浙江省衢州市开化县池淮镇初级中学七年级英语语法复习 现在进行时的用法及练习（无答案） （新版）外研版.doc

现在进行时的用法及练习一、现在进行时的构成 现在进行时由be+v-ing构成。be应为助动词，初学者最容易漏掉，它应与主语的人称和数保持一致。 二、现在进行时的应用 在实际运用时，现在进行时常用以下几种情况：(1)当句子中有now时，常表示动作正在进行，这时要用现在进行时。如：they are playing basketball now.现在他们正在打篮球。(2)以look, listen开头的句子，提示我们动作正进行，这时要用现在进行时。如：listen！she is singing an english song.听，她正在唱英语歌。(3)表示当前一段时间或现阶段正在进行的动作，且此时有this week, these days等时间状语，这时常用现在进行时。如： we are making model planes these days.这些天我们在做飞机模型。 (4)描述图片中的人物的动作，也为了表达更生动。此时也常用现在进行时。如：look at the picture. the children are flying kites in the park.看这幅图，那些孩子正在公园放风筝。 三注意动词的现在分词的变化。 动词现在分词构成: 1正常变化是在动词原型后加ing 如:read-reading ; drink-drinking ; eat-eating ; listen- listening jump-jumping ; wear-wearing ; grow-growing ;collect-collecting2特殊变化:1) 以e结尾的动词，去掉e再加ing 如:write -writing ; make- making ; ride-riding ; take-taking2).以重读闭音节结尾的动词，如果末尾只有一个辅音字母，（ 只有一个元音字母，而其后跟有一个辅音字母时）要双写结尾的辅音字母再加ing例如sit-sitting ; swim-swimming ; put- putting ; run- running get-getting 四、现在进行时的变化 肯定句式：主语+be( am, is, are)+现在分词+其它.否定句式：主语+be(am, is, are) +not +现在分词+其它. 一般疑问句：be(am, is, are) +主语+现在分词+其它？ 特殊疑问句：疑问词+be(am, is, are)+主语+现在分词+其它？对现在进行时的特殊疑问句的回答，它不可以用yes或no直接作答，要根据实际情况回答。现在进行时专项练习一.按要求改写句子1. the boy is playing basketball.否定句：_一般疑问句：_肯定回答：_否定回答：_对“is playing basketball”提问：_对“ the boy”提问：_2.she,the window,open,now.(用现在进行时连词成句.)_3.the birds are singing in the tree.(就划线部分提问)_4.is,who,the window,cleaning?(连词成句)_ii.单项选择（ ）1.我在照看孩子.
