5．We sometimes think global warming or climate change is a problem very far away from our lives，and that only the government needs to worry about it．But it's hardly possible to completely stay out of it-scientists are now 95percent sure that humans have been the"dominant cause"of global warming trends since the 1950s．
One of the conclusions of a report released on Sept 27by the United Nations says that human activities have caused global temperatures to rise by 0.89 0C between 1901and 2012．That might not seem like a lot，but the truth is that a major part of that heat has been absorbed into the oceans，which is not surprising given that they cover two thirds of Earth's surface．Also，water has a much greater capacity （容量） to absorb heat than the air does，according to The Economist．
While many greenhouse gases occur naturally and are needed to keep the Earth warm enough to support life，humans'use of fossil fuels is the main source of excess （多余的） greenhouse gases．According to CNN，by driving cars，using electricity produced by burning coal and oil or heating our homes with coal or natural gas，we release a large amount of greenhouse gases into the atmosphere．
Your body can barely feel a difference of 0.89 0C，but the Earth's ecosystems are so sensitive that even small changes can disturb them．It often starts with the smallest creatures at the bottom of the food chain，eventually affecting bigger animals，many of which could end up becoming extinct．
Global warming is also linked to an increase in extreme weather．A larger amount of carbon dioxide traps more energy inside the atmosphere．This changes the patterns of storms and rainfall in many regions and can lead to droughts and floods．Worse still，melting sea ice in warmer oceans is causing sea levels to rise at a speed of more than three millimeters per year，according to The Guardian，which also increases the risk of flooding．
"The report should serve as another wake-up call that our activities today have a profound impact on society，not only for us，but for many generations to come，"French Michel Jarraud，secretary-general of the World Meteorological Organization，said at a news conference．

68．The underlined word"dominant"in the first paragraph means"D"．
A．common     B．indirect    C．secondary    D．leading
69．Which of the following statements is TRUE according to the passage？C
A．Greenhouse gases have been proven to harm merely the Earth．
B．There is little we can do to prevent global warming．
C．Global warming can increase the chances of droughts and floods．
D．The hugeness of oceans makes them better absorbers of heat than the air．
70．The rise in global temperatures between 1901 and 2012D．
A．is more harmful to smaller creatures than bigger ones
B．is not serious because most of the extra heat has been absorbed by the oceans
C．has made the Earth's ecosystems more sensitive to changes
D．is likely to cause many species to become extinct
71．What is Michel Jarraud's attitude toward the report released by the UN？B
A．Negative． B．Supportive． C．Doubtful． D．Uninterested．

分析 本文主要講述了全球變暖不是只有政府才關(guān)心的事，它與我們每個人都息息相關(guān)．科學(xué)家認為人類是20世紀50年代以來全球變暖的主要原因．全球變暖可能會導(dǎo)致干旱和洪水，使很多物種滅亡．因此，我們應(yīng)該敲響警鐘，愛護環(huán)境．

解答 68．D 詞義辨析題．根據(jù)第一段But it's hardly possible to completely stay out of it-scientists are now 95percent sure that humans have been the"dominant cause"of global warming trends since the 1950s．可知現(xiàn)在科學(xué)家可以95%確定人類是20世紀50年代以來全球變暖的主要原因．由此推知，"dominant"的意思是"主要的"．故選D．
69．C 細節(jié)理解題．根據(jù)第五段This changes the patterns of storms and rainfall in many regions and can lead to droughts and floods．可知全球變暖改變了許多地區(qū)的風(fēng)暴和降雨模式和可能導(dǎo)致干旱和洪水．故選C．
70．D 細節(jié)理解題．根據(jù)第四段It often starts with the smallest creatures at the bottom of the food chain，eventually affecting bigger animals，many of which could end up becoming extinct．可知在1901年到2012年之間，全球氣溫上升可能會導(dǎo)致許多物種滅絕．故選D．
71．B 推理判斷題．根據(jù)最后一段The report should serve as another wakeup call that our activities today have a profound impact on society，not only for us，but for many generations to come．可知Michel Jarraud認為聯(lián)合國的報告對我們有提醒作用，所以是支持該報告的．故選B．

點評 本文考察學(xué)生的理解推斷能力以及細心程度，只要抓住文章的關(guān)鍵詞，采用尋讀的方法查找細節(jié)，就能找到正確答案．

13．Foxes and farmers have never got on well．These small dog-like animals have long been accused of killing farm animals．They are officially classified as harmful and farmers try to keep their numbers down by shooting or poisoning them．
Farmers can also call on the services of their local hunt to control the fox population．Hunting consists of pursuing a fox across the countryside，with a group of specially trained dogs，followed by men and women riding horses．When the dogs eventually catch the fox they kill it or a hunter shoots it．
People who take part in hunting think of as a sport； they wear a special uniform of red coats and white trousers，and follow strict codes of behavior．But owning a horse and hunting regularly is expensive，so most hunters are wealthy．
It is estimated that up to 100，000 people watch or take part in fox hunting．But over the last couple of decades the number of people opposed to fox hunting，because they think it is cruel，has risen sharply．Nowadays it is rare for a hunt to pass off without some kind of conflict between hunters and hunt saboteurs （阻攔者）．Sometimes these incidents lead to violence，but mostly saboteurs attempt to stop the hunt by misleading riders and disturbing the trail of the fox's smell，which the dogs follow．
Noisy conflicts between hunters and saboteurs have become so common that they are almost as much a part of hunting as running after foxes itself．But this year supporters of fox hunting face a much bigger threat to their sport．A Labor Party Member of the Parliament（議會），Mike Foster，is trying to get Parliament to approve a new law which will make the hunting of wild animals with dogs illegal．If the law is passed，wild animals like foxes will be protected under the ban in Britain．
31．Why are foxes considered as harmful animals？D
A．Because they can't get on well with farmers．
B．Because they are very cruel．
C．Because they are shot by hunters．
D．Because they kill farm animals．
32．British hunters have been hunting foxesA
A．for recreation                                     
B．for the benefit of the farmers
C．to limit the fox population                            
D．to show off their wealth
33．How do fox hunting saboteurs often prevent foxes being hunted？B
A．By means of violence
B．By confusing the fox hunters．
C．By taking illegal action
D．By making laws．
34．Which of the following statements is NOT true according to the passage？A
A．Only the rich can be regular fox hunters．
B．Hunters kill foxes by shooting or poisoning them．
C．Hunting foxes has some rules to follow．
D．More and more British people object to fox hunting．
35．What can be inferred from the last paragraph？D
A．Mike Foster is a firm supporter of fox hunting．
B．Fox hunters and saboteurs seldom have conflicts nowadays．
C．The law to ban hunting wild animals will be passed in Britain this year．
D．As a sport，fox hunting may disappear in Britain in the future．

10．When I was six years old，my mom told me that I could find anyone's number in the phone book．I used to look through the phone book for hours trying to find Michael Jordan's phone number．When I couldn't find it，I just dialed seven numbers．When someone answered，I'd ask，"Is that Michael Jordan？"Obviously，I always had the wrong number．
A year later I started playing basketball at my local recreation center．It was very big．I never thought in my wildest dreams that a basketball court could be inside a building．The recreation center had a special smell in it，sort of like hot rubber．I guessed it was from the shoes hitting the floor so fast and hard．The atmosphere on the court was carefree．Our biggest excitement of the day was when we actually made a shot．We celebrated wins over ice cream at a fast food restaurant．
I got good at it，and my confidence grew．I played it all the time until the sixth grade．As soon as junior high school came，I stopped playing basketball and focused on school．When senior high school started，I tried out for the school team and made it．We worked hard．Every week we did 300 push-ups and 300 sit-ups on our own．Our coach encouraged the sit-ups to keep stomach power，because it gave us so much control when we were playing basketball．If we didn't want to do the sit-ups and push-ups，we could practice dribbling （運球） and shooting more．It's just us，the ball，the court and the net．But don't take my word for it．See for yourself．After all，I'm just one kid playing the game．

12．Recently，university students around the world were asked to volunteer in a global experiment called Unplugged．It was designed to see how young people would react if they were asked to observe a total media ban by unplugging all forms of media devices for 24 hours．
Unplugged is being run by Dr Roman Gerodimos，a lecturer in Communication and Journalism at Bournemouth University．During the experiment，Dr Gerodimos said there were already  signs of how much the exercise affected volunteers．He said："They're reporting withdrawal symptoms，overeating，feeling nervous，isolated and disconnected．"
During their 24-hour test，three of the experiment's participants were followed around by a BBC reporter plus cameraman．They were asked to write down 100 lines about their day offline，but of course，they all waited until the next day when they had access to their laptops．
Elliot Day wrote："Today，my whole morning routine was thrown up into the air．Despite being  aware of the social importance of the media，I was surprised by how empty my life felt without the radio or newspapers．"
From Caroline Scott，we read："I didn't expect it，but being deprived of the media for 24 hours resulted in my day-to-day activities becoming so much harder to carry out than usual…I didn't break out in a cold sweat like our lecturer expected us all to，but It's not something l would like to do again！"
And Charlotte Gay wrote："I have to say the most difficult item for me to be without has been  my  mobile；not  only is it a social device，it's  my main access point of communication．"
Earlier in the year，a UK government study found that in the UK we spend about half our waking hours using the media，often plugged into several things at once．So，with technology continuing to develop at an alarming rate，how much time will you set aside for sleep in the future？
71．What can we learn about the volunteers？B
 A．Volunteers didn't write down about their day offline．
 B．Volunteers weren't allowed to use any media for 24 hours．
 C．Volunteers  were followed around by Dr Roman Gerodimos．
 D．Only volunteers in the UK took part in Unplugged experiment．
72．Which of the following is NOT mentioned about the participants'feelings？
D 
A．Anxious．  B．Lonely  C．Bored．   D．Despaired．
73．Which of the following is true of Caroline Scott？C
 A．The media ban affected his temperature．
 B．His work went on smoothly without the media．
 C．His work was carried on hard without the media．
 D．His life was empty without the radio or newspapers．
74．What can be inferred from the last paragraph？A
 A．People should use the media devices reasonably．
 B．People can easily survive the media devices addict．
 C．People can spend more time sleeping in the future．
 D．People spend about half the time using the media devices．
75．The text is most probably a．C
 A．newspaper ad     
B． book review
 C．news report   
D．science fiction story．
