Want to stay away from colds? Put on a happy face.
Compared to unhappy people, those who are cheerful and relaxed are less likely to suffer from colds, according to a new study. It's possible that being happy helps the body fight illnesses, say the researchers from New York University.
"It seems that positive feelings may reduce the danger of illness," said the study's chief researcher Sheldon Cohen.
In an earlier study, Cohen found that people who were cheerful and lively caught coughs and colds less often. People who showed feelings were also less likely to tell their doctors that they felt ill.
In this study, Cohen's interviewed 193 adults every day for two weeks. During the interviews, the people were given colds by doctors and had to stay alone in a room for six days.
The results showed that everyone in the study was equally likely to get ill. But for people who said they felt happy during the research period, their illness are less serious and lasted for a shorter time.
Cohen believes that when people experience positive feelings, their body may produce a chemical that helps fight illness and disease. So if you are worried about your health, look on the bright side more often.
小題1:Which of the following was NOT a part of the study?
A.People talked about their feelings every day.
B.People were kept alone for six days.
C.People were given colds by doctors.
D.People were made to feel unhappy.
小題2:What did the study find?
A.People who felt happy never got ill.
B.People's feelings didn't influence their health.
C.People with good feelings became ill more easily.
D.People with positive feelings had less serious illnesses..
小題3:According to Cohen, which of the following may help fight illness?
A.Eating.B.Crying.C.Laughing.D.Sleeping.

正誤判斷
In the United States, children start school when they are five years old. In some states they must stay in school until they are sixteen. Most students are seventeen or eighteen years old when they leave secondary(中等的) schools. There are two kinds of schools in the United States: public schools and private(私立的)schools . Most children go to public schools. Their parents do not have to pay for their education because the schools receive money from the government. If a child goes to a private school, his parents have to get enough money for his schooling. Some parents still prefer private schools, though they are much more expensive. Today about half of the high school students go to universities after they finish the secondary school. A student at state university does not have to pay very much if his parents live in that state. But many students work while they are studying at universities. In this way they develop good working habits and live by their own hands.
小題1:Children can go to school at the age of four in the U.S.
小題2:Most parents prefer to send their children to private schools in America.
小題3:About fifty percent of high school students can go on to universities after they leave the secondary school today.
小題4:Lots of American students go to universities by depending on their parents completely (完全地).
小題5:The passage is mainly about American education.

Answer the questions(根據短文內容回答下列問題)
Your Nose is Busy and Important
Your nose has many important jobs, and is always busy.
Smelling
Smelling helps you gather information about the world around you. A good scent (氣體),like flowers, brings you pleasure. A bad scent, like smoke or sour milk, warns you of danger. Most things around you release scent particles (微粒) into the air. These invisible chemicals enter the nose when you breathe. Nerves in the nose send information to the brain to identify a smell. You are able to recognize thousands of smells.
Breathing
Most of the air you breathe enters through your nose. The nose uses hair and mucus (粘液) to clean dust and germs (細菌) out of the air. The air that enters your nose contains oxygen. Your body uses oxygen to unlock the energy in the food you eat.  Even when you sleep, your body needs energy to keep your heart beating and your brain working.
Tasting
Your nose helps you enjoy food. Flavor is a mixture of taste and smell. The smell of the food helps you identify what you are eating. The sense of smell contributes more to (貢獻) food flavor than the sense of taste .When you are sick and have a stuffy nose, your food doesn’t taste as good because without smell, food loses most of its flavor.
Smell memory
Smells can bring back memories. Your brain uses a process to create a picture in your mind from the odors(氣味)you smell. Smells can affect your feelings because the part of the brain that helps you identify smells is close to the area that affects your emotions, mood and memory. More smell memories are collected as you get older.
Your nose has many important jobs, and is more than just a smeller!
小題1:How many important jobs does a nose do according to the passage? What are they?
小題2:Smelling helps you recognize thousands of smells, doesn’t it?
小題3:What does the nose use to clean dust and germs out of air?
小題4:What happens to your food if you are sick and have a stuffy nose?
小題5:How do smells bring back memories?
小題6:What do you think of your nose? Why do you think so?

It is said that the eyes are the windows of our soul. Beautiful and bright eyes not only show a good health but also make you look very attractive. However, to have healthy eyes you have to look after them properly. Your eyes need everyday attention.
Pay more attention to your diet. First, eat food that is good for your eyes. They are fresh fruits and vegetables as fish, eggs, and milk. Besides, a regular amount of vitamins A and B2 should also be taken.

Don’t read or write in poor or bright sunlight. Always use sunglasses as sunlight can cause eye tiredness. Light should not shine directly in your eyes. Too much reading, writing, watching television or working on the computer can also cause eye tiredness.

Swimming and English Learning
Can you swim? Do you like swimming? Yes? Well, how can you learn to swim? I think the best way is to go into the water and learn. I’m afraid you’ll never learn to swim just by reading books about swimming or looking at others swimming. It’s the same with the English study. We must practice, practice and practice.
Listening and speaking are very important for beginners. The children in English-speaking countries first listen to others. Then they try to imitate and speak. We can listen to English programs on radio. You may just understand a few words. It doesn’t matter. Just be relaxed, try to catch every word.
Somebody may be a good listener. But he dare not speak. He’s afraid of making mistakes. You know we sometimes make mistakes when we speak Chinese. Don’t be afraid. We must be brave(勇敢). If you really want to learn English well, you must try to speak with everyone so long as he knows English. Whether you know him or not is not important when there’s nobody to talk with, you can talk to yourself in English. It’s interesting and also a good way to practice your spoken English. Remember, the more you speak, the fewer mistakes you’ll make.
Reading and writing are more important for senior school students. First we must choose the books we’re interested in. A lot of reading will improve your language sense. This is the most important.
Keep writing English diaries. We can also write English articles. You may even post them to English magazines. Don’t be afraid of failure. Failure is the mother of success.
Easier said than done. Well, let’s do more practice from now on. I’m sure you’ll learn English well in this way.
(   ) 6. You can learn to swim by_______.
A. reading books about it  B. looking at others swimming
C. having lessons on it    D. going into the river and learning
(   ) 7. We should learn English by _______.

C. A and B                  D. swimming
(   ) 8. What will you do with mistakes when you speak?
A. Don’t make mistakes.          B. Study hard
C. Try not to speak English        D. Don’t be afraid.
(   )9. What’s more important for senior school students?
A. listening    B. speaking    C. reading and writing   D. learning
