[简答题]
For many women choosing whether to work or not to work outside their home is a luxury: they must work to survive. Others face a hard decision. Perhaps the easiest choice has to do with economics. One husband said, "Marge and I decided after careful consideration that for her to go back to work at this moment was an extravagance (奢侈) we couldn’t afford."

The most important aspects of the decision have to do with the emotional needs of each member of the family. It is in this area that husbands and wives find themselves having to face many confusing and conflicting feelings. There are many women who find that homemaking is boring or who feel imprisoned (被囚)if they have

[单项选择]The war was the most peaceful period of my life. The window of my bedroom faced southeast. My mother had curtained it, but that had small effect. I always woke up with the first light and, with all the responsibilities of the previous day melted, felt myself rather like the sun, ready to shine and feel joy. Life never seemed so simple and dear and full of possibilities as then.

At least Mrs. Right did; she easily showed her feelings, but I didn’t have the same control of Mrs. Left, so she mostly contented herself with nodding agreement.
They discussed what Mother and I should do during the day, what Santa Claus should give a fellow for Christmas, and what steps should be taken to brighten the home. There was that little matter of the baby, for instance. Mother and I could never agree about that. Ours was the only hou
