▲熟练掌握现在完成时态的用法及其应用。
要求学生在课前复习这三个单元、背诵课文、对话和单词，复习现在完成时态，及动词的变化形式，查看P255-257
have/has+动词的过去分词
just, already, yet, ever, never, several times
already一般用于肯定句中，而yet一般用于疑问句或否定句中 ●现在完成时态表示过去发生的动作对现在造成的影响或结果
●现在完成时态也可表示过去发生的动作一直持续到现在的动作或状态，可以和
表示从过去某一时刻延续到现在(包括“现在”在内)的一段时间的状语连用，常以for和since
for since have/has been to与have/has gone to的区别:\\= have/has been to意为“已经去过某地，且已回来”，have/has gone to意为“去了某地，但还未回来”。
此考查内容一般出现在选择题型和综合能力题型中，考生需注意句意与上下文的联系点，确定时态的正确运用。
例1：Li Lei's never been out of China, he?
A. is B. was C. has D. does

例2：-Shall we go out for a walk?

解析 此为否定句，故用yet, yet一般用于否定句或疑问句，already一般用于肯定句中。
例3：Mrs Black has had the pet Dec.25th,2001.
A. on B. since C. in D. at 解析 从表面上看此题为具体的时间，考生常误选为A，但前面运用的时态是现在完成时态，表示和现在相联系，故应选B。
例4：So far China up 135 satellites.
A. sent B. is sending C. sends D. has sent 解析 此题中so far意为“至今”，常和现在完成时态连用，答案应选D。
例5：-Mr Song Beijing.
