【推荐1】After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered an Earth-sized planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid（液态）water. Scientists think there is a chance that the planet could have life.
The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth. That is about 194 trillion（万亿）kilometres －500 million times farther away from us than the moon.
A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years. A human can’t live that long, but robotic explorers could make the job easier. However, our fastest spacecraft don’t come anywhere near that one-tenth light-speed mark.
At present, scientists don’t know what the surface might be like on Gliese 581g. What they know is that the planet is at the sight distance from its star to have liquid water. It’s also at the right distance to have an atmosphere that could protect the water if it is on the surface.
Although spacecraft won’t be getting there anytime soon, one way to look for life on Gliese 581g is to turn our radio telescopes（望远镜）towards the planet and search for radiation（放射）. By studying the radiation, scientists would find out about the chemicals（化学物质）around the planet and discover it Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea if the planet has life or not. But it’ll probably be many years before we can do this properly.
People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life is just guessing at this point, according to its discoverers.

【推荐2】Do stars only appear at night? The answer is no. Venus (金星) is the only star that can be seen in daytime. It shone at its brightest in the night sky on Feb 17 this year.

Venus is the second planet from the sun. It is the second brightest natural object, behind the earth’s moon, in the night sky. Why is it so bright?

First of all, Venus is the closest planet to the earth. It is also covered by highly reflective (反射的) clouds, which can reflect about 70 percent of the sunlight striking (照射) it, almost twice as much as the earth does. Some people call 2017 the year of Venus, because the planet is at its brightest twice this year. Venus gets brighter when it goes further away from the sun, and nearer to the earth. The brightest moment happened once in February, and will happen again, during daylight, on April 30.

If Venus is so bright and close to us, isn’t it a better choice for human exploration (探索) than Mars? It is closer to the earth than Mars and it’s closer to the earth in size. The closer distance to the sun means solar power (太阳能) would be easier to generate as well.

However, with a temperature of about 465℃ on the surface, Venus is the hottest planet in our solar system!

But scientists never give up. Recently, a team of NASA and Russian scientists created new computer equipment that can stand temperatures of 480℃. It can work under Venus-like conditions (环境) for almost 22 days.

The next step, according to the scientists, is to send a probe (探测器) to Venus by 2025.

1. Which of the following about Venus is NOT true?

A．It’s the only star that can be seen in daylight.	B．It’s the second planet from the sun.
C．It’s the brightest natural object in the night sky.	D．It’s the closest planet to the earth.

2. The underlined word “generate” is similar in meaning to the word “________”.

A．heat

B．produce

C．spread

D．form

3. What makes Venus a worse place for human exploration than Mars?

A．The closer distance to the earth.	B．The similar size to the earth.
C．Too much solar power to use.	D．The extremely high temperature.

4. According to the last two paragraphs, the new computer equipment ________.
a. was created by some UK scientists     b. can stand temperatures of 480℃
c. can work for about 22 days on Venus     d. will be sent to Venus by 2025

【推荐3】Our Future in Space

Many people believe that one day, we may leave the Earth to make our home among the stars. At that time, many people, including you, might live in a space station 200 miles above the Earth.

Space Cities

There will be cities like the one we are living in now.     1     Hundreds, or even thousands, of people will live, work and go to school there.

In fact, we have explored(探索) part of the Moon, and even sent spaceships to the surface of Venus and Mars.     2    

Go into Space

The Moon is full of valuable metals. These metals—if we got them—could be used to build factories and space stations.     3     In that case, more energy can be turned into electricity—for creating comfortable living conditions.

From space, too, we can look down on the Earth and study the atmosphere, its weather, and the influence of air pollution to save it.

At Home in Space

    4     For example, we have to protect ourselves from the ultraviolet(紫外线) because it can give us bad sunburns. Besides, our bones(骨头) will become weaker if we stay out in space for a long time. But we’ll surely find out the solution.

Yet, these risks won’t keep people from going into space.     5     And people will live there with many different interests—medicine, farming, teaching and so on.

The next hundred years will be filled with other worldly adventures, exciting scientific discoveries, and danger, as humans leave the Earth—perhaps forever.

A．But outer space can be a dangerous place.

B．It seems impossible to live in the outer space.

C．Finally, Earth-like environment will be built in space.

D．Without doubt, the research of space has already begun.

E．Also, in space, there is no air to prevent the sun’s energy.

F．Space schools, hospitals, factories and farms will be built.

【推荐1】Do you run away when you see a bee? Many people do. But do you know that bees are very important to humans?     1     They fly around and pollinate (给……授粉) flowers, plants, and trees.

Have you seen or heard a honeybee recently? Bees are disappearing (消失) in many parts of the world.     2     Some North American beekeepers lost many bees. Bees in Italy and Australia are disappearing, too.

That is a serious problem. Can you imagine never eating another strawberry? What about apples and pears?     3     The poorest people always live a bard life when there is not enough food.

This problem will bring a change in other foods besides fresh fruits. Imagine losing your favorite ice cream! Haagen Dazs is a famous ice cream company. The company raises money for honeybees.     4    

Giving money to research is the most important thing humans can do to save the honeybees.   Scientists need money to find out why the bees are disappearing.

But not everyone has money to give often.     5     Tell your friends and family about the problem. Tell your teachers about the disappearing bees too. Maybe your class can write a letter to the government.

A．Honey is good for almost everyone to eat.

B．There are other ways to help the honeybees.

C．Honeybees do more than just make honey.

D．But most people don’t know about this problem.

E．It also teaches visitors how to plant for bees.

F．Without honeybees, food prices will be much higher.

G．Bees always remember to come back the same way as they went.

【推荐3】Plastic straws (吸管) may seem harmless, but they bring dangers to the environment. Because they’re so small, they easily find their way into the ocean. There they can harm animals that try to eat them. They may be small, but the millions of plastic straws that are used and thrown away daily add up to a huge problem. What can you use instead of plastic straws?

Bamboo straws

Fast-growing and plentiful, bamboo is ideal for making straws. Many companies now produce bamboo straws, often without the use of chemicals. Bamboo straws can be washed in a dishwasher or by hand and used again and again. When they do wear out, they break down easily.

Glass straws

Glass straws can also be reused, and if they’re clear, it’s easy to see whether they’re clean or not. They are available in different kinds of lengths, colours and widths, so consumers have many choices.

Bottles that come with straws

Many water bottles come with built-in straws. Although that straw may be made of plastic, you keep it and use it repeatedly. That means it probably won’t end up in ocean any time soon. And it can be cheaper if you choose to fill the bottles with water rather than buying drinks.

No straw

For many drinks, straws aren’t required. People can drink straight out of a cup. And businesses can cut down on the number of straws they use simply by asking people if they want one. Many people seldom notice whether they have a straw or not. Plastic straws are far from the only way to enjoy our favourite drink. Giving them up is an easy way of helping take care of the planet.

1. Which substitutive (替代的) straw is NOT mentioned above?

A．Bamboo straws.	B．Metal straws.

What would the world be like if cars could drive themselves?

Imagine seeing an empty car passing by on its way to pick up its owner, or a car full of passengers who are reading, listening to music or even sleeping. But none of them is worried about the road ahead.

Well, all of these could be the future of driving. There are several companies, for example, Google, working on driverless cars. So far, no Google self-driven car has got a traffic ticket but some of them have been in accident when other cars hit them.

These cars are now still in the testing stages (阶段). If the tests are successful, these electric (电动的), self-driven cars could be put into use very soon. But how is it possible for a car to drive itself? Cars already have many features (特征) allowing them to replace drivers during certain situations. Some features include cars being able to park themselves, or slowdown when they notice other cars close by. They can also control the speed if there are dangerous conditions.

Scientists believe that with the help of wireless signals (无线信号), cameras and GPS, it is possible to create a safe self-driven car very soon.

Usually serious road accidents happen because of careless drivers or dangerous conditions. The self-driven car may be able to stop this. However, some people do not like the idea. They think that technologies can also be mistakes.

1. What’s the main purpose of the first paragraph?

A．To get readers to pay attention to road safety

【推荐2】One way that scientists learn about people is by studying (研究) animals. In this experiment (实验), the scientists are studying the relationship between diet and health.

They are studying the relationship between the amount (数量) of food the mice eat and their health. The mice are in three groups. All three groups are receiving the same healthy food. The first group is eating one cup of food each day, the second group is eating two cups, and the third group is eating three cups.

After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group are a little thinner. But they are more active. Most of the day, they are running, playing with one another. Also, they are living longer. Mice usually live for two years. Most of the mice in this group are still alive (活的) after three years.

The second group of mice is healthy, too. They are active, but not as active as the thinner mice. They are only living about two years.

The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating or sleeping. They are not very active. These mice are living longer than the scientists thought—about a year and a half. But they are not healthy. They are sick more often than the other two groups.
