Encouraging your high school student to do his/her best isn’t as hard as you may think. It does take time and effort, but it should become part of a daily routine that both you and your teen can enjoy more than dread （担忧）. Here are some tips that can help you.
1.   1   Know what classes he/she is taking, what your teen thinks of the teacher and/or ask if your teen feels he/she is learning anything. This is excellent dinner table conversation if you can keep it light and positive.
2. Set the expectations.   2   You would not do your teen any favors by not telling him/her what grades you will be expecting. Send a clear message to your teen about the grades you expect to see in each class.   3   Keep your expectations in line with what your teen feels he/she can do.
3.   4   While your teen will need to keep his/her goals in line with your expectations, he/she may have a goal that he/she feels is important too. Learning to establish goals teaches independence, one of the things your teen needs to learn to become a successful adult.
4. Have what they need at home, or a way to get it.   5  Your family should have library cards and a way to access the Internet for homework. Without these things, your teen could be at a disadvantage. It is also a good idea to set up a mobile homework center.
Finally, don’t forget to praise your teen for a job well done.

A．Help him/her establish goals.

B．Talk to your teen about school.

C．Learning in a classroom is a two-way street.

D．Resources are important for high school students.

E. Teens need a clear map of what you want them to do.
F. Set a good example and show him/her your love of learning.
G. Set consequences for poor grades as well as rewards for good grades.
