现在完成时和过去完成时的区别
现在完成时是指某个动作从过去开始一直持续到现在,或对现在有影响.是站在"现在''的时间点上.如:Ihavehadbreakfast.我吃过早餐了.那么我现在就用不着再吃饭了,因为我饱了.这就是"havebreakfast''对现在的影响.过去完成时则比现在完成时往前推了一段时间,即"过去的过去''.是站在过去的时间点上.还是吃饭那句,如果我明天(或将来的任何时候)还要说这事,我就得说Ihadbreakfast(yesterdaymorning./ect...)基本词汇课标词汇词性北师大版a(an)一个a(an)art1A-02alot大量的4A-02afraid害怕的afraida5A-01after在…之后afterad/prep/conj4B-09afternoon下午afternoonn4B-09again又、再againad3A-01air空气airn5A-01am是vAmerican美国人Americana&n2A-03and和andconj2B-10apple苹果applen1A-01April四月Apriln5A-04are是v1B-11aren’t2B-08arm手臂armn3B-11art美术artn3A-05at在atprepAugust八月Augustn5A-04AuntHYPERLINK"http://zhidao.baidu.com/search?word=%E5%A7%91%E5%A7%91&fr=qb_search_exp&ie=utf8"\t"_blank"姑姑、HYPERLINK"http://zhidao.baidu.com/search?word=%E5%A9%B6%E5%A9%B6&fr=qb_search_exp&ie=utf8"\t"_blank"婶婶auntn2A-04Australia澳大利亚Australianautumn秋季autumnn5A-04baby婴儿babyn2A-01bad(worse,worst)有害的bad(worse,worst)a3B-08bag书包bagn1A-03ball球balln2A-01banana香蕉bananan1A-01bathroom浴室3A-04be(is,am,are,was,were,being,been)be(is,am,are,was,were,being,been)auxvbeat打beatv&n2B-10/4B-10beautiful美丽的beautifula3A-06bed床bedn4A-04bedroom卧室bedroomn3A-04big大的biga2B-09bike=bicycle自行车bike=bicyclen2A-05bird鸟n1B-07black黑色的blacka&n2B-10blue蓝色的adj1A-04book书n1A-01box盒子boxn4B-09boy男孩boyn1A-02bread面包nbreakfast早餐breakfastn4B-09Britain英国n2A-03brother兄弟brothern1B-10brown棕色的brownn&a1A-04bus公共汽车n4A-05but但是butconj2B-11butterfly蝴蝶*butterflyn2B-10can能v1B-12can’t不能v2B-11cap运动帽capn3B-10car小汽车carn2A-05carrot胡萝卜n2B-08cat猫catn1A-02chair椅子chairn1A-03chicken鸡、鸡肉chickenn1B-09Chinese中国的、中国人Chinesea&n3A-05Christmas圣诞节n3A-06circle圆、圆周n1B-08class班级n4B-07classroom教室classroomn3A-05climb攀爬climbv2B-11clock钟clockn3B-10close关闭closev&a4B-10clothes衣服clothesn4A-03cloudyHYPERLINK"http://zhidao.baidu.com/search?word=%E5%A4%9A%E4%BA%91&fr=qb_search_exp&ie=utf8"\t"_blank"多云的cloudya4B-11coat外套、上衣coatn3A-04cold寒冷colda&n3B-09colour(=color<美>)颜色n2B-10computer电脑computern2A-05dad(daddy)爸爸n2A-05dance跳舞dancev&n1B-12dangerous危险dangerousa4A-06day日子dayn4B-07December十二月n5A-04d
