We took quite a few photos there. Few people know what happened .There is now little hope of success. 4.由some，any，no，every构成的复合不定代词作主语时，都作单数看待，其谓语动词用单数第三人称形式。 例如Something is wrong with my watch . Well, everyone wants to win. Nobody knows what the future will be like. There is something for everyone at Greenwood Park. 5.除noone以外，其他复合不定代词都写成一个词。 6不定代词若有定语修饰，该定语要置于其后。例如: Did anyone see something good at the cinema For lunch,we had something very special -Malaysian yellow noodles Do you have anything to say Ⅱ.频度副词(Adverbs of Frequency) 频度副词表示事情发生的频率，可用来回答howoften引导的问句。常用的频度副词有always，almost always,usually,often,sometimes,hardly ever(seldom),never等，它们在频度上的差异可以这样表示: always (100%) > almost always > usually > often > sometimes > hardly ever(seldom) > never(0%) 频度副词通常放在动词前面，若句子里有情态动词、助动词或系动词be，则放在这类动词(第一个)的后面。 例如:It's always interesting to watch other people show their talents. Why do people usually make resolutions When we watch movies about the futurewe sometimes see robots. They hardly ever watch TV. Fewer people will do such jobs in the future because they are boring,but robots will never get bored. Ⅲ.形容词和副词的比较级和最高级(Comparative and Superlative Forms of Adjectives and Adverbs) 大多数形容词和副词有三个等级: 原级，即原形。2.比较级，表示“较……”或 “更……一些”。3.最高级，表示“最…..." 1.容和词比较级和最高级的构成 1)规则变化 2)不规则变化 2.形容词和副词的比较级和最高级的用法 注:在形容词和副词的比较级前，可以用much，alittle等修饰，如:much better，a little taller。 3表示在某一面相同时，用“as+形容词或副词原形+as”的句型。如: I think science is as important as math. Tom runs as fast as Jack. 表示一方在某一方面不及另一方时，用“notas/so+形容词或副词原形+as”的句型。 如: It is not as/so warm today as yesterday . He did not come as/so early as Wang Lin IV动词(Verbs) 1.动词的种类(Kinds ofVerbs) 2.一般将来 ... ...
