Nowadays, people are very busy. Often, both parents work outside the home. Children are expected to take on more responsibility at home to help their parents. They also have sporting and leisure activities as well as school expectations.
The busyness also adds another factor: the need to use cars to get from one place to another quickly.
Today, society places a lot of emphasis on technology. Computers, DVDs, CDs, television, PlayStations and Xboxes have become major leisure activities, rather than traditional more active pursuits. This has led to a more sedentary lifestyle.
The media provide entertainment and information. (79)Unfortunately, they also promote fast food which fits easily into busy lifestyles. It is much more convenient at times to buy a quick takeaway rather than prepare a meal. The media constantly bombard(轰炸) their audience with "perfect" body images, the need to buy the most fashionable clothes, the most up-to-date computer games, the best places to visit and the best things to do.
Environments vary. We may be exposed to pollution, such as cigarette smoke. This can be harmful to people who suffer from breathing difficulties. (80)Environments where passive smoking is unavoidable make it difficult to lead a healthy life.
Perhaps the important factor influencing healthy lifestyles is motivation, or the desire to be healthy. Any person who wants to be healthy will find a way to be healthy—if he/she is motivated enough!
The passage is mainly about______.
A．benefits of a healthy life style
B．demands of daily life
C．factors affecting a healthy lifestyle
D．a positive approach to healthy living
A.strongly
B.probably
C.wisely
D.properly

Tim Berners-Lee is the man who wrote the software(软件)programme that led to the foundation of the World Wide Web. Britain played an important part in developing the first generation of computers. The parents of Tim Berners-Lee both worked on one of the earliest commercial(商业的)computers and talked about their work at home. As a child he would build models of computers from packaging material. After graduating from Oxford University he went on to the real thing. In the 1980s scientists were already communicating using a primitive version(原始版本)of e-mail. While working at a laboratory in Switzerland, Tim Berners-Lee wrote a programme, which let him store these messages. This gave him another idea: write a programme that will let academics(学术界人士)from across the world share information on a single place. In 1990 he wrote the HTTP(服务程序所用的协议)and HTML(超文本链接标示语言)programmes which form. the basis of the World Wide Web.
The next year his programmes were placed on to the Internet. Everyone was welcome to use them and improve them if they could. Programmers used his codes(编码)to work with different operating systems. New things like web browsers(浏览器)and search engines were developed. Between 1991 and 1994 the number of web pages rose from 10 to 100,000.
In 1994 Tim Berners-Lee formed the newly formed World Wide Web Consortium(协会)，or W3C. More than 200 leading companies and laboratories are represented(代表)by W3C. Together they make sure that everyone can share equally on the web. "The Web can help people understand the way that others live and love and are human. It helps us understand the humanity of people, "he says.
