Unit 2 Growing pains【1】辨析suggest, advise, request, order (1) suggest与advise都是动词“建议”，它们后面的宾语从句都用虚拟语气(should＋v.), should可以省略。advise sb. to do sth.表示“建议某人做某事”，advise不能用suggest替换，但可以说suggest sb./one's doing sth.。 I advise that he (should) go at once. 我建议他马上动身。 I suggested going in my car. 我建议坐我的车去。 (2) request, order等动词后接的宾语从句中，也常用“should ＋ 动词原形”作谓语，should可省略。 They ordered that for every tree cut down two more be planted. 他们要求每砍伐一棵就要补栽两棵树。 (3) It is suggested/advised/ordered/requested＋从句，此时从句也常用“should ＋ 动词原形”作谓语，should可省略。 It was ordered that the army be sent to the front. 部队接到命令，他们立即要被派往前线。 名词suggestion, advice, order, request等后接同位语从句或这些词在表语从句中作主语时，从句也用“should ＋ 动词原形”作谓语，should可省略。 He agreed with my suggestion that we should change the date. 他同意我提出的更改日期的建议。 |
