第10题
It seems that beauty and women are twins. Observe for yourself. Ads on fashion flood TV sc
reen, radio programs, magazines and the streets. Whether they have realized or not, women are besieged (包围) by a sea of fashion. They are taught to think that without beautiful clothes they will grow old and lose their charm. So who dares to neglect dressing up at the cost of their appearance and youth?

But I do not agree with the opinion that women have to show their beauty through their looks. The richness of their mind proves to be more beautiful and attractive than their looks. A woman who has experienced many troubles and may be called "aunt" or "granny" can still maintain her beauty if she has such excellent qualities as knowledge, ability, a kind heart and concern for others.

In addition, old and young, beautiful and ugly are relative concepts. People who keep a young mind will never feel old. Curious about new things and eager to learn more, they keep up with the tide. Plainly dressed women may have a type of beauty, which is pure and real.

Reading and learning is the best way to keep one youthful. Good books are fertile soil which can feed the flower of one's heart and looks.

Why does the author say that beauty and women are twins?

A.Women are born to be beauties.

B.Women like to show off their beauties

C.Women are proud of their beauty

D.Women try to maintain their beauty by dressing up
