U please help me?Unit 12 You’ re supposed to shake hands 重難點(diǎn)解析（2）1. be supposed to do sth.被期望做某事，應(yīng)該做某事肯定句/否定句/疑問句，一般現(xiàn)在時(shí)/一般過去時(shí)，這樣的變化都體現(xiàn)在be動詞上。請看例句：Japanese are supposed to bow when they meet people for the first time.I am not supposed to bow, I am supposed to shake hands when I meet people for the first time.I was supposed to e at 7:00, but I came at 8:00.2 point 的用法point at sb. 指著某人It’s not polite to point at others. 用手指著別人是不禮貌的。point + 名詞/代詞 削尖(鉛筆)，增加……的力量He told a story to point his advice. 他將了個(gè)故事以增強(qiáng)他的說服力。e to the point 到緊要關(guān)頭，到達(dá)要點(diǎn)When it came to the point, he refused his help. 到緊要關(guān)頭時(shí)，他拒絕援助。point out 指出，使注意We’ll correct our mistakes whoever points them out.無論誰指出我們的錯(cuò)誤，我們都會改正。to the point 中肯The reply was short and to the point.回答得簡明扼要。3…should have arrived…這是should have + 過去分詞的用法，表示過去本該做某事，但實(shí)際上卻沒做。如果是shouldn’t have + 過去分詞，表示過去本不該做某事，那么意味著已經(jīng)做了。You are right. I should have thought of that.你說得對，我本應(yīng)該想到這一點(diǎn)。It’s sunny all year round here. I shouldn’t have taken an umbrella with me. 這里一年四季天晴。我本不該帶傘的。4 幾個(gè)used的用法在本單元、第2單元和10單元中，都出現(xiàn)了used，用法還不一樣，我們集中一起來學(xué)習(xí)一下。請先看例句。1. I used to be afraid of the dark.我過去常常怕黑。2. Light bulbs are used for seeing at night.電燈是被用來晚上照明的。3. I’m gradually getting used to things.我漸漸習(xí)慣了這些事情。句1是used to do sth. 是“過去常常怎么樣/做什么”的意思。其中used可以把它看作是個(gè)過去式，那么在變成否定句和疑問句時(shí)，我們要借did幫忙，而且注意did后要放原形。所以這句話我們可以變成: I didn’t use to be afraid of the dark. 我過去不常常怕黑。Did you use to be afraid of the dark? 你過去常常怕黑嗎？句2：be used to do sth. be used for doing sth. 這兩個(gè)用法都表示某物被用來干什么。注意前者to后要放動詞原形。后者介詞for 后要用動詞的ing形式。比如例句也可以改成：Light bulbs are used to see in the dark. 否定句和疑問句就是在be動詞上動腦筋，used不變。我們把句2變成否定句，就是： Light bulbs are not used for seeing at night. 變成一般疑問句即是： Are light bulbs used for seeing at night?句3：be/get used to doing sth. 習(xí)慣于做某事。注意這里的to是個(gè)介詞，所以后面的動詞一定要加ing。be used to doing sth. 在句中做謂語時(shí)，變否定句和疑問句都是在be動詞上動腦筋，used不變。get used to doing sth. 在句中做謂語時(shí)，變否定句和疑問句要借do/does幫忙。5 it is + adj.（形容詞）+ for sb.+ to do sth. 對某人來說做某事怎么樣It is difficult for me to practice the violin every day.對我來說，每天練習(xí)彈小提琴很困難。在這里，to do sth. 是真實(shí)的主語，it是個(gè)形式主語，所以在翻譯時(shí)要把真實(shí)的主語放前面來，it不要翻譯9
