試題分析：考查連詞：be about to…可以和when…連用，表示“剛要做…這時(shí)…,”句意：代理剛要在文件上簽名字，這時(shí)使我驚訝的是，一個(gè)陌生人闖進(jìn)來(lái)阻止了他。A. while當(dāng)…時(shí)候，表示一段時(shí)間，C. as 當(dāng)…時(shí)候，表示兩個(gè)動(dòng)作同時(shí)發(fā)生，D. until直到，選B。
點(diǎn)評(píng)：連詞的詞義辨析要放在上下文的語(yǔ)境中進(jìn)行，要注意上下文的語(yǔ)義的串聯(lián)以及邏輯關(guān)系的推理，特別要注意一些連詞和時(shí)間狀語(yǔ)的固定搭配。When可以適用于句型：be doing…when…/be about to do …when….
