1. 应该选B。句意:四川因当地的小吃而著称。
be famous as 后一般跟 人,表“做为......人而闻名”
be famous for 后一般跟事物 ,表“因/由于......而闻名”
be famous to 后一般跟 人,表“对......是熟悉的”,“为......所熟知的”
以上as, for, to都是介词。
2. 选B。buy sb. sth.“为某人买东西”。sb这儿作宾语,所以要用宾格。
3. 选C。need作为实意动词时,后要接to do sth。其否定结构为don't/doesn't/didn't need to do sth.作为情态动词时,后接动词原形,其否定形式为needn't do sth.
4.选A。spend/cost/pay/take
(1)spend的主语通常是人,往往用于以下句型:
(sb)spend some money/some time on sth.
(sb)spend some money/some time(in)doing sth.例如:
I spent fifty yuan on the coat.
= I spent fifty yuan (in) buying the coat. 我花50元买了这件大衣。
He spent three days on the work.
= He spend three days (in) doing the work. 我干这项工作用了3天。
(2)take常用于“占用、花费”时间,其主语通常为形式主语“it”或物。句式是:
It takes/took sb.some time to do sth=Sth.takes sb.some time. 例如:
It took me three years to draw the beautiful horses.
画这些漂亮的马花费了我3年时间。
The work will take me two days.这项工作花了2天时间。
(3) pay为“付款、赔偿”之意,主语通常是人,往往是sb. pays some money for sth或pay sb.(some money for sth) 例如:
I paid fifty yuan for the coat.我花50元买了这件大衣。
He has paid the doctor 50 pounds for the medicine? 他买药已付医生50英镑。
How much did you pay him? 你付他多少钱?
(4) cost的主语必须是某物。spend … on sth./in doing sth.的主语必须是人。pay … for 的主语也是人。It takes + sb.+ 时间(或钱)to do sth.的主语则必须是形式主语It。 动词cost的常用用法是sth.cost (sb.) some money。
如:The dictionary cost me £ 20.
5.是填warning。warning [ˈwɔ:niŋ]n.警告;前兆
b famous for 因什么而闻名
b buy sb sth sb用宾格her
c 没必要
分析:1.need可以作实意动词,主要用法有两个:
A need to do sth A需要去做某事(主动)
A need doing sth A需要被......(被动)
例:Mary needs to do her homework.
Your hair needs cutting.(=Your hair needs to be
cut)
注:need作实意动词,既可作及物动词,也可作不及物动词.否定形式为don't/doesn't+need+其他
例:I need it.(need作及物动词)
2.need可以作情态动词,其后直接加动词原形,否定形式为needn't/need not+动词原形,有不允许的意味
cost sth to do sth可以是时间金钱等
warning 是名词,表示警告,我个人认为应该是to be warning应该注意,tell sb sth/to do sth/be+形容词
