1.My brother will take part in ( ).A.the boys'300 meter race
B.the boys'300-meters-race
C.the boys'300-meter race
D.the boy's 300-meter-race
答
楼主选C，这种题有两种答案，首先是“男子比赛”，不止一个男子参赛，所以boy先加s变复数,再加'表示所有格，即boy's。然后要么是300-meter race，要么是300 meters race，所以只能有两种形式 the boy's 300-meter race或者the boy's 300 meters race
答
C.the boys'300-meter race
