Many businesses today use conferences as a means of discussing new plans of the company. As people are paying more attention to the environment and green problems, more businesses are looking for ways to reduce their negative effect on the environment. Many businesses do this by using web conferencing.
Web conferencing is a technology that allows people to communicate more effectively over the Internet. It is an easy way of hosting and attending conferences without having to leave the office. Each of the people involved in a web conference will be posted an invitation to the conference with the time and date of the Web conference on it. When the conference is ready to begin, all participants (参与者) must sit at their computers and they will be connected over the Internet.
With Web conferencing all participants attend the conference from the comfort of their own desk. Obviously, in doing this no fuel is used in traveling to and from a conference, and less work time is taken up in attending a conference.
Any material to be used during the Web conference is simply e-mailed to all the participants before the conference. Participants can then either choose to print material or read it on screen. This not only saves paper but also greatly reduces mailing cost for the business.
As a conference hall or business center isn’t being used, it means that the only power that is used is the power used by the participants’ personal computers. Similarly conference organizers don’t have to arrange for food or overnight accommodation (住宿) for participants of their conferences. All this means that less energy is used.
Often in business some companies actively choose to do business with other companies that do many things to reduce their negative impact on the environment. And Web conferencing helps you show other businesses that you are willing to work hard for the green cause.
So Web conferencing is much cheaper and greener and more people are willing to host and attend a web conference.

Can people change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour. 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 colour of a dark-striped zebra fish to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebra fish skin colour is determined by pigment cells, which contain melanosomes (黑色素体). The number, size and darkness of melanosomes per pigment cell determines skin colour.
It appears that, like the golden zebra fish, light-skinned Europeans also have a mutation (突变)in the gene for melanosome 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 zebra fish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun, 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 colours, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like chemical treatment done on Michael Jackson.

We know that sugary sodas aren’t good for our bodies. Now it turns out that they may not be good for our minds, either. A new study of more than 260,000 people has found a link between sweetened soft-drinks and depression, and diet sodas may be making matters worse.
Americans drink far more sodas than people in other countries— as much as 170 liters per person per year. But the impact of this study isn’t limited to the United States. “Sweetened drinks, coffee and tea are commonly consumed worldwide and have important physical consequences. And they may have important mental-health consequences as well,” study author Dr Honglei Chen said in a statement.
The study studied 263,925 people between the ages of 50 and 71. Researchers followed their consumption of drinks like soda, tea coffee, and other soft drinks from 1995 to 1996 and then. 10 years later, asked them if they had been diagnosed with depression since the year 2000. More than 11,3000 of them had.
Participants who drank more than four servings of sodas per day were 30 percent more likely to develop depression than participants who did not drink sodas at all. People who stuck with fruit punch(鸡尾酒), had a 38 percent higher risk than people who didn’t drink sweetened drinks. And all that extra sugar isn’t the actual problem. Researchers say that the artificial sweetener aspartame may be to blame.
The study found a link but could not surely determine whether sodas and other sweet soft drinks cause depression. Still, the results “are consistent with a small but growing body of evidence suggesting that artificially sweetened beverages may be linked to poor health outcomes.”
But there’s a bright side for those who can’t live without their daily sodas. Adults who drank coffee had a 10 percent lower risk of depression compared to people who didn’t drink any coffee, according to the study. “Our research suggests that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk,” said Chen.
【小题1】What has the new study of more than 260,000 people found?
| A．Sugary sodas aren’t good for the physical health of old people. |
| B．Americans have a special tooth for sweet foods. |
| C．Sweetened soft-drinks may increase the risk of depression. |
| D．Sweetened soft-drinks have important physical consequences. |
| A．About twenty-six thousand people participated in it. |
| B．The oldest participants were below 80 when the study was over. |
| C．Most of the participants had depression when the study was over. |
| D．The study lasted more than ten years from the beginning to the end. |
| A．can reduce the harm of sweetened drinks |
| B．is used to reduce the risk of depression |
| C．is mainly used to make fruit punch |
| D．is used to make something .sweet |
| A．more research is needed to confirm the new findings |
| B．the new findings aren’t consistent with any previous findings |
| C．cutting one’s sodas intake will surely reduce one’s depression |
| D．the new findings won’t have an impact on people’s drinking habits |
| A．Sodas. |
| B．Unsweetened coffee. |
| C．Sugary coffee. |
| D．Fruit punch. |

In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet (彗星). When the fragments (碎片) landed in the southern part of the giant planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet?
The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the Earth. The news has caused panic.
On 17 July, a fragment four kilometers wide enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.
Millions of people are already dead in the southern part of the Earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end?
【小题1】55.Which of the following is NOT TRUE according to the author's description of the disaster in 2094?
| A．The whole world becomes extremely cold |
| B．All the coastal cities in Africa are destroyed |
| C．The visit of the comet results in wars |
| D．The whole mankind becomes extinct |
| A．Because they could only live in the warm climate |
| B．Because their extinction indicates future disasters |
| C．Because they once dominated the earth |
| D．Because dinosaurs and humans never live in the same age |
| A．give an accurate description of the possible disaster in the future |
| B．prove that humans will sooner or later be destroyed |
| C．warn of a possible disaster in the future |
| D．tell the historical development of the Earth |
| A．article of popular science | B．news report |

Clothes can make phone calls, play music, dial your pal’s number, keep you warm during cold weather and operate your computer?
This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes—clothes that have minds of their own! Scientists, working for the company, have invented a kind of fabric that can be blended(混合) with flexible electronic materials to create intelligent clothing. The result are electronic garments.
If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-free, soft to touch and washable! Like any electronic device, these high-tech clothes have to be powered. Currently, a tiny nine-volt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. These clothes are 100 percent shock proof, they say.
The Electrotextiles team has also created the world’s first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These ‘lap-tap’ gadgets(器具) are all set to take over laptop computers!
Another useful garment is the shirt-cum-mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wear include the denim(牛仔布) jacket with flexible earphones sewn into the hood(风帽) and the electronic ski jacket with a built-in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids.
Having completed the cloth keyboard, scientists have already started to work on a new project—a necktie that can be used as a computer mouse. What is the next? Do you have any idea?
【小题1】The electronic garments are similar to other electronic devices in that _________.
| A．they feel smooth and soft | B．they use electricity as power |

The rat is named Lola and she’s at the top of her class of risk-running animals being trained to smell out landmines (地雷) in Colombia, home to the world’s highest number of mine-related deaths and injuries last year. Of the victims, many are children who died in the accidents while walking to school or playing in the countryside.
The smartest rat among the first six that the government is teaching to locate landmines equipment planted by rebels(叛乱者) has a 90 percent success rate in locating landmines material in her lab training.
Police animal trainers, tired of seeing their landmines-smelling dogs blown up by stepping on mines, hope the white-furred, pink-eyed creature will lead her classmates through coming open field tests and then into the country mine fields before the end of the year. It takes about 400 grams of pressure to detonate (引爆) a mine while Lola only weighs about 220 grams. “The dogs can easily set off the landmines, sometimes killing people nearby,” they said.
Police animal trainer Jose Pineda says that rats have more sensitive noses than dogs, which should allow them to better smell out mines in difficult terrain (地形).
Plus, it takes the police about six months to train mine-smelling dogs. Training the rats is expected to take about half that time once the program is established.
Trainers think that they are much smarter than the dogs. The second-best scorer in the laboratory is Lucrecia, with an 83 percent success rate. Males, such as one named Runcho, have fallen behind until now but may do better in the coming field tests. Pineda said that the next step of training will present new challenges to the rats as they are sure to meet distractions (分心的事) in the open.
【小题1】What do the underlined words “the accidents” in the first paragraph mean?
| A．Children were shot while playing outside. |
| B．A buried landmine was walked on and set off. |
| C．A rebel blew up a landmine and killed children. |
| D．Children got hurt in traffic accidents on the way to school. |
| A．They have a good sense of smell. |
| B．They are too light to set off buried landmines. |
| C．They can smell all kinds of explosive materials. |
| D．They cost people less time in terms of training |
| A．Rats will perform as well in the open air as in the lab. |
| B．Until now, female rats are better than the male ones. |
| C．Trainers should have chosen only female rats for the program. |
| D．Because they are foolish, dogs are not preferred for the program. |
| A．Dogs Bring Peace to the People in Colombia |
| B．Colombia Develops a New Way to Reduce Deaths |
| C．Buried Landmines are a Great Danger to Colombians |

In recent years，American students have fallen behind in many subjects like math，science and reading. In 2005，the U.S. was number nine among the developed countries in the number of students graduating from high school.
American education officials are searching for new ways to help students learn again. One tool that is getting some attention is the use of video games.
Sixteenyearold John Diaz says he loves playing video games but doesn't like traditional schoolwork. During his summer vacation，Diaz is continuing his studies at home. That is because his courses are available on his home computer.
Florida Virtual School's head master，Julie Young，says the school teaches students with the technology they most enjoy using in and out of school.“We have so many students who feel free in our school，” Young said, “They lose interest when they go to school. And we're very hopeful that Conspiracy Code will attract the learners to really get into the detail of learning.”
Conspiracy Code is a video game that teaches U.S. history. Students guide two heroes in a quest to stop a conspiracy to change the past. Along the way，students learn about events such as the Civil War，and report back to their teacher who is a spy ．
John Diaz says he enjoys American history now.“I like to do the game every day，” he said.

Finland (芬兰) is perhaps the most beautiful and mysterious country of Northern Europe. Two-thirds of its surface is covered with thick forests. Relative to its size, Finland has more lakes than any other country. The northern part of this country is inside the Arctic Circle, where almost no trees can grow because of its cold weather and the people use their deer of transport, clothing and food.
The Finnish history began in the Middle Ages. In about 1155, Finland was conquered (侵略) by its western neighbor Sweden (瑞典). After a period of rule by Denmark (丹麦) in the 14th century, the Swedes won back independence and power in 1523 under their brave king. During the Napoleonic (拿破仑的) Wars (1804-1818) Finland was passed finally from Sweden to Russia. The opportunity came in 1917, when the Russian Revolution brought foreign rule of Finland to an end. Shortly after Soviet Russia made peace with Germany, 1919 saw the founding of the Finnish Republic.
The years between the First and Second World Wars were years of progress and growing development. Finland is the fifth largest country in Europe, and despite a relatively small population of 5.2 million, the market potential is much greater. Finland has no coal or oil, and the nation’s wealth lies in the timber from its forests, which supplies material for paper and furniture making, and in the electric power from its water. Finland is an excellent gateway to trading with Russia and the Baltic States because of a long history of trading with these marks. Finland has also enjoyed a strong and long-Finland’s accession to the European Union in January 1995.
【小题1】From the passage, we learn that Finland _______.
| A．lies inside the Arctic Circle |
| B．lies east of Sweden |
| C．is next to the countries of northern Europe |
| D．is entirely covered with forests and lakes |
| A．Russia | B．Denmark | C．Sweden | D．foreign countries |
| A．coal and oil | B．forests and water | C．paper and furniture | D．timber and power industry |
| A．Fruits. | B．Wood. | C．Animals. | D．Money. |

Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed.
There are different kinds of pollutants, each of which comes from different sources. It is necessary to identify the source of pollution, in order to make a policy to eliminate them.
Different products, processes and activities of our industrialized world together form the major source of pollution. The forms of pollution can be mainly divided into three kinds—solid, liquid and gas.
These pollutions have greatly damaged our planet and continue to do so. In fact, pollution is threatening our existence. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even posed a great threat to man’s existence.
We must face the situation that exists and take action to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the public must receive the education about the danger of pollution and so on.
The earth is our home and we have the duty to take care of it for ourselves and our later generation. Fortunately, more and more people have realized these problems. Measures have been taken to deal with these situations by the government. Laws have been passed to stop pollution, I hope the problems will be solved in the near future and our home will become better and better.
