1．It would be very safe if you      the door        to the garden．（　�。�
A．fasten；ledB．will fasten；leads
C．fastened；leadingD．fastened；to lead

分析 如果你將通往公園的門加固，那會很安全的．

解答 答案：C
根據(jù)句意可知，本句是虛擬條件句；由于主句使用了"would+動詞原形"，故if從句表達的應(yīng)是與現(xiàn)在事實相反的情況，需要使用一般過去時fastened；"        to the garden"在句中作名詞door的后置定語，由于該名詞與動詞lead構(gòu)成了主謂關(guān)系，意為"通往公園的門"；所以這里應(yīng)使用現(xiàn)在分詞形式；故選C．

點評 本題考查虛擬條件句以及現(xiàn)在分詞作定語的用法；做本題時，首先應(yīng)根據(jù)句意以及主句謂語部分的表現(xiàn)形式，判斷出該句是虛擬條件句，表達的是與現(xiàn)在事實相反的情況；從而確定出從句應(yīng)使用的時態(tài)；因此，需要熟練掌握虛擬條件句的意義及用法；其次還應(yīng)掌握動詞的現(xiàn)在分詞的作定語的用法．

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（釋放）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．a(chǎn)nd 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 （紀律） 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．
64． According to the passage，the American teenage boys'lives are most threatened byA
A． gun murders 
B． natural diseases
C． TV violence                 
D． physical punishment
65． We can learn from Paragraph 4 thatD
A． many youth have watched much violence on TV
B． youth violence in Washington IX； is very serious
C． fights may be the most widely-seen youth violence
D． American youth have been exposed to much violence
66． The APA indicates that too much TV violence may change childrenB
A． to become separated from the world 
B． to remain unconcerned about others'pain
C． to solve problems only by violence 
D． to be fearful of aggressive behaviors
67． The author may most probably agree that physical punishment isC
A． acceptable，though ineffective          
B． illegal，though effective
C． harmful，though legal                 
D． reasonable，though illegal．

8．American this year will swallow 15，000 tons of aspirin，one of the safest and most effective drugs invented by man．The most popular medicine in the world today，it is an effective pain reliever．Its bad effects are relatively mild and it is cheap．
For millions of people suffering from arthritis（關(guān)節(jié)炎）．It is the only thing that works．Aspirin，in short，is truly the 20th-century wonder drug．It is also the second largest suicide drug and is the leading cause of poisoning among children．It has side effects that，although relatively mild，are largely unrecognized among users．
Although aspirin was at first sold by a German company in1899，it has been around much longer than that．Hippocrates，in ancient Greek，understood the medical value of the leaves and tree bark which today are known to contain salicylates（水楊酸堿），the chemical in aspirin．During the 19th century，there was a great deal of experimentation in Europe with this chemical，and it led to the introduction of aspirin．By 1915，aspirin tablets were available in the United States．
A small quantity of aspirin （two-grain tablets） relieves pain and inflammation．It also reduces fever by interfering with（干預(yù)） some of the body's reactions．

41．The passage is written toC．
A．suggests us using more aspirin         B．reminds us of the side effects of aspirin
C．gives us a whole view of aspirin       D．discusses the good effects of aspirin
42．According to the author，aspirinC．
A．is very safe                          B．first appeared in 1899
C．can be harmful to children            D．can hardly be dangerous
43．Generally speaking，the author seems to beA．
A．in favour of aspirin                    B．a(chǎn)gainst the use of aspirin
C．not interested in aspirin               D．careful in using aspirin
44．What is the best title for this passage？C
A．How to Use Aspirin                   B．Why I Take Aspirin
C．The Most Popular Medicine            D．The Side Effects of Aspirin．
