●Tower Bridge is one of London’s most well known landmarks. Opened in 1894, this hydraulic(液壓的)  bridge can be raised to permit river traffic to pass underneath.
Vistors to Tower Bridge can enjoy wonderful views of the River Thames from the bridge towers. There is also a museum which explain how the bascule bridge operates and discusses its history. Tower Bridge is often incorrectly referred to as London Bridge.London Bridge, however, is a different bridge that is located directly upstream from Tower Bridge.
●The British Museum is a “must do” for all visitors to London England. Treasures from around the world can be found in Britain’s largest and most popular museum. To top it off, admission to the British Museum is free of charge.
Due to the enormous size of the museums, visitors should priortize what they wish to see. One “must see” is the Rosetta Stone – a key puzzle piece in the recorded history of humankid. The british Museum is locted in the Bloomsbury district of London in London WC1.
●Greenwich Park is a beautiful large park located a few kilometers away from the centre of London. Attractions in Greenwich include the Cutty Sark, the Gypsy Moth and the Old Royal Observatory. A painted line at the obsevatory inicates zero degrees of longitude（經(jīng)度）.
Many visitors to Greenwich enjoy having their photos taken with one leg in the western hemisphere（半球）and the other in the eastern hemisphere. Greenwich is the place where time was officially tracked – “Greenwich Mean Time” or “GMT”.
Greenwich is located in London SE10.
●The Eurostar high – speed train service provides fast connections between London and Paris and London and Brussels. The Eurostar trains pass through the 32 – mile Channel Tunnel under the English Channel. The tunnel is also known as the “Euro Tunnel” or “Chunnel”. The Channel Tunnel is considered to be one of the world’s great engineering wonders.
Trains leave form the Waterloo Rail Station which is located in south London.

Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By sitting on exercise balls instead of chairs , teachers find students’ posture(姿勢) and attention improve.
Dottie Pownall, a fifth-grade teacher in West Virginia, USA, has been using balls as chairs since December 2008. “The students love them”, she says. Pownall took a survey(調(diào)查) of her students. She found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning.
The teacher, Pisa Witt, felt so strongly about the use of balls as chairs, she started Witt Fitt. This company encourages the use of the balls. And the company educates not only teachers but also students on how to use them. “Our products are used in 24 states, three provinces in Canada, Puerto Rico (波多黎各) and Japan,” says Witt, “ Research shows that sitting on the balls makes them sit up straighter（直的）. You can slouch(低頭垂肩地坐)on a ball,” says Witt, “but it feels bad.” Because the students are moving, their blood (血液) increases. That carries more oxygen( 氧氣) to the brain , so the kids have more energy and can pay attention longer.
“Besides, they’re fun.” says Pownall.
【小題1】What will happen if a student sits on a chair all day in school? The student will_________.

When we look at the sky and see a bright light moving quickly across it or coming towards the earth, we talk about seeing a “shooting star” or a “falling star”. These moving lights are not, in fact, stars at all. They are small pieces of matter from outer space, which burn up as they enter the Earth’s atmosphere. The correct name of them is meteoroids. Any pieces that make it to the Earth’s surface without completely burning up are known as meteorites. A meteor is actually the name given to the light we see when a meteoroid is burning up.
When a meteorite hits the Earth at speeds between 11 and 72 kilometers a second, it can do amazing damage. A very large meteorite could knock the earth out of its orbit. If this happened, all life on Earth would probably become extinct（滅絕）. The path we follow around the Sun would change and as a result the Earth would become either much hotter or much colder. This change in temperature would affect sea levels and the amount of water in rivers. There would either be huge floods, which would cover most of the land with water, or the oceans would dry up and there would be a drought, which means a long period of time without rain. Either way, nothing could survive. If a large meteorite landed in the sea it would almost certainly cause tsunamis, which would race towards the land, destroying everything in their paths.
Although it is unlikely the Earth will be struck by a meteorite large enough to do that kind of damage, there is evidence of fairly large meteorites hitting the Earth in the past. In 1908 a large area of forest in Tunguska, Siberia was destroyed by a meteorite that came apart just before it hit the ground. The moon, however, has about three billion craters隕石坑caused by meteorites impacting影響 its surface. The reason more meteorites have reached the surface of the moon than the surface of the Earth is that the moon does not have enough atmosphere for the meteorites to burn up in. some of the meteorites that have reached the Earth’s surface have done considerable damage. Some scientists believe it was a change of climate caused by meteorites hitting the Earth that resulted in the extinction of the dinosaurs and other large prehistoric animals.
Scientists are especially interested in meteorites because they contain information about the solar system. It is widely believed by scientists that most meteorites are produced by collisions（碰撞） between asteroids (small planets). These collisions probably happened many billions of years ago. This means the physical and chemical structure of a meteorite can give scientists information about the early days of the universe.
【小題1】The story is about ___.     

London: What could possibly he wrong with planting trees? The benefits are obvious: they firm the soil, absorb extra water and take carbon dioxide out of the atmosphere.
However, it now turns out that planting trees could add to global warming. Tree roots do a great job of keeping soil firmly on the ground and out of the wind's power. The problem is that some of those dust clouds play an important part in taking in carbon dioxide.
Huge dust storms blow out over the oceans from dry parts of North Africa and central Asia. Tons of dust are lifted and left as a thin film over the ocean surface.
Dust from China is carried east and left in the Pacific Ocean. If a tree-planting program there is successful and the dust supply reduced, the final result may be that less carbon dioxide gets locked away in the ocean.
Andy Ridgwell, an environmental scientist from the University of East Anglia, has spent the past few years studying dust and says his work shows clearly the complexity of the system and the importance of not working uselessly with it without understanding the results. For this reason the need is to focus on cutting carbon dioxide giving off rather than dealing with the land surface aimlessly.
An American scientist, Robert Jackson, has shown that when native grassland areas are occupied by trees, carbon is lost from the soil. "We are studying why the soil carbon disappears, but one theory is that trees do a lot more of their growing above ground compared to grasses, so less carbon goes directly into the soil from trees. " said Jackson.
In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to be outweighed by the loss of carbon from the soil below ground.
Countries that plan to combat global warming by planting trees may have to think again. Solutions to environmental problems are often more complex than they first appear, and understanding the Earth's climate is a very great challenge.

The speed and convenience of modern travel means that destinations that used to take a long time to travel to can now be reached quickly and easily. Even though” faraway” countries may now seem closer thanks to air travel, they may still be different from your home country. 【小題1】  Following are some fundamental rules that will make communication easier, and your trip more enjoyable.
【小題2】   If you don not know the word for something in local language, or can not make yourself understood verbally, try drawing a picture, or pointing to an object.
Avoid topics of conversation that you think may be sensitive. 【小題3】  .Feel free to show interest in the history and customs of the place you are visiting, but don’t ask too many questions about why things are done a certain way; you may offend the local people.
    【小題4】  Kissing on the street or in public places is unacceptable behavior and should be avoided. If you are unsure of how to behave, watch the local people and copy them---if they don’t behave in a certain way, you probably shouldn’t either.
Finally, if you are traveling on business, or plan to stay with a host to family, and you wish to take a gift, do some research.   【小題5】    . One of the easiest ways to offend somebody is to give the wrong gift.
Wherever you go in the world, always be tolerant of the local customs. Avoid being critical; try instead to show respect for the values of the country you are in, even if you do not necessarily agree with them
