题型:不详难度:来源:
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!

A.escaping from reality | B.getting better exam results |
C.curing their narcolepsy | D.leading an active life |
A.cheating in the exam | B.dropping out of school |

Recent figures show seven in ten people use air fresheners or scented candles to keep our homes smelling sweet. Yet recent records suggest that perfumed products could affect our health, causing problems including allergies (过敏), headaches and asthma (哮喘) .
One leading expert believes nearly a third of people suffer health effects from being exposed to scents. A major problem is so-called “contact” allergy—where perfumes and scented products cause eczema (湿疹) when they come into contact with the skin. About one in 20 is thought to be affected by fragrance allergy.
“Often it may not be immediately obvious that you have developed a fragrance allergy,” says Dr. Baron. “You don’t react immediately. Gradually, as you are exposed more and more, the body increases its reaction, until it becomes noticeable to you.”
People with pre-existing eczema are particularly vulnerable (易受影响). “The eczema worsens in areas in contact with perfumes,” says Dr. Baron. “But even those without allergies can be at risk of fragrance allergy.” You can become suddenly allergic to perfumes and personal care products that you have been using for years. “Even if you know which fragrance causes a problem, it can be difficult to avoid, as most personal care products –soap, shampoo, sun cream and washing powder—contain fragrances,” says Dr. Baron.
And strong scents can also cause headaches. Fragrances activate the nose’s nerve cells, stimulating the nerve system associated with head pain. To minimize risk, sufferers are advised to minimize the contact.
“Fragrance suggest cleanliness – yet people are smelling a potentially dangerous chemical mixture,” says Anne Steinemann, professor of the University of Washington. “We often use them to mask one problem – as with air fresheners – but create a greater one – adding poisonous chemicals to the air.”
小题1:What is the text mainly about?
A.The world trend of using fragrance. |
B.The benefits of using non-fragranced products. |
C.The health problems caused by fragrance |
D.The ways of removing allergy. |
A.our bodies have an immediate reaction to fragrance. |
B.seven in ten have suffered fragrance allergy. |
C.fragrance can affect people who don’t have allergy |
D.people can avoid contacting with fragrance easily |
A.Which products contain fragrance? |
B.What’s the influence of fragrance in the air? |
C.What are the air fresheners made up of? |
D.How are headaches caused by fragrance? |
A.the asthma caused by strong scents. |
B.people’s efforts to protect fresh air. |
C.the methods of curing eczema |
D.the bad effects of air fresheners. |
If you have to miss a meal a day, which meal will cause you fewest health problems if you don’t eat it? If you have to make a decision of this type, most people (especially very busy people) will choose to skip breakfast.
However, many experts in the field of health consider breakfast ( the meal which “break” you “fast” ) to be the most important meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients (营养) we need to begin our working day with vigor(活力) and stay hopeful with good honor. However, many people skip breakfast or substitute a cup of coffee for a well balanced meal. What happens if we ignore the importance of breakfast?
One recent study conducted in the United States tested a large number of people. Participants(参加者) included both males and females who ranged in age from 12 to 83. The results showed that if a person eats an adequate(丰富的) breakfast, he or she will work more efficiently(效率高地) and more productively than if he or she skips breakfast or eats a very poor breakfast. This fact appears to be especially true if a person’s work involves mental(脑力的) activities. The study showed that if school-children eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate on their lessons for a longer period of time than if their breakfast is inadequate(不丰富).
The study also showed that contrary to what people believe, if you skip breakfast, you will not lose weight. This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing. So remember, if you want to lose weight, skipping breakfast will not help you. You will likely lose more weight if you decrease your other meals.

A.a good breakfast breaks you down fast |
B.you’ll lose weight quickly if you skip breakfast |
C.breakfast provides what a person needs to work |

C.To change a cup of coffee into a well balanced meal. |
D.To regard a cup of coffee as a well balanced meal. |
A.school-children will be quick and attentive all day if they eat breakfast |
B.a proper breakfast will make mental workers more efficient |
C.fruit, eggs, bread and milk are the best breakfast for mental workers |
D.school-children who have breakfast are much brighter than those who don’t |
A.Some people skip breakfast because they want to be slimmer. |
B.Most people who skip breakfast actually eat more for lunch. |
C.People put on weight because they eat too much breakfast. |
D.Skipping breakfast won’t help people who want to lose weight. |
A.How to Lose Weight | B.What’s a Healthy Diet |
C.Surprising Results of a Study | D.Breakfast – A Meal That Breaks You Fast |
Your body works 24 hours a day. It’s always building and repairing, feeding and cleansing itself. Its goal is to be ready for your every movement, breath, and thought. The quality of your life depends on how well your body works. And how well your body works depends on how much energy it gets. Energy comes from the food you eat. Food contains nutrients that your body needs for growth and energy.
By eating a balanced diet, your body gets the six important nutrients it needs. Minerals(矿物质) are nutrients that build bones and teeth. Minerals also form red blood cells and other substances. Water aids digestion and waste removal. Carbohydrates(碳水化合物) give your body its main source of energy. Two carbohydrates are sugars from foods such as fruits and vegetables and starches found in rice, potatoes, and bread. Fats help build cell membranes(膜). Proteins repair and grow body tissues(组织). Finally, vitamins help your body use carbohydrates, fats, and proteins.
The United States Department of Agriculture(USDA) has created a nutritional food pyramid(金字塔). It shows the daily number of servings you should eat from five food groups. The food pyramid has four levels. The base of the pyramid is the largest level. It contains the bread, cereal, rice, and pasta group from which you need six to eleven servings. The next level has two food groups: vegetables and fruits. The USDA recommends three to five servings of vegetables and two to four servings of fruit. The third level also has two groups: the milk, yogurt, and cheese group and the meat, poultry, fish, dry beans, eggs, and nuts group. You need two to three servings from each of these groups. The top of the pyramid is the smallest level. It contains fats, oils, and sweets. These foods have few nutrients, so eat them sparingly(有节制地).

B.food can improve the quality of your life. |
C.food should be eaten at night as well as during the day. |
D.food will make it easier for you to exercise. |
A.four | B.five | C.six | D.seven |
A.is made up of foods from five food groups. |
B.includes many foods containing fat. |
C.includes six to eleven servings of fruit. |
D.can be got by taking vitamins. |

Car needs gas to run as your body needs food to work for you. Eating the right kinds of food is very important. A good eating habit can help your body grow strong if you take care of what you eat.
There are four main food groups altogether. The dairy group has food like milk, cheese and sour milk. The other three groups are the meat and fish group, the fruit and vegetable group, and the bread and rice group. Each meal should have at least one food from all four main groups. With all of these foods together, you will be given enough energy during the day.
It is easy to get into bad eating habits. You may eat your breakfast in a hurry to get to school on time or you may not have time for a good lunch. It may be easier to eat fish and chips for your supper all the time. But you will find yourself tired and you will not be able to think quickly.
Watching what you eat will help keep your body healthy and strong. It is also good to take some exercise. It will help you eat more if you take a walk or play games in the open air. Having good eating habits with some exercise is the key to your health.
小题1:According to the passage, which of the following diets do you think is the best one?
A.Eggs, tomatoes and chicken. |
B.Milk, bread, cabbages and beef. |

C.Having at least food from one of the four groups each meal. |
D.Having different food from all four food groups. |
A.every person needs food to grow well. |
B.taking exercise can keep your body strong. |
C.the right kind of food with exercise will keep you healthy. |
D.enough energy helps people think more quickly. |
A.the food made out of cows such as milk and butter |
B.the shop that sells milk and butter |

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.
小题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. |
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. |
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-e | B.e-c-a-b-d | C.b-c-a-d-e | D.d-e-a-c-b |
A.music that teenagers like | B.hearing problems caused by the loud world |
C.ways that teenagers enjoy music | D.dangerous modern lifestyles of teenagers. |
