It's important to get enough sleep.
[00:06.27]Section 1 Before you read
[00:08.18]PAIRWORK
[00:09.20]Discuss the following questions
[00:10.97]with your partner.
[00:12.50]1.How many hours do you and your partner sleep
[00:16.27]every day?
[00:17.78]2.What will happen if people
[00:20.14]do not have enough sleep?
[00:22.59]Section 2 While You Read
[00:25.71]Learning strategy¹:
[00:27.60]MAKING INFERENCES³
[00:30.77]There is extra information that the writer
[00:33.14]did not say directly in the reading.
[00:35.76]As you read,think about related⁴ information
[00:39.33]that we can infer² from the reading.
[00:42.47]It's important to get enough sleep.
[00:46.85]We are often told that
[00:48.64]it's important to get enough sleep,
[00:50.95]but do we know why?
[00:52.95]The truth is,even scientists can't agree
[00:56.13]on why we need to sleep.
[00:58.19]However, it's clear that the less we sleep,
[01:01.35]the worse we perform in everyday life.
[01:04.12]Have you ever felt tired
[01:05.80]in the middle of the day,especially after lunch?
[01:08.90]Actually,this is quite normal.
[01:11.24]Researchers have found that it may be healthier
[01:14.23]to sleep twice a day a long sleep at night,
[01:17.69]and a nap⁵ in the afternoon.
[01:19.69]Even a ten-minute nap at lunchtime
[01:21.95]can allow us to work better in the afternoon.
[01:25.70]And if we really can't find a chance to nap,
[01:28.58]we should get a longer sleep at night
[01:30.76]so we don't feel tired after lunch.
[01:33.30]Not getting enough sleep has serious effects
[01:35.94]on our brain's ability to work.
[01:38.63]If you go without sleep,
[01:40.20]you might have problems with your memory
[01:42.33]or with your concentration⁶.
[01:44.64]In order to concentrate at school
[01:46.81]or perform well in tests,
[01:48.93]we really need to get a good night's sleep.
[01:52.14]Some people have trouble sleeping,
[01:54.13]especially if they are nervous
[01:55.94]or stressed about something.
[01:58.04]Sleep experts say that it's better
[02:00.15]not to try too hard to get to sleep
[02:02.93]and certainly not to keep looking at the time.
[02:06.02]To have good sleeping habits,
[02:08.06]it's better to sleep at regular times,
[02:10.74]and to sleep in a dark and quiet environment.
[02:14.08]It's also good not to sleep too soon
[02:16.69]after eating,or after drinking too much water.
[02:21.04]The amount of sleep we need is different
[02:23.41]from person to person,though the average sees
[02:26.41]to be just under eight hours.
[02:29.10]Jim Steed, a sleep researcher,
[02:31.77]has a simpler way of looking at it.
[02:34.37]"Forget about facts and figures.
[02:36.71]If we feel tired in the daytime,
[02:39.33]it means we need to get more sleep."
[02:42.75]Section 3 After You Read
[02:45.79]3a Check (√) the information that we can infer
[02:49.69]from the reading.
[02:51.25]3b In your own words,explain what the writer
[02:55.53]is saying in each paragraph.
[02:58.87]Section 4 Go For It!
[03:02.13]Discuss the questions below with your classmates
[03:05.37]and record their answers.
[03:07.83]Use the answers to write a report about sleep.
[03:12.00]Is the amount of sleep you get important to you?
[03:15.12]Do you sleep less the night before a test?
[03:18.84]Do you think less sleep affects your results?
[03:22.57]Will you now try to get more sleep each night?
[03:26.29]If you have time!
[03:27.96]In your group,list ways that help people to
[03:30.74]get to sleep or get better sleep.
