不用被動語態的情況
1) 不及物動詞或動詞短語無被動語態：
appear, die disappear, end , fail, happen, last, lie, remain, sit, spread, stand
break out, come true, fall asleep, keep silence, lose heart, take place.
After the fire, very little remained of my house.
比較： rise, fall, happen是不及物動詞;raise, seat是及物動詞。
The price has been risen.
The price has risen.
The accident was happened last week.
The accident happened last week.
The price has raised.
The price has been raised.
Please seat.
Please be seated.
要想正確地使用被動語態，就須注意哪些動詞是及物的，哪些是不及物的。特別是一詞多義的動詞往往有兩種用法。解決這一問題唯有在學習過程中多留意積累。
2) 不能用于被動語態的及物動詞或動詞短語：
fit, have, hold, marry, own, wish, cost, notice, watch agree with, arrive at / in, shake hands with, succeed in, suffer from, happen to, take part in, walk into, belong to
This key just fits the lock.
Your story agrees with what had already been heard.
3) 系動詞無被動語態：
appear, be become, fall, feel, get, grow, keep, look, remain, seem, smell, sound, stay, taste, turn
It sounds good.
4) 帶同源賓語的及物動詞，反身代詞，相互代詞，不能用于被動語態：
die, death, dream, live, life
She dreamed a bad dream last night.
5) 當賓語是不定式時，很少用于被動語態。
She likes to swim.
