Does stress cause gray hair? Many people believe that tension and stress can cause your hair to lose its color. In fact, it is an old-wives’ tale that being upset all the time can result in premature graying. Here is a closer look at this situation and why some believe that this old wives’ tale could be true.
As one ages, the hairs on the head also age. In fact, just about everything on the human body begins to show signs of wear and tear (磨损) after a while. The joints wear and become stiff and skin wears and becomes wrinkled. Hairs on the head grow and eventually die. They are replaced, but in the process something else happens.
When new hairs are replacing the old ones, the color or pigment (色素) is also added to them. However, as one ages, this pigment becomes less and less available. At first, hairs will have a limited amount of pigment and they will appear to be grayish in color. In time, they will lose all of their pigment and will be white. Many things are known to cause graying, and genetics is a very powerful factor. If one of your parents turns gray at an early age, there is a good chance that you will too. Some people begin the graying process in high school, while others may be over the age of forty.
Constant worry and tension can have many harmful effects on the human body. It is a known fact that stressful times can cause one to suffer hair loss. It would make sense that if it can cause these problems, perhaps it also may contribute to graying. However, there is no sound evidence to support this.
On the other hand, many medical professionals believe that there may be a link between graying and a constant state of anxiety or tension. Does stress cause gray hair? There is no scientific evidence to support the theory, but it is best to avoid stressful situations.
1.The underlined phrase in the first paragraph most probably means________.
A.clever remarks B.silly remarks C.exciting remarks D.disappointed remarks
2.The second paragraph mainly tells us __________.
A.every part of body is replaced with age B.hairs will grow weak but not die
C.skin becomes wrinkled with age D.every part of body ages with age
3.What might play the most important role in the graying process?
A.Genetics and the amount of sleeping time.
B.The amount of food people eat and living environment.
C.The amount of pigment and genetics.
D.Genetics and the amount of water people drink
4.From the passage we can infer that________.
A.stress causing gray hair is still in question
B.gray hair has nothing to do with tension
C.stressful situations can be of benefit
D.sound evidence has been found

Many people believe the glare from snow causes snow-blindness. Yet, dark glasses or not , they find themselves suffering from headaches and watering eyes, and even snow-blindness, when exposed to several hours of “snow light”. The United States Army has now determined that glare from snow does not cause snow-blindness in troops in a snow-covered country. Rather, a man's eyes frequently find nothing to focus on in a broad expanse of barren (少植被的) snow-covered terrain (地形). So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscles ache. Nature eases this irritation by producing more fluid which covers the eyeball. The fluid covers the eyeball in increasing quantity until vision blurs (模糊), then is obscured (遮蔽), and the result is total, even though temporary, snow-blindness.
Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark colored objects ahead on which they too can focus. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop scouring the snow-blanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snow-blind or lost. In this way the problem of crossing a solid white terrain is overcome.
1.To prevent headaches, watering eyes and blindness caused by the glare from snow, dark
glasses are _________.
A. indispensable and essential B. useful C. ineffective D. available
2.When the eyes are sore tears are produced to _________.
A. balance the pain B. treat snow-blindness
C. clear the vision D. loosen the muscles
3.Snow-blindness may be avoided by _________.
A. concentrating on the solid white terrain
B. searching for something to look at in snow-covered terrain
C. providing the eyes with something to focus on
D. covering the eyeballs with more fluid
4.The scouts shake snow from evergreen bushes in order to _________.
A. prevent the men behind losing their way
B. beautify the landscape of the terrain
C. warm themselves in the severe cold
D. give the men behind something to see
5.A suitable title for this passage would be _________.
A. nature's cure for snow-blindness
B. snow-blindness and how to overcome it
C. soldiers marching in the snow
D. snow vision and its effect on eyesight

Great white sharks! Just hearing that name makes many people’s hair stand on end. In reality, these big fish have more to fear from us than we do from them. For many years, people killed countless great white sharks in the waters around the United States.
But thanks to conservation (保护) efforts, great whites are making a comeback in the U.S. Two recent studies show that the population of these sharks is rising along the east and west coast.
Why is the growing population of a killer fish something to celebrate? “When you fish too many of them, you start to lose balance in the environment,” says shark researcher Tobey Curtis. As the biggest killer, sharks help keep the populations of fish, seals, and other creatures they eat from growing too large.
In spite of their importance, great white sharks had long been hunted for their meat and their fins (鳍). Then, in 1997, the U.S. government passed a law that didn’t allow the hunting of great whites. Afterwards, the numbers of these sharks in the U.S. waters started to increase.
The law wasn’t the only thing that has helped great whites. Conservationists have also played a part in the sharks’ comeback. The research group OCEARCH is using a method called tagging (加标签) to help change people’s attitudes about great white. They let the public follow each shark as it travels the world’s oceans. OCEARCH also gives each tagged shark a name to help people form a closer connection with the big fish.
The group’s most well-known shark is named Katharine. She was tagged last year near Cape Cod, Massachusetts. Since then, thousands of people have tracked Katharine’s movements on Twitter and the OCEARCH website.
This helps people see sharks in a new way. Chris Fischer, the founder of OCEARCH believes learning to appreciate great whites will encourage people to do more to protect them.
1.The underlined part “makes many people’s hair stand on end” in Paragraph 1 can best be replaced by______.
A. worries many people B. bores many people
C. frightens many people D. interests many people
2.The law passed in 1997 ______.
A. seemed very helpful
B. let scientists down
C. needed to be changed
D. made people like great whites
3.Katharine’s example is used to show that ______.
A. great whites are in fact lovely animals
B. the OCEARCH website has a lot of visitors
C. the number of great whites is growing quickly
D. OCEARCH help people get closer to great whites
4.The main purpose of the passage is to ______.
A. introduce an experiment result
B. make an advertisement for OCEARCH
C. remind us that big killers are dying out
D. inform us that great whites are making a comeback
