How Do Animals Catch Their ZZZ’s?
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 (变色龙)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 comfortable 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 is automatically tight when they are at rest, so they won’t let go and fall.
Dolphins(海豚) live underwater, but must come to the surface to breathe. 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 (海豹) 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. (281 words)

Have you wondered why different animals or pests have their particular colors? Colors in them seem to be used mainly to protect themselves.
Birds, especially seagulls are very fond of locusts, but birds can’t easily catch locusts because locusts change their colors together with the change of the color of crops. When crops are green, locusts look green. But when crops are ripe, locusts take on exactly the same brown color as crops have. Some other pests with different colors from plants are usually easily found and eaten by their enemies. So they have to hide themselves in terror for lives and appear only at night.
If you study the animal life in any part of the world, you will find the main use of coloring is to protect themselves, bears, wolves and other beasts move quietly through forests. They are usually invisible to the eyes of hunters, because they have the color much like the barks(树皮) of trees.
An even more strange act remains to be noticed. A kind of fish living in seas can send out a kind of very black liquid when it faces danger. While the liquid is over, its enemies cannot find it, and it quickly swims away. Thus, it has existed up to now though it is not powerful at all.
1.This passage mainly talks about ______.
A. the change of color in locusts
B. the protective coloration of animals and pests
C. how a certain sea fish protects itself
D. animals or pests can dye themselves different colors
2.Locusts are ______ but they aren’t easily wiped out(消灭)by their enemies because _______.
A. animals; they are powerful enough
B. beasts; they are dangerous to their enemies
C. pests; they take on the same colors as crops
D. birds; they fly very fast
3.What does the underlined word “invisible” in Paragraph 3 mean?
A. can’t be seen B. can be seen C. can’t move D. can’t change

Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need.It has been demonstrated(证明)that rats will, when given a choice over a period of time, prefer water with vitamins(维生素) to water without vitamins even though there is no difference in taste or smell between the two water bottles.When a fragrant(香的)flavor(作料)was added to the vitamin-enriched water, the rats did seem to prefer it and kept drinking it ,even after the vitamins were switched to the clear water.In time, however, they broke the habit and went back to where the necessary vitamins were.
In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria(自助) feeding arrangement, with a wide selection of baby food before them.They were given whatever food they pointed to or appeared interested in.We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet.
So, in choosing food, rats and babies do seem to know and act on what's best for them.Apparently, there is a kind of “body wisdom”, which humans soon lose.Most of us do not eat as wisely as we could.Many of our food preferences are culturally determined and influenced by long-formed habits.Some people eat fox, dog and blackbirds, while we eat cows and pigs.So what people eat and how much they eat seems to be greatly influenced by what is going on around them.
1.In the experiment on rats, a fragrant flavor was added to the rats’ drinking water to _____________ .
A.encourage rats to drink vitamins-enriched water
B.test whether rats know which drink is good for them
C.find out rats’ preference in flavor
D.demonstrate the vitamins are tasteless
2.According to the passage ,adults eating habits differ from those of babies because_________.
A.adults know better than babies what kind of food are good for their health
B.adults usually cannot resist the temptation of various delicious foods
C.adults have more choices of food than babies in eating patterns
D.adults' eating habits are closely related to the social and cultural customs
3.The author implied in the passage that most of us_________.
A.eat a balanced diet
B.choose the food that is of nutrition
C.have the habits influenced by the surroundings
D.like to eat the food with a fragrant flavor.
4.As far as their eating habits are concerned, babies and rats are similar in that_________.
A.both prefer flavored food and drink
B.both have the wisdom to choose a balanced diet
C.both have the same eating patterns
D.both develop a taste for the same kinds of flavors

Scientists think they have answered a mystery: How some ocean creatures got so huge so quickly.
A few million years ago, the largest whales, averaged about 15 feet long. Then seemingly overnight, one type of whale, the toothless baleen whale(须鲸类)became huge. Modern blue whales get as big as 100 feet. Nicholas Pyenson of the Smithsonian Natural History Museum said, “Why is that?” ”It happened in the glance of an evolutionary eye, which makes it harder to figure out what happened,” said Graham Slater, lead author of the study. Their study has suggested an answer: Ice ages in the last 3 to 5 million years started it, changing the oceans and food supply for whales.
The researchers used fossil records of the smaller whales to create a family tree for baleen whales which include blue whales, humpbacks and right whales. Using computer simulations(模拟)and knowledge about how evolution works, they concluded that when the size changes started, the poles got colder, ice expanded and the water circulation in the oceans changed and winds shifted, Slater and Pyenson said cold water went deep and moved closer to the equator(赤道)and then eventually moved back up with small fish and other small animals that whales eat.
Baleen whale, which have no teeth, feed by eating huge amounts of fish they capture. Toothed whales, like sperm whales (抹香鲸), hunt individual fish, so the ocean chants that made food less evenly spread out didn’t affect them as much. But baleen whales hunt schools of fish.
Olivier Lambert at the Royal Belgian Institute of Natural Sciences calls it “a really convincing situation”. But he said the lack of fossils in certain time periods is an issue. As oceans warm from man-made climate change, the seas will be more like it was when the whales smaller and they will have a more difficult time surviving.
1.What does the author mean by “It happened in the glance of an evolutionary eye” in the second paragraph?
A. The change of baleen whales happened too quickly.
B. The change of baleen whales was too difficult to explore.
C. Researchers paid little attention to the change of baleen whales.
D. Researchers thought the change of baleen whales was unimportant.
2.What played the key role in baleen whales’ becoming huge?
A. Man-made climate change.
B. Its eating a huge amount of fish.
C. The water circulation in the oceans.
D. The increase of food supply for whales.
3.What do we know about sperm whales and blue whales according to the text?
A. Sperm whales eat more food.
B. Blue whaler live much longer.
C. Sperm whales prefer to hunt schools of fish.
D. Blue whales usually swallow schools of fish.
4.What can we infer from the last paragraph?
A. There are no whale fossils now.
B. The whales may become even bigger.
C. Global warming has threatened the whales.
D. Olivier Lamber thinks the study is perfect.
