Polar bears are born in dens（洞穴）on land and their mother stays with them for the whole winter without eating anything．The mother and the babies emerge around March，famished from a long winter and must immediately go hunting to find food to stay alive．Now, the only hunting they know is to catch seals from floating ice in the open ocean．In March，polar bear mothers and cubs have to swim from the land in Spitsbergen to the edge of the polar ice cap．

      Normally this is a short swim，since in March the polar ice cap is very close to the land，and the polar bears，and even the babies，are good swimmers．However，last year we saw that the polar ice cap had really shrunk in size due to global warming

Swimming hundreds of miles，especially when they are hungry and have babies following them is really hard，and many bears are dying because of starvation．

The polar bear population in the Spitsbergen area was once threatened by hunters．In the 1970s，a ban on hunting was imposed and the polar bear population has been steadily increasing from just a few hundred to about 2，000 to 3，000．This was a great success story．However，now，because of global warming，the population is again in danger．If we do not stop making so much earbon dioxide。we will lose these beautiful animals forever．

The polar bears are just one example of animals that have become endangered because of man’s appetite for energy obtained by burning fossil fuels．All life on earth could be in danger unless we change our ways，What can we do? To reduce the amount of carbon dioxide in the air we must conserve and make energy without burning coal and oil．Instead，we can use the sun or the wind to generate electricity．We must also cut down on needless driving and turn things that use electricity off  when we are not using them．In addition，we have to stop cutting down forests and start planting more trees．

Most people hate change, which is sad since we often go through intense changes in life. And for some of us, even the smallest changes can upset our day. So the question is: Why do most of us find making adjustments to our lives so hard?
Fear of change is nothing new. Over a century ago, the Parisians were unhappy over a particular addition to their city: the Eiffel Tower. In fact, the citizens were so angry about the plans for the tower that they protested its construction. As strange as it may seem, their anger was completely natural. They were given no choice about the huge change that was going to be made, so they became angry.
But we get upset over changes even when we do have a say in the matter and think about them carefully. Changes are brought about every day by the decisions we make: which school to attend, which job to take, whom to marry. Voluntary changes also make most of us uneasy because we don’t know how those changes will affect our future.
People have discovered that the key to overcoming the fear and anger associated with change is to be flexible(可弯曲的). When they are flexible, people can adapt to new situations more easily. Being flexible is especially important in the 21st century as technology makes change occur faster than ever before. Those who oppose change, especially with technology in the workplace, may find themselves out of a job.
When change comes, and you have no choice but to face it, embrace it. A positive attitude helps a lot. In fact, the change may turn out to be the best thing for you. That new job you got may end up being much better than your old one. You may make the best friends of your life in the new city you moved to. Don’t merely focus on how you feel about change; instead decide to accept the change. The change is the reality, and it’s up to you whether the change will be a success or a failure. You never know – your next change may be your life’s Eiffel Tower!
【小题1】Why did the building of the Eiffel Tower make the Parisians unhappy?

Tobacco is the second major cause of death in the world. It is responsible for the death of one in ten adults worldwide (about 5 million deaths each year). If current smoking patterns continue, it will cause some 10 million deaths each year by 2020. Half the people that smoke today, that is about 650 million people, will eventually be killed by tobacco.
Tobacco is the fourth most common risk factor for disease worldwide. The economic costs of tobacco use are equally devastating (破坏性的). In addition to the high public health costs of treating tobacco-caused diseases, tobacco kills people at the height of their productivity, depriving (剥夺) families of breadwinners(养家糊口的人) and nations of a healthy workforce. Tobacco users are also less productive while they are alive due to increased sickness. A 1994 report estimated that the use of tobacco resulted in an annual global net loss of 200 thousand million US dollars, a third of this loss being in developing countries.
Tobacco and poverty are closely linked. Many studies have shown that in the poorest households in some low-income countries as much as 10% of total household expenditure is on tobacco. This means that these families have less money to spend on basic items such as food, education and health care. It contributes to a higher illiteracy rate, since money that could have been used for education is spent on tobacco instead.

What’s delicious to eat and comes in a variety of colors? Eggplant! And no, it has nothing to do with chickens! This strangely named vegetable is, however, as versatile as an egg．It can be steamed, fried, and baked．It can be eaten by itself or combined with meats and other vegetables．
Eggplant was first grown in India in the 5th century B．C．．Its popularity soon spread to China and then throughout Asia．Finally, during the Middle Ages the vegetable made its way to Europe．At that time, eggplant was not the shiny purple vegetable most people know today．Instead, it’s like a white egg．Due to this egg - like appearance, eggplant got its name．In its early days, the vegetable was so bitter that people often called it a “mad apple．” This nickname started because people believed its bitterness was bad for one' s health．People actually thought eggplant could cause madness and cancer．
Fortunately today people know that eggplant doesn't cause insanity or cancer．In fact eggplant is so healthy that it may prevent cancer．In addition, the brain and the heart benefit from this super vegetable．Since it's high in fibre, eggplant can improve digestion．
Italy, Turkey, Egypt, China and Japan are the leading growers of eggplant in the world today．Depending on its location, eggplant may be purple, green, orange or yellow - white．And it can be as small as a tomato or as large as a cucumber．Dish varieties range from simple to complex, with all of them being delicious．
Today, thousands of people gather in Loomis, Calif, for the annual Loomis Eggplant Festival．The main activity at the festival is eating delicious eggplant dishes．There is plenty more to do and see, though．Recipe contests, arts and crafts, performers, races and children's activities all “egg – cite” festival - goers．Most people at the festival would agree—eggplant is an “egg—cellent” vegetable．
