Unit 3 Inventors and inventions Ⅰ.单项填空 1．—Have you ______？ —No.I had the wrong number. A．got in B．got away C．got off D．got through 解析 考查动词短语的区别。get in“插话，收割”；get away“离开；走开”；get off“下车”；get through“接通电话，完成，到达，通过”，由此可知该题的答案为D项，意思是“你打通电话了吗？” 答案 D 2．So far nobody has claimed the money______in the library. A．discovered B．to be discovered C．discovering D．having discovered 解析 考查非谓语动词作定语。句意：迄今为止，没有人认领在图书馆里发现的钱。因discover与money之间是逻辑上的动宾关系，故用过去分词作定语。 答案 A 3．There were many talented actors out there just waiting______. A．to discover B．to be discovered C．discovered D．being discovered 解析 考查不定式的被动式作目的状语。解答这类题时，一定要弄清非谓语动词和主语之间的逻辑关系。句意：在外面有许多有才华的演员等着被发现。to be discovered为不定式短语作目的状语。discover与其逻辑主语actors之间为动宾关系，且discover动作是将要发生，故用动词不定式的被动式。 |
