Different creatures have developed some pretty creative ways to get their rest and stay safe. The lizard（蜥蝎）likes to sleep at the far end of small branches hanging out over a pond or lake in the rain forest. If a snake tries to slither up the branch to eat it ,it will shake the branch and knock the lizard off ,and the lizard will fall safely into the water. Chameleons can change color to match their surroundings in order to hide even while sleeping.
Corillas（大猩猩）like to sleep high in the trees. They build a new bed every night, sometimes taking up to half an hour to pile branches ,twigs ,and leaves into a fortable bed .Birds also find it safe to sleep in the trees, but unless they have eggs or young chicks ,they don’t use a nest .They just lock their feet around a branch and hang on .A special tendon（腱）in their legs in automatically tight when they are at rest ,so they won’t let go and fall.
Dolphins live underwater ,but must e to the surface to breather .Scientists now believe that dolphins may sleep with only half their brain, while the other half stays awake to keep them safe and breathing. Seals also do this ,lying on their sides on the surface of the water with one flipper underwater paddling to keep their noses above the surface. Some ducks may also have this ability, and actually sleep with one eye closed and one eye open.

But I wonder about my Momma sometimes, and all the other Negro(blacks )mothers who got up at 6 a.m. to go to the white man’s house with sacks over their shoes because it was so wet and cold. I wonder how they made it .They worked very hard for the man, they made his breakfast and they scrubbed his floors and they took care of his babies. They didn’t have too much time for us.
I wonder about my Momma ,who walked out of a white woman’s clean house at midnight and came back to her own where the lights had been out for three months ,and the pipes were frozen and the wind came in through the
holes in the wall. She’d have to make deals with the rats: leave some food out for them so the wouldn’t bite the doors or the babies. The roaches （蟑螂）？Oh ,they were just like part of the family!

Britain is facing a sharp rise in its rat population as growing numbers of people leave fast food scraps in the street ,an environment group warned .Keep Britain Tidy said the rodents（啮齿动物）were stopping their traditional hunts underground and were roaming the streets ,tempted by discarded burgers ,pizzas and crisps. “The rat population is on the rise and soon it’ll be as mon to see a rodent on our street as it is to see a dog or a cat,” said group Director ,Sue Nelson. The practice of dumping fast food litter and scraps on the street rather than in the trash—with
young men the worst offenders—was behind the rise. According to the National Rodent Survey in xx, Britain’s rat population has grown by nearly one quarter since xx and is now estimated at 60 million ,two million more than the human population. On average a rat can give birth every 24—28 days and just a single pair of rats can produce a colony of 2,000 a year. Around 200 people a year get Weil’s Disease –an infection which can lead to liver or kidney（肝肾）failure and eventually death and which is arrived in rat’s waste. To highlight the issue ,Keep Britain Tidy launched a cinema ad entitled “How close do you want them to get?” The ad gave a shocking image of a young woman sleeping in a bed of rots –echoing the nightmare scene from James Herbert’s classic horror tale The Rats, in which mutant rodents begin to prey on（捕食）humans. 64．Where did the rodents use to search for food?

We all know what it is like to be unable to turn your head because of a cold in the muscles of your neck, or because an unexpected twist has made your neck ache and stiff. Your whole body feels tight. The slightest move makes you jump with pain. Nothing could be worse than a pain in the neck.
That is why we use phrase to describe some people who give you the same feeling. We have all met such people.
One is the man who always seems to be clapping his hands—often at the wrong time—during a performance in the theater. He keeps you from hearing the actors.
Even worse are those who can never arrive before the curtain goes up and play begins. They e hurrying down to your row of seats. You are fortably settled down, with your hat and heavy coat in your lap. You must stand up to ;et them pass. You are proud of your self—control after they have settled into their seats…Well, what now…Good God, one of them is up again. He forgot to go to the men’s room, and once more you have to stand up, hanging on to your hat and coat to let him pass. Now, that is “a pain in the neck.”
Another, well—known to us all, is the person sitting behind you in the movies. His mouth is full of popcorn; he is chewing loudly, or talking
between bites to friends next to him. None of them remain still. Up and down, back and forth, they go—for another bag of popcorn, or something to drink.
Then, there is the main sitting next to you at a lunch counter smoking a smelly cigar. He wants you to enjoy it too, and blows smoke across you food into your mouth.
We must not forget the man who es into a bus or subway car and sits down next to you, just as close as you will let him. You are reading the newspaper and he leans over and stretches his rock so that he can read the paper with you. He may even turn the paper to the next page before you are ready for it.
We also call such a person a “rubber neck,” always stretching his neck to where it does not belong, like neighbors who watch all your visitors. They enjoy invading your privacy. People have a strong dislike for rubbernecks. They hate being spied upon.

Babies are not just passing idle time when they stare goggle-eyed at the television—they are actually learning about the world, U.S. researchers said. Parents may want t limit what their babies see on television , based on the study, said Donna Mumme, assistant professor of psychology at Tufts University in Boston, who led the research. “Children as young as 12 months are making decisions based n the emotional(情感的)reactions of adults around them,” Mumme said in a statement. “It turns out they can also use emotional information they pick up from television. This means that adults might want to think twice before they speak in a loud and harsh voice or let a baby see television programs meant for information about the world. A mother urging her baby to eat some “yummy” soup on a brother crying in fear when a dog approaches can influence a baby’s reaction. Mumme’s team tested babies to determine. If television has the same influence, showing actors reacting on a videotape to objects such as red spiral letter holder, a blue humpy ball, and a yellow garden hose attachment. Babies aged 10 months or 12 months
were later given the same objects to play with. Ten-month-olds did not seem to e influenced by the video buy the 1-year-olds were. When the actors acted neutrally or positively to an object, the babies happily played with them. But if the actor had seemed afraid or disgusted, the babies would avoid the object.
72．Psychology is the study of .
A．human’s society and its growth
B．human’s hopes had dreams
C．human’s mind and behaviors
D．human’s languages and cultures
73．Which of the following is Mumme’s conclusion?

B．Adults need to think twice before they act in front of small babies.
C．TV programs provide small babies with all the information they need.
D．One-year-olds can be emotionally influenced by TV programs. 74．Mumme reached his conclusion by .
A．measuring the time babies spent in front of TV.
B．making TV programs and advertisements for kids.
C．showing actors how to react to blue bumpy balls
D．observing small babies’ reactions to TV programs
75．Which of the following may the study lead to according to the researchers?
A．Parents may want to limit what their babies see on television.
B．Actors may try to behave themselves well in front of babies.
C．Babies may be allowed to choose what they see on TV. D．Scientists may stop ignoring babies’ emotional world.
