In a world with limited land, water and other natural resources, the harm from the traditional business model is on the rise. Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable (可持续的) ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources.

Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil， which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.

Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emission (排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate (加速) the change from traditional model to a sustainable one.

    The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.

It is 4 o’clock in the early morning. Everything but the computing room on the campus of the university appears as quiet and misty as the mysterious hell. In the computing room, 30 students with sleepy eyes, sit still at their desk, beating the dirty and worn keys. Staring at the colorful screen, they tap continuously for hours. For the other parts in the world, it might be in the middle of the night, nevertheless here time represents nothing. It is an entirely enclosed field. These young computer “hackers” are tracing a sort of stimulus (刺激), a drive so exciting and absorbing that it ignores nearly anything else in their lives and becomes the focus of their being. They are addicted (上瘾的) computer programmers. Some of these students have been glued to the console (电子设备的操纵台) for no less than twenty hours even with no break for meals or rest. Some have been sleeping on sofas and chairs in the computing room, trying to struggle for a few moments’ rest but hating to get too far away from their addicted machines.

         It is not necessary for most of these students to be at the computing room in the middle of the night. What they are working belong to no assignments. They remain there because they desire to be — they can not resist the attraction of the computers.

         Furthermore, they are in groups instead of being alone. There are hackers at computing rooms all over the country. In the unimaginable way, they focus on nothing but computer. They escape from schooling and live beyond friendship; they might have difficulty being employed, choosing to travel from one computing room to another. They may even give up personal health.

         “There is one hacker in my memory. We actually had to lift him away from his chair to feed him and arrange him to rest and sleep. We truly worried about his health,” says a computing science professor at California University.

         Professors of computer science are nowadays paying more attention to this hacker phenomenon and are on the watch for future hackers and more and more severe computer addicts. They believe firmly that hackers are not simply resulted from the close relationship with a machine. It is the result of social relationship with the attractive thinking machines, which are becoming nearly universal.

1.We can learn from the passage that those at the computing room in the middle of the night are      .

A. students working on a program

B. students using computers to amuse themselves

C. hard-working computer science majors

D. students deeply fascinated by the computer

2.Which of the following is NOT true of those young computer “hackers”?

A. Most of them are top students majoring in computer programming.

B. For them, computer programming is the only purpose for their life.

C. They can stay with the computer at the computing room for nearly two days.

D. Their love for the computer is so deep that they want to be near their machines even when they sleep.

3.It can be reasonably inferred from the passage that ______.

A. the hacker phenomenon exists only at university computing rooms

B. it is not very easy for the “hackers” to find friends or jobs

C. university computing rooms are expecting outstanding programmers out of the “hackers”

D. the hacker phenomenon is partly due to the lack of the computing rooms

4.According to professors of computer science, the hacker phenomenon can be described as      .

A. positive                B. disgusting

C. worrying              D. admiring

5.Which of the following may be the most appropriate title for the passage?

A. The Charm of Computer Science       B. A New Type of Electronic Toys

C. Future Computer Programmers         D. Computer Addicts

1.______________              

         You’re probably most familiar with college dictionaries, often called abridged dictionaries．Although abridged means “shortened” , these dictionaries contain more than 150,000 entries and provide detailed definitions that are sufficient for most college students and general users. College dictionaries also contain separate lists of abbreviations, biographical and geographical names, foreign words and phrases, and tables of measures. Webster’s II New Riverside University Dictionary and the American Heritage Dictionary of the English Language are college dictionaries.

2.______________              

         Unabridged dictionaries contain as many as 500,000 entries and provide detailed definitions and extensive word histories (etymologies). These dictionaries, possibly in several volumes and mostly found in libraries, are excellent sources for scholarly inquiries. Unabridged dictionaries include the Oxford English Dictionary and the Random House Dictionary of the English Language.

3.______________              

         A dictionary entry has many elements: multiple definitions, syllabication (音节划分), preferred spelling and pronunciation (some words have more than one acceptable spelling and pronunciation) , and part-of-speech labels. Some entries also include plurals, capitalized forms, synonyms, antonyms, and derivatives. Americanisms and etymologies may be provided along with usage notes, cross-references, and idioms.

4.______________              

         If you prefer using the dictionary on a computer, you can obtain CD-ROM versions of many major dictionaries. In addition, you can access numerous electronic dictionaries, such as WW Webster’s Dictionary, on the Internet. Online dictionaries allow you to enter a search word (you even get help with spelling) to see a definition, and sometimes even an illustration. Online dictionaries also offer additional features, such as word games, language tips, and amusing facts about words. Some online dictionary services allow you to access numerous dictionaries, both general and specialized.

5.______________              

         Specialized dictionaries provide in-depth information about a certain field. For example there are dictionaries for the specialized vocabularies of law, computer technology, and medicine. In addition, there are dictionaries of synonyms, clichés, slang, and even regional expressions, such as the Dictionary of American Regional English (DARE). There are also dictionaries of foreign languages, famous people’s names, literary characters’ names and place names.

I still remember my middle school life in that small town. I am then in a school for students from Tibet. As we all left home at a early age, we met lots of problems in our daily life. We had to do the washing, cleaning and shopping by us. However, we seldom felt lonely or helplessly. We enjoyed our happy life. At weekends, we would play basketball, swam in the pool or go for a picnic. We are lived in a big family. We treated each other brothers and sisters. If any one of us had any difficulty with his studies, the other student would help him out. It has been five years when we graduated, but those memories are as sweet as never before.
