The US Government has decided that meat from cloned animals is safe to eat and does not require special labeling(标记).
The Food and Drug Administration(FDA)planned to speak to industry groups before an announcement was made yesterday. The regulatory agency claimed that it would approve the consumption of meat from cloned livestock(家禽)in a scientific journal article published online earlier this month.
Consumer groups say labels are a must,because surveys have shown people are uncomfortable with the idea of eating meat from cloned livestock.
However,FDA regulators concluded that cloned animals were virtually indistinguishable from traditional livestock and that no special identification labels were needed.
“Labels should only be used if the quality of the meat is greatly changed by how it is produced,”said Barb Glenn of the Biotechnology Industry Organization.
Critics of cloning say the judgment is still out on the safety of food from cloned animals.
“Consumers are going to be buying a product that has potential safety problems and a whole load of ethical(伦理上的)issues tied to it, without any labeling”, said Joseph Mendelson,legal director of the Centre for Food Safety.
Carol Tucker Foreman,director of food policy at the Consumer Federation of America,said,“the FDA is ignoring research that shows cloning results in more deaths and deformed(畸形的)animals than other reproductive technologies. ”
The FDA scientists wrote that by the time clones reached six to eighteen months of age,they were almost the same as traditionally bred animals.
Final approval of cloned animals for food will be months away; the FDA will accept comments from the public after issuing a draft risk assessment(公布风险评估草案)yesterday.
Approval of cloned livestock has taken five years because big food companies are nervous that consumers might reject milk and meat from cloned animals.
67. What does the underlined word “it” in the second paragraph refer to?
A. The Food and Drug Administration.
B. The US Government.
C. An announcement.
D. A consumer.
68. Why do FDA regulators think it unnecessary to label the food from cloned animals?
A. Because they think it will take a lot of time.
B. Because they think it will waste a lot of paper.
C. Because they think the cloned animals are almost the same as the traditional ones.
D. Because they think the quality of the meat from the cloned animals has been changed.
69. When will the final approval of food from cloned animals come?
A. After the public accept cloned animal products.
B. After the government agrees to pass a bill.
C. After food from cloned animals is labeled.
D. After the FDA has assessed comments from the public.
70. Why has it taken 5 years to approve of food from cloned animals?
A. Because consumers may be afraid to buy the food from cloned animals.
B. Because big food companies are afraid that few consumers buy cloned animal products.
C. Because the Consumer Federation of America objected to approving the proposal.
D. Because the food from cloned animals is dangerous to eat.
67. 【解析】选A。词义理解题。从第二段第一句“食品药品管理局计划向工业集团发表讲话”,和第二句“该管理局已称它会批准……”可以判断,it指该管理局,即FDA。
68. 【解析】选C。细节理解题。由倒数第三段可知FDA的科学家们写道,克隆的时间达到6到18个月,它们几乎和传统方式饲养的动物相同。因此克隆动物的肉食没有必要标注商标。
69. 【解析】选D。推理判断题。由倒数第二段可知对克隆动物食品的最终批准是数月之后,美国食品药品管理局将接受公众对风险评估草案的意见。
70. 【解析】选B。细节理解题。由最后一段可知对克隆动物的食品的批准花费五年的时间,原因是大食品公司害怕消费者可能会拒绝这些食品。

Unlike Britain, the US does not have a national health care service. Most people buy medical insurance to help pay for medical care. The government only helps pay for some medical care for the old and the people who are on low incomes. The problems of those who cannot afford insurance have become an important political subject.
In Britain, when people are ill, they usually go to a family doctor first. However, people in America sometimes go straight to an expert. Children are usually taken to a doctor who is an expert in the treatment of children. In Britain, if a patient needs to see a specialist doctor, their family doctor will usually recommend a specialist, which will save more time and money both for the patients and the public fund(基金).
In Britain, doctors do not go to people’s homes when they are ill. People always make appointments to see the doctor in the doctor’s office. In a serious situation, people call for an ambulance. In America, hospitals must treat all seriously ill patients, even if they do not have medical insurance. The gov-ernment will then help pay for some of the cost of the medical care.
The majority of Americans pay for medical care .
A. through the national health care service B. by buying medical insurance

Have you ever walked outside thinking it was one temperature but quickly discovered it felt colder? That is because of the “wind chill” effect.
Wind chill is how cold people and animals feel when they are outside, not the actual temperature on the thermometer(温度计). It is based on how quickly your body loses heat when it is exposed to wind and cold. When the wind is strong, your body quickly loses heat, making the temperature of your skin drop.
When scientists first started calculating wind chill, they used research conducted in 1945 by explorers to Antarctica who measured how quickly water froze outside.
But water freezes faster than exposed skin, so the wind chill index based on that data wasn’t accurate.
In 2001, the US government began to measure wind chill more precisely by testing how quickly people’s skin froze.
Twelve volunteers were placed in a chilled wind tunnel. Equipment was stuck to their faces to measure the heat flow from their cheeks, forehead, nose and chin while they walked three miles per hour on a treadmill(跑步机).
The experiment revealed how quickly exposed skin can be damaged, particularly unprotected areas like your fingers, toes, the tip of your nose and your ear lobes. In fact, 40 percent of your body heat can be lost through your head! Signs you might have frostbite(冻疮) are when the skin turns white or pale and you lose feeling in that area.
The information collected from the volunteers helped scientists work out the math to compute wind chill. It involves wind speed and air temperature.
If, for example, the temperature outside is zero degrees Fahrenheit and the wind is blowing at 15 miles per hour, the wind chill is calculated at 19 degrees below zero. At that wind chill temperature, exposed skin can freeze in 30 minutes.
You can find a calculation table at www.nws.noaa.gov/om/windchill/index.shtml.
Experts advise in cold weather that you wear loose-fitting, lightweight, warm clothing, worn on top of each other. Air caught between the clothes will keep you warm. The best cold-weather coats have head coverings made of woven material that keep out water. So next time the temperature drops and you want to play outside, listen to your parents when they tell you to wrap up warm!
【小题1】 According to the text, wind chill _______.
A.means how fast exposed skin freezes |
B.doesn’t affect your head as much as other body parts |

B.Wind speed and a person’s strength. |
C.Air temperature and wind speed. |
D.The location and air temperature. |
A.It was in 1945 that scientists first began to calculate wind chill. |
B.Compared with water, people’s exposed skin freezes more slowly. |
C.The wind chill index based on Antarctica data is considered a standard. |
D.With the development of technology, many previous researches have been proven wrong. |
