Even though it has been a long time since you played the violin, a new study shows that as little as one year of music training can have a positive impact (影响) on your brain that will last the rest of your life.
In an experiment, researchers compared children who had taken music lessons to those who hadn’t. Laurel Trainor, who studies music and the mind, discovered that the musically-trained children had better brain responses in certain sound recognition exams. Trainor’s findings show the possibility that musical education can actually improve the brain’s hearing cortex(大脑皮层). “The study’s results show that music training affects attention and memory, and helps children develop learning skills. In this way music training might lead to better learning across a number of fields,” Trainor said in a statement. The effects of music education are even more obvious on children with difficulty in reading and writing and other language-related disabilities.
So, whether you can play a good piece of music or not, it’s likely that your years of music lessons have prepared your brain for all the speeches, emails, and adult conversations that are part of your life today. We should help make sure that children today have the same opportunities for music, and help out by volunteering with or donating instruments to your school’s music education department.
小题1:Compared with children who haven’t taken music lessons, musically-trained children _______.
| A．sing better | B．do better in exams |
| C．recognize sounds better | D．response more quickly |
| A．change the structure of the brain |

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.
小题1: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 |
| A．landing | B．relation | C．connection | D．behaviour |
| 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. |
| 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 |
| 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 |

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.
● Never respond to messages or bulletin board items that are: Suggestive / Obscene / Belligerent / Threatening / Make You Feel Uncomfortable.
● Be careful when someone offers you something for nothing, such as gifts and money. Be very careful about any offers that involve your coming to a meeting or having someone visit your house.
● Tell your parents or guardian right away if you come across any information that makes you feel uncomfortable.
● Never arrange a face-to-face meeting without telling your parents or guardian. If your parents or guardian agree to the meeting, make sure that you meet in a public place and have a parent or guardian with you.
● Remember that people online may not be who they seem. Because you can’t see or even hear the person, it would be easy for someone to misrepresent him or herself. Thus, someone indicating that“she”is a“12-year-old-girl”could in reality be an older man.
● Be sure that you are dealing with someone that you and your parents know and trust before giving out any personal information about yourself via E-mail.
● Get to know your“online friends”just as you get to know all of your other friends.

To prevent these difficulties, a dam may be built across the river. This will store water for dry seasons, and in wet seasons it will prevent the flooding of the land. A great lake will, no doubt, be formed behind the dam, and this may mean that houses and fields will be covered with water. Most people will accept that and will be ready to move to other places. Then the country can have the right amount of water at all times; more crops will be grown, there will be more food for everyone, and there will be no more floods.
Dams have been built for centuries in different parts of the world. Modern dame are usually built of concrete（混凝土）but earth dams were used in India and Sri Lanka about 2500 years ago. There was another across the River Tigris very long ago, and large numbers of irrigation canals were made in Iraq to irrigate the land. The Romans were great dam-builders and there was also a famous dam at Ma’ rubin Arabia.
We cannot use sea water for irrigation; the salt will not allow the crops to grow. Fresh water is always needed, and it is very difficult and costly to make fresh water from sea water. This is done in a few countries, but the fresh water is for drinking. There is not enough at present for irrigation. Perhaps a scientist will one day invent a cheaper way of producing fresh water from the sea.

| A．a dam will be built across the river |
| B．a dam will store water for dry seasons |
| C．in wet seasons a dam will prevent the flooding of the land |
| D．houses and fields will be covered will water |
| A．modern dams are made of concrete |
