高中英语知识点总结选修6Unit4核心单词oppose
高中英语知识点总结选修6Unit4核心单词oppose
as opposed to (表示对比)而,相对于易混辨析
oppose/object/resist
oppose 为常用词,指“对某人、某事采取积极行动来反对”,强调动作,尤指“反对一种观念、思想、计划等”。
object 常指“用言论或论据等表示反对”, 强调“个人嫌厌”和“由于与个人有关,因此提出反对意见”。
resist指“积极地反抗、对抗”;“用武力阻止……的前进”。
高手过招
单项填空
The professor, out the project, made a comment on the report.
A. was opposed to carry
B. opposed to carry
C. opposed to carrying
D. opposed carrying
解析:选C。
短语be opposed to sth./doing sth.意为“反对/某事/做某事”,其中to是介词。
此处用过去分词作后置定语,相当于定语从句 who was opposed to carrying。
