Most get about seven. / The reason is not laziness. During deep sleep, the brain moves what you learned during the day into long-term memory. It also clears waste products that build up while you are awake. Cut sleep, and both jobs are done badly. / Mood is affected too. A tired brain reacts more strongly to small problems. In one study, students who slept five hours for a week rated ordinary events as more stressful than students who slept eight. / Exercise helps, but timing matters. A run in the morning makes you more awake during the day and sleepier at night. A hard training session at ten in the evening can keep you awake for hours. / Screens are another problem. Bright light tells the brain that it is still daytime, so it releases less melatonin. / The good news is that sleep can be trained. A regular bedtime, a dark room and no phone for half an hour before bed will change most people's nights within two weeks. 任务一：单项选择 1.What does the brain do during deep sleep? A.It moves learning into long-term memory. B.It stops working. C.It grows new eyes. D.It stores food. 2.Why can a hard training session at ten at night be a problem? A.It can keep you awake for hours. B.It makes you hungry. C.It wastes time. D.It is dangerous. 任务二：判断正误(T/F) 3.Students who slept five hours rated ordinary events as more stressful. (　　) 4.Bright light increases melatonin. (　　) 任务三：简答 5.What three things will change most people's nights within two weeks? _______________________________________________________________________________________________ Passage2（课外同源：运动之后的两个小时） 　　Everyone knows that exercise is good for the body. Less well known is what it does to the mind. / When you exercise hard, the body releases endorphins, chemicals that reduce the feeling of pain and produce a sense of calm. This is why a runner can feel cheerful after a difficult run. / Exercise also lowers cortisol, a hormone linked to stress. In one experiment, students who walked quickly for thirty minutes before an exam had lower cortisol and felt calmer than students who sat quietly. / The effect does not last all day. Most studies find a window of one to three hours when mood and concentration are better. That makes exercise a useful tool before a test or a difficult conversation. / Nothing about it needs to be expensive. Walking, cycling, skipping and dancing all work. The best exercise is the one you will actually do again tomorrow. / “You do not need to become an athlete,” one doctor says. “You need to move, and then notice how you feel.” 任务一：单项选择 1.What do endorphins do? A.They reduce the feeling of pain and produce calm. B.They make people sleepy. C.They raise stress. D.They weaken muscles. 2.How long does the mood effect usually last? A.One to three hours. B.All day. C.Ten minutes. D.One week. 任务二：判断正误(T/F) 3.Lowering cortisol is linked to feeling calmer. (　　) 4.Exercise must be expensive to work. (　　) 任务三：简答 5.What does the doctor say you need to do? _______________________________________________________________________________________________ 任务四：单元微写作 学校健康周请你写一份“情绪自救清单”，不少于6句话。请写清三条具体做法和理由，并用上 release stress 和 regular。 _______________________________________________________________________________________________ _______________________________________________________________________________________________ _______________________________________________________________________________________________ 参考答案 夯实基础 一、单词汉译英 1.brain 2.emotion 3.hormone 4.sleep 5.memory 6.stress 7.exercise 8.development 9.affect 10.regular 11.recover 12.concentrate 二、短语汉译英 1.brain development 2.lack of sleep 3.keep a regular routine 4.release stress 5.concentrate on 6.recover from 7.be bad for 8.scientific research 三、词形变换 1.development 2.effect 3.recovery 4.concentration 5.response 能力进阶 一、单句填空 1.develops 2.affects 3.releases 4.recovered 5.need 二、根据汉语意思完成句子 1.until 2.affects; memory 3.release; stress 4.hours; sleep 5.regular; important 三、句型转换 1.How; many 2.What; a 3.Does; affect 4.is; it 5.is; studied 四、选词填空 1.brain 2.emotion 3.hormone 4.routine 5.recover 五、情景补全对话 答案：1.A 2.B 3.C 4.D 5.E；多余项：F 拓展提高 Passage1 任务一：1.A 2.A 任务二：3.T 4.F 任务三简答：5.A regular bedtime, a dark room and no phone for half an hour before bed.

First, I go outside and walk fast for twenty minutes, because exercise releases stress and makes my thoughts slower and clearer. Second, I write three sentences about what happened, which stops the same thought from going round and round. Third, I keep a regular bedtime, because everything feels heavier when I am tired. I also tell one person, usually my cousin, so the problem does not stay only in my head. None of these steps removes the problem. They simply make me strong enough to deal with it. 学科网（北京）股份有限公司 $
