Parties, iPods, concerts, movies, TV shows, video games, traffic. All of these things of the modern world make life entertaining and enjoyable. But our 21st-century lifestyle is also loud and, if we don’t take notice, it can have an effect on our hearing.
Most teenagers don’t think about hearing loss. But if you experience any of the following symptoms（症状）, you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people’s expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears.
iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of its maximum volume（最大音量）, and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal.
Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss.
Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it’s like working in a loud factory all day, being a maintenance（修理）person under a jet airplane or using a jackhammer（手提钻）on a building site.
Similarly, iPod music can cause a short time or permanent（永久的）hearing damage. A loud iPod can cause a ruptured（破裂的）eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to the auditory nerves（听觉神经）that connect to the brain. If this happens, hearing loss becomes permanent.Which of the following shows that you are suffering hearing loss?
| A．You are interested to listen to others’ talking. |
| B．You have to read others’ expressions to understand them. |
| C．You can only understand others over the phone. |
| D．You always think you hear the ringing of the phone. |
Which of the following is TRUE when you listen to music?
| A．Listen at least an hour every time. |
| B．Turn up the volume to the highest level. |
| C．keep the sound lower than 60% of its highest volume. |
| D．Choose classical, rock or heavy metal music. |
What is the correct order of causing permanent hearing loss?
a. The eardrum is broken.
b. The auditory nerves cannot receive sounds.
c. Tiny hairs are damaged.
d. Ear buds are placed directly in the ear canal.
e. High-volume music is played over a long time.

LONDON—Life for Cathy Hagner and her three children is set to permanent(永久的) fast-forward.
Their full school day and her job as a lawyer's assistant are busy enough. But Hagner also has to take the two boys to soccer or hockey or basketball while dropping off her daughter at piano lessons or Girl Scout Club.
Often, the exhausted family doesn't get home until 7 pm. There is just time for a quick supper before homework. In today's world, middle-class American and British parents treat their children as if they are competitors racing for some finishing line.
Parents take their children from activity to activity in order to make their future bright. It seems that raising a genius has become a more important goal than raising a happy and well-balanced child.
"Doctors across the country are reporting a growing number of children suffering from stomachaches and headaches due to exhaustion and stress," says child expert William Doherty of the University of Minnesota.
Teachers are dealing with exhausted kids in the classroom. It's a very serious problem. Many children attend after-school clubs by necessity. But competitive pressures also create an explosion of activities. They include sports, language, music and math classes for children as young as four.
"There is a new parenting trend under way which says that you have to tap all your child's potential at a young age; otherwise you will let him down,” says Terry Alter, a Cambridge-based child and adolescent psychiatrist （青少年精神病专家）
"It isn't entirely new: there have always been pushy parents. But what was previously seen as strange behaviour is now well accepted."From the second paragraph of this passage we can find that ______.
| A．Hagner wastes much time helping her children's lessons |
| B．Hagner doesn't spend much time on her full-time job |
| C．Hagner is interested in spots and music |
| D．Hagner busies herself by following a trend |
British parents, as the writer described in this passage, _____.
| A．treat their children as spots players |
| B．pay no attention to their children's lessons |
| C．bring up their children in a simple way |
| D．give their children little time to develop freely |
The writer's opinion about after-school clubs is that ______.
| A．activities in the country are too competitive |
| B．children should attend four clubs at a time |
| C．some clubs result in competitive pressures |
| D．clubs should have more subjects for school children |
The last paragraph tells us that in Britain ______.
| A．parents used to take their children to every club |
| B．parents used to be wise on how to raise children |
| C．parents have all benefited from children's clubs |
| D．parents have come to know the standard of education |
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. |

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. |
