题目内容
15．---Your head teacher has set up a Wechat group．Could you tell____？---It is more convenient to communicate with our parents．（ ）
| A． | when it was set up | B． | why did he set it up | ||
| C． | what it is used for | D． | how did he set it up |
分析 --你的班主任已经建立了一个微信群．你能告诉我它是用来做什么的吗？
--它与我们的父母交流更方便了．
解答 答案：C．
根据Could you tell，可知本句考查了宾语从句的用法．在宾语从句中所使用的语序应该是陈述句语序，选项BD是疑问句语序，排除掉．再根据It is more convenient to communicate with our parents，和我们的父母联系起来更方便了，可知这里谈论的是它的用途，提问的话应该用what it is used for．故选C．
点评 此题考查宾语从句．考生在答题时要注意"宾语从句必须采用陈述语序"，根据上下文语境确定合适的选项．
