题目内容

At first sight the planet Mars(火星)does not appear very welcoming to any kind of life. It has very little oxygen and water, the temperature at night is below 50 degrees and winds of 100 miles (161 kilometers)per hour cause severe dust storms. However, the surface of the planet seems to show that water flowed across it at some time in the past, and it is believed that there would be enough ice at the poles to cover the planet with water if it melted. Although there is no life on the Mars now, some scientists think there may have been some form of life a long time ago. At that time, the planet had active volcanoes(火山); the atmosphere was thicker and warmer; and there was water. In fact, in some ways the Mars may have been similar to the Earth, where life exists.

Some people believe that the Mars could support life in the future if the right conditions were produced. The first step would be to warm the planet using certain gases which trap the Sun’s heat in the planet’s atmosphere. With warmth, water and carbon dioxide（二氧化碳）, simple plants could begin to grow. These plants could slowly make the Mars fit to live on. It is judged that the whole process might take between 100, 000 and 200, 000 years. In the meantime, people could begin to live on the planet in a special closed environment. They would provide a lot of useful information about conditions on Mars and the problems connected with living there.

1. According to the passage, the planet Mars has no __________on it.

A．animals B．mountains

C．dust D．winds

2. What is the topic of Paragraph 2?

A．Certain gases should be used to warm Mars.

B．Plants should be grown to make Mars fit to live on.

D．People could live on Mars in a special closed environment.

3. The most suitable title for the passage is __________.

A．No Life on Mars

B．A Study of Mars

C．The Future conditions on Mars

D．The Possibility of Life on Mars

“You go on, and I’ll soon.” I replied.

Doug was for a moment. Then he spoke, “Bud, do you remember the four pine

trees at the side of the road? we get there, we can rest a while and get warm. You just stick your hand down the back of my , keep your head down and hold on.”

As we struggled through the snow, my hand from my brother’s belt and I fell to my knees.

One year ago, I had a special English lesson hold at the railway station. It was quite different from the regular English classes we were familiar to, for we had no textbooks, no blackboard and no fixed seats.

Gathered at the entrance of the station, we told to collect as much English words and sentence as possible there. Curious and excited, we walked around the station and looked everywhere, search for any information in English. Whenever an English word comes into sight, the class would burst into the cheers as if we had discovered a new world. With the Chinese translation and vividly pictures, we could figure out its meaning with ease.

Now, this unforgettable lesson still encourages me to be an active learner where I go.

Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

There are many environment-friendly sport. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.

Ever walked to the shops only to find, once there, you’ve completely forgotten what you went for? Or struggled to remember the name of an old friend? For years we’ve accepted that a forgetful brain is as much a part of aging as wrinkles and gray hair. But now a new book suggests that we’ve got it all wrong.

According to The Secret Life of the Grown-up Brain, by science writer Barbara Strauch, when it comes to the important things, our brains actually get better with age. In fact, she argues that some studies have found that our brain hits its peak between our 40s and 60s — much later than previously thought.

Furthermore, rather than losing many brain cells as we age, we keep them, and even produce new ones well into middle age. For years it’s been assumed that brain, much like the body, declines with age. But the longest, largest study into what happens to people as they age suggests otherwise.

This continuing research has followed 6,000 people since 1956, testing them every seven years. It has found that on average, participants performed better on cognitive (认知的) tests in their 40s and 50s than they had done in their 20s. Specifically, older people did better on tests of vocabulary, verbal memory (how many words you can remember) and problem solving. Where they performed less well was number ability and perceptual speed — how fast you can push a button when ordered. However, with more complex tasks such as problem-solving and language, we are at our best at middle age and beyond. In short, researchers are now coming up with scientific proof that we do get wiser with age.

Neuroscientists are also finding that we are happier with aging. A recent US study found older people were much better at controlling and balancing their emotions. It is thought that when we’re younger we need to focus more on the negative aspects of life in order to learn about the possible dangers in the world, but as we get older we’ve learned our lessons and are aware that we have less time left in life: therefore, it becomes more important for us to be happy.

1.Barbara Strauch probably agrees that ______.

A. the young are better at handling important things

B. people’s brains work best between their 40s and 60s

C. aging leads to the decline of the function of the brain

D. wrinkles and gray hair are the only symbols of aging

2.The continuing research has found older people perform better on ______.

A. perceptual speed B. number ability

C. vocabulary tests D. body balance

3.People are happier with aging because ______.

A. they learn to value the time left

B. they know how to share feelings

C. they cannot focus on negative aspects

D. they do not realize the possible dangers

4.What is the main idea of the passage?

A. People get happier with age.

B. People get wiser with age.

C. People get more forgetful with age.

D. People get more self-aware with age.
