        1. It's not_______ good idea to work hard for four hours without_______ break.

          A.a(chǎn); a B.the; a
          C.the; the D.a(chǎn); the

          A

          解析試題分析:句意:不休息連續(xù)努力工作四個小時,這不是一個好主意。本題考查冠詞,a/an是不定冠詞,表示泛指一個……;定冠詞the表示特指。根據(jù)句意可知,第一個空a good idea,一個好主意;第二個空的break在這里是休息的意思,without a break是一個短語。故選A。
          考點:考查冠詞。
