Sometime early in the next century, human beings will move to Mars．They will live there for about a year, and then will be replaced with another group of pioneers．Building the base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth．

We already know that Mars resembles the earth in many aspects: general size, presence of water, length of day, range of temperatures．These resemblances have caused many people to consider a centuries-long project: to terraform Mars．Terraforming means altering a planet’s surface so that Earth’s life forms can survive there．This concept, previously found only in science fiction is now being seriously considered by scientists．

Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth’s plants and animals in the order in which they developed on Earth．But it will take at least 300 years．

Some people think that such a project is too huge for humans to undertake, but there are very good reasons to make the attempt．The earth now contains some 6 billion people, and no one has any idea of how many humans the earth can support．Our very existence and numbers are threatening many other species．We also have had some experience with terraforming our own planet: altering the landscape, the atmosphere and the climate．Currently terraforming Earth has become a wiser activity as we try to control global warming, air and water pollution, and preserve some natural living places．

Small as the possibility of such a project is, it is not impossible．Even if earth-bound societies come and go in the next 300 years, the project can continue through the work of the Mars settlers without the need for constant backing from the earth．

The future existence of all the people in our world may very well depend upon our ability to terraform Mars．

When John Weston awoke that morning, he remembered that his mother was going into hospital. He hadn’t worked out quite what was wrong with her. He knew, though that she hadn’t been well for some time now, and it had become almost familiar to him to see her eyes narrowed in a sudden attack of pain, and her hand pressing against her heart. Their own doctor, who she had finally gone to for advice, had sent her to an expert who knew all about these things. He had told her that just as soon as there was a bed for her, she would have to come into his hospital where he could look after her himself.

During the weeks since then the pains had come even more frequently, and the narrowed eyes became an almost permanent part of her expression. Always rather sharp, she began losing her temper over little things so that John’s father kept his thoughts to himself more and more. John, as ready as possible to make allowances, tried to think what it would be like to have toothache all the time and how bad-tempered that would make you.

So his mother would go into hospital for a few days. He was going to stay with his Aunt Daisy till she came back, and his father would stay on at home by himself. John’s cousin, Mona, was to come in and make the bed and wash the pots and dust round now and again. That was the arrangement, and John didn’t care much for it. Apart from missing his mother(and he was glad she was going away because they would make her better), he wasn’t very fond of his Aunt Daisy because she was even more bad-tempered than his mother.

1.Mrs Weston went to see her doctor_________.

A.as soon as she realized that something was wrong

B.only after her husband advised her to

C.a long time after the trouble began

D.when John asked what was wrong with her

2.what did Mrs Weston’s own doctor decide to do?

A.he decided to send her to hospital

B.he decided to get an expert to examine her

C.He decided to treat her himself

D.He advised her to wait for a few weeks.

3.how did John react to his mother’s bad temper?

A.he tried to imagine himself in her place.

B.He tried not to notice it.

C.He pretended that he had toothache.

D.He behaved himself as well as possible.

4.John regarded ______as most bad-tempered.

A. his father   B. his mother    C. his cousin Mona   D. his aunt Daisy

【小题1】What would be the best title for this passage?

D
The thing is, my luck’s always been ruined. Just look at my name: Jean. Not Jean Marie, or Jeanine, or Jeanette, or even Jeanne. Just Jean. Did you know in France, they name boys Jean? It’s French for John. And okay, I don’t live in France. But still, I’m basically a girl named John. If I lived in France, anyway.
This is the kind of luck I’ve had since before Mom even filled out my birth certificate. So it wasn’t any big surprise to me when the cab driver didn’t help me with my suitcase. I’d already had to tolerate arriving at the airport to find no one there to greet me, and then got no answer to my many phone calls, asking where my aunt and uncle were. Did they not want me after all? Had they changed their minds? Had they heard about my bad luck—all the way from Iowa—and decided they didn’t want any of it to rub off on them?
So when the cab driver, instead of getting out and helping me with my bags, just pushed a little button so that the trunk (汽车后备箱) popped open a few inches, it wasn’t the worst thing that had ever happened to me. It wasn’t even the worst thing that had happened to me that day.
According to my mom, most brownstones in New York City were originally single-family homes when they were built way back in the 1800s. But now they’ve been divided up into apartments, so that there’s one—or sometimes even two or more families—per floor.
Not Mom’s sister Evelyn’s brownstone, though. Aunt Evelyn and Uncle Ted Gardiner own all four floors of their brownstone. That’s practically one floor per person, since Aunt Evelyn and Uncle Ted only have three kids, my cousins Tory, Teddy, and Alice.
Back home, we just have two floors, but there are seven people living on them. And only one bathroom. Not that I’m complaining. Still, ever since my sister Courtney discovered blow-outs, it’s been pretty frightful at home.
But as tall as my aunt and uncle’s house was, it was really narrow—just three windows across. Still, it was a very pretty townhouse, painted gray. The door was a bright, cheerful yellow. There were yellow flower boxes along the base of each window, flower boxes from which bright red—and obviously newly planted, since it was only the middle of April, and not quite warm enough for them.
It was nice to know that, even in a sophisticated (世故的) city like New York, people still realized how homey and welcoming a box of flowers could be. The sight of those flowers cheered me up a little.
Like maybe Aunt Evelyn and Uncle Ted just forgot I was arriving today, and hadn’t deliberately failed to meet me at the airport because they’d changed their minds about letting me come to stay.
Like everything was going to be all right, after all.
Yeah. With my luck, probably not.
I started up the steps to the front door of 326 East Sixty-Ninth Street, then realized I couldn’t make it with both bags and my violin. Leaving one bag on the sidewalk, I dragged the other up the steps with me. Maybe I took the steps a little too fast, since I nearly tripped and fell flat on my face on the sidewalk. I managed to catch myself at the last moment by grabbing some of the fence the gardeners had put up…
