英语it was the training__he had as a young men__made him such a,good engineer.
a.what,that
b.that,what
c.that,which

Answer 1

额，是不是还有没打的选项额。。
第一空是which或者that，第二空一定是that。。第一空先行词是training，定语从句，由that或者which引导。。第二问的that，和前面的it was是构成强调句型。。从去除不影响语序这一点可以看出。。
祝你好运~_~

Answer 2

第一空：定从（that/which he had）其中that做宾语，可省
第二空：主从（what made him……）前面的It做形式主语
故选B

Answer 3

正确答案应该是C
it was the training that he had as a young men which made him such a,good engineer.
