A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.
In the past hundred years, humans have begun destroying rainforests in search of three major resources (资源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.
There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.
Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.

A new study shows one of the largest glaciers(冰川) in Greenland is becoming smaller and speeding to the sea faster than scientists expected. If it continues, Greenland itself could become much smaller during this century and global seas could rise as much as 3 feet.
The rates of change that we’re noticing are much higher than expected. If these rates continue, it is not likely that Greenland could shrink by several tens of percent this century. However, it’s not known how quickly this coastal response of the Greenland ice sheet melting will have an effect on the vast inland ice.
Greenland is the world’s largest island, covering area more than three times the size of Texas. Some 81 percent of it is covered by ice, and there are many glaciers. Glaciers are like slow-moving rivers of ice. Where a glacier meets the sea, its weight keeps it firmly resting on the bottom. A glacier’s front is the point where the water is deep enough that the glacier floats.
Since the 1970s, the front of Helheim stayed in the same place. Then it began melting rapidly, moving back 4.5 miles from 2001 through this past summer. It has also grown thinner, from top to bottom, by more than 130 feet since 2001. And over these past years, its trip to the sea has sped up from about 70 feet per day to nearly 110.
The melting is driven by a warmer climate. Temperatures in Greenland have risen more than five degrees Fahrenheit(华氏温度) in the last ten years. Since most of Greenland’s ice is on land, seas will rise as the ice melts. If all Greenland’s ice sheet melted, oceans would be 15-20 feet higher. Nobody expects that to happen any time soon.
【小题1】What can we know about the glaciers according to the passage?

A.Glaciers only lie in Greenland.
B.Water in glaciers is more than sea water.
C.Glaciers sometimes float on the water.
D.Glaciers can increase the water level of lakes.
【小题2】According to the passage, we know that Greenland ___________.
A.belongs to Canada
B.is the largest island in North America
C.is all covered with glaciers
D.is sinking under the sea level
【小题3】Which of the following may be the result of the disappearing of Greenland glaciers?
A.The climate of the world will be warmer.
B.The glaciers in other areas will be bigger.
C.It will be easy for explorers to visit the island.
D.Some coastal cities may be under the sea.

A new generation addiction is quickly spreading all over the world. Weboholism(醉心于网络), a twentieth century disease, affects people from different ages. They surf the net, use e-mail and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive habit. They cannot stop, and it affects their lives.
Ten years ago, no one thought that using computers could become compulsive(强迫性的)behavior that could affect the social and physical life of computer users. This obsessive behavior has affected teenagers and college students. They are likely to log on computers and spend long hours at different websites.
They become hooked on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don’t concentrate on homework, so this addiction influences their grades and success at schools. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.
They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual(虚拟的)life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.
Because of the change in their behavior, they begin to isolate(孤立 themselves from the society and live with their virtual friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confident with real live friends they have known all their life. It is a problem for the future. This addictive behavior is beginning to affect the whole world.
【小题1】The main idea of the passage is about _______.

A.the cause of weboholismB.the advantage of weboholism
C.the popularity of weboholismD.the influence of weboholism

A. “Better road design and training hold the key to cycle safety”, the new Transport Secretary said today as he pledged to restore Britain’s safety record. Patrick McLoughlin told Conservative Party Conference that while cycling was enjoying a post-Olympics boom, the number of casualties among cyclists was also rising. “But the number of accidents has gone up too. That means it needs better design and better education too.” Mr McLoughlin said in his first speech as Transport Secretary. 
B.  Cycling in the UK will become safer through “sheer weight of numbers,” the founder of one of the world’s leading cycle brands has said as he backed The Times’s Cyclesafe campaign. Simon Mottram, founder and chief executive of Rapha, has added his support to 40 cross-party MPs who have signed a letter urging David Cameron to use his speech at the Conservative Party Conference to promote measures to make the streets safer for cyclists.
C.  Commuters who cycle to work face an increased danger as the casualty toll during peak hours rose by 10 percent last year. The rate at which cyclists were killed or seriously injured rose sharply last year, official figures showed yesterday.
D.  In future decades, Londoners will look back on the way cyclists jostled with buses and lorries on major roads as an absurd anachronism. Some risks are unavoidable. But other risks survive only because we are too slow to embrace bold solutions. That is the message from designers who are proposing an ambitious plan to create cycle lanes suspended above London’s busiest streets. London is one of the most dangerous places in the world for cycling. “SkyCycle” would remedy that problem by attaching dedicated cycle paths to existing railway viaducts.
E.  Money should be apportioned from the funding for major transport projects, such as the new Forth Crossing, to create a pot of cash for cycling, campaigners have told MSPs. Cycle groups have given warning that not enough money is being put into routes and promotion. They want the Scottish government to take a percentage of the funding allocated to key national projects and create an “active transport” fund to be distributed gradually.
F.  We’d like you to tell us why you love cycling by sending a photo of yourself, a family member or friend with their bike and a note about why it is so brilliant. To take part, instagram your photo with the hashtag #ilovemybike or email it to us at ilovemybike@thetimes.co.uk. We’ll post the best pictures here ilovemybike.tumblr.com.
