How would you like to brush a crocodile’s teeth? Or give a shark a bath? Cats are well-known for the way they keep themselves clean by licking （舔）, but other animals have their own ways to stay clean as well. And tidiness can be important for their survival. Even cockroaches （蟑螂） have to keep their feelers clean to help them into food.

Many animals in the wild, such as deer, wolves and bears, have an automatic cleaning system. Insects like to attach themselves to animals to feed on the skin or blood. These parasites （寄生虫） can be unhealthy. But their “host” animals are constantly dropping skin and fur by a natural process. They also like to rub up against trees or rocks to comfort themselves, and this removes additional skin and fur. Along with old fur goes the dirt and parasites living in the fur. While these animals may sometimes take a bath when they enter or cross a river or lake, they don’t need the water to stay clean. They don’t get sweaty, because they don’t have sweat glands （汗腺） all over their bodies the way people do. Growing new skin and fur is enough to keep them clean.

Some animals and birds use dust to get clean. Chinchillas, a kind of small animal that lives in the mountains of South America, have a very fine fur. （They are raised for their fur, in fact.） If they took water baths, they might get too cold. So, instead, they roll around in fine dust, raising quite a cloud as they “bathe”. The dust helps to keep their fur and skin dry. This protects them from bacteria and parasites that enjoy warm and wet places. And the fine dust doesn’t stick in their fur for long. It falls off or blows away.

As for lions and tigers, their rough tongues act like combs and can remove dirt and loose fur. Why is it important for them to stay clean and smooth? It helps them stay cool in very hot summer or feel warm in cold winter.

64. What’s the main idea of this passage?

A. Animals enjoy living in a clean environment.

B. Animals fight against parasites in different ways.

C. Unlike people, animals hate staying in water.

66. It can be inferred from the passage that the way some animals stay clean        .

A. is decided by their physical conditions

B. is better than the way people do

October 15^th 2008 is the first Global Handwashing Day, whose goal is to create a culture of hand washing with soap. Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap.

150,000 bars of soap were given to schools in Ethiopia, where the Education Ministry asked 1,000,000 schoolchildren to wash their hands for the event. 

Experts say people around the world wash their hands but very few use soap at critical moments such as after using the toilet, after cleaning a baby and before touching food.

The organizers say all soaps are equally effective at removing disease-causing germs(细菌). They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Rub for at least 20 seconds.

Then, wash your hands well under running water. Finally, dry your hands with a clean cloth or wave them in the air.

They say soap is important because it increases the time that people spend washing. Soap also helps to break up the grease(油脂) and dirt that hold most of the germs. And it usually leaves a pleasant smell, which encourages people to wash again.

They say washing with soap before eating and after using the toilet could save more lives than any vaccine or medicine. It could help reduce cases of diarrhea(腹泻) by almost half. And it could reduce deaths from pneumonia(肺炎) and other breathing infections by one-fourth.

Diarrhea is the second leading cause of child deaths, killing more than 1,500,000 children a year. Pneumonia is the leading cause, killing about 2,000,000 children under five each year. Hand washing can also prevent the spread of other diseases.

When people get germs on their hands, they can infect themselves by touching their eyes, nose or mouth. Then they can infect others.

60. What does the underlined word “the event” in Paragraph 2 refer to?

A. 150,000 bars of soap were given to students.

B. Over twenty countries organized different activities.

C. October 15^th 2008 becomes the Global Handwashing Day

D. Millions of people in the developing world wash their hands.

61. Which of the following situation doesn’t belong to a critical moment?

A. Before having dinner.

B. When cleaning a baby.

C. After using the toilet.

D. While washing the dishes

62. Why is it necessary for people to wash their hands with soap?

A. To prevent the spread of disease.

B. To remove disease-causing germs

C. To get rid of the dirt the hands hold.

D. To make their hands smell pleasant.

63. What can we learn from the text?

A. 1,500,000 children die of Pneumonia each year.

B. Soap plays an important role in removing germs.

C. Washing hands saves 1,00,000 children from Diarrhea.

D. Breathing infections cause the largest number of child death.

Burns can be caused by fire, the sun, chemicals, heated objects or fluids, and electricity. They can be minor problems or life-threatening emergencies. Distinguishing a minor burn from a more serious burn involves determining the degree of damage to the tissues of the body. If you are not sure how serious the burn is, seek emergency medical help.

    First-degree burns are those in which only the outer layer of skin is burned. The skin is usually red and some swelling (肿大) and pain may occur. Unless the burn involves large portions of the body, it can be treated at home.

    Second-degree burns are those in which the first layer of skin has been burned through and the second layer of skin is also burned. In these burns, the skin reddens intensely and blisters (水泡) develop. Severe pain and swelling also occur. Second-degree burns require medical treatment.

    Third-degree burns are the most serious and involve all layers of skin. Fat, nerves, muscles, and even bones may be affected. Areas may be charred black or appear a dry white. If nerve damage is substantial, there may be no pain at all. These burns require emergency medical attention.

    Follow these steps when treating minor burns at home:

1) If the skin is not broken, run cool water over the burn for several minutes.

2) Cover the burn with a sterile (消过毒的) bandage or clean cloth.

3) Take aspirin to relieve any swelling or pain.

    Seek emergency treatment immediately for major burns. Before an emergency unit arrives, follow these steps:

1) Remove the person from the source of the burn (fire, electrical current, etc.).

2) If the person is not breathing, begin mouth-to-mouth resuscitation (人工呼吸) immediately.

3) Remove all clothing to stop further burning. If the clothing is stuck to the burn, do not attempt to remove it.

4) Cover the burned area with a cool, moist, sterile bandage or clean cloth. Do not place any creams, ointments (药膏) or ice on the burned area or break blisters.

5) Monitor the patient for signs of shock, and treat accordingly.

The underlined sentence in the first paragraph probably means “______”.

A. They can be dangerous if you don’t treat them seriously

Ｂ. They range from slight burns to deadly ones

C. They seldom cause deaths even if not treated properly

D. They usually cause deaths if not treated properly

Burns are divided into different degrees according to _______.

A. what kind of treatment they need

B. what kind of tissue of the body is damaged

C. whether there is pain and what degree of pain there is

D. which layer of skin is burned

From the passage we learn that _______.

A. if there is severe pain, then you need medical treatment

B. first-degree burns don’t require medical treatment

C. burns without pains can be treated at home

D. the larger the swelling is, the more serious it is

 It can be inferred from the passage that ______.

A. you shouldn’t cover the burn with a bandage or cloth if it is severe

B. you shouldn’t move the person unless you know how to do first aid

C. you shouldn’t run cool water over the burn if the skin is broken

D. you shouldn’t place any wet towels on the burned area
