    The Three Gorges Dam, the largest dam, is also the largest engineering project on the face of the earth. It aims to make the mother of all floods, the Yangtze River, into a tame river, and to generate(产生) power of 181,200 megawatts(兆瓦特) for Eastern and Central China. It will form a huge, deep water lake, and make it possible for 10,000 ton ocean-going ships to sail 1,500 miles inland from the Pacific to the city of Chongqing, making it one of the world's largest inland ports.

    Construction has already started. The dam will be about 6,860 feet wide and 611 feet high, at a spot called Sandouping near Yichang. It is obvious that such a grand project will do much good. It is the most important to control floods. By building hydropower plants, China will offer much in environmental projection(计划). However, some scientists don't agree to the project. They say Chongqing and dozens of other cities along the river will pollute the reservoir(水库), which will destroy the ecological(生态的) balance and also the sand from upstream will form sand bed. The Three Gorges Dam could be considered when it is finished in 2009, the eighth wonder of the world.

    9. Some scientists fear that ________ when the dam is built.

    A. the ecological balance will be destroyed

    B. large ships will destroy the dam

    C. the Yangtze River will be too shallow

    D. the amount of electricity will not be as much as expected

    10. Which of the following statements is NOT true according to the passage?

    A. China will be able to depend on the Yangtze River for electricity.

    B. Chongqing will become one of the largest inland ports in the world.

    C. The dam won't cause any pollution at all.

    D. The dam will tame the Yangtze River.

    How to Be a Winner

    Sir Steven Redgrave

    Winner of 5 Olympic Gold Medals

    “In 1997 I was found to have developed diabetes (糖尿病). Believing my career was over, I felt extremely low. Then one of the specialists said there was no reason why I should stop training and competing. That was it – the encouragement I needed. I could still be a winner if I believed in myself. I am not saying that it isn’t difficult sometimes. But I wanted to prove to myself that I wasn’t finished yet. Nothing is to stand in my way. ”

    Karen Pickering

    Swimming World Champion

    “I swim 4 hours a day, 6 days a week. I manage that sort of workload by putting it on top of my diary. This is the key to success – you can’t follow a career in any field without being well-organized. List what you believe you can achieve. Trust yourself, write down your goals for the day, however small they are, and you’ll be a step closer to achieving them.”

    Kirsten Best

    Poet & Writer

    “When things are getting hard, a voice inside my head tells me that I can’t achieve something. Then, there are other distractions, such as family or hobbies. The key is to concentrate. When I feel tense, it helps a lot to repeat words such as ‘calm’, ‘peace’ or ‘focus’, either out loud or silently in my mind. It makes me feel more in control and increases my confidence. This is a habit that can become second nature quite easily and is a powerful psychological (心理的) tool.”

    67. What does Sir Steven Redgrave mainly talk about?

    A. Difficulties influenced his career.        B. Specialists offered him medical advice.

     Training helped him defeat his disease.   D. He overcame the shadow of illness to win.

    68. What does Karen Pickering put on top of her diary?

    A. Her training schedule.               B. Her daily happenings.

     Her achievements.                  D. Her sports career.

    69. What does the underlined word “distractions” probably refer to?

    A. Ways that help one to focus.           B. Words that help one to feel less tense.

     Activities that turn one’s attention away.  D. Habits that make it hard for one to relax.

    70. According to the passage, what do the three people have in common?

    It will also have the functions for flood control, power generation and navigation. It will be built from northern and southern banks of the Yangtze, which has been troubled by floods for hundreds of years.

    Launched in 1993, the Three Gorges Project, including the 185-meter-high dam and 26 generators on both banks of the Yangtze, is being built in three phases. The preparations and construction of the first phase were carried out between 1993 and 1997. The Yangtze was dammed at the Three Gorges area for the first time on November 8, 1997. 

    The entire Three Gorges Project is expected to be completed in 2009 and by then, it will be able to generate 84.7 billion kwh of electricity every year.
