     Sure, it's good to get along with your teacher because it makes the time you spend in the classroom

more pleasant.

     And yes, it's good to get along with your teacher because, in general, it's smart to learn how to relate to

the different kinds of people you'll meet throughout your life.

     But really, there's one super-important reason why you should get along with your teacher. When you do,

"learning bursts right open," says Evelyn Vuko, a longtime teacher who writes an education column called

"Teacher Says" for the Washington Post newspaper.

     In fact, kids who get along with their teachers not only learn more, but they're more comfortable asking

questions and getting extra help. This makes it easier to understand new material and do your best on tests.

When you have this kind of relationship with a teacher, he or she can be someone to turn to with problems,

such as problems with learning or school matters, such as bullying (欺凌弱小者). 

     As a kid in a primary or middle school, you're at a wonderful period in your life. You're like a sponge

(海绵), able to soak up lots of new and exciting information. On top of that, you're able to think about all

this information in new ways. Your teacher knows that, and in most cases, is very excited to be the person

who's giving you all that material and helping you put it together. Remember, teachers are people, too, and

they feel great if you're open to what they're teaching you. That's why they wanted to be teachers in the

first place---to teach!

     Some kids may be able to learn in any situation, whether they like the teacher or not. But most kids are

sensitive (敏感的) to the way they get along with the teacher, and if things aren't going well, they won't

learn as well and won't enjoy being in class.

A. How much the students are expected to get along with teachers.

B. How to make the time in the classroom more pleasant.

2. What does "turn to" in the fourth paragraph really mean?

A. get help from

B. take hold of

D. think about

3. According to the passage, which of the following can be inferred?

A. If you have a good relationship with your teacher, you can get more help and learn more knowledge.

B. If you find it comfortable to ask questions, you can build a good relationship with teachers.

C. If you are getting on well with your teachers, you have more problems than others.

D. If you do your best on tests, you can build a good relationship with teachers.

A. There are some students who can learn even if they don't like the teacher.

B. Having a bad relationship with teachers does some harm to your studies.

C. Teachers are excited even if you wouldn't like to accept their teaching.
