阅读下面的短文,并根据文章后的要求答题。(请注意问题后的词数要求)

     Your schooldays should be some of the best and happiest days of your life. How can you gain the most

from them, and ensure you do not waste this wonderful opportunity to learn. 

     (1) Be positive about school! Don't say things are difficult or boring. Be interested in school-life and your

school subjects. Join in lots of activities. Be quick to put your hand up. Go round the school with a big smile.    

     (2) Expect to work. School is not a holiday camp. If you are not working, you are not learning, and you

are wasting your time at school. Teachers cannot make everything enjoyable. 

     (3) Keep fit. If you do not eat a good breakfast, you will be thinking about food in class. If you go to bed

late and do not have enough sleep, you will be sleepy in class. Play some sports to keep your body strong. 

     (4) ______. Do not say you will do things tomorrow. If you get behind the class, it is very difficult to get

back in front. You cannot finish a race if you rest all the time. 

     (5) Don't be too disappointed if things sometimes go badly. Everyone fails some tests, loses some matches

and has bad days. Friends are not always perfect, and they sometimes say and do unpleasant things. Don't let

small problems seem very big and important.

     (6) Talk about problems-sometimes they are only the result of misunderstanding. Don't be too embarrassed

to ask for help. You are young. No one thinks you can do everything!

     (7) Plan your time. Don't waste life lying in bed on Saturday morning. Go and play a sport, learn the piano,

work on a project, read a book, practise English, or help someone with problems. There are always a lot of

things to do.

     (8) Set targets. If your last grade was a D, work for a C. Try to make progress bit by bit. Think of small

targets:"I will speak in class four times this week", "I will finish my project on Wednesday" or "I will get two

more marks this week".

     Follow my advice, and have a happy school-life!
