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. Plants will emit an increased amount of heat when they are______________.

Americans can travel almost anywhere they choose. But to protect its people, the government lists a few dangerous places where Americans cannot go. These places are unfriendly countries or countries at war. There, the traveller might not be safe. These countries are listed in a small book called a passport（护照）.
This passport is a government request for the safety of its travelling people. It is also a government’s pledge（保证） that the people will obey the rules of the host country（东道国）.
To receive a passport from the government, a traveller must prove that he is an American citizen （公民）. An American can not go overseas（外国） without a passport. Only certain close countries such as Canada and Mexico do not ask for passports.
Pasted （粘贴）inside the passport is the traveller’s picture. Children travelling with their parents are included in one parent’s book.
Thousands of people from the United States visit other countries every year. An American traveller might carry plane tickets, money, clothing and many other things. But the most important that he carries in another country is his passport.

Language is always changing. In a society where life continues year after year with few changes, the language does not change, either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.
There are several major language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language About 3 percent of the people in the world speak languages that are not in these major families.
60. The early language had ______.
A. a lot of problems B. words and easy grammar
C. words but no grammar D. grammar but not many words
61. In the next few hundred years we can expect language to ______.
A. stay exactly the same B. change a great deal
C. change only a little D. add more words and drop some grammar
62. What this article shows is that ______.
A. languages change fast B. languages really don’t want to change
C. language changes with changes of society D. Spanish and English change
63. From this article we can see that ______.
A. language can change very slowly or very quickly
B. if we don’t change, then our language won’t change, either
C. we should give our plants new names
D. English and Spanish are the only languages that have changes
No one is glad to hear that his body has to be cut open by a surgeon（外科医生） and part of it taken out． Today， however， we needn't worry about feeling pain during the operation． The sick person falls into a kind of sleep， and when he awakes， the operation is finished． But these happy conditions are fairly new． It is not many years since a man who had to have operation felt all its pain．
Long ago， operation had usually to be done while the sick man could feel everything． The sick man had to be held down on a table by force while the doctors did their best for him． He could feel all the pain if his leg or arm was being cut off， and his fearful cries filled the room and the hearts of those who watched．
Soon after 1770， Josept Priestley discovered a gas which is now called “laughing gas”．Laughing gas became known in America．Young men and women went to parties to try it． Most of them spent their time laughing，but one man at a party，Horace Wells，noticed that people didn't seem to feel pain when they were using this gas．He decided to make an experiment on himself．He asked a friend to help him．
Wells took some of the gas，and his friend pulled out one of Well’s teeth．Wells felt no pain at all．
As he didn't know enough about laughing gas， he gave a man less gas than he should have． The man cried out with pain when his tooth was being pulled out．
Wells tried again，but this time he gave too much of the gas，and the man died．Wells never forgot this terrible event．
56.It is ___________since a man being operated felt all the pain.
A.a few more years B.not long C.few years D.two thousand years
57.Long ago, when the sick man was operated on, he___________.

58.Using the laughing gas, the people did not seem to___________.
A.be afraid of anything B.feel pain C.want to go to the parties D.be ill
59.If a man took less laughing gas than he should have when an operation went on he___________.
A.felt nothing B.felt very comfortable C.still felt pain D.would die

The key to happiness is how quickly you can get back your focus on what’s important.

Sixteen years ago I learned this lesson in the back of a New York City taxi cab. Here's what happened. I hopped in a taxi, and we took off for Grand Central Station. We were driving in the right lane when, all of a sudden, a black car jumped out of a parking space right in front of us. My taxi driver slammed on his brakes, skidded, and missed the other car’s back end by just inches!
The driver of the other car, who almost caused a big accident, started yelling bad words at us. My taxi driver just smiled and waved at the guy. And I mean, he was friendly. So, I said, "Why did you just do that? This guy almost ruined your car and sent us to the hospital!" And this is when my taxi driver told me what I now call "The Law of the Garbage Truck."
Many people are like garbage (rubbish) trucks. They run around full of garbage, full of frustration, full of anger, and full of disappointment. As their garbage piles up, they need a place to dump it. And if you let them, they'll dump it on you. When someone wants to dump on you, don't take it personally. You just smile, wave, wish them well, and move on. You'll be happy you did.
I started thinking, how often do I let Garbage Trucks run right over me? And how often do I take their garbage and spread it to other people at work, at home, or on the streets? It was that day I said, "I'm not going to do anymore."
Good leaders know they have to be ready for their next meeting. Good parents know that they have to welcome their children home from school with hugs and kisses. Leaders and parents know that they have to be fully present, and at their best for the people they care about. The bottom line is that successful people do not let Garbage Trucks take over their day. What about you? What would happen in your life, starting today, if you let more garbage trucks pass you by? Here's my bet. You'll be happier. Life's too short to wake up in the morning with regrets. So, Love the people who treat you right. Forget about the ones who don't.
