If ?。鄞鸢福?B [解析] 主句中“get me some stamps”的動(dòng)作發(fā)生在時(shí)間狀語從句“you’re there”的過程之中, 因此應(yīng)選while表示這一時(shí)間關(guān)系(屬于while引導(dǎo)時(shí)間狀語從句的兩大基本用法之一)。注意: as有時(shí)也可用于表示主句的動(dòng)作發(fā)生在從句動(dòng)作的過程中, 但這一用法不是as引導(dǎo)時(shí)間狀語從句的主要用法, 表示主句的動(dòng)作發(fā)生在從句動(dòng)作的進(jìn)行過程中時(shí)用while更為常見, 因此B選項(xiàng)是最佳選項(xiàng)。 ?。劭碱}5] ____ the days went on, the weather got worse.
