Sandstorms hit northwestern China's Gansu Province and North China's Inner Mongolia Autonomous Region on the first day this year. According to Sun Landong， a meteorologist with the Lanzhou Meteorology Observatory，visibility was less than 100 meters in Minqin， a Gansu county near Inner Mongolia， because of sand. When visibility drops to less than 1 
kilometer，it is called a sandstorm. The sandstorm in Minqin blew up dust in neighboring towns， such as Baiyin， Wuwei， Jinchang and Lanzhou， the capital city of Gansu Province. Dust-laden winds also
swept into Beijing. Brought by northwesterly blowing at more than 20 meters per second，dust first reached the capital's suburbs at 7 a. m，downtown areas at 9 a. m. The winds，which died down during the night，brought the temperature down to as low as 80C below zero and many flights put off their planned time from the city's airport.
It is quite rare for sandstorms，which are frequent between March and June，to happen in winter，when the earth is frozen. The sandstorms in Gansu and Inner Mongolia do not necessarily mean there will be more of them in the spring than last year，when they were serious，but Beijing is taking it very seriously. It is reported that Beijing will spend 6 billion yuan ( US 725 million) in preventing sandstorms in the capital and has already set up a special team to make sure what causes them. What is the main idea of the passage?
| A．Sandstorms took place in Gansu. |
| B．Sandstorms happened on the first day of the new year. |
| C．Sandstorms are very serious，compared to last year. |
| D．Experts are trying their best to determine the cause of the sandstorm formed this year. |
Suppose the dust was 300 kilometers away from Beijing， it would reach Beijing about
hours later if it travels at a speed of 20 meters per second?
| A．4. 2 | B．1. 5 | C．2. 0 | D．2. 5 |
Why did sandstorms begin in the winter this year?
| A．Because there was little snow this season. |
| B．Because a lot of trees have been cut down. |
| C．Because people took few measures to control them. |
| D．It is not mentioned in the passage. |

ne in Beijing?

The tree blocked the view and made the office seem dull. Unfortunately, this happened to be the room assigned(分配)to me, and l was depressed by it for quite some time.
When the first spring came, everything was green except the locust tree.I felt very happy because I had thought it had died!

Some people can stay up all night and still get work done the next day. I’m not one of them. After a night without enough sleep, I feel sleepy. I have trouble remembering things. And all I want to do is to go back to bed and sleep.
How do you feel after you’ve stayed up late to finish schoolwork? Or the day after a slumber(睡眠) party? Scientists now say that your answers to these questions may depend on your genes, which tell our bodies and brains what to do. People have about 40,000 genes, and each gene can have different forms.
A new research suggests that a gene called period3 affects how well you function without sleep. The discovery adds to older evidence that period3 helps determine whether you like to stay up late or get up early.
The period3 gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you.
Scientists studied 24 people who had to stay awake for 40 hours straight. Then they took tests that measured how well they could remember lists of numbers.
Results showed that the people with the short form of period3 performed much better than those with the long form did. In both groups, people performed worst in the early morning. After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests took about 18 minutes to nod off(瞌睡).
People with long period3 gene fell asleep in just 8 minutes. They also spent more time on deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form.
I think I must have the long form period3. What about you?

Are you carrying too much on your back to school? Lots of kids of your age are. Not only are students in China suffering from the problem, but kids in the United States are puzzled by heavy school bags.
Experts are starting to worry that young students are having back and neck problems as a result of school bags being too heavy for them. It is hard for me to get up the stairs with my bag because it's so heavy, said Rick Hammond, an 11-year-old student in the US.
Rick is among the students who have regular backpacks(背包) with two straps (带子) to carry them, but a number of other students choose rolling backpacks. But even with rolling backpacks, getting up stairs and buses with them is still a problem for kids. Many of them have hurt their knees, backs or necks because of heavy school bags.
But how much is too much? Experts say students should carry no more than 10 to 15 percent of their own body weight. Scott Bautch, a Wisconsin back doctor, said kids under 4th grade should stay with 10 percent, but it’s also important that older kids don’t go beyond (超出) 15 percent, because their bones are still growing.
Bautch explained that there are other injuries caused by backpacks. Kids are losing their balance and falling down with these backpacks, he said.
Parents and teachers are starting to tell kids to only take home library books they will be reading in the evening. Some teachers are using worksheets (作业单 ) or thin workbooks for students to take home.
One of the best answers is, as some kids suggest, to have no homework at all!
60. According to experts, a primary student in Grade 6, who is 4
0 kilograms, should carry a bag weighing ______ kilograms at most.
A. 4 B.6 C.8 D.10
61. As school bags are too heavy for younger students to carry, they ______.
A. show no interest in studying at s
chool.
B. often fall ill
C. are having back and neck problems
D. usually ask their parents for help
62. The author wrote the passage to _____.
A. seek(寻找) ways to solve the problem of heavy bags
B. appeal (呼吁) to teachers for caring for the students
C. criticize(批评) the government for having done nothing to help students
D. tell us that heavy bags are bad for students’ health
63. Parents and teachers are starting to tell kids to take home only library books they will be reading in the evening to ______.
A. make students more interested in reading than watching TV
B. give them more free time to play

At Harton College—an English boarding school for boys —there are many rules. 15-year-old Bob Sanders often breaks them.
The boys can go into the town in the afternoon after class. But they must return to the school at six o’clock. One afternoon Bob walked to the town. He looked at the shops and then went to the cinema. After the film, he looked at his watch. It was after eight o’clock. He was a little worried. He walked back to Harton College as fast as possible.
When he arrived, he ran quickly to the main entrance. It was locked. He went round the school building to another door, which was locked too. He looked up at the window of his dormitory on the third floor. The window was open. But it was quite dark, and he could not climb up the wall easily. Then he saw another open window on the ground floor. It was the window of the headmaster’s study.
He looked into the room—no one was there. Bob quickly climbed on to the window sill（窗台）and jumped into the room. Just then he heard a noise. Then someone turned on a light in the corridor（走廊）. Bob looked around and then hid under the sofa. One minute later, Mr. Mannering, the headmaster, came in. He turned on the light on his desk, and sat down on the sofa.

“Why doesn’t he get up and go to bed ?” Bob thought.
Mr. Mannering read his book for another hour. Finally, the headmaster closed his book and stood up. He put the book on a shelf and walked towards the door.
