When reports came into London Zoo that a wild puma had been spotted forty-five miles south of

4、London ,they were not taken seriously. 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 extraordinary similar. The hunt for the puma began in a small village where a woman picki

5、ng blackberries saw a large cat only five yards away from her. It immediately ran away when she saw it, and experts confirmed that a puma will not attack a human being unless it is cornered. The search proved difficult, for the puma was often observed at one place in the morning and at another place

6、 twenty miles away in the evening. Wherever it went, it left behind it a trail of dead deer and small animals like rabbits. Paw prints were seen in a number of places and puma fur was found clinging to bushes. Several people complained of cat-like noises at night and a businessman on a fishing trip

7、saw the puma up a tree. The experts were now fully convinced that the animal was a puma, but where had it come from? As no pumas had been reported missing from any zoo in the country, this one must have been in the possession of a private collector and somehow managed to escape. The hunt went on for

8、 several weeks, but the puma was not caught. It is disturbing to think that a dangerous wild animals is still at large in the quiet countryside.at large 为介词短语，作定语，修饰 a puma. eg, The woman in black in his mother. Experts from the Zoo began their investigation.At large 逍遥自在的，行动自由的；未捕获的。 通常用来指具有危险性的人或事

9、物未被控制的状态： the escaped murderer at large The disease is still at large. 这种疾病仍在蔓延。Cat-like 为派生词，由词根【名词】+后缀【-like】构成。 后缀-like 表示“像似的”、“有特征的”： dog-like woman-likeThat 从句为同位语从句，作reports 的同位语，进一步说明报告的内容。此类结构直接用于某些名词。类似的有：ides, fact, news, hope, thought, proof, message等，eg. There can be no doubt that she i

10、s qualified for the job.毫无疑问，她胜任这项工作。However 并列连词，用来表示语义上的转折，如：The task is a bit difficult. It is, however, not beyond their reach.这个任务是有点难，但并非他们无力来完成。As 从属连词，在此引导时间状语从属连词，在此引导时间状语从句，表从句，表“随着随着”、“当当.时时”，如：如： As she talked on she got more and more worried.她越说越着急。她越说越着急。Oblige 表示“迫使”之意时，后接表示人称的宾语和一动词不

11、定式构成的复合宾语： oblige sb. to do sth. 迫使某人做某事。文中用于被动语态：be/ feel obliged to do sth. 被迫做某事。如：The police obliged the onlookers to leave.警察迫使围观者离开。 He felt obliged to let her in. 他只得让她进来。For 并列连词，表示因果关系，通常用来引导一事后想到的原因，类似于括号内的说明性文字。所以不可置于句首:如：For I was feeling quite hungry, I decided to stop and have lunch.(错

12、)I decided to stop and have lunch, for I was feeling quite hungry.(对)Who 引导的定语从句，修饰其前的people. to have seen 为动词不定式的完成时结构，表示动词不定式的动作发生在谓语动词claimed之前.Picking blackberries 为现在分词作定语，后置修饰woman.现在分词/分词短语作定语时含有进行、持续和主动的含义，因此可将其译为一位正在采摘黑莓的妇女，eg. Tell those children playing outside not to make so much noise.让

13、在外边玩耍的孩子别这么吵。Will 在此不表示将来时的助动词，而表习惯性或动作特征的情态助动词，表示“就”、”就会”、“总会”Eg: He will never let anybody know what he is doing. 他从不让任何人知道他在干什么。Twenty miles away 为定语，修饰place. 表地点：the way ahead 前面的路his trip abroad 他的出国旅行the sentence below 下面的句子 表时间： the meeting yesterday their stay overnight Found clinging to bus

14、hes 中的clinging to bushes 为现在分词短语，此处作主语puma fur 的主语补足语。作补足语使用的分词结构常见于 see， hear, notice, watch, keep, find, get, have, feel. Smell等动词之后，如： Did you smell something burning? She could feel her heart beating violently. 加不带to 的动词不定式，表所做动作的全过程。I saw her cross the road.我看见她穿过了马路。现分表动作的部分过程.I saw her crossi

15、ng the road.我看见她正在过马路Cling to 表：粘在.上。还表：坚持，萦绕于The odour clung to the great hall.那气味在大厅里经久不散。His friends last words clung to his memory.他朋友的最后一句话一直萦绕在他的脑海里。Complain 抱怨；诉苦。作vi.时，complain about/of 抱怨/埋怨： complain to sb. about/ of 向某人抱怨/埋怨，如：You indeed have nothing to complain of.Shes now complaining to

16、 the manager about the service.作vt.时，complain that 从句 She complained that he had always been rude to her.Must have been 对过去事情的推测You must have seen him yesterday.The lights have gone out. A fuse must have blown.但在疑问句和否定句中表示对过去事情的推测时用can和cant:I dont think he can have heard you. Call again.Where can Jo

17、hn have put the matches? He cant have thrown them away.be in the possession of 属于；为所有。被动，主语应为物；be in possession of 拥有，主动，主语为人。He was born in New York, while the city was still in the possession of the British troops. The chief was in possession of a large quantity of stolen property.那个头目占有大量偷盗来的财产。

18、It is disturbing to think thatIt 为先行词，起形式主语的作用，句子的逻辑主语是后面的动词不定式。如：Its difficult to understand what shes talking about.Its no use talking to him about it.It was really astonishing that she refused to talk to you.Key structures and usage简单句，一般有一个限定动词。如We sang all night.并列句，几个简单句连接起来。However, and, so, but, yet, as far as， ect.We fished all day, but didnt catch a thing.复合句,组成的句子并非同等重要。主从句The alarm was raised as soon
