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(***虫剂)spraying rather than
rain poison on a whole field, which invariably includes plants that don"t have pest 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 colourcoded map showing where plants
were running "fevers". Farmers could then spotspray, 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 longterm 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 if Paley finds the financial backing which he failed to obtain
10 years ago.
1. Plants will send out an increased amount of heat when they are________.
A. facing an infrared scanner
B. sprayed with pesticides
C. in poor physical condition
D. exposed to excessive sun rays
2. In order to apply pesticide spraying precisely, we can use infrared scanning to________.
A. estimate the damage to the crops
B. draw a colourcoded map
C. measure the size of the affected area
D. locate the problem area
3. Farmers can save a considerable amount of pesticide by________.
A. resorting to spotspraying
B. transforming poisoned rain
C. consulting infrared scanning experts
D. detecting crop problems at an early stage
4.The application of infrared scanning technology to agriculture met with some difficulties-________.
A. its high cost
B. the lack of official support
C. the lack of financial support
D. its failure to help increase production
5. Infrared scanning technology may be brought back into operation because of________.
A. full support from agricultural experts
B. growing concern about the excessive use of pesticides on crops
C. the forceful promotion by the Department of Agriculture
D. the desire of farmers to improve the quality of their produce

举一反三
20th century. So far, only two countries in the world, the USA and France, have ever produced them.
But these fearful fighting machines are about to enter Asia.
The US Navy said last month that one of its nine nuclearpowered aircraft carriers will be sent to
Japan to replace the diesel(柴油)powered carrier Kitty Hawk in 2008. In an agreement on October
30, the two countries also planned to level up their military (军事的) cooperation and the USA called
for Japan to take a larger role in alliance military moves.
It will be the first time that a nuclearpowered carrier is based in Japan. Bombed by US forces in
World War ? at Hiroshima and Nagasaki, Japan is the only world country to have been attacked by
a nuclear weapon. Therefore, the citizens are highly sensitive to where nuclearpowered weapons are
based.
"A radiation leak at Yokosuka would kill 100,000 people as far away as Tokyo, and could cause
billions of dollars in damage, " said Masahiko Goto, leader of a protest group in Yokosuka. His group
has collected more than 300,000 signatures of people across Japan opposed to the nuclear carrier.
The 44yearold Kitty Hawk, the US Navy"s oldest active ship, has been based in Yokosuka since
1998. It had returned to the US to be decommissioned in 2008. The new carrier, yet to be unveiled,_
will travel faster, be capable of supporting longer operations and carry with it the Navy"s most modern
technology.
Experts pointed that this change is not only to strengthen the USJapan military alliance but also to
keep the military power of China and North Korea within limits. However, even Japanese experts don"t
believe that the two countries are threats to the region.
"There is no need for Japan to have a nuclear carrier as defense, " said Tetsuo Maeda, an
international relations professor at Tokyo International University. He said that the change of ship
indicates an increased military capability in the region, much more than what is needed.
1. With such a formidable weapon to enter its country, Japanese citizens ________.
A. are aware of its benefits to the country
B. are anxious about its potential danger
C. are curious about the advanced technology
D. are against where the carrier will be based
2. The replacement of the aircraft carrier is intended to________.
A. set up a kind of base in Japan
B. strengthen the USJapan military alliance
C. show Japan"s greater military capability
D. get rid of the dated marine weapon
3. From the story, we learn that________.
A. no other countries except the USA and France possess aircraft carriers
B. Japan has long planned to increase its military capability with new weapons
C. Japan will be the first country in Asia to have a nuclear aircraft carrier
D. Japan will be the third country to produce a nuclearpowered aircraft carrier
4. The underlined word "unveiled" in the fifth paragraph probably means________.
A. perfected
B. discussed about
C. produced
D. brought to view
5. By his remark in the last paragraph, the professor means that________.
A. he is quite confident of their military defense
B. he is completely opposed to a new nuclear carrier
C. what is needed is far more than a nuclear carrier
D. it is unnecessary to guard against the two countries
known as jet lag. Jet lag results from flying long distances in an airplane. People with jet lag feel
extremely tired for several days. They may also have problems in thinking clearly and remembering.
Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study,
which involved twenty women who worked for international airlines. They had served passengers on
airplanes for five years. These flight attendants flew across many countries and at least seven time zones.
In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women
spent five days or fewer in their home areas between long flights. The other half spent more than fourteen
days in their home areas.
The researcher took some saliva from the women"s mouths to measure levels of a hormone (荷尔
蒙 ) that increases during stress . He tested them to see if they could remember where black spots
appeared on a computer screen .And he took pictures of their brains to measure the size of the brain"s
temporal lobes. (脑叶).
It was found that the women who had less time between flights had smaller right temporal lobes. This
area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels
of stress hormones.
The researcher believes the brain needs at least ten days to recover after a long trip. He says airline
workers told him their ability to remember got worse after working on planes for about four years. Other
studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that
controls memory.
Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find ou
t if too much jet lag could permanently affect memory.
B. can make people feel tired for a few weeks
C. can be only found in flight attendants
D. can be caused by flying over several time zones
B. scientists fear that this research is not done properly
C. every scientific conclusion needs the support from many tests
D. the women who were examined in the research were not healthy
B. the women who fly in short time have smaller right temporal lobes
C. the women who have longer flights fail the memory test
D. the women who rest more than 14 days produce less hormones
B. A story of a group of flight attendants.
C. The importance of having enough rest after flights.
D. A research about the effects of jet lag on the brain.
entertain themselves, after engineers in Japan developed a musical road surface.
A team from the Hokkaido Industrial Research Institute has built a number of "melody roads", which
use cars as tuning forks(音叉)to play music as they travel.
The concept works by using grooves(凹槽). They are cut at very specific intervals in the road
surface. The melody road uses the spaces between to create different notes.
Depending on how far apart the grooves are, a car moving over them will produce a series of high
or low notes, and designers are able to create a distinct tune.
Patent documents for the design describe it as notches(刻痕) "formed in a road surface so as to
play a melody without producing simple sound or rhythm and reproduce melodylike tones".
There are three musical strips in central and northern Japan-one of which plays the tune of a
Japanese pop song. Reports say the system was invented by Shizuo Shinoda. He scraped some
markings into a road with a bulldozer(推土机)before driving over them and found that they helped to
produce all kinds of tones.
The optimal speed for melody road is 44 kph, but people say it is not always easy to get the
intended sound.
"You need to keep the car windows closed to hear well," wrote one Japanese blogger. "Driving too
fast will sound like playing fast forward, while driving around 12 mph[20 km/h]has a slowmotion effect,
making you almost carsick."
B. grooves
C. spaces between intervals
D. bulldozers
B. how big the grooves are
C. the number of the grooves
D. the speed of the car
B. possible
C. best
D. suitable
B. drive slowly
C. open the windows wide
D. keep the windows closed
B. Melody Roads in Japan
C. A Musical Road Surface
D. A New Invention in Japan

age you ought to be growing away from your parents. You should be learning to stand on your own two
feet. But take a good look at the present rebellion. It seems that teenagers are taking the same way of
showing that they disagree with their parents. Instead of striking out boldly on their own, most of them
are clutching (紧握) at one another"s hands for reassurance.
They claim they want to dress as they please. But they all wear the same clothes. They set off in new
directions in music. But somehow they all end up huddled (聚在一起) round listening to the same record. Their reason for thinking or acting in thusandsuch a way is that the crowd is doing it. They have come out
of their cocoon (蚕茧) into a larger_cocoon.
It has become harder and harder for a teenager to stand up against the popularity wave and to go his
or her own way. Industry has firmly carved out a teenage market. These days every teenager can learn
from the advertisements what a teenager should have and be. And many of today"s parents have come to
award high marks for the popularity of their children. All this adds up to a great barrier for the teenager
who wants to find his or her own path.
But the barrier is worth climbing over. The path is worth following. You may want to listen to
classical music instead of going to a party. You may want to collect rocks when everyone else is
collecting records. You may have some thoughts that you don"t care to share at once with your
classmates. Well, go to it. Find yourself. Be yourself. Popularity will come-with the people who respect
you for who you are. That is the only kind of popularity that really counts.

A. Convincing.
B. Instructive.
