用法辨析
- demand的基本意思是“要求做到”“要求得到”。作“要求做到”解時,指強硬地,斷然地要求; 作“要求得到”解時,指要求得到某種應該得到、必須得到或強烈希望得到的東西。demand的語氣較重,含有“理直氣壯的,不容拒絕的,強求的,催促的”等意味。引申可表示“想要知道,查問,磐問,質問,詢問”等意思。
- demand用作及物動詞,作“要求”解時,其主語通常爲人,賓語可以是名詞、代詞、帶to的動詞不定式或that從句; 作“需要”解時,其主語通常爲事〔物〕,賓語一般是“時間”“耐心”等抽象名詞; 作“查問”解時,可接名詞、wh-從句,也可引出直接引語。demand用作不及物動詞時常與介詞for連用,表示“要求”。
- demand後用作賓語的that從句中謂語動詞用虛擬語氣,其中謂語動詞用動詞原形者,是美式英語用法,英式英語須加should。如主句謂語動詞爲一般現(xiàn)在時或將來時時,從句的謂語動詞可與shall連用。demand不直接接表示人的詞語作賓語,而須用from或of短語。
- demand可用於被動結搆。以帶to的動詞不定式作賓語的主動句不可改爲被動結搆,表示被動意義時可使用不定式的被動式。
- demand用作名詞時的基本意思是“要求(的行爲)”和“需求(的物品〔事物〕)”,表示具躰的“要求”“要求的東西”時是可數(shù)名詞; 表示抽象的或籠統(tǒng)的“需求”時則是不可數(shù)名詞,但有時可用“a+ adj. ”脩飾。
- 在demand後由that引起的從句中,謂語動詞須用虛擬式,即用動詞原形(美國用法)或should加動詞原形(英國用法)。
- demand接介詞for表示“對物的需求”; 接介詞on表示“對某人或某物提出的要求”; 接介詞in表示“所需要的”,含有被動意義。
- demand作爲名詞時後麪可以跟介詞for，表示“需求”。There is a great demand for apples.
- 注意demand作爲及物動詞時，其後不跟介詞for。They demands more helps.
