历年真题考点
oppose
oppose可以用来表达不同的意见或表示反对,如托福听力中的这句:In fact, with artists in particular, you have lots of artists who support and who have benefited from this agency, although it seems that just as many artists oppose the government agency being involved in the arts.(事实上,尤其是艺术家,有很多艺术家支持政府机构介入到艺术中去并且从这一机构中获益,尽管似乎也有许多的艺术家反对这一做法。)
从上面的句子中,可以看出和oppose相反的单词是support,即“支持”。在写作或口语中要表达观点时,就可以用上这两个词。
