Read the Reading Strategy. Then read the article to get an idea of the general meaning. Which is the best summary: a, b, c or d?
(Đọc Chiến lược đọc. Sau đó đọc bài viết để có ý tưởng về ý nghĩa chung. Đâu là tóm tắt tốt nhất: a, b, c hoặc d?)
The writer’s main purpose is to explain
a why children need more sleep than adults.
b why we should always get lots of sleep.
c why our bodies feel more or less tired at different times of day.
d why some people feel more alert than others.
Reading Strategy (Chiến lược đọc)
When matching questions with texts, follow these steps:
1 Read the text to get a general idea of the meaning.
2 Read the task’s lead-in line very carefully (In which period of the day…). Then read all the options carefully.
3 Read the paragraphs of the text carefully one by one and match them to the correct option.
4 If you can’t find the answer, leave it for now and come back to it later.
HOW MUCH SLEEP DO WE NEED?
Young children need more sleep than adults and tend to wake up earlier. A typical ten-year-old needs about ten hours’ sleep.
As you reach adolescence, your body clock changes. Most teenagers need about nine hours’ sleep, but wake up later.
As an adult, you’ll need about eight to eight and a half hours’ sleep a night.
When we are much older, in our 70s and 80s, we’re less able to sleep deeply and we usually need less sleep.
OUR PERSONAL BODY CLOCK
Each of us has our own personal body clock, which makes us more alert in the morning or more alert in the evening. You might be a ‘lark’ who likes to go to bed early and get up early, or you might be an ‘owl’ who prefers to go to bed late and get up late. Or somewhere in between.
A. 6AM-9A.M. Your body is waking up. It stops producing melatonin, the hormone which makes you feel sleepy. Blood vessels are stiffer and less flexible. Your blood is thicker and stickier s and your blood pressure is at its highest, so it’s not the best time to exercise.
B. 9AM-12P.M. You’re at your most alert at this time in the morning. Tests show that short-term memory is at its best right now.
C. 12 P.M.-3 P.M. Your stomach is full and working hard after lunch. You become much less alert and probably feel a bit sleepy. More road accidents happen at this time of day than at any other, particularly involving older 15 people.
D. 3P.M.-6PM. This is a very good time to exercise. Body temperature increases in the late afternoon. Your heart and lungs work better and muscles are six per cent stronger than at their lowest point in the day. Some sportspeople believe that if you try to break a world record at this time of day, you’ll have a greater chance of success.
E. 6PM-9PM. By now you’ll be getting hungry. But don’t eat too late! In the evening, our bodies struggle to digest fats and sugars. Studies show that people will lose more weight if they have their main meal at lunchtime rather than in the evening. (But how much you eat is always more important than when you eat.)
F. 9PM-12AM. It’s getting near to bedtime. Your body temperature is falling and your body clock is telling you that it’s time for bed. Your body is producing lots of melatonin to help you go to sleep. It can o be difficult to sleep with the light on because light reduces the amount of melatonin in your body. Blue light is particularly effective at keeping us awake. And mobile phones, computer screens and flat-screen TVs emit large s amounts of blue light. So, turn off those gadgets!
G. A.M. – 3A.M. Your body really wants to be asleep. Melatonin reaches its maximum level. Your stomach has stopped working and your brain is at rest.
H. 3A.M.-6A.M. Melatonin levels are still high, and you are in deep sleep. Your body temperature is much cooler than at any other time of the day.
