     In many western schools, sports day is a big event. Children take part in competitive (竞争性的) sports,

trying to break school records and take the first place.

     Sports days, or sports meets, are usually held in the warmer seasons, either at the beginning or the end of

the school year. They are also called field days.

     Primary school sports days are fun. They usually have activities such as the egg and the spoon race and

the sack race. Other events include the skipping race (跳绳) and the three-legged race. In middle and high

schools, sports days include many of the common track and field events ( 田径项目). They are more serious

and competitive than primary school ones.

     Students' parents and other relatives also come to the school on sports days. They watch children play.

Many schools in the West have "mothers and fathers" races for parents to take part in! Although sports days

are exciting, they also have some problems. According to some reports in the US, sports days have become

too competitive to be good for students. Some parents put too much pressure ( 压力) on the children. Some

schools don't have  mothers and fathersn races any more as there is much fighting and cheating.
