2. There were many people present and he appeared only for a few seconds, so I only caught a ____ of him.
(A) glance (B) glimpse (C) look (D) sight
2.本题的答案是(B)
(A)glance："匆匆看，扫视"，指突然、迅速、短暂地看某人或某物。如： She took aglance at the report (她看了一眼那份报告)。glance作名词时通常后接at。此处与句意略有出入，故(A)应排除。(B)glimpse："一瞥，瞥见"，也指短暂、突然地看，作名词时后接"of"，而且在前可加不定冠词"a"，这与题意完全吻合，故应选(B)。(C)look："看"，这是四个备选答案中最常见的词，后接at，故(C)应排除。(D)sight："视力;望见"，通常指看见某人或某物，"catch sight of"是固定搭配，意为"看清某人或某物"，但在sight前面没有不定冠词"a"，故(D)应排除。
