【题目】Internet Boom

Today the Internet is widely used in homes, schools, and businesses around the world. However, that hasn’t always been the case. The Internet was first developed in the 1960s and 1970s by U.S. government scientists as a way of sharing information. The earliest Internet was called ARPAnet. In 1969, only four computers were connected to the ARPAnet. Just 20 years later, though, as computers became more commonly developed, over 80,000 computers were connected.

Use of the Internet has continued to grow rapidly. Experts think that about 1% of the world’s population used the Internet in 1996. By 2008, that percentage grew to nearly 24%.

How do scientists count more than 1 billion users? Programs called Web Crawlers look through the Internet to see how many people are using the Internet and which pages they are visiting. They also make copies of webpages, which are stored by search engines. Web Crawlers work and collect information once they are started. These programs are sometimes called “spiders” because they “crawl” around the Web.

These programs collect and send information 24 hours a day. So if everyone stops using the Internet for one day, the Internet will still be a pretty busy place. Even when people are not online, these programs travel the Internet.

1The information in the first paragraph shows the idea that the Internet ____.

A.is available mainly in the United States

B.has a wider use today than it did in the past

C.is seldom used by people in other countries

D.is used mainly by government scientists today

2From the third paragraph, we can know that scientists use Web Crawlers to ____.

A.clean the webB.catch the spiders

C.find the InternetD.count the users

3According to the chart, which one of the statements is TRUE?

A.There were much fewer people who used Internet in 2000.

B.There were more than 500 million Internet users in 2000.

C.The number of Internet users became less from 2000 to 2008.

D.Use of the Internet grows slowly between 2000 and 2005.

4The underlined word “Boom” in the title means ____.

A.a loud noiseB.a government job

C.a rapid increaseD.a computer program

【解析】

文章主要讲解了互联网的发展史以及互联网信息的提取。第一二两段主要介绍互联网的发展史,第三四两段介绍互联网是收集和发送信息的。

1细节理解。文章第一段最后两句句“In 1969, only four computers were connected to the ARPAnet. Just 20 years later, though, as computers became more commonly developed, over 80,000 computers were connect.”可知互联网运用越来越广泛。故选B

2细节理解。文章第三段的第二句“Programs called Web Crawlers look through the Internet to see how many people are using the Internet and which pages they are visiting.”可知Web Crawlers的功能是计算用户有多少。故选D

3推理判断。文章中的图表题。A选项的意思是在2000年,有少数的人在用电脑,通过图表可知,2000年有少于5亿的用户,和后面几年对比,2000年的人是最少的。 B选项说2000年电脑用户超过5亿,但图表中2000年的用户少于5亿。C选项2000年到2008年的用户变少了,通过图表可知,2000年~2005年,用户的数量,总体是呈现上升趋势的,增长了600million左右, 2005年~2008 增长了700左右,所以2000年~2005年增速未变缓慢,所以D是错的。故选A

4推理判断。文章主要讲解的是网络的发展史。从1969年只有4台计算机到1989年超过80000台。用户人数从2000年少于500 million 2008年超过1500 million,可以得出网络发展速度非常快,所以选C

做题时首先对原文材料迅速浏览,掌握全文的主旨大意.其次,细读题材,各个击破.掌握全文的大意之后,细细阅读材料后的问题,弄清每题要求后,带着问题,再回到原文中去寻找、捕获有关信息。如第2小题,细节理解。文章第三段的第二句“Programs called Web Crawlers look through the Internet to see how many people are using the Internet and which pages they are visiting.”可知Web Crawlers的功能是计算用户有多少。故选D
