For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive to such messages.
Scientists are using powerful radio telescopes to listen to signals from about 1, 000 stars, all within 100 light years of earth. In addition, they will scan（扫视）the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal they stands out from the background noise.
Of the 200 billion stars in the Milky Way galaxy（银河星系）, scientists find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution（进化）of life. Based on the inhabitable（that can be lived in）planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.
However, many scientists wonder whether intelligent（有智力的）life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.
Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is only about five billion years old, our galaxy is about 20 billion years old. In that time, some scientists think it is likely that civilization（文明）much more advanced than ours have developed. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.According to the passage, how many planets in our galaxy might be inhabitable?

Wolves travel in groups, and they perform almost all the other activities of their lives in the company of fellow wolves. This is one of the most important facts that modern science have learned about wolves and one of the things that most clearly explain their way of life.
The pack is usually a family group. It is made up of animals related to each other by blood. The centre of a pack is a pair of wolves----an adult male and female that have produced young. The other members of the pack are their offspring (后代): young wolves ranging in age from pups to two- and three-year-olds. Most packs have 6 or 7 members, although some may include as many as 15 wolves.
Relationships among creatures that live close together in groups are often very complex, and this is true of the ties that connect the members of a wolf pack. Scientific studies of captive(被捕获的) wolves and wolf packs in the wild have shown that many complex rules of behavior seem to govern the way that the animals relate to each other.
When wolf pups are born into a pack, one of the most important things they must learn is the “language” of the group, the method by which pack members keep in touch with each other, sharing information and communicating their feelings. Scientists have discovered that wolves have a very complex system of communication.
The most famous wolf sound is, of course, the howl, and it is a very important part of wolf language.
When people think about howling, they usually imagine a sad, lonely sound made by a wolf sitting all alone on a hilltop in the moonlight. However, this picture in most human beings’ mind is not completely true. Wolves howl at any time, not just at night, and they often howl together, not alone.
Group or chorus howling is another means by which the members of a wolf reaffirm(重申) their ties with each other and their closeness as a group. One wolf----often the male leader----will point its nose at the sky, open its mouth, and start to howl. Immediately the other members of the pack rush to stand beside him, shoulder to shoulder, and join their voices to his. Each wolf howls on its own note so that a big chorus of slightly different sounds is produced.
Chorus howling often takes place before a wolf pack goes out to hunt. At the end of a successful hunt, the pack may also celebrate with a group howl. While wolves are on the track of prey(猎物)，they are usually silent.
There are occasions when a wolf will howl by itself. This may happen when an animal is separated from the pack. Pack members seem to recognize each other’s voices and will keep responding to the howl of their wandering relative until the group is reunited.
Because howling is a sound that carries over a considerable distance, it is very useful in communications among separated members of a pack. Howling is also used when members of different packs have to get in touch with each other to pass on information about their locations and their purposes.What makes communication the most important part of wolves’ lives?
| A．Living in packs | B．Hunting at night |
| C．Occupying a large area | D．Finding fellows |
What most likely happens to young wolves after the age of four?
| A．They leave the pack and live alone. |
| B．They leave the pack to form packs of their own. |
| C．They continue to live as part of the pack. |
| D．They take over the leadership from their parents. |
How many members do most wolf packs consist of?
| A．3—4 | B．4---5 | C．6---7 | D．10---15 |
To what human activity could wolves’ “chorus howling” best be compared?
| A．A baby crying from hunger |
| B．A family having an argument |
| C．A group of people singing at a concert |
| D．A sports team cheering before a game |
When will wolves howl according to the passage?
| A．Only during the night. | B．When separated from the pack |
| C．When there is moonlight | D．While on their way to tracking prey |
In the second half of each year, many powerful storms are born in the tropical Atlantic and Caribbean seas. Of these, only about a half a dozen generate (引起，导致) the strong, circling winds of 75 miles per hour or more that give them hurricane status, and several usually make their way to the coast. There they cause millions of dollars of damage, and bring death to large numbers of people.
The great storms that hit the coast start as innocent circling disturbances hundreds--- even thousands--- of miles out to sea. As they travel aimlessly over water warmed by the summer sun, they are carried westward by the trade winds. When conditions are just right, warm, moist air flows in at the bottom of such a disturbance, moves upward through it and comes out at the top. In the process, the moisture in this warm air produces rain, and with it the heat that is converted to energy in the form of strong winds. As the heat increases, the young hurricane begins to swirl in a counter-clockwise (逆时针方向) motion.
The average life of a hurricane is only about nine days, but it contains almost more power than we can imagine. The energy in the heat released by a hurricane’s rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months.
Water, not wind, is the main source of death and destruction in a hurricane. A typical hurricane brings 6 to 12 inch downpours resulting in sudden floods. Worst of all is the powerful movement of the sea, the mountains of water moving toward the low-pressure hurricane center. The water level rises as much as 15 feet above normal as it moves toward shore.When is an ordinary tropical storm called a hurricane?
| A．When it begins in the Atlantic and Caribbean seas. |
| B．When it hits he coastline. |
| C．When it is more than 75 mils wide. |
| D．When its winds reach 75 miles per hour. |
What is the worst thing about hurricane?
| A．The destructive effects of water. |
| B．The heat they release. |
| C．That they last about nine days on the average. |
| D．Their strong winds. |
The counter-clockwise swirling of the hurricane is brought about by .
| A．the low-pressure area in the center of the storm |
| B．the force of waves of water. |
| C．the trade winds |
| D．the increasing heat |
Apparently the word “downpour” in the fourth paragraph means.
| A．heavy rainfall |
| B．dangerous waves |
| C．the progress of water to the hurricane center |
| D．the increasing heat |
Henry Edwards Huntington was born in 1850 in Oneonta, New York. In 1872 he went to work for his uncle, one of the owners of the Central Pacific Railroad. Twenty years later, Huntington moved to San Francisco at his uncle’s request to share management of the Southern Pacific Railroad. On the way to San Francisco, he visited San Marino, and later bought it, which is home to his collections today.
In 1902, Huntington moved his business operations to Los Angeles, where he developed the street railway system that created the structure of the Los Angeles area. He greatly expanded the existing electric railway lines, creating an extensive inter-urban system providing the transportation necessary. Huntington’s business interests continued to grow particularly in the areas of water, power, and land development; at one time he served on as many as 60 corporate boards throughout the United States.
At the age of 60, he announced his decision to retire in order to devote time to his book and art collections and the landscaping of the 600-acre farm. In 1911 the large Beaux Arts building, in the charge of the architect Myron Hunt, was completed.
In 1913, Huntington married Arabella Duval Huntington. She shared his interests in collecting. As one of the most important art collectors of her generation, she was highly influential in the development of the art collection now shown in the former building.
In 1919, Henry and Arabella Huntington signed the agreement that conveyed their San Marino property and collections to a nonprofit educational trust, creating the Huntington, one of the world’s great cultural, research, and educational centers.
Henry E. Huntington died in 1927, leaving his great treasures the Huntington, including the world-famous Huntington Library, Art Gallery, and Botanical Gardens in San Marino, California to the public, which hosts more than 500,000 visitors each year. What can you learn about Huntington from the first two paragraphs?
| A．He worked in many fields before he came to Los Angeles. |
| B．He built a house to store his art collection in San Marino. |

[1] More than 40 million Americans move each year, but not always by choice. Whether you relocate because of a new job or school for you or your spouse, for a lower cost of living, or for better opportunities, adjusting to life in a new place can be scary and difficult--especially when you’re not in love with your new city. Here are some tips on how to make the most of your relocation and find happiness in your new home.
[2] Treat it as an adventure
Living in a new place is a great opportunity to experience new things and to grow as a person. So stay positive, and get out there and explore! Sample the local cuisine. Visit landmarks and museums. Try local activities that weren’t available or popular in your former city, such as skiing if you came from a beach town or surfing if you lived in the mountains. You may discover a talent or interest you never knew you had.
[3] Get involved
Attend local events that interest you. Visit the weekly farmer’s market or the neighborhood yard sale. Volunteer. Take a class. Join a sports league. All of these things will help you meet people and feel connected to your new town.
[4] Locate the necessities
Driving, riding, or walking around your new neighborhood is the best way to learn where everything is. So head out and take note of the nearest supermarket, pharmacy, post office, library, etc.
[5] Keep pieces of your old home
To keep from getting too homesick, subscribe to your former city magazine or newspaper. Display photos of or souvenirs from your favorite places in your old town. Hang decorations from your former home. Just don’t go overboard—hanging on to too much from your past will keep you from moving forward and really enjoying your new home.
[6] _________

I was brought up in the British, stiff upper lip style. Strong feelings aren’t something you display in public. So, you can imagine that I was unprepared for the outpouring of public grief(悲伤) at a Chinese funeral.
My editorial team leader died recently after a short illness. He was 31. The news was so unexpected that it left us all shocked and upset. A female colleague burst into tears and cried piteously at her desk. Somehow we got through the day's work. The next day was the funeral.
Our big boss stepped forward to deliver a eulogy(悼词) and was soon in tears. She carried on, in Chinese of course, but at the end said in English: "There will be no more deadlines for you in heaven." Next came a long-term colleague who also dissolved in tears but carried on with her speech despite being almost overcome by emotion. Then a close friend of the dead man paid tribute(哀悼), weeping openly as he spoke. Sorrow is spreading. Me and women were now sobbing uncontrollably. Finally, the man's mother, supported between two women, addressed her son in his coffin. At one point, the mother almost collapsed and had to be held up. We were invited to step forward to each lay a white rose on the casket. Our dead colleague looked as if he was taking a nap. At the end of the service I walked away from the funeral parlor stunned at the outpouring of emotion.
In the UK, families grieve privately and then try to hold it together and not break down at a funeral. Here in China it would seem that grieving is a public affair. It strikes me that it is more cathartic to cry your eyes out than try to keep it bottled up for fear of embarrassment, which is what many of us do in the West.
Afterwards, a Chinese colleague told me that the lamenting at the funeral had been restrained(克制) by Chinese standards. In some rural areas, she said, people used to be paid to mourn noisily. This struck me like something out of novel by Charles Dickens. But we have all seen on TV scenes of grief-stricken people in Gaza and the West Bank, in Afghanistan, Iraq and the relatives of victims of terrorist bombings around the world. Chinese grief is no different. I realized that it's the reserved British way of mourning that is out of step with the rest of the world.
It was our newspaper's production day. We were bussed back to the office to resume work. No more deadlines for our former colleague, but we had to pull together to put the newspaper to print. The boss invited the team to go out for dinner after work. We relaxed, smiled, joked. There was no mention of the funeral or our poor colleague. Enough sorrow had been shed already. We needed a break.The underlined words “stiff upper lip style” in Paragraph 1 mean “________”.
| A．cold-blooded | B．warm-hearted | C．light-hearted | D．self-controlled |
At the funeral, ________.
| A．five individuals made speeches |
| B．the boss’s speech was best thought of |
| C．the writer was astonished by the scene |
| D．everyone was crying out loudly |
According to the writer, people in the West ________.
| A．are not willing to be sad for the dead |
| B．cry their eyes out at the public funeral |
| C．prefer to control their sadness in public |
| D．have better way to express sadness |
It is implied that ________.
| A．Chinese express their sadness quite unlike other peoples |
| B．the English might cry noisily for the dead in Dickens’ time |
| C．victims of terrorist bombings should be greatly honored |
| D．English funeral culture is more civilized than the others |
This passage talks mainly about________.
| A．an editor’s death | B．bad funeral customs |
| C．cultural differences | D．western ways of grief |
