They__________the train until it disappeared in the distance.
A. saw B.watched
C. noticed D.observed
试题答案
答案：B
提示：题考查动词同义词的辨析。因与until“直到”引导的时间状语从句连用，谓语动词必须为可延续性动词，故排除saw“看见”和notice“注意到”。此句表示“注视着”“凝视着”，用watched(keptone’s eyes fixed on)较好，而不用observed(watchedcarefully)“观察”。又如：《朗文当代英汉双解词典》中的例句：Shewatched the train till it disappeared from sight. “她凝视着火车，直至火车消失在视线外为止。”Therewere so many people in the street watching the fire that firefighters could notget close to the building.
