Article: Any foreigner who has tried to learn Chinese can tell how hard it is to master the tones required to speak and understand.And anyone who has tried to learn to play the violin or other instruments can report similar challenges. Now researchers have found that people with musical training have an easier time learning Chinese.Writing in the online edition of Nature Nenroscieme, researchers from Northwestern University say that both skills draw on the same parts of the brain that help people discover changes in pitch . One of the study's authors, Nina Kraus, said the findings suggested that studying music "actually tunes our sensory system".This means that schools that want children to do well in languages should hesitate before cutting music programs.Dr.Kraus said.She said music training might also help children with language problems. Mandarin speakers have been shown to have a more complex encoding of pitch patterns in their brains than English speakers do.This is because in Mandarin and other Asian languages, pitch plays a central role.A single syllable word can have several meanings depending on how it is _ . For this study, the researchers looked at 20 non Chinese speaking volunteers, half with no musical background and half who have studied an instrument for at least six years. As they were shown a movie, the volunteers also heard an audio tape of the Mandarin word "mi" in three of its meanings: squint, bewilder and rice.The researchers recorded activities in their brain stems to see how well they were processing the sounds.Those with a music background showed much more brain activities in response to the Chinese sounds. The lead author of the study, Patrick C.M.Wong, said it might work both ways.It appear? That native speakers of tonal languages may do better at learning instruments. Question: What would be the best title for this passage? Options: A: Mandarin Speakers Are Smarter than English Speakers. B: Skilled Ear for Music May Help Language Study. C: Pitch Plays a Central Role in Chinese Learning. D: Schools Need to Develop Music Programs.

Read the article and select the best answer. Article: One of our biggest fears nowadays is that our kids might some day get lost in a "sea of technology"rather than experiencing the natural world.Fear-producing TV and computer games are leading to a serious disconnect between kids and the great outdoors,which will change the wild places of the world,its creatures and human health for the worse,unless adults get working on child's play. Each of us has a place in nature we go sometimes,even if it was torn down.We cannot be the last generation to have that place.At this rate,kids who miss the sense of wonder outdoors will not grow up to be protectors of natural landscapes."If the decline in parks use continues across North America,who will defend parks against encroachment ?"asks Richard Louv,author ofLast Child in the Woods. Without having a nature experience,kids can turn out just fine,but they are missing out a huge enrichment of their lives.That applies to everything from their physical health and mental health,to stress levels,creativity and cognitive skills.Experts predict modern kids will have poorer health than their parents--and they say a lack of outside play is surely part of it:research suggests that kids do better academically in schools with a nature component and that play in nature fosters leadership by the smartest,not by the toughest.Even a tiny outdoor experience can create wonder in a child.The three-year-old turning over his first rock realizes he is not alone in the world.A clump of trees on the roadside can be the whole universe in his eyes.We really need to value that more. Kids are not to blame.They are over-protected and frightened.It is dangerous out there from time to time,but repetitive stress from computers is replacing breaking an arm as a childhood rite of passage. Everyone from developers,to schools and outdoors' citizens,should help regain for our kids some of the freedom and joy of exploring,taking friendship in fields and woods that cement love,respect and need for the landscape.As parents,we should devote some of our energies to... Question: According to the passage,children without experiencing nature will _ . Options: A: keep a high sense of wonder B: be over-protected by their parents C: be less healthy both physically and mentally D: change wild places and creatures for the better

Ques: Read the article and select the best answer. Article: Is been a dream for 30 years but now the world's first flying car is set to hit the roads this year. Ever since the"Back to the Future"movies lit up our screens in the 1980s,designers have dreamt of cars that could take to the sky at the push of a button. And now pilots can order their own "roadable"plane for just PS 127,000. The plane,which has fold-out wings that span 17. 5 ft,has a range of flying distance of 460 miles and can be up to 115 mph. Back on the land,it can also travel at"highway speeds" in car mode . Fuelling the 19 ft long plane couldn't be simpler--you just drive it into a petrol station and fill it up. A spokeswoman said,"You can keep you 'light-sport airplane'in your garage. But because _ needs a short runway to take to the air,you will have to drive to your local airport,fly up to 460 miles,land,and drive directly to your destination. You will always be ready to drive or fly. " The spokeswoman added,"Never let bad weather change your trip. You call simply divert and continue on the ground until the weather clears. " There's no risk to you--This is only the chance for you to be the first at your home field to unfold your wings and fly into the future. Question: According to the text,the"roadable"plane_. Options: A: can fly at"highway speeds"in car mode B: is a kind of car with fold-out wings C: is 19ft long and 17. 5 ft wide inside D: can only travel on the highway

Ques:Read the article and select the best answer. Article: Having a child may improve a woman's memory, a new study suggests. In the study, women who were new mothers scored better on tests of visuospatial memory - the ability to understand and remember information about their surroundings--compared with women who didn't have children. The findings contradicts the old belief that women develop"baby brain" or a decline in memory and cognitive function, after they have kids, said study researcher Melissa Santiago, a doctoral student at Carlos Albizu University in Miami. "You don't have to feel that because you have kids, your memory isn't the same," Santiago said. The study was small, and the findings will have to be tested in larger groups of people, Santiago said. Previous studies on the topic have had mixed results--some showed motherhood hurts cognition, and others showed the opposite. Studies on rats show those with pups have better memory than those without offspring. Santiago analyzed information from 35 first-time mothers whose children were ages 10 to 24 months, and 35 women who had never been pregnant. Both groups scored similarly on intelligence tests. The average age of mothers was 29 and the average age of never-pregnant women was 27. To test visuospatial memory, the women were shown a paper containing six symbols for 10 seconds, and then asked to draw what they remembered. This task was repeated several times. The first time women were shown the paper, both groups remembered about the same amount. But on the second and third pass, mothers performed better than those without children, indicating that the mothers collected more information each time than the other women. Later, the women were shown a variety of different symbols, and asked to remember which ones were presented on the earlier task. Mothers did not make a mistake in this task--they remembered every symbol correctly--but those without children made one or two errors, Santiago said. Question: How did Santiago lead to the findings? Options: A: By observation. B: By comparison. C: By analyzing intelligence tests. D: By asking women questions.
