     If you want to deal with the association (交往) between boys and girl right, here are some "do's and don'ts"

for you to follow.

     Keep a normal and healthy state of mind (心态). It is very natural for the boys and girls to contact (接触)

each other and build up the friendship with students of the other sex. We should have more friends of the other

sex instead of one or two. We should contact the students in public instead of in secret.

     Contact students of the other sex warmly, generously and sincerely. Don't be too nervous or too shy in

contact with a person of the other sex. In that case it is very difficult for you to make a lot of friends, as no one

likes a person who is too shy to say a word. If you are too shy a person, you can contact the students with the

same interest and hobby as you. If you keep doing like that, little by little, you will find you are also as free to

express yourself as others.

     Don't fall into the ditch (泥潭) of early love. The boys and girls at adolescence (青春期) are rich in feelings

and full of imagination. They are easy to regard the friendship as a sign of love and to fall in love with each other

at an early age. In my opinion, boys and girls at middle school are too young and too tender (嫩的) to shoulder

the heavy duty of love. Early love is a green apple that can't be eaten. Do keep out of early love.

1. We should contact students of the other sex in the following ways EXCEPT _______. [ ]

A. with a good state of mind

B. in public

C. in secret

2. The underlined word "imagination" means _______. [ ]

A. 想象力

B. 幻觉

C. 梦想

3. A person at adolescence is NOT _______. [ ]

A. rich in feeling

C. old enough to fall in love

4. Which of the following is NOT true? [ ]

A. We'd better not make only one or two friends of the other sex.

B. Some students are too nervous or too shy in contact with a person of the other sex.

C. People like a person who always keeps silent.

5. The main idea of the reading is to _______. [ ]

A. tell students to keep away from early love
