例句:Please speak a little/a bit louder.请稍微大点声说话。
(1)a lot作副词短语意为“非常”时,可用来修饰动词。
例句:She has spent a lot on clothes.她在买衣服上花费很多。

the population of…意为“……的人口数量”,可位于句首作主语,用来表示某地的人口数量,其同义短语为:…has a population of。the population of…作主语时,谓语动词用单数形式。其中population作名词,意为“人口;人口数量”。表示人口“多”要用large或great来修饰;表示人口“少”时要用small来修饰。
例句:The population of India is about 1.3 billion.=India has a population of about 1.3 billion.印度大约有十三亿人口。
询问某地有多少人时,要用句型What’s the population of…? How large is the population of…?不能用how many,how much提问。
例句:What’s the population of your hometown?=How large is the population of your hometown?你家乡的人口数量是多少?
3.as far as I know
as far as I know是一个固定的表达方式,还可以说成so far as I know,意为“据我所知”。其中as far as作从属连词,意为“就……而言”,引导状语从句,强调程度或范围。
例句:As far as I know,that is highly unlikely.据我所知,那很不可能。
as far as/so far as意为“与……的距离相等,直到……为止;就……而言”。其后可接地点名词,也可引导状语从句;否定句中多用so far as。as far as常与be concerned连用,意思是“就……而言”。
