[单项选择] 第一篇：The Bilingual Brain
When Karl Kim immigrated to the United States from Korea s a teenager, he had a hard time learning English. Now he speaks it fluently, and he had a unique opportunity to see how our brains adapt to a second language. As a graduate student, Kim worked in the lab of Joy Hirsch, a neuroscientist in New York. Their work led to an important discovery. They found evidence that children and adults don’t use the same parts of the brain when they learn a second language.
The researchers used an instrument called an MRI( magnetic resonance imaging) scanner to study the brains of two groups of bilingual people. One group consisted of those who had learned a second language as children.. The other consisted of people who, like Kim, learned their second language later in life. People from both groups were placed inside the MRI scanner. This allowed Kim and Hirsch to see which parts of the brain were getting more blood and were more active
A. students do better in high school than in college.
B. bilingual children will learn better in college classes.
C. mothers are good language teachers
D. it takes more time for adults to learn a second language.

Water
The second most important constituent (构成成份) of the biosphere (生物圈) is liquid water. This can only exist in a very narrow range of temperatures, since water freezes at 0℃ and boils at 100℃. Life as we know it would only be possible on the surface of a planet which had temperatures somewhere within this narrow range.
The earth’s supply of water probably remains fairly constant in quantity. The total quantity of water is not known very accurately, but it is about enough to cover the surface of the globe to a depth of about two and three-quarter kilometers. Most of it is in the form of the salt water of the oceans about 97 percent. The rest is fresh, but three quarters of this is in the form of ice at the Poles and on mountains, and cannot be used by living systems until melted. Of the remaining fractional which is somewhat less than one per cent of the whole, there is 10—20 times as much stored underground wat
A. in the center of the earth.
B. on the surface of our planet.
C. in a very narrow range of temperatures.
D. in the coastal areas of the earth.
[单项选择]Yesterday, when Lil’ Kim was sentenced to a year and a day in prison for lying to a grand jury, it seemed like more proof that rappers just can’t stay out of jail. The conventional wisdom is that for hip-hop stars, there’s a connection between crime and credibility. Every time some rapper poses for a mug shot, there is a chorus of commentators ready to declare that it’s all a publicity stunt.
The sentencing of Lil’ Kim comes after two months when two rappers faced more serious charges. On June 17 the Philadelphia rapper Cassidy turned himself in to the police, who were looking for him as a suspect in a shooting that killed one man and wounded two others. Less than two weeks later, Cassidy’s second album, "I’m a Hustla", arrived in stores; it makes its debut at No. 5 on this week’s Billboard album chart.
And in May, the emerging Atlanta rapper Gucci Mane surrendered in connection with the slaying of a rapper from Macon, Ga., named Pookie Loc; the arrest came the same day a
A. released his first album alter his arrest.
