1. A.
   used to
2. B.
   is used for
3. C.
   is used as
4. D.
   is used to

Answer 1

B
解析：
试题
分析：句意：金属常用语制造机器和许多别的东西。is used for doing sth= is used to do sth 被用来做某事，故选B考点：use所构成句型用法
点评：be used to do sth被用来做某事；
be used to doing sth习惯于做某事及used to do sth过去常常做某事，是中考必须掌握的基本语言点。其中，used to do sth表示过去常常做某事而现在已经不这样了。
