Downing the last drop of an expensive famous brand H2O as well as remembering to throw the empty bottle in the recycling bin, makes you feel pretty good about yourself, right? It shouldn’t. Even when the bottles are recycled, there are all kinds of other consequences of swallowing bottled water, says Melissa Peffers, the air-quality program manager for Environmental Defense.
The containers are often filled in faraway lands, then shipped from abroad, and stored in refrigerators at your local store. Compare that with the influence on environment of turning on your tap, filling a glass, and drinking up!
Anyone who is choosing bottled water for health reasons is misguided, says Peffers, “Most bottled water is just tap water.” And what comes out of your tap is carefully monitored to follow the strict rules. Consider another fact that bottled water is surprisingly expensive, especially when compared with the alternative, which is almost free, and it is astonishing that America’s desire for bottled water seems impossible to satisfy, reaching nearly 30 billion bottles a year.
“My parents’ generation never had bottled water,” says Isabelle Silverman, an Environmental Defense legal adviser. She has made a commitment to going bottle free. “You don’t need to fetch it home from the store, and it’s cheaper,” she adds.
Bottled water’s role as a status symbol needs to change, Peffers points out. So when a waiter at an expensive restaurant offers “And what’s your drink?” that’s no reason to forget your conviction(信念). “Don’t be afraid to say, ‘I’ll have tap.’ Say it loud enough that the other tables nearby can hear you,” Peffers says. “And then spend that money on a dessert.”

Mark and his brother Jason both were looking at the shining new computer enviously, Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.
“Dad will be really mad if he finds out you’ve been playing with his new computer.” Jason said, “He told us not to touch it.”
“He won’t find out,” Mark said. “I’ll just have a quick look and shut it down.”
Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, “so don’t touch it under any circumstances.” But his father’s warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colors, shifting and changing and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.” “Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead.” A new message appeared on the screen: “ENTER NAMES
VOYAGER 1:…
VOYAGER 2:…”
Mark’s fingers flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED. START TRANSPORT PROGRAM. AUTO-RETRIEVE INITIATED (自动回收程序已启动).”
The screen turned even brighter and a noise suddenly rose in volume.
“I think we’d better shut it off, Mark,” Jason yelled, reaching for the power switch. He was really frightened.
But his hand never reached the switch. A single beam of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒) , until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.
“TRANSPORT SUCCESSFUL. DESTINATION (目的地)：MARS. RETRIEVE DATE: 2025.”

It’s you and I who are to blame for the state of the earth. No question about it. It’s our life-style that is threatening life on Earth, so we must make the changes. The good news is that many of those changes are really quite simple, even enjoyable, but for every careful step we take as individuals, we must press government and industry to take a big step on our benefit. And we must start now. Tomorrow’s too late.
My aim this year is to persuade as many of my friends and colleagues as possible to choose the train, and leave their cars behind too. My gardens have been pesticide(杀虫剂)–free zones for years and I enjoy seeing more wildlife on my doorstep as a result; I’ve tried to reduce my contribution to water pollution too, by using environment-friendly, phosphate(磷)–free washing powder , and by no longer thinking of the toilet as a suitable waste-disposal(处理) point .
I ran after a young lady through town recently to give her back the piece of paper she had carelessly thrown away. She disappeared into a shop, and when I followed her inside and made my presentation, she was doubly embarrassed--she worked there, and the boss gave her a ticking–off too. I’ve started asking fellow drivers at gas stations why they aren’t using unleaded (无铅的) petrol . These are small things, but we have to start somewhere, and every little does help.

Half of the world’s population is affected by Asian monsoons（季风）, but monsoons are difficult to predict. American researchers have put together a 700-year record of the rainy seasons, which is expected to provide guidance for experts making weather predictions.
Every year, damp air masses，known as monsoon，produce large amounts of rainfall in India, East Asia, Northern Australia and East Africa. All this wet air is pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south.
According to Edward Cook , a weather expert at Columbia University in New York., the complex nature of the climate systems across Asia makes monsoons hard to predict. In addition, climate records for the area are too recent and not detailed enough to be of much use. Therefore, he and a team of researchers spent more than fifteen years traveling across Asia, looking for trees old enough to provide long-term records. They measured the rings, or circles, inside thousands of ancient trees in more than 300 places.
Rainfall has a direct link to the growth and width of rings on some kinds of trees. The researchers developed a document they are calling a Monsoon Asia Drought Atlas. It shows the effect of monsoons over seven centuries, beginning in the 1300s.
Professor Cook says the tree-ring records show periods of wet and dry weather. “If the monsoon basically fails or is a very weak one, the trees affected by monsoons at that location might put on a very narrow ring. But if the monsoon is very strong, the trees affected by that monsoon might put on a wide ring for that year. So, the wide and narrow ring widths of the chronology that we developed in Asia provide us with a measure of monsoon variability.” With all this information, researchers say they can begin to improve computer climate models for predicting the behavior of monsoons.
“There has been widespread famine and starvation and human dying in the past in large droughts. And on the other hand, if the monsoon is particularly heavy, it can cause extensive flooding.” said Eugene Wahl, a scientist with America’s National Oceanic and Atmospheric Administration. “So, to get a sense of what the regional moisture patterns have been, dryness and wetness over such a long period of time in great detail, I would call it a kind of victory for climate science.”
【小题1】What’s the passage mainly about？
| A．The effects of Asian monsoons. |
| B．The necessity of weather forecast. |
| C．The achievements of Edward cook. |
| D．A breakthrough in monsoon prediction. |

| B．The Monsoon Asia Drought Atlas has a monsoon record for about 1,300 years. |
| C．The trees affected by monsoon grow fast if the monsoon is weak. |
| D．The rainfall might be low although the monsoon is strong in monsoon-affected areas. |
| A．determine the regional climate. |

Passage 1
The information Highway is the road that links computer users to a large number of on-line services; the Web, e-mail, and software, to mention just a few. Not long ago, the information Highway was a new road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems, forcing the system to close down for repair. Naturally, accidents will happen on such a crowed road, and usually victims are some files, gone forever. Then, of course, there’s Mr. Cool, with his new broad-band connection, who speeds down the highway faster than most of us can go. But don’t trick yourself; he pays for that speeding.
Passage 2

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.
【小题1】From paragraph 1 we learn that the villagers ________.
| A．worked very hard for centuries |
| B．dreamed of having a better life |
| C．were poor but somewhat content（满意的） |
| D．lived a different life from their forefathers |
| A．The frogs were easy money. |
| B．They needed money to buy medicine. |
| C．They wanted to please the visitors. |
| D．The frogs made too much noise. |
| A．The crops didn't do well. |
| B．There were too many insects. |
| C．The visits brought in diseases. |
| D．The pesticides were overused. |

Scientists say they now have proof to support the old-fashioned advice that it's best to sleep on a problem. They say sleep strengthens the memory and helps the brain organize the masses of information we receive each day.
Lead researcher Bob Stickgold at the Harvard Medical School said, "Sleep helps us draw rules from our experiences. It's like knowing the difference between dogs and cats even if it's hard to explain."
The US research team studied how well students remembered connections between words and symbols (象征) , reports New Scientist. They compared how the students performed if they had had a sleep between seeing the words and having the test, and if they had not slept. They found that people were better able to remember lists of related words after a night's sleep than after the same time spent awake during the day. They also found it easier to remember themes (主题) that the words had in common. But they forgot around one in four more themes if they had been awake. Prof. John Groeger, of Surrey University's Sleep Research Centre, said, "People have been trying for years to find out what the purpose of sleep is, as we know that only certain parts of it have a restorative (有助恢复的) value. " "We form and store huge numbers of experiences in the head every day, and sleep seems to be the way the brain deals with it all."
【小题1】The phrase" to sleep on a problem" in Paragraph 1 most likely means to______.
| A．pay full attention to a problem | B．wait until later for a decision |
| C．sleep to forget a problem | D．have difficulty sleeping |
| A．put together words of similar meanings |
| B．remember words and their meanings |
| C．show their knowledge of words |
| D．make up lists of related words |
| A．Themes learned right before the test |
| B．Rules from personal experience |
| C．Words learnt before a good sleep |
| D．Ideas stored together in the brain |
| A．It shows sleep may help us manage information |
| B．It helps find out the common themes of word |
| C．It tells us that more sleep can improve health |
| D．It proves the value of old-fashioned advice |

In general, people talk about two groups of colours warm colours and cool colours. Researchers in psychology think that there are also two groups of people people who prefer warm colours and people who prefer cool colours.
The warm colours are red, orange and yellow. Where there are warm colours and a lot of light, people usually want to be active. People think that red, for example, is exciting. Sociable people, those who like to be with others, like red. The cool colours are green, blue and violet. These colours, unlike warm colours , are relaxing. Where there are cool colours, people are usually quiet. People who like to spend time alone often prefer blue.
Red may be exciting, but one researcher says that time seems to pass more slowly in a room with warm colours than in a room with cool colours. He suggests that a warm colour, such as red or orange is a good colour for a living room or restaurant. People who are relaxing or eating do not want time to pass quickly. Cool colours are better for offices or factories if the people who are working there want time to pass quickly.
Researchers do not know why people think some colours are warm and other colours are cool. However, almost everyone agrees that red, orange, and yellow are warm and that green, blue and violet are cool. Perhaps warm colours remind people of warm days and the cool colours remind them of cool days. Because in the north the sun is higher during summer, the hot summer sunlight appears yellow.
【小题1】Which of the following colours belong to cool colours?
| A．Yellow, green. | B．Blue, violet. |
| C．Black, blue. | D．Brown, white. |
| A．Sociable people like warm colours. |
| B．Warm colours can make people excited. |
| C．People who like to be with others don’t like red. |
| D．Where there are warm colours, people want to be active. |
| A．Red or orange for offices. |
| B．Orange for dining-rooms. |
| C．Blue for bedrooms. |
| D．Red for studies. |
| A．It shows the reason why people think some colours are warm and others are cool. |
| B．Warm colours remind people of warm days. |
| C．Cool colours remind people of cool days. |
| D．People have an agreeable opinion of warm colours and cool colours. |

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated a small robotic wheelchair directed by a person's thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles.” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.
【小题1】BCI is a technology that can ________.
| A．help to update computer systems |
| B．link the human brain with computers |
| C．help the disabled to recover |
| D．control a person's thoughts |
| A．By controlling his muscles. |
| B．By talking to the machine. |
| C．By moving his hand. |
| D．By using his mind. |
| A．scalp→computer→cap→wheelchair |
| B．computer→cap→scalp→wheelchair |
| C．scalp→cap→computer→wheelchair |
| D．cap→computer→scalp→wheelchair |
| A．Switzerland, the BCI Research Center |
| B．New Findings About How the Human Brain Works |
| C．BCI Could Mean More Freedom for the Disabled |
| D．Robotic Vehicles Could Help to Cure Brain Injuries |
