the girl who sat next to me was very nervous,she______before.(她从未飞过）
问题描述：
the girl who sat next to me was very nervous,she______before.(她从未飞过）
答
答案：had never flied
从the girl who （sat） next to me was very nervous中的sat，可以看出后面的时态是要用过去的过去，即had+_____
又fly(飞)的过去式是(flied)因此用had never flied
答
had never flown
前面是一般过去时，如果后面句子里再用完成时的话，就必须要用（一般过去时再向前推一个）过去完成时了。
要记住fly的变化形式：
fly—flew—flown
答
had never flied
答
has nerve flied
