Question

【題目】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.

【1】The 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

【2】From 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

【3】According 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.

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

A.a loud noiseB.a government job

C.a rapid increaseD.a computer program

Answer 1

【答案】

【1】B

【2】D

【3】A

【4】C

【解析】

文章主要講解了互聯(lián)網(wǎng)的發(fā)展史以及互聯(lián)網(wǎng)信息的提取。第一二兩段主要介紹互聯(lián)網(wǎng)的發(fā)展史，第三四兩段介紹互聯(lián)網(wǎng)是收集和發(fā)送信息的。

【1】細節(jié)理解。文章第一段最后兩句句“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.”可知互聯(lián)網(wǎng)運用越來越廣泛。故選B。

【2】細節(jié)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的功能是計算用戶有多少。故選D。

【3】推理判斷。文章中的圖表題。A選項的意思是在2000年，有少數(shù)的人在用電腦，通過圖表可知，2000年有少于5億的用戶，和后面幾年對比，2000年的人是最少的。 B選項說2000年電腦用戶超過5億，但圖表中2000年的用戶少于5億。C選項2000年到2008年的用戶變少了，通過圖表可知，2000年～2005年，用戶的數(shù)量，總體是呈現(xiàn)上升趨勢的，增長了600million左右， 2005年～2008年 增長了700左右，所以2000年～2005年增速未變緩慢，所以D是錯的。故選A。

【4】推理判斷。文章主要講解的是網(wǎng)絡的發(fā)展史。從1969年只有4臺計算機到1989年超過80000臺。用戶人數(shù)從2000年少于500 million 到2008年超過1500 million，可以得出網(wǎng)絡發(fā)展速度非�？�，所以選C。

做題時首先對原文材料迅速瀏覽，掌握全文的主旨大意．其次，細讀題材，各個擊破．掌握全文的大意之后，細細閱讀材料后的問題，弄清每題要求后，帶著問題，再回到原文中去尋找、捕獲有關信息。如第2小題，細節(jié)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的功能是計算用戶有多少。故選D。
