1 . What do you plan to do when you retire? Keep working? Get more exercise? Or learn something new? You may put them on hold. There's a chance that, sooner or later, you might have to move further than you were thinking, as far as Mars.
On Thursday, National Geographic will show the first-ever Mars show home, giving earthlings (地球人)an idea of what their life could look like on the Red Planet. In the not-so-distant year of 2037, the igloo-shaped structure could be the home of your future.
It shows a house built using recycled spacecraft parts and Martian soil, called regolith, which has been microwaved into bricks. Some parts of the home are recognizable — a kitchen, a bedroom — but there are fundamental differences that are important to human survival.
As the Martian atmosphere is around one hundredth as thick as the Earth’s, people will need permanent (永久的) shelter from the sun；society will move largely indoors. Most buildings will be connected by underground passages and the houses won't have windows. The homes will have simulated solar lighting, or natural light that has been bent several times. Walls will need to be 10 to 12 feet thick, to protect people from dangerous rays (光线)that can pass through six feet of steel, and a double air-locked entrance to keep the home under proper pressure.
"We don’t think of our houses as things that keep us alive, but on Mars your house will be a survival centre, 99 says Stephen Petranek, author of How We’ll Live on Mars. This is not just the stuff of sci-fi. “10 to 20 years from now there will certainly be people on Mars,” Petranek says.
“We’ve had the technology for 30 years to land people on Mars, but we haven’t had the will, ”Petranek says. But two main factors have “completely swung public attitudes”.
The private companies’ participation has forced government agencies to speed up their game, and influential films such as Gravity and The Martian have caught society’s eye.

2 . Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“I think we are knocking at the door of immortality(永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “I think by 2075 we will see it and that’s a conservative estimate(保守的估计).”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what was possible in the past. “There is a great effort so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. “It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Centre. “At present people who could get to that point are not in good health at all.”

| B．it is possible for humans to live longer in the future |
| C．it is still doubtful how long humans can live |
| D．people can live from 120 to 180 |
| A．a great effort |
| B．the conservative estimate |
| C．the idea of living from 200 to 300 years |
| D．the idea of living beyond the present life span |
| A．No Limit for Human Life |
| B．Living Longer or not |
| C．Science,Technology and Long Living |
| D．Healthy Lifestyle and Long Living |
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
A
Let us suppose it is now about A. D. 2060. Let’s believe it is about forty-four years from now. Of course, things have changed and life is very different.
Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. The hotels are air-conditioned, naturally. In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment of young and old.
What are people eating now? People are still eating food. They haven’t yet started to take on heir (继承) supply of energy directly. They may some day. But many foods now come in pill forms, and the food that goes into the pill continues to come mainly from green plants.
Since there are several times as many people in the world today as there were a hundred years ago, most of our planet’s surface has to be filled. The deserts are irrigated (灌溉) with water and crops are no longer destroyed by pests. The harvest is always good.
Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just pushing a few buttons now and then.
Such would be our life in 2060.
