1. A.
   used to
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：金屬常用語制造機器和許多別的東西。is used for doing sth= is used to do sth 被用來做某事，故選B考點：use所構成句型用法
點評：be used to do sth被用來做某事；
be used to doing sth習慣于做某事及used to do sth過去常常做某事，是中考必須掌握的基本語言點。其中，used to do sth表示過去常常做某事而現(xiàn)在已經(jīng)不這樣了。
