Language is always changing. In a society where life continues year after year with few changes, the language does not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.
There are several major(主要) language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families.The early language had ________.

| B．languages really don't want to change |
| C．language really with changes in society |
| D．Spanish and English change |
Energy independence. It has a nice ring to it. Doesn’t it? If you think so, you’re not alone, because energy independence has been the dream of American president for decades, and never more so than in the past few years, when the most recent oil price shock has been partly responsible for kicking off the great recession(经济衰退).
“Energy independence” and its rhetorical (修辞的) companion “energy security” are, however, unreliable concepts that are rarely thought through. What is it we want independence from exactly?
Most people would probably say that they want to be independent from imported oil. But there are reasons that we buy all that oil from elsewhere.
The first reason is that we need it to keep our economy running. Yes, there is a trickle(涓涓细流) of bio-fuel(生物燃料) available, and more may become available, but most biofuels cause economic waste and environmental destruction.
Second, Americans have basically decided that they don’t really want to produce all their own oil. They value the environmental quality they preserve over their oil imports from abroad. Vast areas of the United States are off-limits to oil exploration and production in the name of environmental protection. To what extent are Americans really willing to tolerate the environmental impacts of domestic(国内的) energy production in order to cut back imports?
Third, there are benefits to trade. It allows for economic efficiency, and when we buy things from places that have lower production costs than we do, we benefit. And although you don’t read about this much, the United States is also a large exporter of oil products, selling about 2 million barrels of petroleum products per day to about 90 countries.
There is no question that the United States imports a great deal of energy and, in fact, relies on that steady flow to maintain its economy. When that flow is interrupted, we feel the pain in short supplies and higher prices. At the same time, we get massive economic benefits when we buy the most affordable energy on the world market and when we engage in energy trade around the world.What does the author say about energy independence for America?
| A．It sounds very attractive. |
| B．It will bring oil prices down. |
| C．It ensures national security. |
| D．It has long been everyone’s dream. |
What does the author think of bio-fuels?
| A．They keep America’s economy running healthily. |
| B．They cause serious damage to the environment. |
| C．They prove to be a good alternative(substitute) to petroleum. |
| D．They do not provide a sustainable energy supply. |
Why does America rely heavily on oil imports?
| A．It wants to expand its storage of raw oil. |
| B．Its own oil reserves are quickly running out. |
| C．Its own oil production falls short of demand. |
| D．It wants to keep its own environment untouched. |
What does the author say about oil trade?
| A．It makes for economic recession． |
| B．It brings benefit only to the sellers． |
| C．It improves economic efficiency． |
| D．It saves the cost of oil exploration． |
What is the author’s purpose in writing the passage?
| A．To explain the increase of international oil trade. |
| B．To raise Americans’ awareness of the energy crisis. |
| C．To argue for America’s dependence on oil imports. |
| D．To stress the importance of energy protection. |
About ten years ago, a young and very successful businessman named Josh was traveling down a Chicago neighborhood street. He was going a bit too fast in his shiny, black, 12 cylinder Jaguar XKE, which was only two months old.
He was watching for kids rushing out from between parked cars and slowed down when he thought he saw something. As his car passed, no child came out, but a brick sailed out and—WHUMP! —it hit the Jag’s shiny black side door! Immediately Josh stopped the car, jumped out, seized the kid and pushed him up against a parked car. He shouted at the kid, “What was that all about and who are you? That’s my new Jag, that brick you threw is gonna cost you a lot of money. Why did you throw it? ”
“Please, mister, please……I’m sorry! I didn’t know what else to do! ” begged the youngster. “I threw the brick because no one else would stop! ” Tears were streaming down the boy’s face as he pointed around the parked car. “It’s my brother, mister, ” he said. “He rolled of the curb (路沿) and fell out of his wheelchair and I can’t lift him up. ”Sobbing, the boy asked the businessman, “ Would you please help me get him back into his wheelchair? He’s hurt and he’s too heavy for me. ”
Moved beyond words, the young businessman tried hard to swallow the rapidly swelling lump in his throat. Straining, he lifted the young man back into the wheelchair and took out his handkerchief and wiped the scrapers and cuts, checking to see that everything was going to be OK. He then watched the younger brother push him down the sidewalk toward their home.
It was a long walk back to the black, shining 12 cylinder Jaguar XKE—a long and slow walk. Josh never did fix the side door of his Jaguar. He kept the dent (凹痕) to remind him not to go through life so fast that someone has to throw a brick at him to get his attention.

Not long ago, people thought babies were not able to learn things until they were five or six months old. Yet doctors in the United States say babies begin learning on their first day of life. Scientists note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other human beings.
One study shows that babies can learn before they are born. The researchers placed a tape recorder on the stomach of a pregnant (怀孕的)woman. Then, they played a recording of a short story. On the day the baby was born, the researchers attempted to find if he knew the sounds of the story repeated while in his mother. They did this by placing a device in the mouth of the newborn baby.
The baby would hear the story if he moved his mouth one way. If the baby moved his mouth the other way, he would hear a different story. The researchers say the baby clearly liked the story he heard before he was born. They say the baby would move his mouth so he could hear the story again and again.
Another study shows how mothers can strongly influence social development and language skills in their children. Researchers studied the children from the age of one month to three years. The researchers attempted to measure the sensitivity of the mothers. The women were considered sensitive if they supported their children’s activities and did not interfere ( 干预）unnecessarily. They tested the children for thinking and language development when they were three years old. Also, the researchers observed the women for signs of depression.The children of depressed women did not do as well in tests as the children of women who did not suffer
from depression. The children of depressed women did poorly in tests of language skills and understanding what they hear.
These children also were less cooperative and had more problems dealing with other people. The researchers noted that the sensitivity of the mothers was important to the intelligence development of their children. Children did better when their mothers were caring, even when they suffered from depression.According to the passage, which of the following is NOT the factor that influences intelligence development in babies?
| A．The environment. |
| B．Mother's sensitivity. |
| C．Their peers (同龄人) |
| D．Education before birth. |
What is the purpose of the experiment in which newborn babies heard the stories?
| A．To prove that babies can learn before they are born. |
| B．To prove that babies can learn on the first day they are born. |
| C．To show mothers can strongly influence intelligence development in their babies. |
| D．To indicate early education has a deep effect on the babies' language skills. |
Which group of children did the worst in tests of language skills?
| A．The children of depressed mothers who cared little for their children. |
| B．The children of women who did not suffer from depression. |
| C．The children of depressed but caring mothers. |
| D．Children with high communication abilities. |
What is the main idea of the passage?
| A．Scientific findings about how babies develop before birth. |
| B．Scientific findings about how time has an effect on babies' intelligence. |
| C．A study shows babies are not able to learn things until they are rice or six months old. |
| D．Scientific findings about how intelligence develops in babies. |
Moral（道德的）science is taught as a subject in most schools but with little effect. Perhaps part of the problem lies in the fact that morality is not a science, strictly speaking. It is too much of a social phenomenon, and also has too much of the personal and subjective things mixed within. Besides, morality itself changes with generations. So it is impossible to be defined in a textbook.
I remember sitting through forty minutes of moral lessons, which told stories about little children who never told lies and were rewarded for their goodness. It had little effect and left no impression on me, though.
If moral science has to be taught as a subject in schools, it needs a participatory(参与其中的) approach. When you tell a child about morals, you also have to deal with social norms（规范）and cultural differences. You have to explain that morality can be subjective, and be able to co-exist in society. You will probably have to refer to the morals of the present time.
The best way to tell a child how to live is to show him what is valued. If a child likes his friend, you have to make the child think about why. Once the child notices and recognizes goodness in others, he or she is likely to develop it as well.
In fact, children learn most of their morals by watching people around them. They absorb behavior patterns from teachers and older students. They watch to see what is rewarded and who is punished. They learn on the sports field and through social work. Moral science lessons should simply consist of letting them live and interact, and watch you support correct values and reward good behavior. Which is NOT the reason that moral science is taught in schools but with little effect?
| A．Morality doesn’t strictly belong to a science. |
| B．Morality is more like a social phenomenon. |
| C．Different generations have different moral ideas. |
| D．Morality can’t be written down in textbooks. |
The author describes his own experience of having moral lessons in order to _____.
| A．explain telling lies is not moral for little children. |
| B．advise people should be rewarded for their goodness. |
| C．show he has no opinions about moral science. |
| D．prove moral lessons in schools have little effect. |
When you tell a child about morals, you should________.
| A．tell him about social norms and cultural differences. |
| B．teach him to share personal moral ideas with others. |
| C．explain that nobody can influence his moral ideas. |
| D．say that the present morals are likely to be changed. |
What is the last paragraph mainly about?
| A．The value of teachers’ setting a good example. |
| B．The best way of teaching children about morals. |
| C．The influence of people’s behavior on morals. |
| D．The importance of rewarding good behavior. |
