问题 What a pity! Considering his ability and experience, he _________ better.
选项 A、needn’ t have done
B、must have done
C、couldn’t have done
D、could have done
答案 D
解析 本题为情态动词题。考查“情态动词+完成时”的用法。could + have done表示“本可能做却没有” ;must + have done只用于肯定句中，表示对过去情况的肯定推测,意为“想必，一定”;needn’t have done一般用于否定句，表示“本不必做的事情却做了”; couldn’ t have done表示“过去不可能做了某事”。句意:真遗憾!就他的能力和经验而论,他本可能做得更好的。D项符合句意,故选D。
