When I was small and my grandmother died I couldn’t understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying.　　

   So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that crying does so, too.　　

Whatever it takes for us to reduce pressure is important to our emotional (情感的) health, and crying seems to be helpful. Study found that 85 percent of women and 73 percent of men report feeling better after crying.　　

Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and more friendly and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don’t even know we’re very sad until we cry. We learn about our emotions through crying, and then we can deal with them.　　

Just as crying can be healthy, not crying — holding back tears of anger, pain or suffering — can be bad for physical health. Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don’t fight it. It’s a natural — and healthy — emotional response (反应).

Plastic is everywhere because plastic is an extremely useful material. It is cheap, strong and lightweight. What’s more, it can take on nearly any form or shape, from soft and stretchy (有弹性的) to hard and glasslike.

Plastic, however, is far from perfect. It may even be bad for us. Studies now suggest that poisonous chemicals can get out of some types of plastic, get into our bodies, and cause a variety of health problems, including cancer, birth defects and attention deficit hyperactivity disorder (注意缺陷障碍).

Two types of chemicals in particular have raised special concern lately. They are called phthalates (邻苯二甲酸盐) and Bisphenol-A (二酚基丙烷), BPA for short. Not all plastic products contain them. But the ones that do are surrounded by controversy (争议). That’s because experts disagree on how dangerous these chemicals are.

Plastic is a single word, but plastic isn’t just one thing. What all plastics share in common are plasticizers -- special chemicals that allow the material to be changed into nearly any shape or texture. Plasticizers (塑化剂) are added to plastic during the manufacturing process.

Phthalates and BPA are two types of plasticizers that work in different ways. Phthalates add softness to things like shampoo bottles, raincoats and rubber. They are also used in perfumes and makeup. BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles. BPA also appears in food and soda cans, DVDs and other unexpected places.

How do these chemicals get into us? When plastic is heated in the microwave or dishwasher, chewed on or scratched, the chemicals can seep (渗透) out of the plastic. Even though we can’t see them, we eat them, drink them and breathe them in.

Scientists and parents are especially worried about young children, who tend to chew on everything, including plastic. Dozens of countries, including the European Union, Japan, Canada and Mexico have already banned phthalates from products made for children younger than three. California and Washington have done the same. And a number of other states are considering similar rules. As for BPA, Canada became the first country to ban the chemical from baby bottles. A dozen states are considering it.

1.What can we know about the plastic from the first paragraph?

A. Its characters and effects.                   B. Its wide use and bad points.

C. Its importance and chemicals.               D. Its popularity and advantages.

2.Which of the following products contains BPA?

A. A soft plastic cup.                           B. A pencil eraser.

C. A baby milk bottle.                            D. A new perfume.

3.Phthalates and BPA can get into us __________.

A. through mouth or nose                          B. through blood transfusion

C. by feeling plastic products                  D. by heating in the microwave

4. What is the passage mainly about?

A. A new ban on plastic products.             B. Problems caused by the plastic. 

C. Good points of the plastic.            D. The use of plasticizers.

As is known to us all, baths and bathing have long been considered of medical importance to man. In Greece there are the ruins of a water system for baths built over 3,000 years ago. The Romans had warm public baths. In some baths, as many 3,000 persons could bathe at the same time.
Treating disease by taking bathing has been popular for centuries. Modern medical bathing first became popular in Europe and by the late 1700’s has also become popular in the United States.
For many years frequent(经常的) bathing was believed to be bad for one’s health. Ordinary bathing just to keep clean was avoided, and perfume was often used to cover up body smells!
By the 1700’s doctors began to say that soap and water were good for health. They believed that it was good for people to be clean. Slowly, people began to bathe more frequently. During the Victorian Age of the late 19th century, taking a bath on Saturday night became common.
In the United States ordinary bathing was slow to become popular. During the 18th and early 19th centuries, many Americans were known as “The Great Unwashed!” In one American city, for example, a person was only allowed to take a bathe every thirty days! That was a law!
Frequency of bathing today is partly a matter of habit. People know that bathing for cleanliness is important to health, Doctors know that dirty bodies increase the chance of diseases. As a result, in the United States, people generally bathe often. Some people bath once a day at least. They consider a daily bath essential (="necessary)" to good health.
