1、Unit 5 Family Activities Lesson 3 現(xiàn)在進(jìn)行時(shí),現(xiàn)在進(jìn)行時(shí),一、現(xiàn)在進(jìn)行時(shí)的主要用法 二、現(xiàn)在進(jìn)行時(shí)的標(biāo)志 三、現(xiàn)在分詞的構(gòu)成 四、現(xiàn)在進(jìn)行時(shí)的特殊疑問句的變法,現(xiàn)在進(jìn)行時(shí)的主要用法,1、表示“此刻”正在進(jìn)行的動(dòng)作 例：She is sitting under the tree. 2、表示“現(xiàn)階段”正在進(jìn)行的動(dòng)作 例：The writer is writing a new book these days. 總結(jié)：現(xiàn)在進(jìn)行時(shí)的結(jié)構(gòu)為 主語+be動(dòng)詞（am/is/are)+現(xiàn)在分詞+,3、用“現(xiàn)在進(jìn)行時(shí)”表示將來 例：I am coming. We are leav

2、ing tomorrow. 總結(jié)：表示“來來去去”的詞，如：come go leave start move arrive fly stay等，用這些詞的現(xiàn)在進(jìn)行時(shí)表示將來的動(dòng)作。,4、某些介詞短語用于“主系表”結(jié)構(gòu)中表示動(dòng)作正在進(jìn)行。 例：They are at table. =They are eating lunch now. My mother is at work now. =My mother is working now.,5、我們知道，“always”是一般現(xiàn)在時(shí)的標(biāo)志詞。但是，在某種情況下，它也可以用于現(xiàn)在進(jìn)行時(shí)。當(dāng)它用于現(xiàn)在進(jìn)行時(shí)的時(shí)候，表示一種“感情色彩”，譯為“總是”。

3、 He is always telling lies .（他總是撒謊） She is always helping others.,6、某些特殊動(dòng)詞，不能用現(xiàn)在進(jìn)行時(shí)。 （1）have當(dāng)“有”講時(shí),不能用現(xiàn)在進(jìn)行時(shí) I have two books now. （2）”belong to”(屬于），沒有現(xiàn)在進(jìn)行時(shí) The two apples belong to me now. （3）表示”心理活動(dòng)”的詞，不用現(xiàn)在進(jìn)行時(shí) I want a dog now. 可以看出，以上例子中含有現(xiàn)在進(jìn)行時(shí)的標(biāo)志詞now，但不能用現(xiàn)在進(jìn)行時(shí)。,現(xiàn)在進(jìn)行時(shí)的標(biāo)志,1、表示現(xiàn)在的時(shí)間： (now at the mo

Hurry up! The bus is coming. 4、句子中有“l(fā)ook”、”listen”時(shí)，用現(xiàn)在 進(jìn)行時(shí)。,現(xiàn)在分詞的構(gòu)成,1、直接+ing doing going standing walking playing emptying,2、去掉末尾不發(fā)音的“e”
