The United States space agency, NASA. says its Mars exploration vehicle recently recorded a high level of methane (甲烷) gas on the planet. The discovery is exciting because the presence of methane gas could support the case for life on Mars.

NASA's Curiosity vehicle recently recoded the largest level of methane ever measured during its seven-year Mars mission.

Methane has no color or smell. A special instrument on Curiosity's Man Science Laboratory recorded the increased gas level. The device measures levels of chemical elements and gases in the Marian atmosphere. In addition to methane, the instrument can record levels of water and carbon dioxide.

Nearly all the methane gas found in Earth's atmosphere is produced by living thing. It usually comes from animal and plant life. But it can also be formed by geological(地质的) processes, such as interactions. between rocks and water.

It was not the first time Curiosity had found methane gas in the Martian atmosphere. About a year ago, NASA announced that Curiosity had discovered sharp seasonal increases in the gas. This time, NASA said the measured methane gas level was clearly larger than any others observed in the past. "It's exciting because microbial (微生物的) life is an important source of methane on Earth," NASA said in a statement announcing the discovery.

However, Curiosity's team carried out a follow-up methane experiment that showed a sharp drop in levels of the gas. That number was "close to the background levels Curiosity sees all the time." NASA said. The rise and fall of the methane gas levels left NASA scientists with more questions than answers.

"The methane mystery continues," said Ashwin Vasavada. Curiosity's project scientist, "We're more motivated than ever to keep measuring and put our brains together to figure out how methane behaves in the Marian atmosphere."

1.What do we know about methane go?

A.It is a must to living things. B.It can be found everywhere.

B.There will be more methane gas on Mars.

C.There is no progress in the 7 year's research.

D.The level of methane gas on Mars is not stable.

3.What does the discovery mean in NASA's view?

A.There may exist life on Mars.

B.Methane gas on Mars has a sudden increase.

C.The mystery about Mars will be solved soon.

D.They're known how methane as is formed on Mans.

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, 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 the Mars and the problems connected with living there.

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

A. winds                            B. dust

C. mountains                        D. animals

2.It is believed that on the Mars now　　.

A. there is a large amount of ice at the poles

B. there is a thicker and warmer atmosphere

C. there are some kinds of simple plants

D. there are many active volcanoes

3. What is the topic of Paragraph 2?

A. Certain gases should be used to warm the Mars.

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

C. The Mars could support life on right conditions in the future.

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

4. The most suitable title for the passage is　　.

A. No Life on the Mars

B. Study of the Mars

C. The Possibility of Life on the Mars

D. Future Conditions on the Mars

NASA has a new job listing, and it’s no joke. The US space agency is looking for a “joker” to join their planned mission to Mars.

A mission to Mars is no laughing matter. On average, the red planet is 140 million miles (225 million kilometers) away from Earth. A trip there would take around eight months in a small spacecraft. And Mars has a communications delay of 20 minutes. This means that astronauts will have to wait 20 minutes for a reply, when an emergency happens.

“When you’re living with others in a confined space for a long period of time, such as on a mission to Mars, problems are likely to occur,” Jeffrey Johnson, a scientist at the University of Florida, told the Guardian.

This is probably why NASA wants an astronaut with a sense of humor. “These are people that have the ability to pull everyone together,” Johnson said.

In stressful situations, perhaps humor is a way to know we aren’t alone. By laughing together, we share our stress. Then we can focus on our jobs instead of just worrying.

There are other examples of team “clowns”. One example is the journey to the South Pole led by Norwegian explorer Roald Amundsen. It was a difficult journey, full of danger. Adolf Lindstrom, a cook at Amundsen’s team, was a “clown”. He made people laugh through the whole journey. Amundsen later wrote that Lindstrom was the most valuable member of the team.

But if you’re hoping that your favorite TV comedian will fly to Mars, that probably won’t happen.

“Being funny won’t be enough to land somebody the job,” Johnson said. “They also need to be an excellent scientist and engineer.”

Besides, they must be in top physical condition.

1.What is NASA’s new job listing?

A. A funny engineer. B. A talented clown.

C. A good cook. D. A popular comedian.

2.What does “a confined space” in Paragraph 3 refer to?

A. A crowded space. B. An empty space.

C. An open space. D. A small space.

3.How does the author think humor can help astronauts?

A. It can stop them from feeling worried.

B. It can encourage teamwork on a mission.

C. It can help them feel less homesick.

D. It can help them know themselves better.

4.What point does the author want to make with the example of the cook?

A. What explorers eat on their journey is very important.

B. An amateur can play a more important role than a professional.

C. Humorous people can cheer people up in difficult situations.

D. A mission to Mars is more difficult than a journey to the South Pole.

5.What could be the best title of the passage?

A. Keeping the Spirits Up

B. A Mission to Mars

C. A New Job Listing of NASA

D. Humorous Astronauts in NASA
