It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.

Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.

Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood back to the monkeys’ brains. When the brain’s temperature was 10℃, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.

1. The biggest difficulty in operating on the damaged brain is that        .

    A. the time is too short for doctors                          B. the patients are often too nervous

    C. the damage is extremely hard to fix                        D. the blood-cooling machine might break down

2.The brain operation was made possible mainly by        .

A. taking the blood out of the brain  B. trying the operation on monkeys first

C. having the blood go through a machine                  D. lowering the brain’s temperature

3. With Dr. White’s new idea, the operation on the damaged brain        .

A. can last as long as 30 minutes     B. can keep the brain’s blood warm

C. can keep the patient’s brain healthy                  D. can help monkeys do different jobs

4. What is the right order of the steps in the operations?

a. send the cooled back to the brain  b. stop the blood to the brain

c. have the blood cooled down         d. operate on the brain

A. a, b, c, d     B. c, a, b, d       C. c, b, d, a       D. b, c, d, a

5.Which of the following is not true?

A. If there isn’t enough blood, the brain can live for only three to five minutes.

B. If the brain is very cold, it can live without blood for half an hour.

C. Dr. White tried his idea for thirteen times.

D. After their operations, the monkeys were healthy and busy again.

I live in a very old town which is surrounding by beautiful woods. It is a famous beauty spot. In Sundays, hundreds of people come from the city to see our town and to walk through the woods. Visitors have asked to keep the woods clean and tidy. Litter baskets have been placed under the trees, and people still throw their rubbish everywhere. Last Wednesday, I go for a walk in the woods. That I saw made me very sad. I counted seven old cars and three old refrigerators. The  litter basket were empty and the ground was covered with pieces of paper, cigarette ends, old tyres, empty bottles or rusty tins. Among the rubbish, I found a sign which was said, “Anyone who leave litter in these woods will be punished!”

Chinese tradition says a different animal represents each new year of the 12-year Chinese Zodiac(黄道十二宫) cycle. According to the Chinese calendar, the year you were born may determine your personality. Every year of this cycle is represented by an animal, and legend has it that people born under that animal have certain personality traits. Here are some of them:

Dragon

The Real Thing: The mythical dragon is a symbol of power and good fortune in Chinese culture. One of the most popular figures in Chinese art, the dragon is believed to be a combination of nine animals, including a frog, a tiger, an eagle, and a fish.

Born a Dragon: You go out of your way to help your friends, who often seek you out for advice. Your outgoing personality helps you get along with many types of people.

Snake

The Real Thing: Snakes have great instincts. Some “play dead” to fool predators(捕食者), and most sense prey by detecting ground vibration(震动). They can take more than an hour to swallow a meal, and they become inactive for up to two weeks before they shed their skin.

Born a Snake: You rely on yourself before asking others their opinions. At times you want to take a break from the action. It’s not that you are lazy---sometimes you just like to think.

Pig

The Real Thing: Domesticated(驯养)pigs have been helping human for about 9,000 years. Incredibly intelligent, a pig shows its smarts by rolling in mud and sticking its snout in dirt. Why? The mud keeps it cool, and rooting in the dirt provides important vitamins.

Born a Pig: Smart and caring, you live to help other people. You have great taste and love to wallow in the nicer things in life.

Rat

The Real Thing: Most rats are highly adaptable. They can live just about anywhere and eat about anything. Before brown rats leave their underground burrows, these clever creatures send one rat ahead to make sure danger doesn’t exist outside.

Born a Rat: You welcome challenges and enjoy learning about new things. Funny and smart, you are generous and will protect your pack of friends. 

 ______

The Real Thing: The largest of the big cats, they hunt alone. They secretly move towards prey, then leap and attack when the time seems right. Dinner still escapes most of the time.

Born a _____: You are a natural leader but often like to do things by yourself. (That’s how you stay in charge!) You believe in fighting for what’s right, even if you’ll lose in the end.

1. According to the description of the last animal, we can choose _____ to fill in the blanks. 

    A. Tiger                B. Lion             C. Ox               D. Monkey

2.  The underlined word “snout” probably means _____.

A. back              B. nose                C. head                 D. tail
