The amount of carbon taken in by growing plants increased from 1982 through 1999 as
temperatures rose and the amount of carbon dioxide in the atmosphere increased. But a new study
in Friday ’ s edition of the journal Science found a drought - related decline in such plant growth
from 2000 to 2009，even though temperatures continued to climb.
As drought caused by warming reduces the land ’ s ability to take in carbon，the result could
be more carbon dioxide left in the atmosphere，and thus more warming，Zhao Maosheng from the
University of Montana explained in a telephone interview.
“This is a pretty serious warning that warmer temperatures are not going to endlessly improve
plant growth ’” co - author Steven Running，also from the University of Montana ’ said in a
statement. “ We see this as a bit of a surprise，and potentially significant on a policy level because
previous interpretations suggested global warming might actually help plant growth around the
world, “ he said.
Instead, he and Zhao found a small but measurable decline of about 1%，compared to a6%
increase in the past decade.
Their study，based on the data collected by NASA satellites，found that north areas continued
to increase plant growth，thanks to warmer temperatures and a longer growing season.
Someone commented, "This past decade’ s net decline in earthly productivity suggests that a
complex relationship between temperature, rainfall, cloudiness, and carbon dioxide, probably in
combination with other factors such as nutrients(營(yíng)養(yǎng)）and land management，will determine
future patterns and trends in productivity.，，
【小題1】From the first paragraph, we can learnin the recent decade or so.

A．the emission(排放)of carbon hasn’ t been reduced
B．draught has been causing loss of soil and water
C．carbon dioxide levels have been rising
D．the rise of temperature doesn' t promote the plant growth
【小題2】Zhao Maosheng really worried that .
E.     more and more land will be abandoned
F.    the climate becomes warmer and warmer
G.   the emission of carbon dioxide increases
H.   draught further reduces the number of the plants
【小題3】Steven Running made his statement to  .
I.      confirm Zhao' s views on the influence of temperature rise
J.     urge the government to take necessary measures
K.    warn the people to strengthen the plant protection
L.    support Zhao* s views on lhe plant production
【小題4】We can infer from the passage that  .
A．global warming will determine the future productivity
B．various factors play a key role jointly on future productivity
C．earthly productivity actually increased in the past decade
D．temperature rise has had no effect on future producticity patterns

You can be proud of yourselves, even if you can only make one or two of these green changes. The goal here is to limit carbon dioxide and other greenhouse gases, which are closely associated to the big problem of global-warming.

Strategy 1:  Bring your own cup to Starbucks

You'll get a 10-cent discount, and it's one less paper cup to end up in a dustbin

The store won't create more waste when they throw away a cup

Strategy 2: Turn off your computer

When in standby mode, your PC is still using energy

Turning off a monitor for 40 hours a week may only save $ 5 a month, but it reduces CO2 by 750 pounds

Strategy 3:  Reuse plastic bags

Instead of throwing away 100 billion plastic bags a year, try and get a second, third, or tenth use out of them. Better yet, next time you shop, try a reusable bag

You're reducing pollution. The amount of oil it would take to make just 14 plastic bags would run your car for one mile

Strategy 4: Use recycled paper in the bathroom

Most of the toilet paper we use is made from  trees found in forests previously untouched by humans

If every household replaced one roll of toilet paper with a recycled one,424,000trees would still be standing. Look for eco paper towels too

Strategy 5: Buy energy-efficient appliances(電器)

Replace the old fridge with an Energy Star appliance and you'll use 15 percent less energy. It might be a little expensive to buy, but  you'll save money on your electricity bills and help the environment

If we all used one Energy Star appliance at home, it would be like planting 1.7 million acres of new trees

Strategy 6: Plant a tree

Adding green to your garden is beautiful and earth-pleasing

Just one tree will help make cleaner air and save the environment from 5, 000 pounds of hot carbon dioxide each year

1.What is the best title for the passage?

A．Strategies to Save Money

B．Ways to be Earth-Friendly

C．Strategies to End Global-Warming

D．Ways to Limit Carbon Dioxide

2.According to the writer, what will happen if our PC is switched off when not in use?

A．It will help to save a large amount of money.

B．It will help to reduce a great deal of CO2.

C．It will save the amount of oil that runs your car for a mile.

D．It will be like planting 1.7 million acres of new trees.

3.Which strategies suggest recycling or reuse of things?

A．Strategies 1 & 3.

B．Strategies 2 & 5.

C．Strategies 3 & 6.

D．Strategies 4 & 5.

4.What benefits do these strategies have in common?

A．They all help reduce the use of energy like electricity.

B．They all cut down the amount of the use of paper.

C．They all result in producing less greenhouse gases.

D．They all aid to preserve our trees and forest.

科目：高中英語(yǔ) 來(lái)源：2014屆四川省成都市高一5月月考英語(yǔ)試卷（解析版） 題型：閱讀理解

Taiwan police cannot decide whether to treat it as an extremely act of stealing or an even cheat. Either way, it could be the perfect crime, because the criminals are birds—homing pigeons !

The crime begins with a telephone message to the owner of a stolen car: if you want the car back, pay up. Then, the car owner is directed to a park, told where to find a bird cage and how to attach money to the neck of the pigeon inside. Carrying the money in a tiny bag, the pigeon flies off.

There have been at least four such pigeon pick-ups in Changwa. What at first seemed like the work of a clever stay-at-home car thief, however,  may in fact be the work of an even lazier and more inventive criminal mind—one that avoids not only collecting money but also going out to steal the car in the first place. Police officer Chen says that the criminal probably has pulled a double trick: he gets money for things he cannot possibly return. Instead of stealing cars, he lets someone else do it and then waits for the car-owner to place an advertisement in the newspaper asking for help.

The thought is supported by the fact that, so far, none of the stolen cars have been returned. Also, the amount of money demanded-under 3,000 Taiwanese dollars–seems too little for a car worth many times more.

Demands for pigeon-delivered money stopped as soon as the press reported the story. And even if they start again, Chen holds little hope of catching the criminal. “We have more important things to do,” he said.

1.After the car owner received a phone call, he _______.

A．went to a certain pigeon and put some money in the bag it carried

B．gave the money to the thief and had his car back in a park

C．sent some money to the thief by mail

D．told the press about it

2.The “l(fā)azier and more inventive” criminal refers to _______.

A．the car thief who stays at home

B．one of those who put the ads in the paper

C．one of the policemen in Changwa

D．the owner of the pigeons

3.The writer mentions the fact that “none of the stolen cars have been returned” to show _______.

A．how easily people get fooled by criminals

B．what Chen thinks might be correct

C．the thief is extremely clever

D．the money paid is too little

4.The underlined word “they” in the last paragraph refers to ____.

A．criminals

B．pigeons

C．the stolen cars

D．demands for money

5. We may infer from the text that the criminal knows how to reach the car owners because _______.

A．he reads the ads in the newspaper

B．he lives in the same neighborhood

C．he has seen the car owners in the park

D．he has trained the pigeons to follow them

 “You can learn English more efficiently if you spend 20 minutes a day for a week than if you spend two hours a day.” This is what a teacher usually 71  when he tells his students how to allot(分配)their time. But is it true?

Suppose you have a bucket with a small hole in its bottom. Now you are asked to fill the bucket with the water in a basin. If you are too little a boy to lift the basin full of water, you are sure 72   a bowl or something alike. You will dip out the water from the basin with the bowl and pour it into the bucket .You may dip from the basin again and again. However, you will soon find that as soon as you pour a bowl of water into the bucket , most of the water 73  through the hole , so you are 74   able to fill up the bucket this way.

On the contrary , if you are an adult, you will 75   lift the basin and pour the whole basin of water into the bucket at once. Now, the bucket is full. Though the water in it is also leaking out, you at least have filled up the bucket with water. If you want to 76   the bucket full, you only have to add a bowl of water now and then .

The same is true of English learning. Let us 77  a simple example. If you learn 10 new words today, you are most likely to remember 9 tomorrow. But if you try to learn 30 words today, though you may forget far more than one word , you may 78  be able to remember 11 or 12 words tomorrow.

Day in and day out , you will be able to remember a large number of words, 79  you may forget some of them.

 80  , the more time you spend at a time, the more you will learn on the whole. Of course, the amount of time you spend each time must be within the limit that you do not exhaust (使筋疲力盡)yourself .

科目：高中英語(yǔ) 來(lái)源：江蘇省2010屆高三考前適應(yīng)性考試英語(yǔ)試題 題型：閱讀理解

 

One of the most difficult questions to answer is how much a job is worth. We naturally expect that a doctor’s salary will be higher than a bus conductor’s wage. But the question becomes much more difficult to answer when we compare, say, a miner with an engineer, or an unskilled man working on an oil-rig(鉆油機(jī)) in the North Sea with a teacher in a secondary school. What the doctor, the engineer and teacher have is many years of training in order to obtain the necessary qualifications for their professions. We feel instinctively that these skills and these years, when they were studying instead of earning money, should be rewarded. At the same time we recognize that the work of the miner and the oil-rig laborer is both hard and dangerous, and that they must be highly paid for the risks they take.

Another factor we must take into consideration is how socially useful a man’s work is, regardless of the talents he may bring to it. Most people would agree that looking after the sick or teaching children is more important than, say, selling secondhand cars or improving the taste of toothpaste by adding a red stripe to it. Yet it is almost certain that the used car salesman earns more than the nurse, and that research chemist earns more than the school teacher.

Indeed, this whole question of just rewards can be turned on its head. You can argue that a man who does a job which brings him personal satisfaction is already receiving part of his reward in the form of a so-called “psychic(精神的) wage”, and that it is the man with the boring, repetitive job who needs more money to make up for the soul-destroying monotony(單調(diào)) of his work. It is significant that that those jobs which are traditionally regarded as “vocations” --- nursing, teaching and the Church, for example --- continue to be poorly paid, while others, such as those in the world of sport or entertainment, carry financial rewards out of all proportion to their social worth.

Although the amount of money that people earn is in reality largely determined by market forces, this should not prevent us from seeking some way to decide what is the right pay for the job. A starting point for such an investigation would be to try to decide the ratio which ought to exist between the highest and the lowest paid. The picture is made more complicate by two factors: firstly by the “social wage”, i.e, the welfare benefits which every citizen receives; and secondly, by the taxation system, which is often used as an instrument of social justice by taxing high incomes at a very high rate indeed. Allowing for these two things, most countries now regard a ratio of 7:1 as socially acceptable. If it is less, the highly-qualified people carrying heavy responsibilities become disillusioned, and might even end up by emigration(移民) (the so-called “brain-drain” is an evidence that this can happen). If it is more, the gap between rich and poor will be so great that it will lead social tensions and ultimately to violence.

1. The professional man, such as the doctor, should be well paid because ______.

A. he has spent several years learning how to do his job

B. his work involves much great intelligence than, say, a bus conductor’s

C. he has to work much harder than most other people

D. he knows more than other people about his subject

2. The “brain-drain” is an evidence that ______.

A. well-educated people are prepared to emigrate whenever they can get a better paid job

B. people with jobs or responsibility expect to be highly paid

C. high taxation is a useful and effective instrument of social justice

D. the poor are generally more patriotic(愛國(guó)的) than the rich

3. As far as rewarding people for their work is concerned, the writer, believes that ______.

A. we should pay for socially-useful work, regardless of the person’s talent

B. we should pay people according to their talents

C. market forces will determine how much a person is paid

D. qualified people should be the highest paid

4. The argument of the “psychic wage” is used to explain why ______.

A. people who do socially important work are not always well paid

B. people who do monotonous jobs are highly paid

C. you should not try to compare the pay of different professions

D. some professional people are paid more than others
