[单项选择]Many people catch a cold in the springtime and / or fall. It makes us wonder.., if scientists can send a man to the moon, why can’t they find a cure for the common cold. The answer is easy.

[单项选择]One of the good things for men in women’s liberation is that men no longer have to pay women the old fashioned courtesies.
In an article on the new manners, Ms. Holmes says that a perfectly able woman no longer has to act helplessly in public as if she were a model. For example, she doesn’t need help getting in and out of cars, "Women get in and out of cars twenty times a day with babies and dogs. Surely they can get out by themselves at night just as easily."
