6、根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month. ①________
One idea is that sleep helps us strengthen new memories. ②________ We know that, while awake, fresh memories are recorded by reinforcing(加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.
Support is growing for a theory that sleep evolved so that connections between neurons(神经元)in the brain can be weakened overnight, making room for fresh memories to form the next day. ③________
Now we have the most direct evidence yet that he is right. ④________ The synapses in the mice taken at the end of a period of sleep were 18 percent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.
If Tononi's theory is right, it would explain why, when we miss a night’s sleep, we find it harder the next day to concentrate and learn new information—our brains may have smaller room for new experiences.
Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. ⑤________ "You keep what matters," Tononi says.
A. We should also try to sleep well the night before.
B. It's as if the brain is preserving its most important matters.
C. Similarly, when people go for a few days without sleeping, they get sick.
D. The processes take place to stop our brains becoming loaded with memories.
E. That's why students do better in tests if they get a chance to sleep after learning.
F. "Sleep is the price we pay for learning," says Giulio Tononi, who developed the idea.
G. Tononi's team measured the size of these connections, or synapses, in the brains of 12 mice.
参考答案
1、答案：are shocked
2、答案：To begin with
3、答案：be a disgrace
4、答案：what’s more
5、答案：have no evidence
6、答案：CEFGB
解析：本文是一篇说明文,主要介绍了睡眠的重要性。
①根据前一句"When lab rats are not allowed to sleep, they die within a month."可知,如果不让实验老鼠睡觉,它们一个月之内就死了。同样,人几天不睡觉,也会生病。人和动物匹配,死和生病形成对比,故选C。
②根据前一句提到的睡眠有助于帮助我们加强新的记忆,与E项(所以如果学生在学习新知识后有机会睡一觉,他们在考试中就会表现得更好)前后逻辑关系顺畅,因果联系紧密,故选E。
③根据下文中的"he"可知此处要提到一个“他的”理论,故选F
④根据下文中提到的"synapses in the mice"可知,他肯定在老鼠的身上做了实验,故选G。
⑤根据后一句提到的"You keep what matters(你记住重要的东西)"可知,大脑会把最重要的记忆保存下来,故选B。
