答案
小题1:A
小题2:D
小题3:B
小题4:A
解析
小题1:A 推理题。文章第一句Warm water freezes more quickly than cold water.温水比冷水更快结冰，热水的温度比冷水的温度要高，而结冰的时候都是零度了，这说明热水的温度降的更快。故A正确。
小题2:D 细节题。根据文章第二行But few people believed him until 1970.人们直到20世纪70年代才相信这个理论。20实际70年代属于20世纪的晚期，故D正确。
小题3:B 细节题。根据文章4,5行Dr Kill filled an open oil pail(桶) with cold water. He filled another with warm water. He put both in the same low temperature. The warm water froze first.说明温水更快结冰，那么是在冷水结冰之前就结冰了，故B正确。
小题4:A 细节题。根据文章倒数3,4行Some of the warm water changed into vapor. This meant that less of the warm water was left to be frozen.说明部分热水变成了水蒸气，留下的热水变少了，这才是热水比冷水结冰更快的原因。故A正确。

On 26th January, 2009, the biggest earthquake in India took the lives of 25,000 people. In the morning, when everybody was enjoying holiday, the earthquake began, It was about 7.5 on the Richter scale. "There is nothing left between the sky and the earth any more. Everything has been pulled down. " said one of the villagers alive. " There is no water, no food and no one has come to help."
Nobody died in Pakistan, a country next to India. The City of Lahore was lucky. In Lahore American School, where I was studying, all of the students were safe. They were in the field, so most children didn"t feel anything. The earthquake was felt by the teachers that were on the second floor. However, though Mrs Young was also on the second floor, she didn"t feel anything. She didn"t know what happened until a teacher told her about it. Those teachers who were on the other floors had different feelings. Mr Emond, the maths teacher from Australia, said that when the earthquake started he thought there was something wrong with him, but then another teacher said that it was an earthquake. After those words Mr Emond felt better. Mrs Davis and Mr Frost didn"t feel anything either.
My mother didn"t feel anything. She didn"t even know that it was an earthquake till she saw a shaking light. My dad saw the computer shaking and then he looked out of the window and saw many people going out.

Some people think we should establish a standard with our kids and give them something for meeting this standard as a reward. Punishment is given out in much the same way, but it’s used when certain standards of performance, behavior, etc. have not been met. Kids will often become more dutiful when threatened with punishment, and work harder when promised a valuable reward. The problem is what happens when you aren’t around.
To develop responsible, self-disciplined kids, parents need to promote certain ideas. One of these ideas is that everyone pitches in and helps in your family. Another idea is that there can be enjoyment in doing any task if we choose to make it so. When a task is for a worthy cause (our family can enjoy the house more because I helped clean it), this message can have a big impact.
This is how we help our kids develop a sense of responsibility. When our children develop this responsibility, they’ll be more disciplined, and they’ll control their emotions better. When we give rewards to our kids, we reduce the sense of responsibility. We also create children who may temporarily perform to a certain standard, but who aren’t likely to continue the performance without the carrot hanging in front of them.
“Rewards and punishment can change behavior for a while, but they cannot change the person who engages in the behavior,” said Alfie Kohn, author of Punished by Rewards. “Good values have to be grown from the inside out.” Parents can help give their children a sense of shared responsibility and discipline which can last a life time. The real rewards that your children receive will be their readiness for the complex and demanding world that waits for them—a world that rewards those who have learned the secrets of discipline responsibility. So keep those shiny rewarding to yourself, and let your kids find their own rewards.
小题1:According to the passage, when children are threatened with punishment, ______.
| A．they may lose interest in their work |
| B．the results will be worse than usual |
| C．they may change to another person |
| D．they may appear to be well-behaved |
| A．apologies | B．aims | C．rewards | D．doubts |
| A．never pay attention to the way their children do things |
| B．show their children how to behave by example |
| C．help their children establish good values |
| D．never punish their children |
| A．Should parents reward their children? |
| B．Do you often reward your children? |
| C．When should parents reward their children? |
| D．What can parents reward their children with? |
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past. ”We were surprised by just how positive today’s young people seem to be about their families, ”said one member of the research team. ”They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There’s more negotiation(商议) and discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat. ”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat the children as friends. ”My parents are happy to discuss things with me and willing to listen to me, ”says 17-years-old Daniel Lazall. ”I always tell them when I’m going out clubbing. As long as they know what I’m doing, they’re fine with it. ”Susan Crome, who is now 21, agrees. ”Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that. ”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenagers’ rebellion is not rooted in real facts. A researcher comments, ”Our surprise that teenagers say they get along well with their parents comes because of a brief period in out social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over. ”

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 go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys" brains. When the brain" s temperature was 10°C, 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.

It was a lovely spring day. We could see dandelions(蒲公英）popping through the grass in bunches, as if a painter had touched our landscape with bits of gold. I watched my mother carelessly bend down by one of the bunches. "I think I am going to dig up all these weeds, "she said. "From now on, we"ll have only roses in this garden. "
"But I like dandelions, "I protested. "All flowers are beautiful-even dandelions!"
My mother looked at me seriously. "Yes, every flower gives pleasure in its own way, doesn"t it?" she asked thoughtfully. I nodded. "And that is true of people, too, " she added.
When I realized that she had guessed my pain, I started to cry and told her the truth.
“But you will be a beautiful narrator, ”she said, reminding me of how much I loved to read stories aloud to her.
Over the next few weeks, with her continuous encouragement, I learned to take pride in the role. The big day finally came. A few minutes before the play, my teacher came over to me. “Your mother asked me to give this to you, ”she said, handing me a dandelion. After the play, I took home the flower, laughing that I was perhaps the only person who would keep such a weed.
