骑自行车去学校，而不是开车。因为开头的so，可见这一段的前面是原因，所以可以猜测是A, the dangers of sitting too much,因为久坐有危险，所以不要写信，而是走过去交流，不要坐车而是骑自行车，为了验证，再看开头，开头的意思是你每天花多少时间坐在椅子上，白天6小时在教室里，晚上2小时在书房里，学生回答是，所以可以看出来这篇文章讲的是久坐的问题，所以选A
