Step Ⅰ Warming-up
Lk, read and find.
(1) Shw sme grups f sentences t the Ss. (Each grup has tw sentences: ne is a sentence that uses the past simple, the ther is a sentence that uses the present perfect.)
(2) Ask Ss t wrk in grups and find what the differences are between the tw kinds f sentences, pay attentin t the wrds in red.
设计意图：通过读句子，观察句子之间的区别，引出今天要学习的语法知识。
Step Ⅱ Presentatin
Language practice
Shw the sentences in Language practice and Ss read them alud.
T: Read the sentences individually, and pay attentin t the expressins in red.
Grammar

现在完成时表示动作或状态从过去某一时刻开始、一直持续到现在，多与“since + 点时间”或“fr + 段时间”连用。fr表示“经过(一段时间)”，而since表示“自从(……以来)”。 常见结构如下：
fr + 表示一段时间的状语
一段时间+ ag
since + 表示过去的某一时间点
从句
在对现在完成时的时间状语进行提问时，我们常用hw lng。
英语中有些动词的意义不能持续，表示的是一瞬间就结束的动作，这些动词被称为非延续性动词或短暂性动词。
常见的有 cme, leave, g, lse, see, begin, start, arrive, becme, die, buy, brrw, clse, jin, reach, fall, get up 等。这类动词可以用于完成时态，但在肯定句中不能与表示动作延续的时间状语 fr 或 since 短语连用。
如果要与表示动作延续的时间状语 fr 或 since 短语连用，并用于肯定句中，就需要把非延续性动词改为延续性动词。上面的句子可改为He has been back fr three days.
设计意图：帮助学生总结语法知识，便于系统掌握。
