§ Lesson 1 A puma at large 逃遁的美洲狮
listen to the tape then answer the question
below. 听录音, 然后回答以下问题.
Where must the puma
have come from?
Pumas are large, cat-like
animals which are
found in America. When
reports came into
London Zoo that a wild puma
had been spotted
forty-five miles south of
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
extraordinarily similar.
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. 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.
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? 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
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.
【课文讲解】
at
large
1：逃遁的，没有被控制的。
2：详细的(in detail)
3：总体来讲（as a whole）
在英文的表达方式中，首先呈现给读者的是结果。写
议论文的时候要注意把握观点
L01-02 end 13’15”
L01-03 begin
13’09”
eg: Pandas are large cat-like
animals which are
found in Asia.
life-like
栩栩如生的
一般来讲定语从句和同位语从句紧随在被修饰名词后
面，但为了保持句子平衡，也
可以把谓语动词放到从
句之前
定语从句只是对于被修饰词的补充说明、修饰。
同位语从句则是讲述被修饰名词的内容
定语从句的引导词：
精品教学课件设计 | Excellent teaching plan
指人：主语 who; 宾语 whowhom; 定语
whose
表达事物：that(也可指人) which
时间状语：when; 地点状语：where;
原因状语：
why
同位语从句：名词做主语、宾语时，关系词用that
而
不是which
时间 when; 地点 where
eg: An
idea came to her that she might do the
experiment in another way.
I have no idea
what has happened to him.
定语从句中没有what
这个关系词，但它可以引
导同位语从句
(An idea)…come to
sb.某人突然想到了……
take sth. seriously==deal
with sth. seriously
认真（严肃）对待某事
take sth.
lightly: 草率对待某事
as 随着
过去分词做定语
声称曾经作过某事： claim to have done sth
I still remember the school where I studied
English.
L01-03 end 13’09”
L01-04 begin 11’49”
confirm: be
sure, be certain
search=hunt
把某物留在后面：leave
behind
Wherever he went, the wound soldier
left
behind him a trail of
blood.伤员所到之处，都留下
道道血迹。
英文的表达方式重点在于突出客观事实，而中文则善

on +
名词：强调动作正在进行
on the rise:在上升
on the
increase: 在增加
on the watch: 在观看
on the
