分析 本文讲述的是音乐的魔力,比语言更有力,会以不同的方式影响着人们.
解答 DCCA
28.D,细节理解题.根据第一段提到A piece of music can produce a response in the heart and mind.Like feeling an electrical current or receiving a personal radio signal,music has a spiritual effect on a person.Different kinds of music influence people in different ways音乐会对人的身心产生影响,不同的音乐用不同的方式来影响人们,所以说音乐是有魔力的,所以D选项是正确的项.
29.C,细节理解题.根据第二段提到And the freshness and lively spirit of the Beatles was exactly what the country needed to refresh itself.正是披头士的这种活力的精神是重振这个国家所需要的,所以C选项是正确的项.
30.C,细节理解题.第二段提到可知音乐可以振奋人心,第三段提到音乐可以激励人心和感知情绪的变化,所以C选项是正确的项没有提到.
31.A,推理判断题.根据第二段提到I have listened to music all my life.When I was twelve years old,the Beatles came to America and my whole world opened up.我一直在听音乐,当我十二岁的时候,披头士来到美国,我的世界也打开了,受到了影响,所以A选项是正确的项.

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (界面) (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic schooling Lausanne, Switzerland, demonstrated(展示)a small robotic wheelchair directed by a person's thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
"Our brain has billions of nerve cells. These send signals through the spinal cord(脊髓)to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles," Tavella says. "Our system allows disabled people to communicate with external world and also to control devices."
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Milan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. "The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair."
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.
1.BCI is a technology that can _________________.
A. help to update computer systems
B. link the human brain with computers
C. help the disabled to recover
D. control a person's thoughts
2.How did Tavella operate the wheelchair in the laboratory?
A. By controlling his muscles.
B. By talking to the machine.
C. By moving his hand.
D. By using his mind.
3.The team will test with real patients to .
A. make profits from them
B. prove the technology useful to them
C. make them live longer
D. learn about their physical condition
4.Which of the following would be the best title for the text?
A. Switzerland, the BCI Research Center
B. New Findings About How the Human Brain Works
C. BCI Could Mean More Freedom for the Disabled
D. Robotic Vehicles Could Help to Cure Brain Injuries

B vitamins(维生素)may offer some protection against the effect of air pollution,a new study suggests.
The scientists say the effect is real but stress the limitations of their work.Follow-up studies are urgently needed, they say,in heavily polluted cities like Mexico.
According to the World Health Organization (WHO),over 90% of the world's population live in heavily-polluted areas.The one of the pollutants that is considered the most dangerous is very fine particulate matter, referred to as PM2.5.At around 1/30 the width of a human hair,PM2.5 can go deep into the human lung and contribute to lung and heart health problems in the young and old.
Scientists have long suspected that PM2.5 causes what are termed epigenetic(表观遗传)changes in our cells that can damage our health.Now in this new human trial,an international team of scientists wanted to see if exposure to concentrations of PM2.5 could be mitigated by daily B vitamins.
Ten volunteers were tested initially exposed to clean air and their basic responses were measured.The same volunteers were later tested with large doses(剂量)of B vitamins while exposed to air containing high levels of PM2.5.The researchers found that a four-week B vitamin intake limited the PM2.5 effect by between 28-76% at ten gene locations.They found a similar reduction in effect on the mitochondrial DNA,the parts of cells that produce energy.
However,the researchers caution that their study,while observing a real effect,has limitations.As well as the small number of participants,there was little information on the size of the B vitamin dose that caused the response.
1.What is the main idea of the text?
A. B vitamins may fight against PM2.5.
B. PM2.5 can lead to epigenetic changes.
C. Further studies should be done on PM2.5.
D. Exposure to PM2.5 is more and more serious.
2.Which can replace the underlined word "mitigated" in Paragraph 4?
A. measured B. ignored
C. reduced D. observed
3.How many limitations does the text mention about the new study?
A. 2. B. 3.
C. 4. D. 5.
4.How does the writer of the text like the new study?
A. He believes it deeply. B. He criticizes it strongly.
C. He thinks it needs testing again. D. He shows no opinion about it.
