辨析以下近义动词并选词填空：

翻译下句（重点判断该例句运用以上哪个词组？）

Part 2 Text
(1) (Ph1) Pumas are large, cat-like animals which are found in America.
l 单词：America 美洲
l 词组：cat-like adj. 像猫一样的
模仿：
an innocent girl: an angel-like girl
life-like 栩栩如生的
l 句型模仿：UFO是一种像盘子一样的巨型飞行物，在全世界都有发现。
UFOs are large, plate-like flying objects which are found all over the world.
l 阅读理解：对比标题和课文首句，分析选择文章结构走向：大→小 小→大
（课文第一句定义美洲狮，而标题中的美洲狮有限定成分，即at large, 从文章走势来看，下文写的是具体的一只美洲狮，而非笼统的，所以从大写到小【学生版不出现】）
(2) When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously.
l 词组：take sth. seriously = deal with sth. seriously 认真对待某事
l 语法：that引导的同位语从句，说明前面名词reports的具体内容
请区分以下从句类型：
The news that she heard is true. 她听到的消息是真的。定语从句
The news that she will go abroad is true. 她将出国这消息是真的。同位语从句
（【学生版不出现】：定语从句修饰的名词在定语从句中充当成分，而同位语从句则不充当成分）
l 句型亮点：在英语中，改变一切用“人”作主语的习惯，学会直接用“物”作主语，该句中用come into London Zoo代替people in London Zoo got the report
仿写：老师们收到消息，说取消这周的英语测试。
The news came to the teachers that the English test in this week will be cancelled.
(3) 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 similar.
l 单词：investigate v. 调查 investigation n.
l 词组：claim to have seen声称看到过
l 句型分析：the descriptions given by people who claimed to have seen the puma were extraordinarily similar找出此句中的主干部分：the descriptions were similar
l 亮点：英文句子强调灵活多变，可以把主语不同的小句子通过不同连词巧妙而紧密的连接，如本句中as引导时间状语从句，for引导原因状语从句，given by people 分词作后置定语，who引导定语从句，主干部分为experts felt obliged to investigate.
(4) (Ph2) 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. It immediately ran away when she saw it, and experts confirmed that a puma will not attack a human being unless it is cornered.
l 单词：confirm v. 证实，证明，确认
l 句型：will not和unless构成双重否定，比用will和only更加强调
模仿：外星人除非被打扰，不然是不会袭击人类的。
Aliens won’t attack human beings unless they are disturbed.
l 阅读理解：本段后两句话的逻辑关系：因果
(5) 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. 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.
l 阅读理解：本段体现了puma的一大特性：mobility（英文单词）
l 语法：划线部分在句中成分是：宾语
(6) Several people complained of ‘cat-like noises’ at night and a businessman on a fishing trip saw the puma up a tree. The experts were now fully convinced that the animal was a puma, but where had it come from?
l 词组：on a fishing trip在钓鱼的旅途中
相关：on the increase 在增加
on the match 比赛中
l 阅读理解1.原文be convinced可否替换成并sure等常规词？
（【学生版不出现】：sure主要是因为这些词主观性较强，而be convinced则注重客观，更符合说明文的特点）
阅读理解2. 在上文中puma存在的证据（或证人）有：a woman picking blackberries, a trail of dead deer and small animals, Paw prints, puma fur, ‘cat-like noises’, a businessman on a fishing trip
(7) 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 toescape. The hunt went on for several weeks, but the puma was not caught. It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside.
l 词组：sth. be in the possession of sb. = sth. belong to sb.
对比：sb. be in possession of sth.= sb. have sth.
词组：at large 在逃的
l 语言亮点：最后一句中的wild/dangerous和quiet形成对比
l 句型模仿：想到另一群生物从天上俯视我们确实令很多人感到担心和不安。
It is disturbing for us to think that some creatures are looking down at us from the sky.
Part 3 Critical thinking / Cultural background
思考：What do you think about the image of the zoo experts in this passage? Find some adjectives to support your ideas.
参考答案： not credulous, incompetent（无标准答案，学生能自圆其说即可）
