Howling is a behavior commonly observed among a wolf pack（群）. As pack animals, wolves work together to hunt and rely on howling as an important means of communication among each other. There are different explanations of a wolf’s howl and it appears that there may be more to discover.
One theory is that wolves howl to bond（结合）better together. It’s almost as if howling together helps the pack stay together, perhaps something similar to people feeling a sense of involvement with each other when singing a song together. But this theory may be wrong, explains Fred H. Harrington, a professor who studies wolf behavior. Indeed, there have been times when wolves have been seen one moment howling in a chorus, and the next, quarreling among each other. It appears that usually the lowest-ranking members of the pack may actually be “punished” for joining in the chorus at times. So is howling a way to strengthen a social bond or just a way to reconfirm status among its members? —Why do wolves howl for sure?
What is clear, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that wolves may separate from one another at times. When this happens, howling appears to be an excellent means of gathering.
Howling, interestingly, is a contagious behavior. When one wolf starts to howl, very likely others will follow. This is often seen to occur in the morning, as if wolves were doing some sort of “roll call” where wolves all howl together to report their presence. What is the possible similarity between wolves’ howling together and human’s singing in chorus?
| A．The act of calling each other. |
| B．The sense of achievement. |
| C．The act of hunting for something. |
| D．The sense of belonging to a group. |
Why does Harrington think the “social bond” theory may be wrong?
| A．Wolves separate from each other after howling. |
| B．Wolves tend to protect their hunting grounds. |
| C．Wolves sometimes have quarrels after howling together. |
| D．Wolves of low rank are encouraged to join in the chorus. |
Researchers are sure that wolves often howl to______.
| A．show their ranks |
| B．find their companions |
| C．report the missing ones |
| D．express their loneliness |
“Howling…is a contagious behaviour” (in the last paragraph) means______.
| A．howling is a signal for hunting |
| B．howling is a way of communication |
| C．howling often occurs in the morning |
| D．howling spreads from one to another |
Little Tommy was doing very badly in math. His parents had tried everything—tutors (家庭教师), cards, special learning centers—in short, everything they could think of. Finally they took Tommy to a catholic (天主教的) school.
After the first day, little Tommy came home with a very serious look on his face. He didn’t kiss his mother hello. Instead, he went straight to his room and started studying. Books and papers were spread (铺开) out all over the room and little Tommy was hard at work. His mother was surprised. She called him down to dinner and as soon as he finished eating, he went back to his room, without a word. In no time he was back hitting the books as hard as before.

Linda Evans was my best friend—like the sister I never had. We did everything together: piano lessons, movies, swimming, horseback riding.
When I was 13, my family moved away. Linda and I kept in touch through letters, and we saw each other on special time—like my wedding (婚礼) and Linda’s. Soon we were busy with children and moving to new homes, and we wrote less often. One day a card that I sent came back, stamped “Address (地址) Unknown. ” I had no idea how to find Linda.
Over the years, I missed Linda very much. I wanted to share happiness of my children and then grandchildren. And I needed to share my sadness when my brother and then mother died. There was an empty place in my heart that only a friend like Linda could fill.
One day I was reading a newspaper when I noticed a photo of a young woman who looked very much like Linda and whose last name was Wagman — Linda’s married name. “There must be thousands of Wagmans,” I thought, but J still wrote to her.
She called as soon as she got my letter. “Mrs Tobin!” she said excitedly, “Linda Evans Wagman is my mother. ”
Minutes later I heard a voice that I knew very much, even after 40 years, laughed and cried and caught up on each other’s lives. Now the empty place in my heart is filled. And there’s one thing that Linda and I know for sure: We won’t lose each other again!The writer went to piano lessons with Linda Evans _______.

Have you seen Jurassic Park? In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected. That’s nothing more than a fiction.
But could we really clone endangered animals?
To date, the most successful attempt to do so was the cloning of a gaur, a rare ox-like animal from southeast Asia. Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a common bacterial infection. Other endangered species that may be cloned include the African bongo antelope (邦戈羚羊), the Sumatran tiger, the cheetah (猎豹), and the giant panda. Next, could we really clone extinct animals?
In theory? Yes. To do this, you need a well-kept source of DNA from the extinct animals such as wool mammoth (毛象), Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate mother.
In reality? Probably not. On the one hand, it’s not likely that extinct animals’ DNA could survive undamaged for such a long time. Cloning extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly well-preserved DNA. On the other hand, for example, a gaur can have a cow as a surrogate mother, definitely not a monkey. But what about an extinct animal as unique as the panda? What species could possibly serve as a surrogate mother?
Cloning presents many exciting possibilities. However, even if extinct animals are brought back, they could not survive in today’s world. Not only do most extinct animals have no habitat to live in, but the other plants and animals they depended on for food may also be gone as well. It can be learned from the passage that ________.
| A．scientists have cloned the African bongo antelope |
| B．both the cheetah and the giant panda live in Asia |
| C．the gaur lives in Asia and is endangered |
| D．the gaur is an extinct species |
The underlined words “a surrogate mother” probably refer to a female who __________.
| A．contributes its eggs to another female |
| B．gives birth to a baby for another female |
| C．gives birth to a baby of its own |
| D．cannot give birth to a baby |
The difficulty in cloning an extinct species is the lack of ______.
| A．both the well-preserved DNA and plants to live on |
| B．both the habitat to live in and the well-preserved DNA |
| C．both habitat to live in and plants to live on |
| D．both the well-preserved DNA and a surrogate mother |
In the author’s opinion, it is possible that ______.
| A．some extinct species may be cloned, but not survive |
| B．extinct species may be cloned and easily survive |
| C．a gaur can have a monkey as a surrogate mother |
| D．all the extinct species may be cloned |

The Ministry of Health has called for more awareness from the public on the mental health of the young，as part of efforts to mark World Mental Health Day.
More than 15 percent of the Chinese youth have been found with mental problems，and about 30 million young people under 17 are suffering from depression，the Shanghai-based Wenhui Daily reported.
The World Health Organization estimated that before 2020，the rate of children with mental problems will increase to 50 percent，and mental problems will become a major factor behind death and illness in the young worldwide.
Deng Xiaohong，the spokesperson for the Beijing Municipal Health Bureau，said rapid social change is one of the reasons behind the rising number of youngsters with psychological problems.
If these mental diseases are not addressed on time，occurrence of crime，drugtaking and other dangerous behavior are expected to rise.
Experts said mental disease could be caused by many factors，such as the inability to handle interpersonal relations well，unstable emotions and pressure from the overload of study. A number of experts have also said the one-child policy is another reason leading to poor mental health in the young.
Children were said to be too “spoiled” and “selfish” in one-child families. Schools in many cities were reported to roll out measures to help students maintain their mental well-being. Yin Jingmiao，a teacher of the Beijing No. 105 Middle School，told China Daily that the school invites psychologists to provide counseling to students three times a month. “Students can be arranged to have 40-minute counseling sessions，” Yin said. The school also gives lectures on mental health to senior grade students before they take the national college entrance exams，to help ease any anxiety arising from the tests.What is the purpose of the passage?
| A．To urge awareness on mental health of the young. |
| B．To give the details of the problems the Chinese youth are facing today. |
| C．To recommend that schools should invite more psychologists to help solve the mental problems among the youth. |
| D．To show us the causes of the mental problems among students. |
The underlined word “addressed” in the fifth paragraph most probably means ________.
| A．talked about | B．dealt with |
| C．satisfied | D．introduced |
From the passage we can know that the causes of mental problems are mainly the following EXCEPT ________.

One of my wonderful memories is about a Christmas. Unlike other gifts, it came without wrap.
On September 11th, 1958, Mum gave birth to Richard. After she brought him home from hospital, she put him in my lap, saying, “I promised you a gift, and here it is. “ What an honor! I turned four a month earlier and none of my friends had such a baby doll of their own. I played with it day and night. I sang to it. I told it stories. I told it over and over how much I loved it!
One morning, however, I found its bed empty. My doll was gone! I cried for it. Mum wept and told me that the poor little thing had been sent to a hospital. It had a fever. For several days, I heard Mum and Dad whispering such words as “hopeless”， “pitiful”， and “dying”， which sounded ominous.
“Christmas was coming. Don't expect any presents this year，” Dad said, pointing at the socks I hung in the living room. “If your baby brother lives, that'll be Christmas enough.” As he spoke, his eyes were filled with tears. I'd never seen him cry before.
The phone rang early on Christmas morning. Dad jumped out of bed to answer it. From my bedroom I heard him say, “What? He's all right？” He hung up and shouted upstairs. “The hospital said we can bring Richard home！”
“Thank God！” I heard Mum cry.
From the upstairs window, I watched my parents rush out to the car. I had never seen them so happy. And I was also full of joy. What a wonderful day! My baby doll would be home. I ran downstairs.
