Scientists have proved that sleeping and learning go hand in hand. Even a short nap can boost our memory and sharpen our thinking. But the relationship goes deeper than that.

“The brain is not passive while you sleep,” scientist Anat Arzi said. “It’s quite active. You can do many things while you are asleep.”

Arzi and her coworkers didn’t try to teach the sleeping volunteers any complex information, like new words or facts. Instead, the scientists taught volunteers to make new connections between smells and sounds.

When we smell something good, like a flower, we take deep breaths. When we smell something bad, we take short breaths. Arzi and her co-workers based their experiment on these reactions.

Once the volunteers fell asleep in the lab, the scientists went to work. They gave them a whiff of something pleasant and meanwhile played a particular musical note. They didn’t wake up, but they heard—and sniffed(吸气) deeply. Then the scientists gave the volunteers a whiff of something terrible and played a different musical note. Again, the volunteers heard and smelled—a short snort this time—but didn’t wake up. The researchers repeated the experiment.

After just four repetitions, volunteers made a connection between the musical notes and their paired smells. When the scientists played the musical tone that went with good smells, the sleepers breathed deeply. And when the scientists played the musical tone that went with bad smells, the sleepers breathed briefly—despite there being no bad smell.

The next day, the volunteers woke up with the sound-smell connection. They breathed deeply when hearing one tone and cut their breaths short when hearing the other, which must have been unusual for them. Imagine walking down the street and taking a deep breath upon hearing a particular sound!

1.In the study, the volunteers were taught _______.

A. to become active during sleep

B. to tell the difference between smells

C. to learn new words and scientific facts

D. to make sound-smell connections

2.How did the volunteers react when smelling something nice and hearing musical notes?

A. They took a deep breath.

B. They had a wonderful dream.

C. They woke up at once.

D. They took a short breath.

3.When the volunteers woke up the next day, they_______.

A. learned how to play to musical tones

B. forgot what happened during their sleep

C. continued with the sound-smell connection

D. changed their reaction when hearing the sound

4.The passage mainly tells us _______.

A. special smells and sounds can improve our memory

B. our brain can actually learn something new during sleep

C. the volunteers will always hear similar sounds on the street

D. our brain can tell the difference between smells during sleep

People who are slightly overweight or mildly obese(肥胖的) have a lower risk of early death than normal weight individuals(个人;个体), according to a new analysis of nearly 100 international studies.

The studies, most conducted within the past decade, included about three million adults from around the world. The result of these studies by researchers at the National Center for Health Statistics in Maryland, part of the U.S. Centers for Disease Control and Prevention, shows that slightly overweight or obese people were six percent less likely to die from all causes compared to people of normal weight. But the researchers found that seriously obese individuals were still at a 30 percent greater risk of death compared to healthy-weight individuals.

Study lead author Katherine Flegal says she was not surprised that overweight people would not have a higher death risk. “Because we'd actually already read a lot of this literature and realized that death rates for overweight would be at least not higher than normal[weight," she said. “I guess l was a little bit surprised that it was definitely lower. And l was also surprised that the lower rates of obesity didn't seem to differ from normal weight."

But Flegal stresses the difference in death rates appear to be small between normal-weight people and overweight and mildly obese individuals.

The finding by Flegal and colleagues have raised new questions about the reliability(可靠性)of the so-called "body mass index" or BMI, a measurement of body fat as a ratio(比例,比率)of height to weight, that has become popular in recent years among public health experts to measure potential health risks.

But Heymsfield warns that individuals should not conclude that it's okay to put on extra kilograms, since being at a healthy weight lowers the risk for heart disease and diabetes.

1.Katherine Flegal feels surprised at the fact that____.

A. obese people have higher death rates

B. slightly obese people have lower death rates

C. obese people tend to die early

D. death rates have nothing to do with body weight

2.What do we learn from the fifth paragraph?

A. BMI may not be so reliable.

B. The study provides further evidence for BMI.

C. BMI tells nothing about potential health risks.

D. BMI has been much questioned recently.

3.What can we conclude from the passage'?

A. It's OK to put on extra weight.

B. It doesn't matter if you are slightly obese.

C. Obese people are much healthier.

D. Body weight has nothing to do with death rates.

4.What topic does the passage mainly deal with?

A. Technology. B. Dieting. C. Health. D. Death.
