题目内容
10．Hey，Bob！What a surprise to see you here！When ____ you ____ this city？（ ）| A． | did，come | B． | will，come | C． | did，reach | D． | will，reach |
分析 鲍勃，在这里见到你很惊喜．你什么时候到的？
解答 答案：C．
结合句意这里是表达过去的事情用一般过去时，when是疑问词，后加一般疑问句语序，到达reach，借助于助动词did构成一般疑问句，后加动词原形，故答案是C．
点评 一般过去时表示过去某个时间里发生的动作或状态；过去习惯性、经常性的动作、行为；过去主语所具备的能力和性格．基本结构：主语+谓语（动词过去式）+句子其他成分；主语+was/were+形容词/名词/介词短语+过去时间；否定形式①was/were+not；②在行为动词前加didn't，同时还原行为动词；一般疑问句Did+主语+do+其他．
