iv. 重要語法
1. 賓語從句
2. 現在完成時
3. 一般過去時與現在完成時的用法比較：
【名師講解】
1. 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 come tomorrow?”“maybe not.” “他明天來嗎？”“也許不”。
(2) may be相當于是情態動詞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 arrive.他們可能于九點到達。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 library.我們經常從學校圖書館借書。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 bike.謝謝你把自行車借給我。he often lends money to his brother.他經常借錢給他弟弟。
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，是一段持續的時間，因此可以與時間段連用。例如：you can keep my recorder for three days.我的錄音機你可以借用三天。
i have kept this book for only one week.這本書我才剛借了一星期。
(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 telephone.他不得不使用這部公用電話。
3. leave/ leave for
(1) leave意思是“離開，留下”。 例如：we left shanghai two years ago.我們兩年前離開了上海。
he left his cell phone in the taxi last week.他上周把手機落在出租車里了。
(2) leave for意思是“前往”，表示要去的目的地。例如：we will leave for tibet next month.我們將于下月去西藏。the train is leaving for moscow.這趟火車即將開往莫斯科。
