语法提要】lot
a lot意为“很;非常”,在句中用来修饰形容词的比较级bigger,表示“……得多”。在比较级结构中,为了强调形容词或副词的程度,可在其前用a lot,a little,a bit,much,even,any,still等副词(短语)修饰。
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。
2)a lot of=lots of意为“许多;大量”,既可修饰可数名词,相当于many,也可修饰不可数名词,相当于much。
例句:there were a lot of/lots of people in the cinema.电影院里有很多人。
population of
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?
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”。
例句:alan will go with you as far as london.艾伦将与你同行到伦敦。
as far as the weather is concerned,i do not think it matters.至于天气,我认为无关紧要。
根据汉语意思完成句子。
1.我今天感觉好多了。
i’m feeling a lot better today.
