题目内容

3．It is said that the gravity on Mars is only about __________ of the gravity on earth．（　　）

A．

three-eighths

B．

third-eighth

D．

分析翻译：据说火星上的重力只是地球上重力的大约八分之三．

解答答案：A．英语中分数的表达，先说分子数后说分母数，用基数词表示分数的分子，用序数词表示分数的分母．当分子是一时，分数的分母用单数形式，在表示分数时，当分数的分子大于一时，分数的分母要用复数形式，因此八分之三应该表达成three-eighths，故选A．

点评本题主要考查的是分数的表达，先说分子数后说分某数，分子用基数词，分母用序数词，分子数超过"1"时，分母用复数．
