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 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 replaced，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

3.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．

4.What might play the most important role in the graying process?

A．Genetics and the amount of sleeping time

高二英语单项填空中等难度题查看答案及解析

We all know what it is like to be unable to turn your head because of a cold in the muscles of your neck, or because an unexpected twist has made your neck ache and stiff. Your whole body feels tight. The slightest move makes you jump with pain. Nothing could be worse than a pain in the neck. That is why we use phrase to describe some people who give you the same feeling. We have all met such people.

One is the man who always seems to be clapping his hands—often at the wrong time—during a performance in the theater. He keeps you from hearing the actors.

Even worse are those who can never arrive before the curtain goes up and play begins. They come hurrying down to your row of seats. You are comfortably settled down, with your hat and heavy coat in your lap. You must stand up to let them pass. You are proud of your self-control after they have settled into their seats…Well, what now…Good God, one of them is up again. He forgot to go to the men’s room, and once more you have to stand up, hanging on to your hat and coat to let him pass. Now, that is “a pain in the neck.”

Another, well-known to us all, is the person sitting behind you in the movies. His mouth is full of popcorn; he is chewing loudly, or talking between bites to friends next to him. None of them remain still. Up and down, back and forth, they go for another bag of popcorn, or something to drink.

Then, there is the main sitting next to you at a lunch counter smoking a smelly cigar. He wants you to enjoy it too, and blows smoke across your food into your mouth.

We must not forget the man who comes into a bus or subway car and sits down next to you, just as close as you will let him. You are reading the newspaper and he leans over and stretches his neck so that he can read the paper with you. He may even turn the paper to the next page before you are ready for it.

We also call such a person a “rubberneck”, always putting out his neck to where it does not belong, like neighbors who watch all your visitors. They enjoy invading your privacy. People have a strong dislike for rubbernecks. They hate being spied upon.

1.Where can you find this passage?

A. Medicine dictionaries.  B. A travel guide.

C. Social science books.     D. Students text books.

2.How do you feel when late comers walk back and forth in front of you in a cinema?

A. Disturbed.     B. Ignored.         C. Bored.  D. Relaxed.

3.A “rubberneck” often ________.

A. says bad words behind people

B. quarrels face to face with neighbors

C. bargains the price with sales women

D. asks about other people’s business

4.Which of the follow is “a pain in the neck”?

A. Someone who helps you find your seat in a movie theatre.

B. Someone who smokes in a smoking section on a train.

C. Someone who throws trash out of his car window on the highway.

D. Someone who goes to the doctor for his severe pain on the neck.

How to Strengthen Your Willpower

Researchers find willpower is like a muscle—it may get tired from over use. So, if it acts like a muscle, can it also be strengthened? The answer is YES. 1.

1. Ten minutes of reflection

Reflection will give you the fater results. 2. Researchers show that after just 2—3 days of practicing thinking for 10 minutes, your brain will be able to focus better, you will have more energy, and you aill be less stressed.

2. Work on your posture

Work on your posture for a 2-week period. Every time you catch yourself slouching(懒散), correct it by sitting up straight. This simple practice can vastly improve your perseverance.

3. Use your opposite hand

Select a chunk(块) of the day to use your opposite hand. 3. And from personal experience, if you aim for more than an hour, you will unnecessarily tire out your willpower muscle.

4. Correct your speech

Change your natural speech. 4. Again, it takes willpower to consciously go against your instincts. It doesn’t matter how you correct your speech, as long as you change natural speech habits.

To get started, select a chunk of the day to practice and choose the words you will change. Personally, I tried not using contractions during work hours and it worked very well.

Above are some effective ways to strengthen your perseverance. Do not try to do all at once. 5. You should start small and gradually build up as your muscles get stronger.

A. Training your willpower muscle is like training for a marathon.

B. This even includes resisting the urge to say “hello” instead of “hey”.

C. You will be more mentally strong.

D. With the right practice willpower can be strengthened.

E. It can make your brain focus and resist the urge to wander.

F. Be more conscious of your automic decisions.

G. It doesn’t need to be more than an hour in order to get results.

高二英语七选五中等难度题查看答案及解析

You finish a workout and feel great. Then you get up the next morning and your exercised muscles feel sore. You find it hard to lift your arms and brush your teeth, or bend down to pick up a book. What has happened?

Scientists call this soreness 24 to 48 hours after your exercise “delayed onset (延迟发作) of muscle soreness”, or DOMS. It is caused by microscopic damage to muscle fibers, which releases chemicals. The chemicals irritate (刺激) nerve fibers and cause pain.

Muscle soreness is a good sign. It means that you have challenged your muscles and are getting stronger. Everyone experiences it, even the best athletes. But it can be avoided by using the right exercise methods. Here are some tips:

* Warm up before you work out. This is helpful to avoid muscle soreness, but more importantly to avoid injury. It starts circulation to the muscles and warms the muscles and tendons, getting them ready for exercise.

* Stretch after your workout. After exercising, make sure you stretch your muscles for 15 to 20 seconds before they cool down. They will be warm and elastic (弹性的) so they will stretch well.

* Don’t do too much too soon. Whether it’s jogging, running, whatever workout routine you are starting, just do half of the exercise volume the first week to introduce your muscles to the exercises.

If you are already feeling muscles soreness, here are some ways to help relieve it.

* Get a massage (按摩). Lightly massage the sore muscle and gradually increase the depth of the massage. It might be painful in the beginning but it will gradually ease the muscle soreness.

* Take a hot bath. Nothing beats a long soak in a hot bath for muscle soreness. The heat will increase circulation and provide a soothing (舒缓) effect.

* Flush your muscles. Run hot (as hot as you can bear) water over the sore muscles for two minutes and then immediately switch to cold water for 30 seconds. Repeat this process five times. This has the effect of opening and closing your blood vessels (血管). It will flush the acid (酸物质) from them and ease the soreness.

* Exercise gently. Go for a slow walk and breathe deeply. This helps reduce muscle soreness by increasing blood flow to the sore muscles.

72. What is the purpose of this article?

A. To tell readers to exercise more for fitness.

B. To warn readers of the side effects of exercise.

C. To give readers advice on how to avoid and relieve muscle soreness.

D. To introduce good forms of exercise.

A. stretch our muscles                   B. have a massage

C. have a hot shower                   D. warm up our muscles

74. From this article we can conclude that muscle soreness is caused by ______.

A. damaged muscle fibers               B. damaged nerve fibers

C. a bad circulation to the muscles        D. exercise injuries

75. Judging from the article, which of the following statements is TRUE?

A. Only beginners get muscle soreness.

B. Muscle soreness means you have physical problems and should stop exercising.

C. Muscle soreness is a good sign because it means that the muscles are getting stronger.
