　　Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3, 000 feet away - straight up. A decade ago, adopting 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.

　　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.

　　The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only ff Paley finds the financial backing which he failed to obtain 10 years ago.

　 Kids will often ignore your requests for them to shut off the TV，start their chores(杂事)，or do their homework as a way to avoid following your directions.Before you know it，you’ve started to sound like a broken record as you repeatedly ask them to do their assignments，clean their rooms，or take out the trash.Rather than saying “Do your chores now.” you’ll be more effective if you set a target time for when the chores have to be completed.So instead of arguing about starting chores，just say，“If chores aren’t done by 4 pm，here are the consequences.”Then it’s up to your child to complete the chores.Put the ball back in their court.Don’t argue or fight with them，just say，“That’s the way it’s going to be.”It shouldn’t be punitive(惩罚性的)as much as it should be persuasive.“If your chores aren’t done by 4 pm，then no video game time until chores are done.And if finishing those chores runs into homework time，that’s going to be your loss.”On the other hand，when dealing with homework，keep it very simple.Have a time when homework starts，and at that time，all electronics go off and do not go back on until you see that their homework is done.If your kids say they have no homework，then they should use that time to study or read.Either way，there should be a time set aside when the electronics are off.

　 When a kid wears his iPod or headphones when you’re trying to talk to him，make no bones about it；he is not ignoring you，he is disrespecting you.At that point，everything else should stop until he takes the earplugs out of his ears.Don’t try to communicate with him when he’s wearing headphones—even if he tells you he can hear you.Wearing them while you’re talking to him is a sign of disrespect.Parents should be very tough about this kind of thing.Remember，mutual respect becomes more important as children mature.

　 A.avoid direct ways of punishment

3.When the kid is doing his homework，parents　　　　 .

　 A.should provide him with a good learning environment

　 B.can do whatever they like
