A new report says the number of foreign students at colleges and universities in the United States increased by three percent last year. This has been the first obvious increase since 2001.
American schools last fall had 583,000 foreign students. The record is 586,000. That was set in 2002 after many years of gains. But after that the numbers fell. The terrorist attacks on September 11th, 2001 led to more visa (签证) requirements. Now stronger efforts are being made to get more foreign students to study in the United States.
China remained in second place in front of South Korea but behind India, which sent almost 84,000 students last fall. The number of Japanese fell sharply by nine percent, although it remained in fourth place.
There were three percent drops from Indonesia and Kenya, the only African country in the top twenty last year. But there were obvious increases from Saudi Arabia, Nepal and Vietnam. The number of Saudi students more than doubled, rising to nearly eight thousand.
For a sixth year, the University of Southern California in Los Angeles had the most foreign students. Columbia University in New York was second. Other schools in the top five were New York University, the University of Illinois and Purdue University.
Unlike American students in other countries, who often choose history and language study, the leading area of study in the USA was business and management. Second was engineering.
The new report also says more than 220,000 Americans studied in other countries. That was during the 2005-2006 school year. It was a record number, and an increase of eight and a half percent from the year before. But only five percent of them stayed for a full year. After 2002, the number of foreign students in the USA fell mainly because ____ .

In 1859，during the Gold Rush，a twenty- year-old immigrant（移民）from Bavaria named Levi Strauss stepped off the boat in San Francisco. He had with him a special cloth called Serge de Nimes that was later called denim in America. Levi Strauss hoped to sell the denim as material to make tents and covers for wagons to the men who were going to the goldfields to look for gold.
“You should have brought trousers to sell. In the goldfields we need strong trousers that don‘t wear out，”one young miner advised Strauss. So Levi Strauss took some of his denim to the nearest tailor and had him make the miner a pair of trousers. The miner was so pleased that he told other miners about the wonderful newcomer，Levi，and soon Levi Strauss had to open a shop，producing enough trousers for the miners. The miners wanted trousers that were comfortable to ride in and were low cut so that they could bend over easily to pick up the gold from under their feet. Besides they wanted the trousers to have big useful pockets. One miner complained that the gold in his pockets kept tearing them. So Levi put metal corners in the pockets to make them stronger. Very soon，miners and cowboys from all over came to get fitted up with Levi‘s trousers. Today more than a hundred years later， Levi’s trousers walk the world a Levi‘s blue jeans（牛仔裤）。The denim cloth was originally（起初）meant for____.
| A．making tent covers and wagons |

Language learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners. Most children will "obey" spoken instructions some time before they can speak, though the word "obey" is hardly accurate as a description of the eager and delighted cooperation usually shown by the child. Before they can speak, many children will also ask questions by gesture and by making questioning noises.
Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But sincethese can't be said to show the baby's intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation leads on to deliberate (有意的) imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.
It is a problem we need to get out. The meaning of a word depends on what a particular person means by it in a particular situation and it is clear that what a child means by a word will change as he gains more experience of the world.Thus the use at seven months of"mama" as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself, I doubt, however, whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds. Before children start speaking, _____.
| A．they need equal amount of listening |
| B．they need different amounts of listening |
| C．they are all eager to cooperate with the adults by obeying spoken instructions |
| D．they can't understand and obey the adult's oral instructions |
Children who start speaking late _____.
| A．may have problems with their listening |
| B．probably do not hear enough language spoken around them |
| C．usually pay close attention to what they hear |
| D．often take a long time in learning to listen properly |
A baby's first noises are _____.
| A．an expression of his moods and feelings |
| B．an early form of language |
| C．a sign that he means to tell you something |
| D．an imitation of the speech of adults |
The problem of deciding at what point a baby's imitations can be considered as speech _____.
| A．is important because words have different meanings for different people |
| B．is one that should be properly understood because the meaning of words changes with age |
| C．is not especially important because the changeover takes place gradually |
| D．is one that should be completely ignored (忽略) because children's use of words is often meaningless |
The author implies _____.
| A．parents can never hope to teach their children new sounds |
| B．even after they have learnt to speak, children still enjoy imitating |
| C．children no longer imitate people after they begin to speak |
| D．children who are good at imitating learn new words more quickly |
Can people change their skin color without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color.
The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the color of a dark-striped zebrafish（斑马鱼） to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebrafish skin color is determined by pigment cells, which contain melanin (黑色素). The number, size and darkness of melanin per pigment cell determine skin color.
It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation (变异) in the gene for melanin production. This results in less pigmented skin.
However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun (太阳光紫外线), which can cause skin cancer.
But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color without damaging it like chemical treatment did on Michael Jackson.The passage mainly tells us that ________.
| A．people can not change their skin color without any pain |
| B．the new discovery could lead to research into ways to change skin color safely |
| C．pop king Michael Jackson often changed his skin color as he liked |
| D．scientists have found out that people’s skin color is determined by the gene |
It can be inferred from the passage that ________.
| A．nowadays people who want to change their skin color have to suffer a lot from the damage caused by the chemical treatment |
| B．Europeans and Africans have the same gene |
| C．the new discovery could help to find medical treatments for skin cancer |
| D．there are two kinds of genes |
Scientists have done an experiment on a dark-striped zebrafish in order to ________.
| A．find the different genes of humans’ |
| B．prove the humans’ skin color is determined by the pigment gene |
| C．find out the reason why the Africans’ skin color is dark |
| D．find out the ways of changing people’s skin color |
The reason why Europeans are light-skinned is probably that _____
| A．they are born light-skinned people |
| B．light-skinned Europeans have mutation in the gene for melanin production |
| C．they have fewer activities outside |
| D．they pay much attention to protecting their skin |
The writer’s attitude towards the discovery is ________.
| A．neutral | B．negative | C．positive | D．unconcerned |
