用法辨析
- demand的基本意思是“要求做到”“要求得到”。作“要求做到”解时,指强硬地,断然地要求; 作“要求得到”解时,指要求得到某种应该得到、必须得到或强烈希望得到的东西。demand的语气较重,含有“理直气壮的,不容拒绝的,强求的,催促的”等意味。引申可表示“想要知道,查问,盘问,质问,询问”等意思。
- demand用作及物动词,作“要求”解时,其主语通常为人,宾语可以是名词、代词、带to的动词不定式或that从句; 作“需要”解时,其主语通常为事〔物〕,宾语一般是“时间”“耐心”等抽象名词; 作“查问”解时,可接名词、wh-从句,也可引出直接引语。demand用作不及物动词时常与介词for连用,表示“要求”。
- demand后用作宾语的that从句中谓语动词用虚拟语气,其中谓语动词用动词原形者,是美式英语用法,英式英语须加should。如主句谓语动词为一般现在时或将来时时,从句的谓语动词可与shall连用。demand不直接接表示人的词语作宾语,而须用from或of短语。
- demand可用于被动结构。以带to的动词不定式作宾语的主动句不可改为被动结构,表示被动意义时可使用不定式的被动式。
- demand用作名词时的基本意思是“要求(的行为)”和“需求(的物品〔事物〕)”,表示具体的“要求”“要求的东西”时是可数名词; 表示抽象的或笼统的“需求”时则是不可数名词,但有时可用“a+ adj. ”修饰。
- 在demand后由that引起的从句中,谓语动词须用虚拟式,即用动词原形(美国用法)或should加动词原形(英国用法)。
- demand接介词for表示“对物的需求”; 接介词on表示“对某人或某物提出的要求”; 接介词in表示“所需要的”,含有被动意义。
- demand作为名词时后面可以跟介词for,表示“需求”。There is a great demand for apples.
- 注意demand作为及物动词时,其后不跟介词for。They demands more helps.

n. (名词)
