初一英语现在进行时讲解及练习

现在进行时一、现在进行时的构成：现在进行时由be+现在分词（v-ing）构成。Be动词应与主语的人称和数保持一致，即：I am/he/she/it 包括单数名词和不可数名词用is, you/we/they 包括复数名词用are. The students are listening to the teacher.He is watching TV now.现在分词变化规则如下：1.动词后直接+ ing(例：sleep+ing sleeping) 2.去掉不发音的e+ing(例：bite-e+ing biting write-writing, make-making take-taking) 3.重读闭音节，且末尾只有1个辅音字母，双写辅音字母+ing(例:sitting, beginning,getting,putting，running，stopping，cutting ） 4.特殊变化：die-dying,lie-lying，tie-tying写出下例动词的现在分词形式1） give_ 2）use_ 3）move_ 4）skate_ 5）draw_ 6） tell_ 7）ring_ 8）wear_ 9）get_ 10）put_ 11） hit_ 12）stop_ 13）keep_ 14）hurt_ 15）know_ 16） lie_ 17）die_ 18）begin_ 19）forget_ 20）save_ 21）close_ 22）see_ 23）carry_基本结构：肯定式 I am working.You are working.He (she) is working.We (you,they) are working.否定式I am not working.You are not working.He (she) is not working.We (you,they) are not working.疑问式Are you working?Are you working?Is he (she) working?Are we (you,they) working?2、 现在进行时的应用A表示现在( 指说话人说话时) 正在发生的事情(now，at the moment ) What are you doing?I am watch TV now. B. 表示当前一段时间内的活动或者现阶段正在进行的动作(these days，this week，this month,this term)We are working on a farm these days.Im reading a history book this month.C.已经确定或安排好的将来活动。 Im leaving for a trek in Nepal（尼泊尔） next week.（已经安排了） were flying to Paris tomorrow.(票已经拿到了）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。We are having an English class at the moment.我们正在上英语课。(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。一、用现在进行时连写句子1）Li Ping;learn;to;speak;English;2）it;rain;now3）they;watch;a football match;on TV4）he;look;out of the window;5）look;the dog;sleep;6）listen;the baby;cry;7）they;have a meeting;at seven oclock8）the students;prepare for;an English test;now;二、用动词的正确时态填空1）I_(talk).You_(listen)tO me now.2）Look,the boy_(run)fast.3）-What are you doing? -I_(do) my homework.4）-_the students_(read) English?-Yes,they are.5）Tom_(not study)English.He is studying Chinese.6）-Who_(sing)a song? -Li Ying is.7） The girl_(not eat)bananas now.
