Are we alone in space? Is the Earth the only planet that has life?     1     Now we may get one step closer to the answers.

On Feb. 22nd, NASA said they found seven Earth-like planets.     2     The planets go around a dwarf star（矮星）called Trappist-1. It is much smaller and cooler than our sun. They are about 39 light-years（光年）from the Earth.     3     But scientists say it’s a little close.

    4     If you lived on one of them, you could possibly see the clouds around the next planet. More importantly, three of the planets are at the perfect distance（距离）from the Sun.     5     If there is liquid water（液态水）, there could be life.

For scientists, the finding is not an end. Next, they will try to find out if the planets have atmospheres（大气层）.

A．It means there could be liquid water on them.

B．That seems too far away from us.

C．These are big questions in the science world.

D．The seven planets are very close to one another.

E．They all nearly have the same size as Earth.

【推荐2】Are we humans alone in space? Scientists have been working on this question for a long time. And recently, new discoveries offer more hope that some form of life existed on Mars in the past, and perhaps is still there at present.

According to a new report in the book Science, the Mars Explorer Curiosity has found more methane (甲烷) in the Martian air. It might suggest the possibility of life.

During the last 20 months, Curiosity has found methane many times, and four of them, it tested at a level 10 times higher than usual. “It’s a great increase,” said Christopher Webster, the lead scientist.

This new finding has made a big change. In September 2013, Curiosity found almost no sign of methane on Mars. Just weeks later, however, the explorer picked up the gas.

Methane is also found in Earth’s air, and comes from animal and plant life, as well as from the environment itself. If there’s methane in Mars’ air, where is it coming from? Scientists aren’t sure.

“There are many possible sources, such as actions between water and rock,” guessed Sushil, a scientist of the Curiosity team.

But the scientists have left the possibility open that microbes (微生物) could be the methane’s source. Also, for the first time, Curiosity found other organisms (有机物) in the rocks of Mars. Organisms are thought to be the basis to form life. Scientists aren’t sure where these organisms come from. They could either have formed on Mars or landed on Mars by meteorites (陨石).

For the next three years, Curiosity will keep looking for more organisms in rocks and exploring Mars.

1. Where did Curiosity recently find methane?

A．In the Martian air.

B．In the air on Earth.

C．In rocks on Mars.

D．In the water on Mars.

2. Scientists predict that there might be life on Mars because ________.

A．methane is a sign of life	B．astronauts sent to Mars have seen signs of life
C．the Mars Explorer has taken some photos of animals	D．the environment on Mars is similar to that on Earth

3. Scientists think ________ may be the basis to form life.

A．rocks

B．meteorites

C．methane

D．organisms

4. From the last two paragraphs, we learn that ________.

A．scientists are sure to have found life on Mars	B．methane is the basis to form life
C．there is more to learn about Mars	D．there are no rocks and water on Mars

【推荐3】①Most people have a place to call home on Earth. What about in outer space? The International Space Station(ISS) became our first “home” in space in 2000. It welcomed its first crew(队) that year, paving the way(铺平道路) for 20 years of future research.

②“You just have this impression that we’re all citizens(公民) of not a country, but of the planet,” former NASA astronaut Scott Kelly told National Geographic about working in ISS. “We’re all in this thing called humanity(人类) together.”

③Over the past 20 years, the ISS has mainly been used as a science lab, hosting 241 people from 19 countries, according to NASA. They have gone on spacewalks, done research on how space affects the human body, and even grown plants in space.

④ ▲ . For example, the station’s water purification(净化) technology has been used in poor areas to provide clean drinking water. The station also helps to warn us of natural disasters(灾难), such as earthquakes.

⑤However, after being our home in space for over 7,000 days, the station is starting to get old. It has leaked(泄漏) air a few times. Scientists think that the station can keep working until 2024. After that, scientists will bring it down to Earth. It is believed that Earth’s atmosphere(大气) will burn up most of the station. Other debris(残骸) will fall into the Pacific Ocean.

⑥In the future, space will be home to more stations like the ISS. NASA is building a space station that is smaller than the ISS near the moon. Also, China will have its own space station up in 2022.

1. What did Scott Kelly feel about his work in space?

A．Comfortable

B．Proud

C．Bored

D．Lonely

2. The astronauts have _______ while working in ISS.

(a. gone on spacewalks        b. provide clean water for poor areas       c. stopped earthquakes       

d. learned how space affects the human body            e. grown plants )

A．abc

B．abd

C．ade

D．bde

3. Which of the following sentences can be put in the ▲ .

A．We don’t know why we call the ISS our first “home”.

B．The station has also done something good to us on earth.

C．You want to know who has visited the ISS over the years.

D．People may wonder how scientists live on the station.

4. If we put the passage into three parts, which of the following is the best?
(Para. 1=① Para. 2= ② Para. 3=④ Para. 4=④ Para. 5=⑤ Para. 6=⑥)

【推荐1】You get up in the morning and look into the mirror. Your face is not likely to change and stays young-looking. In 2035, medical science is better than ever. Many people of your age could live to be 150, so at 40, you’re not old at all. And your parents just had an anti-aging nanotechnology treatment. Now, all three of you look the same age!

You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” include particles, which are very small in size and can be used to change your clothes’ color or pattern.

You walk into the kitchen. You get the milk, but a voice says, “You shouldn’t drink that!” Your fridge has read the FRID chip, a piece of electronic equipment, on the milk bottle, and it knows the milk is old. In 2035, every food item in the supermarket has an FRID chip.

It’s time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeves. Nano-sized “smart technology(科技)” is all around you. “Your whole body and everything around you will become part of the same network,” says scientist Ampy Buchholz.

So will all these come true? For new technology to succeed, says scientist Andrew Zolli, “it has to be so much better that it replaces what we have already.” The Internet is one example—what will be the next?

1. According to the passage, what will happen in 2035?

A．People will live to be 150.

B．Clothes will be much cheaper.

C．Cars can change colours themselves.

D．Food can stay fresh for a longer time.

2. What will come true according to scientist Ampy Buchholz?

A．Technology can be very dangerous.

B．Technology can replace what we have already.

C．Technology can make people nervous.

D．Technology can be part of our lives.

3. What is the best title for the passage?

A．Why will Everyday Life be Changed?	B．How will We Live in 2035?
C．When will Smart Technology be Used?	D．What will We Eat and Wear in 2035?
