她每年都到国外去。

I’vebeenabroadthreetimesthisyear.

今年我已经出国三次了。2.Recently,wehavelearnedaboutthepopulationoftheworld.

population

人口，为集合名词，常被看作一个整体，无复数形式。谓语动词用单数。表示某国某城市有多少人口时，一般说hasapopulationof...或者thepopulationof…is…

e.g.Thetownhasapopulationof20000.=Thepopulationofthetownis20000.这个城镇有两万人口。表示人口“多”或“少”时，一般用large或small来表示，而不用many或few。e.g.Chinaisacountrywithalargepopulation.

中国是一个人口众多的国家。提问有多少人口时，用what而不用howmany或howmuch。e.g.What’sthepopulationofShanghai?

上海有多少人?Thepopulationoftheworld___gettinglargerandlarger.Chinaisacountrywitha______population.(多)Japanisacountrywitha_____population.(少)Ourcityhasapopulation___twomillion.What’sthepopulation___Beijing?islargesmallofof3.HaveyoubeentoanyothercountriesinAsia?have/hasbeento，表示到过某地，现在不在该地，已经回来。have/hasbeenin，表示到过，去过；或表示一段时间待在某地。have/hasgoneto，表示到某地去了，不在本地，或在去某地途中，或已经到达该地。HehasbeentoParisthreetimes.他去过巴黎三次。Theyhavebeentothezoo.

他们到动物园去了。

Hehasgonetoseeheruncle.他去看他叔叔了。I’vebeeninLondonfortwoyears.
