"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 World Watch 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 underlined phrase "picking up" is closest in meaning to ______.

A. starting again B. speeding up

C. improving D. gathering

【2】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

【3】It can be inferred that some day we might not worry about ______.

A. our power supply B. our boat traffic

C. air pollution D. our supply of sea fish

【答案】

【2】D

【3】C

【4】A

【解析】

试题分析:本文介绍了海浪的能量。

【2】D考查词义猜测。pick up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,故选D。

【3】C考查细节理解。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】A考查推理判断。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,所以我们不必担心我们的能源供应,故选A

FIVE WAYS TO KILL YOUR DREAMS

I dedicated the past two years to understanding how people achieve their dreams. When we think about the dreams we have, and the footprint we want to leave in the universe, it is striking to see how big of an overlap there is between the dreams that we have and projects that never happen. So I'm here to talk to you today about five ways how not to follow your dreams.

【1】______

You know the story, right? The tech guy built a mobile app and sold it very fast for a lot of money. You know, the story may seem real, but I bet it's incomplete. If you go investigate further, the guy has done 30 apps before and he has done a master's on the topic, a Ph.D. He has been working on the topic for 20 years. This is really interesting. I myself have a story in Brazil that people think is an overnight success. I come from a humble family, and two weeks before the deadline to apply to MIT, I started the application process. And, voila! I got in. People may think it's an overnight success, but that only worked because for the 17 years prior to that, I took life and education seriously. Your overnight success story is always a result of everything you've done in your life through that moment.

2】____

Constantly, people want to help out, right? All sorts of people: your family, your friends, your business partners, they all have opinions on which path you should take: "And let me tell you, go through this pipe." But whenever you go inside, there are other ways you have to pick as well. And you need to make those decisions yourself. No one else has the perfect answers for your life. And you need to keep picking those decisions, right? The pipes are infinite and you're going to bump your head, and it's a part of the process.

3】______

So when your life is going great, you have put together a great team, and you have growing revenue, and everything is set — time to settle. When I launched my first book, I worked really, really hard to distribute it everywhere in Brazil. With that, over three million people downloaded it, over 50,000 people bought physical copies. When I wrote a sequel, some impact was guaranteed. Even if I did little, sales would be okay. But okay is never okay. When you're growing towards a peak, you need to work harder than ever and find yourself another peak. Maybe if I did little, a couple hundred thousand people would read it, and that's great already. But if I work harder than ever, I can bring this number up to millions. That's why I decided, with my new book, to go to every single state of Brazil. And I can already see a higher peak. There's no time to settle down.

4】_____

I constantly see people saying, "Yes, I had this great idea, but no investor had the vision to invest." "Oh, I created this great product, but the market is so bad, the sales didn't go well." Or, "I can't find good talent; my team is so below expectations." If you have dreams, it's your responsibility to make them happen. Yes, it may be hard to find talent. Yes, the market may be bad. But if no one invested in your idea, if no one bought your product, for sure, there is something there that is your fault. Definitely. You need to get your dreams and make them happen. And no one achieved their goals alone. But if you didn't make them happen, it's your fault and no one else's. Be responsible for your dreams.

5】______

Once I saw an ad, and it was a lot of friends, they were going up a mountain, it was a very high mountain, and it was a lot of work. You could see that they were sweating and this was tough. And they were going up, and they finally made it to the peak. Of course, they decided to celebrate, right? I'm going to celebrate, so, "Yes! We made it, we're at the top!" Two seconds later, one looks at the other and says, "Okay, let's go down." Life is never about the goals themselves. Life is about the journey. Yes, you should enjoy the goals themselves, but people think that you have dreams, and whenever you get to reaching one of those dreams, it's a magical place where happiness will be all around. But achieving a dream is a momentary sensation, and your life is not. The only way to really achieve all of your dreams is to fully enjoy every step of your journey. That's the best way.

The right pair of exercise shoes can do a lot to prevent discomfort and injuries, personal trainers say.Here are some shopping tips:

【1】 Depending on your workout, shoes designed for walking, running, tennis, cross-training or another specialty will provide the best support for your feet.

Shop when you normally exercise.Feet actually get bigger throughout the day, sometimes swelling up as much as a half-size by nighttime. 2

Try them on.Never grab a pair of exercise shoes based only on the size of footwear you normally buy.Bring the type of socks you’d wear to work out and go for a walk through the store.

3 You should be able to spread your toes out comfortably.Make sure there’s about a half-inch of space between them and the front of the shoe.The back should fit snugly (warmly and comfortably) against your heel and not move up and down.If your feet are different sizes, buy based on the larger one.

Talk to an expert.Shoe salesmen and personal trainers can study your stride (步伐) and the shape of your feet. 4

5 Many trainers recommend switching footwear every three to five months, if possible, to maintain(保持)proper cushioning and support.One tip: if you have to tie your shoes very tightly to feel a good amount of support, they may be ready to go.

A.Think about how much you can afford to buy the workout shoes.

B.Consider your type of exercise.

C.Focus on fit.

D.So don’t shop first thing in the morning if you often work out in the evening.

E.Pay more attention to new style shoes

F.Replace worn shoes regularly.

G.Usually they can recommend the best shoes to guard against injuries.
