语法考点一
一般现在时
【定义】一般现在时用于描述经常发生的动作、习惯、事实或普遍真理。它是最基本的时态之一,常用于日常对话和书面表达中。
1.实义动词的一般现在时(本册涉及知识点)
①肯定句:主语+动词原形(第三人称单数加 -s/-es)+其他。
例句:
I play football every weekend.(我每周末踢足球。)
She reads books every day.(她每天读书。)
②否定句:主语 + do/does + not + 动词原形 + 其他。
例句:
I do not (don’t) like coffee.(我不喜欢咖啡。)
He does not (doesn’t) play video games.(他不玩电子游戏。)
③一般疑问句:Do/Does + 主语 + 动词原形 + 其他?
例句:
Do you like pizza?(你喜欢披萨吗?)
Does she go to school by bus?(她坐公交车上学吗?)
动词第三人称单数变化规则
①一般情况: 动词后直接加 -s。
例: work → works play → plays
②以 -s, -sh, -ch, -x, -o 结尾: 动词后加 -es。
例: pass → passes wash → washes teach → teaches fix → fixes go → goes
③以辅音字母 + y 结尾: 变 y 为 i,再加 -es。
例: study → studies try → tries
④不规则变化: 有些动词的第三人称单数形式不规则。
例: have → has be → is
2.be动词的一般现在时
①肯定句:主语 + be动词 (am/is/are) + 其他。
例句:
I am a student.(我是一名学生。)
She is happy.(她很开心。)
They are teachers.(他们是老师。)
②否定句:主语 + be动词 (am/is/are) + not + 其他。
例句:
I am not tired.(我不累。)
He is not (isn’t) at home.(他不在家。)
We are not (aren’t) ready.(我们还没准备好。)
③一般疑问句:Be动词 (Am/Is/Are) + 主语 + 其他?
例句:
Are you okay?(你还好吗?)
Is she your sister?(她是你的妹妹吗?)
Am I late?(我迟到了吗?)
【经典例题】
用所给单词的适当形式填空。
She (have) breakfast at 7:15 every day.
点拨
答案:has
【详解】句意:她每天七点十五分吃早餐。本题考查动词的形式。根据every day可知句子是一般现在时,主语是第三人称单数She,谓语动词要用动词的第三人称单数形式,have breakfast吃早餐,have的第三人称单数形式为has,故答案为has。
