    Against the assumption that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.

    This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.

    This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.

    Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone(臭氧)levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.

    “We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.

(1)、According to the new findings, taking steps to prevent northern forest fires may _______.

A、result in a warming climate B、cause the forest fires to occur more frequently C、lead to a longer fire season D、protect the forests and the environment there
(2)、Earlier studies about northern forest fires ________.

A、analyze all aspects of how northern fires influence climate B、indicate that forest fires will pollute the atmosphere C、suggest that people should take measures to protect environment D、suggest that the fires will speed up climate warming
(3)、The underlined phrase “soaked up” in the last paragraph most probably means ________.

A、released B、absorbed C、created D、disturbed
(4)、From the text we can draw a conclusion that forest fires in Alaska, Canada and Siberia may ______.

A、warm the climate as the assumption goes B、allow more snow to reflect more sunlight into space and thus cool the climate C、destroy large areas of forests and pollute the far-off sea ice D、help to gain more energy rather than release more energy

    If you have a chance to go to Finland, you will probably be surprised to find how “foolish” the Finnish people are.

    Take the taxi drivers for example. Taxis in Finland are mostly high-class Benz with a fare of two US dollars a kilometer. You can go anywhere in one, tell the driver to drop you at any place, say that you have some business to attend to, and then walk off without paying your fare. The driver would not show the least sign of anxiety.

    The dining rooms in all big hotels not only serve their guests, but also serve outside diners. Hotel guests have their meals free, so they naturally go to the free dining rooms to have their meals. The most they would do to show their good faith is to wave their registration card to the waiter. With such a loose check, you can easily use any old registration card to take a couple of friends to dine free of charge.

    The Finnish workers are paid by the hour. They are very much on their own as soon as they have agreed with the boss on the rate(价钱). From then on, they just say how many hours they have worked and they will be paid accordingly(相应地).

    With so many loopholes(漏洞) in everyday life, surely Finland must be a heaven to those who love to take “petty advantages”. But the strange thing is, all the taxi passengers would always come back to pay their fare after they have attended to their business; not a single outsider has ever been found in the free hotel dining rooms. And workers always give an honest account of the exact hours they put in. As the Finns always act on good faith in everything they do, living in such a society has turned everyone into a real “gentleman”.

    In a society of such high moral practice, what need is there for people to be on guard against others?

    The arm bones of women who lived 7-000 years ago show a surprising level of strength-even higher than today's professional athletes. That's according to a first-ever study comparing prehistoric(史前的)bones to those of living people. The finding suggests a revision of history — the everyday lives of prehistoric women were filled with hard labor, rather than just sitting at home doing lighter tasks while the men struggled and fought for life.

    “Before the study, there are no clear records describing how our ancient ancestors lived. It can be easy to forget that bone is a living tissue, one that responds to the difficulties we put our bodies through,” said lead author Alison Macintosh. “Physical force and muscle activity both put pressure on the bone. The bone reacts by changing in shape, thickness and other aspects over time. ”

    Previous studies only compared female bones to contemporary male bones, the researchers said — and that's a problem, because the response of male bones to stress and change is much bigger than that of women. For instance, as humans moved from a hunter-gatherer lifestyle constantly on the move to a more settled agrarian (农耕的)one, changes can be observed in the structure of the shinbone (胫骨) — and these changes were much more evident in men.

    However, a comparison of the bones of prehistoric women to the bonos of living female athletes can help us work out a more accurate picture of what those prehistoric women were doing. “By analyzing the bones of living people and comparing them to the ancient hones, we can start to explain the kinds of labor our ancestors were performing,” Macintosh said. What they found was that women's leg strength hasn't changed a great deal, but their arms used to be very powerful. Prehistoric women, the researchers found, had arm strength 11〜16 percent stronger than those of modern rowers, and 30 percent stronger than those of non-athletes.

A great poem makes you want to get out of your chair and pace around the room. {#blank#}1{#/blank#}. But if you haven't developed your. poetry taste in a while, that feeling might be a little hard to tap into. Here are four tips that can help you get there.

Read aloud and out loud

When reading a poem, it is important to remember that it is not just words on a page, but is meant to be heard or read aloud. {#blank#}2{#/blank#}. It will enhance the appreciation of the piece.

{#blank#}3{#/blank#}.

Approaching poetry with a perspective of finding connections between the poem and one's own life can be a valuable tool for appreciating the poem more. Connecting to the emotions, memories and even the same life experiences can help to relate more to the poem and in turn, truly appreciate it. Through this connection to the poem, we can better understand the feelings, actions and words of the poem.

Create a dialogue

More often than not, a lot of hidden or "unsaid" messages are delivered in poetry. {#blank#}4{#/blank#}. A fruitful discussion about a poem can help readers to understand the poem more, through their different interpretations and opinions.

Write your own poem

{#blank#}5{#/blank#}. As you write your own poem, think about the structure you want to create, the literary devices you want to employ and the emotion you want to arouse. As you write your own poem, you will see your appreciation of the original poem rise, as you gain a sense of the effort that goes into crafting a poem. In this way, it can become much easier to appreciate the poem being read.

A. Find connections

B. Pair poetry with other art forms

C. Writing can be a great way to start your appreciation of a poem

D. It makes you want to throw your hands up and show it to somebody

E. Reading the poem aloud helps you understand the emotion of the poet fully

F. Having a discussion around a poem allows readers to bring out these messages

G. Possessing a critical eye allows readers to appreciate the art of poetry in a meaningful way
