人教版英语七年级下册关于一般现在时知识突破
英语时态是英语知识的一个重点,也是一个难点。接下来,我们就来给大家总结一下一般现在时的相关知识。
基本用法。

例如:When do you get up every morning? 你每天早上几点起床?
例如:What do you have for breakfast every morning 你每天早上的早餐吃什么?
表示现在的状态、喜好等。
例如:Are you new in our school 你是新来我们学校的(新同学)吗?
又如: I like playing soccer very much. 我非常喜欢踢足球。
客观事实、普遍真理。
例如:Do you come from Canada 你来自加拿大吗?
又如:The sun rises in the east. 太阳从东边升起来。
基本结构。
含有be动词型。
例如:She is twelve years old. 她十二岁。
又如:They are from China. 他们来自中国。
实意动词原形。
例如:They like bananas very much . 他们非常喜欢香蕉。
又如:We don't have time today. 我们今天没有时间。
实义动词第三人称单数形式。

又如:Jim does his homework in the evening. 吉姆晚上做他的家庭作业。
又如:My mother doesn't work in a hospital. 我的妈妈没在医院工作。
小结:时态问题归根到底就是动词形式问题。

什么是第三人称单数?
非你、非我、非复数,当主语是第三人称单数时,谓语动词用相应的第三人称单数。
动词第三人称单数变化规则如下:
一般情况下直接在词尾加-s,like-likes ;live-lives ; speak-speaks
以-s, -x, -ch, -sh 结尾的单词在词尾加-es , teach-teaches ; watch-watches
以辅音字母+y结尾变y为i再加es ; study-studies
以元音字母+y结尾在词尾加-s ; play-plays ; stay-stays ; say-says
以o结尾在词尾加-es
部分不规则变化 ; have-has 。
