Have you ever wondered why birds sing? Maybe you thought that they were just happy.After all,you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy.However,they sing most of the time for a very different reason.Their singing is actually a warning to other birds to stay out of their territory
Do you know what a “territory” is? A territory is an area that an animal,usually the male,claims(聲稱)as its own.Only he and his family are welcome there.No other families 0f the same species(物種)are welcome.Your yard and house are your territory where only your family and friends are welcome.If a stranger should enter your territory and threaten you,you might shout.Probably this would be enough to frighten him away.
If so,you have actually scared the stranger away without having to fight him.A bird does the same thing。But he expects an outsider almost any time,especially at nesting(筑巢) season.So he is screaming all the time,whether he can see an outsider or not This screaming is what we call a bird’s song,and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.
You can see that birds have a language all their own.Most of it has to do with attracting mates and setting up territories.
小題1:Some scientists believe that most of the time birds’ singing is actually.
A.a(chǎn)n expression of happiness
B.a(chǎn) way of greeting
C.a(chǎn)n expression of anger
D.a(chǎn) way of warning
小題2:What is a bird’s “territory”?
A.A place where families of other species are not accepted.
B.An area which a bird considers to be its own
C.a(chǎn)n area for which birds fight against each other.
D.A place where a bird may shout at the top of its Voice.
小題3:Why do birds keep on singing at nesting season?
A.Because they want to invite more friends
B.Because their singing helps get rid of their fears.
C.Because they want to find outsiders around.
D.Because their singing helps frighten outsiders away.

小題1:D

A new study shows one of the largest glaciers(冰川) in Greenland is becoming smaller and speeding to the sea faster than scientists expected. If it continues, Greenland itself could become much smaller during this century and global seas could rise as much as 3 feet.
The rates of change that we’re noticing are much higher than expected. If these rates continue, it is not likely that Greenland could shrink by several tens of percent this century. However, it’s not known how quickly this coastal response of the Greenland ice sheet melting will have an effect on the vast inland ice.
Greenland is the world’s largest island, covering area more than three times the size of Texas. Some 81 percent of it is covered by ice, and there are many glaciers. Glaciers are like slow-moving rivers of ice. Where a glacier meets the sea, its weight keeps it firmly resting on the bottom. A glacier’s front is the point where the water is deep enough that the glacier floats.
Since the 1970s, the front of Helheim stayed in the same place. Then it began melting rapidly, moving back 4.5 miles from 2001 through this past summer. It has also grown thinner, from top to bottom, by more than 130 feet since 2001. And over these past years, its trip to the sea has sped up from about 70 feet per day to nearly 110.
The melting is driven by a warmer climate. Temperatures in Greenland have risen more than five degrees Fahrenheit(華氏溫度) in the last ten years. Since most of Greenland’s ice is on land, seas will rise as the ice melts. If all Greenland’s ice sheet melted, oceans would be 15-20 feet higher. Nobody expects that to happen any time soon.
小題1:What can we know about the glaciers according to the passage?
A.Glaciers only lie in Greenland.
B.Water in glaciers is more than sea water.
C.Glaciers sometimes float on the water.
D.Glaciers can increase the water level of lakes.
小題2:According to the passage, we know that Greenland ___________.
A.belongs to Canada
B.is the largest island in North America
C.is all covered with glaciers
D.is sinking under the sea level
小題3:Which of the following may be the result of the disappearing of Greenland glaciers?
A.The climate of the world will be warmer.
B.The glaciers in other areas will be bigger.
C.It will be easy for explorers to visit the island.
D.Some coastal cities may be under the sea.

Research suggests that a newly-identified gene known as insomniacs(失眠癥患者) may play a role in keeping us asleep. By cloning and testing this gene in about 21,000 fruit flies, Rockefeller University researchers say they have discovered an entirely new mechanism (機制) by which sleep is controlled.
By studying these flies, the researchers discovered that mutations(變異) in the insomniac gene were associated with a great reduction in sleep. While a typical fruit fly slept for an average of 927 minutes a day, the mutant flies slept for just 317. They also slept for shorter periods of time, and slept and woke more frequently.
“The results showed a great loss of both the time that the flies’ sleep lasted and their ability to remain asleep after they slept,” says researcher Nicholas Stavropoulos.
The researchers also examined the link between sleep and lifespan, finding that flies with mutations to the insomniac gene lived only about two-thirds as long as unchanged flies. But when the scientists removed insomniac only in neurons(神經(jīng)細(xì)胞)---allowing it to remain in the rest of the flies’ bodies---this difference disappeared; the resulting animals slept poorly but lived just as long.
“This suggests that reduced sleep can be ‘uncoupled’(分開) from reduced lifespan, supporting the idea that some interruptions of sleep do not affect overall health, at least as far as lifespan is concerned,” Stavropoulos says.
Although flies and humans would appear to have little in common when it comes to lifestyle, scientists say that the mechanisms of sleep and wakefulness are likely to be quite similar.
“Sleep is a fundamental behavior in all animals, and it is poorly understood from a scientific standpoint, says Stavropoulos. This work could prove useful in understanding and treating sleep disorders”
小題1:The text is mainly about____.
A.the progress in cloning fruit flies
B.the methods of cloning fruit flies
C.the link between gene and lifespan
D.the influence of a gene on the ability to sleep
小題2:According to paragraph2, the mutant flies________.
A.slept about 5 hours a day
B.had problems waking up
C.didn’t seem sleepy at all
D.could not fall asleep
小題3:We can conclude from the text that________.
A.sleep and health go hand in hand
B.sleep can be controlled by humans
C.research into sleep is very fruitful
D.the findings are useful in medical treatment

An allowance(零花錢) is an important tool for teaching kids how to make plans for the use of money, save and make their own decisions. Children remem­ber and learn from mistakes when their own dollars are lost or spent foolishly.
How large an allowance is suitable? Experts say there is not right amount. Actual amounts differ from region to re­gion, and from family to family.
To set an suitable allowance for your child, work up a weekly plan. Allow for entertainment costs such as movies and snacks. Next, include everyday expenses such as lunch money, bus fare, school supplies. "If you make the child responsible for these bills’," says Josephine Swanson, a consumer specialist, " he or she will learn to plan for nec­essary costs."
Finally, add some extra money to make saving possible. If you can keep your child’s allowance in line with that of his friends. A child whose buying power falls away below his peers’ can feel left out.
It can be tough, but don’t excuse your children when they make a mistake with their allowance. When Brooke Ste­phens was ten and growing up in Jacksonville, her mother gave her $5 a week, $1.75 of which was for bus fare and lunch." If you lose your money," Brooke’s mother told her, "you walk home."
One week the girl spent all her allowance in a candy store, then she called home for a ride. " Mom made me walk home," recalls Stephens, now a financial planner in Brook­lyn. " At first I was angry. But I finally realized that she was trying to teach me an important lesson. "
Experts advise that an allowance should not be tied di­rectly to a child’s daily housework at home. Kids should help around the house not because they get paid for it but because they share responsibilities as members of a family. You might, however, pay a child for doing extra jobs at home, which can develop his or her early habits.
小題1:Which of the following is the possible title of the passage?
A.How to develop a child’s early habits.
B.How to work up an amount of pocket money.
C.How to teach a child about money.
D.How to teach a child to save money.
小題2: It can be inferred from the passage that if a child is given an allowance, he or she may ________.
A.spend all the money very soon
B.fall into the bad habit of wasting money
C.feel responsible and careful about money
D.lose the money and can not return home
小題3: In Paragraph 4, the words “his peers” refer to ________.
A.his parentsB.his friends
C.his financial expertsD.his teachers
小題4: Why does the writer mention Brooke Stephens?
A.To question the opinion about pocket money.
B.To compare Stephens with other financial experts.
C.To explain that parents should be strict when children are developing good habits about money.
D.To suggest pocket money is useless in developing a child’s sense of responsibility.

A.children may feel lonely if they have no pocket money
B.a(chǎn) child’s early good habits can be developed if he or she is paid for all the housework
C.paying children for their housework is no good

Some American parents might think their children need better educations to compete with China and other countries. But how much do the parents themselves need to change?
A new book called Battle Hymn(圣歌) of the Tiger Mother by Amy Chua has caused a debate about cultural differences in parenting. Ms. Chua is a professor at the Yale Law School in New Haven, Connecticut, and the mother of two daughters. She was raised in the American Mid-west by immigrant Chinese parents.
In the Chinese culture, the tiger represents strength and power. In her book, Ms Chua writes about how she demanded excellence from her daughters. For example, she threatened to burn her daughter’s stuffed animals unless she played a piece of music perfectly. She would insult her daughters if they failed to meet her expectations.
Ms. Chua told NBC television that she had a clear list of what her daughters, Sophia and Louisa, were not permitted to do.
“Attend a sleepover, have a playdate, watch TV or play computer games, be in a school play, get any grade less than an ‘A’.”
Many people have criticized Amy Chua. Some say her parenting methods were abusive. She even admits that her husband, who is not Chinese, sometimes objected to her parenting style. But she says that was the way her parents raised her and her three sisters.
Ms. Chua makes fun of her own extreme style of parenting. She says she eased some of the pressure after her younger daughter rebelled and shouted, “I hate my life! I hate you!”
Ms. Chua says she decided to retreat when it seemed like there was a risk that she might lose her daughter. But she also says American parents often have low expectations of their children’s abilities.
“One of the biggest differences I see between Western and Chinese parenting is that Chinese parents assume strength rather than fragility.”
Stacey DeBroff has written four books on parenting. “I think that the stirring of intense debate has to do with what it means to be a successful parent and what it means to be a successful child.”
Ms. DeBroff says Amy Chua’s parenting style is not limited to Chinese families. She says it represents a traditional way of parenting among immigrants seeking a better future for their children.
But she also sees a risk. When children have no time to be social or to follow their own interests, they might not develop other skills that they need to succeed in life. Stacey DeBroff advises parents to develop their own style of parenting and not just repeat the way they were raised.
小題1:According to the passage, which of the following is TRUE about American parents?
A.Some of them expect their children to be competitive.
B.Some of them need to educate themselves better.
C.They should learn from Chinese parents.
D.They care their kids more than Chinese.
小題2:What can we learn about Battle Hymn of the Tiger Mother?
A.It is a list of things for children to do.
B.It is a book about cultural differences.
C.It is a heated debate about parenting.
D.It is a book about how to raise children.
小題3:Based on the passage, Ms. Chua’s parenting is exposed to the following EXCEPT           
A.pressureB.managementC.recreationD.compromise
小題4: Which of the following agrees with Ms. DeBroff?
A.Different cultures have different concepts of values.
B.Chua’s parenting is followed by many American families.
C.Immigrants are always bitterly struggling abroad.
D.Parents had better raise their children in person.
小題5: What’s the author’s attitude towards Ms. Chua’s parenting?
A.PositiveB.InactiveC.IndefiniteD.Negative

From a plane we can see the fields, cities, mountains or seas below. If we go into space, we see more and more of the earth. People and man-made satellites have been sent out into space to look at the earth carefully and people have learnt more about the earth in the last few years.
The sea looks very beautiful when the sun is shining on it. But it can be very terrible when there is a strong wind.
The sea is very big. It nearly covers three quarters of the earth. The sea is also very deep in some places. There is one place and at that place the sea is about 11 kilometers deep. The highest mountain in the world is about 9 kilometers high. If that mountain was put into the sea at that place, there would be still 2 kilometers of water above it!
In most parts of the sea, there are many kinds of fishes and plants. Some live near the top of the sea. Others live deep down. There are also a lot of small living things, and lots of fishes live by eating them.
The sea can be very cold. When people go down, the sea becomes colder and colder. Only some men can go down into the deep sea. But, in 1970, five women scientists (科學(xué)家) lived in the deep sea for fourteen days.

Do you want to live another 100 years or more? Do you want to live never to die? Some experts say, it will be not a dream one day. Modern technology will make it come true. Man will live more years beyond what is now seen as the natural limit of the human life.
“ I think we are knocking at the door of immortality,” said Michael, a professor and author of two books on human life expectancy. “I think by 2075 we will see it and it’s no longer a dream. Human’s life expectancy may have not limit.”
At the meeting in San Francisco, Donald Louria, a professor at New Jersey Medical School said advances in using genes as well as other technology make it likely that humans will live in the future beyond what has been possible in the past. “There is a great push so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 300 or 500 years.”
However, many scientists are doubtful about it and say the human body is just not designed to last more than about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and other parts of the body will finally lead all humans to death.
Scientists also hold different opinions on what kind of life man might live.  “If you pass 120, you know; could you be healthy enough to have good quality of life? It’s a big question.” said Leonard Poon, director of the university center.  “At present people who could get to that point are not in good health at all.”
小題1:The underlined word in the second paragraph probably means _____.
A.dying slowlyB.living longerC.living foreverD.dying quickly
小題2:Donald’s attitude is that______.
A.human beings may never die in the future
B.it is not certain how long humans can live
C.the human body can last about 120 years
D.it is possible for man to live longer in the future
小題3:What would be the best title for this text?
A.Living longer or notB.Science and long living
C.No limit for human lifeD.Healthy lifestyle and living
小題4:In the last sentence “get to that point” means ____.
A.get that ideaB.get to 120 years old
C.know how to live foreverD.have good quality of life
