You speak, write a letter, and make a telephone call. Your words carry a message. People communicate (交际) with words. But do you think you can communicate without words? A smile on your face shows you are happy and friendly. Tears in your eyes tell others that you are sad. When you raise your hand in class, the teacher knows you want to say something or ask questions. You shake your head, and people know you are saying “No. ” You nod (点头) , and people know you are saying “Yes. ” Other things can also carry message. For example, a sign (标志) at the bus helps you know which bus to take. A sign on the door tells you where to go in or out. Have you ever noticed that a lot of signs around you and that you receive messages from them all the time?
People can communicate in many other ways. An artist can use his drawing to tell about beautiful mountains, about the blue sea and many other things. Books are written to tell about all the wonderful things in the world and also about people and their ideas.
Books, magazines, TV, radio and films all help us communicate with others. They all help us to know what is going on in the world and what other people are thinking about.

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 |
There has been a dramatic increase in the number of natural disasters over the past few years, and it is assumed that global warming and climate change could cause even more disasters in the future. Some of the world’s leading cities are facing disasters like floods and heat waves.
London
London’s flood defences are getting older. Since 1982, the Thames Barrier(水闸)has protected the city from the threat of flooding, but it was only designed to last until 2030 and close once every two or three years. About 26 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not addressed.
There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property in London’s flood risk area, so large scale flooding would be disastrous.
Paris
Over a six week period in July and August 2003, more than 1 1,400—mainly elderly people—died in France from dehydration(脱水)and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity(强度)are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?
One solution is to have air-conditioners installed in elderly care homes. But this is considered a short-term solution, as the increase in demand for electricity also increases carbon emissions(排放).
In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower,” which uses a covering of bamboo to act as a natural air-conditioner.
Shanghai
Shanghai is the fastest growing city on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.
An estimated 250，000 people move to Shanghai every year in search of work, placing extra demands on energy consumption. China relies heavily on coal—fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.What problem should be settled now in London?
| A．How to protect the city’s property |
| B．Where to build its flood defences |
| C．How to use the Thames Barrier to protect the city |
| D．How to improve the function of the old flood defences |
Which of the following measures can’t solve the heat wave disaster in Paris?
| A．Putting up new types of buildings with a covering of bamboo |
| B．Having air-conditioners installed in elderly care homes |
| C．Forbidding the city to build“Flower Tower” |
| D．Encouraging architects to design new types of buildings |
The major threats to Shanghai are ．
| A．increasing population and coal-fired power stations |
| B．rising sea levels and typhoons |
| C．extremely high temperature and rising sea levels |
| D．extra demands on energy consumption and typhoons |
The purpose of the passage is ．
| A．to tell us how to protect the big cities |
| B．to give advice on how to defend natural disasters |
| C．to explain what causes flood and heat waves |
| D．to warn us of the increasing natural disasters in big cities |
Which of the following would be the best title for the passage?
| A．Big Cities Facing Big Disasters |
| B．Big Disasters in the Future |
| C．The Increase of Natural Disasters |
| D．Solutions to Natural Disasters |
