Part IV Short Answer Questions
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." With two preschool children, it soon became clear in their figuring that with babysitters (临时照看小孩的人), transportation, and increased taxes, rather than having more money, they might actually end up with less.
Economic factors are usually the first to be considered, but they are not the most important. 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 (被囚禁) if they have to stay home with a young child or several children. On the other hand, there are women who think that homemaking gives them the deepest satisfaction.
From my own experience. I would like to suggest that sometime the decision to go back to work is made in too much haste. There are few decisions that I now regret more. I wasn't mature enough to see how much I could have gained at home. I regret my impatience to get on with my career. I wish I had allowed myself the luxury of watching the world through my little girl's eyes.

Even plants can run a fever, especially when they're under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3, 000 feet away - straight up. A decade ago, adapting the infrared (红外线) scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (杀虫剂) spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest (害虫) problems.
注：1.文章首句提出问题：植物受到病虫害侵扰会发烧
2.straight up 高空
3.adapt 使用，适用
4.come up with 提出（方案、计划）
5.precisely 准确的、精确的
6.spray 喷射
Even better, Paley's Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running "fevers". Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
