When a rather dirty, poorly dressed person kneels at your feet and puts out his hands to beg for a few coins, do you hurry on, not knowing what to do, or do you feel sad and hurriedly hand over some money? What should our attitude to beggars be? There can be no question that the world is full of terribly sad stories. It must be terrible to have no idea where our next meal is going to come from. It seems cruel not to give some money to beggars.
Certainly, most of the world’s great religions （宗教） order us to be open-hearted and share what we have with those less fortunate than ourselves. But has the world changed? Maybe what was morally （道德方面） right in the old days, when one knew exactly who in the village had suffered misfortune and needed help, is no longer the best idea. Quite a few people will not give to beggars. Let us look at their arguments.
First, some believe that many city beggars dress up on purpose to look pitiable and actually make a good living from begging. Giving to beggars only encourages this sort of evil （恶行）. Secondly, there is the worry that the money you give will be spent on beer, wine or drugs. Thirdly, there is the opinion that there is no real excuse for begging. One might be poor, but that is no reason for losing one’s sense of pride and self-dependence.
Related to this is the opinion that the problem should be dealt with by the government rather than ordinary people. Some people think beggars should go to the local government department and receive help.
It is hard to come to any final conclusion; there are various cases and we must deal with them differently. A few coins can save a life in some situations, and even if the money is wasted, that does not take away the moral goodness of the giver.

The Pacific island nation of Nauru used to be a beautiful place．Now it is an ecological disaster area．Nauru's heartbreaking story could have one good consequence-other countries might learn from its mistakes．
For thousands of years，Polynesian people lived in the remote island of Nauru，far from western civilization．The first European to arrive was John Fearn in 1798．He was the British captain of the Hunter, a whaling ship．He called the island Pleasant Island．
However, because it was very remote, Nauru had little communication with Europeans at first．The whaling ships and other traders began to visit，bringing guns and alcohol．These elements destroyed the social balance of the twelve family groups on the island．A ten-year civil war started，which reduced the population from 1,400 to 900.
Nauru's real troubles began in 1899 when a British mining company discovered phosphate(磷酸盐)on the island．In fact，it found that the island of Nauru was nearly all phosphate，which was a very important fertilizer for farming．The company began mining the phosphate．
A phosphate mine is not a hole in the ground；it is a strip mine．When a company strip-mines，it removes the to player of soil．Then it takes away the material it wants．Strip mining totally destroys the land．Gradually, the lovely island or Nauru started to look like the moon．
In 1968，Nauru became one of the richest countries in the world．Every year the government received millions and millions of dollars for its phosphate．
Unfortunately, the leaders invested the money unwisely and lost millions of dollars．In addition，they used millions more dollars for personal expenses．Soon people realized that they had a terrible problem—their phosphate was running out．Ninety percent of their island was destroyed and they had nothing．By 2000，Nauru was financially ruined．Experts say that it would take approximately$433，600，000 and more than 20 years to repair the island．This will probably never happen．What might be the author's purpose in writing the text?
| A．To seek help for Nauru's problems． |
| B．To tell a heartbreaking story of a war． |
| C．To show the importance of money |
| D．To give a warning to other countries |
What was Nauru like before the Europeans came?
APeaceful and attractive B．Modern and open
C．Rich and powerful D．Greedy and aggressiveThe ecological disaster in Nauru resulted from
| A．soil pollution | B．phosphate overmining |
| C．farming activity | D．whale hunting |
Which of the following was a cause of Nauru's financial problem?
| A．Its phosphate mining cost much money |
| B．It spent too much repairing the island |
| C．Its leaders misused the money |
| D．It lost millions of dollars in the civil war. |
What can we learn about Nauru from me last paragraph?
| A．The leaders will take the experts' words seriously |
| B．The ecological damage is difficult to repair. |
| C．The island was abandoned by the Nauruans |
| D．The phosphate mines were destroyed |
Like distance runners on a measured course，all of us will move through time in a roughly predictable pattern．
In the first stage of our lives，we develop and grow, reaching toward the top of physical vitality(活力)．
After we grow up，however, the body begins a process of gradually wearing out．
A new awareness of physical fitness may help lengthen our years of health and vitality，yet nothing we do will work to stop the unavoidable force of aging．
Most of the changes of aging take place deep inside the body．The lungs become less able to take in oxygen．Powerful muscles gradually lose their strength．The heart loses power and pumps less blood．Bones grow easier to break．
Finally, we meet a stress，a stress that is greater than our physical resistance．Often，it is only a minor accident or chance infection(a disease caused by virus)，but this time，it brings life to an end．
In 1932，a classic experiment nearly doubled the lifetime of rats，simply by cutting back the calories in their diet The reason for the effect was then unknown．
Today, at the University of California at Berkley, Dr．Paul Seagle has also greatly lengthened the normal lifetime of rats．The result was achieved through a special protein limited diet，which had a great effect on the chemistry of the brain．Seagle showed that within the brain，specific chemicals control many of the signals that influence aging．By changing that chemical balance，the clock of aging can be reset．
For the first time, the mystery of why we age is being seriously challenged．Scientists in many fields are now making striking and far-reaching discoveries．
An average lifetime lasts 75 years，yet in each of us lies a potential for a longer life．If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years．What does the underlined word “it” refer to?
| A．Physical vitality． | B．Stress． | C．Aging． | D．Physical resistance． |
Which of the following is not a change of aging?
| A．People gradually lose their muscle strength． |
| B．Bones tend to break more easily． |
| C．The heart loses power and pumps less blood． |
| D．The lungs become unable to take in oxygen． |
The author believes the following except that．
| A．human's life pattern is predictable |
| B．physical fitness can't stop the force of aging |
| C．human's lifetime will last longer than 75 years |
| D．all of the changes of aging take place deep inside the body |
How did Dr．Paul Seagle lengthen the lifetime of rats in his experiment?
| A．By keeping their physical fitness． | B．By cutting the calories in their diet． |
| C．By resetting their clock of aging． | D．By limiting the protein in their diet． |
What is probably the best title for the article?

Heading off to college this year? Here are some fashion tips from our experts you should keep in mind：
Dress to impress．Stylist and business consultant Daniela Smith says，“Girls should keep in mind that your college professors will often be the bridge that connects you to your future career and your classmates will become your professional network，You don't need to dress like you're going to the office, but you．should display all ability to properly present yourself with appropriate maturity and confidence，and look put together．”
Logo mania(品牌狂热症)．Wearing the loges of brands aimed at younger customers physically identifies you as part of that age group，so consider the targeted age group of the stores you shop at．It's tempting to load up on loges，especially well-known loges that signify high-end brands．But consider this：college is a time of self-discovery, a chance to develop your own personal style．Instead of wearing loges head to toe，“walking advertisement”-style，why not express who you really are?
Wear real pants! The combination of leggings and baggy shirts is all too common on college campuses．Smith points out that leggings，yoga pants，and Sweatpants ale entirely unacceptable in public unless you're exercising．Although leggings worn as pants are a common trend among high school and college girls，they are not an appropriate choice for daywear；As a young woman, your style choice should begin to reflect your maturity level．So，get rid of leggings and wear real pants!
Keep the cute factor to a minimum．Stay away from sweaters and T-shirts with smiling animals, cartoon characters，or Hello Kitty on them．Sure，kittens might be cute，but they're not doing you any favors in the style department．Dressing too cutesy can take years off your look，and not necessarily in a good way!The second paragraph indicates the importance of.

Since the 1970s, scientists have been searching for ways to link the brain with computers．Brain-computer interface（BCI） technology could help people with disabilities send commands to machines．
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated（展示）a small robotic wheelchair directed by a person’s thoughts．
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand．He could even talk as he watched the vehicle and guided it with his thoughts．
“Our brain has billions of nerve cells．These send signals through the spinal cord（脊髓）to the muscles to give us the ability to move．But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says．“Our system allows disabled people to communicate with external world and also to control devices．”
The researchers designed a special cap for the user．This head cover picks up the signals from the scalp（头皮）and sends them to a computer．The computer interprets the signals and commands the motorized wheelchair． The wheelchair also has two cameras that identify objects in its path．They help the computer react to commands from the brain．
Prof．Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands．“The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices．One example is this wheelchair．”
He says his team has set two goals．One is testing with real patients, so as to prove that this is a technology they can benefit from．And the other is to guarantee that they can use the technology over long periods of time．BCI is a technology that can .
| A．help to update computer systems | B．link the human brain with computers |
| C．help the disabled to recover | D．control a person's thoughts |
How did Tavella operate the wheelchair in the laboratory?
| A．By controlling his muscles． | B．By talking to the machine． |
| C．By moving his hand． | D．By using his mind． |
The team will test with real patients to .
| A．make profits from them | B．prove the technology useful to them |
| C．make them live longer | D．learn about their physical condition |
Which of the following would be the best title for the text?
| A．Switzerland, the BCI Research Center |
| B．New Findings About How the Human Brain Works |
| C．BCI Could Mean More Freedom for the Disabled |
| D．Robotic Vehicles Could Help to Cure Brain Injuries |
Given Australia’s size and the fact that early settlements were far apart, Australian society is remarkably homogeneous (同种的). Its citizens are fundamentally prosperous and the way of life in the major cities and towns is much the same however many miles divide them. It takes a sharp ear to identify regional accents. However, there is some difference in lifestyle between city dwellers and the country people. Almost 90 per cent of the population lives in the fast-paced cities along the coast and has little more than a passing familiarity with the desert. The major cities preserve pockets of colonial heritage, but the overall impression is modern, with new buildings reflecting the country’s youth. In contrast, the rural communities tend to be slow-moving and conservative. For many years, Australia was said to have “ridden on the sheep’s back”, a reference to wool being the country’s main money earner. However, the wool industry is no longer dominant. Much of Australia’s relatively sound economy is now achieved from natural coal and wheat, and by being the largest diamond producer in the world. Newer industries such as tourism and wine making are also increasingly important. Australians are generally friendly and relaxed, with a self-deprecating sense of humor. On the whole, Australia is a society without hierarchies (等级制度), an attitude generally held to stem from its prisoner beginnings.
Yet, contrary to widespread belief, very few Australians have true prisoner origins. Within only one generation of the arrival of the First Fleet in 1788, Australia had become a nation of immigrants. Originally coming almost entirely from the British Isles, today one in three Australians comes from elsewhere. Australia’s liberal postwar immigration policies led to an influx of survivors from war-torn Europe, most notably Greeks, Italians, Poles and Germans.
The emphasis has shifted in recent years and today the majority of new immigrants are from Southeast Asia. Today Australia is a ‘blend of nations’ and although some racism exists, it has generally been a successful experiment and the country is justifiably proud to have one of the most harmonious multicultural communities in the world.What does the writer mean by saying “It takes a sharp ear to identify regional accents.” in the first paragraph?
| A．Australians speak Standard English with no local accents whatsoever. |
| B．You have to practice a lot to learn to understand the different accents. |
| C．The Australian regional accents are very difficult to understand indeed. |
| D．There is not much difference between the accents in different areas of Australia. |
Which of the following statements is TRUE according to the passage?
| A．Most Australians have ancestors who were prisoners. |
| B．The Australian economy is dependent on sheep exports. |
| C．The majority of people living in Australia come from Europe. |
| D．The pace of life is different in the city and in the country. |
The underlined pronoun ‘it’ in the final paragraph refers to “_______”.
| A．Community | B．racism | C．blend of Nations | D．Southeast Asia |
We can infer from the passage that _____.
| A．there are no signs of Australia’s colonial past in its modern cities |
| B．Australia’s recent immigration policy encourages immigrants from Southeast Asia |
| C．immigrants from Southeast Asia have brought racial problems |
| D．“riding on sheep’s back” resulted in slow development in rural communities |
