3. 被動語態中值得註意的問題：
○1 帶有雙賓語的動詞，可以把任何壹個賓語變被動，壹般在間接賓語前加適當的介詞。My father gave me a book ./ I was given a book by my father ./ A book was given to me by my father .
○2 英語中有些動詞用主動語態表示被動語態。The cloth washes well ./ This kind of bags sells well. / The shoes wear long. / The knife cuts well . / The pen writes smoothly . / This coat lasts long .
○3 在英語中有時"be + V-ed"結構並不是被動語態，而是系表結構。The mountains were covered with snow .
○4 在"主語+謂語+賓語+賓語補足語"的結構中，要補留賓語補足語。We found the door broken. / The door was found broken.
○5 賓語補足語為省to的不定式，變為被動語態後，要還原to。He made me laugh. / I was made to laugh .
○6 如果短語動詞是及物動詞時，可以用被動語態，但不能遺漏所含的介詞或副詞。The nurse looked after the baby ./ The baby was looked after by the nurse . / We must make up for the lessons we missed. / The lessons we missed must be made up for .
○7 下列情況不能用被動語態：
A. 不及物動詞： The accident happened on a busy road yesterday .
B. 連系動詞： The girl looks like her sister .
C. 賓語為反身代詞：He always dresses himself neatly .
D. 賓語為相互代詞：The students often help each other .
E. 同源賓語：At that time, they lived a happy life .
F. 表示狀態的及物動詞：I have a new car. / The book cost me 30 yuan .
