Question

Metal ______making machines and many other things.

A．used to

B．is used for

C．is used as

D．is used to

Answer 1

B

解析試題分析：句意：金屬常用語(yǔ)制造機(jī)器和許多別的東西。is used for doing sth=" is" used to do sth 被用來(lái)做某事，故選B
考點(diǎn)：use所構(gòu)成句型用法
點(diǎn)評(píng)：be used to do sth被用來(lái)做某事；be used to doing sth習(xí)慣于做某事及used to do sth過(guò)去常常做某事，是中考必須掌握的基本語(yǔ)言點(diǎn)。其中，used to do sth表示過(guò)去常常做某事而現(xiàn)在已經(jīng)不這樣了。
