1.【2018·北京】1. —Hi, I’m Peter. Are you new here? I haven’t seen you around?
—Hello, Peter. I’m Bob. I just _________ on Monday.
A. start B. have started C. started D. had started
【答案】C
【解析】考查时态。句意：——嗨，我是彼得。你是新来的吗？我没有在附近见过你。——你好，彼得。我是鲍勃。我周一刚刚开始住在这儿。根据两人谈话内容可知，Bob现在在这儿，他开始(start)住在这儿是发生在周一的事情，周一是一个过去的时间，故该句应用一般过去时态，C选项正确。
点睛：一般过去时表示过去某个时间里发生的动作或状态或过去习惯性、经常性的动作、行为。一般过去时常与表示过去的时间状语或从句连用，如：yesterday，last week，in the past，in 2017，once，a few days ago等。
