9．BANGKOK-The tiny island nation of Tuvalu has promised to do its part for climate change by fueling its economy entirely from renewable sources by 2020．
The South Pacific nation of 12，000people is part of a movement of countries and cities committed to going climate neutral．Since February 2008，10nations have promised to reduce their emission（释放）of greenhouse gases as part of a goal of reaching zero emissions in the next decade．
None of these commitments alone is expected to make a significant difference in the fight to cut heat-trapping gases．But the moves can inspire bigger emitters（排放者）like the United States to take further steps to limit their carbon footprints．
Climate scientists have urged rich countries to reduce emissions from 2005levels by between 25percent and 40percent by 2020to avoid the worst effect of warming．For its parts，Tuvalu hopes to replace the fossil fuels that are imported by ship with solar energy and wind power soon．
Tuvalu already emits almost no greenhouse gases．But because of climate change，many South Pacific islands see worsening flooding．The country is just 10square miles in size，with most of its land less than a meter above sea level．
So far，Tuvalu has equipped a 40-kilowatt solar energy system with the help of Japan's Kansai Electric Power Co．and Tokyo Electric Power Company．The Tuvalu government is working to expand the $410，000project from 40to 60kilowatts，and will extend solar power to outer islands．
"We thank those countries who are helping Tuvalu reduce its carbon footprint，"Public Utilities and Industries Minister Kausea Natano said．"And we look forward to the day when our nation offers an example to all-powered entirely by natural resources such as the sun and the wind．"

53．What is the main energy source in Tuvalu at present？B
A．Solar energy
B．Imported fossil fuels
C．Wind powder
D．Local fossil fuels
54．For Tuvalu，the biggest trouble now is thatA．
A．it is under threat from rising sea level
B．it lacks enough natural resources
C．Climate change affects its economy
D．it lacks clean power equipment
55．What can we learn from the passage？C
A．It is impossible for Tuvalu to realize its goal．
B．The world will see zero emissions in ten years．
C．Tuvalu imports technology to reduce emissions．
D．Big countries haven't started to reduce emissions．
56．The best title for the passage might be"D"．
A．Climate change threatens small island nations
B．island nations urge big countries to reduce emission
C．Countries unite to reduce greenhouse gases
D．An island nation will only use green power．
16．Teenage boys，regardless of race，are more likely to die from gunshot wounds than from all natural causes combined，
By the time the average American child leaves primary school，he or she will witness 8，000 murders and more than 100，000 acts of violence on televisionYouth are becoming involved in violence at an alarming rate． In fact，the young arrest rate for murder doubled，from 6 arrests per 100，000 youth aged from 10 to 17 to over 12 per 100，000For the many youth who have not been directly exposed to violence in their own communities，the entertainment media （television，movies，music and video games） provides many opportunities for children to see and hear violent exchanges． Research shows that there are about 5～6 violent acts per hour on prime time and 20～25 violent acts on Saturday morning  children's programming． In its report，the American Psychological Association （APA） reported that viewing violence on television hurts children in many ways． In particular，the APA  concludes that children may become less sensitive to the pain and suffering of others，be more  fearful of the world around them，be more likely to behave in aggressive or harmful ways toward others，and gradually accept violence as a way to solve problems．
Another form of violence involving youth is physical punishment in the schools． This form of discipline （纪律） still remains legally supported in 23 nations in America． The Office for Civil Rights in the Department of Education reported that 555，000 students were physically punished in the schools during this school year． Although such punishment has been regarded as an effective method of discipline by those who apply it，the findings are obvious that physical punishment does not work and that children who are victims of physical punishment are subject to potential long-term physical and emotional damage．

11．New York times，Nov，24，2011-It is not just any bug，but the native nine-spotted ladybug．And its reappearance is something of a relief，because it is the official New York State insect，even though the last recorded sighting of it in New York was 29years ago．
Its absence had not gone completely unnoticed．There was a moment in 2006when the State Assembly，realizing that the state insect had left the state，tried to replace it with a different species of ladybug，an attempt that fortunately gave in to law．
And now-after all these years-the state insect has been found．Like so many other New Yorkers，it was seen summering in Amagansett．Peter Priolo，a volunteer participant in an effort called the Lost Ladybug Project，found the ladybug on July 30in a patch of sunflowers during a group search he had organized．
"I didn't realize it was a nine-spotted when I found it，"Mr．Priolo said．He was on his way to do an end-of-the-day ladybug record，so，he said，"I put it in my jar and hurried back to meet with everybody．"
If the ladybugs are making a comeback，it is only beginning．The lost Ladybug Project started surveys in 2000．As of 2006，only five nene-spotted ladybugs had been found in North America in the previous 10years，none of them in the East．Then one lone ladybug was found in Arlington，Va．None had been found in the East since，and only 90have been reported in North America．
After scientists at Cornell confirmed Mr．Priolo's find，they went to the Amagansett farm in mid-August to lead a search that turned up about 20more of the bugs．An area between rows of carrots and beans turned out to be a hot spot．"We found a lot of them on cosmos and zinnias，"said Dr．Losey said，an insect expert．The farm is part of the 10，000-acre Peconic Land Trust in Amagansett，and it is organic．For ladybugs，Dr．Losey said，"you couldn't design a better place．"
Dr．Losey wants to find out if it makes sense to reintroduce this strain of the ladybug in other areas．And he expects volunteers to be back out in the field when ladybug season starts again in the spring．Now，he said，"we need to find out more places where there are just as many．"

49．The last time the New Yorkers saw their state insect inD．
A．2000   B．2006   C．1998   D．1982
50．The New Yorkers are so delighted to see the insect becauseC．
A．it has some bright spots on its back
B．it is the official insect of the city
C．it had been out of sight for quite some time
D．it is a new species unknown to New York
51．What does the second paragraph of the passage imply？A
A．It's against the law to bring new insects to New York．
B．The State Assembly don't like to live with Ladybugs．
C．The absence of the state insect had never been known．
D．The state insect had to leave because of a new species．
52．From the last two paragraphs we know thatB．
A．only some insect experts are really interested in ladybugs
B．Dr Losey is quite confident about the future of the insect
C．most ladybugs have m moved to live in the down area
D．more vegetables will be grown to welcome the state insect．
