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.
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
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
The underlined phrase “soaked up” in the last paragraph most probably means ________.
A. released B. absorbed C. created D. disturbed
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 .

[1]All people have dreams and they obey the rule that if you can dream it, you can achieve it! Here are four goals for people to reach a perfect life in their future.
[2]The first goal common to all of us in health and energy. We all want to be healthy and fit, to have high levels of energy and to live free of pain and illness. Today, with the incredible advances in medical science, the quality of our health and fitness, and our lifespan, is largely determined by design, not by chance. People with excellent health habits are far healthier, have more energy, and live longer and better than people who have poor health habits. Remember that health is not everything, but without health everything is nothing!
[3]The second goal that we all have in common is to enjoy excellent relationships – intimate, personal or social – with the people we like and respect, and who is turn. Fully 85% of your happiness will be determined by the quality of your relationships at each stage, and in each area, of your life. How well you get along with people, and how much they , have more impact on the quality of your life than perhaps any other factor.
The third common goal is to do work that we enjoy, to do it well, and to be well paid for it. You want to be able to get and keep the job you want, to get paid more and promoted (晉升) faster. You want to earn the very most that is possible for you at each stage of your career, whatever you do.
The fourth goal we all have in common is to achieve financial independence. You want to reach the point in life where you have enough money so that you never have any financial worries. You want to be completely free of them. You want to be able to order dinner in a restaurant without referring to the price listing to determine what you want to eat.
1.What does this passage chiefly talk about? (no more than 12 words)
2.Fill in the blank in Paragraph 3 with proper words. (no more than 6 words)
3.Complete the following sentence with proper words according to the underlined sentence in Paragraph 4? (no more than 6 words)
Everybody wants to make no matter what job he is engaged in.

A recent Auburn University study provides some real numbers to back a theory we’ve all known was true for some time—planting a shade tree near your home reduces energy bills significantly in the spring and summer months. The study, conducted in Auburn,
Alabama, included 160 homes with different levels of shade. Each home’s energy usage was monitored and compared to other houses with similar energy— using patterns, size, type of cooling system, etc. Here are some highlights from the study:
Houses with trees on the west side of their home had a “much lower power bill”.
Older homes had the most shade coverage, because people did not use to rely on air conditioning as much to keep them cool.
Children under age 12 consume the most power in a home as they watch television, play games and frequently leave lights on.
Fall and early winter are the perfect seasons to plant a tree. This time of year many nurseries(苗圃)are trying to reduce their inventory of trees heading into the winter, so you may find a deal on trees easily to plant around your lot.
While you have the spade out, consider planting a tree near your outside air conditioning unit. The shade will keep the unit cooler and help it operate more efficiently. Be sure to plant far enough from the unit to allow proper airflow, and account for the tree’s growth over time.
It actually hurts to watch the trees being knocked over when land developers plan neighborhoods because trees could provide much needed shade to new homeowners, reducing their electric bill and the amount of energy they consume. Hopefully this study, and more like it in the future, will encourage developers and builders to plan around trees as much as possible to offer homeowners a shaded lot.
1.What does the passage mainly tell us?
A.A new study about planting trees.
B.Planting trees to reduce your power bill.
C.Houses with trees on the west side.
D.Don't cut trees down when planning neighborhoods.
2.The underlined word "inventory" in Paragraph 5 is closest in meaning to ________.
A.invention B.volume C.list D.type
3.According to the passage, ____ might spend more energy cost.
A.houses with trees on the west side of their home
B.older houses with the most shade coverage
C.houses with different levels of shade
D.houses with the children under age 12
4.Which is NOT the benefit of planting a tree near the outside air conditioning unit?
A.The shade will keep the unit much cooler.
B.The shade helps the unit operate more efficiently.
C.The trees stops the unit having proper airflow.
D.The shade prevents the sunlight from shining on the unit.
5.What can we learn from this study?
A.The study is carried out by the students at Auburn University, Alabama.
B.While planning new neighborhoods, developers often cut down the trees there.
C.Houses with trees on the east side of their house had a lower power bill.
D.The study will prevent developers and builders from planning more trees.

ANCHORAGE, Alaska--The 2004 winner of Alaska’s famous 1,000-mile sled-dog race, the Iditarod, won again at age 53 to become the oldest champion in 2013, a year after his son became the youngest winner.
Mitch Seavey got his dogs to the finishing line first in 9 days, 7 hours, 39 minutes and 56 seconds. His son, Dallas Seavey, now 26, ended up ranking fourth, behind the older competitor, 43-year-old Aliy Zirkle, who followed four-time champion Jeff King, now 57.
Mitch Seavey, who lives in Seward, Alaska, operates a seasonal sled-dog touring business. The race was Mitch Seavey’s 20th Iditarod.
This year’s contest was marked by unusual conditions and unseasonable rain in the northern part of the trail, and conditions that Seavey said helped his team. “It seems like the tougher it is, the better we can do.”
He also thought highly of Zirkle, a New England immigrant(移民)who now lives in Two Rivers, Alaska. “She’s a great musher(趕狗拉雪橇的人), and she’s going to win the Iditarod sometime, and probably more than once. We just had a little more energy, I think.” Zirkle, one of the most popular mushers, was greeted by shouts of “Aliy, Ally” from the fans as she drove her dog team approaching the finishing line on Nome’s Front Street. “I am pretty happy to be here,” she said. “I was going for it.”
The Iditarod Trail Sled Dog Race is one of the few major U. S. sports events in which men and women compete on an equal footing. The name “Iditarod” dates from a local Athabascan term meaning “a far, distant place”. Youthful mushers in the race may have some physical advantages--they can do some things more easily. But more importantly, winning the race needs the experience in dog race.
The year’s event started on Saturday, March 2 with a ceremonial nm in Anchorage. Of the 66 mushers who started the race, 10 had dropped out of competition as of Tuesday night. For his victory, Mitch Seavey will take home $50,400 and a new truck.
1.Which of the following is true according to the passage?
A. Mitch Seavey is the oldest competitor in the sled-dog race in 2013.
B. Mitch Seavey, who operates a touring business, is a New England immigrant.
C. Mitch Seavey won the Iditarod Trail Sled Dog Race in 2004 and 2013.
D. Mitch Seavey managed to help his son become the youngest winner in 2012.
2.On which day did Mitch Seavey probably win the champion in the 2013 Iditarod?
A. On Saturday, March 2. B. On Monday, March 11.
C. On Saturday, March 9. D. On Tuesday, March 13.
3. Who ranked the 2nd place in the 2013 Iditarod according to the passage?
A. Aliy Zirkle. B. Dallas Seavey.
C. Mitch Seavey. D. Jeff King.
4. According to the passage, we can learn that ________.
A. the sled-dog race is the most important sports event in the US
B. experience also has a major influence on the result of the race besides age
C. men and women can’t compete in the sled-dog race together at the same time
D. all the athletes in the sled-dog race are limited by age to win the sled-dog race
