用法辨析
- allow的基本含義一是“允許某人進(jìn)入某地”“允許某人做某事”; 二是“給予某人金錢〔時(shí)間、物品、權(quán)力等〕”。引申可表示“承認(rèn),認(rèn)為”。allow所表示的“允許”含有“有能力或有權(quán)阻止卻默許、放任、不加阻止”,而“允許”其發(fā)生的意味。
- allow主要用作及物動(dòng)詞,可用于被動(dòng)結(jié)構(gòu),作“允許進(jìn)入”解時(shí)其后可直接接表示方向的副詞或介詞,作“允許做某事”解時(shí)其后可直接接賓語,也可接雙賓語,其間接賓語可轉(zhuǎn)化為介詞to的賓語,還可接以動(dòng)詞不定式(短語)作補(bǔ)足語的復(fù)合賓語。
- allow作“允許”解時(shí),其被動(dòng)結(jié)構(gòu)可以以人作主語,也可以以動(dòng)名詞作主語。作“給予”解時(shí),可以以人作主語,也可以以物作主語。
- allow作“承認(rèn)”“認(rèn)可”解時(shí)則可以接that從句或以“to be+ n./adj. ”充當(dāng)補(bǔ)足語的復(fù)合賓語。
- allow of作“許可”或“留有余地”解,其客體常由介詞of引出,多用于否定的非人稱結(jié)構(gòu)。
- allow作“考慮到”或“照顧到”解時(shí),也是不及物動(dòng)詞,其客體常由介詞for引出,主語只能是人。
- allow在法律用語中可直接接claim表示“承認(rèn)…正當(dāng)”。
- 在美式英語中, allow還可作“說”或“聲稱”解。
v. (動(dòng)詞)
