Having had a long day, I was too tired to greet them and then I noticed the material my daughter had used．It had been purchased to make a color-coordinated (颜色协调的) baby blanket, and now had chunks (块) cut out of almost every piece of fabric (织物)．Not stopping to listen, I exploded at the children and explained how angry I was at what had been done．

My daughter listened to me sheepishly, not trying to defend herself at all, but the pain could be seen written across her face．She retreated to her room, and spent some time there alone before she came out to say good night and once again apologized for the mistake she had made．

A few hours later, as I was preparing to go to bed, I found that there on my bed lay a beautiful, little cushion made out of the forbidden fabric, with the words “I LOVE MOM”．Alongside it was a note apologizing again, and the innocence in which she had taken the fabric．

To this day, I still get tears in my eyes when I think of how I reacted and still feel the pain of my actions．It was I who then went to her and apologized for my actions．I display with great pride the cushion on my bed, and constantly use it to remind me that nothing in this world is greater than a child’s love．

'We convince ourselves that life will be better once we are married, have a baby, then another. Then we get frustrated (使… 受挫) because our children are not old enough, and that all will be well when they are older. Then we are frustrated because they reach adolescence and we must deal with them. Surely we'll be happier when they grow out of the teen years.

We tell ourselves our life will be better when our husband/wife gets his/her act together, when we have a nicer car, when we can take a vacation, when we finally retire. The truth is that there is no better time to be happy than right now. If not, then when? Your life will always be full of challenges. It is better to admit as much and to decide to be happy in spite of it all.

For the longest time, it seemed that life was about to start-----real life.

But there was always some obstacle(挫折)along the way, a hard time to get through, some work to be finished, some time to be given, a bill to be paid. Then life would start. It finally dawned on me that that those obstacles were part of life. Little by little, that point of view also helped me see that there isn't any road to happiness.

Happiness is the road. So, enjoy every moment. And bear in mind that Time waits for no one. So stop waiting for school to end, for a return to school, to lose ten pounds, to gain ten pounds, for work to begin, to get married, for Friday evening, for Sunday morning, waiting for a new car, for your mortgage(借款)to be paid off, for spring, for summer, for fall, for winter, for the first or the fifteenth of the month, for your song to be played on the radio, to die, to be reborn… before deciding to be happy.

Happiness is a voyage, not a destination. There is no better time to be happy than… NOW! Live and enjoy the moment.'

Dear editor,

I’m a senior 3 student from Xinhua Middle School. As is known to all, senior3 students are suffering heavy pressure of study. As a result, many students are trying to spare every minute to study, even during the ten-minute break between classes.

In my opinion, taking the break is definity necessary, which makes us relaxed both physically and mentally. The ten-minute break is meant for us to relax and prepare for the next class . Only by doing so can we have more energy to study effectively in class.

My ten-minute break is always pleasing as well as relaxing. Sometimes I do some simple exercises. Sometimes I have a free chat with my classmates or just take a walk outside. Therefore, I always feel energetic and listen attentivly in class.

Yours,

Li Yue
