People who do not get enough vitamin C may feel tired. Their legs may hurt. Their gums (牙龈) may begin to bleed and even fall out. These are the symptoms of scurvy (坏血病). In the 1800s, sailors often spent long time at sea. That's why many developed scurvy.
While looking for more information about scurvy, 14 year old Amber Cui saw some dietary guidelines that recommended eating vitamin C rich fruits and vegetables raw. Amber hates raw green peppers, but doesn't mind them cooked. So she began to wonder what cooking does to vitamin C levels of vegetables.
Raw peppers indeed had the most vitamin C, she found. Ten minutes of boiling reduced the vitamin C level by about 25 percent. But as the peppers were boiled for 20 or 30 minutes, she says, the vitamin C level began to rise again. This might be because after being boiled for that long, the peppers begin to lose water. That could concentrate (浓缩) the vitamin in the vegetable.
Most people probably don't blend their peppers before they eat them. But we do chew and digest them. That's how the body is able to break down the hard cell walls of plants to approach their vitamins, notes Anitra Carr. She studies the health effects of vitamin C at the University of Otago in Christchurch, New Zealand.
Amber's pepper results are similar to other scientific findings, Carr says. “The amount of vitamin C in foods generally decreases with cooking，” she notes. The vitamin can go into the water in which peppers are cooked. Heat and other chemical processes can also break it down.
But we might still get more vitamin C from some cooked vegetables than raw, Carr says. How Cooking or blending can soften and break up plant cell walls, she explains. This can make it easier for the body to use the vitamins inside.

If you are driving with a minor (未成年人), smoking a cigarette could get expensive. About six states have already banned smoking in cars with kids. And Washington may be next.
House Bill 2086 is trying to ban anyone from lighting a cigarette while parking or driving if there is someone under 18 in the car.
“Harmful chemicals that are coming out of someone smoking in a car are the same as a firefighter fighting a forest fire for four to eight hours，” said state Representative Steve Bergquist.
Supporters of the Bill say they want to protect the quarter million Washington kids who live with smokers. “Research shows that kids of smokers are twice as likely to become smokers themselves. I am one of those children，” said Meagan Darrow, director of the Lacey based TOGETHER. “We also know it's an asthma trigger (哮喘触发); 10 percent of our kids in our state have asthma.”
The fine would be $125 for the first offense, and additional violations (违反) could be double. It would not show up on a driver's record or be reported to an insurance company but some say the government is still going too far.
If it is passed, that means police officers could simply pull someone over if they see someone smoking and they think a minor is in the car.
“When I see someone smoking with a kid in the car, I feel bad for the kids. But, on the other hand, it's one of those issues，” Thurston County resident Debra Defreyn said. “That's like coming to my house to tell me I can't do something in my house.”
语篇解读：孩子坐在车里，有大人吸烟，你是不是担心他们的健康呢？《2086议会议案》禁止任何人在有孩子的车内吸烟。
5．House Bill 2086 is intended to ________.
A．ban smoking in public places

6．According to the passage, ________.
A．driving with minors will be very dangerous
B．four million Washington kids live with smokers
C．smoking in a car is extremely bad for children's health
D．Washington will be the seventh state to ban smoking in cars
解析：选C 细节理解题。根据第三段“Harmful chemicals that are coming out of someone smoking in a car are the same as a firefighter fighting a forest fire for four to eight hours”可知，车内吸烟所产生的有害化学物质等同于一个消防人员扑救森林火灾4到8小时，故车内吸烟严重影响孩子们的健康。
7．What can we learn from Meagan Darrow's words
A．His parents are probably smokers.
B．He is strongly against House Bill 2086.
C．He has successfully given up smoking.
D．He suffers from asthma caused by smoking.
解析：选A 细节理解题。根据第四段“‘Research shows that kids of smokers are twice as likely to become smokers themselves. I am one of those children，’ said Meagan Darrow”可知，研究表明，吸烟人的孩子自己成为吸烟者的几率更大。Meagan Darrow说他就是这些孩子中的一员。故Meagan Darrow的父母可能是吸烟者。
8．Debra Defreyn thinks House Bill 2086________.
A．is very bad for children
B．is a safety measure for drivers
C．will be passed in the near future
D．limits people's freedom in a way
解析：选D 推理判断题。根据最后一段“That's like coming to my house to tell me I can't do something in my house.”可知，Debra Defreyn认为这就好像进入他家，告诉他不能在他的房子里做什么一样。故可推知，Debra Defreyn认为这项议案干涉了人们的生活，限制了人们的自由。

Ⅲ.阅读理解
There has been a lot of concern about the health risks linked with today's more sedentary (久坐的) lifestyle. When it comes to your health, sitting too much may be as bad for you as smoking. Many office workers spend a large part of their time being seated and physically inactive. A lack of physical activity is linked to some 5.3 million deaths worldwide each year. A sedentary lifestyle can cause many diseases, including heart disease, diabetes (糖尿病) and even some cancers.
“For many people who commute (通勤) to work and have office based jobs, there is no way to escape sitting for long periods of time. But an hour of brisk (轻快的) exercise every day can help office workers reduce their risk of an early death，” Ekelund from the Norwegian School of Sports Sciences says.
Ekelund says he “cannot stress enough” the importance of getting exercise and suggests going for a run in the morning, riding a bicycle to work, or taking a walk in the middle of the work day. An hour of physical activity is ideal. But if this is not possible, he suggests doing at least some exercise each day to reduce the risk of disease and an early death.
Ekelund looked at 13 earlier studies on the effect of inactivity. Study subjects were grouped according to the amount of activity they reported, from less than 5 minutes a day to up to 75 minutes a day. Ekelund found those who sat for eight hours a day, but got the suggested amount of exercise reduced their chances of dying at an early age. These people did better than those who sat less but were not active.
Ekelund says, “It is possible to reduce, or even remove, these risks if we are active enough, even without taking up sports or going to the gym.”
语篇解读：在办公室久坐的人只要每天进行适量的锻炼就可减少或消除患病或早亡的风险。
1．We can know from the passage that ________.
A．most diseases are related to the sedentary lifestyle
B．people should consider how to reduce office work
C．sitting long is the biggest health risk for office workers
D．some people have realized the danger of sitting for too long a time
解析：选D 推理判断题。根据第一段“There has been a lot of concern about the health risks linked with today's more sedentary (久坐的) lifestyle.”可知，现在有很多关于久坐的生活方式导致健康风险的担忧。由此可推知，一些人已经意识到了久坐的风险。
2．According to Ekelund, for many office workers, ______.
A．sitting for too long a time is unavoidable
B．they should change their way of working
C．they have to do exercise during the break time
D．there is no way to get enough exercise every day
解析：选A 细节理解题。根据第二段“For many people who commute (通勤) to work and have office based jobs, there is no way to escape sitting for long periods of time.”可知，对于许多办公室一族来说，久坐是不可避免的。
3．What's office workers' practical way to reduce the risk of disease
A．Going to the gym every day.
B．Keeping physically active every day.
C．Taking up a competitive sport.
D．Having at least an hour of exercise every day.
解析：选B 细节理解题。根据第三段可知，Ekelund建议久坐的办公室一族可以在早上跑步、骑自行车上班，或在工作日的中午散步。一个小时的体育活动是理想的。但如果达不到的话，他建议每天至少做一些运动，以减少疾病和早亡的风险。结合最后一段可知，只要我们保持运动，减少甚至消除这些风险都是有可能的，我们甚至都不需要专门参加一些体育运动项目或去健身房。由此可知答案。
4．What kind of office worker is most likely to risk an early death
A．Those who do some exercise without keeping it every day.
B．Those who have light exercise but without strength training.
C．Those who sit for a short time but with no exercise every day.
D．Those who sit longer with a suggested amount of exercise every day.
解析：选C 细节理解题。根据倒数第二段“Ekelund found those who sat for eight hours a day, but got the suggested amount of exercise reduced their chances of dying at an early age. These people did better than those who sat less but were not active.”可知，那些虽然坐的时间短，但每天不参加任何运动者最可能有早亡的风险。

Should states ban junk food in schools
In response to rising obesity rates nationally, 16 states have recently adopted school nutrition policies.But people's opinions vary.
Richard J．Codey, acting governor of New Jersey, supports the policies.He said, “America is facing a crisis (危机) because of our eating habits.__1__ Nearly 300,000 people die each year from complications (并发症) associated with being obese or overweight.
Poor eating habits developed at an early age lead to a lifetime of real health consequences.School is where children spend most of their time, and it's where we lay the foundation for healthy habits.__2__
If you go to school in New Jersey, school stores will no longer be able to sell snacks that are high in fat and loaded with sugar.__3__
Obesity is a health problem across our country, and we have a responsibility as a government and a society to do all we can to promote good nutrition and healthy eating so we can change this alarming trend.”
However, John Dively, executive director of Illinois Principals Association disagrees.
“It may make sense for a school board to ban junk food in some cases, but there are several issues that should be considered.
__4__ Are we talking about potato chips, soda, and pastries What about fried chicken fingers, cheeseburgers, and pizza — foods many school cafeterias serve
Second, an important part of education is learning to make good choices.An across the board junk food ban does not teach young people how to make healthy choices.__5__
Third, improving what we teach about nutrition and requiring more physical activity are better ways to approach obesity than placing statewide junk food bans.”
A．Sixty million adults are obese.
B．It simply removes some of their options.
C．Childhood obesity is a very serious issue.
D．To begin with, there is the problem of defining junk food.
E．Soda and junk food will be replaced with more nutritious alternatives.
F．That's why New Jersey has adopted a school nutrition policy that bans junk food.
G．The American education system is designed to give communities control over their schools.
语篇解读：本文是议论文。文章主要讨论了美国是否应该在校园内禁止垃圾食品。
1．解析：选A 由该空前的“America is facing a crisis (危机) ...”以及该空后的“Nearly 300,000 people die ...being obese or overweight.”可知，A项“六千万成年人都是肥胖的”符合此处语境。
2．解析：选F 由该空前的“School is where children ...lay the foundation for healthy habits.”以及下文的描述可知，这就是为什么新泽西州已经通过了在学校里禁止垃圾食品的营养政策。
3．解析：选E 由该空前的“school stores will no longer be able to sell snacks that are high in fat and loaded with sugar”可知，本段主要讲述禁止垃圾食品的营养政策的具体举措，故E项“汽水和垃圾食品将会被更有营养的食物取代”符合此处语境。
4．解析：选D 由上文中的“there are several issues that should be considered”和下文中“Second, an important ...”以及该空后的描述可知，首先的问题是如何定义垃圾食品。
5．解析：选B B项中的“options”与该段中的“choices”相呼应。John Dively认为教育的一个重要部分是让学生学会做出正确的选择，而在校园里禁止垃圾食品并没有教学生如何做健康的选择，而只是删去了一些选择。课时跟踪检测（四）Project

Health experts are calling for action to increase cancer care and control in developing countries. A medical research paper says cancer was once thought of as a problem mostly in developed countries. But now cancer is a leading cause of death and disability in poor countries as well. Experts from Harvard University and other organizations urge the international community to fight cancer actively, saying it should be fought in the way HIV/AIDS has been fought in Africa.
Cancer kills more than 7.5 million people a year worldwide. Almost two thirds are in the low income and middle income countries.
They discover cancer kills more people in developing countries than AIDS, tuberculosis (结核病) and malaria (疟疾) combined. But the world spends only 5% of its cancer resources in those countries.
Felicia Knaul from Harvard Medical School was one of the writers of the paper. She was in Mexico when she was found to have breast cancer. She received treatment there and her experience showed her the sharp difference between the rich and the poor in treating breast cancer.
Felicia Knaul says, “And we are seeing how this is attacking young women. It's the number two cause of death in Mexico for women thirty to fifty four. All over the developing countries, it's the number one cancer related death among young women. I think we have to again say that there is much more we could do about it than we are doing about it.”

Ⅳ.阅读理解
Scientists have discovered that tea contains high levels of compounds that help to reduce the amount of fat absorbed by the gut (内脏) and can cut cholesterol (胆固醇). However, proteins found in cows' milk prevent this fat fighting ability.
New research has shown that the compounds, called theaflavins and thearubigins, prevent obesity when given to rats that were also on a high fat diet. The researchers now believe this could explain why people in Britain appear not to benefit from the healthy effects of tea despite being among the world's biggest consumers of the beverage.
Dr Devajit Borthakur, a scientist at the Tea Research Association, in Jorhat, India said, “When tea is taken with milk, theaflavins and thearubigins form complexes with the milk protein, which causes them to precipitate (沉淀)”．
Scientists at the research center are now working on developing new kinds of tea with higher levels of these compounds, which are known as polyphenols, while also looking for ways of making them less influenced by milk.
A study by scientists in Japan, which was published this month in the journal of Nutrition, reveals that extracts from tea leaves prevent the absorption of fat in the gut of rats fed with high fat diets. These rats also had less fat tissue on their bodies and lower fat content in their livers.
Dr Hiroaki Yajima, a scientist with the Kirin Beverage Company in Japan who carried out the Japanese research, said, “Black tea extracts may prevent obesity because of eating too much by preventing intestinal lipid (肠脂) absorption.”
The fermentation (发酵) process used to make “black” tea leaves, the most commonly drunk type of tea in the UK, has also been found to boost levels of these fat fighting compounds compared to green tea, which is unfermented.
The research suggests that despite more attention being paid to the health benefits of green tea, black tea may have better effects on our health which are reduced by the tendency to drink it with milk.

In defence of free health care
Health care is regarded as an important way to improve the health and well being of people around the world. In many countries of the world, free health care is provided by the government. __1__ Clearly, we all have to pay for this service through our taxes (税款)．
__2__ They say that people who take unnecessary risks should not receive this free health care. For example, people who join in risky activities such as skiing are more likely to have an accident. It has been suggested that these people should pay for any medical treatment they require.
__3__ Firstly, it's difficult to say exactly what is risky and what is not. For example, not doing enough exercise is probably more risky than skiing in the long term. As a result, it isn't fair to give free health care to an inactive person and make the skier pay. __4__ Clearly, these people should receive free medical treatment if they are hurt on the job.
Finally, I would like to say that I think free health care is a good thing. I understand that the system is not perfectly fair because some people use it more than others. Besides, not all the medical treatment is really necessary for the health of the patient. The taxpayer should not have to pay the costs of such treatment. __5__
A．It helps you make money.
B．Personally, I disagree with this point of view.
C．However, some people think this is basically unjust.
D．This means that everybody has a chance to see a doctor.
E．Free health care will decrease the economy of the country.
F．Besides, fire fighters take risks, but they are necessary risks.
G．However, in my opinion, this is a small price to pay for a healthier society.
语篇解读：本文是议论文。文章主要谈论了作者对政府推出的免费医疗制度的看法。

2．解析：选C 根据下一句中的“They say that people who take unnecessary risks should not receive this free health care”可知，有些人认为免费医疗制度不公平，那些参与冒险活动的人不应该享受免费医疗政策。
3．解析：选B 根据下一句中的“Firstly, it's difficult to say exactly what is risky and what is not” 可知，“我”不同意第二段中所提到的观点。
4．解析：选F 根据下一句中的“Clearly, these people should receive free medical treatment if they are hurt on the job”可知，消防员因公受伤后显然需要接受免费治疗，因为他们承担了不可避免的危险。
5．解析：选G 根据最后一段中的“I think free health care is a good thing. I understand that the system is not perfectly fair”，及下面谈论的免费医疗制度的一些不足之处可知，“我”认为这些不公平只是为一个更健康的社会付出的小代价。
