There are three branches of medicine. One is called "doctor medicine," or "scientific medicine." Scientific doctors try to observe sicknesses, look for logical patterns, and then find out how the human body works. From there they figure out what treatments may work. This kind of medicine is believed to date from the 4th century BC. Although nowadays it is successful, in the ancient world this approach probably did not cure many patients.
A second kind of medicine is called "natural cures," or "folk medicine," in which less educated people try to cure sicknesses with various herbs. These folk healers also use observation and logic, but they are not so aware of it. They try things until they find something that seems to work, and then they keep doing that. Folk medicine flourished（繁荣） long before the development of scientific medicine and was more successful in ancient times than doctor medicine.
The third kind is called "health spas," or "faith healing." Sometimes this may be as simple as touching the holy man and being immediately healed. Other times, a magician may make you a magic charm, or say a spell, to cure you. Some religious groups organize special healing shrines（圣坛） for the sick. In these places people rest, get plenty of sleep, eat healthy food, drink water instead of wine, and exercise in various ways. They also talk to the priests and pray to the gods. If you are feeling depressed or you have been working too hard, going to these places may be just the right thing to make you feel better. Doctor medicine __________.

Have you ever wondered why the roots of the plants always know which way to grow—into the soil but not above it? Some British scientists have recently solved this mystery.
It turns out that roots have special hairs that tie them into the soil and help them grow their way past obstacles, a team at the John Inners Center in Norwich reports in the February 29 issue of Journal Science.
“The key is in the fuzzy(有绒毛的)coat of hairs on the roots of plants,” says professor Liam Dolan. “We have found a growth control system that enables these hairs to find their way and to become longer when their path is clear.”
Root hairs explore the soil in much the same way a person would feel their way in the dark. If they come across an obstacle, they make their way around until they can continue growing in an opening. In the meantime, the plant is held in place as the hairs grip(紧紧抓住)the soil.
The hairs are guided by a clever chemical trick. A protein(蛋白质) at the tip of the root hairs called RHD2 helps them to take calcium(钙) from the soil. Calcium makes the hairs grow, and produce more RHD2, and take more calcium.
But when an obstacle blocks the hair’s path, or the hair reaches the surface of the soil, the cycle is broken and growth starts in another direction.
This system gives plants the flexibility to explore a complex environment and to live in even the most unpromising soils, says Dolan.
In poor soils such as in parts of Australia and Africa, native plants have adapted by producing enormous numbers of root hairs. A better understanding of this adaptation will allow scientists to develop hairy rooted crops that can grow in unfriendly environments.
According to Dolan, “Research in the John Inners Center is taking a breeding approach to increase hair length in wheat but it will be some time before new cultivars(栽培变种) are developed.”The passage is mainly about _______.
| A．why the roots of plants grow into the soil but not above it |
| B．how the roots of plants grow into the soil but not above it |
| C．the process of plants growth |
| D．a growth control system of plants |
How does the circle work?
| A．RHD2 takes calcium from the soil, which makes hairs grow, and produce RHD2 and take more calcium |
| B．Roots take RHD2 and calcium from the soil and produce RHD2 |
| C．Roots make hairs grow, and produce RHD2, and take more calcium |
| D．RHD2 takes protein, which makes hairs grow, and produce RHD2, and take more calcium |
We can infer from the last paragraph that ________.
| A．hairy rooted crops can grow better in unfriendly environments |
| B．a new cultivar of wheat with long hair has been developed by scientists |
| C．a new cultivar of wheat with long hair is still on test |
| D．the roots of plants always know which way to grow |
Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict,” jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled.” Today David wears casual clothes---khaki pants and sports shirt---to the office. He hardly ever wears necktie. “I’m working harder than ever,” David says, “and I need to feel comfortable.”
More and more companies are allowing their office workers to wear casual clothes to work in the United States. The change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday (but only on Friday). This became known as “dress-down Friday” or “casual Friday.” “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing,” said business consultant Maisly Jones.
Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code. “A lot of young people don’t want to dress up for work,” says the owner of a software company, “so it’s hard to hire people if you have a conservative dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss and Company, 85 percent of employers said that they believe that casual dress improves employee morale. Only 4 percent of employers said that casual dress has a negative impact on productive. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”David Smith refers to himself as having been “a clothes addict” because_______.
| A．he often wore khaki pants and a sports shirt |
| B．he couldn’t stand a clean appearance |
| C．he wanted his clothes to look neat all the time |
| D．he didn’t want to spend much money on clothes |
David Smith wears casual clothes now, because________
| A．they make him feel at ease when working |
| B．he cannot afford to buy expensive clothes |
| C．he looks handsome in casual clothes |
| D．he no longer works for any company |
According to this passage, which of the following statements is FALSE?
| A．Many employees don’t like a conservative dress code. |
| B．Comfortable clothes make employees more productive |
| C．A casual clothes code is welcomed by young employees |
| D．All the employers in the U.S are for casual office wear. |
In this passage, the following advantages of casual office wear are mentioned EXCEPT_______.
| A．saving employees’ money |
| B．making employees more attractive |
| C．improving employees’ motivation |
| D．making employees happier |

Australia has passed regulations that will enable more international students to further their education in the country.
The new measures were released by the Australian Department of Tertiary Education, Skills, Jobs and Workplace Relations in September and will take effect in mid-2012.
As a result, the student visa application process for overseas students has been simplified, and the deposit (押金) required to study in Australia has been reduced. Language requirements for overseas students have also been eased.
Also, overseas students receiving a higher education in Australia will be granted a working visa lasting from two to four years after graduation, as long as they meet the basic IELTS requirement.
"This change will definitely make Australia a more attractive destination for Chinese students planning to study overseas," says Wang Lan , a consultant from Education International Cooperation Group (EIC), a Beijing-based company that provides services to students wishing to study overseas.
However, in the past few years, many of Wang's student clients (客户) could not start studies in Australia because they did not meet the language requirements, visa processing took a long time and deposit regulations were tough. The change in policy is good news for the parents of students wishing to study in Australia, Wang says.
A 22-year-old female student surnamed Li, in Beijing, who is planning to do her postgraduate studies in Australia, learned about the policy change several weeks ago.
"According to the previous deposit requirement for my student visa, my family was required to put down 550,000 Yuan ($86,850). Now we only need to prepare 410,000 Yuan. This is a relief for my parents," Li says.
She also says that the two to four years working visa makes her feel much clearer about her study plans.
"I believe several years of working experience abroad will strengthen my competitiveness when I return to China," she says.
Gaining a competitive advantage is the major reason for Chinese students to study abroad, according to the report by EIC.What's the main idea of the passage?
| A．Language requirement for overseas students have been eased in Australia. |
| B．Australia is a most attractive place for students in China. |
| C．Australia widens window of opportunity for international students. |
| D．More students will work in Australia after their graduation. |
Which of the following is NOT the content of the new regulations?
| A．The student visa application process for overseas students has been simplified. |
| B．The deposit required to study in Australia has been reduced. |
| C．Language requirements for overseas students have been more difficult. |
| D．After graduation, some overseas students can get a working visa in Australia. |

The Internationa1 Space Station allows astronauts to live in space for extended amounts of time, enabling them to explore the outside universe and conduct many experiments. However, nothing like that exists for our oceans, and thanks to the high water pressure, ocean researchers are able to explore what lies undersea for very short periods of time.
They are therefore never able to fully explore the deep inside areas of our oceans. However, if French architect Jacques Rougerie has his way, that will change soon.
Jacques has designed a ship that will allow researchers to spend a long period of time observing the sea life and conducting experiments. The huge l67ft. ship, named ‘Sea Orbiter’, consists of two areas—one above the water where the scientists and crew will live, and a lower pressurized deck (甲板), where scientists will be able to spend as much time as they wish. Since it is powered by sea currents and wind, he expects it to drift (漂流) along the oceans slowly, taking about two years to circumvent the globe.
Jacques will make their life as comfortable as possible in the ship. Besides being equipped with the latest sailing tools and communication equipment, the ship will also have a gym, a television and a DVD player! And these guys will not be eating freeze-dried food like astronauts. Instead, Jacques, an accomplished chef, plans on cooking them delicious meals every day.
The biggest problem to this giant ship is the cost, which is expected to be over $500 million—per ship! However, Jacques, who strongly believes that the secrets of our oceans may be the key to solving global warming and a vital supply for food and medicine in the future, is confident he will be able to convince governments all over the world to help out, and expects to start construction on not one, but four or five of these amazing ships soon!Why can’t ocean researchers explore the deep oceans for a long time?
| A．Because they can’t stand the high water pressure. |
| B．Because it’s too cold in deep ocean. |
| C．Because time for experiments is too limited. |
| D．Because it’s dangerous to observe the sea life. |
The underlined word “circumvent ” probably means.
| A．fly away | B．go around | C．travel through | D．move into |
From the fourth paragraph we can learn that.
| A．Jacques intends to design the ship mainly for sightseeing and traveling |
| B．living a comfortable life helps to do the ocean research quickly |
| C．it’s much more expensive to eat freeze-dried food |
| D．researchers on Jacques ’ ship will live more comfortably than astronauts |
In Jacques’ opinion, which of the following is not the purpose of the undersea research?
| A．To find supply for food in the future. |
| B．To find supply for medicine in the future. |
| C．To draw governments’ attention to the construction of the ship. |
| D．To solve the global warming. |
Which of the fol1owing would be the best title for the text?
| A．Sea Orbiter—the ship of the future |
| B．A new way to explore the deep oceans |
| C．A great architect—Jacques Rogerie |
| D．Travel around the globe in Sea Orbiter |
