用法辨析
- focus用作名詞時(shí)原始意義是“火爐”,引申?duì)?wèi)“焦點(diǎn)”,轉(zhuǎn)化爲(wèi)動詞則爲(wèi)“(使)聚焦”,“(使)集中”。即“調(diào)整…的焦點(diǎn)或焦距以便看清”,引申則表示“使(注意力等)集中於某物”。
- focus用作及物動詞時(shí),可以接望遠(yuǎn)鏡、焦點(diǎn)等作賓語,也可以接陽光等作賓語,還可以接目光等作賓語。focus用於比喻作“致力於”解時(shí),則可以接mind, attention等作賓語。
- focus也用作不及物動詞,這時(shí)常和介詞on連用,表示“聚焦於…”“致力於…”等。
- focus on sth表示“集中於某事”;
- focus作“中心,焦點(diǎn)”的解釋時(shí),用詞範(fàn)圍很廣,常被濫用,需注意。
