最新人教版英语七年级下册第五单元语法知识突破
Unit 5 Unit 5 Here and now
2024版人教版英语七年级下册第五单元的语法是现在进行时。接下来,我们就从这个语法(时态)的用法和结构等方面给大家一一展开。另外,配有少量练习,帮助大家检测对这个时态的掌握情况。
关于现在进行时
1.、意义:表示现在(说话时)正在进行的动作或存在的状态,也可表示当前一段时间或现阶段正在进行的动作或存在的状态。
2、结构:由“be(am/is/are)+动词 -ing形式”构成。be动词必须与主语在人称和数上保持一致,即“I后用am,you后用are,he/she/it后用is。主语是单数用is,主语是复数用are”。
3、动词 -ing形式的构成:一般动词在词尾加 -ing;以不发音的字母e结尾的动词,先去掉字母e,再加 -ing;以重读闭音节结尾且末尾只有一个辅音字母的动词,双写该辅音字母,再加 -ing;少数以ie结尾的动词,变ie为y,再加 -ing。
4、关于现在进行时的时间状语或标志词有:look,listen,(right)now,at the moment,at present等。
5、具体运用:
(1) 、肯定句:主语 + be(am/is/are ) + 动词 -ing形式 + 其它。 例如:Sam is having dinner at home with his parents now. 山姆现在正在家和父母一起吃晚饭。
(2) 否定句:主语 + be(am/is/are) + not + 动词 -ing形式 + 其它。 例如:Sam is not (isn’t) having dinner at home with his parents now. 山姆现在不是在家里和父母一起吃晚饭。
(3) 、一般疑问句:Be ( Is \ Am \ Are ) + 主语 + 动词 -ing形式 + 其它?例如:Is Sam having dinner at home with his parents now? 山姆现在正在家里和父母一起吃晚饭吗?
(4) 、特殊疑问句:
What are you doing at the beach? 你正在沙滩上做什么?
What’s your brother doing? 你的兄弟正在做什么?
What are they doing? 他们正在做什么?
6、 现在进行时需要注意的地方:be动词和动词的ing形式缺一不可!
