它在吗用英语怎么说

"Is it on?" is a common way to ask if something is currently functioning or working.

This phrase likely originated from the idea of turning on a device or appliance, such as a light switch or television, by physically flipping a switch or pressing a button. When something is "on," it means that it has been activated and is able to perform its intended function.

Here are a few examples of this phrase in context:

"Is the TV on? I don't see any pictures."
(电视在吗？我看不到任何画面。)

"Is the microwave on? I can't hear it humming."
(微波炉在吗？我听不到它嗡嗡作响。)

"Is the oven on? I smell something burning."
(烤箱在吗？我闻到有什么东西在燃烧。)

"Is the computer on? I don't see anything on the screen."
(电脑在吗？我看不到屏幕上有任何东西。)
