    "Have you ever been out on a boat and felt it lifted up by a wave? Or have you jumped in the water and felt the rush of energy as waves came over you.'?" asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh. "There is certainly a lot of energy in waves," he said.

    Scientists are working to use that energy to make electricity.  Most waves are created when winds blow across the ocean. "The wind starts out by making little ripples (涟漪), but if they keep on blowing, those ripples get bigger and bigger and turn into waves," Taylor said. "Waves are one of nature's ways of picking up energy and then sending it off on a journey."

    When waves come toward the shore, people can set up dams to block the water and send it through a large wheel called a turbine (涡轮机). The turbine can then power an electrical generator to produce electricity.

    "The resource is huge," said Janet Swain of the Worldwatch Institute. "We will never run out of wave power." Besides, wave energy does not create the same pollution as other energy sources, such as oil or coal. Oceans cover three-quarters of the Earth's surface - that would make wave power seem ideal for creating energy throughout the world, though there are some weak points yet to overcome.

    Swain said that wave power still costs too much money. She also said that its effects on sea animals are still unknown. What is more, wave power could affect fishing and boat traffic.

    Traditional sources of energy like oil and gas may someday run out. "Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is rising rapidly throughout the world," Swain said. In the future when you turn on a light, an ocean wave could be providing the electricity!

1.The writer uses the two questions at the beginning of the passage to _______.

A. test the readers' knowledge about waves

B. draw the readers' attention to the topic

C. show Jamie Taylor's importance

D. invite the readers to answer them

2.The underlined phrase "picking up" (paragraph 2) is closest in meaning to _______.

A. starting again

B. speeding up

C. gathering

D. improving

3.We can make better use of wave energy if we _______.

A. shorten its journey to thousands of homes

B. build more small power stations on the oceans

C. reduce the cost of turning it into electric power

D. quicken the steps of producing electricity

4.It can be inferred that some day we might not worry about ________.

A. air pollution

B. our boat traffic

C. our power supply

D. our supply of sea fish

 

1.B 【详解】这是一套有关写作方法题目,以疑问形式引起读者注意,是一种常见的写作技巧. 2.C 【详解】词义猜测题。pick up在中学里面有很多意义,在这里是“收集”能量意思,这种意思,后面也有提示,sending it off,是递进关系,很容易推断出其意义,另外,我们在高二Charlie Chaplin那一单元已经学过, 不算什么难题。 3.C 【详解】事实判断题。由文章中第五段,Swain said that wave power still costs too much money,可得到答案,其它三个选项文中没有提及. 4.C 【详解】推断题。由第四段第一句话,"The resource is huge," said Janet Swain of the Worldwatch Institute. "We will never run out of wave power. "可以得到答案,never run out of是不会枯竭的能源,是可再生能源。 【备考建议】这是一篇科普文章,是有关能源问题的文章,比较新颖,是常识性问题,所以难度并不大,作为高中生,地理学科等综合学科里面都有涉及,但是也给我们提个醒,我们平时做阅读题时,文章题材方面涉猎面要广,不要只做记叙类的文章。

    Being considered a leader in our society is indeed of high praise. Leadership means power, commands respect and, most important, encourages achievement. Unlike vitamin C, leadership skills can't be easily swallowed down. They must be carefully cultivated.

    Different from popular belief, most good leaders are made, not born. They learn their skills in their everyday lives. But which do they develop? How do they (and how can you) get others to follow?

    Always give credit. Many leaders note that the most efficient way to get a good performance from others is to treat them like heroes. Giving public credit to someone who has earned it is the best leadership technique in the world. It is also an act of generosity (慷慨) that's never forgotten.

    Giving credit is more effective than even the most constructive criticism (批评), which often hurts rather than helps.  Kenneth Blanchard, the author of The One-Minute Manager, agrees. "Catch people doing something right!" he says. Then tell everyone about it.

    Take informed risks. "The best leaders know that taking a risk is not a thoughtless exercise, "says management adviser Marilyn Machlowitz." Sky divers don't go up in an airplane without checking the parachutes (降落伞) beforehand."

    Because the idea of risk also carries with it the possibility of failure, many of us usually wait for others to take charge. But if you want to be a leader, you must learn to fail - and not die a thousand deaths. Pick yourself up and start all over again.

    Encourage enthusiasm. (热情) "When people understand the importance of work, they lend their mental strengths," says Lee Ducat. But when they get excited about the work, all their energy gets poured into the job. That's a great force ! Is this the best way to create excitement? Be enthusiastic yourself - You will be followed by everyone.

1.The underlined word "cultivated" (paragraph 1) roughly means _______.

A. encouraged

B. compared

C. examined

D. developed

2.The part Always give credit tells us that a leader should _______.

A. give helpful criticism

B. regard others as real heroes

C. praise people for their good performances

D. praise everyone

3.To be a good leader, you should _______.

A. not be afraid of any risks

B. think twice before taking risks

C. try to avoid any possible failures

D. know what a thoughtless exercise is

4.Which of the following can be the best title for the passage?

A. Leadership Is of Skills and Techniques

B. Leadership Is Very Important

C. Not Many Can Be Leaders

D. How to Be a Leader

    We have two daughters: Kristen is seven years old and Kelly is four. Last Sunday evening, we invited some people home for dinner. I dressed them nicely for the party, and told them that their job was to join Mommy in answering the door when the bell rang. Mommy would introduce them to the guests, and then they would take the guests' coats upstairs and put them on the bed in the second bedroom.

    The guests arrived. I introduced my two daughters to each of them. The adults were nice and kind and said how lucky we were to have such good kids.

    Each of the guests made a particular fuss over Kelly, the younger one, admiring her dress, her hair and her smile. They said she was a remarkable girl to be carrying coats upstairs at her age.

    I thought to myself that we adults usually make a big "to do" over the younger one because she's the one who seems more easily hurt. We do it with the best of intentions.

    But we seldom think of how it might affect the other child. I was a little worried that Kristen would feel she was being outshined. I was about to serve dinner when I realized that she had been missing for twenty minutes. I ran upstairs and found her in the bedroom, crying.

    I said, "What are you doing, my dear?"

    She turned to me with a sad expression and said, "Mommy, why don't people like me the way they like my sister? Is it because I 'm not pretty? Is that why they don't say nice things about me as much?"

    I tried to explain to her, kissing and hugging her to make her feel better.

    Now, whenever I visit a friend's home, I make it a point to speak to the elder child first.

1.The underlined expression 'make a big "to do" over' (paragraph 4) means _______.

A. show much concern about

B. have a special effect on

C. list jobs to be done for

D. do good things for

2.The guests praised Kelly for carrying coats upstairs because of her _______.

A. beautiful hair

B. pretty clothes

C. lovely smile

D. young age

3.Kristen felt sad and cried because _______.

A.    the guest gave her more coats to carry

B.    she didn't look as pretty as Kelly

C.    the guests praised her sister more than her

D.    her mother didn't introduce her to the guests

4.We can conclude from the passage that _______.

A. parents should pay more attention to the elder children

B. the younger children are usually more easily hurt

C. people usually like the younger children more

D. adults should treat children equally
