题型：不详难度：来源：
The space suits can be adjusted so that the team can reproduce different levels of gravity as if they________in space.| A．are | B．has been | | C．were | D．had been |
|
答案
| C |
解析
考查虚拟语气以及as if的用法。根据句中的can be adjusted，知这些队员现在还没在太空，是一个与现在事实相反的虚拟语气，故用were。句意为：这些太空服可以调节以便队员们能模仿不同级别的引力，好像他们在太空似的。
