     It seems school children all over the world complain about their school food. Cherie Blair, the wife of

Prime Minister Tony Blair, said that she would prepare a packed lunch for her son if school dinners do not

improve. So what do students of your age eat for lunch at school?

Japan

     High schools have canteens, which serve everything from noodles to rice, but not burgers and chips.

Other children bring food from home such as cold rice balls, meat or fish, pickles and vegetables.

     Students take home a menu for the coming month containing notes on nutrition (营养) value. Twice a

year parents are invited to have a taste of the food. The class with the fewest leftovers (剩饭) at the end of

the month receives a prize.

The United States

      A typical menu from a US school is made up of a hamburger with fried potatoes or roast chicken, lettuce

and pickles, fruit and cookies. School lunches must also provide at least one-third of the daily dietary

allowances (定量) of protein, vitamin A, vitamin C, iron, calcium, and calories (卡路里).

     Australia

     Meat pies, sausage rolls and hotdogs are all traditional dishes in Australian school shops. But as the nation

pays more attention to children's health, healthier foods have started to find their way onto school menus.

     Many schools have used a traffic light system. The sale of red-labelled foods, including pastries, chocolate

and soft drinks, is served only twice a week. Healthier green-labelled foods such as sushi, sandwiches, com

and watermelon, however, are served every day.

     In some schools, students have a choice of up t0 89 foods to choose from, including popcorn and rice.

     South Africa

     Most of South Africa's schools do not serve meals at all. Classes end at 1:30 p. m. and students get their

own lunches. Many students bring food from home, usually sandwiches.

     Fast food and fried food sell the best among students, which has led to a rise in obesity among children.

But as more people began to realize the fact that being too fat may cause different diseases, some schools in

towns have led the way towards better nutrition. Now students at these schools are provided with lunches

of porridge with vegetables, such as cabbages, onions, beans, carrots and tomatoes.

It was the district track meeting, which we had been training for all seasons. My foot still hadn't healed from a(n)   36  injury. Actually I had hesitated whether or not to  37  the meet. But there I was, preparing for the 3,200-meter run.

"Ready... set..." The gun popped and off we were. The other girls ran ahead of me. I found myself limping(跛) and felt ashamed as I  38  farther and farther behind.
