4．Almost 80% of the Americans have stated their opposition to cloning pet animals such as cats and dogs，yet companies still try to make a business out of selling cloned pets．Pet cloning has been promoted as a way to"bring back"or"copy"a beloved companion animal．However，studies have shown that cloning remains an experimental technology with many failures．
Behind each lovely picture of a cloned cat or dog lie hundreds of animals that were kept in lab cages，receiving bad treatment to produce just that one cloned animal．For all that，you end up with a cloned animal who is unlikely to appear like the original physically or behaviorally and may experience serious health problems．Also，while pet cloning companies are charging customers up to﹩150，000 for a cloned pet，millions of homeless animals of the same species are available in US animal shelters for around﹩100．Unfortunately，most of these animals are killed for lack of adopting homes．
With No Pet Cloning campaign，the American Anti-Vivisection Society （AAVS） tries to protect both animals and people from harm．They campaigned until the US companies that sold cloned animals closed their doors．First it was Genetic Savings & Clone Inc．and then it was BioArts International．
When BioArts was closed，its owner，Lou Hawthorne，finally had to acknowledge the problems of pet cloning．According to Hawthorne，he has seen numerous failures during his pet cloning attempts，"One clone----which was supposed to be black and white----was born greenish-yellow where it should have been white （we still have no good explanation for how that happened）．"
The AAVS is educating the public about the animal suffering and is seeking regulation of cloning activities．They will continue to take the lead in protecting animals from the threats of pet cloning．

61．From the passage，we know thatC．
A．pets are often deserted by their owners
B．more and more people have joined the AAVS
C．most American are against cloning pet animals
D．the American Anti-Vivisection Society is supported by the government
62．According to the passage，companies keep on selling cloned pets toB．
A．carry on scientific studies
B．get economic interests
C．protect pet animals
D．comfort animal lovers
63．What does the author try to do by writing the second paragraph？A
A．To tell the truth behind pet cloning．
B．To show the method of pet cloning．
C．To compare pet animals with homeless ones．
D．To save the animals kept in labs and shelters．
64．The underlined word"acknowledge"probably meansC．
A．accept B．study C．admit D．manage
65．According to the passage，the AAVS devotes itself toD．
A．getting most countries to fight against pet cloning
B．improving the technology of pet cloning
C．saving lots of animals from bad situations
D．stopping US companies'selling cloned animals．

分析随着克隆技术的发展，猫狗等宠物也可以被克隆．但是大多数美国人反对这一做法，美国一些动物保护组织，如AAVS，力图保护人类和动物不受伤害．

解答 61-65 CBACD
61．C 推理判断题．根据第一段Almost 80% of the Americans have stated their opposition to cloning pet animals such as cats and dogs80%的美国人表明他们反对克隆宠物，如狗和猫等．故选C项．
62．B 细节理解题．根据第一段companies still try to make a business out of selling cloned pets．一些公司仍然售卖克隆宠物挣钱，获得经济利益．故选B项．
63．A细节理解题．根据第二段第一段Behind each lovely picture of a cloned cat or dog lie hundreds of animals that were kept in lab cages，receiving bad treatment to produce just that one cloned animal．在克隆猫或狗的美妙图景背后，是为了生产克隆动物，无数的动物被关在实验室的笼子里，接受不良待遇这一事实．故选A项．
64．C词义猜测题．根据下句According to Hawthorne，he has seen numerous failures during his pet cloning attempts．据Hawthorne所说，他亲眼目睹了宠物克隆实验过程中的无数次失败，可知，他终于承认宠物克隆存在的问题．故选C项．
65．D推理判断题．根据最后一段They will continue to take the lead in protecting animals from the threats of pet cloning．他们将继续保护动物，避免宠物克隆的威胁．故选D项．

14．Scientists have found we are more likely to die on our birthday than any other day．Researchers who studied more than two million people over 40years found a rise in deaths from heart attacks，strokes（中风），falls and suicides（自杀）and others on that day．
On average，people over the age of 60were 14per cent more likely to die on their birthdays．Heart attacks rose 18.6per cent on birthdays and were higher for men and women while strokes were up 21.5per cent-mostly in women．
Dr Vladeta Ajdacic of the University of Zurich said："Birthdays end dangerously more frequently than might be expected．"He added that risk of birthday death rose as people got older．
Canadian data also showed that strokes were more likely on birthdays，especially among patients with high blood pressure．
There was a 34.9per cent rise in suicides，28.5per cent rise in accidental deaths not related to cars，and a 44per cent rise in deaths from falls on birthdays．
Psychologist Professor Richard Wiseman，from the University of Hertfordshire，said，"It seems to be a reliable finding．There are two cases-one is the case that suggests you eat too much and your getting over excited and that causes you to die．"He said continuously，"The other is a placebo effect（安慰剂效应）．You are knife-edged on death．And you kept yourself going until your birthday．You think‘That's it．I've had enough．I'm out of here．'"
Dr Lewis Halsey，of the University of Roehampton，said，"One interesting finding is that more suicides happen on birthdays，though only in men．Perhaps men are more likely to make a statement about their unhappiness when they think people will be taking more notice of them．"

59．Which sentence can properly be put at the beginning of the passage？D
A．Be happy on your birthday．
B．Be ready to care for others．

15．There have always been a lot of commonly believed but false ideas about being fat and doing exercise．Some people believe that they can't help putting on weight as they get older，while others hold that if they stop exercising，their muscles will turn into fat．Here are some more myths：
I'll never lose weight---I come from a fat family
Wrong!While we can't change the body type we are born with，we can't blame our genes for making us fat．There's plenty of evidence that fatness runs in families，and the main reason is that they share the same habits of eating too much and exercise too little．
I am fat because I burn calories slowly
Wrong!Fatness is not caused by a slow metabolism（新陈代谢）．If fact，although fat people consume more energy that slim people，they also fail to realize how much they eat!Keeping a diary can help you work out your daily food intake more accurately．
Exercise is boring
Wrong!Anything will become boring if you do it repetitively．The key is to develop a balanced and varied program that's fun as well as progressive．If you enjoy a Sunday walk，take a different route．If you do Yoga，try a tai chi class．If you like swimming，set a distance or time challenge．
No pain，no gain．
Wrong!Exercise is not meant to hurt．Indeed，pain is your body telling you something's wrong，and continuing to exercise could lead to serious injury．You may experience mild discomfort as you begin to exercise regularly，but when your body adapts to the positive changes in your lifestyle and the aches should disappear relatively quickly．If you don't，rest and seek medical advice．

24．What does the author think about being fat？C
A．It is the family genes that make people fat．
B．People are fat because they consume too little energy．
C．It is the consequence of people's unbalanced lifestyle．
D．A diary of exercise can prevent people from becoming fat．
25．According to the author，how can we make exercise more interesting？A
A．By taking varied exercise．
B．By choosing simple exercise．
C．By doing regular exercise．
D．By sticking to outdoor exercise．
26．What is the author's opinion about"No pain，no gain"in exercising？A
A．Exercise should be stopped if continuous pain is felt．
B．Keeping fit is essentially a painful experience．
C．Pain in exercise is a precondition for reaching your goal．
D．Getting used to pain leads to positive changes in your body．
27．What is the purpose of the passage？D
A．To argue the importance of keeping fit．
B．To prove some medical facts about being fat and doing exercise．
C．To confirm what has long been believed about keeping fit．
D．To inform readers of some misunderstandings about fatness and exercise．

12．Driving in traffic can be extremely stressful．Pedestrians appear out of nowhere，cars suddenly pull out of parking spots，and roads become slippery due to rain or snow．Knowing when to brake and when to accelerate in such situations is hard enough for a human driver，let alone a robotic one．But several carmakers-and a few tech companies-are working to convince drivers to let driverless cars take the wheel．
       Without question，the most anticipated benefit of driverless cars is improved safety．Driverless systems will feature sensors that detect safety threats that human drivers might miss．Many carmakers already offer systems that alert drivers whenever they get dangerously close to other cars．
Also，driverless systems have the benefit of increased efficiency．Driverless cars won't waste as much gas as human drivers do，and guided by advanced GPS，they'll always take the fastest route．Once driverless cars become widely available，common people can have their own driver，and they'll just sit back and relax while their car's computer takes the wheel!
Although completely driverless cars won't be on the market for several years，the technology behind them is already appearing in phases．Two examples are the Active Lane Keeping Assist option for Mercedes-Benz cars and Ford's Traffic Jam Assist．In the first option，the system warns the driver whenever the car crosses lane markings by causing the steering wheel to vibrate（振动）．In the second option，the system helps the car keep pace with other cars while remaining in its current lane．The system is being developed to help relieve blocking on busy roads．
       Several carmakers claim that they'll produce driverless cars within the next decade．But critics aren't so sure，warning that a completely driverless car must be able to make split-second decisions in even the most complex traffic situations．In addition，the car's computer must become smart enough to know when to ask the driver to intervene （介入，干涉） to prevent an accident．
       Full government approval won't happen until driverless cars are proven safe．In the meantime，expect to see carmakers offer ever-smarter features on their new models．
（Note：Answer the questions or complete the statements in NO MORE THAN TWELVE WORDS）
78．One of the factors that make traffic extremely stressful is thepedestrians appearing out of nowhere/cars pulling out of parking spots/slippery roads due to rain or snow
79．What are the benefits of driverless system？Improved safety and increased efficiency
80．What will happen to a car with the Active Lane Keeping Assist when it crosses lane markings？The steering wheel will vibrate．
81．Driverless cars won't be on the market until they canmake split-second decisions and know when to ask the driver to intervene．

19．As women in the rich Asian country have become better educated，with five times as many now getting advanced degrees as in 1995，they have also become choosier and are less likely to settle for the role of gentle wife traditionally expected of Korean women．
"I heard if you are a female with master's degree，it is much harder to arrange a meeting than if you have a bachelor's degree because of an unfavorable concept'too smart women'here，"said King，a college senior in Seoul．
The age at which Korean women are getting hitchedhas risen by an average 4.1 years over the past 20 years to 28.9 years，according to Statistics Korea，and that has created worried mothers getting things rolling for their daughters．

"In a privately set-up blind date，you cannot be entirely sure of how much of personal information given to you is accurate，"said DUO spokesman Yon Jun．
Critics say the industry focuses more on income and status．Some of them have coined the phrase"employage"to sum up employment and marriage．
"If your father works in the financial industry or is a high-ranking administrator，maybe you will find your match with similar backgrounds through a matchmaking firm，starting a perfect marriage on the back of parental support，"said comedian Quan．

63．The underlined word"hitched"in Paragraph 3 probably meansB．

9．People with an impulsive personality refer to those who tend to do things without considering the possible dangers or problems first．According to a new study by researchers at the University of Georgia，such people may be more likely to have food addiction．The study found that people exhibiting impulsive behavior weren't necessarily overweight，but impulsiveness was related to a direct relationship with food，and therefore，less healthy weight．
Food addiction has been compared to addictive drug use．Studies have linked the dopamine （多巴胺） release that occurs after tasting delicious food to the dopamine release that happens when people consume other addictive substances．
Impulsive behavior involves several personality traits （特点）．Two of these traits，known as negative urgency and lack of perseverance，were particularly associated with food addiction and high BMI （身体质量指数） during the study．
Negative urgency is characterized by the tendency to behave impulsively when experiencing negative emotions．Some people might drink alcohol or take drugs．For others，it could mean eating to feel better．Lack of perseverance is when a person has a hard time finishing hard or boring tasks．People with a lack of perseverance might have difficulty attempting to change addictive eating behavior，which could also cause obesity．
"Impulsiveness might be one reason why some people eat in an addictive way despite motivation to lose weight，"said Dr．Ashley Gearhardt，a clinical psychologist．He was involved in developing the Yale Food Addiction Scale in aid of those people．"We are theorizing that if food addiction is really a thing，then our measure，the Yale Food Addiction Scale，should be related to helping control impulsive action，"said Gearhardt．
Clinical psychologist Dr．James MacKillop，whose lab was conducting the study，believes that therapies used to treat addictive drug behavior could help people who suffer from addictive eating habits．
"Most of the programs for weight loss at this point focus on the most obvious things，which are clearly diet and exercise，"MacKillop said．"It seems that managing strong desires to eat would naturally fit in with the skills a person would need to eat healthily．"

12．According to Paragraph 1，the result of food addiction isA．
A．less healthy weight B．motivation to lose weight
C．negative emotions    D．taking alcohol or drugs
13．How does the author introduce the two personality traits in Paragraph 4？D
A．By making comparisons and conclusions． B．By explaining causes and effects．
C．By presenting questions and answers．   D．By giving definitions and examples．
14．What can be inferred about the Yale Food Addiction Scale from the text？B
A．It has been successfully carried out among overweight people．
B．It might help some impulsive people with food addiction to lose weight．
C．It will prove whether food addiction is a problem to impulsive people．
D．It is theoretically a proper treatment for addictive food and drug behavior．
15．Which of the following can be the best title for the text？C
A．Dopamine release caused by food addiction
B．Food addiction compared to drug use
C．Impulsive personality linked to food addition
D．Food addiction contributing to obesity．
