这些不定代词大都可以用作名词,在句中作主语、宾语、表语,也可以用作形容词,在句子中作定语。 (一)some,any及其合成词的用法。 1. 基本用法 some,any可与单、复数和不可数名词连用。 通常some用于肯定句中,而否定句、 疑问句和条件句中常用any。 e.g.:I have some interesting books. There is some water in the bottle. I don’t have any money. Were there any sharks in the aquarium? If I have any apple, I will give you.2. 特殊用法 在疑问句中,一般不用some,只有当问句表示一种邀请或者请求,或期待一个肯定的回答时才用some。 e. g.:Would you like some more tea?Can you spare me some time? (二)all,both的用法 1. all代表或修饰两个以上的人或事物,或不可数的东西。 e.g.:We all like eat potato chips. All the students in our class went to the zoo. 2. both是指“两者都……” e.g.:The twins both have long hair. There are many trees on both sides of the street. (三)many,much,a lot,a few,few,a little,little这些词都可以表示数量,并且都可以修饰名词。 1. many,a lot,a few,few修饰可数名词;much,a little,little修饰不可数名词。 2. many,much,a lot,a few,a little表示肯定的意思:few,little表示否定的意思。 e.g.:How much relish do we need? There are a few minutes left, aren’t there? There is little time left, is there? II. 形容词和副词比较等级:英语中的形容词和副词,在表示“更加”和“最”这样的概念时,要用特别的形式,称为比较级和最高级。 原级 比较级 最高级 young(年轻) younger(比较年轻) the youngest(最年轻) (一)变化形式如下: 1. 规则变化 一般单音节词和部分双音节词在词尾加-er(比较级)和-est(最高级)tall great fast near 以不发音的e结尾的单音节词和少数以le结尾的双音节词只在词尾加-r和-stnice large able late “辅音字母+y”结尾的双音节词,将词尾的y改为i,再加-er和-est easy busy early重读闭音节词,只有一个辅音字母结尾时,要双写该辅音字母,再加-er,-est big hot thin 部分双音节词和多音节词,在该词前面加more和the most构成比较级和最高级important beautifulslowly quickly 2. 不规则变化 good好的(adj.) well健康的(adj.)好(adv.) better (the) best bad坏的(adj.) ill有病的(adj.) badly坏(adv.) worse (the) worst many多(adj. & adv.) much多(adj. & adv.) more (the) most far远(adj. & adv.) farther / further (the) farthest / (the) furthest little少(adj. & adv.) less (the) least old老的(adj.) older/elder the oldest/eldest late迟的,晚的(adj.) later/latter the latest / the latest (二)形容词和副词比较等级的用法。 形容词和副词比较等级通常分为原形,比较级和最高级三种基本形式,具体而言,它们分别以下列形式出现在句中: (1)as +原形+ as 表示“……和……相同”。My dog is as old as that one. The jacket is as cheap as that old one. Is he as busy as before? (2)比较级+ than 表示“……比……较为……”。
