Ever tried taking smart drugs to perform better in exams? They certainly work. Before last summer's exam, a few of my mates, merely out of curiosity, took a considerable amount of Modafinil, a drug normally used for narcolepsy(嗜眠發(fā)作癥). Guess what? While I was feeling sleepy, bored by revision, my mates were more focused.
Modafinil is a smart drug that gives a user a feeling of staying awake for hours. It also sharpens the mind, improves memory and helps problem-solving.
But it does more than just keeping you awake. It disturbs your mental system, making you desperate to do what you are doing. You just don't want to do anything else but revise all the time non-stop.
A recent study discovers that healthy people use smart drugs, like Modafinil, to get down to and complete tasks they have been putting off, because these tasks seem more enjoyable when taking these drugs. This might sound like what a stressed student desires. However, the pills have a range of side-effects.
"At present no evidence shows that these drugs are safe in healthy people," as a medical expert puts it, "Ordering online, though easy, is a dangerous way to obtain drugs. You never know what you're actually purchasing. "
In my experience, Modafinil changes people's behaviour too. Over those weeks my friends became different people—in turn aggressive, cold. Even eating became "a waste of time" and so did conversation.
A BBC survey found that of those who had tried smart drugs before, 92% would do so again. My friends say they'd happily do so without considering the practice a form of cheating.
I admit I was curious—but not enough to try it. Seeing the strange behaviour of other users, I feel a little bit upset and scary. Modafinil may promise to change your grades, but it might also change the way you act. Don't say you haven't been warned!

The Green Microgym in Portland,Oregon has all the usual stuff you'd expect-sweaty people,loud music,smooth exercise equipment-but it has some extras as well. Everywhere you look,there are power wires. And these aren't the typical kind that let you surf the Web while you ride a spin cycle-although. you can do that too.The gym uses special exercise equipment that captures(捕獲)the energy you create while riding, converts(轉(zhuǎn)換)it into electricity and channels it into the power outlets(插座).
The idea of using exercise equipment to produce electricity is not new. A gym in Hong Kong has been doing this since 2007. But clean (and healthy)energy is just now starting to catch on in U. S. gyms·"We have seen a significant increase in interest in the past six months,which is a good sign that fitness centers are ready to spend money on green technologies,” says Mike Curnyn,co-founder of the Green Revolution,a Connecticut-based firm that wires bikes into a central battery that can store energy.
The Green Microgym,first opened in 2008,has more than 200 members and is doing so well that owner Adam Boesel opened another one five miles from the original.Although membership costs about the same as ordinary gyms,customers can earn gift certificates from local businesses for watts produced while exercising.An average workout creates 37. 5 watt hours,which is enough to power a phone for a week.
Boesel uses spin bikes made by Resource Fitness,a Seattle company he co-owns,that captures energy produced from the flywheel. Wires send the converted AC current(交流電流)into any standard wall outlet-for this reason,the product line's name is Plug Out-and the energy created is used before the building draws power from the grid(電網(wǎng)).Unlike the Green Revolution equipment,Plug Out machines cannot store extra energy. A third company,the Florida-based ReRev,is adding converters to a specific brand of spin bikes. But since the converters add$1,000 to the price of the equipment,the ReRev and Green Revolution machines are at a disadvantage.
Resource Fitness,by contrast,sells its equipment for the same$1,200 price as non- electricity-producing machines,removing the question of how long it will be until the energy savings pay for the cost of the unit.The company can afford to do this because its designs don’t call for the extra wiring needed for battery packs and large converters.It is also trying to price competitively with standard equipment so more gyms-and gym goers-will make the switch.
小題1:Members of the Green Microgym earn gift certificates for_______.
A.using the man-powered exercise equipment
B.saving electricity for local businesses
C.producing green electricity to power their phones
D.paying higher membership fees
小題2:The spin bikes made by Resource Fitness are different from those by Green Revolution in that_______.
A.they are easier to ride
B.they are more expensive
C.they don't have wires connected
D.they can not store extra electricity
小題3:What might prevent the green exercise equipment from getting more popular?
A.People's unwillingness to go green.
B.The high cost of making it.
C.Safety problems concerning electricity.
D.Lack of certificates.
小題4:The underlined words“make the switch”in the last paragraph most probably mean_____.
A.change to a different gym
B.use green exercise equipment
C.switch on the spin bikes
D.a(chǎn)dd a battery to the machine

Hearing plays an important part in our everyday life, but few of us take the steps we need to protect our hearing.
It is easy to see how your hearing is under assault in today’s world. There are so many things to hear, and so many new instruments, like iPods and headphones, which can harm your hearing if used improperly. Keeping the volume(音量)to a reasonable level on an iPod or other portable listening instruments is one of the most important ways to protect your hearing. Another great way to keep your hearing protected is to avoid loud noises whenever possible. There are many loud noises from power tools to machinery, and it is important to avoid these noises as often as possible. When it is not possible to avoid them, keep your hearing protected by using earplugs(耳機(jī)).
If you think your hearing may have already been damaged by modern technology, it is important to have your hearing tested by a physician. Only such a professional will be able to measure your level of hearing loss and help you find the best solution to your hearing problem.
For those with hearing issues, the choices have never been greater. There are many excellent hearing aids on the market. Having a hearing aid can be a perfect choice for the young and the old alike, and many people who swore they would never wear a hearing aid find that they love the convenience and quality these instruments represent.
Never let an unimportant thing like vanity(虛榮) get in the way of treating a hearing problem. These days there are hearing aids that are nearly invisible to the naked eye, including a number of models that fit completely inside the ear. If you believe you may be experiencing a problem with your hearing, it is important to have it checked out, and to take the right measures to protect your ears. In many cases, this treatment will be as simple as wearing earplugs. Taking care of your ears is of great importance. After all, you only get one set of ears.                      
小題1:The second paragraph mainly talks about_____.
A.the causes of hearing loss
B.the importance of hearing
C.how to cure hearing problems
D.how to protect your hearing
小題2:The underlined phrase “under assault” in Paragraph 2 most probably means_____.

D.under treatment
小題3:All the following factors may cause hearing problems EXCEPT_____.
A.using iPods improperly
B.listening to MP3 at full volume

D
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(癥狀), 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(手提鉆)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(聽覺神經(jīng))that connect to the brain. If this happens, hearing loss becomes permanent.
小題1: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.
小題2: 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.
小題3: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.
A.d-a-c-b-eB.e-c-a-b-dC.b-c-a-d-eD.d-e-a-c-b

A.music that teenagers likeB.hearing problems caused by the loud world

Lots of kids go through times when they’d like to change their hair. Often, it’s girls who are most concerned(關(guān)心的), but boys may be interested in how their hair looks, too. Sometimes hair will change as you get older----all by itself----when you go through puberty(青春期).
Maybe it used to be lighter and now it’s darker. Or maybe it’s oilier than it used to be, and now you need to wash it more. It’s also normal, as you’re getting older, to notice your appearance more often. You might suddenly decide you want a hairstyle like other kids at school have. But some styles and looks require chemical treatments and long hours in the chair at the hair salon. Some people dye(染)their hair a different color, get a bunch of braids(辮子),or make their hair straight when it’s curly(卷曲). Are these treatments OK for kids? That’s something you should discuss with your parents. At any age, any chemical or heat applied to(應(yīng)用于) the hair can damage the hair or cause it to break off.
Any styling that pulls hard on the hair can also hurt the scalp(頭皮) or cause hair loss. Styling tools, such as curling irons and straightening irons, get very hot and can cause burns. And chemicals used to color, curl, or straighten hair can be very harmful if they get into your eyes or onto your skin.
小題1:The word “kid”in this passage refers to ____________.
A.girlsB.boysC.studentsD.not only girls but also boys

A.If you want to change the color of your hair, you have to use chemical.
B.Hair can be straightened with an instrument.
C.You’d better change your hair with the help of your parents.
D.Hair change by chemicals or instruments can harm the hair or the scalp。

Elderly adults who regularly drink green tea may stay more agile (敏捷的) and independent than their peers over time, according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals (抗氧化物) that may help stop the cell damage that can lead to disease. Researchers have been studying green tea’s effect on everything from cholesterol (膽固醇) to the risk of certain cancers, with mixed results so far.
They found those who drank the most green tea were the least likely to develop “functional disability”, or problems with daily activities or basic needs, such as dressing or bathing.
Specifically, almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled, compared with just over 7 percent of people who drank at least five cups a day.
The study did not prove that green tea alone kept people agile as they grew older. Green-tea lovers generally had healthier diets, including more fish, vegetables and fruit, as well as more education, lower smoking rates, fewer heart attacks and strokes, and greater mental sharpness. They also tended to be more socially active and have more friends and family to rely on. But even with those factors accounted for, green tea itself was tied to a lower disability risk, the researchers said.
People who drank at least five cups a day were one-third less likely to develop disabilities than those who had less than a cup per day. Those people who averaged three or four cups a day had a 25 percent lower risk.
Although it’s not clear how green tea might offer a buffer (緩沖) against disability, Tomata’s team did note that one recent study found green tea extracts (提取物) seem to increase leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts, they do contain caffeine and small amounts of vitamin K, which means it could affect drugs that prevent blood clotting (凝固).
小題1:What can be learned from the passage?
A.Antioxidant chemicals can lead to disease.
B.Those who often drank green tea can’t develop “functional disability”.
C.“Functional disability” is related to problems with daily activities or basic needs.
D.People who drank at least five cups a day are not likely to become functionally disabled.
小題2:What does the fifth paragraph mainly tell us?
A.How the study was proved.B.Why green tea-lovers can keep agile.
C.What healthier diets include.D.How to lower disability risk.
小題3:What have the Researchers discovered?
A.Those who drank green tea can't develop “functional disability”.
B.Green tea alone kept people agile as they grew older.
C.How green tea might offer a buffer against disability.
D.Green tea extracts (提取物) seem to increase leg muscle strength in older women.

A little stress is good, since it helps you keep motivated to meet your goals. However, too much stress is bad for your health. Stress needs to be managed in order to prevent anxiety (焦慮). Here are some tips on how to manage stress.
Write it out
Write down everything that seems stressful, and ways to deal with each problem. You’ll find a things-to-do list much easier to manage than having all messed up in your head. Write down the tasks along with the specific times when you can do them.
One task at a time
Give each task all your attention while you’re doing it, and forget the rest. This will keep you from feeling anxious about things you have left to do. Thinking about other tasks only adds unnecessary stress, and can even stop you from doing the task you’re busy with at present. You don’t need to do everything all at once, or on your own. The feeling of being pressed to finish something on time will somehow disappear if someone is there to help you.
Give yourself a reward
Rewarding yourself for what you’ve already done, no matter how small, is a great way to motivate yourself to keep going. It will reduce stress, and make you happier to go on with the next task.
Give yourself a break
Breaks of ten to fifteen minutes are important. Visit a cafe or take a quick walk —anything to take your mind off the work for a while. If you need to stay at work, sit with your eyes closed and imagine a peaceful place or some other relaxing scenes. This will remove the stress from your muscles and mind.
小題1:The best title for the passage would probably be _____.
A.Stress Is Good or Not
B.How to Form Good Working Habits
C.Tips on How to Manage Stress
D.Ways to Keep Healthy
小題2:According to the passage, which of the following is NOT true?
A.It’s better to plan a specific time to do the task.
B.It helps you stay motivated to think about the undone tasks.
C.It’s unnecessary for you to do all the tasks by yourself.
D.It helps if you put your attention to one task at a time.
小題3:Which of the following would the author agree?
A.The more stress you have, the more motivated you will be.
B.Writing down everything seems impossible.
C.Only reward yourself for your biggest achievements in your work.
D.It is necessary to have a break during your work.
小題4:What can we learn from the passage?
A.Stress is always bad for people.
B.Imagining a relaxing scene may help.
C.The best way to relax is by rewarding yourself.
D.Finishing tasks on time reduces stress.
