Have you ever had a headache during a test? Have you ever been too worried about something that you have a headache or even can’t sleep at night? If so, then you know that stress is.

Not all stress is bad for you. Some kinds of stress can help you get things do better, like when you are running towards the finishing line or when you are being asked to give a speech to your class. Stress sometimes can help push you to make full preparation for a test. However, too much stress can result in anger, depression and other related problems, which we need to take serious.

There are many things in our life what might cause stress — having too much homework, taking a difficult test, and having economic problems.

It’s impossible to live in a life completely free of stress, so you should learn to deal with stress. The best way reduce stress is to have a balance life. If you get enough sleep, eat properly, take more exercise and have enough fun time, you’ll probably feel less stressed.

Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

___1.___ Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.

For years many doctors thought that repressing anger was more dangerous to a person’s health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙). They speed the heart rate, raise blood pressure, or sugar into the blood, etc. __2.___

Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep anger inside may face a greater danger of high blood pressure.

___3.__ They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “___4.___ Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. ___5.___

A. In general the person feels excited and ready to act.

B. They said that laughter is much healthier than anger.

C. Expressing anger violently is more harmful than repressing it.

D. Anger may cause you a cancer.

E. Do not express your anger while angry.

F. Anger is a normal emotion that we all feel from time to time.

G. Doctors say the solution is learning how to deal with anger.

Scientists have devised a way to determine roughly where a person has lived using a strand (缕) of hair, a technique that could help track the movements of criminal suspects or unidentified murder victims.

The method relies on measuring how chemical variations in drinking water show up in people’s hair.

“You’re what you eat and drink, and that’s recorded in your hair,” said Thure Cerling, a geologist at the University of Utah.

While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move.

Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes (同位素). The heaviest rain falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah.

Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months.

Cerling’s team collected tap water samples from 600 cities and constructed a map of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of rain systems.

“It’s not good for pinpointing(精确定位),” Cerling said. “It’s good for eliminating many possibilities.”

Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake.

The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair.

When Park heard about the research, he gave the hair samples to the researchers.

Chemical testing showed that over the two years before her death, she moved about every two months.

She stayed in the Northwest, although the test could not be more specific than somewhere between eastern Oregon and western Wyoming.

“It’s still a substantial area,” Park said “But it narrows it way down for me.”

1.What is the scientists’ new discovery?

A. One’s hair growth has to do with the amount of water they drink.

B. A person’s hair may reveal where they have lived.

C. Hair analysis accurately identifies criminal suspects.

D. The chemical composition of hair varies from person to person.

2.What does the author mean by “You’re what you eat and drink” (Line 1, Para.3)?

A. Food and drink affect one’s personality development.

B. Food and drink preferences vary with individuals.

C. Food and drink leave traces in one’s body tissues.

D. Food and drink are essential to one’s existence.

3.What did Cerling’s team produce in their research?

A. A map showing the regional differences of tap water.

B. A collection of hair samples from various barber shops.

C. A method to measure the amount of water in human hair.

D. A chart illustrating the movement of the rain system.

4.What is the practical value of Cerling’s research?

A. It helps analyze the quality of water in different regions.

B. It helps the police determine where a crime is committed.

C. It helps the police narrow down possibilities in detective work.

D. It helps identify the drinking habits of the person under investigation.

I’ve often wondered how exactly sleep, or lack of it, can have such an awful effect on our bodies and, guess what, how much we sleep switches good genes(基因) on and had genes off.

In the first half of 2013, the Sleep Research Centre at the University of Surrey found a direct link between hours spent sleeping and genes. Every cell in our bodies carries genetic instructions in our DNA that act as a kind of operating handbook. However, each cell only “reads” the part of this handbook it needs at any given moment.

Can sleep affect how a gene reads instructions? It’s a question asked by Professor Derk-Jan Dijk at the University of Surrey. He set up an experiment and asked his volunteers to spend a week sleeping around seven and a half hours to eight hours a night and the next sleeping six and a half to seven hours.

Blood samples were taken each week to compare which genes in blood cells were being used during the long and short nights. The results were rather surprising. Several hundred genes changed in the amount they were being used, including some that are linked to heart disease, cancer, and Type 2 diabetes. Genes to do with cell repair and replacement were used much less.

Sleep restriction(six and a half to seven hours a night) changed 380 genes. Of these, 220 genes were down regulated (their power was increased). Those affected included body-clock genes which are linked to diabetes(糖尿病). One of the most downgraded genes is that which has a role in controlling insulin(胰岛素) and is linked to diabetes and insomnia(失眠). The most upgraded gene is linked to heart disease.

So changing sleep by tiny amounts can upgrade or downgrade genes that can influence our health and the diseases we suffer from when we sleep too little.

The important message is that getting close to eight hours of sleep a night can make a dramatic difference to our health in just a few days through the way it looks after our genes.

1.What kind of relation is directly discussed in the passage?

A. Sleeping hours and changes of genes.

B. Sleeping hours and diseases.

C. Changes of genes and diseases.

D. Genes and health.

2.What can we learn about Professor Derk-Jan Kijk’s experiment?

A. The experiment was carried out to find the answer to how genes affect sleep.

B. The experiment took a period of more than two weeks to reach a conclusion.

C. His volunteers were divided into two groups with two different sleeping patterns.

D. Blood samples of the volunteers were checked afterwards to decide how many genes changed in sleeping.

3.Which of the following may be concluded from the passage?

A. The experiment was performed at the University of Surrey in early 2013.

B. Body-clock genes are associated with heart disease, cancer and Type 2 diabetes.

C. Sleep restrictions may contribute to disease like diabetes, insomnia, and heart disease.

D. 7.5-8 hours’ sleep pattern makes little difference compared with 6.5-7 hours’ sleep pattern.

4.Which of the following can be inferred from the findings of the sleep research?

A. When there is a sleep restriction, genes to do with cell repair and replacement function less.

B. In a sleep, several hundred genes change in the amount. The more changes, the worse results.

C. When genes are up regulated, they do good to health; when genes are down regulated , they do harm to health.

D. Eight hours of sleep a day can be beneficial to our health in that it looks after our genes.

House Sitting

In many countries of the world people do what is called house sitting. It means that if owners of the house are going away, they want someone to come into their home and look after the house and maybe pets while they are away.

In Australia, many people travel. After people retire, they might buy a van and travel all over the country. 1.

So if someone wants to travel or go away for some reason, they might want someone in their home to care for it and keep the gardens tidy. House sitters might have to care for pets. Also, quite a few people have swimming pools in their back yard and they need cleaning. 2. I feel it is a great way of seeing the country, because you go and stay in a new city, get to meet new people, and have time to go sightseeing in a new area.

3. There are websites where you find the advertisements by people who want to travel, and by replying to the advertisement, you can make arrangements to go and look after their home.

There are some requirements to be a house sitter. You must be a trusted person, so that the home owner knows you will not steal anything. You must be able to go when the house owner wants you to go, so you need lots of free time. 4. You need to be good with pets, able to care for cats and dogs, or other pets they may have.

Some house sitting jobs are just for a few days or a couple of weeks while the house owners have a short holiday. Sometimes it is for much longer. We have had one house sit for six months, while the home owner travelled to Europe.

5. Then you can travel to many different countries and stay there. One of the important things to get is references from the home owners where you have stayed. A reference is a written letter to say that you are trustworthy and have looked after their home well. You can show these letters to possible house sitting jobs and they know you will do a good job.

A. I have done house sitting many times.

B. Thousands of people do this all the time.

C. It is also possible to do house sitting in other countries.

D. Generally you have many opportunities to get a house sitting job.

E. You must take a little care over what your description says about you.

F. This is an international house sitting service for all city and country areas.

G. You must have a good car, so you can travel to different parts of the country.
