题型：不详难度：来源：

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.
77. Which of the following are the ways for penguins to keep warm?
a. staying together in good social order
b. several layers as radiators
c. a special circulatory system                    d. waterproof feathers
e. sending blood to bare patches
f. always staying in the middle
A. a, b, c                    B. a, c, d                    C. b, c, e                    D. c, d, f
78. The insulation consists of _______ layers.
A. two                        B. three                      C. four                       D. five
79. The underlined "puff up" in the second paragraph can be replaced by ______.
A. breathe deeply         B. blow up                 C. hold tight               D. spread out
80. The passage mainly tells us ______.
A. how penguins stay warm in cold places       B. that penguins are a clever animal
C. how penguins keep their temperature          D. why penguins can live a safe life

Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut.” Joanna noted.
Tina and Mark noticed similar changes in their 14-year-old daughter. ”She used to cuddle up with me on the sofa and talk,” said Mark. “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which.”
Before age 11, children like to tell their parents what’s on their minds. “ In fact, parents are first on the list.” Said Michael Riera, author of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years.” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”
Parents who know what’s going on in their teenagers’ lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.
65．“The door to his room is always shut” suggests that the son________.
A．is always busy with his studies
B．doesn’t want to be disturbed
C．keeps himself away from his parents
D．begins to dislike his parents
66．What troubles Tina and Mark most is that_______
A．their daughter isn’t as lovely as before
B．they can’t read their daughter’s mind exactly
C．they don’t know what to say to their daughter
D．their daughter talks with them only when she needs help
67．Which of the following best explains ”the wall of silence” in the last paragraph?
A．Teenagers talk a lot with their friends.
B．Teenagers do not want to understand their parents.
C．Teenagers do not talk much with their parents.
D．Teenagers talk little about their own lives.
68．What can be learned from the passage?
A．Parents are unhappy with their growing children.
B．Parents have suitable ways to talk with their teenagers.
C．Parents should be patient with their silent teenagers.
D．Parent should try to understand their teenagers.

　　A train sped up through the countryside at 60 mph as a“traveller”relaxes with his newspaper. But this is no businessman taking it easy—the driver of the passenger express（快车）is doing the reading.
　　A Sunday Express reader caught this Virgin employee on film as the train sped through Derbyshire on its way to Plymouth from Newcastle.
　　Virgin，which has come under repeated criticism over their rail service, yesterday fired the driver after being shown the photograph. A spokesman said an inquiry（调查）was under way to make sure exactly what he was doing and why he appeared to have taken his eyes off the track ahead.
　　The picture comes in the week that the public inquiry into the Southall rail disaster, which claimed seven lives, heard that the driver at the centre of that case had earlier been spotted with his feet on the control button of his cab.
　　Larry Harrison，who worked for Great Western Trains，drove through two warning signals before crashing at 60 mph into a waiting train.
　　The reader who took this picture was standing on a bridge outside Chesterfield early one summer’s evening. He said，“I only realized what I’d got when I had the pictures developed. I couldn’t believe it.”
　　“As far as I could see，there was no one else in the cab with the drive，unless they were hiding, The person with the paper open was certainly sitting in the driver’s normal seat.”
　　The photographer works on the railways and does not want to be named，but he added，“I’ve seen many drivers with their feet on the control panel but I’ve never seen them reading papers like this. There is an automatic warning system and driver’s safety device which reminds him when he passes yellow and red signals. But you should never take your eyes off the track and rely only on sounds because you could have unexpected objects on the line or suddenly have speed limits given.”
