A recent study conducted by the Pine Street Foundation showed that a dog’s nose may have the ability to detect cancer. A dog’s nose, which was the “medical device” used as part of the research, is believed to be among the world’s most powerful olfactory(嗅觉的) sensors. The study was conducted with 169 subjects 55 of which had been diagnosed as having lung cancer, 31 have breast cancer and 83 control subjects——people without cancer. During the study, five professionally trained scent dogs were used to distinguish between the breath samples of cancer patients and those who were healthy. With an average of 90% accuracy, the research was deemed a success.

The Pine Street Foundation conducted its research on the belief that cancer cells give off a different type of metabolic(新陈代谢) waste product than normal cells. According to the study, the difference is so great that it can be detected by a dog’s sense of smell, including both early and late stages of the disease.

In the conclusion of the study the Pine Street Foundation said that even ordinary dogs may be trained to identify the presence of cancer with only a breath sample. The organization also said that dogs can recognize the disease with astonishing amount accuracy and, finally, that the dog’s detection was not hindered(妨碍) by the presence of age, smoking or stage of cancer.

The Pine Street Foundation plans to continue their research and is currently seeking funding to launch new studies.

A gentle breeze blew through Jennifer’s hair. The golden red sun was setting. She was on the beach, looking up at the fiery (火红的) ball. She was amazed by its color, deep red in the middle, softly fading into yellow. She could hear nothing but the waves and the seagulls flying up above in the sky.
The atmosphere relaxed her. After all she had been through, this was what she needed. “It’s getting late,” she thought, “I must go home. My parents will be wondering where I am.”
She wondered how her parents would react, when she got home after the three days she was missing. She kept on walking, directing herself where she spent every summer holiday. The road was deserted. She walked slowly and silently. Just in a few hundred meters she would have been safe in her house.
It was really getting dark now. The sun had set a few minutes before and it was getting cold too. She wished she had her favorite sweater on: it kept her really warm. She imagined having it with her. This thought disappeared when she finally saw her front door. It seemed different. Nobody had taken care of the outside garden for a few days. She was shocked: her father was usually so strict about keeping everything clean and tidy, and now... It all seemed deserted. She couldn’t understand what was going on.
She entered the house. First, she went into the kitchen where she saw a note written by her father. It said: “Dear Ellen, there is some coffee ready. I went looking.” Ellen was her mother but — where was she? On the right side of the hallway was her parents’ room. She went in. Then she saw her. Her mother, lying on the bed, was sleeping. Her face looked so tired, as if she hadn’t slept for days. She was really pale. Jennifer would have wanted to wake her up but she looked too tired. So Jennifer just fell asleep beside her. When Jennifer woke up, something was different... she wasn’t in her mother’s room and she wasn’t wearing the old clothes she ran away in. She was in her cozy bed in her pajamas (睡衣).
It felt so good being back home. Suddenly she heard a voice, “Are you feeling better now, dear? You know you got us very, very scared.”

　　Young people can have problems with their minds. Some students become worried because they have to study very hard. Others have trouble getting on well with people like their parents and classmates.
Liu Wei, a Junior 2 student from Hefei, could not understand his teacher and was doing badly in his lessons. He became so worried about it that he started to cut his finger with a knife. Another student, 14-year-old Yan Fang from Guangzhou, was afraid of exams. She got very worried in the test, and when she looked at the exam papers, she couldn’t think of anything to write.
A recent report from Jiefang Daily says about 18% of Shanghai teenagers have mental(心理的)problems. Their troubles include being worried and very unhappy, and having problems in learning and getting on well with people. Many students who have problems won’t go for advice or help. Some think they will look stupid(愚蠢的)if they go to see a doctor. Others don’t want to talk about their secret.
Liang Yuezhu, an expert on teenagers from Beijing Anding Hospital has the following advice for teenagers.

Will you get a good job？ What will you do？ Many new graduates feel lost when they consider the endless list of career choices. They’ve invested a lot of money for their diploma（文凭）and now an important question stares them in the fact.
I’ve seen so many now graduates who do not know how to use the degree they have just earned. An example was Dave，who loved sports and had played baseball throughout his college years. He had his heart set on working for Nike. But he had never made clear in his own mind what kind of job he could do for Nike，so nothing ever happened. Another example was Allison，who was a history major. She wanted to work as an event planner，but unfortunately，no one hired her. Why？ No experience.
Failing to do some solid career exploration first，to get a clear idea of the types of jobs you can do，is a big error that many college students make. After our suggestion，Dave and Allison both found their jobs. To ensure a brighter future，follow these effective strategies：
—Make educated career choices. Identify the job you want. Conduct research. Ask parents to advise you on actual job duties. Consider what your natural talents are，and look for positions where you can use them.
—Don’t rely on the Internet. Networking is an effective tool—be sure it’s a job—hunting strategy you use. New studies from the Department of Labor state that only 4％ of job-seekers found their job on the Internet. The fact is that 63％ of all jobs are filled by contacts.
Employers are making quick decisions. Most people lose the job in the first minute of the interview. It’s deadly to let the employers focus quickly on how well you can perform the job.
—Practice your interviewing skills. Be ready for the tough questions by first writing out good answers to possible questions and having a role-playing interview with your friend.
60．What does the author seem to be most probable？
