While he was investigating ways to improve the telescope, Newton made ______ discover which completely changed ______ man’s understanding of colour.A. a；不填 B. a；the C. 不填；the D. the；a選A。discover應該是discovery吧？？當表示人類，人的時候呢，就要用單數(shù)，而且不加冠詞。

A對.第一個空中，可數(shù)名詞單數(shù)前必須又冠詞，拿答案是A或D，而understanding是動名詞，不可能加冠詞a,這樣排除D.所以答案剩A.
