They never talk about religion or matters of finance, education or politics, but usually stay with safe subjects like the weather, films, plays, books and restaurants.”

1970 was World Conservation Year.The Unite Nations wanted everyone to know that the world is in danger.They hoped that governments would act quickly in order to“conserve”nature.Here is one example of the problem.At one time there were 1 000 different plants，trees and flowers in Holland，but now only 860 remain.The others have been destroyed by modern man and his technology.We are changing the earth，the air and water，and everything that grows and loves.We can’t live without these things.If we continue like this，we shall destroy ourselves.

What will happen in the future? Perhaps it is more important to ask，“What must we do now?”The people who will be living in the world of tomorrow are the young of today.A lot of them know that conservation is necessary.Many are hoping to save our world.They plant trees，build bridges across rivers in forests，and so on.In a small town in the United States a large group of girls cleaned the banks of 11 kilometers last Sundays in order to protect their surroundings.“No one’s going to change our world”is popular with others.It was made by the Scathes Cliff Richard and other singers.The money from it will help to conserve wild animals.

Learning to play a musical instrument can change your brain, with a US review finding musical training can lead to improved speech and foreign language skills.
Although it was suggested in the past that listening to Mozart’s music or other classical music could make you smarter, there has been little evidence to show that music can boost(使增长) brain power.
But a data-driven review by Northwestern University has pulled reaserch together that links musical training to learning that spills over into (波及) skills including language, speech, memory, attention and even vocal emotion.
Researcher Nina Kraus said the data strongly suggested that the nervous connections made during musical training also prepared the brain for other aspects of human communication.
“ The effect of musical training suggests that, like physical exercise and its effect on body fitness, music is a resource that tones the brain for auditory fitness and thus requires society to re-examine the role of music in shaping individual development, ” the researchers said in their study.
Kraus said learning musical sounds could improve the brain’s ability to adapt and change and also enable the nervous system to provide constructing patterns that are important to learning.
The study, published in Nature Review Neuroscience , looked at the explosion of research in recent years focusing on the effect of musical training on the nervous system which could have impacts for education.
The study found that playing an instrument prepares the brain to choose what is related in a complex process that may involve reading or remembering a score, timing issues and coordination with other musicians.
【小题1】What is the text mainly about ?

A．The effect of physical exercise.	B．The researcher named Kraus.
C．The benefit of musical training.	D．Musicians’ improved skills.

【小题2】The underlined word “ auditory ” in Paragraph 5 probably means “ __________”.

A．of the body	B．connected with seeing
C．of the mind	D．connected with hearing

【小题3】It was believed but not proved that listening to classical music could __________.

A．add to your intelligence	B．improve your speech
C．boost your memory	D．make you think faster

【小题4】According to Kraus, musical training contributes to the following EXCEPT __________.

A．body fitness	B．the way to speak
C．langugage learning	D．mental concentration

Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health. This explains a warning that cell phone manufacturers include in the small print that is often ignored when a new phone is purchased. Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry’s manufacturer, recommends 2.5 centimeters.
If health issues arise from cell phone use, the possible effects are huge. Voice calls - Americans chat on cell phones 2.26 trillion(万亿)minutes annually - earn $109 billion for the wireless carriers.
Devra Davis, an expert who has worked for the University of Pittsburgh, has published a book about cell phone radiation, “Disconnect.” The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
“Most cancers have multiple causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid（易吸收的液体）. No studies have yet been completed on cell phone radiation and children, she says.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen（腹部）.
【小题1】Why is the warning in the small print?

A．They think people will not care about it.

B．There is not enough space for the warning.

C．They don’t want the users to pay attention to it.

D．The warning is not important at all.

【小题2】 What does the underlined word in sixth paragraph probably mean?

【小题3】What can we conclude from the last paragraph?

A．Pregnant women should keep cell phones away.

B．People should use cell phones in the correct way.
