1704791892

1704791923 英文疑难详解 99.dare 的用法
1704791924
1704791925 英文的 dare 一字,可作正动词用,又可作助动词用,在下面的文句中到底是正动词呢,还是助动词? I have never dared speak to him.(我从来不敢对他说话。)I wonder how he dares say that.(他怎敢那样说呀?)请说明 dare 的用法。
1704791926
1704791927 【解答】问题中的两个句子,dare 都是作正动词用的,在 speak 和 say 之前省略了不定词的“to”,当然我们把它说成 to speak 和 to say 也是可以的。英文有些动词,有略去后接的不定词的“to”的倾向,如 help wash the dishes (饭后帮忙洗碗),go buy a ticket(去买一张票)之类都是。
1704791928
1704791929 作正动词用的 dare 有好些意思,例如:
1704791930
1704791931 I dare you to jump over the stream.(我赌你敢跳过溪流去。)dare=challenge(挑战)
1704791932
1704791933 He dared a leap.(他冒险地跳了。)dared=risked(冒险)
1704791934
1704791935 I dared his anger and told him the truth.(我不顾他生气还是把事实告诉他了。)dared=defied(不顾)
1704791936
1704791937 He dares to do everything.(他什么事都敢做。)dared=ventured(胆敢)
