题目内容
7．It was problem that of the students could work it out（ ）| A． | so hard a； a few | B． | so hard a； few | ||
| C． | such hard a； few | D． | such a hard； a few |
分析 这是如此难的一个问题以至于没几个学生能够解决．
解答 答案：B 根据so，such的用法结构：so+adj+a/an+n及such+a/an+adj+n，第一个空可为so hard a 或such a hard，排除C；又根据句意问题是困难的，所以很少学生能够解答，a few 表示肯定的意思"有几个"，few表示否定意思"没几个"，故选B．
点评 考查so，such的用法区别，few表否定意思，a few表肯定意思的句意差异．
