一般现在时的两种构成形式
记住:doesn't或don't后一定跟动词原形
isn't/aren't/am
not
可以跟名词，介词（比如in)，形容词等，如果跟动词．后跟的动词要么是ing形式表示进行,动词不定式 to
do表示将来，要么是done表示被动．
而且你的第一个句子应该是：
Her
Father
isn't
in
Beijing.
不是＂she's
father"

英语一般现在时基本结构造句
一般现在时的基本结构主要有两种形式：
（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.）

（2）一般过去时
