The color of animals is by no means a matter of chance; it depends on many considerations, but in the majority of cases tends to protect the animals from danger by making it less outstanding Perhaps, it may be said that if coloring is mainly protective, there ought to be fewer brightly colored animals. 1.. The kingfisher itself, though so brightly colored, is not easy to see.

2.. Thus, for instance, the lion, and the wild donkey are all sand—colored. “Indeed, in the desert, neither trees, brushwood, nor even undulation (起伏) of the surface afford the slightest protection to its enemies.3..” says an expert.

The next point is the color of the mature caterpillars(毛虫), some of which are brown. This probably makes the caterpillar even more outstanding among the green leaves. What would you do if you were a big caterpillar? Why, like most other defenceless creatures, you would feed by night, and lie hidden by day. 4.. When the morning light comes, they go down the stem of the food plant, and hide among dry sticks and leaves around the ground, and it is obvious that under such circumstances the brown color really becomes a protection. While we may say as　 a general rule that the large caterpillars feed by night and hide by day, it is by no means always the case that they are brown: some of them still remain green.5., and that the brown color is a later adaptation.

A. So do these caterpillars

B. Therefore, the color of the animals is bright

C. We can say that they formed a good habit

D. Desert animals are generally the color of the desert

E. We may conclude that the habit of hiding themselves by day comes first

F. However, there are some cases where vivid colors are themselves protective

G. So the color of birds, snakes and even smaller animals, is of one uniform sand color

Whale researchers believe they have found a new way to measure the amount of stress felt by whales when they experience serious threats, such as being hit by a ship, and they say the technique could help protect the huge sea creatures from dying off.

American Rosalind Rolland is the lead scientist on the project. She and her team are with the New England Aquarium in Boston, Massachusetts. They measured stress hormones (荷尔蒙 ) by studying baleen, a substance found in the upper part of the mouth of some kinds of whale. She explains that the baleen serves as a record that shows a spike in stress hormones when whales face dangers such as a changing climate and ship strikes. Scientists can then read these records, similar to reading the rings on a tree.

Understanding the information is important because whales who often feel stressed are less likely to be reproductive and more likely to become sick. That combination is not good for the whale population, which is already dangerously low.

The scientists did their work on a whale that had become trapped in fishing equipment, which some scientists estimate kills up to 300, 000 whales and dolphins annually. It was finally killed by Inuit hunters who found it trying to drag the fishing equipment. The hunters said the whale seemed to lack energy. When scientists examined the dead whale, they found its mouth showed an increase in stress hormones 20 times greater than normal.

Regina Asmutis-Silvia is a biologist with the Whale and Dolphin Conservation in Massachusetts. She didn’t participate in the research, but she says it is important. “We clearly understand that stress is bad for humans. We also need to understand that stress is bad for other animals, too,” she adds.

1.What does the text mainly tell us?

A.The dangers the whale often faces.

B.The measures to stop sea life being hit.

C.A discovery to measure stress on whales.

D.A way to protect the mouth of the whale.

2.Which of the following can best replace “spike” underlined in Paragraph 2?

A.Rise. B.Change. C.Crash. D.Slide.

3.What may a whale living a stressful life be like?

A.Calm and fierce. B.Unhealthy and unable to reproduce.

C.Uneasy and energetic. D.Sizeable and likely to lose appetite.

4.Why does the author mention the words by Regina?

A.To move on to another topic.

B.To stress the importance of the finding.

C.To tell the necessity of studying other animals.

D.To show the similarity between humans and animals.

Most people are aware of what the adoption process is because it has become rather common in our society. Adoption is where a child is legally placed with guardians (监护人) or parents (or perhaps a single parent) other than the birth mother or father. Once an adoption is finalized, all parental rights are turned over to the adoptive parents and there is no legal difference between adoptive parents and natural birth parents. There are generally two types of adoption, which are closed adoption and open adoption.

When an adopted person has access to his or her adoption file and original records, it is referred to as an open adoption. The term is also used to describe any contact that may be between the adoptive family, the birth parents, and the adopted child. The level of openness can change greatly in such contact depending on each individual relationship. There can be indirect contact between the natural birth parents and the child through the form of letters and photographs, or there can be actual physical contact.

A semi-open adoption is where the birth parents may have contact with the adoptive parents before the birth of the child, either once or several times. After the birth there is no more contact. A semi-open adoption may remain as it is or it can become either open or closed.

A closed adoption is where only the medical and historical information about the biological parents is given to the adoptive family. Typically, the birth and adoptive parents do not know each other’s identities. The record of the birth parents is kept sealed (密封). A closed adoption is usually only effective in the adoption of babies. The adoption of an older child who already knows his or her birth parents cannot be kept closed.

1.How many adoption types are mentioned in the passage?

A. 2.    B. 3.    C. 4.    D. 5.

2.Which of the following statements is TRUE about the closed adoption?

A. The birth parents may have indirect contact with the adoptive parents.

B. The biological parents may often go to see their birth child.

C. No information about the biological parents is given to the adoptive parents.

D. Generally speaking, the adoptive parents do not know the birth parents’ identities.

3.Suppose someone adopts a child and his biological parents often get contact with the child by telephone. We can call this adoption _____.

A. a closed adoption    B. an open adoption

C. a semi-open adoption    D. a semi-closed adoption

4.From the passage, we know adoption is _____.

A. where a child is brought up by the government

B. where a child is legally sent abroad by the birth parents

C. where a child is legally placed with adoptive parents

D. where a child is sent to live with the children whose parents have died

Imagine looking out of your window and seeing a whale swim by.That's the sight that surprises New York City residents recently.In the past years,humpback whales have been spotted in the two rivers surrounding the island of Manhattan,the Hudson River and the East River.1.

Experts say that river cleanup efforts have improved water quality and led to an increase in the number of fish there.Fish are on the humpback's menu.2.The sighting is also an encouraging sign that conservation efforts are helping humpback whales come back.In 1973,the species was listed as the endangered.Now scientists say humpback whales are making a comeback.

By the middle of the 20th century,hunting whales for profit had nearly wiped out many whale species.In 1973, the U.S. set up the Endangered Species Act.People were no longer allowed to hunt them in the U.S. waters.In 1982, the International Whaling is illegal worldwide.3.Last September,it was announced that nine groups of humpback whales are no longer endangered.Four groups are still endangered and a fifth is threatened.

4.The number of them is growing particularly faster in the Southern Hemisphere like Tasman Sea and Coral Sea.And the number of humpback whales in Hawaii has made an amazing recovery.In 1966,there were fewer than 1,500 humpbacks there.Today there are about 10,000.But humpbacks in other parts of the world are still struggling.

5.“We still have a lot of work to do,”says Angela Somma,head of NOAAS Fisheries’ endangered Species division.“But with the right protection,the number of humpback whales should continue to grow.

A.Those efforts to save whales are paying off.

B.People are frightened when seeing whales in the river.

C.Last year,one even swam past where the mayor lives.

D.Today there are about 100,000 humpback whales worldwide.

In the middle of the 20th century people were worried about whales.The number of whales killed worldwide came up to 66,000 per year.However,people weren't worried about the whale as an endangered animal.Instead,they were worried about the whale industry,which would disappear if there were no whales.In 1946,the International Whaling Commission was established.It limited the whale hunting for every country and controlled the whale industry.But the commission recognized that the limitation wasn't enough.They set a worldwide law against hunting whales with only two exceptions: the hunt for scientific research and "aboriginal whaling".Aboriginal whaling allows some countries to hunt a limited number of whales because it is a part of their culture.Some countries like Japan and Norway don't care about the law;they make excuses to hunt whales and sell the products.They only care about the money.

Many fishermen complain that dolphins,also a kind of whale,steal their fish.Therefore,they kill thousands of them.In fact,this is not the truth.In reality there are so many fishermen who steal the fish from each other.Some whale hunters say that they catch the animals for scientists.They have to research what whales are eating.For that, they kill them and look into their stomach.The truth is that they only want to sell the meat.Today scientists want to observe live whales for their research.

Many whale families are not protected and thousands of them are killed.Nobody knows if all whale families would survive,even if humans end all whale hunting today.The pollution of the oceans increases fast and the poison gets into the bodies of the animals.Many of them get sick and die.The human being has killed 90%-95% of many whale families.Others are already extinct.

Today some international organizations try to protect whales.They make reports to explain how important and endangered whales are.Now people are becoming more interested in whales and a complete new industry has developed,whale watching,which you may want to learn about.
