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.

节选《新概念英语3-A puma at large》

文章解读:

(1)a puma at large

这是本文的题目,非常的简短,但却不容易看懂。large在我们的印象中表示“大的”。但是在这个题目里,at large为介词短语作定语,修饰a puma。如果表示puma很大,正确的用法应该是a large

puma。at large是英语众多俚语中的一个。表示逍遥自在的;未捕获的。通常来形容具有一定危险性的人或事物。比如:

The disease is still at large. 疾病仍在蔓延(未控制)。

(2)cat-like 似猫的

cat-like是经由两个单词进行组合而成的词,由词根+后缀构成。因为后缀like就有相像的意思。所以这个单词就是像猫的。当然,如果需要,我们也可以写出dog-like的词。

(3)which引导的定语从句用法

在这里,不得不说定语从句是分限定性定语从句和非限定性定语从句。什么区别?先看一个例子:

① I have a brother who is an actor.

② I have a brother ,who is an actor.

两个句子唯一的区别就是第2句多了一个逗号。

这两个句子虽然都在说“我的兄弟是演员”,但潜台词却透露了家庭的背影信息。

①是限定性定语从句,潜台词是,我有很多兄弟,其中一个是演员。

②是非限定性定语从句,潜台词是,我只有一个兄弟,他是演员。

因为非限定性定语从句有逗号的关系,可以看成两句话,I have a

brother. He is an actor.

所以在这个文章中,Pumas are large, cat-like animals which are

found in America.中,which引导的定语从句就是限定性定语从句。表示“美洲狮是一种大型的似猫的动物,发现于美洲。

which在用于定语从句时,一般是用来指物。who或whom用来指人。

使用非限定性定语从句时,不仅可以来形容一个词,而且还可以来修饰一个句子。比如:

She is very fond of her daughter, Emily, which is natural. 她非常爱她的女儿Emily,这是很自然的。

在这个句子中,我们就不能看成which is natural是形容Emily。which在这个句子中,是代表着整个句子。形容妈妈爱女儿是一个很自然的事情。

①Pumas are large, cat-like animals which are found in

America. ②When reports came into London Zoo that a wild

puma had been spotted forty-five miles south of London,

they were not taken seriously.③However, 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.

文章解读:

今天学习第②句,更多内容请看往期:

When reports came into London Zoo that a wild puma had

been spotted forty-five miles south of London, they were

not taken seriously.

(1)when的用法

①在大家熟知的领域是when当疑问词使用。

When did you know about Webi closing his training course?

你是什么时候知道韦博关闭其培训班的事情的?

②在今天的要学的句子中,when做第二种用法。引导时间状语从句。

这里提到的时间,大家不要先入为主的认为就是8点啊,9点这样的时间。而是指当某个事件发生的那一刻,这样的时间节点。

The students panicked when they learned that Webi had

closed his training course. 当学生们知道韦博关闭其培训班时都很慌。

③when还可以引导定语从句

May is the month when we are most busy. 5月是我们最忙的一个月。

(2)同位语从句的用法

When reports came into London Zoo that a wild puma had

been spotted forty-five miles south of London……

在这个句子中,that从句为同位语从句的用法,作report的同位语,用来进一步说明报告的内容。

两样可以使用同位语的用法,比如可以使用逗号的方式。

He is there, near the window. 他在那边,在窗户附近。

使用冒号的方式:

We will visit two cities: Beijing and Shanghai. 我们将去两个城市:北京和上海。

也可以使用or的形式,such as,of等。

(3)take seriously 认真对待

they were not taken seriously中,they在这里代表前面提到的reports,有些同学会认为they只能表示他们/她们,其实还能表示它们。这也就不难理解能代表reports了。

I believe you will take seriously my advice into account.我想您会认真考虑我的建议的。
