表示“几点差几分”用介词to, 但分数须在半小时以上。例如: twenty to nine, five to eight, a quarter to ten 表示“几点几分”还可直接用基数词。例如: seven fifteen, eleven thirty, nine twenty 2.序数词的用法 (1)序数词主要用作定语,前面要加定冠词,例如: The first truck is carrying a foot baskets. John lives on the fifteenth floor. (2)序数词有时前面可加不定冠词来表示“再一”,“又一”这样的意思,例如: We'll have to do it a second time. Shall I ask him a third time? When I sat down,a fourth man rose to speak. (3)由几个序数词和基数词在拼写时不对应,很容易写错,应特别注意。它们是:one---first, two---second, three---third, five---fifth, eight---eighth, nine---ninth, twelve---twelfth。 (4)表示年,月,日时, 年用基数词表示,日用序数词表示。例如: 1949年十月一日读作: October (the) first, nineteen sixty 2004年九月十日读作:September (the) tenth, two thousand and four (5)表示分数时,分子用基数词表示,分母用序数词表示。分子大于1时,分母加-s。例如: three fourths, one second, two fifths (6)序数词有时用缩写形式: first→1st second→2nd third→3rd fourth→4th twenty-second→22nd (责任编辑:admin) |
