In the early 1950s, researchers found that people scored lower on intelligence tests if they spoke more than one language. Research in the sixties found the opposite. Bilingual people scored higher than monolinguals, people who speak only one language. So which is it?
Researchers presented their newest studies last month at a meeting of the American Association for the Advancement of Science. The latest evidence shows that being bilingual does not necessarily make people smarter. But researcher Ellen Bialystok says it probably does make you better at certain skills.
Ellen Bialystok said, “Imagine driving down the highway. There’re many things that could capture your attention and you really need to be able to monitor all of them. Why would bilingualism make you any better at that?”
And the answer, she says, is that bilingual people are often better at controlling their attention — a function called the executive control system.
Ms. Bialystok is a psychology professor at York University in Toronto, Canada. She says the best method to measure the executive control system is called the Stroop Test. A person is shown words in different colors. The person has to ignore the word but say the color. The problem is that the words are all names of colors.
Ellen Bialystok said, “So you would have the word blue written in red, but you have to say red. But blue is so salient(顯著的), it’s just lighting up all these circuits(電路) in your brain, and you really want to say blue. So you need a mechanism(機制) to override that so that you can say red. That’s the executive control system.”
Her work shows that bilingual people continually practice this function. They have to, because both languages are active in their brain at the same time. They need to suppress(抑制) one to be able to speak in the other.
This mental exercise might help in other ways, too. Researchers say bilingual children are better able to separate a word from its meaning, and more likely to have friends from different cultures. Bilingual adults are often four to five years later than others in developing dementia or Alzheimer’s disease.
【小題1】What’s the best title of the text?

A.Bilingual People, Smarter

D
Parties, iPods, concerts, movies, TV shows, video games, traffic. All of these things of the modern world make life entertaining and enjoyable. But our 21st-century lifestyle is also loud and, if we don’t take notice, it can have an effect on our hearing.
Most teenagers don’t think about hearing loss. But if you experience any of the following symptoms(癥狀), you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people’s expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears.
iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of its maximum volume(最大音量), and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal.
Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss.
Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it’s like working in a loud factory all day, being a maintenance(修理)person under a jet airplane or using a jackhammer(手提鉆)on a building site.
Similarly, iPod music can cause a short time or permanent(永久的)hearing damage. A loud iPod can cause a ruptured(破裂的)eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to the auditory nerves(聽覺神經(jīng))that connect to the brain. If this happens, hearing loss becomes permanent.
【小題1】Which of the following shows that you are suffering hearing loss?

A.You are interested to listen to others’ talking.
B.You have to read others’ expressions to understand them.
C.You can only understand others over the phone.
D.You always think you hear the ringing of the phone.
【小題2】 Which of the following is TRUE when you listen to music?
A.Listen at least an hour every time.
B.Turn up the volume to the highest level.
C.keep the sound lower than 60% of its highest volume.
D.Choose classical, rock or heavy metal music.
【小題3】What is the correct order of causing permanent hearing loss?
a. The eardrum is broken.
b. The auditory nerves cannot receive sounds.
c. Tiny hairs are damaged.
d. Ear buds are placed directly in the ear canal.
e. High-volume music is played over a long time.
A.d-a-c-b-eB.e-c-a-b-dC.b-c-a-d-eD.d-e-a-c-b
【小題4】This passage is mainly about      .
A.music that teenagers likeB.hearing problems caused by the loud world
C.ways that teenagers enjoy music D.dangerous modern lifestyles of teenagers.

[1]Some people's ears produce wax like busy little bees. This can be a problem even though earwax appears to serve an important purpose. Experts say it protects and cleans the ear. It traps dirt and other matter and keeps insects out. Doctors think it might also help protect against infections. And the waxy oil keeps ears from getting too dry.

[2]So earwax is good. It even has a medical name: cerumen. And there are two kinds. Most people of European or African ancestry have the "wet" kind: thick and sticky. East Asians commonly have ___________.But you can have too much of a good thing.

[3]The glands(腺體) in the ear canal that produce the wax make too much in some people. Earwax normally falls out of the ear or gets washed away. But extra wax can harden and form a blockage that interferes with sound waves and reduces hearing. People can also cause a blockage when they try to clean out their ears,but only push the wax deeper inside. Earwax removal is sometimes necessary. But you have to use a safe method or you could do a lot of damage.

[4]Experts at N.I.H., the National Institutes of Health, suggest some ways to treat excessive earwax yourself. One way to remove wax is known as irrigation. With the head upright, take hold of the outer part of the ear. Gently pull upward to straighten the ear canal. Use an injector device to gently direct water against the wall of the ear canal. Then turn the head to the side to let the water out.

[5]The experts at N.I.H. say you may have to repeat this process a few times. Use water that is body temperature. If the water is cooler or warmer, it could make you feel dizzy. Never try irrigation if the eardrum is broken. It could lead to infection and other problems.

[6]After the earwax is gone, gently dry the ear. But if irrigation fails, the best thing to do is to go to a

 health care provider for professional assistance.
