In recent years there has been a significant decrease in their use, and conditions make their complete disappearance in the near future possible. Firstly, electric fans are far less effective in cooling a room. While the breeze they produce can feel pleasant, it does not lower the overall temperature. Not only do air conditioners achieve this, but their settings can be adjusted so that they can reach a specific, ideal temperature. Secondly, electric fans are often less efficient at the use of space, as they usually need to be placed on either the floor or a table; in contrast, air conditioners are usually hung on walls. But what do you think—will the electric fan soon be a thing of the past? Unit 3 Times change! 综合训练 外研版·选择性必修第二册 综合训练 一、单词拼写（根据句意及汉语提示写出单词）。 1.
