In the eyes of dog lovers, the dog is man’s best friend. But for much wildlife, loose dogs may be a dangerous enemy, according to a study by a biologist from Utah State University in the US.
Based on much existing research and their own case studies, Julie Young of Utah State University and four other scientists conclude that loose dogs may represent a huge danger to wildlife, especially endangered species, by hunting down or worrying them and by spreading diseases. They also found that dogs, their worldwide numbers around 500 million, can cause more damage to wildlife and livestock(牲畜) than wolves and other enemies of these animals.
Young gave examples from the US state of Idaho, where research showed the presence of dogs reducing some deer populations. On the Navajo American Indians’ reservation in northeastern Arizona, packs of loose dogs are chasing livestock. They have killed populations of small animals such as rabbits and act as a disease carrier for rabies(狂犬病) among people and other animals, she said. Loose dogs also were to blame for distemper outbreak leading to a die-off of endangered black-footed ferrets in northwestern Wyoming in the 1980s.
The phenomenon is not just limited to US; it’s a global problen. Julie Young once studied three endangered species in central Asia: wild sheep, gazelles and antelope. The rate of injury and death to these animals by loose dogs was very high. In another case, Young found that dogs, not wolves, as originally suspected, were responsible for a large number of livestock killings in the mountainous Basq
ue country between Spain and France.
Authors of the new study said the problem is likely to worsen as communities expand. Then how to deal with it?
Indeed, in many countries, leash(拴狗的皮带) laws permit punishment of dog owners whose pets chase wildlife. But lawbreakers are rarely punished because the police lack both people and money.
Young has low-cost solutions to the problem for dog lovers, though. They include public dog-training programs and vaccinating (预防接种) dogs against rabies and other illnesses.What is the main point of Julie Young’s study?
A. Many species are endangered because they are killed by loose dogs.
B. Wild dogs are immune to many diseases.
C
. Wolves are still the greatest enemy of livestock.
D. Loose dogs pose a great danger to wildlife.Which of the following statements about loose dogs is TRUE according to the research?

| B．The black-footed ferrets in northwestern Wyoming were once the main food source of local loose dogs. |
| C．The problem caused by loose dogs is the most serious in the US. |
| D．People used to think that wolves, rather than loose dogs killed livestock in the Basque country. |
Which of the following is among Julie Young’s solutions to the trouble caused by loose dogs?
| A．More strict leash laws |
| B．Public dog-training programs. |
| C．Vaccinating people against rabies and other illnesses. |
| D．More support from the police. |
What is the main point of the article?
| A．A global disaster caused by loose dogs. |
| B．What makes the dog man’s greatest friend. |
| C．The problem of loose dogs and the possible solutions. |
D．The dan ger of the increasing numbers of dogs. |
Last year my wife and I spent a most interesting month in Turkey. Before we left, we were reminded of the difficulties of driving in Turkey. We certainly did not find this to be the case and, except for a few places in faraway mountainous areas, the roads were wide, and well-paved (铺). We drove for 12 days along the Western Coast of Turkey and had no problems at all. We found the Turkish drivers very polite and well-educated. We also found that eating lunch in the smaller towns was difficult so we picnicked almost every day.
The following day after our arrival was Turkey’s Children’s Day, started by Mustafa Kemal Ataturk. Ataturk loved children and he often said, “Children are a new beginning of tomorrow.” He even devoted the day 23rd of April to the children which today is celebrated as Children’s Day as well as the date when the Republic of Turkey was founded.
On that day certain children are picked to take over the places of the government, and a lucky kid will be the president of Turkey for a whole day. He can decide what’s going to happen and whether or not he is going to have the president next to him. There are a very large number of possibilities of things he can do but some shops aren’t open because they are celebrating the day as well.
All in all, it was a more enjoyable trip. I would recommend (推荐) a trip to Turkey to anyone with an adventurous spirit! Before the author and his wife went on a trip to Turkey, they were told that ________.
| A．it was difficult to travel in Turkey |
| B．it was not easy to drive in Turkey |
| C．the streets in Turkey were dangerous |
| D．there were many mountain roads |
What do we know from the first paragraph?
| A．Places in mountainous areas were difficult to reach. |
| B．It took the couple 12 days to drive to Turkey. |
| C．The Turkish drivers had good manners. |
| D．It was difficult to eat meals in Turkey. |
The underlined word “He” in paragraph 3 refers to “________”.
| A．everyone of us | B．the government |
| C．the president of Turkey | D．the lucky child |
What can be inferred(推断) from the passage?
| A．The couple had little difficulty making their way in Turkey. |
| B．Turkey doesn’t celebrate International Children’s Day. |
| C．The author joined in celebrating Turkey’s Children’s Day. |
| D．On Turkey’s Children’s Day, everyone had holidays. |
Every year on my birthday, from the time I turned 12, a white gardenia was delivered to my house. N
o card came with it. Calls to the flower-shop were not helpful at all. After a while I stopped trying t
o discover the sender’s name and just delighted in the beautiful white flower in soft pink paper.
But I never stopped imagining who the giver might be. Some of my happiest moments were spent daydreaming about the sender. My mother encouraged these imaginings. She’d ask me if there was someone for whom I had done a special kindness. Perhaps it was the old man across the street whose mail I’d delivered during the winter. As a girl, though, I had more fun imagining that it might be a boy I had run into.
One month before my graduation, my father died. I felt so sad that I became completely uninterested in my upcoming graduation dance, and I didn’t care if I had a new dress or not. But my mother, in her own sadness, would not let me miss any of those things. She wanted her children to feel loved and lovable. In truth, my mother wanted her children to see themselves much like the gardenia－lovely, strong and perfect with perhaps a bit of mystery (神秘).My mother died ten days after I was married. I was 22. That was the year the gardenia stopped coming.
Which of the following would be the best title 
for the text?
| A．A Childhood Dream | B．A Mother’s Love |

The mother insisted that her daughter go to the graduation dance because ________.
| A．she could take care of things herself |
| B．she hoped she would find a boyfriend |
| C．she wanted her to be happy and strong |
| D．she thought education was the most important |
Who was the sender of the flower?
| A．A boy the writer had run into. | B．One of the writer’s neighbors. |
| C．One of the writer’s classmates. | D．The writer’s mother. |
For years, there has been a bias (偏见) against science among clinical psychologists (临床心理学家). In a two-year analysis to be published in November in Perspectives on Psychological Science, psychologists led by Timothy B. Baker of the University of Wisconsin charge that many clinical psychologists fail to “provide the treatments for which there is the strongest evidence of effectiveness” and “give more weight to their personal experiences than to science.” As a result, patients have no guarantee that their “treatment will be informed by … science.” Walter Mischel of Columbia University is even crueler in his judgment. “The disconnect between what clinical psychologists do and what science has discovered is an extreme embarrassment,” he told me, and “there is a widening gap between clinical practice and science.”
The “widening” reflects the great progress that psychological research has made in identifying (确认) the most effective treatments. Thanks to strict clinical trials, we now know that teaching patients to think about their thoughts in new, healthier ways and to act on those new ways of thinking are effective against depression, panic disorder and other problems, with multiple trials showing that these treatments — the tools of psychology — bring more lasting benefits than drugs.
You wouldn’t know this if you sought help from a typical clinical psychologist. Although many treatments are effective, relatively few psychologists learn or practice them.
Why in the world not? For one thing, says Baker, clinical psychologists are “very doubtful about the role of science” and “lack solid science training”. Also, one third of patients get better no matter what treatment (if any) they have, “and psychologists remember these successes, believing, wrongly, that they are the result of the treatment.”
When faced with evidence that treatments they offer are not supported by science, clinical psychologists argue that they know better than some study what works. A 2008 study of 591 psychologists in private practice found that they rely more on their own and colleagues’ experience than on science when deciding how to treat a patient. If they keep on this path as insurance companies demand evidence-based medicine, warns Mischel, psychology will “discredit itself.”Many clinical psychologists fail to provide the most effective treatments because ________.
| A．they are unfamiliar with their patients | B．they believe in science and evidence |
| C．they depend on their colleagues’ help | D．they rely on their personal experiences |
The widening gap between clinical practice and science is due to _______.
| A．the cruel judgment by Walter Mischel |
| B．the fact that most patients get better after being treated |
| C．the great progress that has been made in psychological research |
| D．the fact that patients prefer to take drugs rather than have other treatments |
How do clinical psychologists respond when charged that their treatments are not supported by science?
| A．They feel embarrassed. | B．They try to defend themselves. |
| C．They are disappointed. | D．They doubt their treatments. |
In Mischel’s opinion, psychology will ____.
| A．destroy its own reputation if no improvement is made |
| B．develop faster with the support of insurance companies |
| C．work together with insurance companies to provide better treatment |
| D．become more reliable if insurance companies won’t demand evidence-based medicine |
We keep reading that TV is bad for you. If this is true, how come the cur
rent generation of TV-addicted kids is much smarter than we are? In my home, the only people who can work the remote control are the children.
Perhaps TV does educate you. For example, you learn a useful medical fact: A person who has been shot always has time to speak an incomplete sentence before he dies. “The killer was…” (dies)
But I guess the biggest things we learn from TV can be regarded as “Life Skills”. Bad things only happen on dark and stormy nights. Emotional breakdowns cause people to wander in the heavy rain without umbrellas. And contrary to what scientists say, the crack(霹雳) of lightning and the accompanying flash happen at exactly the same time, wherever you are.
I’ve even acquired useful geographical facts from science-fiction shows: Aliens speak English no matter which planet they come from.
Making use of what we learn from TV can improve our security. Consider these truths. If you are ever attacked by 20 bad guys, don’t worry about being outnumbered. The criminals will hang back and take turns to approach you in ones and twos just so you can conveniently defeat them all. Bad guys who are completely covered in black clothes always remove their black masks to reveal that they are in fact, aha, women.
TV also teaches us important information about escaping from danger. Watch and learn. (1) If anyone is running after you down a passage, you will find that boxes have been conveniently placed near all the walls you need to jump over. (2) If you are tall and handsome, you can run from any number of armed criminals, and every shot will miss you.
Be warned, however. If your name card says “henchman” (帮凶) and you are part of a group of plain-looking people trying to catch a handsome individual, a single shot will kill you. But don’t be anxious: TV also delivers useful information for bad guys. All cars are inflammable (易燃的) and have amazing shock absorbers that enable them to fly into the air and land without damage — except police cars.
TV even teaches us about TV. Whenever anyone turns on a TV, it shows a news flash about someone they know. They then turn the box off immediately after that news item.By saying “A person who has been shot always has time to speak an incomplete sentence
before he dies” (Paragraph 2), the writer shows his________.
| A．humor | B．sympathy |
| C．deep concern | D．medical knowledge |
We can infer from Paragraph 3 that in the real world_______.
A．bad things cause people to break down in the ra in |
| B．bad things never happen on dark and stormy nights |
| C．people with emotional problems like to walk in the rain without umbrellas |
| D．the crack of lightning and the accompanying flash don’t happen at the same time |
On TV what usually happens when a person turns it on?
| A．The news shown is always about someone the person knows. |
| B．The person always turns off the TV when it’s time for news. |
| C．The program shown is always about the importance of TV. |
| D．TV always shows news about famous people. |
What’s the main idea of this passage?
| A．Life skills can be learned from TV. |
| B．TV plays an important role in society. |
| C．Watching TV makes people more creative. |
| D．What happens in TV is very different from reality. |
One of the most widely accepted, commonly repeated assumptions (假设) in our culture is that if you exercise, you will lose weight. I exercise all the time, but I still have gut fat that hangs over my belt when I sit. Why isn’t all the exercise getting rid of it?
It’s a question many of us could ask. More than 45 million Americans now belong to a health club, up from 23 million in 1993. We spend some $19 billion a year on gym memberships. Of course, some people join and never go. Still, as one major study — the Minnesota Heart Survey — found, more of us at least say we exercise regularly.
And yet obesity (肥胖) figures have risen sharply in the same period: a third of Americans are obese, and another third count as overweight by the Federal Government’s definition. Yes, it’s entirely possible that those of us who regularly go to the gym would weigh even more if we exercised less. But like many other people, I get hungry after I exercise, so I often eat more on the days I work out than on the days I don’t. Could exercise actually be keeping me from losing weight?
The popular belief that exercise is essential for weight control is actually fairly new. As recently as the 1960s, doctors routinely advised against too much exercise, particularly for older adults who could injure themselves. Today doctors encourage even their oldest patients to exercise, which is sound advice for many reasons: People who regularly exercise are at significantly lower risk for all manner of diseases — those of the heart in particular. They less often develop cancer and many other illnesses. But the past few years of obesity research show that the role of exercise in weight loss has been wildly over-evaluated.
“In general, for weight loss, exercise is pretty useless,” says Eric Ravussin, exercise researcher at Louisiana State University. Many recent studies have found that exercise isn’t as important in helping people lose weight as you hear so regularly in gym advertisements or on shows like The Biggest Loser — or, for that matter, from magazines like this one.
The basic problem is that while it’s true that exercise burns calories and that you must burn calories to lose weight, exercise has another effect: it can make one hungry. That causes us to eat more, which in turn can negate (使无效) the weight-loss benefits we just gained. Exercise, in other words, isn’t necessarily helping us lose weight. It may even be making it harder. From the passage we learn that ____.
| A．some Americans join a health club but never go there |
| B．the number of overweight people has doubled since 1993 |
| C．more than 45 million Americans now go to the gym regularly |
| D．Americans waste too much money each year on sports |
According to the passage, exercise ____.
A．has long been believed to be good for older adults |
| B．is not properly advertised as an effective way to lose weight |
| C．was first recognized as an effective way to lose weight in the 1960s |
| D．is less effective in preventing heart disease than what doctors believe |
According to the writer, people might gain weight because ____.
| A．they have the habit of going to the gym regularly |
| B．they eat the same food when they do not exercise |
| C．they exercise less than required by doctors |
| D．they eat more after they exercise |
What may be the best title for this passage?
| A．Overweight Is Not Good for Your Health |
| B．Exercise Won’t Make You Thin |
| C．Gym Is Part of American Lifestyle |
| D．Obesity Is a Social Problem in America |
