9.Sleeping in is one of the best parts of the weekend.After a long,exhausting work week,sometimes all you want to do is sleep.On Friday night,you slide under the covers,smiling in anticipation..Now you can finally catch up on your sleep.Except you can't.When you open your eyes Saturday morning,it's still early.If this were a weekday,you'd be up before your alarm.So what's the deal?
We hate to break it to you,but you've pretty much done this to yourself.Your body is very good at recognizing patterns and adjusting accordingly.If you've got a 9-to-5job,you're getting up early five days a week.This effectively sets your body clock to wake you at a certain time each day.You can shut off your alarm clock,but your body clock will just keep ticking.
There's another reason that you probably don't want to think about:You're just not as young as you used to be.We need less sleep as we get older.Babies need between 16and 20hours.Teenagers should (but often don't) get nine hours a night.Younger and middle-aged adults need eight.In general,the older you get,the harder it is to snooze the day away.
Even if you do manage to sleep in,you may never fully catch up on your sleep.If your body needs eight hours every night and you only get six or seven from Monday to Friday,you'd have to sleep an extra five to ten hours on Saturday to make it up.And experts say even that may not be enough.
The bottom line:Sleep when you can,and enjoy those extra weekend morning hours.Who doesn't want a longer weekend?
29.What does the underlined sentence mean in Paragraph 1?B
A.You know that you will oversleep on Saturday morning.
B.You needn't get up early on Saturday morning,so you will have a better sleep.
C.Since you don't work on Saturday,you needn't go to sleep as usual.
D.You know that even though you needn't get up early on Saturday morning,you will wake as usual.
30.What can we learn from Paragraph 3?B
A.If you have a 9-to-5job,you are likely to develop a flexible body clock.
B.Once you have set your body clock,it is not easy to change it.
C.The author will not break the pattern,but you will do it yourself.
D.If you adjust your body clock accordingly,you are healthy.
31.Which of the following is the reason why you can't sleep in on weekends?C
A.You are not willing to admit that you are old.
B.You need to relax on the weekend.
C.Your body clock still works on weekends.
D.You can never get enough sleep.
32.Which is the best title of the passage?A
A.Why can't I sleep in on weekends anymore?
B.Why can't I catch up on my sleep?
C.How to turn off my body clock on Saturdays?
D.How to get more sleep on Saturday mornings?
