2. B.
   is used for
3. C.
   is used as
4. 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。
