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 it?” was my logical question．They responded that their moms cooked and always told them what they were doing wrong to show their caring．I was strummed. So mom's cooking and criticizing read out as “I love you”. “Then how do you say ‘I love you’ to her?” They agreed that getting good grades, followed by good 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 responses．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，and 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．
【小题1】The foreign teacher _________．

DNA is the whole “map” of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time, In1860, Mr Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”(基因) in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages . They’re written in the DNA with a special language.
In1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell﹙细胞﹚to build its parts. So far, scientists have found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word ”means, we can help to save people from several illness. So the more we understand, the more doctors will be able to do.
Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more “words” and find out more information, we will use it in the wrong way, just to make people more attractive (有吸引力的)，or stop sick people getting jobs.
