“People are just likely to get sick from their phones as from handles of the bathroom, ” Jeffrey Cain, the president of the American Academy of Family Physicians , told The Wall Street Journal.
This may be hard to believe, but scientists reached this conclusion after they tested eight cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms (大肠菌), a kind of bacteria found in human waste , with about 2700 to 4200 units of the bacteria on each phone. The bacteria can cause flu, pinkeye and other diseases . That is right --- your phone is covered in our human waste.
Although computers, keys and pens carry germs (细菌) , our phones get far dirtier. They touch a lot of things, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn’t played Angry Birds or Fruit Ninja while sitting on the toilet?
“Some things that we think are personal are actually more public than we imagine,” Cain said. What is even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don’t think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease (油脂) , an environment that germs really like.
So how do you keep your phone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone’s surface: wash your hands regularly.

Probably every cook has his or her own way of cooking. But there are some basic skills that most people follow. For example, baking is a main method (方法) of preparing food in America. For that reason, Americans would find it next to impossible to live without an oven. American cooks pay special attention to the balance of foods, too. In planning a big meal they try to include meat, a few vegetables, some bread and often a dessert. They also like to make sure the meal is colorful. Having several different colors of food on the plate usually makes for a healthy meal.
For those who need guidance in their cooking, or for those who have just run out of ideas, recipes are a great help. Recipes list all the ingredients for a dish (generally in the order used), the amount of each to use, and a description of how to put them together.

A.Americans like to have several different colors of food on the plate |

First, vegetarians have an enormous health advantage. One of the major health problems in modern societies is not too much protein but too much fat, especially in the form of animal fats. Medical evidence suggests that animal fats, including butter, contribute to the development of cholesterol in the human body. High amount of cholesterol seem to be part of the cause of heart disease. Most vegetarians have low level of cholesterol. High amounts of animal fats also seem to lead to certain kinds of cancer, and vegetarians are typically less vulnerable to these cancers than people who eat a lot of meat. Overall, studies comparing the health of vegetarians and meat-eaters show that the meat-eaters are twice as likely to die of heart disease as vegetarians are.
Better health is one reason that people choose to become vegetarians. Another reason is religion. Some religions forbid the eating of meat. The largest of these is the Hindu religion, which has about 600 million believers in the world. Although not all Hindus are vegetarian, many are, and there are many believers of other religions such Buddhism and even some Christian religions that also do not eat meat.
Many vegetarians do not eat meat simply because they do not like the taste of it. They have no religious or philosophical reasons; they just do not like meat. Another important reason that vegetarians give for not eating meat is the health advantages that were given above. Lastly, there are many people who do not eat meat because they just do not like the idea of killing animals for food. They believe that life, all life, is valuable , and that we do not have to destroy life to feed ourselves when there are other good sources of food.
小题1:According to the passage, people choose to be vegetarians for the following reasons EXCEPT________.
A.they want to stay healthy |
B.they are too kind to put the idea of killing animals |
C.they live in areas where meat supply is not adequate |
D.they should not eat meat due to their religious belief |
A.Vegetarians enjoy a more healthy life than the meat eaters. |
B.Heart disease and cancer are caused by large amounts of protein. |
C.There are twice as many meat-eaters as vegetarians who die of cancer. |
D.There are less health problems in modern society due to advanced medical care. |
A.Having low level of cholesterol. |
B.Having high level of cholesterol. |
C.Having weak ability to resist diseases and harms. |
D.Having strong ability to resist disease and harms. |
A.being a vegetarian may be a very strange thing |
B.vegetarians eat meat on some special occasions |
C.all vegetarians have reasons for their not eating meat |
D.most vegetarians believe that life without meat is happy. |
The theme for 2013 is high blood pressure. High blood pressure increases the risk of heart attacks, strokes(中风). If left uncontrolled, high blood pressure can also cause blindness, irregularities of the heartbeat and heart failure. The risk of developing these complications is higher in the presence of other risk factors such as diabetes(糖尿病). One in three adults worldwide has high blood pressure and this increases with age, from 1 in 10 people in their 20s and 30s to 5 in 10 people in their 50s. High blood pressure is most common in some low-income countries in Africa, with over 40% of adults in many African countries thought to be affected.
However, high blood pressure is both preventable and treatable. In some developed countries, prevention and treatment of it has brought about a reduction in deaths from heart disease. The risk of developing high blood pressure can be reduced by: reducing salt intake; eating a balanced diet; avoiding harmful use of alcohol; taking regular physical activity; keeping a healthy body weight; and avoiding tobacco use.
The final and most important goal of World Health Day 2013 is to reduce heart attacks and strokes, which includes as follows:
1.to raise awareness of the causes and consequences of high blood pressure;
2.to provide information on how to prevent high blood pressure
3.to encourage adults to check their blood pressure and to follow the advice of health-care professionals.

C.Those who are in their 40s | D.Those who are in their 50s |
A.Less salt intake | B.Putting on weight | C.Regular exercise | D.No smoking |
A.the theme for World Health Day 2013 | B.the causes of high blood pressure |
C.the treatment of heart attacks and strokes | D.how to reduce the risk of high blood pressure |
Many people think that once you get infected by colds, you will not be easy to be attacked by colds for the rest of your life. That’s not the case. There are about 200 different viruses that cause the common cold. You catch a cold because of one kind of them this time, but you might catch a cold next time because of another.
Others believe that people get sick just because of the cold weather in winter. That is also wrong.
It’s because people tend to stay closer in winter and the cold virus is transmitted from one person to another through handshakes, sneezing, or coughing.
While there is no actual cure for the common cold, scientists say there are still a few things you can do to help you. Some experts say honey and chicken soup are effective against colds. Especially honey. There is increasing evidence that it helps shorten the duration of the common cold sometimes even by two to three days particularly in children. Chicken soup also helps reduce the duration of the cold.
In addition, if you do have a cold and you don’t feel like eating anything, it’s not going to hurt you but you have to drink a lot and you can drink water or tea because doctors say the water cycle in your bodies helps to cure colds. That’s very important. Though there is more than one way to deal with colds, doctors say the best advice is to continue using whatever works best for you.
小题1:We know from the second paragraph that ______.
A.the common cold is caused by only one virus |
B.there are people who never catch a cold |
C.colds can be caused by different viruses |
D.all people are easily attacked by colds |
A.passed | B.changed | C.cured | D.caused |
A.drinking a lot of water | B.drinking chicken soups |
C.eating honey | D.forcing yourself to eat |
A.now scientists have found out practical treatment for colds |
B.different people may have different ways to fight against colds |
C.working in freezing weather is the main reason for colds |
D.colds can be passed from animals to human beings |
