[誤] The Chinese football team beat the Japanese team, and is qualified to play in the half-finals.
[正] The Chinese football team beat the Japanese team, and is qualified to play in the semifinals.
注:semi- 是英語里的一個前綴,表示“半”,例如:automatic 是“自動的”,那么 semiautomatic 就表示“半自動的”;diameter 指“直徑”,那么 semi diameter 就指“半徑”;monthly 指“月刊”,那么 semi-monthly 就表示“半月刊”。以上這些都跟 semifinal(半決賽)一樣,是約定俗成的。
