该题说来自一位皇室朋友的一万颗钻石在白金汉宫展出，而录音内容说的是 钻石是女孩“ 最好的朋友” （ diamonds are girls’ best friends），意思是最适合女孩佩戴，所以正确答案为B。解题需要理解在diamonds are girls’ best friends这个词组中 diamonds前没有冠词，diamonds在这里通指钻石，而不是所展出的一万颗钻石。

[重点难点]
对冠词保持敏感，把握、区分名词有无冠词时的意义差异。

[录音原文]
Ten thousand diamonds have made themselves into the limelight at the Buckingham Palace for a public display. With complex designs, each had an intriguing history before it became a royal treasure. It is said that diamonds are girls， best friends， and royalty, over the years, has struck up quite a friendship with these stones.
