Do you know what school life is like in Singapore? In Singapore, a class only lasts half an hour, but there are no breaks between classes. The students only have a 30-minute tea break after 3 or 4 classes.

They do not do eye exercises. Yao Suyu said our eye exercises were unfamiliar(不熟悉)to her. “I’d like to introduce them to our school,” she said. “They’re very useful!”

In Singapore school ends at 1:50 p.m. But students joined other classes after school such as dance clubs and choir(合唱团). Yao says she joins dance club twice a week and it lasts from 1:30 to 5:30 p.m.

Singapore’s population(人口)includes Chinese, Indians(印度人), Malays(马来人 )and Westerners. But there is no special school for any one of the groups. The students in Yao’s school are mainly Chinese, Indians and Malays. “The Indian students take Indian language classes when we study Chinese,” said Yao. “But if an Indian student is interested in Chinese, he or she can study it, too.”

In Singaporean schools, teachers teach in English. It’s the official(官方的)language in Singapore. Singaporean students have to take different courses after school. Like most Singaporean students, Yao took other courses in Chinese, math and English.
