6、多用于口语，只用于句末，不用逗号隔开；too 多用于口语，用于句末，要用逗号隔开；also 较正式，不用于句末；either 用于否定句，表“也不”，与 too 对应。2. 现在完成时用来表示之前已发生或完成的动作或状态，其结果和现在有联系。动作或状态发生在过去但它的影响现在还存在；也可表示持续到现在的动作或状态。现在完成时用法：表示过去发生的动作或事情，对现在造成的影响。：表示从过去开始发生的动作持续到现在，有可能马上结束，但也有可能继续下去。这种情况下动词必须具有可持续性，至少是能重复一次以上的动作。3. 基本结构：主语+have/has+动词的过去分词（p.p）肯定句：主语+have/h
7、as+动词的过去分词(p.p)（V-ed）+宾语（或者其他）.否定句：主语+have not/has not+动词的过去分词（p.p）（V-ed）+宾语.一般疑问句：Have/Has+主语+动词的过去分词（p.p)（V-ed）+宾语（或者其他）?特殊疑问句：特殊疑问词+一般疑问句（have/has+主语+过去分词+其他） 现在完成时句型：现在完成时不能单独与准确时间状语连用，（如表示过去的时间状语）如 yesterday(morning、afternoon),last(morning、afternoon）等，除非与 for, since 连用.现在完成时往往同表示不确定的过去时间状语连用如 a
8、lready（肯定，句中），yet（否定，疑问，句末），just, before, recently, still, lately, never,ever 等例如：We have seen that film before.我们以前已经看过那部电影了。.现在完成时的完成用法指的是动作发生在过去某一时刻并已结束。例如：He has turned the light off .他已把灯关了。现在完成时完成用法的特点是动作不延续，因此，该时态只能与表示不定的过去时间状语（如：already，yet，before，recently 等）、频度时间状语（如：never，ever 等）、包括现在时刻在内的
9、时间状语（如：this morning / month /year.，today 等）连用。例如：Have you found your pen ？你已经找到你的钢笔了吗 ？现在完成时的未完成用法指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。例如：He has lived here since 1978.自从 1978 年以来，他一直住在这儿。（动作起始于1978 年，一直住到现在，可能还要继续住下去。）has gone (to),has been (to),has been (in) 的区别。has gone to：表示某人已去了某地，而没有回来（去了没回）。has be
10、en to ：表示去过某地（去过已回来）。has been in：表示一直呆在某地， 常与时间段搭配（呆了很久）。Unit 1 Topic2 The population in developing countries is growing faster.一. 重点词组归纳be in/ at home在家not any more=no more不再get/be lost=lose ones way迷路call sb. up给某人打电话shopping center购物中心central park中央公园department store百货商店talk on the phone=talk by
