问题补充：
Can you find me something ?
A. that I can open the tin
B. to open the tin
C. I can open the tin with
D. by which to open the tin
答案：
A. that I can open the tin
B. to open the tin
(答案→)C. I can open the tin with
D. by which to open the tin
解析： 本题考查定语从句。先行词是不定代词something，句意为：你能给我找到用什么打开罐头的东西吗？ open…with用什么打开……，所以选C I can open the tin with，关系代词that，省略了。
