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 （紅外線）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 （殺蟲劑）spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest （害蟲）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.
【小題1】 Plants will emit an increased amount of heat when they are______________.

A．sprayed with pesticides
B．facing an infrared scanner
C．in poor physical condition
D．exposed to excessive sun rays
【小題2】．In order to apply pesticide spraying precisely, we can use infrared scanning to____________.

_______________.
A．the lack of official support
B．its high cost
C．the lack of financial support
D．its failure to help increase production
【小題5】 Infrared scanning technology may be brought back into operation because of_____________.

A good modern newspaper is an extraordinary piece of reading. It is unusual for what it contains: the news from local crime to international politics, from sports to business to fashion to science, and the comments and special features(特寫)as well, from editorial page to feature articles, from interviews to criticism of books, art, theatre, and music. A newspaper is even more unusual for the way one reads it never completely, never straight through, but always by jumping from here to there, in and out, glancing at one piece, reading another article all the way through, reading just a few paragraphs of the next.
A good modern newspaper offers a variety to attract many different readers, but far more than any one reader is interested in. What brings this variety together in one place is its topicality, that is, its immediate relation to what is happening in your world and your locality now. But this immediacy and the speed of production that goes with it also mean that much of what appears in a newspaper has no more than temporary value. For all these reasons, no two people really read the same paper: what each person does is to put together, out of the pages of that day’s paper, his own selection and order, his own newspaper. For all these reasons, reading newspapers efficiently which means getting what you want from them without missing things you need but without wasting time, demands skill and self-awareness(意識(shí)) as you change and apply the techniques of reading.
【小題1】What does the underlined word in the second paragraph mean ?

A．wide coverageB．speed in reporting news
C．various style　　D．popularity among readers
【小題2】According to the passage, the reason why no two people really read the same newspaper is that ___________.
A．people are interested in the same kind of news
B．different people prefer different newspapers
C．people scan for the news they are interested in
D．people have different views about what a good newspaper is
【小題3】A good newspaper offers “a variety” to readers because ___________.
A．readers like to read different newspapers
B．it has to cover things that happen in a certain locality
C．readers are difficult to please
D．it tries to serve different readers
【小題4】The best title for this passage would be ___________.
A．The Characteristics of a Good Newspaper
B．The Importance of a good Newspaper
C．Good Newspapers and Bad Newspapers
D．Some Advice on How to Read a Newspaper

What will power your house in the future？Nuclear，wind，or solar power？According to scientists at the Massachusetts Institute of Technology (MIT) in the US，it might be leaves — but artificial (人造的) ones.
Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用)．Now researchers have found a way to imitate this seemingly simple process.
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts (催化劑)．Similar to natural leaves，it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell，which uses those two materials to produce electricity，located either on top of a house or beside the house.
Though the leaf is only about the shape of a poker card，scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. “One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology,” said Nocera at a conference of the American Chemical Society.
The artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf，by contrast，is made of cheap materials，easy to use and highly stable. In laboratory studies，Nocera showed that an artificial leaf prototype (原型) could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera's recent discovery of several powerful，new and inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now，the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides，the device can run in whatever water is available；that is，it doesn't need pure water. This is important for some countries that don't have access to pure water.
With the goal to “make each home its own power station” and “give energy to the poor”，scientists believe that the new technology could be widely used in developing countries，especially in India and rural China.
【小題1】Which of the following orders correctly shows how the artificial leaf is used to produce electricity?
a．a(chǎn)rtificial leaves split water into hydrogen and oxygen
b．the hydrogen and oxygen gases are stored in a fuel cell
c．the artificial leaves are put in water
d．the fuel cell uses hydrogen and oxygen to produce electricity

A．c，a，b，d B．c，b，a，d
C．b，c，a，dD．c，a，d，b
【小題2】The purpose of the scientists at MIT in developing the new artificial leaf is to________.
A．build up more power stations in the world
B．provide cheaper energy for developing countries
C．offer people in developing countries access to pure water
D．gain a deeper understanding of the photosynthesis process
【小題3】The main idea of this passage is ________.
A．a(chǎn)n introduction to the history of artificial leaves
B．a(chǎn) mixture of water power and solar energy
C．giving energy to the poor
D．a(chǎn)n invention copying photosynthesis

Boiler rooms are often dirty and steamy, but this one is clean and cool. Fox Point is a very new47-unit living building in South Bronx, one of the city’s poorest areas. Two-thirds of the people living there are formerly (以前) homeless people, whose rent is paid by the government. The rest are low-income families.  The boiler room has special equipment, which produces energy for electricity and heat. It reuses heat that would otherwise be lost to the air, reducing carbon emissions(碳排放)while also cutting costs.
Fox Point is operated by Palladian, a group that specializes in providing housing and services to needy, people. Palladian received support from Enterprise Community Partners (ECP), which helps build affordable housing by providing support to housing developers.
ECP has created national standards for healthy, environmentally (環(huán)境方面) clever and affordable homes which are called, the Green Communities Standards. These standards include water keeping, energy saving and the use of environmentally friendly building materials.  Meeting the standards increases housing construction costs by 2%, which is rapidly paid back by lower running costs. Even the positioning of a window to get most daylight can help save energy.
Michael. Bloomberg, New York's mayor, plans to create 165,000 affordable housing units for500,000 New Yorkers. Almost 80% of New York City’s greenhouse-gas emissions come from buildings, and 40% of those are caused, by housing. So he recently announced that the city’s Department of Housing and Preservation and Development (DHPD) , whose duty is to develop and keep the city’s supply of affordable housing, will require all its new projects to follow ECP’s green standards.
Similar measures have been taken by other cities such as Cleveland and Denver, but New York’s DHPD is the largest city developer of affordable housing in the country.
【小題1】 What is the purpose of describing the boiler room in the first paragraph?

A．To explain the measures the city takes to care for poor people.
B．To suggest that affordable housing is possible in all areas.
C．To show how the environment-friendly building works.
D．To compare old and new boiler rooms.
【小題2】 What is an advantage of the buildings meeting the Green Communities Standards?
A．Lower running costs.
B．Costing less in construction.
C．Less air to be lost in hot days.
D．Better prices for homeless people.
【小題3】 It can be learned from the text that,
A．New York City is seriously polluted
B．people’s daily life causes many carbon emissions in New York City
C．a(chǎn) great number of people in New York City don't have houses to live in
D．some other cities have developed more affordable housing than New York City
【小題4】 What is the main purpose of this text?
A．To call on people to pay more attention to housing problems.
B．To prove that some standards are needed for affordable housing.
C．To ask society to help homeless people and low-income families.
D．To introduce healthy, environmentally clever-and affordable housing.

Disposing(處理)of waste has been a problem since humans started producing it.As more and more people choose to live close together in cities,the waste-disposal problem becomes Increasingly difficult.
During the eighteenth century,it was usual for several neighboring towns to get together to select a faraway spot as a dump site.Residents or trash haulers(垃圾拖運(yùn)者)would transport household rubbish,rotted wood,and old possessions to the site.Periodically(定期的)some of the trash was burned and the rest was buried.The unpleasant sights and smells caused no problem because nobody lived close by.
Factories,mills,and other industrial sites also had waste to be disposed of.Those located on rivers often just dumped the unwanted remains into the water.Others built huge burners with chimneys to deal with the problem.
Several facts make these choices unacceptable to modern society.The first problem is space Dumps,which are now called landfills,are most needed in heavily populated areas.Such areas rarely have empty land suitable for this purpose.Property is either too expensive or too close to residential(住宅區(qū)的) neighborhoods.Long-distance trash hauling has been a common practice but once farm areas are refusing to accept rubbish from elsewhere,cheap land within trucking distance of major city areas is almost nonexistent.
Awareness(意識(shí)) of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers,ground water,land and air is a price people can no longer pay to get rid of waste. The amount of waste,however,continues to grow.
Recycling efforts have become commonplace,and many towns require their people to take part.Even he most efficient recycling programs,however,can hope to deal with only about 50 Percent of a city’s reusable waste.
【小題1】The most suitable title for this passage would be _______.

A．Places for Disposing Waste B．Waste Pollution Dangers
C．Ways of Getting Rid of Waste D．Waste Disposal Problem
【小題2】During the 18th century,people disposed their waste in many ways EXCEPT for _______.
A．burying it B．recycling it
C．burning it D．throwing it into rivers
【小題3】What can be inferred from the fourth paragraph?
A．Farm areas accept waste from the city in modern society.
B．There is cheap land to bury waste in modern society.
C．It is difficult to find space to bury waste in modern society.
D．Ways to deal with waste in modern society stay the same.
【小題4】The main purpose of writing this article is to _______.
A．draw people’s attention to waste management

Global warming is when the earth heats up，the temperature rises.It happens when greenhouse gases—carbon dioxide，water vapor，nitrous oxide(二氧化氮)，and methane(沼氣) trap heat and light from the sun in the earth’s atmosphere，which increases the temperature.This is like when heat is trapped in a car.On a very hot day，the car gets hotter when it is out in the parking lot.This is because the heat and light from the sun can get into the car，by going through the windows，but it can’t get back out.Once the light is inside the car，it is trapped and the heat builds up，just like it does in the earth’s atmosphere.This is what the greenhouse effect does to the earth.The heat and light can get through the atmosphere，but it can’t get out.As a result，the temperature rises.
Sometimes the temperature can change in a way that helps us.The greenhouse effect makes the earth appropriate for people to live on.Without it，the earth would be freezing，or on the other hand it would be burning hot.We would not get the sun’s heat and light to make the night somewhat warm.During the day，especially during the summer，it would be burning because the sun would be up with no atmosphere to filter(過濾) it，so people，plants，and animals would be exposed to all the light and heat.
Although the greenhouse effect makes the earth able to have people living on it，if there gets to be too many gases，the earth can get unusually warmer，and many plants，animals，and people will die.They would die because there would be less food (plants like corn，wheat，and other vegetables and fruits)．This would happen because the plants would not be able to take in the heat.This would cause us to have less food to eat，but it would also limit the food that animals have.Gradually，people，plants，and animals would all die of hunger.
People are doing many things to try to stop global warming.One thing people are doing is carpooling.Carpooling is driving with someone to a place that you are both going to.This minimizes the amount of greenhouse gases put into the air by a car.
Another thing that people are doing is being more careful about leaving things turned on like the television，computer，and the lights.A lot of people are taking time away from the television，and instead，they are spending more time outdoors.This helps our planet out a lot.Now，more people are even riding buses，walking to school，and riding their bikes to lower the amount of greenhouse gases in the air.
Planting trees and recycling also help.If you recycle，less trash goes to the dump，and less trash gets burned.As a result，there are fewer greenhouse gases in our atmosphere.Although adults do many things to help stop global warming，kids can do just as much.
【小題1】By the example given in Paragraph 1，the author wants to ________.

A．explain how greenhouse gases work 
B．show his feeling in a car in hot summer 
C．tell us cars are causes of greenhouse gases 
D．say that there are greenhouse gases in every car 
【小題2】The underlined word “it” in Paragraph 2 refers to “________”．
A．light B．heat 
C．temperature D．greenhouse effect 
【小題3】What is the main idea of Paragraph 3?
A．If there is greenhouse effect，all the plants will die. 
B．Human beings are likely to disappear from the earth. 
C．Crops can’t take the heat if there is greenhouse effect. 
D．Although greenhouse effect is necessary，too much of it causes us to die. 
【小題4】What will the author most probably discuss in the paragraph that follows?
A．Why cars and buses pollute the air a lot. 
B．What kids can do to help stop global warming. 
C．What global warming is doing to the environment. 
D．Who should be responsible for the environmental problems.

Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world? It is an increasingly urgent question, given the recent mining accidents in Sago, W. Va and Huntington, Utah. A small group of engineers and robotics experts look forward to a day in the not-too-distant future when robots and other technology do most of the dangerous mining work. 
Robotic technology, in particular, holds much promise, McAteer says, especially when it comes to mapping mines and rescuing trapped miners --- the special operations of the mining industry.
One of the first mining robots was developed five years ago at Carnegie Mellon University’s Robotics Institute. It was called Groundhog. It used lasers(激光器) to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business. 
The latest design is called Cave Crawler. It’s a bit smaller than Groundhog，and even more advanced. It can take photos and videos and has more sensors that can detect the presence of dangerous gases. Incredibly，the robot has a real sense of logic. If it comes across an obstacle it gets momentarily confused. It has to think about what to do and where to go next. Sometimes it throws a fit just like a real person. 
The greatest problem, though, is cost. The money of the earliest research project was provided by the government, but that money had dried up, and it’s not clear where future money will come from. Partly for that reason, and partly because of advances in safety, mining is not nearly as dangerous as it was in the past. Since 1990, fatalities(致命性) have declined by 67% and injuries by 51% , according to the National Mining Association.
Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry. The robots do the most boring and dangerous jobs，but won’t get rid of the need for human workers.
【小題1】The latest robot is more advanced than Groundhog, mainly because ____.

A．it can map abandoned mines
B．it can see in the dark tunnels
C．it’s smaller than Groundhog
D．it has a real sense of logic
【小題2】The underlined phrase “throws a fit” in paragraph 4 probably means“______”
A．gets angry B．gets sick
C．becomes hungry D．becomes cheerful
【小題3】We can infer from the last paragraph that _____ .
A．robots in mines will serve much in the automotive industry
B．there will be no need for human workers in mines
C．the mine robots will have a very bright future
D．robots in mines only do some simple jobs now
【小題4】We can infer from the text that ______.
A．the mining robots do most of the mining work at present
B．groundhog can discover the presence of dangerous gases
C．experts are trying to make robots help miners with dangerous work
D．robots cannot do dangerous work in dark areas
【小題5】What can be the best title for the text?
A．Mining Accidents in America
B．Robots in Mines
C．Cave crawler, the Latest Robot
D．The Future of Robots

Move Earth—It’s Not Science Fiction

LONDON—Scientists have found an unusual way to  prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets(彗星)in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.
This idea for improving our climate comes from a group of US National Aeronautics and Space Administration(NASA)engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.
The plan put forward by Dr. Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun, ”Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The Sun is certain to heat up in about a billion years and so“seriously compromise” our biosphere(生物圈)—by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation(誤算)in orbit could fire it straight at Earth—with deadly consequences.
There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position, it is“most likely the Moon would be stripped away from Earth”. This would greatly change our planet’s climate.
【小題1】What makes the scientists plan to move Earth?

A．A few comets are moving to the direction of Earth.
B．Earth’s working life is coming to an end soon.
C．Earth will become too hot for mankind to keep alive.
D．The moon is moving farther and farther away from Earth.
【小題2】If the plan is successful, Earth will have a working life of　　　years.
A．12 billion　B．6 billion
C．18 billion　D．24 billion
【小題3】What serious problems might the plan cause according to the passage?
A．The comet might hit Earth and man might lose the Moon.
B．Earth might be moved too far away and man might be frozen to death.
C．The comet might hit Jupiter or Saturn and never return to Earth.
D．Earth’s working life might be greatly shortened.
【小題4】What does the underlined word“compromise”mean?
A．Provide. B．Benefit.
C．Share. D．Endanger.
