题目内容
20.-Can I continue with the training,Sir?-Sorry,you can't you haven't recovered from the knee injury.( )
| A. | until | B. | before | C. | because | D. | unless |
分析 ---我可以继续训练吗,先生?---对不起,你不能,因为你的膝伤还没康复.
解答 答案C.until直到,引导时间状语从句;before在…之前,引导时间状语从句;before因为,引导原因状语从句;unless除非,引导条件状语从句.句子在"you can't"之后省略了"continue with the training",属于语义承前省略.横线前后两句之间是逻辑上的因果关系,故答案选C.本题A选项具有很大的干扰性,会把它看成"not…until…"句型,但此时句子的意思不通顺,如果选A,应该把句子改写成"you can't until you have recovered from the knee injury."
点评 本题考查从属连词的用法.连词的用法辨析,要注意分析主从句之间的逻辑关系,再确定相应的连词,同时注意不同的连词的语义及用法区别.
