如：look 看 (vi.) x賓語(即不能直接加賓語).Look!She is singing.
Look carefully!(註意：carefully 是副詞,不是名詞,故不作賓語)
look at 看…….+賓語 Look at me carefully!(me是代詞,作賓語)
at是小範圍 in是大範圍
如：
The students work very hard.學生們學習很努力.
She apologized to me again.她再次向我道歉.
The accident happened yesterday evening.事故是昨天晚上發生的.
分清及物不及物動詞:
分清動詞的及物不及物是在英語學習中必須解決的首要問題.動詞及物與不及物通常有以下幾種情況：
a．主要用作及物動詞.及物動詞後面必須跟賓語.可以用於："主＋謂＋賓"；"主＋謂＋雙賓"；"主＋謂＋賓＋賓補"結構.如：
He reached Paris the day before yesterday.
Please hand me the book over there.
They asked me to go fishing with them.
類似的還有：buy,catch,invent,found,like,observe,offer,prevent,promise,raise,find,forget,receive,regard,see,say,seat,supply,select,suppose,show,make,take,tell.
b．主要用作不及物的動詞.不及物動詞後面不跟賓語.只能用與："主＋謂"結構.
This is the room where I once lived.
類似的還有：agree,go,work,listen,look,come,die,belong,fall,exist,rise,arrive,sit,sail,hurry,fail,succeed.
c．既可以用作及物又可以用作不及物的動詞,其意義不變.如begin 都是作"開始"講.everybody ,our game begins.let us begin our game.類似的還有：start,answer,sing,close,consider,insist,read,learn,prepare,pay,hurt,improve.
d．既可以用作及物又可以用作不及物的動詞,其意義完全不同.
這類動詞作不及物動詞是壹個意義；而作及物動詞時卻是另壹個意義.如lift作不及物動詞時是指煙霧的"消散".we saw the mountain when the clouds lifted.作及物動詞時是"升高；舉起".
He lifted his glass and drank.
類似的還有：beat vi.跳動 vt.敲、打; grow vi.生長 vt. 種植
play vi.玩耍 vt.打（牌、球）,演奏 smell vi.發出（氣味） vt.嗅
ring vi.（電話、鈴）響vt.打電話 speak vi.講話 vt.說（語言）
hang vi.懸掛 vt. 絞死 operate vi.動手術 vt.操作
