问题描述：
_my seat belt,I started the hovering carriages which carried me into what looked like a large marke
A what B that C if D whether
选项错了 应该是 Afastening B being fastened C to fasten D having fastened
答
选择D,句意为：系好了安全带,盘旋的客车载着我进入了一个像是大商场的地方.
车是在系好安全带之后才开的,所以排除现在进行时fastening,to fasten在这里表示目的,为了什么...:所以排除C,而此题目应该是现在完成时态,根据句意应该选择D.
