释义 | 1.about 在用作“不久就要……”解的时候后面通常接不定式,如 about to start。但也有接动名词的,如 about starting。用不定式比较普通。 about 在用作“不久就要……”解的时候不可再加表示时间的词,如不可说 about to start next morning 或 about starng at once。 2.下面各种表达方式里的 about 都作“大约”解: about ten, about a hundred, about half, about a quarter 注意 ten, a hundred, half 和 a quarter 都是明确的数或量,原来并没有“多少不定”的意思。在有“多少不定”的意思的词语前面不该用 about,如不可说 about more than ten, about less than half, about several, about some 或 about a few 等。 虽然 about three or four 和 about a dozen or so 等表达方式也有人用,但最好删去 about。 3.下面各句里可以有 at,也可以没有 at,意思并没有区别。有了 at, about 是副词,没有 at, about 是介词: I went (at) about five (o'clock). I went (at) about noon. I went (at) about midnight. I went (at) about Christmas. 这里 at 用的少,不用的多。同样地,下面两句里的 on 和 in 也用的少,不用的多: I went (on) about 18 January. I went (in) about January. at about five (o'clock), at about noon 等不可改作 about at five (o'clock), about at noon 等。 |
