The first text book，________ for teaching English as a foreign language，came out in the 16th century．
A. having written
B. to be written
C. being written
D. written

Answer 1

答案D
因为主语the first text book与come out之间是动宾关系，所以只能用被动语态，故排除A．又因为to be written表将来，being written表正在进行，都与后句中的在16世纪出版相矛盾，所以选written．written是过去分词，表示被动和完成．
