I was March the----he came here last year

第一个词楼主打错了吧,应该是
It was March the( A.thirty- first ,that )he came here last year
a thirty first that b.thirty-one that c.thirty first when D.thirty -one when
强调句：it is / was + 被强调部分+ that +……
他去来这儿就是三月三十一号.
2.In our student( D .two -fifths = 2/5 ) of the students are boys
a.five-seconds b.fifth-second c.second-fifth d.two-fifths
分数的表达法：分子用基数词,分母用序词,分子大于1,分母加S
加油!不明白再问!
