二.序数词
表示排列的顺序,如:first, second, third, fourth…… 序数词前一般要加the。
巧记口诀: 一二三全要变;(first, second, third) 其余都加th; th里有意外,8去t,(eight→eighth)9去e(nine→ninth); 字母f代ve(five→fifth; twelve→twelfth); ty变成tie(twenty→twentieth); 若要变化几十几,只变个位就可以(twenty-one→twenty-first)。
2. scores of/dozens of两者表示的都是虚数“很多”之意。 如: He has been there scores/dozens of times.
