名詞light的三類用法及搭配習(xí)慣

一、表示“光線”“亮光”，一般為不可數(shù)名詞；表示“在……亮光下”，可用介詞 in 或 by。其區(qū)別是：用 in 通常只客觀地表示“在……亮光下”，而用 by 則暗示“憑借亮光做……”之意。如：

They went out for a walk in the moonlight. 他們在月光下到外面散了步。

He worked by the light of the moon. 他在月光下工作（即憑借月光工作）。

The light is too weak to read by. 光線太暗不能看書。

二、表示“燈”，注意搭配：

The light is [goes] out. 燈熄了。

The light is [comes, goes] on. 燈亮了。

He turned [switched, put] on the light. 他打開燈。

He turned [switched, put] off the light. 他關(guān)掉燈。

三、表示“火”，通常只指抽煙用的“火”，注意不要與 fire 弄混。如：

能借個火嗎?

誤：Have you got a fire, please?

誤：Can you give me a fire, please?

正：Have you got a light, please?

正：Can you give me a light, please?
