1、不可遺漏being。現在進行時的被動語態表示說話時正在進行的一個被動的動作，如果我們把being漏掉，即成為一般現在時的被動語態或系表結構。注意事項(一般現在時的被動語態)注意事項2、許多

“不及物動詞+副詞或介詞”

或“及物動詞+賓語+介詞”構成的短語動詞，相當于及物動詞，可以有被動語態。變被動語態時不可漏掉介詞或副詞:laughat,

operateon,lookafter,takecareof,thinkof,talkabout,handin,catchsightof,makeuseof,payattentionto...e.g.

Mysisterisbeingtakencarebygrandma.

e.g.

Thepatientisbeingoperatednow.ofon瑪麗,過來,有你的電話。Mary,comehere.

You

arebeingwanted

onthephone.Mary,comehere.

You

arewanted

onthephone.3、沒有進行時的被動語態：一些表示狀態、心理活動、擁有、存在等的動詞，如have,want,need,like,realize等，一般不用于進行時的被動語態，而常用一般現在時的被動語態表示此時此刻或目前主語正在承受謂語動詞表示的動作。注意事項4、“be+under/in+名詞”結構有時可相當于現在進行時的被動語態。
