這個句子對嗎

一樓正確 是賓語補足語
ps.
加her表明going這一動作的執(zhí)行者是她，不是我。
我只是認(rèn)為她去那里很危險
is不是省略，
是用賓語補足語，還是用賓語從句的選擇

her going there alone at night是it的同位語從句。完全同意樓上所說。

成立。dangerous在這作it的賓補，可以改成主從復(fù)合句
think it is dangerous her going there alone at night

正確的
dangerous是it的賓語補足語這是it的常用語式
her going there alone at night 是it（形式賓語）的同謂語
轉(zhuǎn)變一下就是I think her going there alone at night is dangerous.

這句話不對
I think it is dangerous (for) her to go there alone at night.
不過dangerous在it后面，其實就是省略了is ，這樣的用法是對的，只是漏了for

同謂語的話要加逗號,is 可以隨便省略

i think it dangerous， her going there alone at night.
