On Friday, the Food and Drug Administration (FDA) released two proposals to improve food safety. The regulations are a response to a series of recent foodborne illnesses. The FDA hopes these new rules will prevent problems of food in the earliest period of production, before the contaminated（受污染的）food causes consumers to get sick.

Over the past decade, foodborne illnesses have caused many people to get sick. Food like spinach（菠菜）, ground beef and cantaloupes（甜瓜）has been sent back to producers, because it is bound to contain germs and bacteria that cause illnesses.

Among the most common problems are dangerous bacteria that cause stomach pains and food poisoning. Often these illnesses occur when food is undercooked or improperly prepared. While not all illnesses are reported, the FDA estimates that nearly 130,000 Americans a year are hospitalized for food-related problems.

The two new rules proposed by the FDA are called Preventive Controls for Human Food and Standards for Produce Safety. Each rule is described in detail on the FDA’s website. Readers can submit comments, which the FDA will use as feedback to mike future adjustments to the proposals.

The first rule demands manufacturers should have formal plans for preventing contamination and for fixing problems when contamination occurs. This regulation is applied to food produced in the US and overseas.

The second rule k specific to food that is eaten raw. It requires strict standards of growing harvesting, and packing fruit and vegetables. Workers must make sure the materials used in soil are safe and free of contamination.

The FDA believes these new rules will not just improve Americans’ health but also make a positive economic impact. The regulations can lead to major savings in medical costs for people who get sick because of the contamination food.

If manufacturers are able to fix problems at source, they will prevent future issuer However, putting the proposals into action will lake lime and money.

1.Why are the two proposals released by the FDA?

A. To make sure food is safe　　 B. To increase the variety of food

C. To raise people’s health awareness　　 D. To prevent disease from s|>reading

2.Which way will you use to express your opinions about the two rules?

A. E-mail the FDA　　 B. Call the FDA office

C. Visit the FDA website　　 D. Write a letter to the FDA

3.Who are the two new rules proposed by the FDA intended for?

A. Food suppliers　　 B. Food manufacturers

C. Consumer　　 D. Food processors

The Food and Drug Administration is, again, threatening to impose(征税) milk and meat from cloned animals on a public that opposes the technology and its products.

Respected polls report that more than 60% of Americans think animal cloning is immoral, and that most people said they wouldn’t knowingly eat the products even if the FDA approved them. But because the FDA would allow cloned meat and milk to be sold without identifying labels, consumers wouldn’t be able to avoid them. The FDA has consistently tilted toward those who want cloned milk and meat in our food. Agency officials have repeatedly asserted that science shows cloned milk and meat are safe for humans. But the FDA has never published the complete scientific studies it says support that claim.

The argument that cloning is safe for animals is unconvincing. Cloned meat and milk offer no public economic benefits. Having cloned cows produce more milk wouldn’t reduce milk prices. US farmers produce more milk than we drink, and the government is required to buy the surplus. Since 2000, dairy support programs have cost taxpayers more than $ 5 billion.

Most important, this first decision to advance animal biotechnology raises ethical issues beyond the FDA’s expertise（专家意见）. Techniques used to clone animals will advance the ability to clone humans－and create animals with human genes. Neither the agency nor animal scientists are qualified to tell us whether and when it is ethically acceptable for humans to alter the essential nature of animals. We need a national discussion, including ethicists and religious leaders, to consider the wisdom of cloned and transgenic animals. Given the risk of unintended consequences, we should proceed cautiously. The president should halt further FDA action on cloning and set in motion(运作) a process for beginning this broader discussion.

1. The author’s attitude towards cloning is __________.

A. standing in the middle      B. opposed     C. approving      D. supportive

3. In US many people buy cloned foods __________.

A. to support the new technique

B. because FDA approved them

C. because they cannot tell which is cloned food

D. because they cannot read the labels.

3. From the text we know that cloning technique ___________.

A. developed well enough to clone human beings

B. may cause unintended bad results to human beings

C. will bring more unexpected economic benefits

D. is supported by ethicists and religious leaders

4. What’s the best title of this passage?

A．Public Is Against Cloned Food     B．Benefits of Cloned Food

C．Cloned Food Is Illegal             D．Technique in Cloned Food

“The U．S.Food and Drug Administration(FDA)is considering to put stricter limits over tanning salons(晒黑廊)and wants to ban anyone younger than 18 years of age from using a tanning bed，”an advisory panel(专家团)announced last week.

The panel is calling for tighter controls on the industry such as requiring teenagers to get the approval from their parents before using tanning beds or limiting the use of artificial tanning to a certain age.“Given the absence of any demonstrated benefits，I think it is an obligation for us to ban artificial tanning for those under 18，”said panelist Dr.Michael Olding.

Along with a possible ban for teenagers，the panel also recommended that visible warning labels should be placed either on the tanning machines or in the salons in order to caution tanners of the possible dangers.In addition，the committee decided that stricter regulations and classifications were critical to make the machines safer.At this time the machines are categorized as FDA Class 1 devices，the ones that are least likely to cause harm.In case the FDA decided to change their classification from Class 1 to Class 2，as advised by the panel，the FDA could limit the levels of radiation the machines emit.Class 2 devices include X­ray machines and powered wheelchairs.

Getting a tan，whether from a tanning bed or the sun，increases the risk of developing skin cancer.Last year，the World Health Organization's International Agency for Research on Cancer (IARC)declared tanning beds as “carcinogenic(致癌的)to humans”．It was discovered that young individuals in their teens and 20s who use tanning beds on a regular basis have a 75 per cent higher risk of suffering from melanoma(黑素瘤)，the deadliest form of skin cancer.According to the American Cancer Society，melanoma accounted for nearly 69,000 cases of skin cancer in 2009 and will account for most (about 8,650)of the 11,590 mortality cases due to skin cancer each year.

1.According to the passage，what measures will U．S.FDA most probably take?

A. Banning tanning salons.

B. Posing heavier tax over tanning salons.

C. Having tighter controls over tanning salons.

D. Limiting the number of tanning salons in every state.

2.Which of the following suggestions for making tanning salons safer is NOT mentioned?

A. Visible caution.

B. Setting age limit.

C. Professional personnel.

D. Parental approval for teenagers.

3.What does the writer want to express in the last paragraph?

A. Tanning in one's youth may mean death.

B. Tanning in the sun is safer than on the tanning bed.

C. People should get tanned without getting melanoma.

D. Getting tanned is only a good idea for those above thirty years old.

4.What will most probably happen，if the advisory panel's suggestions are adopted and put into practice?

A. Fewer people will suffer from skin cancer.

B. Tanning salons will have more customers.

C. Getting a tan in a tanning salon will cost less.

D. Parents will be more anxious about their tanning children.

Children in the United States eat too much pizza that some researchers now argue the food should join the ranks of sugary drinks and fast food for the harm they do to health．

In a new study, the researchers found that pizza is a large source of calories, saturated fat(饱和脂肪)and salt in children’s diets．Children should not eat more than two slices of pizza for a meal，and should pair that with salad, rather than with another high-calorie food，the researchers concluded．

“Parents should aim to control pizza consumption(消费), particularly as a snack where it was shown to have a very adverse impact on children, and they should put their pizza dollars toward healthier brands．”Said Lisa Powel, director of the Illinois Prevention Research Center．

Pizza has become a matter of focus in recent years for researchers who look at the meals children eat, rather than the nutrients within them．Studies have found pizza is among the greatest sources of calories for children．

“Since pizza remains a common part of children’s diet, we need to make ‘healthy’ pizza．”Powel said．To make pizza healthier, food producers should reduce its saturated fat and salt, and increase its whole grain content,” she said．

Whether or not pizza is harmful enough to be picked out as an unhealthy food, the study attracts attention to a larger issue with the modern American lifestyle, said Alexis Tindall, who was not involved in the flow research. “Many foods are eaten too frequently and in large sizes,” said Tindall．To solve the problem, people don’t have to give up eating pizza, but instead, they can eat smaller and healthier pizza，”she said．

“Make it at home, instead of ordering it out where you don’t have any control over how it’s made.” Tindall said. “When we make it at home, we can choose healthier ingredients，increase the vegetables, reduce fat, and put in less cheese．Pizza doesn’t have to be just pepperoni(意大利辣香肠)and cheese．”

1.According to the research, children shouldn’t eat　　　　 ．

A．more than two slices of pizza in a day

B．two slices of pizza for a meal

C．pizza along with salad

D．more pizza with French fries

2.Powel suggests healthier pizza should be made 　　　　　　 ．

A．with more ingredients　 B．with less salt

C．in smaller sizes　　　　 D．at home

3.The last sentence of the passage implies that pepperoni and cheese　　　　　　 ．

A．are necessary ingredients of pizza

B．are not the only healthy ingredients of pizza

C．should all be replaced with healthier ingredient．

D．should be reduced by adding healthier ingredients．

4.What is the best title for the passage?

A．Pizza—a real junk food!

B．How to prepare better meals for your kids?

C．Discover the harm of eating pizza

D．Bring in healthier pizza for Americans

高二英语单项填空中等难度题查看答案及解析

Eating too much fatty food，exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.

Previous studies have linked high exposure（暴露）to environmental pollution to an increased risk of heart problems, but two analyses now show that poor air quality can cause heart attack or stroke（中风） within as little as a few hours after exposure. In one report of the research, scientists found that people exposed to high levels of pollutants（污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. Another study of stroke patients showed that even air that the U.S. Environmental Protection Agency（EPA）considers to be of　 “moderate”(良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.

The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

1.The text mainly discusses the relationship between _________ .

A. heart problems and air quality

B. heart problems and exercising

C. heart problems and smoking

D. heart problems and fatty food

2.The underlined word “modest” in Paragraph 3 most probably means _________ .

A. relatively high　　　　　　　　　　　 B. extremely low

C. relatively low　　　　　　　　　　　　 D. extremely high

3.We can learn from the text that __________？

A. eating fatty food has immediate effects on your heart.

B. the EPA conducted many studies on air quality.

C. moderate air quality is more harmful than smoking.

D. stricter regulations on pollutants should be made.

4.The author’s purpose of writing the text is most likely to _________ .

A. inform　　　　　 B. persuade　　　　　 C. describe　　　　　 D. entertain
