　　4.The hunt for the puma began in a small village where a woman picking blackberries saw 'a large cat' only five yards away from her.

　　语言点1 where引导定语从句，修饰village。

　　语言点2 搜索：hunt，search。

　　语言点3 the hunt for sb./sth.抓捕某人/某物。hunt for a job找工作，Missing Wanted寻人/寻物启事，People Search/Wanted/Missing寻人，Wanted通缉。

　　5.It immediately ran away when she saw it, and experts confirmed that a puma will not attack a human being unless it is cornered.

　　她刚看见它，它就立刻逃走了。专家证实，美洲狮非被逼得走投无路，是决不会伤人的。

　　语言点1 when引导时间状语从句，and连接两个并列分句，第二个分句中的that引导宾语从句，说明confirm的内容，unless引导条件状语从句。

　　语言点2 1）corner作动词常用于被动语态：sth./sb. be corned某人/某物被逼入绝境

　　 2)与corner搭配的介词at the corner of the street在街道的拐角in the corner of the room在房间的角落里on the corner of the desk在桌子的一角

　　语言点3 1）unless和if...not均表示否定的条件，一般可互换：Unless you have more pratice,you will fail in the dtiving test.=If you do not have more pratice,you will fail in the dtiving test.

　　语言点4 写作模板:The teacher told him that he would never pass the examination unless he studied hard.

　　6.The search proved difficult, for the puma was often observed at one place in the morning and at another place twenty miles away in the evening.

　　语言点1 句子中含有一个for引导的原因状语从句。特别注意的是：地点状语at one place 和at another place，时间状语in the morning 和in the evening形成对照。

　　语言点2 because和for的区别：because知道上的或自然的原因，语气较强，for多指逻辑上的判断。比较：Itmust have rained,for the river is so high.He must be at home,for the light in his room is on.

　　语言点3 twenty miles away做后置定语，修饰place。地点副词和时间副词做后置定语：the house ahead前面的房子，the conclusion below下面的讨论，the plan last year去年的计划。

　　7.Wherever it went, it left behind it a trail of dead deer and small animals like rabbits.

　　语言点1 wherever引导地点状语从句。

　　语言点2 where/wherever区别：where引导从句表示特定地点，而wherever引导从句表示非特定地点。比较下面两句：He must go where we send him.=He must go to the place where we send him.

　　He must go wherever we send him.=He must go to any place where we send him.

　　语言点3 it left behind it a trail of dead deer...这部分中，a trail of dead deer and small animals like rabbits与behind it形成倒装。一般而言，倒装的用法有两个作用：强调或平衡句子。本句是为了平衡句子。倒装是很重要的写作手法，在新概念英语系列中还有很多，例When they got home，Jane cooked their dinner in the microwave oven and without relising it,cooked her fiance's wallet as well.

　　8. Paw prints were seen in a number of places and puma fur was found clinging to bushes.
在许多地方看见了爪印，灌木丛中也发现了粘在上面的美洲狮毛。

　　语言点1:句子结构分析:这是一个由and连接的并列句，意思层层递进，说明美洲狮逃遁的充分证据。Clinging to bushes为现在分词短语，作主语puma fur的补足语，补充说明主语的状态。

　　例句支持:

　　I found a tagboard clinging to my luggage.
我发现我的行李上挂着一张标签纸。

　　语言点2:作者接连列举了美洲狮身上的两种特有的东西，并使用了被动语态，完美地呈现了英语语言的特色。

　　原文句子:Paw prints were seen in a number of places and puma fur was found clinging to bushes.
对比:People saw paw prints in a number of places and found puma fur linging to bushes.

　　总结:可以看到，如果使用主动语态，则美感全无。

　　例句支持:

　　A note was passed up to the speaker.有人给演讲者递上来一张纸条。
对比:Some one passed up a note to the speaker.（主动语态，强调“人”，不突出“纸条”。）

　　语言点3:由短语a number of还可以进一步引申出下面用于写作的短语:越来越多的

　　（1） an increasing number of：An increasing number of students have realised the importance of English application,越来越多的学生已经意识到了英语应用的重要性。
（2） a growing number of：Now,a growing number of Chinese students go abroad for study.现在越来越多的中国学生去海外留学。
