Polar bears depend on ice to hunt (猎取)for food in the Arctic Ocean. They climb up on the ice to look for seals and other animals. But scientists say sea ice is decreasing (减少)because of climate change. They say rising temperatures have reduced the area in which polar bears can hunt.
Recently, a number of studies found that future reductions of sea ice could result in a loss of many polar bears within fifty years. The studies found a direct link between sea ice in the Arctic Ocean and the health of polar bears. The scientists say the animals will disappear from the north coasts of Alaska and Russia in the next fifty years. The only polar bears to survive will be in Canada's far north and the west coast of Greenland.
The scientists found that almost two thirds of the world's nineteen polar bear populations will disappear from the earth by the middle of this century. The studies showed that three more groups of polar bears will disappear within seventy-five years.
Scientists say polar bears still can be saved. But they say the world must begin taking steps to reduce climate change to do this. The center for Biological Diversity says governments around the world need to reduce the release (释放)of pollution like C02 gas.
Scientists say one step toward this goal would be to include polar bears on America's list of endangered species. Then the government would be able to make sure that industrial activities do not threaten their survival. The United States Fish and Wildlife Service is expected to examine the new findings when it considers whether polar bears should be included on the Endangered Species List.

The need to feed a growing population is putting much pressure on the world's supply of water. With 97% of the world's water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage(短缺)seems strange to someone fortunate enough to live in a high rainfall country, many of the world's agricultural industries experience constant water shortages.
Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution(重新分配)are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys(山谷)are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.
This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers' overuse of irrigation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed.
Saudi Arabia's attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.What is most likely to be discussed in the paragraph that follows?
| A．Ways to reduce the costs of building dams. |
| B．Steps to improving water use management. |
| C．Measures to deal with worldwide water shortages. |
| D．Approaches to handling the pressure on water supply. |

When I was seven my father gave me a Timex, my first watch. I loved it, wore it for years, and haven’t had another one since it stopped ticking a decade ago. Why? Because I don’t need one. I have a mobile phone and I’m always near someone with an iPod or something like that. All these devices（装置）tell the time—which is why, if you look around, you’ll see lots of empty wrists; sales of watches to young adults have been going down since 2007.
But while the wise have realized that they don’t need them, others—apparently including some distinguished men of our time—are spending total fortunes on them. Brands such as Rolex, Patek Philippe and Breitling command shocking prices, up to £250.000 for a piece.
This is ridiculous. Expensive cars go faster than cheap cars. Expensive clothes hang better than cheap clothes. But these days all watches tell the time as well as all other watches. Expensive watches come with extra functions—but who needs them? How often do you dive to 300 metres into the sea or need to find your direction in the area around the South Pole? So why pay that much of five years’ school fees for watches that allow you to do these things?
If justice were done, the Swiss watch industry should have closed down when the Japanese discovered how to make accurate watches for a five-pound note. Instead the Swiss reinvented the watch, with the aid of millions of pounds’ worth of advertising, as a message about the man wearing it. Rolexes are for those who spend their weekends climbing icy mountains; a Patek Philippe is for one from a rich or noble family; a Breitling suggests you like to pilot planes across the world.
Watches are now classified as“investments”(投资). A 1994 Philippe recently sold for nearly £350, 000, while 1960s Rolexes have gone from £15, 000 to £30, 000 plus in a year. But a watch is not an investment. It's a toy for self-satisfaction, a matter of fashion. Prices may keep going up—they’ve been rising for 15 years. But when fashion moves on, the owner of that £350, 000 beauty will suddenly find his pride and joy is no more a good investment than my childhood Timex.
It seems ridiculous to the writer that_______________.
| A．people dive 300 metres into the sea |
| B．expensive clothes sell better than cheap ones |
| C．cheap cars don’t run as fast as expensive ones |
| D．expensive watches with unnecessary functions still sell |
What can be learnt about Swiss watch industry from the passage?
| A．It’s hard for the industry to beat its competitors. |
| B．It targets rich people as its potential customers. |
| C．It wastes a huge amount of money in advertising. |
| D．It’s easy for the industry to reinvent cheap watches. |
Which would be the best title for the passage?
| A．Watches? Not for Me! |
| B．My Childhood Timex |
| C．Timex or Rolex? |
| D．Watches—a Valuable Collection |
As soon as you meet, or even see, a person, you form an impression of him based on his posture, gesture and facial expressions. This is why it is important to make a good first impression on the person who will be interviewing you. Within the first 60 seconds of meeting you, the interviewer will have formed an impression about what type of person you are and what kind of employee you would become, and 55% of this will be based only on your body language. Here are some tips to make you that impression a good one.
First of all, relax. Think positive thoughts and you are more likely to come across as a positive, confident person during the interview. Dress smartly, as your appearance is one of the first things an interviewer will notice you. Stand up straight, and walk in with your shoulders back and your head up. Try to avoid slowing down as you walk into the room because this suggests fear and uncertainty. Shake hands with the interviewer firmly. You should have a positive handshake and a warm smile. Open your coat or jacket as you sit down shows that you, too, are open.
Posture is important. You should be sitting well back in your seat. Sit up straight and lean forward slightly, but not too much. Sitting at too much of an angel expresses discomfort and distrust. Two of the most common defensive(防卫的) signals are crossing your arms and legs, so try to avoid them.
Another important issue is eye contact. Looking someone in the eye shows confidence in yourself and trust in the other person. However, don’t overdo it, as too much eye contact or starring will make the other person uncomfortable. Use more eye contact when listening than when talking, and when you look away, look down. Looking up at the ceiling will make you seem bored and rude.The purpose of the first impression is to tell readers __________.
| A．what a good first impression is |
| B．how to make a good first impression |
| C．how long it takes to make a first impression |
| D．the importance of making a good first impression |

| A．Cross your arms or legs |
| B．Open your coat or jacket when sitting down |

If you lean forward too much, it means __________.
| A．you are very bored |
| B．you are too nervous |
| C．you don’t have confidence |
| D．you don’t trust others |
