Annealing is a way of making metal softer by heating it and then letting it cool very slowly. If metal is heated and then cooled very quickly , for example by dipping it in water , it will be very hard but also very brittle(脆)---that is , It will break easily. Metal that has been annealed is soft but does not break as easily . It is possible to make metal as hard or as soft as is wished, by annealing it. The metal is heated, and allowed to cool slowly , for a certain length of time. The longer the heated metal takes to cool slowly , the softer it becomes . Annealing can also be used on other materials, such as glass.
小題1: Annealing can make metal _______________.

A．hard and tough (韌)	B．hard but brittle
C．soft but tough	D．soft and brittle

小題2: Why do people put hot metal in water ? ____________

A．To make it hard	B．To make it soft
C．To make it cool	D．To make it brittle

小題3: As suggested by the text , how can glass be made less brittle ?____________

A．It can be heated and then cooled quickly

B．It can be cooled and then heated slowly

C．It can be heated and then cooled slowly

D．It can be cooled and then heated quickly

Recently, a student used his Personal Digital Assistant (PDA) to film a female teacher scolding and tearing the work of a classmate. The public discussion that the incident caused started on the Internet. However, when it came to the media’s attention, it quickly became a major topic in the education circles. The reactions so far suggest that the focus of the debate has been on one question: whom to blame?
Teachers who are anxious to defend their professional dignity have tried to put the blame on the students. They mentioned their right to privacy 隱私）and for this reason they requested the Ministry of Education (MOE) to prohibit PDAs in schools. On the other hand, some parents and students have taken a different position. They feel that the teacher is also at fault. Caught up in the war of words between both sides, people are no longer interested in the “truth” of the matter which seems now unimportant. It was left to newspapers to discover the central point of the controversial issue, by stressing the problems that are not always easily noticed in our educational system.
For those responsible for educating the young, this PDA incident conveys the message that “Times have changed”，a reality that must have been felt even more strongly by the female teacher when reflecting on this unpleasant experience. Different times call for different professional approaches in education. The ability to understand the students they are teaching has always been the quality of successful teachers. Despite some factors, the incident shows that the teacher lacks good qualities on her part. Besides, the rules under current system to deal with recalcitrant students need to be improved. Also, it is an example which shows the issue we are familiar with: what to do with new technology? With PDA, the new technology, the interaction (交流）between the teacher and students in classroom has been changed.

B．The PDA incident

C．Times have changed

D．What to do with new technology?

Water is very important to living things. Without water there can be no life on the earth. All animals and plants need water. Man also needs water. We need water to drink, to cook our food and to clean ourselves. Water is needed in offices, factories and schools. Water is needed everywhere.

First Lady Michelle Obama urged students to visit China at the "100,000 Strong" China Study Abroad forum at Howard University in 2011.
President Barack Obama announced the "100,000 Strong" Initiative （倡議） during his 2009 visit to China. The program aims to increase and diversify the number of American students studying in China by making studying abroad more affordable.
During the event at Howard, Mrs. Obama spoke about the importance of studying abroad, something she never did while in college. "Studying in countries like China is about so much more than just improving your own prospects（前景） in the global market. The fact is that with every friendship you make and every bond of trust you establish you are shaping an image of America projected to the rest of the world," she said.
David Marzban from Pepperdine University recalled a time when he formed a cross-cultural bond with a complete stranger at a restaurant near Fudan University in Shanghai. He noticed a young chef signaling him to come over. "He presses the play button on his media player and starts singing 'California Dreaming' and wants me to sing along with him," Marzban said. "At this time I knew a great friendship had started during my first two weeks in China."
Nicole Baden, a senior communications major at Howard University, recalled how her time in China really helped her master the language. "You have to experience the culture while learning the language to really master it and to understand why things are how they are compared to your own culture," Baden said.
Mrs. Obama encouraged students to set aside concept that studying abroad is for rich kids only or for those attending certain schools. In addition, the first lady announced that the Chinese government is giving 10,000 "Bridge Scholarships" to cover costs for American students and teachers studying in China.
Students from several schools attended the forum. 12-year-old Sarah Davis, who studied in China last summer, said she was very excited to hear Michelle Obama talk about the country. “I love Chinese. Out of all the languages I’ve learned, Chinese is the most difficult and interesting,” she said.
小題1:The examples mentioned in the passage mainly indicate that _____.

A．the US students’ life in China is helpful and worthwhile

B．a(chǎn)ll students of the US are living a comfortable life in China

C．Chinese young people are friendly to foreigners

小題2:What can we infer from the passage?

A．Baden came to China to study the differences between English and Chinese.

B．Poor children from America have no opportunity to study in China.

C．David Marzban made a Chinese friend in an unexpected way in China.

D．Michelle Obama called on US students to study in China at a government meeting.

小題3:What is the best title for the passage?

A．The US has an ambitious program for Americans studying in China.

B．Michelle Obama encourages American students to study in China.

It’s not easy being a teenager---nor is it easy being the parent of a teenager. You can make your child feel angry, hurt, or misunderstood by what you say without realizing it yourself. It is important to give your child the space he needs to grow while gently letting him know that you’ll still be there for him when he needs you.
Expect a lot from your child, just not everything. Except for health and safety problems, such as drug use or careless driving; consider everything else open to discussion. If your child is unwilling to discuss something, don’t insist he tell you what’s on his mind. The more you insist, the more likely that he’ll refuse to talk. Instead, let him attempt to solve things by himself. At the same time, remind him that you’re always there for him should he seek advice or help. Show respect for your teenager’s privacy(隱私). Never read him his mail or listen in on personal conversions.
Teach your teenager that the family phone is for the whole family. If your child talks on the family’s telephone for too long, tell him he can talk for 15 minutes, but then he must stay off the phone for at least an equal period of time. This not only frees up the line so that other family members can make and receive calls, but teaches your teenager moderation (節(jié)制). Or if you are open to the idea, allow your teenager his own phone that he pays for with his own pocket money or a part-time job.
小題1:Why is it not easy being a teenager or a parent of a teenager?

A．Because the teenager is very naughty.

B．Because the parent always expects a lot from the child.

C．Because you can make your child feel hurt, or misunderstood by what you say without realizing it yourself.

小題3:The last paragraph is about how to teach a teenager        .

A．to use the phone in a sensible way	B．to pay for his own telephone
C．to share the phone quickly	D．to answer the phone quickly

小題4:What should parents do in raising a teenager according to the text?

A．Not allow him to learn driving or take drugs.

B．Give him advice only when necessary.

C．Let him have his own telephone.

D．Not talk about personal things with him.

Pigs are always considered dirty animals because they roll in mud．But in fact they prefer  being quite clean．They cover themselves with mud to help stay cool．During cooler weather,  they prefer to stay clean．So do elephants,who also cover themselves in dust or mud to keep cool． When they find a place with clean water they will take a bath，using their long noses to give  themselves—or each other—a nice shower
Some animals use dust to get clean．Chinchillas (南美洲栗鼠) have very fine fur． They don`t like to take water baths because water is not warm enough for them．So, instead, they roll  around in fine dust．The dust helps to keep their fur and skin dry．This protects them from disease
Usually, a small bird is a light meal for a crocodile．But when a crocodile wants its teeth  cleaned．it lies on the ground with its mouth open．The crocodile bird goes in and picks out any  parasites(寄生蟲)between the crocodile`s teeth or under its tongue．The crocodile gets its mouth cleaned，and the crocodile bird gets dinner．
You wouldn`t think fish would need baths．But some undersea parasites live under the  fish`s skin．“Cleaner”fish，like the wrasse(隆頭魚)，help take them away．The wrasse stands on its head and dances to signal a big fish that it is ready to go into the cleaning business．The big fish will stop moving and open its mouth wide so the wrasse can swim inside and pick out  parasites and bits of food．

The oil resources which are left will not last very long. This means that all vehicles such as cars, trains, buses, planes and ships that need oil to work will not be able to run. So it will be necessary to develop a new system of transport which uses a fuel more than oil. Electric vehicles are one possibility. In Britain, most families have at least one car and this car is used every day. It could be that only one person in the family drives the car to work or for shopping. The number of cars on the road which are almost empty perhaps helps to explain why the oil is used up so quickly. The family car is a very useful form of transport but it is also a great waste of energy, especially if it is compared with buses or trains. Much petrol is used by a car which is traveling at 120 kilometers an hour. Clearly, it would be better if there were fewer cars on the road and more speed limits so that the oil which is left will last as long as possible.
About 25% of Britain’s total consumption of energy is domestic—it is used only in the home. Just over 20% is used for transport. Most of the energy is used in industry. It is difficult to suggest any possible energy conservation in industry because many of the suggestions would mean that some people would lose their jobs. It is important that industry produces the same amount of products using the same amount of workers.
Obviously, conservation is not going to be the answer to the energy crisis（危機(jī)）. The most it can do is to give more time for a better solution to be found. The more time which is available for new sources of energy to be developed, the better it is because there is still a lot of work to be done in order to find suitable, safe methods of producing energy.
小題1:In Britain, what reason could help to explain why oil is used up very quickly?

A．People use cars every day.

B．Most families have at least one car.

C．Many cars on the road are almost empty.

D．Electric vehicles are used.

小題2:Which of the following is true?

A．Compared with buses and trains, the family car is useful and can save energy.

B．A car driving at the speed of 80 kilometers per hour uses half as much petrol as a car traveling at 160 kilometers per hour.

C．It is possible for people to develop vehicles.

D．Limitation of the number of cars on the road and their speed will help the oil last longer.

小題3:What does the underlined word “domestic” mean in Paragraph Two?

A．For household use.	B．On the road.
C．Slow driving.	D．Fast driving.

小題4:What is a better way to solve the problem of the energy crisis?

A．Governments should cut down the number of family cars on the road.

B．The speed of vehicles must be limited.

C．New sources of energy should be found and developed.

D．Factories should cut down on production.

Many teenagers feel that the most important people in their lives are their friends. They believe that their family members, especially their parents, don’t know them as well their friends do. In large families, it is often for brothers and sisters to fight with each other and then they can only go to their friends for advice. It is very important for teenagers to have one good friend or many friends. Even when they are not with their friends, they usually spend a lot of time talking among themselves on the phone. This communication is very important in children’s growing up, because friends can discuss something difficult to say to their family members.
However, parents often try to choose their children’s friends for them. Some parents may even stop their children from meeting their good friends. The question of “choice” is an interesting one. Have you ever thought of the following questions?
Who choose your friends?
Do you choose your friends or your friends choose you?

Animals Can Sense Natural Disasters
Among the dead in South Asia’ s tsunami（海嘯）were many tourists at Sri Lanka’ s national wildlife park at Yala. But very few of the park’s animals — elephants, buffaloes, monkeys and wild cats — appear to have died. There are theories that animals can sense natural disasters and run away to safety.
First, it’s possible that the animals may have heard the quake before the tsunami hit. The underwater burst produced sound waves known as infrasound（次聲）. Humans can’t hear infrasound, but many animals including dogs, elephants, tigers and pigeons can.
A second early warning sign the animals might have sensed is ground vibration（震動）. The great quake would have produced vibrational waves known as Rayleigh waves. These vibrations move through the ground like waves moving on the surface of the ocean but faster. They travel at ten times the speed of sound. The Rayleigh waves would have reached Sri Lanka hours before the water hit. Mammals, birds, insects and spiders can sense Rayleigh waves. So the animals at Yala might have felt the Rayleigh waves and then run to higher ground.
But what about humans? While we can’t hear infrasound, we can feel it, although we don’t necessarily know we’re feeling it. We also experience Rayleigh waves by special sensors in our joints（關(guān)節(jié)）, which exist just for that purpose. Sadly, it seems we don’t pay attention to the information when we get it. Maybe we screen it out because there’s so much going on before our eyes and in our ears.
小題1:Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit?

A．Because human beings cannot hear the infrasonic sound.

B．Because the animals were staying at a higher place in the park.

C．Because the animals were able to run much faster than human beings.

D．Because the animals might have picked up the danger signals and ran away.

小題2:Which of the statements about “Rayleigh waves” is true?

A．Rayleigh waves can be felt both by animals and human beings.

B．Rayleigh waves, just like infrasonic sound, can only be felt by animals.

C．Rayleigh waves are vibrational waves that usually cause quakes or tsunamis.

D．Rayleigh waves move on the ocean surface at a speed ten times that of sound waves.

小題3:According to the passage, which of the statement is true?

A．We can’t feel the infrasound so we can’t be informed of the danger.

B．We ignore the information of tsunami’s coming even though we can also get it.

C．We were so busy on our minds that we feel neither infrasound nor Rayleigh waves.

D．We can feel Rayleigh waves and infrasound so we can escape the danger like animals.
