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.

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 ________.
| A．one-child policy |
| B．lack of ability to handle interpersonal relations well |
| C．lack of special training in mental health |
| D．heavy burden from study |
Which of the following statements is true according to the passage?
| A．By 2020，about 50 percent of the students in China will have mental problems. |
| B．Mental problems mainly appear among the youth while they are seldom seen among adults. |
| C．China has the largest number of youngsters with psychological problems. |
| D．Many schools have realized the problem and taken measures. |

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. My socks still hung there flat. But I knew they were not empty; they were filled with love!What happened to the author on September 11th, 1958?

American scientists have developed the first material that repairs itself. The material is a form of plastic that has been engineered to fill breaks in its surface.
Plastics are used today in everything. Scientists wanted to find a way to make objects made of plastic last longer. The researchers hope their new discovery can be used to make objects that are difficult or impossible to replace.
The surface of plastic objects breaks over time. Very small breaks develop every time a plastic object is used. The researchers wanted to find out how to stop plastic from developing small breaks that weaken and destroy it. They found the answer in the chemical structure of plastic itself. The research team found a way to make plastic that contains very small balloons filled with monomer(单体) liquid. When the new plastic cracks, the monomer liquid is let out and flows into the crack. Thus the break is repaired. The repaired plastic has seventy-five percent of the strength of undamaged plastic.
The new self-repairing plastic is not yet ready for production. But it has several possible uses. One could be in space vehicles where parts cannot be repaired or replaced. Another possible use might be in bridges. And it could be used in people, to replace bone joints that have become broken or damaged.The passage mainly talks about_______ .
| A．plastic that repairs itself |
| B．the chemical structure of plastic |
| C．permanent material invented |

We know from the passage that the repair is done as_______.
| A．the cracked plastic parts are changed |
| B．the plastic cracks |
| C．the liquid is put into the plastic cracks |
| D．the plastic is made |

| A．the plastic parts in them are required to last longer |
| B．they want to experiment in these places first |
| C．the new material cannot be used elsewhere |
| D．the plastic parts in them are easily broken or damaged |
