What’s that smell? Do you hear that noise? Taste this! Look at me! Feel this, isn’t it soft? When you hear, or even use these phrases, you probably don’t stop to think about why we use them. Well, it’s because of our senses. Without us even knowing, our sense organs (nose, eyes, ears, tongue, and skin) are taking in information and sending it to the brain for processing. If we didn’t have them, we would not be able to smell, see, hear, taste, or touch anything!
Senses are the physical means by which all living things see, hear, smell, taste, and touch. Each sense collects information about the world and detects changes within the body. Both people and animals get all of their knowledge from their senses, and that is why senses are so important.
All senses depend on the working nerve system. Our sense organs start to work when something stimulates（刺激） special nerve cells, called receptors, in a sense organ. Once stimulated, the receptors send nerve impulses along sensory nerves to the brain. Your brain then tells you what to do. For example, your sound receptors are often attacked by billions of sound waves. When these signals reach the part of the brain called the cerebral cortex（大脑皮层）, we become conscious of the sounds.

One of our biggest fears nowadays is that our kids might some day get lost in a “sea of technology” rather than experiencing the natural world. Fear – producing TV and computer games are leading to a serious disconnect between kids and the great outdoors, which will change the wild places of the world, its creatures and human health for the worse, unless adults get working on child’s play.
Each of us had a place in nature we go sometimes, even if it was torn down. We cannot be the last generation to have that place. At this rate, kids who miss the sense of wonder outdoors will not grow up to be protectors of natural landscapes. “If the decline in parks use continues across North America, who will defend parks against encroachment（蚕食）?” asks Richard Louv, author of Last Child in the Woods.
Without having a nature experience, kids can turn out just fine, but they are missing out a huge enrichment of their lives. That applies to everything from their physical health and mental health, to stress levels, creativity and cognitive（认知的）skills. Experts predict modern kids will have poorer health than their parents—and they say a lack of outside play is surely part of it; research suggests that kids do better academically in schools with a nature component and that play in nature fosters（培养）leadership by the smartest, not by the toughest. Even a tiny outdoor experience can create wonder in a child. The three – year – old turning over his first rock realizes he is not alone in the world. A clump of trees on the roadside can be the whole universe in his eyes. We really need to value that more.
Kids are not to blame. They are over – protected and frightened. It is dangerous out there from time to time, but repetitive stress from computers is replacing breaking an arm as a childhood rite（仪式）of passage.
Everyone from developers to schools and outdoorsy citizens, should help regain for our kids some of the freedom and joy of exploring, taking friendship in fields and woods that cement（增强）love, respect and need for the landscape. As parents, we should devote some of our energies to taking our kids into nature. This could yet be our greatest cause..

For thousands of years, the most important two buildings in any British village have been the church and the pub. Traditionally, the church and the pub are at the heart of any village or town, where the people gather together to socialize and exchange news.
As a result, British pubs are often old and well preserved. Many of them have become historic sites. The most famous example is the pub in the city of Nottingham called “Ye O
lde Trip to Jerusalem”, which dates back to the year 1189 AD and is probably the oldest pub in England.
However, British pubs are not just for kings and queens; they welcome people from all classes and parts of society. On a cold night, the pub’s landlord or landlady can always find a warm place for you by the fire. There is always honest and hearty food and plenty of drink available at an affordable price.
That’s how things used to be. Things are beginning to change. It is said that the credit crunch(信贷紧缩) is causing 39 British pubs a week to go out of busi
ness. People do not have enough spare money to spend on beer. Recently, the UK government banned smoking in all pubs, and that may also have affected the number of customers going to pubs.
This decline is happening despite the fact that in 2005 the UK government started to allow pubs to stay open after 1l pm. Previously, with 1l pm as closing time, customers would have to drink quite quickly, meaning they sometimes got more drunk than they would if allowed to drink slowly. The British habit of drinking a lot very quickly is known as “binge drinking”, and it causes long-term health problems for people and problems with violent crime for communities.
In order to save their businesses, pubs are trying to change with the market. British pubs now offer something for everyone. A lot of pubs used to be “Working Men's Clubs”, meaning that women could not usually enter. Today, however, women can freely enter 99% of pubs without experiencing any problems. Perhaps things are changing for the better after all..The passage mainly tells us something about
| A．the past and present of British pubs | B．the decline of British pubs |
| C．the long history of British pubs | D．the importance of British pubs |
.Which may not be the cause of the decline of British pubs?
| A．The credit crunch. | B．The present closing time. |
| C．The ban of smoking. | D．Having no spare money. |
.. We can infer from the passage that
| A．British people used to like drinking slowly |
| B．closing the pubs early will reduce social problems |
| C．binge drinking means drinking less beer |
| D．British government aims to discourage people from binge drinking |
.We can see from the last paragraph that the author ________
| A．is against the admission of too many women to the pubs |
| B．holds an optimistic attitude towards the British pubs |
| C．thinks that women in the pubs will cause less social problems |
| D．thinks that British pubs should offer everything you need |
Modern inventions have speeded up people’s lives amazingly. Motor-cars cover a hundred miles in little more than an hour, aircraft cross the world inside a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every year motor-cars are produced which go even faster and each new computer boasts (吹嘘) of saving precious seconds in handling tasks.
All this saves time, but at a price. When we lose or gain half a day in speeding across the world in an air
plane, our bodies tell us so. We get the uncomfortable feeling known as jet-lag; our bodies feel that they have been left behind in another time zone. Again, spending too long at computer results in painful wrists and fingers. Mobile phones also have their dangers, according to some scientists; too much use may transmit harmful radiation into our brains, a consequence we do not like to think about.
However, what do we do with the time we have saved? Certainly not rel
ax, or so it seems. We are so accustomed to constant activity that we find it difficult to sit and d
o nothing, or even just one thing at a time. Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world.
There was a time when some people’s lives were devoted simply to the cultivation of the land or the care of cattle. No multi-tasking there; their lives went on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so, we must think of the hard
tasks our ancestors faced: they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone. Modern machinery has freed people from that primitive existence. The new products become more and more time-saving because .
| A．the manufacturers boast a lot | B．time is limited |
| C．the prices are increasingly high | D．our love of speed seems never-ending |
What does “the days” in Paragraph 3 refer to?
| A．Simple life in the past. | B．Imaginary life. |
| C．Times of inventions. | D．Time for constant activity. |
. What is the author’s attitude towards the modern technology?
| A．Critical. | B．Optimistic. | C．Objective. | D．Negative. |
. What does the passage mainly discuss?
| A．The present and past times. | B．Modern technology and its influence. |
| C．Imaginations and inventions. | D．Machinery and human beings. |
It was a village in India. The people were poor. However, they were not unhappy. After all, their forefathers had lived in the same way for centuries.
Then one day, some visitors from the city arrived. They told the villagers there were some people elsewhere who liked to eat frog’s legs. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.
This seemed like money for nothing. There were millions of frogs in the fields around, and they were no use to the villagers. All they had to do was catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able to dream of a better future. But the dream didn’t last long.
The change was hardly noticed at first, but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often, and, there seemed to be more insects around lately.
The villagers decided that they couldn’t just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides (杀虫剂）and medicines. Soon there was no money left.
Then the people realized what was happening. It was the frog. They hadn’t been useless. They had been doing an important job — eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.
Now, the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning..

The need to feed a growing population is putting much pressure on the world’s supply of water. With 97% of the world’s water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage seems strange to someone fortunate enough to live in a high rainfall country, many of the world’s agricultur
al industries experience constant water shortages.
Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution (重新分配) are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.
This is particularly troubling for countries with agricultural industries in areas dependent on irrigation. In Texas, farmers’ overuse of irrigation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed.
Saudi Arabia’s attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry..
