“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine, newspaper, radio and television ads, promising good shapes and new look to those who buy the medicine or the device. The promoters of products say they can shape the legs, slim the face, smooth wrinkles, or in some other way add to beauty or desirability.
Often such products are nothing more than money-making things for their promoters. The results they produce are questionable, and some are dangerous to health.
To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA (Food Drug Administration) can require proof under the Food, Drug and Cosmetic Act that it is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action, including seizure (查封) of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings (法律訴訟), and new devices appear continually, Before buying, it is up to the consumer to judge the safety or effectiveness of such items.
小題1:It can be inferred that ads mentioned in the text are_____.
A.objectiveB.costlyC.unbelievableD.illegal
小題2:The Relaxacisor is mentioned as______.
A.a(chǎn) product which was designed to produce electricity
B.a(chǎn) product whose distributor was involved in a legal case
C.a(chǎn) successful advertisement of a beauty product
D.a(chǎn)n example of a quality beauty product
小題3:The author intends to______.
A.make consumers aware of the promoters’ false promise
B.show the weakness of the law on product safety
C.give advice on how to keep young and beautiful
D.introduce the organization of FDA
小題4:Which of the following is true according to the text?
A. The court is in charge of removing dangerous products.
B. New products are more likely to be questionable.
C. The production of a device must be approved by FDA.
D. The promoters usually just care about profits.

小題1:C
小題2:B
小題3:A
小題4:D

小題1:推理題。根據(jù)第4段第1行Often such products are nothing more than money-making things for their promoters.可知這樣的產(chǎn)品是不值得信任的。故C正確。
小題2:推理題。根據(jù)文章倒數(shù)第2段可知舉這個例子就是為了說明這個產(chǎn)品是經(jīng)銷商涉及法律案件的內(nèi)容。
小題3:推理題。根據(jù)文章內(nèi)容可知文章正是為了讓消費者意識到廠家的虛假諾言,而不要上當(dāng)受騙。
小題4:推理題。根據(jù)文章第四段第一行such products are nothing more than money-making things for their promoters可知廠家只關(guān)心利潤。

 A new survey finds that more than eighty percent of Internet users in the United States search for health information online. The survey found that searching online is one of the leading ways that people look for a second opinion though doctors are still the main source of health information.
Forty-four percent of people are actually looking for doctors or other providers when they search for health information online. Another finding of the survey: Two-thirds of Internet users look online for information about a specific disease or medical condition.
The Internet has also become an important source of emotional support for people with health problems. Susannah Fox says one in five Internet users has gone online to find other people who have the same condition. It was more popular among people with more serious health issues—one in four people living with chronic diseases (慢性病). And it was basically off the charts with people living with rare disease. They are so eager to find other people online who share their health concerns.
A disease is considered rare if it affects fewer than two hundred thousand people worldwide. The rise of social networking has made it easier for people with rare diseases to connect with each other and feel less alone. Social networking is also changing the way some doctors and patients communicate with each other. Dr. Jeff Livingston operates a medical center for women in Irving, Texas. His office uses password-protected software to share information with patients.
“We provide the patient full access to their medical care. Anything I can see, the patient can see. All of their notes, all of their doctor visits are right there. All of their lab work is right there.” Dr. Livingston says the software has increased efficiency, reduced costs and improved relations with patients.
小題1:From the first paragraph, we can know _________.
A.most online health information is reliable
B.more people now turn to the Internet for medical advice
C.people shouldn’t rely on the Internet for medical advice
D.doctors are no longer the patients’ first choice
小題2: The underlined words “off the charts” in Paragraph 3 mean _________.
A.very popularB.not accessibleC.far away fromD.not attractive
小題3: By using social networking, patients with rare diseases can _________.
A.find effective curesB.get emotional comfort
C.a(chǎn)sk for financial supportD.consult doctors anytime
小題4: Which of the following is NOT true of Dr. Livingston’s software?
A.It cuts down medical expenses.
B.It decreases the time spent on medical care.
C.It takes doctors closer to their patients.
D.It gives patients a medical test online.

Eating a diet high in processed(加工) food increases the risk of depression(抑郁), research suggests. What's more, people who ate plenty of vegetables, fruit and fish actually had a lower risk of depression, the University College London team found.
Data on diet among 3,500 middle-aged civil servants were compared with their emotional state five years later, a British journal reported. They split the participants into two types of diet--those who ate a diet largely based on whole food,which includes lots of fruit, vegetables and fish,and those who ate a mainly processed food diet, such as sweetened desserts, fried food, processed meat,refined(精制的) grains and high fat dairy products After accounting for factors such as gender, age, education, physical activity, smoking habits and chronic(慢性的) diseases, they found a significant difference in the future depression risk with the different diets.
Those who ate the most wholefood(全天然食物) had a 26% lower risk of future depression than those who ate the least wholefood. By contrast, people with a diet high in processed food had a 58% higher risk of depression than those who ate a diet low in processed foods.
Study author Dr. Archana Singh Manoux pointed out there was a chance that the finding could be explained by lifestyle factor they had not accounted for.(解釋原因) He also pointed in a paper that a Mediterranean(地中海) diet was associated(有關(guān)) with a lower risk of depression, but the problem with that is if you live in Britain, the likelihood (可能)of you eating a Mediterranean diet is not very high.
Dr.Andrew McCulloeh, chief executive of the Mental Health Foundation, said, this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health.
He added people's diets were becoming increasingly unhealthy. The UK population is consuming (消費)less nutritious, fresh produce and more saturated(飽和) fats and sugars.
小題1:The text is mainly about______.
A.the increasingly unhealthy diet of the UK population
B.the link between processed food and depression
C.the relationship between physical and mental health
D.the emotional state of the British People
小題2:What can we learn from what Dr. Archana Singh Manoux said?
A.It is difficult for most British people to have a Mediterranean diet.
B.The Mediterranean diet is the most healthy in the world.
C.Many studies have been done on the Mediterranean diet before.
D.The Mediterranean diet is not good for depression.
小題3:Dr. Andrew McCulloch agrees that______.
A.our diets are closely related to our mental health
B.the present study needs more facts and other information
C.the UK population will become ill in the near future
D.more saturated fats and sugars should be taken in
小題4:Why might the author have written this text?
A.To tell people what a healthy diet actually is.
B.To prove people’s diets are increasingly unhealthy.
C.To encourage people to cut down on processed food.
D.To introduce some experts on the research team.

It is easy for many people to catch a cold in the springtime or fall. It makes us wonder if scientists can send a man to the moon, why can’t they find a cure for the common cold? The answer is easy. There are actually hundreds of kinds of cold viruses out there. You never know which one you will get, so there isn’t a cure for each one.
When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and cause a block in it. You feel terrible because you can’t breathe well, but your body is actually eating the virus. Your temperature goes up and you get a fever, but the heat of your body is killing the virus. You also have a runny nose to stop the virus from getting into your cells. You may feel very uncomfortable, but actually your wonderful body is doing everything it can to kill the cold.
Different people do different things to deal with colds. In the United States and some other countries, for example, people might eat chicken soup to make themselves feel better. Some people take hot baths and drink warm liquids. Other people take medicine to stop various symptoms (癥狀) of colds.
There is one interesting thing to note —some scientists say taking medicines when you have a cold is actually bad for you. The virus stays in you longer because your body doesn’t have a way to fight it and kill it. Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold. It goes like this:
It takes about one week to get over a cold if you don’t take medicine, but it takes only seven days to get over a cold if you take medicine.

Good health is the most valuable thing a person can have, but one cannot take good health for granted(認(rèn)為……理所當(dāng)然). It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food ,get enough sleep, and exercise regularly.
Proper nutrition (營養(yǎng)) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don't overeat. It is not helpful to be overweight.

Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (壽命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.

In 2030, 42 percent of American adults will be obese, and about one-quarter of that group will be severely obese, a condition that shortens life and wastes large medical expenses, a new study predicts.
Obesity related ailments — diabetes, heart disease, kidney failure — consume at least 9 percent of health-care spending the United States. Some researchers believe the cost may be twice that estimate. Total health spending is about $2.6 trillion a year.
In 2030, 42 percent of people are projected to be obese, and 11 percent severely obese. Obesity is a body mass index , which suggests 85 kg for someone 1.67 meters tall. Severe obesity is 112 kg for someone that height.
Obesity is rising in higher-income men. Severe obesity is increasing in both sexes. It was 6.2 percent in women in 1999 and 8.1 percent in 2010. For men, it was 3.1 percent in 1999 and 4.4 percent in 2010.
It is believed that the obesity rate is closely related to the following factors: the price of gasoline, which discourages walking when it is low; access to the Internet (and other technologies), which encourages long periods of sitting still; and restaurants per 10,000 people, which increases eating out and weight gain when the number goes up.
Urgent measures must be taken to inspire people to exercise more and educate people about better eating habits before too many people will be suffering from being . obese.
小題1:The word “ailments” in the second paragraph is equal to _______.

Your body, which has close relations with the food you eat, is the most important thing you own, so it needs proper treatment and proper nourishment(營養(yǎng)). The old saying “An apple a day keeps the doctor away. ” is not as silly as some people think. The body needs fruit and vegetables because they contain vitamin C. Many people take extra vitamins in pill form(丸劑), believing that these will make them healthy. But a good diet is made up of nourishing food and this gives all the vitamins you need.
