Making inferences
There is extra information that the writer did not say directly in the reading. As you read, think about related information that we can infer from the reading.
1. Why is it important for us to get enough sleep？
2. How many times a day do we need to sleep？
It’s Important to Get Enough Sleep.
We are often told that it’s important to get enough sleep, but do we know why The truth is , even scientists can’t agree on why we need to sleep. However, it’s clear that the less we sleep, the worse we perform in everyday life.
Have you ever felt tired in the middle of the day, especially after lunch Actually, this is quite normal. Researchers have found that it may be healthier to sleep twice a day—a long sleep at night, and a nap in the afternoon. Even a ten-minute nap at lunchtime can allow us to work better in the afternoon.
And if we really can’t find a chance to nap, we should get a
longer sleep at night so we don’t feel tired after lunch.
Not getting enough sleep has serious effects on our brain’s ability to work. If you go without sleep, you might have problems with your memory or with your concentration. In order to concentrate at school or perform well in tests, we really need to get a good night’s sleep.
Some people have trouble sleeping , especially if they are nervous or stressed about something. Sleep experts say that it’s better not to try too hard to get to sleep, and certainly not
to keep looking at the time. To have good sleeping habits, it’s better to sleep at regular times, and to sleep in a dark and quiet environment. It’s also good not to sleep too soon after eating, or after drinking too much water.
The amount of sleep we need is different from person to person, though the average seems to be just under eight hours. Jim Steed, a sleep researcher, has a simpler way of looking at it. “Forget about facts and figures. If we feel tired in the daytime, it means we need to get more sleep. ”
1. The truth is, even scientists can’t agree on why we
need to sleep.事实上，甚至连科学家们也不能在我们为
什么需要睡眠这个问题上达成共识。
agree on 意为“在某事上达成一致或共识”，why we need
to sleep 作 agree on 的宾语。
※ Can we agree on a date？
我们能否约定一个日期？

2. Not getting enough sleep has serious effects on
our brain’s ability to work.

不熬夜是个好习惯。
have an effect on sth. 意为“对某事有影响”。

3. Some people have trouble sleeping, especially if they
are nervous or stressed about something.

6. The amount of sleep we need is different
from person to person, though the average seems to
be just under eight hours. 我们所需要的睡眠的量因人而
