     Have you realized that time has passed very quickly since you entered Grade Nine? Maybe

you think you have so much homework to do every day but you do not have enough time. All

the holidays are far away, so you may feel very upset. However, you needn't be upset.There

are some ways for you to save time and cheer up.

     1. Do less. Please remember: if you want to do everything in one day, you can do nothing

well. So you'd better make a list of things you need to do first, and then decide which things are

the most important, and then put all your energy and time into them.

     2. Don't meet other people too often. Not all meetings will waste your time, but many will.

You should say no to your friends sometimes when they invite you to do outdoor activities. If you

always say yes to those invitations, it may mean that you are giving up your own time and that you

can't do the things you need to do.

     3. Don't make long conversations. You may have one or two close friends in your school

and they may be good at chatting. If you don't want to waste time, you'd better try not to have a

long conversation with them. You should learn how to spend your time.

1. The writer tells us to do _____ first in one day.

A. the most important things

B. the most difficult things

C. as many things as we can

D. something interesting

A. you need to study with friends

C. do outdoor activities with your friends

D. you'd better have a short conversation with your close friends
