Stress is one of the most common causes of health problems in modern life. Too much stress results in physical, emotional, and mental health problems.

There are numerous physical effects of stress. Stress can affect the heart. It can increase the pulse rate, make the heart miss beats, and can cause high blood pressure. Stress can affect the respiratory (呼吸的) system. It can lead to asthma and cause a person to breathe too fast, resulting in a loss of important carbon dioxide. Stress can affect the stomach. It can cause stomachaches and problems of digesting food. These are only a few examples of the wide range of illnesses and symptoms resulting from stress.

Emotions are also easily affected by stress. People suffering from stress often feel anxious. They may have panic attacks and feel tired all the time. When people are under stress, they often overreact to little problems. For example, a normally gentle parent under a lot of stress at work may yell at a child for dropping a glass of juice. Stress can make people angry, moody, or nervous.

Long-term stress can lead to a variety of serious mental illnesses. Depression, an extreme feeling of sadness and hopelessness, can be the result of continued and increasing stress. Alcoholism and other addictions often develop as a result of overuse of alcohol or drugs to try to relieve（释放）stress. If stress is allowed to continue, then one’s mental health is put at risk.

It is obvious that stress is a serious problem. It attacks the body. It affects the emotions. Untreated, it may eventually result in mental illness. Stress has a great influence on the health, our feelings and our minds. So, reduce stress: stop the world and rest for a while.

1.What physical effects does stress result in?

A.Overreacting to little problems.

B.Making blood pressure low.

C.Suffering from depression.

D.Increasing the pulse rate.

2.Which one belongs to the emotional problem?

C.MuchAnxiety.

D.Heartbeat missing.

3.What does the fourth paragraph mainly talk about?

A.Stress causing mental problems.

Electric cars are dirty. In fact, not only are they dirty, but they might even be more dirty than their gasoline-powered cousins.

People in California love to talk about “zero-emissions (排放) vehicles”, but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Apart from the few people who have their roofs covered with solar cells, we get our electricity from generators (发电机). Generators are fueled by something----usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal (地热) plants as well, but by far we get electricity mainly by burning something.

In other words, those “zero-emissions” cars are likely coal-burning cars. Because the coal is burned somewhere else, it looks clean. It is not true. It's as if the California Greens are covering their eyes----“If I can't see it, it's not happening.” Gasoline is an incredibly (极其) efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat--at the generator, through the transmission lines, etc.

A gallon of gas may drive your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far---so electric cars burn more fuel than gasoline-powered ones. If our electricity came mostly from wind or geothermal, or solar, then an electric car truly would be clean. But for political, technical, and economic reasons, we don't use much of those energy sources.

In addition, electric cars' batteries which are poisonous for a long time will eventually end up in a landfill (垃圾填埋场). And finally, when cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are not too concentrated, but it takes a lot longer when all the garbage is in one spot.

1.Which of the following words can replace “be clueless about” in Paragraph 2?

A. be familiar with.　　　　　　　　　　　　　 B. fail to understand.

C. be curious about.　　　　　　　　　　　　　 D. show their interest in.

2.The electricity we get from a gallon of gas may make our car run _________.

A. at least 25 miles　　　　 　　　　　　　　 B. more than 25 miles

C. less than 25 miles　　　　　　　　　　　　 D. as far as 25 miles

3.In the author’s opinion, compared with cars using gas, electric cars are more __________.

A. harmful　　　　　　　　　　　　 　　 B. expensive

C. efficient　　　　　　　　　　　　　　 D. environmentally-friendly

4.It can be inferred from the passage that __________.

A. electric cars’ batteries are no longer poisonous in the landfill

B. electric cars are not clean since we get electricity mainly by burning something

C. zero-emissions vehicles should be chosen to protect our environment

D. now electric cars are used more than their gasoline-powered cousins

If you have to miss one meal a day, which meal will cause you fewest health problems if you don’t eat it? If they have to make a decision of this type, most people (especially very busy people) will choose to skip (not to eat) breakfast.

However, many experts in the field of health consider breakfast (the meal which “breaks” your “fast---- a period of time without eating anything ” which started the night before) to be the most important meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients we need to begin our working day with vigor and hopefully with good humour. But many people skip breakfast or replace it with snacks or a cup of coffee for a well-balanced meal. What happens if we ignore the importance of breakfast?

One recent study conducted in the United States tested a large number of people. Participants included both males and females who ranged in age from 12—83. During the experiment, these people were given a variety of breakfasts, and sometimes, they had to skip breakfast completely. Special tests, including blood tests and endurance tests, were set up to analyze how well the participants’ bodies functioned when they had eaten a certain kind of breakfast.

The result showed that if a person eats an adequate (充足的) breakfast, he or she will work more efficiently and more productively than if he or she skips breakfasts or eats a very poor breakfast. This fact appears to be especially true if a person’s work involves mental activity. The study showed that if schoolchildren eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate on their lessons for a longer period of time than if their breakfast diet is inadequate .

The study also showed that, contrary to what many people believe, if you skip breakfast, you will not lose weight. This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing. So remember, if you are on a diet, skipping breakfast will not help you. You will probably lose more weight if you reduce your other meals.

1.According to the passage, we can safely say _____.

2.In the word “breakfast”, “fast” probably means _____.

3.Special tests were organized to analyze how participants’ bodies functioned when ______.
