Sonny opened his eyes wide, “Do you mean next time when I’m entering for the 60-metre race I should wish that Billy, Tony and Sandy would all fall asleep halfway?”
I was shocked, “But the tortoise didn’t wish that the hare would fall asleep!”
“He must have wished that,” Sonny said, “Otherwise how could he be so foolish as to race with the hare? He knew very well the hare ran a hundred times faster than he himself did.”
“He didn’t have such a wish,” I insisted. “He won the race by perseverance (坚忍不拔的), by pushing on steadily.”
Sonny thought a while. “That’s a lie,” he said. “He won it because he was lucky. If the hare hadn’t happened to fall asleep, the tortoise would never have won the race. He could be as steady as you like, or a hundred times steadier, but he’d never have won the race. That’s for sure.”
I gave up. Today’s children are not like what we used to be. They’re just hopeless.

小题5:D
解析
试题分析:本文是一位父亲和儿子关于龟兔赛跑的辨论,儿子的观点和父亲是完全不一样了,说明两代人的思想上有了代沟。
小题1:C 推理题。根据5,6段“He didn’t have such a wish,” I insisted. “He won the race by perseverance (坚忍不拔的), by pushing on steadily.”
Sonny thought a while. “That’s a lie,” he said. “He won it because he was lucky. If the hare hadn’t happened to fall asleep, the tortoise would never have won the race.说明我是想通过这个故事告诉儿子毅力的重要性,但是儿子有完全不同的观点,认为这个故事的假的。说明现在的孩子和以前的不一样了。故C正确。
小题2:D 细节题。根据倒数第二段第2行“He won it because he was lucky.说明他认为乌龟赢得比赛是幸运,是运气好,故D项正确。
小题3:B 推理题。根据第二段Do you mean next time when I’m entering for the 60-metre race I should wish that Billy, Tony and Sandy would all fall asleep halfway?”说明这几个孩子一定是以前和他一起跑步的孩子,故B正确。
小题4:D 推理题。根据文章最后一段I gave up. Today’s children are not like what we used to be. They’re just hopeless.说明作者已经认识到现在的孩子和以前的孩子已经不一样了,故D正确。
小题5:D 推理题。根据文章最后一段说明是Sonny的父亲从这次谈话中得出教训,就是现在的孩子和以前不一样了。故D正确、
点评:本文通过一个辩论说明代沟的存在。考查的题目以推理题为主,推断题测试考生在阅读基础上的逻辑推理能力,要求考生根据文章所述事件的逻辑关系,对未说明的趋势或结局作出合理的推断;或根据作者所阐述的观点理论,对文章未涉及的现象、事例给以解释。考生首先要仔细阅读短文,完整了解信息,准确把握作者观点。

“To provide enough power, we need certain methods with high energy density(密度)”,said Jae Kwon, assistant professor of electrical and computer engineering at MU.“The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS).Although nuclear batteries can cause concerns, Kwon said they are safe.
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
His new idea is not only in the battery’s size, but also in its semiconductor(半导体).Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”
Together with J.David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery.In the future, they hope to increase the battery’s power, shrink its size and try with various other materials.Kwon said that battery could be thinner than the thickness of human hair.
小题1:Jae Kwon gave examples in Paragraph 4_________.
A.to show chemical batteries are widely applied. |
B.to introduce nuclear batteries can be safely used. |
C.to describe a nuclear-powered system. |
D.to introduce various energy sources. |
A.uses a solid semiconductor | B.will soon replace the present ones. |
C.could be extremely thin | D.has passed the final test. |
A.science news report | B.book review |
C.newspaper ad | D.science fiction |
But what are stem cells? As we know, most cells in our bodies are designed to serve specific purposes – for example, a liver cell develops to work in the liver and cannot become a heart cell. But stem cells are different. They are very young, and in the laboratory scientists can grow them into different types of cell.
Claudia Castillo needed a new windpipe after getting a serious disease. Scientists from the University of Bristol in the UK took a donor windpipe, or trachea, from someone who had recently died. They used strong chemicals to remove the donor’s cells, leaving a tissue scaffold(组织支架). This was refilled with cells from Ms Castillo’s windpipe, and stem cells from her bone. After four days the cells had grown sufficiently for the windpipe to be transplanted into Ms Castillo.
Currently, transplant patients have to take drugs for the rest of their lives to prevent their bodies rejecting the new organs. These drugs can have bad side-effects, and do not always prevent rejection. But by using Ms Castillo’s own cells, doctors were able to trick her body into thinking the new windpipe was her own organ. Five months on, Claudia Castillo is in perfect health.
This ground-breaking procedure could be used in other transplant operations in the future. Scientists also believe stem cells might be used to treat Parkinson"s disease, Alzheimer"s disease, heart disease, stroke, arthritis, diabetes, burns and so on.
However, stem cell research is extremely controversial. The most effective stem cells do not come from adults but from embryos created in laboratories and which are just a few days old. Many people have religious or ethical objections to growing embryos, even if they can be used to cure diseases.
小题1:This transplant is considered the greatest medical breakthrough because _________.
A.this is the first organ transplant in the whole world |
B.the patient is in perfect health after the operation |
C.it is the first success with new stem cell technology |
D.the stem cells are from an embryo developed in a lab |
A.they are grown in the lab only |
B.they can grow into different types of cell |
C.they are designed for a specific purpose |
D.they can work in the liver not in the heart |
A.How Claudia survived in the operation |
B.How to remove the cells from the donor’s organ |
C.Why stem cells are needed in the transplant |
D.How the windpipe is transplanted |
A.Human bodies always reject transplanted organs even with their own cells |
B.The donor’s cells had to be removed because they were unhealthy |
C.The transplanted organ was refilled with the stem cells only |
D.Claudia will not have to take drugs to prevent rejection. |
A.controversial | B.confident |
C.conservative (保守的) | D.critical |
“The map says you have to turn when you see a large stone with a red circle,” said one of them.
“What do we do after the turn?” I asked 26 .
“It says we should see a tree. We are 27 to turn 20 meters north of it and dig.
We got there and dug. We had 28 at first digging but we got better and worked very 29 . My trousers were dirty but I kept digging 30 I hit something. It was a large metal box. We 31 the lock and looked inside. There was a letter. It read:
“The lesson you have learned will be very 32 . If you put as much 33 in anything you do as you did in finding the 34 , you will have found the key to making over 20 million dollars.”
This was a trick from my parents. I thought I would never forget this 35 birthday present.

Ocean water is full of salt— and salt water can hold up more weigh than fresh water. See for yourself!
You Will Need:
● 3 cups of warm water
● Measuring cup (量杯)
● Wide-mouthed jar
● Salt
● Spoon
● Raw (生的)potato
You Will Do:
1. Pour 1.5 cups of warm water into the jar.
2. Add 1/3 cup of salt.
3. Stir(搅拌) until the salt is completely dissolved.
4. Add another 1.5 cups of water. Pour it slowly over the back of the spoon into the jar so that the two liquid will not mix together.
5. Gently place the potato into the jar. Do not drop it.
What Will Happen:
The potato will sink— but only halfway!
Why?
Salt water is heavier than fresh water, so it will stay on the bottom. The fresh water will remain on top.
The potato is heavier than the fresh water, but it is lighter than the salt water. That is why the potato will sink halfway down.
小题1:In the experiment, what should you do right after you pour the water over the spoon?
A.Add the salt to the water. | B.Stir the salt into the water. |
C.Place the potato in the jar. | D.Pour warm water into thejar. |
A.It is easier to see what you are doing. |
B.It pushes the fresh water to the bottom. |
C.It will keep the water from coming out. |
D.It will keep the liquids from mixing together. |
A.Step 1 | B.Step 2 | C.Step 3 | D.Step 4 |
A.Carefully | B.Quickly | C.Secretly | D.Silently |
The elephant’s call will be familiar to most people, but the animals also give out growls (低吼). Their growls, however, are only partly audible (听得见的); two-thirds of the call is at frequencies that are too low to be picked up by our hearing. To learn more about the inaudible part of the growl, the team attached (附在……上面) a microphone sensitive to these low frequencies and a GPS tracking system to eight of the zoo’s female elephants. The researchers could then relate the noises the animals were making to what they were doing. Matt Anderson, who led the project, told BBC News, “We’re excited to learn how they interact and contact with one another.”
The team has already learned that pregnant females use this low frequency communication to announce to the rest of their long gestation (妊娠期) of over two years, in the last 12 days we see the low part of the growl, which we can’t hear. This we believe is to announce to the rest of the herd that the baby is upcoming,” said Dr Anderson.
The researchers believe that this also warns the elephants to look out for coming danger. “You may think that a baby calf of about 300 pounds would not be as open to predation (捕食) as other species,” he says. “But packs of hyenas (袋狼) are a big threat in the wild.”
Female elephants are only in season for around four days every four years and these calls can be heard by males more than two miles away.
小题1:Why some elephants’ call is called “secret language”?
A.Because it can’t be heard by human ears. |
B.Because it can only be heard by female elephants. |
C.Because people don’t know its meanings. |
D.Because people haven’t studied it completely. |
A.where the elephants usually go |
B.what the elephants’ growls really mean |
C.how mother elephants raise baby calves |
D.how elephants protect their babies. |
A.show the location where she is staying |
B.ask for help when she losses her way |
C.scare away the enemy |
D.let others know she will have a baby |
A.The elephants can speak like people. |
B.The wild elephants’ ways to fight against enemies. |
C.The “secret language” between elephants. |
D.The special life of female elephants. |
