1. be动词easy
2. 否定后加not，疑问就移be
3. 移到主语前，形成疑问句
1. be动词 easy
be动词的否定／疑问句很简单，不像实义动词需用助动词do / does。
2. 否定后加not，疑问就移be
否定句只要在be动词后面加上not；而疑问句则需移动be动词。
3. 移到主语前，形成疑问句
将be动词移到主语前即可改成疑问句。
语法概念说给你听
（一）be动词的否定句
中文的“不是”，其否定词“不”是加在动词前；而英文是在be动词之后加 not。例：am not → 通常不缩写
are not → 缩写成aren't
is not → 缩写成isn't
（二）be动词的疑问句
中文是在句尾加上“吗？”，而英文是将 be动词移到句首并大写，句尾加“？”。例：Am I... ? / Are you... ? / Is he... ?
（三）be动词的否定疑问句
将be动词移至主语前，主语后加not。
例：Am I not... ? / Are you not... ? = Aren't you... ?
Is he not... ? = Isn't he... ?

1. 实义动词现在式，何时加-s
2. I，you和复数用原形，其余单数加-s
1. 实义动词现在式，何时加-s
实义动词的现在式，什么时候加-s？在第三人称单数（比如he, she,Mary, your friend...）这些主语的动词后面加-s。
2. I，you，复数用原形，其余单数加-s
主语是 I，you和复数时，如：we（我们）/ they（他们）/ the boys（男孩们）就用动词原形。
语法概念说给你听
英语中的动词现在式分成动词原形及动词的第三人称单数形式，到底怎么使用？
注意！除了 I / you 一定接动词原形，如 I eat / you eat，其他则分为两大类：
（一） 主语是单数：如 he / she（他／她）/ your sister（你妹妹），就搭配使用动词原形加 -s → he eats / she eats / your sister eats...
（二） 主语是复数：如 we（我们）/ they（他们）/ the boys（男孩们），就搭配使用动词原形 → we eat / they eat / the boys eat...
总结：主语如果不是 I，you 或复数，就需使用动词原形加 -s
动词的现在式加-s的用法：
1. 动词原形 →加 -s（如：cooks / likes / eats...）
2. 词尾以字母 x / o / s / z / sh / ch 结尾的 →加 -es（如：do → does / watch →watches）
3. 动词以“辅音加字母 y”结尾的 →去 -y 加-ies（如：study → studies / hurry→ hurries）

study是以-y结尾的，所以动词的第三人称单数形式要去-y加上-ies才正确。

The students是复数，go的后面不需加上-es。
语法口诀轻松记
1. 实义动词否定、疑问要人帮，助动词来帮忙
2. 否定 don't / doesn't 挡在动词前
3. 疑问要由 Do / Does 来引导
1. 实义动词否定、疑问要人帮，助动词来帮忙
实义动词和 be 动词不一样，需要助动词 do / does 来帮忙形成否定和疑问句。
2. 否定 don't / doesn't 挡在动词前
否定句在动词之前加上助动词，变成“don't / doesn't＋动词原形”。
3. 疑问要由 Do / Does 来引导
疑问句在句首加上助动词，变成“Do / Does...＋动词原形”。
语法概念说给你听
（一）实义动词的否定句
在动词前加上助动词，变成don't / doesn't ＋动词原形。
do not → 缩写成 don't，例如：I don't know.
does not → 缩写成 doesn't，例如：He doesn't know.
（二）实义动词的疑问句
在句首加上助动词，变成Do / Does...＋动词原形。
例如：Do you know her? / Does he know her?
补充：否定疑问句这样写，例如：
Do you not... ? ＝ Don't you... ?
Does he not... ? ＝ Doesn't he... ?
高分小秘诀
主语为第三人称单数时，加上助动词 does / doesn't后，注意实义动词要变回动词原形！
