Reading & Listening
Reading
Most people sleep every night and sometimes even during the day. One question that researchers in the field of medicine have often tried to answer is why people need sleep. It appears as though there are three reasons for this. The first is that sleep improves people’s memory functions. Next, people sleep in order to conserve energy. And, finally, people sleep to flush the body—particularly the brain—of harmful toxins.
For several decades, scientists have conducted experiments focusing on sleep and memory functions. Through these experiments, they have learned that people who sleep regularly and for long enough—usually six or seven hours a night—have much better cognitive abilities and memory retention than those who fail to get enough sleep. Additionally, people who have more dreams, which occur during REM sleep, typically have better memories than those who get less REM sleep.
When people sleep, their bodies are restored, and their energy is replenished. Sleep allows a person's body to repair itself while simultaneously letting it conserve energy. When a person is sleeping, his or her body uses less energy; therefore, that individual has more energy upon awaking. This helps explain why some animals, such as bears, hibernate: They can survive on little stored energy for a long period of time.
Experiments conducted on humans have proven that, after prolonged periods of sleep, their brains have fewer toxins than when they were awake. By cleansing the brain of toxins, people can think more clearly. Moreover, after getting sufficient sleep, they feel more refreshed upon waking. This permits people to engage in everyday functions with a clear mind. Contrarily, the less sleep a person gets, the more toxins remain in that individual’s brain. As a result, the person is both fuzzy headed and less productive.

听力要点：
观点：人们为什么要睡觉这个问题，还没有弄清楚。给出三个原因。
1、REM sleep和memory是没有直接关系的，因为有些人虽然没有REM sleep，但是记性还是很好。
2、睡眠可以帮我们补充能量这句话也是不准确的，因为身体组织是从食物中获取能量，因为，人们一睡醒就要吃东西。
3、我们每个人排除的或者说是吸收的毒性物质是因人而异的，并且，试验是在少数人身上做的，所以，并不确定，睡眠是否能够消除病毒。
范文分析：
SAMPLE ESSAY
①The lecturer argues that it is unclear why people sleep. She makes three statements regarding the reasons for sleep. ②These assertions directly contradict the claim in the reading passage that there are definite reasons why people need sleep.
③First, the professor asserts that there is no correlation between REM sleep and memory improvement. Those who had little or no REM sleep did not show any difference in terms of memory in that they retained good memories. ④This refutes the reading passage's contention that people with enough sleep periods and with more dreams had better cognitive and memory skills compared to those without them.
Secondly, she emphasizes that it is inaccurate to say that our energy is restored while we sleep. Living organisms gain energy by ingesting food, a statement that is proved by the fact that they eat immediately upon waking up. ⑤This rebuts the idea presented in the reading passage that our bodies are rejuvenated during sleep because our energy is supplemented during that time.
Lastly, the amount of toxins that people are exposed to and that our bodies take in is different for every individual. In addition, the experiment was conducted under a rare sleep pattern. Hence, nobody is certain about whether sleep allows the elimination of toxins, and the theory requires more research. ⑥This challenges the reading passage’s argument that our brains get rid of toxins during sleep, a process that helps people feel more energetic after they wake up.
