1、-现在进行时 结构及 专项练习-第 5 页现在进行时1. 定义：现在进行时表示正在发生或进行的动作。结构是：be(am,is,are)+动词现在分词形式。 （简写： be+动词-ing）A、陈述句(肯定句)主语be(am,is,are)+现在分词，如：IamreadingEnglish.我正在读英语。Heiswriting.他正在写字。B、一般疑问句Be(Am,Is,Are)+主语现在分词，如：Areyousinging?你正在唱歌吗？C、特殊疑问句疑问词be(am,is,are)主语现在分词Whatareyoudoing?你正在干什么-Iamdoingmyhomework.我正在做作业。2.
2、标志词：(1)时间状语now、atthemoment(2)句前有提示词look、listen、lookat3.动词-ing的构成规则（1）一般情况下，直接加ing，如：cook-cooking（2）以不发音的e结尾，去e加ing，如：make-making,taste-tasting（3）如果末尾是一个元音字母和一个辅音字母，双写末尾的辅音字母，再加ing，如：run-running,stop-stopping（4）以ie结尾的动词，先把ie变成y再加-ing。 lie- lying tie -tying die-dying注意：see-seeingdraw-drawinglisten-lis
3、tening现在分词构成口诀现在分词很好记，动词后缀-ing。直接加、去e加、双写加。还有一点要注意ie要用y来替。现在进行时用法口诀主语在前be在后，现在分词跟着走，其他成分不可丢。变一般很简单，把be提到句子前，否定句也不难，be后要把not添。还有一点要注意，动作提问doing替。现在进行时态练习题一、 将下列动词变成ing形式help_come_swim_eat_give_find_sit_write_tie_make_play_clean_catch_walk_ride_run_draw_listen_begin_dance_watch_sleep_see_have_二用所给词的适当
