【题目】 The negative health effects of sleep shortages during the week can’ t be changed by marathon weekend sleep sessions, according to a new study.

Researchers have long known that routine sleep deprivation(缺乏) can cause weight gain and increase other health risks, including diabetes. But there are still some people who hope that shutting off the alarm on Saturday and Sunday will repay the weekly sleep debt and remove any ill effects.

The research, published in Current Biology, ruins those hopes. Despite complete freedom to sleep in and nap during a weekend recovery period, participants in a sleep laboratory who were limited to five hours of sleep on weekdays gained nearly three pounds over two weeks and experienced metabolic disruption(代谢紊乱) that would increase their risk for diabetes over the long term. While weekend recovery sleep had some benefits after a single week of insufficient sleep, those gains were wiped out when people returned right to their same sleep schedule the next Monday.

“If there are benefits of catch-up sleep, they’ re gone when you go back to your routine. It’ s very short-lived,” said Kenneth Wright, who oversaw the research. “These health effects are long-term. It’ s kind of like smoking once was—people would smoke and wouldn’ t see an immediate effect on their health, but people will say now that smoking is not a healthy lifestyle choice. I think sleep is in the early phase of where smoking used to be.”

Wright said that the study suggests people should prioritize sleep—cutting out the optional “sleep stealers” such as watching television shows or spending time on electronic devices. Even when people don’t have a choice about losing sleep due to child-care responsibilities or job schedules, they should think about prioritizing sleep in the same way they would think about a healthy diet or exercise.

1What had the researchers already known before doing the new research?

A. The actual benefits of weekend recovery sleep.

B. Harm to health caused by the lack of routine sleep.

C. People’ s habit of shutting off the alarm during holidays.

D. The relationship between body weight and sleep amount.

2Kenneth Wright mentioned smoking to _________.

A. call on smokers to completely abandon smoking

B. advise people to go to sleep when they want to smoke

C. show people have known the harm brought by smoking

D. show people will someday notice the bad effects of sleep deprivation

3What does the underlined word “prioritize” in the last paragraph probably mean?

A. Putting tasks in order of importance.

B. Getting more than enough of something to deposit it.

C. Cutting down something that is not necessary any more.

D. Treating something as being more important than others.

4What can be the best title for the text?

A. Weekend catch-up sleep is a lie.

B. Bad sleep habits are harmful to health.

C. Smoking is not the worst thing to health.

D. A new study has an unexpected discovery.

【题目】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.
