Maybe/ may be (1) maybe 是副詞,意思是 “大概,也許 ”,常用作狀語。例如: Maybe you put it in your bag.也許你把它放在包里了。 “Will he e tomorrow?”“Maybe not.” “他明天來嗎? ”“也許不 ”。 (2) may be相當于是情態(tài)動詞 may 與 be動詞搭配一起作謂語,意思是 “也許是 … ,可能是 …” 。 例如: It may be 9:00 when they 。 The man may be a lawyer. 那人也許是律師。 2. borrow/ lend/ keep/ use (1) borrow 表示的是從別人那里借來東西,即我們通常所說的 “借進來 ”。例如: We often borrow books from our school 。 I borrowed this dictionary from my teacher. 我從老師那兒借來了這本字典。 borrow 是一個瞬間完成的動作,因此不能與時間段連用。 例如: You can borrow my recorder for three days. ( 錯誤 )I have borrowed this book for only one week. ( 錯誤 ) (2) lend 表示的是把自己 的東西借給別人,即我們通常所說的 “借出去 ”。 例如: Thank you for lending me your 。 He often lends money to his 給他弟弟。 lend 與 borrow 一樣,也是一個瞬間完成的 動作,不能與一段時間連用。 (3) keep 的意思也是 “借 ”,但一般是指借來后的保存或使用階段,是一段持續(xù)的時間,因此可以與時間段連用。例如: You can keep my recorder for three 天。 I have kept this book for only one 。 (4) use 也可以當 “借用 ”講,但它的本意是 “用,使用 ”。例如: May I use your ruler? 我能借你的尺子用一下嗎? He had to use this public 。 3. leave/ leave for (1) leave 意思是 “離開,留下 ”。 例如: We left Shanghai two years 海。 He left his cell phone in the taxi last 。 (2) leave for 意思是 “前往 ”,表示要去的目的地。例如: We will leave for Tibet next 們將于下月去西藏。 The train is leaving for 。 4. since/ for (1) since 用于完成時態(tài),既能用作介詞,也能用作連詞,后常接時間點,意思是 “自從 ”。 例如: He has been a worker since he came into this ,他就是工人了。 I have never seen him since we last met in Shanghai .自從我們上次在上海見過之后我再也沒見過他。 since 作連詞,還有 “既然 ”的意思。例如: Since you are interested in it, just do it. 既然你對它感興趣,那就做吧。 You can have fun now since you’ve finished your 了功課,就開心玩會兒吧。 (2) for 用于完成時,用作介詞,后常接一段時間,意思是 “經(jīng)過 …” 。例如: I have learned English for five 。 They have waited for you for 30 經(jīng)等了你三十分鐘了。 for 也可以用作連詞,但意思是 “因為 ”。 例如: They missed the flight for they were 由于完到了而誤了航班。 He fell ill for many 。 5. neither/ either/ both (1) neither 作代詞是對兩者都進行否定,意思為 “兩者都不 ”,作主語時謂語動詞用單數(shù) .例如:Neither of the boys is from 。 I know neither of them. 他們兩個我都不認識。 neither 用作形容詞,也修飾單數(shù)名詞,意思與作代詞時相同;用 作連詞時,一般與 nor 搭配,表示 “既不 … 也不 ”。作主語時,謂語動詞也遵循就近原則。 例如: She neither ate nor drank yesterday.
