They look at their phones in bed. Then they feel tired at school the next morning. Scientists in the UK and China studied more than 3,000 teenagers in the US. The teenagers wore a small watch at night. The watch recorded their sleep. The scientists also looked at their brains and gave the teenagers some tests. The teenagers were in three groups. One group went to bed late and slept about seven hours and ten minutes. Another group slept a little longer. The third group went to bed earliest and slept longest — about seven hours and 25 minutes. The difference was only fifteen minutes. But this last group did best in the tests. Doctors say teenagers need eight to ten hours of sleep. Most of the students in the study did not get enough. "Sleep helps us remember things," one scientist said. What can you do? Do some sport in the day. Put your phone away before bed. And tonight, try to go to bed fifteen minutes earlier. 02 阅读后的题目练习 After-reading Tasks ★★☆☆☆ 必做 ／ ★★★☆☆ 选做 每题都请把原文依据抄在题目下方（一个短语或一句话就够）。答案不重要，能在文章里找到依据才重要。 A 阅读理解 Chinese instructions · choose A / B / C / D 1.

You are not alone. But a large study suggests that the habit may cost more than you think. Teenagers who go to bed earlier and sleep longer tend to do better on tests of reading, vocabulary and problem solving, researchers have found. The work was carried out by scientists at the University of Cambridge and Fudan University in Shanghai. They analysed data from 3,222 young people in the US, all part of a long-term project on brain development. Each teenager had a brain scan, sat a set of cognitive tests, and wore a Fitbit that tracked their sleep. The teenagers fell into three groups. About 39 per cent went to bed latest and woke earliest, sleeping seven hours and ten minutes a night. A second group, roughly 24 per cent, managed seven hours and 21 minutes. The final 37 per cent turned in earliest, slept longest — about seven hours and 25 minutes — and had the lowest heart rates while asleep. The differences look tiny. Yet the third group scored highest on the cognitive tests, followed by the second, while the first scored lowest. Their brain scans also showed the largest brain volumes and the best brain function. "Small differences in sleep amounts accrue over time to make a big difference," said Professor Barbara Sahakian of Cambridge, who believes that sleep helps us consolidate memories. The findings appeared in the journal Cell Reports. None of the groups reached the eight to ten hours recommended for 13- to 18-year-olds by the American Academy of Sleep Medicine. Professor Colin Espie of Oxford, who was not involved in the study, pointed to "social jet lag": on school days teenagers must get up early, so they try to catch up at weekends. He would like schools to put more emphasis on sleep health in class. So what can a student actually do? Sahakian recommends regular exercise and keeping phones and computers away late in the evening. You may not be able to move the school bell, but you can move your own bedtime — by fifteen minutes tonight.

He would like schools to put more emphasis on sleep health in class. So what can a student actually do? Sahakian recommends regular exercise and keeping phones and computers away late in the evening. You may not be able to move the school bell, but you can move your own bedtime — by fifteen minutes tonight. Q1 进阶文里的 "social jet lag" 是什么意思？用一到两句中文或英文写出来。 ★★★★☆ Q2 作者为什么用 "you can move your own bedtime" 收尾？它和全文是什么关系？ ★★★★☆ 今日战绩　做完必做，就已经很了不起了 必做完成　____ / 21 项 选做挑战　____ 项 今天用时　____ 分钟 「今天多睡的十五分钟，也是明天更清醒的自己。」——先做完，再做好，别急。 今天最想记住的一个词： 给自己写一句话： 明天的小目标： ANSWER KEY 参考答案与解析 按栏目顺序排列，和正文题号一一对应。先自己改一遍，再看「为什么」。 02 A　阅读理解（4 题） 第 1 题 B　原文：The watch recorded their sleep。前一句只说「戴着手表」，这一句才说它做什么；record 在这里是动词「记录」。 第 2 题 B　第三段写 about seven hours and 25 minutes。A 是第一组的时长；C、D 把医生建议的 eight to ten hours 当成了「实测值」，其实那是建议值。 第 3 题 C　文章最后一句：try to go to bed fifteen minutes earlier。这就是给读者的行动建议。 第 4 题 A　第三段先说 The difference was only fifteen minutes，接着用 But 一转：But this last group did best in the tests。一抑一扬，正是为了说明小改变也有大影响。 02 B　完形填空（6 空逐空解析） 第 1 空 A. late　go to bed late 晚睡，呼应文章开头；下一句说第二天累，说明是「晚」不是「早」。 第 2 空 B. phones　原文：look at their phones in bed。 第 3 空 A. recorded　record their sleep 记录睡眠（见第二段）；宾语是 sleep，只有 recorded 搭得上。 第 4 空 A. longest　原文：slept longest … and did best，两处正好对应。 第 5 空 A. hours　原文：eight to ten hours of sleep。eight to ten 后面接的一定是 hours，不是 minutes / days。 第 6 空 B. earlier　文章最后一句：fifteen minutes earlier。注意 earlier 是「提前」，不是「更晚」。 02 C　判断正误（4 题） 第 1 题 F　错。第二段说的是「英国和中国的科学家」研究了「美国的 3,000 多名青少年」。研究者的国籍 ≠ 被试的国籍，这是本期最容易踩的坑。 第 2 题 T　对。第二段先说 The teenagers wore a small watch，再说 The watch recorded their sleep，两句合起来就是这个意思。 第 3 题 F　错。7 h 10 min 是第一组；第三组是 about seven hours and 25 minutes。 第 4 题 F　错，并改正：Doctors say teenagers need eight to ten hours of sleep. 改到「8 到 10 小时」即可，不要自己补写文中没有的信息。 02 D　六选五（5 空） 答案速查 1 → B　2 → D　3 → C　4 → A　5 → E　｜　多余项 F 怎么想 多余项 F：never ... again 太绝对，文中只说睡前把手机放一边，没有要求完全不用。线索：空 1 后面在解释「为什么累」，选 B「Here is one common reason」；空 2 后面出现 The watch，前面要先引出手表，选 D；空 3 后面有 But 转折，前面先摆出「差别只有十五分钟」，选 C；空 4 前讲「需要 8–10 小时」，接 A「没有一组睡够」最顺；空 5 后面是三条建议，选 E 的设问。做六选五先看空前后的代词和名词，再看逻辑词。 03　重点单词（近义 / 反义 / 例句） 第 1 词 late 近义 delayed, slow　｜　反义 early　｜　例句 Many students go to bed late. 第 2 词 watch 近义 look at, clock　｜　反义 ignore　｜　例句 The teenagers wore a small watch at night. 第 3 词 record 近义 write down, note　｜　反义 erase, forget　｜　例句 The watch recorded their sleep. 第 4 词 group 近义 team, set　｜　反义 individual　｜　例句 The teenagers were in three groups. 第 5 词 difference 近义 gap　｜　反义 similarity　｜　例句 The difference was only fifteen minutes. 第 6 词 best 近义 top, finest　｜　反义 worst　｜　例句 But this last group did best in the tests. 第 7 词 enough 近义 sufficient, plenty of　｜　反义 lack, short of　｜　例句 Most of the students did not get enough. 第 8 词 put away 近义 tidy away, store　｜　反义 take out, leave out　｜　例句 Put your phone away before bed. 04　长难句拆解（S1–S4） S1 ★★☆☆☆ 主干　The scientists looked at A and gave B. 一个主语，带两个并列谓语。 修饰　also 是副词，不进主干；the teenagers 与 some tests 是 give 的双宾语（给谁 + 给什么）。 参考译文　科学家还观察了他们的大脑，并给这些青少年做了一些测试。 小提示　看到 and 先问一句：它连的是「两个句子」还是「两个动作」？这里连的是 looked at 和 gave 两个动作。 S2 ★★☆☆☆ 主干　The third group went to bed and slept. 先抓「谁 + 做了什么」，最高级和破折号都先放一边。 修饰　earliest / longest 是副词最高级，修饰动作；破折号后的数字是补充说明 slept longest 到底有多久，不是新句子。 参考译文　第三组最早睡觉、睡得最久——大约七小时二十五分钟。 小提示　破折号后面常是「解释、补充、举例」，翻译时保留破折号即可，不要硬凑成一句新的话。 S3 ★★★★☆ 主干　They analysed data. 五个词就把句子立住了。 修饰　from 3,222 young people in the US 是介词短语，说明「什么样的数据」；all part of ... 是同位语，前面省略了 being / who were，不是并列句。 参考译文　他们分析了来自美国 3,222 名年轻人的数据，这些人都参与了一项关于大脑发育的长期研究项目。 小提示　读不懂时，把两个逗号之间、以及 from / in / of 开头的整块先括起来丢掉，主干立刻出现。 S4 ★★★★☆ 主干　You may not move A, but you can move B. but 连接两个并列分句，重心在 but 之后。 修饰　破折号后的 by fifteen minutes tonight 把「改变」落到可执行的一小步：by 表幅度，tonight 表时间。 参考译文　你也许没办法把上课铃声往后挪，但你完全可以把自己上床的时间提前——就从今晚早十五分钟开始。 小提示　文章用这一句收尾：前一半承认现实限制，后一半给出行动。写作文时可以借这个「不能……但能……」的句式。 自己上色句 主语 Scientists｜谓语 studied｜宾语 more than 3,000 teenagers；in the UK and China 修饰 Scientists（哪里的科学家），in the US 修饰 teenagers（哪里的青少年），两个都是介词短语，不进主干。 参考译文：英国和中国的科学家研究了美国 3000 多名青少年。 05　进阶阅读（选做 2 题） Q1 ★★★★☆ 上学日必须早起、睡眠不够，只好在周末补觉，这种作息的错位就叫「社交时差」。原文：on school days teenagers must get up early, so they try to catch up at weekends。只写「周末补觉」也算答对一半。 Q2 ★★★★☆ 前一半承认学生改不了学校的上课铃声（现实限制），后一半用 but 转到自己能改的事——上床时间；再把改变缩成「今晚早十五分钟」这一小步。既回应了全文的研究结论，又给读者一个马上能做的行动。 常见失误对照 改卷 / 自测时先看这四条 1. 把「研究者在哪」当成「被试在哪」：第二段是英国和中国的科学家研究美国的青少年。 2. 数字混淆：7 h 10 min（第一组）／7 h 25 min（第三组）／8–10 h（医生建议）／3,000+（人数），先在原文圈出来再选。 3. 六选五只看意思、不看衔接：F 的 never ... again 太绝对，文中只说睡前把手机放一边。 4. 翻译时把介词短语当主干：先找「谁 + 做什么」，in the UK / in the US / at night 都可以先括起来。 —— 答案区结束 · 今天辛苦了 —— ENGLISH READING LAB · No.002 · 初一版 · 第 页 学科网（北京）股份有限公司 $
