Question

________ got on the train when it started to move.

A．Scarcely I had

B．Scarcely had I

C．No sooner I had

D．No sooner had I

Answer 1

D

试题分析：考查倒装句：scarcely/hardly had Sb done when….,No sooner had  sb done than….一….就….,因为连词是than，所以选D，句意是：我一上火车，火车就开了。选D。
点评：这种倒装句重点是搭配：scarcely/hardly 后面搭配when，No sooner 后面搭配than….不能混淆，还有倒装的时态是过去完成时。
