阅读理解

For lots of animals—humans included—lazing about in the sunshine is one of life's greatest pleasures. But unfortunately, this leisure comes with a cost: sunburn. And, while its most likely victims are the fairer-skinned among us, animals are at risk of sunburn, too. But if this can happen to animals too, why, then, don't we ever see sunburned fish?

"If you think of it, the sun has been here forever in terms of our planet, and all individuals have been exposed to it," said Karina Acevedo-Whitehouse, a molecular epidemiologist from the Autonomous University of Queretaro, in Mexico. So, it's a pretty strong selective pressure that the sun has put on animals and that has led to many mechanisms of reacting to it."

Some of these mechanisms are obvious: hair, fur, wool, feathers and scales (鱼鳞) on many creatures create a barrier between sunshine and skin.

But, "marine mammals (海洋哺乳动物(, and specifically cetaceans (whales, dolphins and porpoises), are an exception because they don't have fur; they don't have scales," said Acevedo-Whitehouse, who has been studying sunburn in whales for over five years.

In skin samples taken from the backs of blue, sperm and fin whales on their cross-ocean migrations, Acevedo-Whitehouse and her colleagues discovered signs of sunburn from the whales' hours spent breathing and socializing at the surface. But crucially, they also discovered that whales have specialized mechanisms that help them cancel out this burn. "The common adaptation of cetaceans is that they appear to be very effective at repairing damage," she said.

Some whales generate colors that darken and protect their skin; others have genes (基因) that set off a protective stress response in the skin. There are even whales that have developed a hard, keratinized layer (角质层) that protects the delicate skin below. "We were excited to see there isn't really evidence of skin cancer in whales," Acevedo-Whitehouse said. Now, they're trying to understand precisely how those healing mechanisms work.

(1)、Which of the following problems is the text trying to solve?
A、Do whales ever get sunburnt? B、How do whales avoid sunburn? C、Do animals ever get sunburnt? D、How do mammals protect skin?
(2)、What does the "exception" in Paragraph 4 refer to?
A、Whales don't have fur to protect themselves. B、Whales can protect their skin even without fur. C、Whales build a wall between sunshine and skin. D、Whales' reacting mechanism is obviously found.
(3)、In what situation do some whales probably get sunburnt?
A、Breathing. B、Socializing above water. C、Sunbathing. D、Surfacing for a long time.
(4)、Some whales adapt well to sun damage, depending on ________.
A、rapid healing B、self-made sun cream C、protective coats D、impossibility of cancer

    It is quite reasonable to blame traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming horrible. Everybody knows that the nicest men would become fierce tigers behind the wheel. It is all right to have a tiger in a cage, but to have one in the driver's seat is another matter altogether.

    Road politeness is not only good manners, but good sense too. It takes the most cool-headed drivers great patience to give up the desire to beat back when forced to face rude driving.On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting. A friendly nod or a wave of thanks in answer to an act of politeness helps to create an atmosphere of good will and calm so necessary in modern traffic condition. But such behaviors of politeness are by no means enough. Many drivers nowadays don't even seem able to recognize politeness when they see it.

    However, misplaced politeness can also be dangerous. Typical examples are the driver who waves a child crossing the street at a wrong place into the path of oncoming cars that may be not able to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they want to. It always amazes me that the highways are not covered with the dead bodies of these grannies (奶奶).

    An experienced driver, whose manners are faultless, told me it would help if drivers learnt to correctly join in traffic stream without causing total blockages that give rise to unpleasant feelings. Unfortunately, modern drivers can't even learn to drive. Years ago, experts warned us that the fast increase of the car ownership would demand more give-and-take from all road users. It is high time for all of us to take this message to heart.

    Pastime is a bi-monthly magazine for curious young minds. Many of the topics we write about won't be covered in the classroom. All the articles are written in a lively style, and each one is paired with drawings by some of the country's most talented artists.

    History focuses on archaeological (考古的) sites around the world where archaeologists work to unearth important finds.

    World includes stories about daily life, folk tales, and history and traditions of the people and places.

    Sport includes nutrition tips, information about up-and-coming young athletes, and sports events.

    Art stimulates a child's cultural life, from film to theatre through to writing and music.

    On top of all that, Pastime is packed with items to stimulate a youngster's imagination, including pages of puzzles and a step-by-step guide to creating their own impressive-looking drawings.

    In every issue, we review the latest books top authors write for youngsters. There are also short works of fiction written especially for Pastime by some of our best writers.

    We know that children at this age are dealing with many emotions and sometimes difficult feelings, so we have a personal advice page to reply to questions dealing with personal and moral problems.

    Unlike many of today's throwaway comics, Pastime is written and designed to be kept and treasured. We know children love going online — but we also know how much they enjoy holding a printed magazine in their hands, and the excitement they get when each new issue drops through the letterbox personally addressed to them.

    Since many of you are planning to study at a college or university in the future, you may be curious to know what your future study will be like. This is the question I want to discuss with you today.

    First, let's talk about what your weekly timetable will look like. No matter what your major may be, you can expect to spend between four and six hours a week for each class attending lecture. Lectures are usually in very large rooms because some courses such as Introduction to Sociology or Economics often have as many as two or three hundred students, especially at large universities. In lectures, it's very important for you to take notes on what the professor says because the information in a lecture is often different from that in your textbooks. Also, you can expect to have exam questions based on the lectures. So it isn't enough to just read your textbooks; you have to attend lectures as well. In a typical week, you will also have a couple of hours of discussion for every class you take. The discussion part is a small group meeting usually with fewer than thirty students where you can ask questions about the lectures, the reading, and the homework. In large universities, graduate students called teaching assistants, usually direct discussion parts

    If your major is chemistry, or physics, or another science, you'll also have to spend several hours a week in the lab doing experiments. This means that science majors spend more time in the classroom than non-science majors do. On the other hand, people who major in subjects like literature or history usually have to read and write more than science majors do.

阅读短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。

    Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you'll hear people say that you can't expect someone else to love you until you love yourself. Either way, you've got to love yourself first and this can be tricky. Sure we all know that we're the apple of our parents' eyes, and that our Grandmas think we're great talents and our Uncle Roberts think that we will go to the Olympics. But sometimes it's a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge, it is time you should build a positive self-image and learn to love yourself.

    Self-image is your own mind's picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about US. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.

    The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don't allow doubts to occur in it.

    It very well might be that you are experiencing a negative self-image because you can't move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you're silly because you aren't good at math, find a tutor. If you think you're weak because you can't run a mile, get to the track and practice. If you think you're dull because you don't wear the latest trends, buy a few new clothes. But remember, just because you think it doesn't mean it's true.

    The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat (拍) yourself on the back, you'll know you're well on your way. Good luck!
