第三部分阅读理解(共20小题;每小题2分,满分40分)

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。

Looking back at my school yearbooks of the 1970s, 80s, and 90s, I find the style of uniform says a lot about the students and the character of the times. In the 1970s, students accessorized (配饰) their uniforms with platform shoes. During the 80s, hair was huge—literally. Students’ goofy hair filled up nearly every shot in the yearbook. In the 90s, accessories were all the rage (流行).

Uniform rules have always been strict. The restrictions (限制) are down to the inch: Gray or plaid skirts must be no shorter than two inches above the knee; a red, green, navy or white polo must be worn at all times; and only white, blue, black, and gray sneakers or flats are allowed. With all these rules, one can’t help but wonder how the typical rebellious (叛逆的) teenager can express her individuality.

Still, they manage. Senior Michelle Ferrier says she accessorizes by wearing bright colors like green and pink in bracelets, shoe laces, and headbands to stand out and be fashionable. For any stylish (时尚的) Carondelet student, accessories are key.

At Carondelet, one thing’s for sure: The older a student gets, the more she’s willing to bend the rules. Senior Natalia Piwek admits that she often pairs her “tights and colorful socks” with “illegal shoes”. If you happen to see a girl with colorful tights or boots running across the hallway, it’s most likely that she’s running from a dean.

In about two months, I will say goodbye to my uniform. I will miss the convenience of wearing it. However, I must say, wearing a uniform has taught me an important lesson that I will take with me when I go off to college: it doesn’t matter what you wear, but how you wear it. And how you carry yourself.
