More than two thirds of the world's polar bears will be wiped out by 2050，according to a shocking new study. By then，scientists say，global warming will have melted 42 percent of the Arctic sea ice. By 2100，only a very few of these important creatures will be left.
The report has been produced by the US Geological Survey. The scientists have publicized their findings in the hope of influencing US Interior Secretary Dirk Kempthorne，who has been asked to put polar bears on the US endangered species list.
Polar bears depend on floating sea ice as a platform for hunting seals，which are their main food. Without enough ice，polar bears would be forced to go onto the land，where they are poorly skilled hunters，and would be unlikely to adapt to the life on the land in time. Experts say few little bears would survive and the stress could make many females unable to get pregnant.
The team of American and Canadian scientists spent six months studying bears，on the ground，from spotter planes and in the lab，using computer models.
Some team members fear the result is even worse for the bears than what their report says. They say the Arctic is warming faster than anywhere in the world and much faster than their computer had been forecasting. Satellite observations have showed that the ice has decreased to an all－time low.
However，not everyone in the scientific community believes that global warming is happening on such an alarming scale. Another investigation has found that polar bears are still being hunted by wealthy “sportsmen” who want their skins and heads. At least ten international companies offer bear－hunting trips.What do we know about Dirk Kempthorne according to the passage?

| B．He is a protector of animals working for the US government. |
| C．He was asked to put polar bears on the US endangered species list. |
| D．He offered to put polar bears on the endangered species list. |

| A．Because polar bears can't catch enough food without ice. |
| B．Because polar bears eat ice when they feel thirsty. |
| C．Because polar bears will be easily found by hunters without ice. |

You might think I'd have little in common with a camel, but we do share one useful skill: both of us can go for a very long time without water. Usually I start my day with a cup of tea, and then I might have a glass of water with my lunch and one with dinner, that's about a liter of liquid in 24 hours. It feels like plenty, but apparently it's not nearly enough.
After years of suffering headaches and poor digestion I spoke to a neurologist about my regular headaches and a nutritionist about my poor digestion, and both told me I should be drinking up to three liters of liquid a day for my body to function at its best. I decided to conduct an experiment. What would happen if I drank the recommended amount every day for a month?
The photograph of me taken the day I started this trial demonstrates(展示）perfectly and rather frighteningly what a lack of hydration does to a face. I am 42, but have to admit I look more like 52 in this picture, which is shocking. There are dark shadows under and around my eyes, which make me look exhausted, a profusion of wrinkles and strange reddish blotches, and my skin lacks any luster（光泽）. It looks dead. Even my lips look shriveled（枯萎的）. This is all classic evidence of poor hydration, apparently.
Every system and function in our body depends on water. It flushes toxins from the vital organs, carries nutrients to cells, provides a moist environment for ear, nose and throat tissues, and eliminates waste.
Not drinking enough means all these functions becomes damaged. So I decided to see how I would look and feel if I drank three liters of water every day for 28 days. The results were astonishing.Which statement is Not True according to Paragraph 1?
| A．The author drinks about a liter of liquid every day. |
| B．The author has something in common with a camel. |
| C．The author thinks she drinks enough water every day. |
| D．The author actually has plenty of water in her daily life. |
Why did the author decide to drink the recommended amount of water?
| A．Because she was very fond of doing experiments. |
| B．Because she was informed of the importance of drinking enough water. |
| C．Because her doctors forced her to do it. |
| D．Because she wanted to be cured of her stomachache. |
The author’s lack of hydration caused the following physical responses Except_______.
| A．shriveled lips |
| B．enough luster of her skin |
| C．dark shadows around her eyes |
| D．wrinkles and blotches on her face |
According to the passage, the author most probably tends to tell us_________.
| A．the more water one drinks, the healthier he is |
| B．drinking water makes ladies look younger |
| C．drinking enough water is key to one’s health |
| D．it’s necessary to follow specialists instructions |
What will be probably written in the next paragraph?
| A．The author gave up the experiment. |
| B．The author had his health greatly improved. |
| C．The author suffered a lot from the experiment. |
| D．The author felt very disappointed at the result. |
Among various programs, TV talk shows have covered every inch of space on daytime television. But no two shows are more opposite in content, while at the same time standing out above the rest, than the Jerry Springer and Oprah Winfrey shows.
Jerry Springer could easily be considered the king of "rubbish talk". The show takes the ever-common talk show titles of love, sex, cheating, and hate, to a different level. Clearly, the Jerry Springer show is about the dark side of society, yet people are willing to eat up the troubles of other people's lives.
Like Jerry Springer, Oprah Winfrey takes the TV talk show to its top. But Oprah goes in the opposite direction. The show is mainly about the improvement of society and different quality of life. Contents are from teaching your children lessons, managing your work week, to getting to know your neighbors.
Compared to Oprah, the Jerry Springer show looks like poisonous waste being poured into society. Jerry ends every show with a "final word". He makes a small speech about the entire idea of the show. Hopefully, this is the part where most people will learn something very valuable.
Clean as it is, the Oprah show is not for everyone. The show's main audience are middle-class Americans. Most of the people have the time, money and ability to deal with life's tough problems. Jerry Springer, on the other hand, has more of a connection with the young adults of society. Compared with other TV talk shows, both the Jerry Springer and the Oprah Winfrey shows are _______.
| A．more interesting. | B．unusually popular. |
| C．more detailed. | D．more formal. |
Though the social problems Jerry Springer talks about appear unpleasant, people who watch the shows ________.
| A．show disbelief in them. | B．are ready to face up to them. |
| C．remain cold to them. | D．are willing to get away from them. |
Which of the following is likely to be a topic of the Oprah Winfrey show?
| A．A new type of robot. | B．National hatred (憎恨). |
| C．Family income planning. | D．Street accident. |
What is the advantage of the Jerry Springer show?
| A．The show exposes the dark sides of society. |
| B．The show pours poisonous waste into society. |
| C．Jerry sums up (总结) the whole idea of the show. |
| D．Jerry talks about the improvement of society. |
She is a cute, quiet girl. As a daughter, she has no secrets from her mother, who is very pleased with her. But recently she has become somewhat mysterious, not so open as before: what if she falls in love, which is too early for a girl of her age. After all, she is reaching the “dangerous stage”. These thoughts have caused trouble in the mother’s mind.
One weekend the girl came to tell her mother that she was going to the cinema with her schoolmates and would return late. This was the first time her mother had agreed, and she couldn’t help worrying because her daughter had never been away at night before. The mother waited till nine and her uneasiness(不安) got the upper hand over her. She decided to go out to meet her daughter. Just at that moment the noise of a car pulling up drew her to the window and ---there was her daughter, waving goodbye to a boy. Her heart missed a beat. When the girl came in, the mother was watching TV, pretending nothing had happened. “Mum, I’m back.” “Yeah.” “Sorry to be late. Still sitting up?” “Yes, Oh, that… Who’s that boy?” The daughter was stunned (发愣) for a moment. “Ah. It’s my monitor. He gave me a lift on his way home. Mum, I’m going to bed” “All right. Go to sleep early.”
Next morning, when the mother went to the daughter’s room to do some tidying, she found her diary left at her pillow. After a few minutes’ hesitation she finally opened it to the entry of the night before. It read: Mum, it was love that made you ask, but it would show your understanding of me if you hadn’t. Holding the diary, the mother fell in thought. Which of the following is TRUE according to the story?
| A．The girl knew her mother would ask her the questions about the boy. |

| B．thought her mother cared about her very much. |
| C．thought it was her mother’s duty to asked her. |

| C．Talk with their children about their early love. |
| D．Keep silent about their children’s privacy. |

If you plan on visiting to Fiji, you are probably looking for some fun things to do. Below are four unusual places.
The Poseidon Resort
The Poseidon resort is an underwater resort that gives visitors a beautiful view of sea life. This resort covers 255 acres. It’s covered and surrounded by a lagoon (咸水湖) that covers 5,000 acres and is about 90 feet under water, giving you a beautiful view of sea life right before your eyes. This resort even has a hotel for those who would prefer to have the unusual experience of sleeping and waking up to the beautiful scenery all around them.
The Sabeto Mud Pool
If you’re looking for something unusual to do, you can’t pass up the mud pool at Sabeto. It is located in a mountain range with a huge group of Geothermal (地热的) pools full of nice, warm mud. Getting down and into the mud in the pool is believed to have benefits for healthy skin. This is unusual, but adults and especially kids will love it.
Fire Walking
Fire walking in Fiji is believed to have originated on the island of Beau. Fire walking is when you walk on white-hot stones barefoot. To do this, you have to be mentally prepared for it. Trust me; there is a lot of preparation and strict rules that travelers follow in order to do this safely.
The Fiji Museum
The Fiji museum is unusual due to all the amazing artifacts you’ll see dating back 3,000-4,000 years. This museum has a certain attraction that makes it funny—a shoe. It’s been said that a man named Thomas Baker was eaten by the locals several centuries ago and the only thing left was his shoe. This unusual museum is a great idea if you bring the whole family to Fiji.Visitors who have the unusual experience of sleeping at the Poseidon resort can _________.
