You can do a few things to make homework less stressful. First, be sure you understand the
assignment. Write it down in your notebook or day planner if you need to, and don’t be afraid
to ask questions about what is expected. It is much easier to take a minute to ask the teacher
during or after class than to struggle to remember later that night! If you want, you can also
ask how long the particular homework assignment should take to complete so you can plan
your time.
Second, use any extra time you have in school to work on your homework. Many schools
have libraries that are specifically designed to allow students to study or get homework done.
The more work you can get done in school, the less you will have to do that night.
Third, pace yourself. If you don’t finish your homework during school, think about how
much you have left and what else is going on that day, and then plan your time. Most middle
students should have between 1 and 3 hours of homework a night. If it is a heavy homework
day, you will need to devote more time to homework.
No one is expected to understand everything, and maybe you need some help. The first
place to turn for help is your teacher. But what if you don’t feel comfortable with your teacher?
If you are in a big enough school, there may be other teachers who teach the same subject.
Speak to other teachers directly and you may be in luck. Sometimes it just helps to have
someone explain something in a different way. Moreover, you might also be able to get some
help from another student. If there is someone you like who is a good student, think about
asking that person if you can study together.
28. The most important thing that you should do when you get your assignment may be
________.
A. to know when you hand it in
B. to understand it and its requirements
C. to know how long it takes to complete it
D. to remember it in order to plan the time
29. If you have any free time left at school, you should ________.
A. use it to do your homework in the library
B. spend time with your friends
C. use it to understand the assignment
D. use it to make your day planner
30. When students need some help, they should ________.
A. never ask other teachers for help
B. always turn to their own teachers for help
C. ask any good students at the subject in your school
D. go to their teachers or other teachers teaching the same subject
31. The main idea of the first three paragraphs is ________.
A. to get help when you need it
B. to do homework immediately
