一、物理意义上的“拆除”、“摧毁”

1. 拆除建筑物

当pull down用于描述拆除建筑物时,通常是指将建筑物、构筑物等从地面上移除。这个动作可能是为了改建、扩建或是因为建筑物已经破旧不堪。例如:

The old factory will be pulled down to make way for a new shopping center.

(这座旧工厂将被拆除,以便为新购物中心腾出空间。)

2. 摧毁障碍物

Pull down还可以表示拆除或摧毁道路上的障碍物,如围墙、栅栏等。例如:

The villagers decided to pull down the wall that had blocked the entrance to their village for years.

(村民们决定拆除多年来一直堵住他们村子入口的那堵墙。)

二、抽象意义上的“降低”、“削弱”

1. 降低价格

Pull down在抽象意义上可以表示降低价格、水平或标准。例如:

The company had to pull down the prices of its products due to increased competition.

(由于竞争加剧,该公司不得不降低产品价格。)

2. 削弱力量或影响

Pull down还可以表示削弱某人或某物的力量、影响或地位。例如:

The scandal pulled down the politician's reputation, and he was forced to resign.

(这场丑闻削弱了这位政治家的声誉,他被迫辞职。)

三、其他用法

1. 拉下窗帘

Pull down还可以表示拉下窗帘、百叶窗等。例如:

Please pull down the blinds to block the sunlight.

(请拉下百叶窗挡住阳光。)

2. 取下衣物

Pull down还可以表示从衣架、挂钩等地方取下衣物。例如:

在网络用语中,pull down可以表示下载文件、数据等。例如:

四、注意事项

1. 与tear down的区别

虽然pull down和tear down都可以表示拆除建筑物,但两者在语气和侧重点上有所不同。Pull down更侧重于物理上的拆除,而tear down则带有更强烈的情感色彩,表示彻底摧毁。例如:

The old building was torn down by the demolition team.

(那座旧建筑被拆除队彻底摧毁了。)

2. 与bring down的区别

Pull down和bring down都可以表示降低或削弱,但bring down更侧重于使某人或某物陷入困境或失败。例如:

The heavy rain brought down the power grid, leaving thousands of people without electricity.

(大雨使电网瘫痪,导致数千人断电。)
