数词专项练习(附答案解析)一、选择题。
1.Nowadays ______of business letters are written in English.A. two thirdB. two thirdsC. two threeD. second three本题考查的知识点是分数的表达。
句意:现如今,有三分之二的商务信函都是用英语写的。
分子用基数词,而且是2,大于1,所以分母用复数,而且用序数词,因此选B. 分数表达法为:分子用基数词,分母用序数词;分子在前,分母在后;若分子大于1时,分母用复数。
2.---Good news! Bill won _____ medal in the long jump just now.---Really? That's his ____ one at our sports meeting.A. a; fourB. an; fourthC. a; fourth本题考查的知识点是不定冠词以及序数词的用法。
句意:好消息!比尔在刚才的跳远比赛中赢得了一枚奖牌。
——真的吗?那是他在我们的运动会上赢得的第四枚了。
因为Bill赢了一枚奖牌,是泛指,用不定冠词,而且medal的第一个音节是辅音,所以用a, 而后面指第四枚,应该用序数词,因此答案为C。
名词第一次出现时用a或an, 表泛指。
“第四枚”应该用序数词fourth.3.---Peter, how old is your father this year?---_____. And we just had a party for his_____ birthday last week.A. Fortieth; fortyB. Forty; fortyC. Forty; fortiethD. Fortieth; fortieth本题考查的知识点是基数词与序数词的综合运用。
