问题描述：
The first textbook__for teaching English as a foreign language came out in the 16th century.
A.have written B,to be written C.being written D.written
不能选B吗?前面不用加谓语吗?不是 is written吗?
答
句子主语为The first textbook came out in the 16th century.如果写is written，则句中会出现两个谓语：came和is;因此不能再出现谓语。这本书是在16世纪写的，属于过去，因此只能为D，B项表示还没写并有打算写。
答
句中谓语只能有一个,最明显的,一个是be动词,一个是动词.
1.上句中,明显的动词是came .所以不能用 is written.
2.此处,D written for teaching English as a foreign language 作为text 的定语,book 与 wirte 的关系是被动的,书被写,不选B因为,全句谓语是Came （come 的过去式）,著书时间为16世纪,而B表示动作尚待实施,表示将来的动作,故而不符.
