Here is an astonishing and significant fact: Mental work alone can’t make us tire. It sounds absurd. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins(毒素)and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?
Some scientists declare that most of our fatigue comes from our mental and emotional attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting workers in good health is due to emotional problems.”
What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.What surprised the scientists a few years ago?
| A．Fatiguetoxinscouldhardlybefoundinalaborer’sblood. |

Hurricanes
Hurricanes are gigantic tropical storms that can be hundreds of kilometers wide. They bring along very strong winds and a lot of rainfall. They often cause flooding near the coasts and sea levels rise.
1. __________________________
Hurricanes are born over tropical oceans, usually during late summer and early autumn. They need two things to get them started: heat and moist air. During the summer the ocean surface heats up and warm moist air starts to rise. Cool air sinks down to replace it. This creates an area of low pressure. The rotation of the earth creates winds around the center of such a low-pressure area. In the northern hemisphere the air moves counter clockwise, in the southern part clockwise. Such a system is called a cyclone. When warm air rises, it cools and creates clouds. Soon, thunderstorms form and it starts to rain.
All hurricanes begin as cyclones but not all cyclones become storms or hurricanes. Some die out a few days after they start. They don’t have enough energy to become a hurricane. When winds are stronger than 119 km an hour a storm officially becomes a hurricane.
2. __________________________
The center of a hurricane is called the eye, a calm area with little rainfall. It is about 30 to 50 km wide. Inside the eye the sea can rise up to one meter because the air moves up. The eye wall is around the eye. This is an area of thunderstorms, rain and the strongest winds—up to 300 km an hour. Then come long bands of rain clouds that are curved towards the center of the hurricane.
3. __________________________
In the northern hemisphere hurricanes normally move in a westward direction and then they turn north and northeast. Their path takes them away from the warm tropical water of the equator. When hurricanes move over colder water or over land they lose a lot of their energy. They slow down and as time goes on, they disappear. In the southern hemisphere their path leads them to the south and southeast.
4. __________________________
When a tropical storm forms over the Caribbean Sea it gets a name. Every year the first storm of the season is given a name that starts with the letter A, the second storm gets a name starting with B and so on. Years ago only women’ s names were used for tropical storms. Today male and female names alternate –for example, the first storm is named Alexandra, the second one Billy, then Catherine etc. Each year new names are used so that you can connect a storm to a certain year.
5. __________________________
Hurricanes are causing more and more damage throughout the Gulf Region, mainly because the population is constantly growing. Many things can be done to protect yourself and your property during a hurricane: Keep emergency supplies of food and water; keep a battery-powered radio ready in case the power goes out. Listen to the instructions you get; keep the gas tank of your car full, in case you have to leave quickly; protect your house by nailing plywood over the windows and doors. Tie down loose objects; find out which roads are best to take you away from the storm; leave your house as soon as you are ordered to evacuate, etc.
One day Marilla said, “Anne, your new teacher, Miss Stacy, spoke to me yesterday. She says you must study for the examinations for Queen’s College in two years’ time. Then if you do well, you can study at Queen’s in Charlottetown for a year, and after that you’ll be a teacher!”
“That doesn’t matter, Anne. When Matthew and I adopted you three years ago, we decided to look after you as well as we could. Of course we’ll pay for you to study.”So in the afternoons Anne and some of her friends stayed late at school, and Miss Stacy helped them with the special examination work. Diana didn’t want to go to Queen’s, so she went home early, but Gilbert stayed. He and Anne still never spoke and everybody knew that they were enemies, because they both wanted to be first in the examination. Secretly, Anne was sorry that she and Gilbert weren’t friends, but it was too late now.
For two years, Anne studied hard at school. She enjoyed learning, and Miss Stacy was pleased with her. But she didn’t study all the time. In the evenings and at weekends she visited her friends, or walked through the fields with Diana, or sat talking to Matthew.
“Your Anne is a big girl now. She’s taller than you,” Rachel Lynde told Marilla one day.
“You’re right, Rachel!” said Marilla in surprise.
“And she’s a very good girl now, isn’t she? She doesn’t get into trouble these days. I’m sure she helps you a lot with the housework, Marilla.”
“Yes, I don’t know what I’d do without her,” said Marilla, smiling.
“And look at her! Those beautiful grey eyes, and that red-brown hair! You know, Marilla, I thought you and Matthew made a mistake when you adopted her. But now I see I was wrong. You’ve looked after her very well.”
“Well, thank you, Rachel,” replied Marilla, pleased.
That evening, when Matthew came into the kitchen, he saw that his sister was crying.
“What’s the matter?” he asked, surprised. “You haven’t cried since… well, I can’t remember when.”
“It’s just… well, I was thinking about Anne,” said Marilla. “I’ll…I’ll miss her when she goes away.”
“When she goes to Queen’s, you mean? Yes, but she can come home at weekends, on the train.”
“I’ll still miss her,” said Marilla sadly.”
In June the Avonlea boys and girls had to go to Charlottetown to take their examinations.
“Oh, I do hope that I’ve done well,” Anne told Diana when she arrived back at Green Gables. “The examinations were very difficult. And I’ve got to wait for three weeks before I know! Three weeks! I’ll die!”
Anne wanted to do better than Gilbert. But she also wanted to do well for Matthew and Marilla. That was very important to her.
Diana was the first to hear the news, she ran into the kitchen at Green Gables and shouted, “Look, Anne! It’s in Father’s newspaper! You’re first… with Gilbert… out of all the students on the island! Oh, how wonderful!” Anne took the paper with shaking hands, and saw her name, at the top of the list of two hundred. She could not speak.
“Well, now, I knew it,” said Matthew with a warm smile.
“You’ve done well, I must say, Anne,” said Marilla, who was secretly very pleased.

“China is expected to complete its first exploration (探索) of the moon in 2010 and will found a moon base just as we did on the North and South Poles,” Ouyang Ziyuan, head of China's moon exploration program, promised during national science and technology week.
After its first man in space, China plans a space laboratory, a lunar orbiter to look for valuable elements and minerals, robot landings on the moon and then the human touchdown.
The price of space exploration is enormous. Russia and the US, the only two countries to have achieved manned flight, are struggling to keep their new investment, the international space station.
But China, which has a long tradition in physics, mathematics and engineering, finds its doctoral graduates welcomed in the US and Europe for decades. And it has been able to learn from 40 years of pioneering successes and mistakes by the USSR and the USA.
Space flight is a gamble and the stakes (赌注) are high. If successful, China could become a member of the world's most exclusive club, set up a second home on the moon and get a powerful hand at the strategic bargaining table.
Two designers from the Shenzhou III project said that 12 astronauts now are undergoing intensive training. One more unmanned space flight is planned before the first manned launch.
Experts say that the Shenzhou spacecraft already provides China with a space vehicle capable of mounting（发起）a lunar program. Chinese scientists have also predicted that Mars will be the next target after the moon.According to Ouyang Ziyuan ________.
| A．China has founded a base on the moon |
| B．China has founded one base on the North and South Poles |
| C．China will set up a base on the moon in 2010 |
| D．China has already finished founding a moon base |
The underlined word “touchdown” in the second paragraph means “________”.
| A．landing | B．relation | C．connection | D．behaviour |
Which one of the following is NOT right according to this passage?
| A．A second home is going to be built on the moon in 2010. |
| B．China's first man has landed the moon in space. |
| C．People from only two countries have been to the moon till now. |
| D．Twelve Chinese astronauts are being trained for the manned flight to the moon. |
We think that the Chinese astronaut will succeed in landing the moon in 2010 because ________.
| A．China will ask for help from the USSR and the USA |
| B．two countries have set up a space station on the moon |
| C．China has a large population in the world |
| D．China has its tradition technology and advanced scientists |
We can infer from this passage that.
| A．China’s robot landing in the moon has been successful |
| B．the USSR and the USA don’t allow Chinese people to land on the moon |
| C．Chinese scientists show great interest in exploring Mars now |
| D．it is impossible for the Chinese people to land on the moon |
