A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin caner, actually increases the risk.Researchers from the University of Yale based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanomas (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer—people with fair skin and freckles (雀斑), for example—are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.The underlined word “flaws” in the 2nd paragraph most probably means .
| A．evidences | B．facts | C．faults | D．failures |
People with fair skin and freckles .
| A．seldom use sunscreen | B．are more in danger of skin cancer |
C．can be free from the harm of the sun | D．often expose themselves to the sun |
We can learn from the passage that .
| A．sunscreen users get skin cancer more often |
B．the volunteers have prov ed the effect of sunscreen |
C．the new study was based on the experiences of volunteers |
D．the number of skin cancer patients is increasing in America |
Which of the following can be the best title for this passage?

At a day care center in Texas, children were playing outside. One of the children was Jessica McClure. She was only 18months old. Her mother, worked at the day care center , was watching the children . Suddenly Jessica fell and disappeared. Jessica’s mother screamed and ran to her.
A well was in the yard of the center. The well was only eight inches across and a rock always covered it. But children had moved the rock. When Jessica fell, she fell right into the well.

New findings show that musical training affects（影响）the structure and function of different brain areas, how those areas communicate during the creation of music, and how the brain interprets and combines sensory(感官) information. The findings were presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world’s largest source of emerging news about brain science and health. These views suggest potential new roles for musical training including training plasticity（可塑性）in the brain, offering an alternative tool in education, and treating a range of learning disabilities.
Today’s new findings show that long-term high level musical training has a broader effect. Researchers found that musicians have a better ability to combine sensory information from hearing, touch, and sight. The age at which musical training begins influenced brain structure and its function. Beginning training before the age of seven has the greatest effect.
Even older adults who took music lessons as children but haven’t actively played an instrument in decades have a faster brain response(反应) to a speech sound than those who never played an instrument, according to a study appearing November 6 in the Journal of Neuroscience. The finding suggests early musical training has a lasting, positive effect on how the brain deals with sound.
“Playing a musical instrument is a multi-sensory and motive experience that creates emotions and movements—from finger tapping to dancing — and engages pleasure and reward systems in the brain. It has the potential to affect brain function and structure when done over a long period of time,” said Gottfried Schlaug, MD, PhD, of Harvard Medical School, press conference speaker, also an expert on music.
“As today’s findings show, musical training brings about new processes within the brain, at different stages of life, and with a range of effects on creativity, cognition(认知), and learning,” he added. From the first paragraph, we can see musical training can .
| A．affect one’s communication with others |
| B．help musicians create better music |
| C．provide new treatment of mental diseases |
| D．offer an alternative tool in education |
Why does the author mention “Even older adults … a speech sound.” in Para. 3?

| D．To show how the brain areas communicate in music training. |
Which of the following best describes the function of early musical training?
| A．Difficult but interesting. | B．Painful but effective. |
| C．Lasting and positive. | D．Important and necessary. |
According to the passage, we learn that .

When I was a kid, I was close to my dad, but as I grew older, my dad and I grew further apart. We always had totally different opinions. He thought that college was a waste of time, but for me it was important to finish college. He wanted me to work my way to the top as he had done in his field, but I wanted a different life. There was a time when we did not talk with each other.
A few months ago, I heard that my 84-year-old dad was in poor health. When he called and asked whether I could move from Colorado back to Tennessee to help him, I knew he was seriously ill. I am his only child and so it was time to meet my father’s requirement.

Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships. One strength of the human conditions is our possibility to give and receive support from one another under stressful(有压力的) conditions. Social support makes up of the exchange of resources among people based on their interpersonal ties. Those of us with strong support systems appear better able to deal with major life changes and daily problems. People with strong social ties live longer and have better health than those without such ties. Studies over types of illnesses, from depression to heart disease, show that the presence of social support helps people defend themselves against illness, and the absence of such support makes poor health more likely.
Social support cushions stress in a number of ways. First, friends, relatives and co-workers may let us know that they value us. Our self-respect is strengthened when we feel accepted by others in spite of our faults and difficulties. Second, other people often provide us with informational support. They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Taking part in free-time activities with others helps us to meet our social needs while at the same time distracting (转移注意力) us from our worries and troubles. Finally, other people may give us instrumental support — money aid, material resources, and needed services — that reduces stress by helping us resolve and deal with our problems.Interpersonal relationships are important because they can _______.
| A．make people live more easily |
