单项选择题
General acceptance of 3-D films may prove hard to come by, as the experience of three decades ago indicated.()
A. obtain
B. explain
C. understand
D. discern
答案
参考答案:A

本题中,come by的意思是“来临,达到”。四个选项中,obtain的意思是“达到,得到”,如:He obtained a knowledge of Latin.(他学会了拉丁文)。explain的意思是“解释,说明”;understand的意思是“懂,了解”;discern的意思是“目睹,认识”。只有A项符合题意。
