How large is the population of?不能用how many，how much提问。例句：Whats 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 knowas 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。Step3.Practice根据汉语意思完成句子。1.我今天感觉好多了。Im feeling a lot better today.2.北京的人口比武汉的（人口）多很多。Beijings population is much larger than Wuhans.3.依我所见，那不是一条真狗。As far as I can see, that isnt a real dog.Step4.ConsolidationFinish the exercises below.1.
