问题 According to the passage, the modern world can be described as the following EXCEPT ______.
What’s the main idea of this passage?

选项 A、High-tech life may be risky.
B、It’s difficult to make friends in the modern world.
C、Juvenile crime is rising in Japan.
D、More electronic pets are turned out.

答案A

解析 文章首段即提出本文的主题——potentially lethal dangers,然后再第2段通过举例说明这种危险与高科技之间的关系,接着文章介绍了几种高科技产品,从倒数第4段开始,文章再次回到了高科技所引发的问题,由此可见,本文的主旨是为了说明在高科技的社会也存在危险,即选项A为本题答案。选项B是对文章末段的概括,但这并不是文章主题,而是在文章主题的主要内容的基础上做出的推测;选项C和D都是文中提到的某个细节,并非主旨。
