【1】Sometime early in the next century, human beings will move into habitats on Mars. They will live there for about a year, and then will be replaced with another set of pioneers. The establishment of this base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth.
【2】We already know that Mars is like the earth in many ways: general size; presence of water; length of day; range of temperatures. These similarities have caused many people to consider a century-long project: to terraform Mars. Terraforming means changing 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.
【3】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.
【4】Some people think that such a project is too huge for humans to accomplish, but there are very good reasons to make the attempt. The earth now contains some 7 billion people, and no one knows how many humans the earth can support. Our very existence and numbers are threatening many other species with extinction. We also have had some experience with terraforming our own planet: changing the landscape, the atmosphere and the climate. At present, we are aware of the importance of terraforming the earth as we try to control global warming, air and water pollution, and protect some natural habitats.
【5】While the future of such a project is daunting(令人生畏的), 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 earth.
【6】The future existence of humanity may very well depend on our ability to terraform Mars.

[1] Nowadays the cost of a new car has fallen in real terms so that it is cheaper than ever to own one, and better road conditions have also attracted more drivers. The result is overcrowding on the road system, which is one of the problems the local governments are faced with.
[2] When people travel to other towns, the problem might be relieved by getting them to park outside the town. Buses could be provided to take them into the centre. These Park and Ride projects are increasingly popular in the UK. At Southerton, for example, a council-funded project led to a 15% drop in city centre traffic over five months.
[3] What the council found, though, was that the project proved somewhat unpopular with shop owners in the area outside the centre. Many of their shops relied on passing car drivers for some of their trade. As the number of people driving past dropped, so did their incomes.
[4] Making car driving expensive is another way of ____________. Road taxes tend to mean that people use their cars less. Fining drivers who are in areas where cars have been banned can also tend to encourage them to leave their cars behind.
[5] However, one thing has to be got right for any solution to succeed. If we expect people to give up the habit of driving, we must give them an alternative they can rely on. Constant delays, unannounced changes to the timetable and sudden cancellations all discourage people from using public transport. People will only see it as a real choice if the buses and trains are on time.
小題1:What causes overcrowding on the road system according to Paragraph 1? (no more than 12 words)
_______________________________________________________________________________
小題2:What should people do when traveling to other towns according to the Park and Ride projects? (no more than 10 words)

[1]Your vocabulary refers to the words in a language you are familiar with．Your active vocabulary contains the words you understand and use in speech and in print，and your passive vocabulary includes the words you do not use but understand．Although children learn more new words than adults，the vocabulary of an adult is not fixed and can be increased．Improve your language skills with daily exposure to new words，their pronunciations and meanings．

[1] People of all ages and races can serve as volunteers. They work in various organizations without pay. Volunteering improves your life and the lives of others. You can meet new people and make a positive difference in the world.
[2] Volunteers generally work with others either as part of a team completing a project or caring for other people such as patients in a nursing home or helping children through an organization such as Big Brothers, Big Sisters. Volunteers should be generally cheerful and easy to work with and have a positive attitude even if things are not satisfactory in their own lives.
[3] Some volunteers organize events or groups of people to work on various projects. Without their good organizational skills, these projects might not happen. For example, if you’re the Parent-Teacher Association President for your school, you will be responsible for organizing the individual committees in your school. If you have good organizational skills, volunteering will become less stressful and you can give back to your community in the way you intended.
[4] Volunteers have to be willing to devote a certain amount of hours each week or month depending on the situation. It is necessary for them to go through testing or training before they begin volunteering. The best volunteers do what they say they’re going to do and show up when they say they’re going to be there unless there are situations beyond their control.
[5] Good volunteers see the good in others, whether it’s the people they’re working with or the people they’re serving. These volunteers generally go beyond what they’re asked to do because they want to get to know the people they’re serving. They go beyond surface relationships by remembering names, information and stories told to them. Volunteers that are healthy and well-balanced will bring that feeling to the environment, and the people they’re helping will be affected.

閱讀下面短文，并按照題目要求用英語回答問題（請注意問題后詞數(shù)要求）。
Poverty today is a major global issue. Although there are all kinds of definitions used to explain it, in simple words, it means the inability of a person to even get his basic needs of food, shelter, clothing, safe drinking water, health and education. Poverty can be found in each and every corner of the world, although the causes may differ from country to country. Given below are the main causes of poverty in the world today.
Overpopulation is one of the main causes behind the threatening of poverty on an individual level as well as a social level. This is simple math: If there are more mouths to feed and less income, definitely much will remain poor.
Another theory which is used as an explanation for poverty is lack of education. If you look at any of the underdeveloped countries, you will find that the level of education there is very low. Lack of education means lack of employment opportunities, thus leading to unemployment coupled with poverty in the future.
Moving away from one’s own homeland to another city or country in search of employment leads to poverty too. It may take these people a lot of time to find jobs. Meanwhile, they live in bad conditions. The cost of living in the city or country is most of the time too high for them.
There may be other causes of poverty like the change in business. For example, in America, a couple of decades ago, heavy industry flourished ,which employed a lot of African-American people. But now, the focus is more on information technology and health care, both of which employ only skilled and trained people. This has led to unemployment among African-Americans.
Poverty has many ill effects on society. That’s why steps should be taken to get rid of it!
小題1:What’s the meaning of the underlined word “flourished” in Paragraph 5?(No more than 5words)
________________________________________________________________________.
小題2:Why is overpopulation a cause of poverty today?(No more than 12 words)

When friends and family heard what I was planning, they wondered if I had gone crazy. But here I was in New Mexico, working at a youth farm as a volunteer. I wanted to give back to society. The farm is one of the nonprofit (非盈利的) camps in New Mexico. Founded in 1998, it provides a free camp for the kids whose families are poor. My main responsibility was to look after them.
More than anything, I was excited. I had the opportunity to influence these kids’ lives. I could help them have fun. At the beginning, I couldn’t help feeling nervous. By the end of the first week, I had felt completely at ease. Each child listened to me and enjoyed the games we played. This farm was their heaven, and each child truly felt beatific.
Harrison was probably the most troubled child I saw all summer. He couldn’t deal with anger. As soon as I met him, it was clear that he’d never been shown kindness or patience. His temper would unexpectedly fly out of control. He refused to play games with us and hit other kids at the very start. He was always worried that I would shout at him or hit him. I told him that I would never do that. And I simply educated him to be a kind and patient boy. After Harrison’s going home, his mother wrote to tell me how differently her son reacted to others and how much gentler he had become.
The kid was not the only one that changed. I changed, too. I grew to appreciate my caring family. I became more patient, too. My eyes were also opened to the different situations people live in. Giving myself to show them love was the most meaningful part of my service. As the saying goes, love is, above all, the gift of oneself.
小題1:For what purpose did the author work at the youth farm? (no more than 6 words)
___________________________________________________________________________
小題2:What kind of kids could come to the camp? (no more than 6 words)
