2 . Now, let’s talk about earthquakes on our planet. Some countries have large numbers of earthquakes. Japan is one of them. Others do not have many. For example, there are few earthquakes in Britain. There is often a great noise during an earthquake. The ground vibrates (震动). Houses fall down. Trains run off the lines. Sometimes, there is a heavy loss of human lives.
Earthquakes often happen near volcanoes, but this is not always true. The centers of some earthquakes are under the sea. The bottom of the sea suddenly moves. The powerful forces inside the earth break the rocks. The coast is shaken and great waves appear. These waves, also known as seismic waves(地震波), or tsunamis(海啸) can travel long distances and rush over the land when they reach it. They are strong enough to break down houses and other buildings. Very often fires follow the most serious earthquakes. In 1906, the numbers of fires were burning in the city. The water pipes were also shaken and broken, so it was not possible to put the fire out. There was no water. The Tokyo Earthquake of 1923 happened just before noon. People were cooking meals on their fires at that time. When the ground shook, the fires shook, too. Hot materials were thrown on the different parts of the houses, some of which were made of wood. Soon 134 fires were burning in the city.
What kind of building stands up best in an earthquake? A building with concrete walls is perhaps the best. A steel frame will make it even stronger. The frame holds the different parts together and the walls so not easily fall. There is less chance of fire because concrete and steel do not burn. Over the years, scientists studied the results of the earthquake in different parts of the world, and they are convinced that this kind of building is the safest.

Polar bear poaching has been banned in Russia for more than 60 years. Still, it has been estimated that as many as 200 of them are killed each year. In February, local reports estimated that about 50 polar bears had taken over Novaya Zemlya, popping up in buildings, on playgrounds. As a result, officials declared a state of emergency, many people were too scared to leave their homes or let their children play outside, and

5 . There has, in recent years, been an outpouring of information about the impact of buildings on the natural environment. Information which explains and promotes green and sustainable construction design, strives to convince others of its efficacy (功效) and warns of the dangers of ignoring the issue. Seldom do these documents offer any advice to practitioners, such as those designing mechanical and electrical systems for a building, on how to use this knowledge on a practical level.
Although there are a good many advocates of “green” construction in the architectural industry, able to list enough reasons why buildings should be designed in a sustainable way, not to mention plenty of architectural firms with experience in green design, this is not enough to make green construction come into being. The driving force behind whether a building is constructed with minimal environmental impact lies with the owner of the building; that is, the person financing the project. If the owner considers green design unimportant, or of secondary importance, then more than likely, it will not be factored into the design.
The commissioning (委任) process plays a key role in ensuring the owner gets the building he wants, in terms of design, costs and risk. At the predesign stage, the owner’s objectives and expectations are discussed and documented. This gives a design team a solid foundation on which they can build their ideas. Owners who skip the commissioning process, or fail to take “green” issues into account when doing so, often come a cropper once their building is up and running. Materials and equipment are installed as planned, and, at first glance, appear to fulfil their purpose adequately. However, in time, the owner realizes that operational and maintenance costs are higher than necessary, and that the occupants are dissatisfied with the results. These factors in turn lead to higher ownership costs as well as increased environmental impact.
In some cases, an owner may be aware of the latest trends in sustainable building design. However, firms should not take it as read that the client already has an idea of how green he intends the structure to be. Indeed, this initial interaction between owner and firm is the ideal time for a designer to outline and promote the ways that green design can meet the client’s objectives, thus turning a project originally not destined for green design into a potential candidate.
Typically, when considering whether or not to adopt a green approach, an owner will ask about additional costs or return for investment. In a typical project, landscape architects, mechanical and electrical engineers do not become involved until a much later stage. However, in green design, they must be involved from the outset, since green design demands interaction between these disciplines. This increased cooperation clearly requires additional cost. However, there may be financial advantage for the client in choosing a greener design. There are examples of green designs which have demonstrated lower costs for long-term operation, ownership and even construction.

World Migratory Bird Day is an annual awareness-raising campaign highlighting the need for the conservation of migratory birds and their habitats. It has a global outreach and is an effective tool to help raise global awareness of the threats
Every year people around the world take action and organize public events such as bird festivals, education programmes, exhibitions and bird-watching
The theme of this year’s World Migratory Bird Day is “Birds Connect Our World”, which highlights the importance of conserving and

Killer Rabbits
You’d never think of rabbits as dreadful, destructive creatures, would you? Rabbits are cute and love-able. However, Australians discovered
Rabbits were introduced to Australia in 1788 as food animals. By 1827, they were running around large estates, and in 1859, disaster struck. A man released 12 wild rabbits onto his property for hunting and he
Six hundred million hungry rabbits could do real harm. They caused more damage than any other species introduced to the continent. They ate native plant species
The rabbits did some good, of course. They provided food for poor families. They supported fur industries. But their impact on the environment and major livestock economy was too negative

Many people know that trash is a big problem on planet Earth. What many people don’t know is that trash has become a problem in outer space too.
Statistically, there are more than 22,000 pieces of junk in space around the earth. And these are just the items that we can see from the surface of the earth by telescopes or radars.
Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to people, particularly astronauts. If the tiniest piece of junk crashed into a spacecraft, it could damage the vehicle. That’s because the faster an object moves, the greater the impact if the object collides with something else.
To help minimize additional space junk, countries around the world have agreed to limit the time their space tools stay in orbit to 25 years. Each tool must be built to fall safely into the earth’s atmosphere, or the mass of gases that surround the earth, after that.
Many scientists are also proposing different ways to clean up space junk. The Germans have been planning a space mission with robots that would collect pieces of space trash and bring them back to Earth so that they can be safely destroyed.
"In our opinion the problem is very challenging, and it's quite urgent as well," said Marco Castronuovo, an Italian Space Agency researcher who is working to solve the problem.
"The time to act is now; as we go farther in time we will need to remove more and more fragments," he says.
A.One reason that it’s urgent is that countries are sending more and more objects into space. |
B.There are also millions of smaller pieces of junk that we can’t see. |
C.Blowing up older satellites with a missile may create thousands of smaller pieces! |
D.In the upper parts of the atmosphere, it will burn up. |
E.When two objects in space collide, the two objects break into many smaller pieces. |
F.Years of space exploration have left tons of “space junk” in orbit around the planet. |
