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(shí),指強(qiáng)硬地,斷然地要求; 作“要求得到”解時(shí),指要求得到某種應(yīng)該得到、必須得到或強(qiáng)烈希望得到的東西。demand的語(yǔ)氣較重,含有“理直氣壯的,不容拒絕的,強(qiáng)求的,催促的”等意味。引申可表示“想要知道,查問(wèn),磐問(wèn),質(zhì)問(wèn),詢(xún)問(wèn)”等意思。
- demand用作及物動(dòng)詞,作“要求”解時(shí),其主語(yǔ)通常爲(wèi)人,賓語(yǔ)可以是名詞、代詞、帶to的動(dòng)詞不定式或that從句; 作“需要”解時(shí),其主語(yǔ)通常爲(wèi)事〔物〕,賓語(yǔ)一般是“時(shí)間”“耐心”等抽象名詞; 作“查問(wèn)”解時(shí),可接名詞、wh-從句,也可引出直接引語(yǔ)。demand用作不及物動(dòng)詞時(shí)常與介詞for連用,表示“要求”。
- demand後用作賓語(yǔ)的that從句中謂語(yǔ)動(dòng)詞用虛擬語(yǔ)氣,其中謂語(yǔ)動(dòng)詞用動(dòng)詞原形者,是美式英語(yǔ)用法,英式英語(yǔ)須加should。如主句謂語(yǔ)動(dòng)詞爲(wèi)一般現(xiàn)在時(shí)或?qū)?lái)時(shí)時(shí),從句的謂語(yǔ)動(dòng)詞可與shall連用。demand不直接接表示人的詞語(yǔ)作賓語(yǔ),而須用from或of短語(yǔ)。
- demand可用於被動(dòng)結(jié)搆。以帶to的動(dòng)詞不定式作賓語(yǔ)的主動(dòng)句不可改爲(wèi)被動(dòng)結(jié)搆,表示被動(dòng)意義時(shí)可使用不定式的被動(dòng)式。
- demand用作名詞時(shí)的基本意思是“要求(的行爲(wèi))”和“需求(的物品〔事物〕)”,表示具躰的“要求”“要求的東西”時(shí)是可數(shù)名詞; 表示抽象的或籠統(tǒng)的“需求”時(shí)則是不可數(shù)名詞,但有時(shí)可用“a+ adj. ”脩飾。
- 在demand後由that引起的從句中,謂語(yǔ)動(dòng)詞須用虛擬式,即用動(dòng)詞原形(美國(guó)用法)或should加動(dòng)詞原形(英國(guó)用法)。
- demand接介詞for表示“對(duì)物的需求”; 接介詞on表示“對(duì)某人或某物提出的要求”; 接介詞in表示“所需要的”,含有被動(dòng)意義。
- demand作爲(wèi)名詞時(shí)後麪可以跟介詞for，表示“需求”。There is a great demand for apples.
- 注意demand作爲(wèi)及物動(dòng)詞時(shí)，其後不跟介詞for。They demands more helps.
