修改如下：
I don't know how big Beijing is.
Beijing has got lots of animals.
My hometown is Beijing.


保證準(zhǔn)確率~



為什么，請(qǐng)講講知識(shí)！

好的

1. I don't know 是主句，后面從句為陳述語(yǔ)序，即 連接詞how+主語(yǔ)Beijing+謂語(yǔ)is

2. is, got 同為動(dòng)詞，一個(gè)句子一般不出現(xiàn)兩動(dòng)詞，所以把is換成has, has got = has

3. 我的家鄉(xiāng)是北京My hometown is Beijing.   Beijing做表語(yǔ)，不用加in the

那如果是My hometown in Beijing呢，有沒(méi)有錯(cuò)？有錯(cuò)噢少謂語(yǔ)，不用in應(yīng)該是 My hometown is Beijing.
