S:請學(xué)生回答；老師給出例子I spotted someone ing out of the buildingT:as the evidence began to accumulate, experts from the Zoo felt obliged to investigate……Accumulate means to gradually increase over a period of time 指的是逐漸增加或積累T:feel obliged to 這是一個(gè)固定詞組，經(jīng)常用來做書面語，同must，have to，have a duty to do 必須有義務(wù)、責(zé)任做……事 S:請學(xué)生回答并給出例子eg：I felt obliged to invite himT:The hunt for the puma began in a small village where a woman picking blackberries saw a large cat。Hunt 捕獵 搜尋T:請同學(xué)翻譯go on a deer /fox hunt 獵（鹿、狐）；The hunt for the remains of the titanic（搜尋TITANIC殘?。?；Hunt for secondhand book（搜尋二手書）；Jobhunting（找工作）T:Pick采摘；Pick cotton摘棉花；S:請學(xué)生翻譯We need to pick someone reliable 挑選我們要找一個(gè)可靠的人，Pick and choose 挑挑揀揀T:A puma will not attack a human being unless it is cornered。Cornered 陷入困境 被逼得走投無路T:The search proved difficult。Prove=turn out to be 證明是 原來是VI S:請學(xué)生翻譯They proved her innocence他們證實(shí)了她是無辜的（證實(shí)VT）；The rumor proved false 謠言證明是錯(cuò)誤的；T:Puma fur was found clinging to bushes ；Cling to 粘住 Clingclungclung 過去式過去分詞。S:學(xué)生翻譯His wet shirt clung to his body ；She clings to the belief that her Husband will e back 她固執(zhí)的相信她的丈夫會(huì)回來T:Some people plained of ‘cat like noises’ at night ……表示報(bào)告或者是述說,表示一種不滿的情緒T:plain跟的介詞不同意思也不同plain about the weather 抱怨天氣不好。plain of a headache 述說自己頭疼T:It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside，disturbing在這里等同worrying令人擔(dān)憂的不安的Disturb 打攪 Sorry to disturb you 對不起打擾你了。Do not disturb，請勿打擾！，His strange behavior disturbed me 他舉止反常讓我很擔(dān)心T:However, as the evidence began to accumulate, experts from the Zoo felt obliged to investigate, for the descriptions given by people who claimed to have seen the puma were extraordinarily :大家都知道 在英文中基本的句型就是簡單句 并列句以及復(fù)雜句，就是我們經(jīng)常聽到的simple sentences pound sentences plex sentences,這篇課文主要是由復(fù)雜句構(gòu)成的，now look at sentence please ,要理解一個(gè)復(fù)雜句，最重要的是要搞清句子的結(jié)構(gòu)，然后通過連接詞，分清主句和從句之間的關(guān)系，就是說要把握主句和從句的位置，而主句和從句的關(guān)系是由連接詞來判斷的，在這個(gè)句子當(dāng)中，主句就是experts from the Zoo felt obliged to investigate，主句前邊有一個(gè) as引導(dǎo)的從句，他表示的是一種伴隨主句同時(shí)發(fā)生的狀態(tài)，它的后邊又有一個(gè)for引導(dǎo)的從句來交代原因，而這個(gè)從句當(dāng)中有一個(gè)given，它起的實(shí)際上是一個(gè)定語從句的作用，用來修飾 descriptions，如果用從句來表達(dá)就是which had been given by people，而這個(gè)從句當(dāng)中由套著一個(gè)從句，是由who來引導(dǎo)的，用來修飾people，所以一個(gè)句子結(jié)構(gòu)不論有多么復(fù)雜，只要我們能把握連接詞，在句子當(dāng)中的作用，和意思，就不難理解。T:When reports came into London Zoo that a wild puma had been spotted。the puma was often observed at one place in the morning and at another place。Paw prints were seen…… puma fur was found clinging to bushes。As no pumas had been reported missing from any zoo in the countryT:當(dāng)英文中表示一個(gè)事實(shí)的客觀性的時(shí)候往往更多的使用被動(dòng)語態(tài)，這篇課文就是這樣，講的是美洲獅在各處出現(xiàn)并且被人目擊的情形，我們來看看被動(dòng)語態(tài)在課文當(dāng)中的使用：had been spotted，was …… observed，were seen……，was found clinging，had been reported missing這都是被動(dòng)語態(tài)最基本的構(gòu)成。另外was found clinginghad been reported missing 是在被動(dòng)語態(tài)之后加上現(xiàn)在分詞，起補(bǔ)充說明主語的作用T：right,That’s about the language point,我們知道了西方有收集動(dòng)物的人，在我們中國現(xiàn)在也有喂養(yǎng)寵物的人…… Step 3 Consolidation and homework T: Today we learned some new words and expressions , Who are they?
