備戰(zhàn)2020中考英語(yǔ)總復(fù)習(xí)資料
［析］ 作"拜訪"講時(shí)，at后面接訪問(wèn)地點(diǎn)，而on后面接訪問(wèn)的人。
call on drop in visit
call on比較正式的為公務(wù)的訪問(wèn)，如：we were called on by the old students. 而drop in則是比較隨便的走走，順便拜訪，如：if you're free, drop in. 而visit則是更正式的外交訪問(wèn)或友好往來(lái)，如：my school's headmaster will visit america next week.
can
［誤］ a blind man can not judge colours.
［正］ a blind man cannot judge colours.
［誤］ i cann't call for you at ten.
［正］ i can't call for you at ten.
［析］ can的否定形式應(yīng)為cannot或can't.
［誤］ it's only six o'clock. that mustn't be the postman.
［正］ it's only six o'clock. that can't be the postman.
［析］ must用來(lái)表示一種肯定的推斷，如：she must have some problems. she keeps crying. 但在否定句中則要用can't， 要表示對(duì)過(guò)去的推測(cè)則要用"must+have+過(guò)去分詞"的表達(dá)法，如：the lights have gone out.a fuse must have blown.而對(duì)過(guò)去的否定推測(cè)則多用"can't+have+過(guò)去分詞"，如：i don't think he can have heard you. call again.
［誤］ we could not help to laugh at once.
［正］ we could not help laughing at once.
［正］ we could not help but laugh at once.
［析］ "couldn't help+動(dòng)名詞"表示禁不住做了某事。但could not help but與could not but后面要加不帶to的不定式，意思都是不得不去做某事.如：you could not (help) but respect him.
can be able to
can與be able to都可以用來(lái)表示能力，但can只有現(xiàn)在時(shí)與過(guò)去時(shí)，be able to則可用任何時(shí)態(tài)，如：he will be able to teach the child. 但要表示經(jīng)過(guò)努力而達(dá)到的一次性動(dòng)作則只能用be able to，如：he finally was able to jump over 210 meters. 或：the plane was able to fly over the mountain. 但要注意的是這兩個(gè)詞都沒(méi)有進(jìn)行時(shí)態(tài)，而be able to后面不接不定式的被動(dòng)態(tài)。
can could
can與could都可以用在現(xiàn)在時(shí)的口語(yǔ)中，只是用could更為禮貌，語(yǔ)氣更委婉。如：could you tell us a story?
care
［誤］ i don't care coffee.
［正］ i don't care for coffee.
［誤］ take care for your steps.
［正］ take care of your steps.
［析］ care for是"對(duì)某物感興趣"，而care of是"關(guān)心，要當(dāng)心某事"，如：she didn't care for him. take care of what you are doing.
［誤］ i don't care where we will go if it doesn't rain.
［正］ i don't care where we go if it doesn't rain.
［析］ 在it doesn't matter, i don't care, i don't mind, 及in case引出的狀語(yǔ)從句后面要用現(xiàn)在時(shí)表示將來(lái)。如：i've got a football in case we have time for a game.
change
［誤］ i want to change my camera with that one.
［正］ i want to change my camera for that one.
［析］ change for為"以某物為交換物"。而change with則是"隨……而變"，如：the wood's colour changed with the season.
