What time of day can you think most quickly? Are you a morning person? Or does it take you a few hours to get your brain going? A lot of recent research suggests that we should pay attention to our body clock. It can tell us what time of day we can perform best at.
Many people work best later in the morning. This is because the body’s temperature takes time to rise through the day. Taking a warm shower when you wake up can help your body’s temperature rise quickly.
But everyone’s body clock is different and some are special. Morning people will get up early and
work better early in the day. Evening people will work later but work better towards the end of the day. Research shows that we’re better at some activities at certain times of the day. Physical performance is at its best between 3 pm and 6 pm, so it’s better to exercise later in the day. 
Between noon and 4 pm, people begin to pay less attention. This is because we think less quickly
after a big meal. Research also shows we become sleepy around 2 pm. This is why people in Spain take a short sleep in early afternoon.  Finally, it is best to eat when we’re active. This allows our body
to burn calories better and stops our blood sugar levels from getting too high.

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 (李氏杆菌)in cheese and salmonella(沙门氏菌)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.
小题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
小题2:According to the passage, the new rules focus on_____.
A.inspecting the whole process of food production
B.improving food processing equipment on farms
C.preventing water pollution in food production
D.urging food companies to lay out plans
小题3:What does the word “they” in Paragraph 3 refer to?
A.Inspectors.B.Farmers
C.Manufacturers.D.Workers.
小题4:Which of the following is TRUE according to the passage?
A.The new regulations should have come into practice earlier.
B.The 2011 outbreak of listeria is the most serious ever.
C.Farmers and food companies are strongly against the new rules.
D.Colorado and New Mexico are worst hit by food pollution.

Cutting global warming pollution would not only make the planet healthier, it would make people healthier too, new research suggested.
Cutting carbon dioxide emissions could save millions of lives, mostly by reducing preventable deaths from heart and lung diseases, according to studies released Wednesday and published in a special issue of The Lancet, a British medical journal.
  "Relying on fossil fuels leads to unhealthy lifestyles, increasing our chances of getting sick and in some cases takes years from our lives," US Health and Human Services Secretary Kathleen Sebelius said in a telecast briefing from her home state of Kansas. "As greenhouse gas emissions go down, so do deaths from cardiovascular(心血管) and respiratory(呼吸道) diseases. This is not a small effect."
  Instead of looking at the health ills caused by future global warming, as past studies have done, this research looks at the immediate benefits of doing something about the problem, said Linda Birnbaum, director of the US National Institute of Environmental Health Sciences.
  Some possible benefits seemed highly speculative, the researchers conceded, based on people driving less and walking and cycling more. Other proposals studied were more concrete and achievable, such as reducing cook stoves that burn dung(粪便), charcoal and other polluting fuels in the developing world.
  And cutting carbon dioxide emissions also makes the air cleaner, reducing lung damage for millions of people, doctors said.
  "Here are ways you can attack major health problems at the same time as dealing with climate change," said lead author Dr. Paul Wilkinson, an environmental epidemiologist at the London School of Hygiene and Tropical Medicine.
  Wilkinson said the individual studies came up with numbers of premature deaths prevented or extra years of life added for certain places.
  For example, switching to low-polluting cars in London and Delhi, India, would save 160 lost years of life in London and nearly 1,700 in Delhi for every million residents, one study found. But if people also drove less and walked or biked more, those extra saved years would soar to more than 7,300 years in London and 12,500 years in Delhi because of less heart disease.
小题1:What does the passage mainly talk about? _______.
A.How can people live longer?
B.Cutting carbon dioxide emissions saves lives.
C.Global warming threatens people’s lives.
D.People should stop relying on fossil fuels.
小题2:The new research differs from past studies in that _______.
A.it focuses on the immediate benefits of cutting carbon dioxide emissions
B.it studies the bad effects arising from future global warming
C.it is believed by more people
D.it mainly targets at developing countries
小题3:According to Kathleen Sebelius, _______.
A.sometimes it takes years to see the bad effects caused by consuming fossil fuels
B.without greenhouse gas emissions, people would not die of cardiovascular and respiratory diseases
C.the main reason why people get sick is that they rely on fossil fuels
D.deaths from cardiovascular and respiratory diseases are closely related to greenhouse gas emissions
小题4: Which of the following is the most practical way to cut carbon dioxide emissions according to the passage? _________.
A.Driving less
B.Walking and cycling as much as possible.
C.Stopping using fossil fuels
D.Reducing the use of polluting fuels to cook.
小题5:It can be inferred from the passage that _____.
A.London and Delhi have already benefited from reducing greenhouse gas emissions
B.switching to low-polluting cars would save 160 lives in London each year
C.walking and biking instead of driving will reduce the chance of heart disease
D.attacking health problems and dealing with climate change are contradictory

In today"s fast-paced (快节奏) society, few people take time to enjoy the midday meal.Most of us just rush right through it. We grab a quick salad, or buy a sandwich and eat at our computers, Sometimes, if there is a deadline around the corner, we just skip lunch
The development of technology hasn"t done our eating habits much good either.We are constantly distracted by e-mail, social media, and 24 - hour news.Even when we do sit down for lunch, we are more connected to our hand - held electronic devices.
Long working hours can cause all kinds of health problems, and many developed countries have put in place labor laws specifically regarding the lunch break.These laws give employees the right to take a break during a long work shift, but it"s up to them whether they do so or not.
Frank Partnoy, a former Wall Street trader, says that employers should encourage workers to take time off for lunch.This is because long lunch breaks can benefit both individuals and society.
Writing in The Guardian, Partnoy says that one obvious reason to take a lunch break is to slow down and gain some perspective(认识). A break from work allows us to think strategically and outside the box.It also puts our daily tasks into a broader context(背景).
What we eat at lunch is also important.In Partnoy" s opinion, a fast food lunch is more harmful than not having lunch at all.  And it"s not just about calories and unhealthy food.Recent studies show that fast food also has negative effects on how we think.
However, if we sit down at a proper restaurant and chat leisurely with colleagues, we are more likely to slow down, something that hardly can be achieved in a noisy and over — packed fast food chain.
Despite these benefits, some employees might still be unwilling to take time off for lunch.Partnoy"s suggestion? Make skipping lunch difficult: Employers could ask workers to fill out a form stating their reasons for skipping the meal.
小题1:What does the underlined phrase "skip lunch" mean in the first paragraph?
A.have a quick lunchB.don"t have lunch
C.work while having lunchD.take a lunch break
小题2:Which of the following is true according to the text?
A.Modern technology results in good diet habits.
B.Electronic devices make our life comfortable.
C.Many people are too busy to have a good lunch.
D.Laws have passed to make workers have lunch.
小题3:According to Frank Partnoy, long lunch breaks            .
A.are time for the workers to relax their mind
B.make the employees work longer hours
C.are for employees to have a quick lunch
D.make the workers eat a proper lunch at home
小题4:In Partnoy"s opinion, a fast food lunch                .
A.saves a lot of time for a rest
B.affects people"s way of thinking
C.is better than having no lunch
D.makes workers sit down and think
小题5:What might be the author"s purpose in writing the text?
A.To warn us not to eat fast food.
B.To introduce Frank Partnoy"s opinion.
C.To encourage us to work more efficiently.
D.To show the importance of a proper lunch.

Every hour spent in watching TV, DVDs and videos as an adult reduces lifespan by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years.
The research shows that a sedentary(久坐的) lifestyle is as bad for health as smoking and obesity, because of the dangers caused by inactivity and the greater opportunities it offers for unhealthy eating.
The researchers set out to calculate the overall risk to lifespan from watching television. Their research involved more than 11,000 people over the age of 25.
Writing in the British Journal of Sports Medicine, they concluded. "TV viewing time may be connected with a loss of life, which is similar to other major chronic disease risk factors such as physical inactivity and obesity."
The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data.
But they said: "Although we used Australian data, the effects in other industrialized and developing countries are likely to be similar, considering the large amounts of time spent watching TV and similarities in disease patterns." In the United Kingdom, the average amount of time spent watching TV is four hours a day, compared with five hours in the United States.
Earlier this year, a separate study suggested the risk of developing diabetes and heart disease, or dying early, rises by as much as 20 percent after just two hours a day in front of the box.
England"s Chief Medical Officer, Sally Davies, said: "Physical activity offers huge benefits and these studies back what we already know - that a sedentary lifestyle carries additional risks. We hope these studies will help more people realize that there are many ways to get exercise."
小题1:We can learn from the passage that       .
A.whether you watch TV or not has nothing to do with how long you will live
B.if an adult watches TV for six hours every day, he will probably die five years earlier
C.physical inactivity and obesity won"t shorten your life
D.a sedentary lifestyle offers huge benefits.
小题2:The passage implies that _______.
A.The longer one watches TV every day, the shorter he lives.
B.The conclusion of the study is unbelievable because it"s based on Australian data.
C.Watching TV does greater harm to health than smoking and obesity
D.Watching TV harms children as much as adults.
小题3:What do we know from the last three paragraphs?
A.People in the United Kingdom watch TV longer than those in the United States.
B.That a sedentary lifestyle carries additional risks isn"t supported by other studies.
C.Watching TV for two hours a day will increase the risk of illnesses or dying early by 20%.
D.Australian data is much different from that of other countries.
小题4:The passage is intended to _______.
A.inform the readers of a research on watching TV
B.tell the readers large amounts of people often watch TV
C.tell the readers watching TV is also a good way to relax
D.warn the readers of the harm of watching TV and hope that they do sports
