FDA proposed the most sweeping food safety rules in decades, requiring farmers and food companies to be more cautious in the wake of deadly outbreaks in peanuts, cantaloupe (瓜），and leafy greens.
The long-overdue regulations are aimed at reducing the estimated 3,000 deaths a year from foodbome illness. Just since last summer, outbreaks of listeria (李氏桿菌）in cheese and salmonella(沙門氏菌）in peanut butter, cantaloupe and mangoes have been linked to more than 400 illnesses and as many as seven deaths, according to the Centers for Disease Control. The actual number of those sickened is likely much higher.
The FDA’s proposed rules would require farmers to take new precautions against contamination (污染）,to include making sure workers5 hands are washed, irrigation (灌溉） water is clean, and that animals stay out of fields. Food manufacturers will have to submit food safety plans to the government to show they are keeping their operations clean.
Many responsible food companies and farmers are already following the steps that the FDA would now require them to take. But officials say the requirements could have saved lives and prevented illnesses in some of the large-scale outbreaks that have hit the country in recent years.
In a 2011 outbreak of listeria in cantaloupe that claimed 33 lives ，for example, FDA inspectors found pools of dirty water on the floor and old, dirty processing equipment at the Colorado farm where the cantaloupes were grown. In a peanut butter outbreak this year linked to 42 salmonella illnesses ，inspectors found samples of salmonella throughout a New Mexico peanut processing plant and multiple obvious safety problems ，such as birds flying over uncovered trucks of peanuts and employees not washing their hands.
Under the new rules, companies would have to lay out plans for preventing those sorts of problems and how they would correct them.
“The rules go very directly to preventing the types of outbreaks we have seen/，said Michael Taylor, FDA’s deputy commissioner for foods.
小題1:The main task of FDA is probably______
A．to protect and promote the public health
B．to help those sickened recover
C．to research on food safety measures
D．to deal with water pollution
小題2:According to the passage, the new rules focus on_____.

British researchers have found that children’s IQ predicts their probability of becoming vegetarians (素食者) as young adults.
Recent studies suggest that vegetarianism may be associated with lower cholesterol (膽固醇), reduced risk of overweight and heart disease.
“We know from other studies that brighter children tend to behave in a healthier fashion as adults—they’re less likely to smoke, less likely to be overweight，less likely to have high blood pressure and more likely to take exercise.” lead author Catharine Gale said, “This study provides further evidence that people  with a high IQ tend to have a healthier lifestyle.”
In the study, Gale’s team collected data on nearly 8,200 men and women aged 30, whose IQ had been tested when they were 10 years of age.
“Children who scored higher on IQ tests at age 10 were more likely than those who got lower scores to report that they were vegetarian at the age of 30.”Gale said. 
The researchers found that 4.5 percent of participants were vegetarians. Of these, 2.5 percent were vegan, and 33.6 percent said they were vegetarian but also ate fish or chicken.
There was no difference in IQ score between strict vegetarians and those who said they were vegetarian but also ate fish or chicken，the researchers added.
One expert said the findings weren’t the whole answer，however.
“We don’t know the beliefs or attitudes of the parents of the children，nor do we know if there was a particular event that led these children to becoming vegetarian in their teens or adulthood.” said Lona Sandon, and assistant professor at the University of Texas Southwestern Medical Center at Dallas.
小題1:From the article，we know that ________.
A．brighter children are likely to become vegetarians when they are ten.
B．people with a higher IQ will not be overweight
C．brighter children are likely to have a healthier lifestyle
D．overweight may cause high blood pressure
小題2:What does the underlined word “vegan” in the sixth paragraph mean?
A．Someone who only eats vegetables.
B．Someone who chooses not to eat meat or fish.
C．Someone who likes eating meat and fish.
D．Someone who likes eating vegetables.
小題3:This study left some unanswered questions EXCEPT “________”．
A．Did the vegetarian children grow up in a family with a vegetarian parent?
B．Did the children eat a primarily vegetarian diet at the age of 10?
C．Were meatless meals regularly served in the participants’ families?
D．Did the vegetarian children really have a high IQ?
小題4:The main idea of the passage is that ________.
A．the low IQ children will be unhealthier when they grow up
B．being vegetarians can reduce the risk of overweight and heart disease
C．IQ is important to vegetarians
D．high IQ children are more likely to become vegetarian when they grow up

When I was small and my grandmother died, I couldn’t understand why I had no tears. But that night when my dad tried to cheer (使…快活) me up, my laugh turned into crying.
So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so does crying.
Whatever it takes for us to reduce pressure is important to our emotional (情感的) health, and crying seems to work well. One study found that 85 percent of women and 73 percent of men report feeling better after crying.
Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and more friendly and they are more ready to offer support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we're very sad until we cry. We learn about our emotions through crying, and then we can deal with them.
Just as crying can be healthy, not crying — holding back tears of anger, pain or suffering — can be bad for physical health. Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural — and healthy — emotional response.
小題1:Why didn't the author cry when her grandmother died?
A．Because her father did not want her to feel too sad.
B．Because she did not love her grandmother.
C．Because she was too shy to cry at that time.
D．The author doesn’t give the explanation.
小題2: It can be inferred (推斷) from the text that ______.
A．there are two ways to keep healthy
B．laughing does more good to health than crying
C．crying and laughing play the same roles
D．emotional health has a close relationship to physical health
小題3: According to the author, which of the following statements is true?
A．Crying is the best way to get help from others.
B．Holding back tears may cause some health problems.
C．We will know our deep feelings if we cry.
D．We must cry if we want to reduce pressure.
小題4:What might be the best title for the text?
A．Power of TearsB．How to Keep Healthy
C．Why We CryD．A New Scientific Discovery
小題5: What might the underlined word “fight” in the last paragraph mean?
A．come backB．pay backC．hold backD．give back

Different exercise types have different purposes and different benefits. One type of exercise may not accomplish all goals of being physically fit: a healthy heart, strong muscles and bones, and safety from injury. As a result, it is important to do enough types of exercise to have all the physical benefits. Here is a quick check sheet.
Aerobic Exercise: To have a strong and healthy heart, you need to do aerobic exercise. This means that you need to exercise yourself enough so that your heart rate, while exercising, is 65 percent to 85 percent of your maximum heart rate. If you don’t get your heart rate up within this level—you just aren’t working hard enough. Whatever you do, your heart rate needs to be 65 percent to 85 percent of your MHR for 20 to 30 minutes, at least 3 times a week. Typical types include:
* Running
* Walking (at least 4 to 4.5 mph)
* Swimming
* Biking
* Elliptical Training (橢圓運(yùn)動(dòng))
* Yoga
Strength Training: To keep your muscles and bones strong, you need to do strength training. This comes in a variety of forms. Whatever you do, however, you need to train your muscles enough so that they are really tired by the end of each session. To see real benefits, make sure you are strength training 2 to 3 times a week for about 30 to 40 minutes. Typical types of strength training include:
* Weight Training
* Yoga
* Resistance Training
* Plyometrics（肌肉增強(qiáng)訓(xùn)練）
Flexibility Training: To keep your body flexible, reducing risk of injuries and pain in your joints and muscles, you need to do flexibility training. You should always aim to stretch every muscle after any exercise routine. Typical types of flexibility training include:
* Stretching
* Yoga
* Pilates（普拉提課程）
So next time you think that yoga 5 times a week will be enough, think about what it is really doing. Is it getting your heart rate up? Are you making up your strength? Are you keeping your muscles flexible?
小題1:If your purpose is to _______, you can choose swimming as your exercise form.
A．build a strong and healthy heart
B．keep muscles and bones strong
C．keep body flexible
D．reduce risk of injuries and pain in joints and muscles
小題2:After reading this passage, we know that ________.
A．Yoga is really better for people than running
B．The more exercise you do, the better
C．Flexibility training helps you build up your muscles
D．The three kinds of training have links with one another
小題3:Which of the following is closest in meaning to “session” in Paragraph 3?
A．meetingB．gatheringC．periodD．term
小題4:The paragraph following this article may discuss_______.
A．how to find a good workout dealing with two or three of these goals
B．how to choose an exercise type
C．how to build up our strength
D．how to be more flexible

Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors — or doesn’t it?
　　While such vigilant(警覺的)tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it’s important to weigh the health benefits of screening against the risks and costs of routine testing.
　　In many cases, screening can lead to additional biopsies and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups. 
　　It’s hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy(預(yù)期壽命).
　　A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening- especially considering the explosion of the elderly that will soon swell our population.
　　It’s not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves. We need to think about the rational use of health care and stop talking about the rationing of health care.”
　　That means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.
小題1:Why do doctors recommend routine cancer screening for elderly people?
A．It is believed to contribute to long life.
B．It is part of their health care package.
C．The elderly are more sensitive about their health.
D．The elderly are in greater danger of tumor growth.
小題2:How do some researchers now look at routine cancer screening for the elderly?
A．It adds too much to their medical bills.
B．It helps increase their life expectancy.
C．They are doubtful about necessity.
D．They think it does more than good.
小題3:What is the conventional view about women screening for breast cancer?
A．It applies to women over 50.
B．It is a must for adult women.
C．It is optional for young women.
D．It doesn’t apply to women over 74.
小題4:Why do many doctors prescribe routine screening for cancer?
A．They want to protect themselves against medical disputes.
B．They want to take advantage of the medical care system.
C．They want data for medical research.
D．They want their patients to suffer less.
小題5:What does the author say is the general view about health care?
A．The more, the better.
B．Prevention is better than cure.
C．Better early than late.
D．Better care, longer life.
