All penguins (企鹅) swim in cold waters and so need a good layer of insulation (隔离), some species come ashore in hot places.Humboldt penguins,for example,nest in arid hot - 40°C, deserts on the west coast of South America, while others survive the lowest temperatures of any animals.Male Emperor penguins,as we know, spend the Antarctic winters incubating eggs in temperatures that can fall below -70°C. The insulation is provided in layers, under the skin is a thick layer of fat, then there is a layer of downy feathers that trap air, and finally another layer of waterproof feathers that keep the cold water away from the skin. With all this insulation penguins have no problem keeping warm at temperatures down to about -10°C - although they have special adaptations of the circulatory system to keep their feet from freezing and to prevent much heat loss through the feet that are on the ice. At lower temperatures penguins have to huddle (蜷缩) together to keep warm. In such huddles the penguins gradually move from the hot interior to the cold outside so that every penguin has his turn in the middle and on the outside.
In hot climates, penguins suffer greatly from overheating. They use several strategies to lose heat. They puff up their feathers so that air can circulate to their skin; they hold their flippers（脚蹼）out from their bodies and pump hot blood to them so that they can act as radiators; they open their mouths and breathe to lose heat from their hot breath; and those species that live in hot climates also have several bare patches of skin around the eyes and feet, they send blood to these bare patches when they are hot - you can recognize a hot penguin since it will have pink eye patches and pink patches on its feet.

In the middle of the Atlantic Ocean and preparing for the worst, Australian adventurer Peter Seiter wrote a farewell note to his family, put it in a bottle and threw it overboard. With a sense of bad feeling he wrote: “The ocean has a personality of its own. The place can be such a peaceful environment to be in, yet it can be frightfully violent. I’ve experienced both.” Fearing he wouldn’t make it home, he placed the note -- dated June 11, 1998 -- in a wine bottle and covered the bottle.
“I included my geographical coordinates, so if anything happened to me, they’d know my last place when I threw the bottle into the ocean,” says Peter, who was then sailing from the Azores in Portugal to New York and knew the Atlantic could be dangerous. He also included some money with his message, asking whoever found it to use the money to post the letter to his family.
Seventeen days later he reached his destination, having survived the dangerous seas, but he assumed his message in the bottle had not -- until it was found on shore, 11 years later!
Recently, American woman Katherine Ginn and her friend came across the bottle on a deserted beach in the Bahamas. “Alongside it they’d found a life jacket and, assuming the worst, opened the bottle and spent 24 hours drying it out so they could read my story and write to my family as I requested,” says Peter, 44. “I couldn’t believe it -- that after all these years my bottle had turned up with its contents, still undamaged.”
Overjoyed, he wrote to the pair, saying he was alive and living in Australia with his family.
Katherine posted him his letter, money and some broken glass of his bottle placed in a tiny box as a special souvenir. These special items now share pride of place among photos of Peter’s Atlantic voyage. “I can’t express what this old letter means to me,” Peter says. “It gives me a sense of hope and belief. It’s something special to share with my children as they grow up.” Why did Peter have the idea of a message bottle?
| A．He missed his family very much then. |
| B．He hoped to share his experience with his family. |
| C．He regretted taking a risk on the ocean. |
| D．He thought he might lose his life on the voyage. |
As for the survival of the message bottle, Peter ________.
| A．felt very certain about it |
| B．thought it had little chance of reaching land |
| C．took a long time to search for it |
| D．wrote a letter to Katherine |
What can be inferred about the message bottle according to Paragraph 3 and 4?
| A．Katherine found it by chance on a crowded beach. |
| B．It was 11 years before they came across it at sea. |
| C．Perhaps there was water in it when Katherine found it. |
| D．Peter couldn’t believe more that it was not damaged. |
From the passage, we can learn that ________.
| A．this was Peter’s first voyage in the Atlantic |
| B．Peter spent eleven days in the Atlantic |
| C．without the life jacket, the bottle wouldn’t have survived |
| D．Katherine was a caring and careful person |
What should you think about when trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow rules and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular career you see from the inside in a part-time job.
Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a number of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic(认错的) about it but instead recognize that you will have a chance of a fresh start at work.What is the passage mainly about?
| A．The importance of working hard at school. |
| B．Choosing a career according to one’s strengths. |
| C．How to face one’s weakness. |
| D．The value of school work. |

| D．a waste of time he could have spent on study |
From the passage we learn that if a student’s school performance is not good, he _________.
| A．should pay more attention to learning skills and developing abilities |
| B．will be regretful about his bad results |
| C．may also do well in his future work |
| D．should restart his study in school |
The underlined phrase “be all thumbs” (in para. 3) probably means “_______”.
| A．be not good at doing things |
| B．be skillful in doing things |
| C．be not interested in certain things |

The spread of Western eating habits around the world is bad for human health and the environment. These findings come from a new report in the journal Nature.
David Tillman, a professor of ecology at the University of Minnesota, America, examined information from 100 countries to identify what people ate and how diet affected health. He noted a movement beginning in the 1960s. He found that as nations industrialized, population increased and earnings rose, more people began to adopt(采纳) what has been called the Western diet.
The Western diet is high in sugar, fat, oil and meat. By eating these foods, people began to get fatter and sicker. David Tillman says overweight people are at greater risk for non-infectious diseases like diabetes（糖尿病）and heart disease.
Unfortunately when people become industrialized, if they adopt this Western diet, they are going to have these health problems, especially in developing countries in Asia. China is an example where the number of diabetes cases has been jumping from less than one percent to 10 percent of the population as they began to industrialize over a 20-year period. And that is happening all across the world, in Mexico, in Nigeria and so on.
And, a diet bad for human beings, is also bad for the environment. As the world's population grows, more forests and tropical（热带的）areas will become farmland for crops or grasslands for cattle. We are likely to have more greenhouse gas in the future from agriculture than that coming out of all forms of transportation right now.
Mr. Tillman calls the link between diet, the environment and human health, "a trilemma": a problem offering a difficult choice. He says one possible settlement is leaving the Western diet behind.According to the passage, more greenhouse gas might be given off in the future from ____________.
| A．transportation | B．developing countries |
| C．agriculture | D．developed countries |
David Tilman believes that__________.
| A．diet, the environment and human health are closely connected |
| B．the Western diet is the only choice as the nation industrializes |
| C．people in tropical areas are more likely to have heart disease |
| D．traditional diets are more balanced than the Western diet |
We can infer from the passage that ___________.
| A．Nigeria has the largest number of diabetes cases |
| B．overweight people are at higher risk of infectious diseases |
| C．the examined information comes from developing countries |
| D．industrialization contributes to the spread of the Western diet |
The main purpose of the passage is to___________.
| A．call on us to protect the environment |
| B．warn us of the danger of the Western diet |
| C．remind us of the importance of health |
| D．advise us to have a balanced diet |

Raised in a motherless home, my father was extremely tightfisted towards us children. His attitude didn’t soften as I grew into adulthood and went to college. I had to ride the bus whenever I came home. Though the bus stopped about two miles from home, Dad never met me, even in severe weather. If I grumbled, he’d say in his loudest father-voice, “That’s what your legs are for!”
The walk didn’t bother me as much as the fear of walking alone along the highway and country roads. I also felt less than valued that my father didn’t seem concerned about my safety. But that feeling was gone one spring evening.
It had been a particularly difficult week at college after long hours in labs. I longed for home. When the bus reached the stop, I stepped off and dragged my suitcase to begin the long journey home.
A row of hedge（树篱）edged the driveway that climbed the hill to our house. Once I had turned off the highway to start the last part of my journey, I always had a sense of relief to see the hedge because it meant that I was almost home. On that particular evening, the hedge had just come into view when I saw something gray moving along the top of the hedge, moving toward the house. Upon closer observation, I realized it was the top of my father’s head. Then I knew, each time I’d come home, he had stood behind the hedge, watching, until he knew I had arrived safely. I swallowed hard against the tears. He did care, after all.
On later visits, that spot of gray became my watchtower. I could hardly wait until I was close enough to watch for its secret movement above the greenery. Upon reaching home, I would find my father sitting innocently(天真地) in his chair. “So! My son, it’s you!” he’d say, his face lengthening into pretended surprise.
I replied, “Yes, Dad, it’s me. I’m home.”What does the underlined word “grumbled” in Paragraph 1 probably mean?
| A．Accepted happily. | B．Explained clearly. |
| C．Agreed willingly. | D．Spoke unhappily. |
What made the author feel upset was ______.
| A．the tiredness after long hours in labs |
| B．the fear of seeing something moving |
| C．the feeling of being less than valued |
| D．the loneliness of riding the bus home |
The author’s father watched behind the hedge because ______.
| A．he was concerned about his son’s safety |
| B．he wanted to help his son build up courage |
| C．he didn’t want to meet his son at the doorway |
| D．he didn’t think his son was old enough to walk alone |
Which of the following can be the best title for the text?
| A．My Father’s Secret. | B．My College Life. |
| C．Terrible Journey Home. | D．Riding Bus Alone. |
