Unit2 单元重难点及作文1、exercise的用法v.不及物，意思是锻炼 如：I exercise every dayn. 锻炼a. 习题，练习，可数名词 如：she does her exercise every evening.b. 运动、锻炼，不可数名词 如：her grandfather takes/ gets exercise every morning.2、how often的用法多久一次用来询问事情发生的频率。回答用always, usually, often, sometimes, hardly ever, never, once a day, twice a week, every four years等表频率的词或短语。 如：how often do you watch TV? I watch TV twice a week.注意区别以下短语：How long多长时间答语为for+一时间。How soon将过多久，多久以后，用将来时，答语为in+一时间How many times,多少次，表示数，答次数。How far多远，问距离，答距离。3、hardly, hardHardly是adv.意为几乎不，几乎没有，almost和否定的词的组合可与hardly互换。例如：there’s hardly any meat left.=there’s almost no meat left.在构成反意疑问句时，要前否后肯，如：She hardly says a word, does she?hard既是adj.又是adv.adj.意思为困难的，硬的，如it’s hard to work out this problem.计算出这个题是很困难的。Adv.为努力地猛烈地如：we work hard.我们都努力地工作。4、drink喝v.;饮料n.;与eat有区别。eat吃v.5、want用法v.及物动词后跟名词或代词作宾语。如：She wants a red pen.后跟不定式作宾语；want to do sth.想要做某事。如I am tired, I want to have a rest.后跟动词不定式作宾语补足语。即：want sb. to do sth. 即想要某人做某事。如：her mother wants her to drink some milk every day.拓展：wants sth.=would like sth, Want to do sth.=would like to do sth.类似的还有：hel |
