     When I was a foreign teacher in China, every day I taught English to my students and they taught me    about China. One day the topic turned to saying "I love you". I was shocked to learn that not one of my    students had said  this to their mothers, nor had their mothers said it to them.  "Does your mom love

you?" "Of course "they answered.

     "How do you know? "was my logical question. They responded that their mons cooked and

always told  them what they were doing wrong to show  their caring. I was stunned. So mon's cooking

and  criticzing read out as "I love you ".  "Then how do you say 'I love you 'to her?" They agreed that

getting  good grades, followed by god jobs would be how they showed their love.

     I come from a culture where most people are expressive enough, so I repeated these queries in

classes over time. Gradually, I began to get different response. Some of them had exchanged those

sentiments with their moms.

     One of my favorite stories of change came from a girl.  When she came home from university,

her mother met her at the door and hugged(拥抱)her. This had never happened before, but her mom

said,  "Now that you have gone I have more time to myself. I noticed that in some places mothers and

children   hug each other and I decided it was a good idea and that I would begin hugging you. "

     In my family we all say "I love you" a lot. While it is true that we often say the words without

having  great depth of feelings at that moment, it is almost like a blessing we give each other.  Those three

little words carry a world of meaning, even when said as a greeting, but most especially if they are the

last  words we say to or hear from those we love.

A.  comes from America

3. In paragraph 4, what's the real meaning of the mom's hugging?

A.  She is meeting her daughter at the door.

B.  She loves her daughter and misses her.

C.  She is glad that she has more time  to herself

D.  he finds it interesting to hug her daughter.

4. What's the main idea of the passage?

A.  Say "I love you"more to your family.
