For some people, music is no fun at all. About four percent of the population is what scientists call “amusic.” People who are amusic are born without the ability to recognize or reproduce musical notes (音调). Amusic people often cannot tell the difference between two songs. Amusics can only hear the difference between two notes if they are very far apart on the musical scale.

As a result, songs sound like noise to an amusic. Many amusics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. Their inability to enjoy music set them apart from others. It can be difficult for other people to identify with their condition. In fact, most people cannot begin to grasp what it feels like to be amusic. Just going to a restaurant or a shopping mall can be uncomfortable or even painful. That is why many amusics intentionally stay away from places where there is music. However, this can result in withdrawal and social isolation. “I used to hate parties,” says Margaret, a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret, scientists are finally learning how to identify this unusual condition.

Scientists say that the brains of amusics are different from the brains of people who can appreciate music. The difference is complex, and it doesn’t involve defective hearing. Amusics can understand other nonmusical sounds well. They also have no problems understanding ordinary speech. Scientists compare amusics to people who just can’t see certain colors.

Many amusics are happy when their condition is finally diagnosed (诊断). For years, Margaret felt embarrassed about her problem with music. Now she knows that she is not alone. There is a name for her condition. That makes it easier for her to explain. “When people invite me to a concert, I just say, ‘No thanks, I’m amusic,’” says Margaret. “I just wish I had learned to say that when I was seventeen and not seventy.”                                                                                                                       (335 words)

1.Which of the following is true of amusics?

A．Listening to music is far from enjoyable for them.

B．They love places where they are likely to hear music.

C．They can easily tell two different songs apart.

D．Their situation is well understood by musicians.

2.According to paragraph 3, a person with “defective hearing” is probably one who __________.

A．dislikes listening to speeches

B．can hear anything nonmusical

C．has a hearing problem

D．lacks a complex hearing system

3.In the last paragraph, Margaret expressed her wish that __________.

A．her problem with music had been diagnosed earlier

B．she were seventeen years old rather than seventy

C．her problem could be easily explained

D．she were able to meet other amusics

4.What is the passage mainly concerned with?

A．Amusics’ strange behaviours.

B．Some people’s inability to enjoy music.

C．Musical talent and brain structure.

D．Identification and treatment of amusics.

Maps of the world’s population show that the majority of people today live near water. 1.We also vacation at the beach and find comfort fishing on a lake. Nothing makes small children happier than the chance of playing in water. More interesting, this human favor for water makes evolutionary sense. 2.

Neuroscientist(神经系统科学家) Michael Crawford of the University of North London has proposed that our ancient ancestors attached to the sea, and that their devotion paid off by allowing the human species to develop large and complex brains. Crawford claims that when humans separated from apes and appeared in the forests of Africa, they stuck close to rivers and beaches and started catching fish and crabs.3.

It's no coincidence, Crawford claims, that human brain growth began to increase rapidly once we left the woods and headed for the beach.

4.Psychiatrist(精神病学家)and biochemist Joseph Hibbelin of National Institutes of Health has shown that across cultures there is direct link between amount of fish eaten each week and rates of depression. More interesting, Hibbelin and researcher Laura Reis have found that fish is commonly used as a symbol of happiness and good health in various religions and cultures.

5.We vacation on the coast and see the waves come and go, feeling happiness has taken over our brain. When we move inland, or go home from vacation, we lose touch with our sea roots and feel unhappy.

A. Sure, we need drinking water to live, but we have also benefited from what’s swimming under waves.

B. We know that fish and the sea are good for us, and we seek them out.

C. We live along coastlines, around bays, up the course of rivers and streams and on islands.

D. Scientists help people overcome depression.

E. Scientists have also discovered that people who eat fish regularly are less likely to suffer from depression than those who eat less seafood.

F. It is good for our health to swim under the waves.

G. That sea food was packed with omega-3 fatty acids, essential fatty acids that promote brain cell growth.

Four people in England, back in 1953, stared at photo 51. it wasn’t much –a picture showing a black X. But three of these people won the Nobel prize for figuring out what the photo really showed—the shape of DNA. The discovery brought fame and fortune to scientists James Watson, Francis crick, and Maurice Willkins. The fourth, the one who actually made the picture, was left out.

Her name was Rosalind Franklin. “She should have been up there,” says historian Mary Bowden. ”if her photo hadn’t been there, the others couldn’t have come up with the structure.” one reason Franklin was missing was that she had died of cancer four years before the Nobel decision. But now scholar doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitions.

At Cambridge University in the 1950s, Watson and Crick tried to make models by cutting up shapes of DNA’s parts and then putting them together. In the meantime, at king’s college in London, Franklin and Wilkins shone X-rays at the molecule（分子）. The rays produced patterns reflecting the shape.

But Wilkins and Franklin’s relationship was a lot rockier than the celebrated teamwork of Watson and Crick. Wilkins thought Franklin was hired to be his assistant. But the college actually employed her to take over the DNA. project.

What she did was produce X-ray pictures that told Watson and Crick that one of their early models was inside out. And she was not shy about saying so. That angered Watson, who attacked her in return,” Mere inspection suggested that she would not easily bend. Clearly she had to go or be put in her place.

As Franklin’s competitors, Wilkins, Watson and Crick had much to gain by cutting her out of the little group of researchers, says historian Pnina Abir-Am. In 1962 at the Nobel prize awarding ceremony, Wilkins thanked 13 colleagues by name before he mentioned Franklin. Watson wrote his book laughing at her. Crick wrote in 1974 that “Franklins was only two steps away from the solution.”

No, Franklin was the solution.” She contributed more than any other player to solving the structure of DNA. She must be considered a co-discoverer,” Abir-Am says. This was backed up by Aaron Klug, who worked with Franklin and later won a Nobel Prize himself. Once described as the “Dark Lady of DNA”, Franklin is finally coming into the light.

1.What is the text mainly about?

A. The disagreements among DNA. researchers.

B. The unfair treatment of Franklin.

C. The process of discovering DNA.

D. The race between two teams of scientists.

2.Watson was angry with Franklin because she ______.

A. took the lead in the competition

B. Kept her results from him

C. proved some of his findings wrong

D. shared her data with other scientists

3.Why is Franklin described as “Dark Lady of DNA”?

A. She developed pictures in dark labs.

One in four children and young people could have problematic smart-phone use, according to research that also suggests such behaviour is associated with poorer mental health.

The amount of time children and teens spend using their devices has become an issue of growing concern, but experts say there is still little evidence as to whether spending time on screens is harmful in itself.

The experts behind the latest study said they wanted to look beyond the time young people were spending on smart-phones and instead explore the type of relationship they had with smart-phones.

The results suggest more than 23% of young people have an abnormal relationship with their smart-phones, and that this appears to be associated with poorer mental health-although the research cannot say whether phone use is driving such problems.

“It seems like only a minority of teenagers and young people from various different countries are self-reporting a pattern of behaviour that we recognise from other addictions,” said Dr Nicola Kalk of King’s College London, co-author of the study. “The quality of the evidence is poor, but it is enough to warrant (保证) further investigation.”

Writing in the journal BMC Psychiatry, the team reported how they looked at data from 41 studies involving a total of almost 42,000 participants across Europe, Asia and America, mainly in their teens or early 20s.

These studies used questionnaires to probe the prevalence (普遍) of problematic smart-phone use-behaviours such as being anxious when the device is not available or neglecting other activities to spend time on the smart-phone.

Taken together, the team said on average these studies suggested as many as one in four children and young people had problematic smart-phone use.

Among the studies that probed mental health, the results suggested people with problematic smart-phone use were also more likely to have depression-for which the odds (可能性) were more than three times worse-anxiety, feelings of stress and poor sleep as well as poorer educational attainment.

While the team said it was too soon to call problematic smart-phone usage an addiction, they noted that it appeared to be linked to similar patterns of behaviour and emotion.

Kalk said further studies were needed to explore if these behaviours were hard to break, or cause harm-other key features of an addiction.

The authors argued that the availability and pervasiveness of smart-phones in everyday life meant problematic use of the devices posed a different and much bigger public health problem than substances of abuse or internet gaming.

Kalk said the team were now looking at whether smart-phones were just delivering addictive content, or whether there was something inherently addictive about using such devices.

Dr Amy Orben, an expert in screen time at the University of Cambridge, raised concerns, noting that the definition of problematic internet use varied considerably across studies, and the measures used were questioned.

She said studies finding little signs of problematic internet use might have been overlooked, while the research could not say whether problematic smart-phone use caused poorer mental health.

Prof Russell Viner, President of Royal College of Paediatrics and Child Health, said that parents were navigating unchartered water when it came to technology.

“One of the most critical things for parents to consider is whether screen time is having a harmful impact on other activities like school, relationships or other interests. This study suggests that this is the case for a significant minority of children and young people,” he said.

Viner said in these cases parents should calmly install age-appropriate boundaries on smart-phone use, and ask questions about whether their children were experiencing other problems.

“While screen time is a new problem, part of the solution is tried and tested-open and regular conversations based on respect and trust,” he said.

1.Experts conducted the research to ______.

A.address the concern about adolescent behavior

B.prove spending time on screens is harmful in itself

C.calculate the time young people spent on smart-phones

D.explore young people’s relationship type with smart-phones

A.it involved a vast majority of participants across the globe

B.the participants were asked to report their online activities

C.researchers compared different behaviors of the participants

D.problematic smart-phone use is linked to poorer mental health

3.Which of the following might Kalk probably agree?

A.It is hard to break problematic smart-phone use.

B.Internet gaming is problematic smart-phone use.

C.Problematic smart-phone use is an addiction.

D.The research still has some limitations.

4.What’s Dr Amy Orben’s attitude towards the research findings?

A.Supportive. B.Negative.

C.Sceptical. D.Unconcerned.

5.What does the underlined part in Paragraph 16 mean?

A.Screen time is a new challenge to parents.

B.Technology is posing a threat to parents.

C.Parents are lost in the sea of technology.

D.Parents use technology to chart water.

6.According to Viner, what should parents do to solve the problem?

A.Keep track of the screen time of children.

B.Strictly prohibit children from using devices.

C.Have a sincere communication with children.

D.Evaluate the impact of screen time on children.
