[命题点一]
—What are they used for —They are used for seeing in the dark.——它们是用来做什么的 ——它们是被用来在黑暗中照明的。
◎观察思考:
I'm used to reading English in the morning. 我习惯在早上读英语。
Plastic is used to make bags. 塑料被用来制作塑料袋。
The girl used to take a walk after dinner. 这个女孩过去常常在晚饭后散步。
◎用法总结:(1)be used for意为“(某物)被用作……”,其后接名词、代词或动名词。be used for doing sth. 相当于be used to do sth.,句子的主语通常是物。例如:
This kind of special material is used for making dresses. =This kind of special material is used to make dresses. 这种特殊的材料是用来做裙子的。
(2)“used to+动词原形”表示“过去常常做某事(现在不再做了)”。
(3)be used to doing sth.表示“习惯于做某事”。to是介词,后面跟名词或动名词形式。例如:
His mother is used to getting up early.他的妈妈习惯于早起。
