A. where B. when C. that D. until 解析：选B，when 引导时间状语从句，句意为：在最合适的时候，他将小树移植了。 （2）-----I，m going to the post office. -----_____ you’re there ,can you get me some stamps? A. As B. While C. Because D. If 解析: 虽然as和while都可表示“在……期间”，但as要与动作动词连用，而本题的“are there”是状态，不是动作，只能用while，故选B。 2. before 的用法： before的本意为“在……之前”，根据具体语境还可理解为“还没来得及/还没有……就……，趁着还没……就……，不知不觉就……，……才……”等。如： （3）The American Civil War lasted four years _____ the North won in the end . A. after B. before C. when D. then 解析：美国内战“在北方获胜之前”延续了四年，故选B。 （4）Someone called me up in the middle of the night, but they hung up ______ I could answer
