Microsoft founder Bill Gates said that he planned to give away almost all of his vast fortune , largely to the cause of global health , during the course of his lifetime . With an estimated(估计)worth of more than $ 40 billion , according to Forbes , the project will be no small feat (功绩)for Gates .

  A new eight-kilometer road is under construction that links the port area with motorway system. It is expected to carry 20,000 trucks and cars a day, which greatly reduces the overcrowded traffic in the center of the city. As part of the project, two four-kilometer road tunnels are being built below the central area of the city, one for traffic to the north and the other for the traffic to the south. The two tunnels are about 20 meters below the surface and are 12 meters wide, providing for two lanes of traffic in each direction. 

   In the upper part of the tunnel two air-conditioning pipes remove the waste gas of trucks and cars and keep the quality of air inside the tunnel. The lighting is at the top of the tunnel, practically at its highest point. There will also be electric signs at frequent intervals. They show traffic conditions ahead and can be seen clearly by drivers. The wall is made up of four main elements, which include a waterproofing covering and, on the inside of the tunnel, a concrete lining.

   Each tunnel is roughly round and the lower part of the tunnel is somewhat flat. The surface of the road lies on the base, which is made of concrete and steel. The drainage system, just below the road surface on one side, removes any extra liquid, particularly water. In the event of fire, the fire main, which is made of steel, pipes water to many fire hydrant stations at regular intervals along the length of the tunnel. The fire main is at the side of the tunnel and at the level of the road surface. Other systems in the tunnel will include emergency phones.

Each of the tunnels under construction is _____.

   A. eight kilometers long and twenty meters wide

   B. eight kilometers long and six meters wide

C. four kilometers long and twenty meters wide

   D. four kilometers long and six meters wide

Antinuclear Demonstration

       Police fired tear gas and arrested more than 5,000 passively resisting protestors Friday in an attempt to break up the largest antinuclear demonstration ever staged in the United States. More than 135,000 demonstrators confronted police on the construction site of a 1,000-megawatt nuclear power plant scheduled to provide power to most of southern New Hampshire. Organizers of the huge demonstration said, the protest was continuing despite the police actions. More demonstrators were arriving to keep up the pressure on state authorities to cancel the project. The demonstrator had charged that the project was unsafe in the densely populated area, would create thermal pollution in the bay, and had no acceptable means for disposing of its radioactive wasters. The demonstrations would go on until the jails and the courts were so overloaded that the state judicial system would collapse.

       Governor Stanforth Thumper insisted that there would be no reconsideration of the power project and no delay in its construction set for completion in three years. “This project will begin on time and the people of this state will begin to receive its benefits on schedule. Those who break the law in misguided attempts to sabotage the project will be dealt with according to the law,” he said. And police called in reinforcements from all over the state to handle the disturbances.

       The protests began before dawn Friday when several thousand demonstrators broke through police lines around the cordoned-off construction site. They carried placards that read “No Nukes is Good Nukes,” “Sun-power, Not Nuclear Power,” and “Stop Private Profits from Public Peril.” They defied police order to move from the area. Tear gas canisters fired by police failed to dislodge the protestors who had come prepared with their own gas masks or facecloths. Finally gas-masked and helmeted police charged into the crowd to drag off the demonstrators one by one. The protestors did not resist police, but refused to walk away under their own power. Those arrested would be charged with unlawful assembly, trespassing, and disturbing the peace.

What were the demonstrators protesting about?

A Private profits.     B Nuclear Power Station.

C The project of nuclear power construction.   D Public peril.

Who had gas-masks?

A Everybody.    B A part of the protestors.

C Policemen.    D Both B and C.

Which of the following was NOT mentioned as a reason for the demonstration?

A Public transportation.    B Public peril.

C Pollution.             D Disposal of wastes.

With whom were the jails and courts overloaded?

A With prisoners.        B With arrested demonstrators.

C With criminals.        D With protestors.

What is the attitude of Governor Stanforth Thumper toward the power project and the demonstration?

A stubborn.       B insistent.     C insolvable.        D remissible.

An idea that started in Seattle’s public library has spread throughout America and beyond.The concept is simple:help to build a sense of community in a city by getting everyone to read the same book at the same time.

In addition to encouraging reading as a pursuit(追求) to be enjoyed by all,the program allows strangers to communicate by discussing the book on the bus,as well as promoting reading as an experience to be shared in families and schools.The idea came from Seattle librarian Nancy Pearl who launched the “If All of Seattle Read the Same Book” project in 1998.Her original program used author visits,study guides and book discussion groups to bring people together with a book,but the idea has since expanded to many other American cities,and even to Hong Kong.

In Chicago,the mayor appeared on television to announce the choice of To Kill a Mockingbird as the first book in the “One Book,One Chicago”program.As a result,reading clubs and neighborhood groups sprang up around the city.Across the US,stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.

The only problem came up in New York,where local readers could not decide on one book to represent the huge and diverse population.This may show that the idea works best in medium-sized cities or large towns,where a greater sense of unity can be achieved.Or it may show that New Yorkers missed the point,putting all their energy and passion into the choice of the book rather than discussion about a book itself.

Ultimately,as Nancy points out,the level of success is not measured by how many people read a book ,but by how many people are enriched by the process,or have enjoyed speaking to someone with whom they would not otherwise have shared a word.

1.What is the purpose of the project launched by Nancy?

A.To invite authors to guide readers.

B.To encourage people to read and share.

C.To involve people in community service.

D.To promote the friendship between cities.

2.Why was it difficult for New Yorkers to carry out the project?

A.They were too busy to read a book.

B.They came from many different backgrounds.

C.They had little interest in reading.

D.They lacked support from the local government.

3.According to the passage,where would the project be more easily carried out?

A.In large communities with little sense of unity.

B.In large cities where libraries are far from home.

C.In large towns where agreement can be quickly reached.

D.In medium-sized cities with a diverse population.

4.The underlined words “shared a word”in Paragraph 5 probably mean______.

A.discussed the meaning of a word

B.exchanged ideas with each other

C.gained life experience

D.used the same language

5.According to Nancy,the degree of success of the project is judged by____.

A.the number of people who benefit from reading

B.the careful selection of a proper book

C.the growing popularity of the writers

D.the number of books that each person reads
