Your dog is as smart as any two year old, according to a new study. Dogs bring much happiness to their owners, and even improve human health. Most two-year-olds keep us busy in life - an important part of living a long and happy life. According to Stanley Coren, Ph.D.of the University of British Columbia, our dogs are smarter than we thought.

Dr. Coren reviewed many studies to find out that dogs are as smart as 2 to 2.5-year-olds. Forget about one word orders - according to Coren, the smartest dogs can learn up to 250 words. Most dogs understand an average of 165 words. “The upper limit of dogs, ability to learn language is partly based on a study of a Border Collie　 named Rico who showed knowledge of 200 spoken words，and ‘fast-track learning,’ which scientists believed to be found only in humans and language-learning apes (猿).”

Dogs are also great at tricking. During play, they have the ability to trick humans and other dogs in order to get treats. “And they are nearly as successful in tricking humans as humans are in tricking dogs,” says Coren.

Dogs can also count to four or five, which might explain how they know when their toys are missing. Coren explains, “Their astonishing flashes of smartness and creativity are reminders that they may not be Einsteins, but are sure closer to humans than we thought.”

Animals can do much to keep us happy, healthy, and protect us from harm. Stories of dog heroes can be found using a simple Internet search. Pets teach us sense of duty, keep us from loneliness,and can help with treatment of the disabled.

1.How do dogs bring happiness and health to humans according to the author?

A.By doing funny tricks. B.By keeping their owners busy.

C.By serving their owners. D.By playing with the children.

A dog's mind is only equal to that of a two-year-old baby. 1. So, they are probably the first to notice any change in the behavior of their masters. Let's do some deep-digging to understand the amazing ability of a dog.

They sense your feelings. Isn't it strange? 2. This is true. A study published in the Animal Cognition（认知）journal says that dogs are known to come to people who appear sad or depressed. It doesn't matter if the person is their owner or a stranger. They have an ability to sense sadness and are attracted to troubled souls.

3. Dogs can easily tell when you're playing with favorites, and if you reward or play more with other pets, your dog might notice it and feel uncomfortable. As they can't say how they feel, they will scratch, yawn or lick their mouths.

They smell fear. Let's say you are faced with your worst fear. Would you get scared and run away or just face it? Before choosing how to deal with it, you should remember one thing. 4. Research shows that dogs often sense their master's response in dangerous situations. If you fear something and choose to back away, chances are that your pet is going to do the same thing.

They're watching you. We are all raised as responsible individuals who are taught to respect elders, obey the law and help out people in need from time to time. 5. But if you have a dog at home, it is time to be serious about them. Dogs like generous people. So just be careful around your pet; it may judge you on how you behave with others.

A. They sense health problems.

B. They understand when ignored.

C. They know when no one's looking at them.

D. You would be setting an example to your pet.

E. Every time you feel sad, your dog just knows it.

F. But dogs are able to sense everything around them.

G. However, not all of us take these three things seriously.

Dogs were living as companions to the early settlers of North America over 10,000 years ago.

The oldest domestic dogs in the Americas were thought to be around 9500 years old. Angela Perri of Durham University, UK, and her colleagues have carried out fresh radiocarbon dating on the two dog skeletons that gave this date, discovered in the prehistoric Koster site in Illinois, and found they were even older: around 10,100 years old.

A third dog from another Illinois site called Stilwell II was older still，at 10,190 years old. That makes it the oldest known domesticated dog in the Americas.

The team concluded that all three dogs were domesticated as their skeletons were complete and unskinned, and so hadn’t been butchered for food. They had also been carefolly buried, evidence they were valued by their owners. The Stilwell II dog, which probably resembled a small English settler, was under what seemed to be the floor of a living area.

It is unclear why it took so long for tame dogs to arrive in the Americas, given that they were domesticated at least 14,000 years ago in Eurasia. By this time, people were already moving into North America from Siberia; there is evidence some reached Chile 18,500 years ago. Geneticists have found signs of at least three waves of migration over the following millennia. There is no evidence that domestic dogs accompanied them.

“We don’t know if dogs were part of the first waves of immigration to the Americas” says Luc Janssens of Ghent University in Belgium. “It could be so, but no archaeological bones have yet been found.”

It is “overwhelmingly probable” that some of the early settlers did bring dogs to the Americas, but they may not have had “the time or the spiritual compulsion to bury them’％ says Pat Shipman of Pennsylvania State University.

1.How old is the oldest known domestic dog in the Americas?

A. About 9500 years.　　 B. About 10,100 years.

C. 10,190 years.　　 D. 18,500 years.

2.The underlined word “butchered” in the fourth paragraph could be replaced by .

A. killed　　 B. bought

C. trained　　 D. raised

3.What is the attitude towards when tame dogs arrived in the Americas in the last three paragraphs?

A. Undoubted.　　 B. Unsure.

C. Indifferent.　　 D. Unconfident.

4.What is the main topic of this passage?

A. The earliest domestic dog in the Americas.

B. The first dog arriving in the Americas.

C. How dogs were domesticated in the Americas.

D. When the oldest dog was found in the Americas.

Anger is good for you, as long as you control it, according to new psychology research. A new study from Carnegie Mellon University shows anger may help people reduce the negative impacts of stress and help you become healthier.

“Here getting emotional is not bad for you if you look at the case of anger,” said Jennifer Lerner of Carnegie Mellon. “The more people display anger, the lower their stress responses.”

Lerner studied 92 UCLA students by asking them to count back from 6,200. They must say out loud every thirteenth number. Researchers disturbed them by asking them to count faster or ask them other questions. If they made any mistakes, they had to restart from the very beginning. Many students felt depressed about making so many mistakes or got angry.

Lerner used a hidden video camera and recorded all their facial expressions during the test. The researchers describe their reactions as fear, anger and disgust.

Other researchers recorded the students’ blood pressure, pulse and production of a high-stress hormone（荷尔蒙）called cortisol. People whose faces showed more fear during the experiment had higher blood pressure and higher levels of the hormone. Both can have lasting effects such as diabetes（糖尿病）, heart disease, depression and extra weight gain.

When people feel fear, negative impacts increase, but when they get angry, those negatives go down, according to the study.

“Having that sense of anger leads people to actually feel some power in what otherwise is a maddening（令人发狂的）situation,” Lerner said.

Lerner previously studied Americans’ emotional response to the 9/11 terrorist attacks two months after the incident. She found people who reacted with anger were more optimistic. These people are healthier compared with those who were frightened during the event. So in maddening situations, anger is not a bad thing to have. It’s a healthier response than fear.

1.What is the story mainly about?

2.Which statement will Jennifer Lerner agree with?

3. What does the underlined word “both” refer to according to the passage?

4.In what ways can anger be beneficial to people?

5.The researchers irritated（激怒）the students by __________.

高三英语阅读理解中等难度题查看答案及解析

According to new health guidelines, even a minute or two of physical exercise is better than nothing: just walking upstairs and down again, before continuing your otherwise entirely sofa-based afternoon of crisps and television, makes for a healthier life than if you hadn' t bothered. The previous recommendation was for a 10-minute minimum, but for years’ the general direction of research has been toward the conclusion that there is no minimum at all. This doesn51 just go for exercise^ either. Five minutes in nature can boost your mental health; and while one daily serving of vegetables may be too few, it's definitely preferable to zero. If you are wondering whether or not some tiny but healthful activity is worth it, the answer^ almost always, is yes.

It' s a little strange　 actually, that this is even a topic of debate. Of course anything is better than nothing. For one thing, it's a good start for building habits. For another, tiny actions are valuable in themselves. Human bodies aren't digital devices, and health generally isn't a matter of reaching fixed thresholds （门槛）；what is good for the organism in large quantities is usually good in smaller ones, too.

The real reason for the debate is not that the facts are in dispute （争议）.It's that information is dangerous. When public bodies recommend^ say, a 10-minute minimum, it's because they worry that if they don't, people who might otherwise have exercised for 10 minutes will stop after two.

Even this column risks making things worse. If you had truly been planning to spend all day on the sofa, perhaps I have inspired you to take a five-minute walk; but if there is a chance that you would have gone to the gym for an hour, reading these words might persuade you to settle for the stroll （散步）instead.

Ideally, we would stop thinking about healthy behaviours in terms of minimums: within reason, you should be doing as much exercise as you can, not as little as you can get away with—while remembering that nothing is too minor to be not worth the bother. This is a sensible approach to much of life, I would say, from being a good friend or paying attention to your kids, to saving money or reducing your environmental impact. However much you do9 it will never be enough. But that is not a reason to do nothing—on the contrary^ it' s a reason to do something.

1.Tiny healthy actions are worthwhile because　 •

A.they contribute to good habits and health

B.they provide abundant choices for fitness

C.they add a new dimension to people, s lives

D.they are easily conducted in people5 s daily lives

2.Why don public bodies recommend a minimum time for exercise?

A.People have their own concept of time.

B.It contradicts with new health guidelines.

C.There is a lack of scientific research on it.

D.People may misinterpret its real intentions.

3.What does the writer want to stress in the passage?

A.Life lies in movement.

B.All roads lead to Rome.

C.Actions speak louder than words.

D.Anything is better than nothing.
