Humans may not have landed on Mars (火星) just yet, but that isn’t stopping a European company from devising a plan to send four people to the Red Planet within the next few years．This project, called Mars One, aims to send a small group of people to Mars in 2022 and eventually establish a permanent colony on the planet.

“Everything we need to go to Mars exists,” said Mars One co-founder Bas Lansdorp in March 2014．“We have the rockets to send people to Mars, the equipment to land on Mars, the robots to prepare the settlement for humans．For a one-way mission, all the technology exists.” Yet the four astronauts chosen for the trip will be stuck on Mars—forever．And despite Mars One’s thorough planning, there are a number of challenges that may prevent the mission from ever taking place．The biggest road block could be the mission's huge cost ($6 billion)．However, Lansdorp is confident that Mars One will be able to fund the project by selling the broadcast rights for the mission and subsequent experiences living on the planet.

Those broadcast rights will also play a part in helping to select the people who will be sent to Mars．Lansdorp said the company will hold a selection process similar to a reality show．Lansdorp is expecting at least 1 million applications from people around the world．In addition to the cost, several other potential problems could inhibit (阻止) the mission to Mars.

“It’s even more challenging to send people there with life support, with food, with air, with all the other things like books, entertainment, means of communication and of providing for their own resources for a long stay on Mars,” said Adam Baker, senior lecturer in space engineering at Kingston University in London．“The size of the rockets you’d need to do this would be absolutely colossal.”

If humans ever settle on Mars, they will need water. There is just one problem---there seems to be only huge sheets of ice. Luckily, we know how to drill(钻孔） ice for water. Such methods are already used in Antarctica, and researchers now think they could get them to work on the Red Planet, too. The atmosphere of Mars is too dry to make extracting water vapour from it possible. So ice seems the best bet. But the obvious ice sheets are in the unlivable polar ice caps and would be difficult to reach for drilling.

However, in 2018, at the edge of the cliffs, NASA's Mars Reconnaissance Orbiter spotted relatively accessible water ice that is probably at least 130metres thick and covered in just a few metres of rock and dust. These may be the best place to get the water needed for future exploration of the planet.

The drilling techniques needed have already been developed for cold areas on Earth where we need to melt buried ice for water. In the early 1960s the US Army used a type of subsurface reservoir(水库)called Rod Well, in army camps in Greenland. The method works by drilling through the ground into the ice, melting the ice to create a pool, and then pumping water up. By supplying heat continuously, they create a reservoir and a steady water　　　　　　　　 supply. It has been used in remote areas such as the Amundsen-Scott South Pole Station Stephen Hoffman at the Aerospace Corporation in Texas and his colleagues simulated(模拟)how a Rod Well would do on Mars. They found that with the power of 9 kilowatts (千瓦)to melt ice, it could in theory produce about 380 litres of water each day and maintain a reservoir of constant size at the bottom of a borehole(钻孔). That is close to the average daily water use each person in the US, but about 10 times what each astronaut on the International Space Station uses daily.

1.Which of the following can replace the underlined word "extracting" in the first paragraph ?

A.obtaining B.protecting

C.Preventing D.choosing

2.Why does the author mention the Rod Well in Paragraph 3?

A.To explain how water ice is drilled on Mars.

B.To tell about the history of water ice drilling techniques.

C.To prove the importance of water ice drilling techniques

D.To show techniques for drilling water wells in Martian ice exist.

3.On average, how much water does an astronaut on the International Space Station use daily?

A.10 litres B.38 litres

C.160 litres D.380 litres

4.What would be the best title for the text?

A.Preparing to settle on the Red Planet one day.

B.Finding water on the Red Planet for survival.

C.Using some ways to create a livable environment on Mars.

D.Drilling water wells in Martian ice to survive on Mars.

Getting old might not be something that's yet to cross your mind. But aging is going to defeat us one day, so it's something we'd all like to control.

It would be great to have a long, healthy and happy life, and that's why scientists are constantly seeking out what we need to do to achieve it. We all know that regular exercise is good for us. But the latest piece of research might put a spring in your step if you're someone who walks at a fast pace. That's because the speed at which people walk in their 40s is a sign of how much their brains and their bodies are aging.

The BBC's Philippa Roxby writes that tests on 1,000 people found that slower walkers tended to show signs of "accelerated aging”. Their lungs, teeth and immune systems were in worse shape than those walking faster. The study also found not only did slower walkers bodies age more quickly, their faces looked older and they had smaller brains.

This might be seen as a wake-up call for people with a slower pace to work out and get fitter. But it might be too late； researchers say they were able to predict the walking speed of 45-year-olds using the results of intelligence, language and motor (运动)skills tests from when they were aged three. They also suggest that even in early life, there are signs showing which people will have a healthier life.

So, what's the point of knowing that a slower walking pace might mean a smaller brain? Researchers say measuring walking speed at a younger age and understanding what this might mean could be a way of testing treatments to slow human aging.

1.Why do scientists keep on studying?

A.To help people live a better life. B.To achieve their goals.

C.To find ways to stop aging. D.To find out who can live longer.

2.How did the researchers get the result?

A.By analyzing data. B.By doing experiments int he lab.

C.By doing surveys. D.By carrying out tests on people.

3.The findings can be used to .

A.treat certain illnesses B.find ways to slow aging

C.make people work harder D.urge people to walk slowly

4.Where is the text most likely from?

A.A diary. B.A guidebook.

C.A novel. D.A magazine.

Humans have launched themselves into the outer space. They’ve landed on the moon. They’ve built habitable space stations that orbit the Earth. The next giant leap for mankind is to reach another planet – specifically, Mars.

The problem is that it’s no easy task. The planet is 586 times further away from the Earth than the moon, and it’ll take around 180 to 220 days to reach Mars, depending on where each planet is in its orbit. Such long periods in space have suggested many potential health problems, including hormonal changes, skin conditions, and muscle and bone deterioration (损耗).

Here’s where some furry friends come in. A wide range of animals have been in space, from fruit flies and spiders to cats, and dogs. Such experiments began as far back as the late 1940s in first tests to see if living things could withstand the extreme g-force (重力) of a rocket launch.

Mice continue to play a very important part in space experiments, mainly because the animals make excellent test subjects. They’re small, which makes them inexpensive and easy to care for. In addition, their size and short life span make it possible to do the equivalent of several human years of tests in a much shorter time. Finally, because mice are mammals, they share many common characteristics with humans in terms of genetics, biology and behavior.

Astromice have hit the headlines recently, as a team of scientists led by Betty Nusgens, professor of biology at the University of Liege in Belgium, found that the mice suffered a 15 percent thinning of their skin after 91 days aboard the International Space Station (ISS).

This experiment was part of a wider NASA mission (任务) called the Mice Drawer System (MDS). The Italian Space Agency developed the facility, which allows six mice to be housed, monitored, and automatically fed and watered aboard the ISS, among which three survived during the mission.

The mice have participated in 20 separate experiments, to study such effects as osteoporosis (骨质疏松症), anemia (贫血) and heart health.

Results for the 20 experiments are coming in gradually. But it’s clear that mice continue to play an important role in the ongoing quest to conquer the final frontier.

1.We can infer from Paragraphs 2-3 that ______.

A. Mars is the farthest planet away from Earth discovered so far

B. the journey to Mars could put humans’ health at risk

C. it was in the late 1940s that animals were first sent to the ISS

D. animals that have been sent into space have mostly survived

2.The underlined word “withstand” in Para.3 means _________.

A.set up　　 　　 B. hold up

C. work out　　 D. come across

3.According to Betty Nusgens and her team, the mice aboard the ISS ______.

A. suffered the loss of part of their skin

B. all survived for the duration of the mission

C. were fed and watered by the astronauts

D. participated in 20 experiments that made great breakthroughs

4. The main purpose of the article is to _____.

A. describe the role mice play in scientific research

B. report on the results of the Mice Drawer System

C. analyze how mice could pave the way to Mars

D. change people’s traditional attitudes toward mice
