专四语法重点题 than 连词 than 引导比较状语从句，有时省去部分谓语，保留了主语和助动词，此时助动词可以移到主语前。如： John drives much more carefully than does his father. (=than his father drives) 连词 than 引导比较状语从句，常省去主语，保留谓语部分，这种结构多见于正式文体中。如： Don’t eat more than is good for you. 倍数的表达 倍数+形容词（或副词）的比较级+than 倍数+as+形容词或副词（或 many / much） +as 倍数+the size（length，height…）of 倍数+more+名词（可数，不可数）+than 倍数+as many（或much）+名词 +as as as much as “达到与……一样的程度” not so much …as “与其说……不如说……” such as to “到如此程度以致……” no / not any more … than … “两者一样都不……” no / not any less … than … “两者一样都……” A is to B what C is to D Water is to fish what air is to man. 重要短语 no more than = only “仅” not more than = at most “至多” no / not any more … than … = neither ..nor ..两者一样都不……，和…一样不…… not more … than = less … than “不如” no less than = as much / many as “多达” not less than = at least “至少” no / not any less … than …= as … as “两者一样都……”，“与……一样” not less … than = more … than “比……更” 合成不定代词的习惯用语 something of 若干、多少、有些 anything but 并不，根本不 nothing but 只不过，只有 something like 有点像 or something 类似 Mr. Smith is an engineer or something. She is nothing but a dancer. He was anything but pleased when he heard this. no one VS. none no one只能指人，none可用于指人或物。 no one＝nobody，语气比none强，后面不接of构成的短语；none通常与of连用作主语 no one作主语时，谓语动词用单数；none后接不可数名词作主语时，谓语动词用单数；后接复数名词作主语时，谓语动词单复数均可。 No one was in the classroom. None of the money on the desk is mine. None of us speaks / speak Japanese. 讲解 用于简短回答时，none用来回答how many或how much问句；no one或nobody用来回答who问句；而nothing则用来回答what问句； – How many fish did you catch? – None. – How much water is there in the bottle? – None. – Who will go to the party? – No one. / Nobody. – What’s in your hand? – Nothing. one, the one, that that 只能代替事物，不能代替人；one 既可代替人也可代替事物。 one代替前面出现的名词表示不确指；that, the one 代替前面出现的名词，指代谈话双方都知道的事物，即“特指”。 that 不能有前置修饰语，但须有后置修饰语；one一般可有前置修饰语，也可有后置修饰语。 讲解 one, the one 都只能指代前面出现的单数可数名词，复数可数名词则用ones, the ones；that既可指代单数可数名词，也可指代不可数名词。 that代替前面提到的事物，必须是这一名词在第二次出现时有后置修饰语；如果前面提到的是复数名词，则用those来代替。 例句 I’m looking for a house.
