Steven Jobs was born on February 24,1955，in San Francisco，California，and was adopted by Paul and Clara Jobs.In 1961 the family moved to Mountain View, California.At that time people started to refer to the area as “Silicon Valley”．

As a child, Jobs preferred doing things by himself, not interested in team sports or other group activities.He enrolled in the Hewlett?Packard Explorer Club. There he saw his first computer at the age of twelve. He was very impressed, and knew right away that he wanted to work with computers.

At that time almost all computers were so large that one could fill a room, and so costly that individuals could not afford to buy them.Advances in electronics, however, meant that the parts of a computer were getting smaller and the power of the computer was increasing.

By 1980 the personal computer era was well underway.Apple was continually forced to improve its products to remain ahead, as more competitors entered the marketplace. Apple introduced the Apple Ⅲ， but the new model suffered technical and marketing problems.It was removed from the market.

Early in 1983 Jobs unveiled the Lisa.It did not sell well，however, because it was more expensive than personal computers sold by competitors.Apple's biggest competitor was International Business Machines (IBM). By 1983 it was estimated that Apple had lost half of its market share ( part of an industry's sales that a specific company has) to IBM.

In 1984 Apple introduced a revolutionary new model, the Macintosh.The Macintosh did not sell well to businesses，however.It lacked features other personal computers had, such as a corresponding high quality printer. The failure of the Macintosh signaled the beginning of Jobs's downfall at Apple.

Late in 1988 the NeXT computer was introduced, aimed at the educational market.The product was very user?friendly，and had a fast processing speed, excellent graphics displays，and an outstanding sound system.Despite the warm reception，however, the NeXT machine never caught on. It was too costly, had a black?and?white screen, and could not be linked to other computers or run common software.

The United States is not part of the Kyoto Protocol.But since 2005 more than 1,000 mayors across the country have agreed to sign their own version of the protocol.

It is called the United States Conference of Mayors' Climate Protection Agreement.Local leaders have agreed to follow the suggestions of the Kyoto Protocol in their communities.They have also agreed to urge state and federal governments to follow these suggestions.One goal is to reduce air pollution to the 1990 levels by 2012.

A “green” city might work on several kinds of environmental goals and programs.These include air quality，reducing electricity use, green building, public health, the reuse of materials, water quality and clean transportation.

The Natural Resources Defense Council works to protect the environment through action, law and science.One of its online projects is called Smarter Cities, which lists some cities that have made important environmental steps.

Washington，D.C.is also a leading city for green roofs，with over 92,000 square meters of green rooftops.The city also launched a program called “Skip the Bag，Save the River.”Stores charge people a five?cent tax for using plastic or paper shopping bags instead of reusable bags.Money from the tax will be used to clean up a local river.

New York City is using water as a renewable energy source.For several years, the city has experimented with water in the East River to create energy.Officials operating the program recently asked for permission to put into place 30 river turbine devices.

The people of Portland, Oregon are among the top recyclers in the nation.People living there recycle over half of the waste they throw out.The city has also worked to provide green transportation by providing safe bike paths and free parking spaces where electric cars can get recharged.

In Oakland, California, you can ride on one of several public hydrogen?powered(氢气作燃料的) buses.These buses release zero pollution into the air.However，they cost about five times more than common buses.
