例：①陈述句：She is a student.
疑问句→ Is she a student?
否定句→ She is not a student.
②陈述句：I can swim.
疑问句→ Can you swim
否定句→ I can not swim.
（2）当句子中即没有be动词，也没有情态动词时，则在主语前加助动词do (you,以及复数), do es（单数she,he,it）变成问句；在主语后谓语动词前加助动词don’t（I,you,以及复数), doesn’t（单数s he,he,it）变成否定句，助动词后的动词要变成动词原形。
例：①陈述句：We get up at 7:00 every morning.
疑问句→Do you get up at 7:00 every mor ning?
否定句→We don’t get up at 7:00 every morning.

一般现在时的用法
同学们，大家学习了一般现在时的用法，下面咱们来归纳一下：
1．概念：一般现在时表示经常的、习惯性的动作或存在的状态。
2．构成：一般现在时的构成主要有两种形式：
（1）be型：句子的谓语动词只有be（am，is
或are）：
a．肯定句中，只出现be，如：
I am a student．我是一名学生。
b．否定句中，要在be后面加not，如：
She isn't a teacher．她不是教师。
c．一般疑问句，要将be放在句子开头（注意句首字母大写），句尾用问号，答语用Yes，主语+be．或No，主语+be+not．如：
—Are you ready？—你准备好了吗？
—Yes，I am．—是的，我准备好了。
（—No，I'm not．—不，我没准备好。）
（2）实义动词型：句中的谓语动词为实义动词（也叫行为动词）：
a．肯定句中，只出现实义动词，如：
I get up in the morning．我早晨起床。
b．否定句中，要在实义动词前面加do（does）＋not，do（does）作助动词，本身无意义，常与not缩写成don't（doesn't），如：
I don't like vegetables．我不喜欢蔬菜。
c．一般疑问句，要在句子开头加助动词Do （does），句尾用问号，简略答语用Yes，主语+do（does）．或No，主语+do（does）＋not．如：
—Do you like oranges？—你喜欢桔子吗？
—Yes，I do．—是的，我喜欢。
（—No，I don't．—不，我不喜欢。）
Ann Wang writes good English but does not speak well.
比较：Now I put the sugar in the cup.
I am doing my homework now.
第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。再如：Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。
