【文章內(nèi)容簡(jiǎn)介】 e any water in the glass?There isn39。t any water in the glass.(2)在說(shuō)話者希望得到肯定答復(fù)的一般疑問(wèn)句中，或在表示請(qǐng)求，邀請(qǐng)的疑問(wèn)句中，我們依然用some。如：Would you like some tea?9. tall/ high (1)說(shuō)人，動(dòng)物，樹(shù)木等有生命的東西，主要用tall，不用high，例如 a tall woman 一個(gè)高個(gè)子?jì)D女 a tall horse 一個(gè)高大的馬 (2)說(shuō)一個(gè)不與地面接觸的人和物的高時(shí)，要用high，而不用tall，比如人站在桌子上時(shí)，飛機(jī)飛上天時(shí)，例如： He is high up in the tree. 他高高地爬在樹(shù)上。 The plane is so high in the sky. 飛機(jī)在空中這么高。 (3)指建筑物、山時(shí)要tall或high都可以，不過(guò)high的程度比tall高。 (4)high可作副詞，tall不能。 (5)tall的反義詞為short, high的反義詞為low.10. can/ could(1) can表示體力和腦力方面的能力，或根據(jù)客觀條件能做某種動(dòng)作的能力。例如： Can you ride a bike？ 你會(huì)騎自行車嗎？ What can I do for you？ 要幫忙嗎？ Can you make a cake？你會(huì)做蛋糕嗎？(2) can用在否定句和疑問(wèn)句中時(shí)有時(shí)表示說(shuō)話人的懷疑猜測(cè)或不肯定。例如：Where can he be？他會(huì)在什么地方呢？Can the news be true？這個(gè)消息會(huì)是真的嗎？It surely can39。t be six o39。clock already？不可能已經(jīng)六點(diǎn)鐘了吧？You can39。t be hungry so soon，Tom，you39。ve just had ，你不可能餓得這么快，你剛吃過(guò)午飯。What can he mean？他會(huì)是什么意思？在日常會(huì)話中，can可代替may表示允許，may比較正式。例如：You can e in any 。 Can I use your pen？我能用你的鋼筆嗎？ Of course，you 。You can have my seat，I39。m going ，你坐我的座位吧。(3) couldcould 是 can的過(guò)去式，表示過(guò)去有過(guò)的能力和可能性（在否定和疑問(wèn)句中）。例如： The doctor said he could help him.（能力）醫(yī)生說(shuō)他能幫助他。 Lily could swim when she was four years old.（能力） 當(dāng)麗麗四歲的時(shí)候她就會(huì)游泳。At that time we thought the story could be true.（可能性）那時(shí)我們以為所說(shuō)的可能是真的。 could可代替can表示現(xiàn)在時(shí)間的動(dòng)作，但語(yǔ)氣較為婉轉(zhuǎn)。例如：Could I speak to John，please？我能和約翰說(shuō)話嗎？ Could you？在口語(yǔ)中表示請(qǐng)求對(duì)方做事。例如：Could you wait half an hour？請(qǐng)你等半個(gè)小時(shí)好嗎？Could you please ring again at six？六點(diǎn)鐘請(qǐng)你再打電話好嗎？(4) can的形式只有現(xiàn)在式can和過(guò)去式could兩種形式。能表示一般現(xiàn)在和一般過(guò)去兩種時(shí)態(tài)，有時(shí)也能表示將來(lái)。所有其他時(shí)態(tài)（包括將來(lái)時(shí)）須用be able to加動(dòng)詞不定式來(lái)表示。例如： They have not been able to e to Beijing. 他們沒(méi)有能到北京來(lái)。11. look for/ findlook for 意為“尋找”，而find意為“找到，發(fā)現(xiàn)”，前者強(qiáng)調(diào)“找”這一動(dòng)作，并不注重“找”的結(jié)果，而后者則強(qiáng)調(diào)“找”的結(jié)果。例如：She can’t find her ruler. 她找不到她的尺子啦。Tom is looking for his watch，but he can’t find ，但沒(méi)能找到。12. be sleeping/ be asleepbe sleeping 表示動(dòng)作，意思是“正在睡覺(jué)”；be asleep 表示狀態(tài)，意思是“睡著了”。如：What are the children doing in the room? 孩子們?cè)诜块g里做什么？They are 。The children are asleep 。13. often/ usually/sometimesoften表示經(jīng)常，sometimes表示有時(shí)候，在表示發(fā)生頻率上often要高于usually，usually要高于sometimes。這三個(gè)詞表示的是經(jīng)常性，一般性的動(dòng)作或情況，常與一般現(xiàn)在時(shí)連用，常位于主要謂語(yǔ)動(dòng)詞的前面，其他謂語(yǔ)動(dòng)詞（be動(dòng)詞，情態(tài)動(dòng)詞和助動(dòng)詞）的后面，有時(shí)也可位于句尾。如果要加強(qiáng)語(yǔ)氣，則放在句首。 We usually play basketball after 。Sometimes I go to bed ，我睡覺(jué)很早。He often reads English in the 。14.
