Dogs may not know exactly what you are doing especially when you’re trying to figure out a square root or diagram a sentence. But according to a new study, dogs can understand what we’re thinking and feeling by reading our facial expressions and body language and following our eyes.

Researchers studied 29 dogs. The dogs were shown a movie where a woman looked directly at them and said “Hi dog!” Then, the woman looked at a flowerpot sitting next to her. The researchers found that when the woman looked at and spoke directly to a dog, the dog usually followed her eyes to the flowerpot. It proved that the dogs knew that the woman was thinking about the flowerpot.

“By following the eye movements of dogs, we were able to get a first-hand look at how their minds are actually working,” said Jozsef, the senior researcher.

Later in the movie, the woman said “Hi dogs” in a low voice and didn’t look at the dog before looking at the flowerpot. In that situation, the dogs didn’t seem to understand what the woman was thinking. There was no eye contact, and the woman didn’t appear to speak to the dogs directly.

That comes as no surprise to dog trainer Jones. “Dogs normally speak through nonverbal signals. It’s more natural to them,” she said. “If you’ve ever watched dogs at a dog park, you’ve seen it. Within 30 seconds they enter the park, much information has passed between the new dog and the ones already in the park. They’re exchanging looks, observing eyes and body posture. On the other hand, when you speak to a dog, they are learning a foreign language.”

Picking up your nonverbal signals seems more natural. So, if you were hoping that all this means your dog could help you solve your math problems, you’re probably out of luck. But he or she might be a lot more in tune with what you’re thinking than you previously thought.

1.How could the researchers find that the dogs understood the woman’s intention?

A.By speaking to them directly.

B.By reading their eye movements.

C.By following their facial expressions.

D.By asking the dog trainer questions.

2.According to the text, Jones finds that ______.

A.dogs usually speak through verbal signals

B.dogs learn a great deal more at a dog park

C.dogs can understand humans’ words easily

D.dogs speak through eyes and body language

3.It is implied in the text that dogs can read your emotions only if ______.

A.you manage to get their attention

B.you like making friends with them

C.you are familiar with their behavior

D.you can pick up their verbal signals

4.What does the underlined phrase “be in tune with” in the last paragraph mean?

A.refuse

B.approve

C.understand

D.love

1.B

2.D

3.A

4.C   

【解析】

Among the dead in South Asia’s tsunami were many tourists at Sri Lanka’s national wildlife park at Yala. But very few of the park’s animals — elephants, buffaloes, monkeys and wild cats — appear to have died. There are theories that animals can sense natural disasters and flee to safety.

First, it’s possible that the animals may have heard the quake before the tsunami hit. The underwater rupture likely produced sound waves known as infrasound or infrasonic sound. Humans can’t hear infrasound, but many animals including dogs, elephants, tigers and pigeons can.

A second early warning sign the animals might have sensed is ground vibration. The massive quake would have produced vibrational waves known as Rayleigh waves. These vibrations move through the ground like waves move on the surface of the ocean but faster. They travel at ten times the speed of sound. The Rayleigh waves would have reached SriLanka hours before the water hit. Mammals, birds, insects and spiders can sense Rayleigh waves. So the animals at Yale might have felt the Rayleigh waves and then run to higher ground.

But what about humans? While we can’t hear infrasound, we can feel it, although we don’t necessarily know we’re feeling it. We also experience Rayleigh waves by special sensors in our joints, which exist just for that purpose. Sadly, it seems we don’t pay attention to the information when we get it. Maybe we screen it out because there’s so much going on before our eyes and in our ears. Humans have a lot of things on our minds and usually that works out OK.

Notes:

tsunami  n. 海嘯

infrasound  n. 次聲

vibration  n. 振動,顫動

Choose the best answers according to the above:

Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit?

A. Because the animals were staying at a higher place in the park.

B. Because the animals were able to run much faster than human beings.

C. Because human beings cannot hear the infrasonic sound.

D. Because the animals might have picked up the danger signals and ran away.

Which of the statements about “Ravleigh waves” is true?

A. Rayleigh waves are massive vibrational waves that usually cause quakes or tsunamis.

B. Rayleigh waves move on the ocean surface at a speed ten times that of sound waves.

C. Rayleigh waves can be felt both by animals and human beings.

D. Rayleigh waves, just like infrasonic sound, can only be felt by animals.

When a tsunami hits, it is possible that ____.

A. we can’t feel the infrasound so we can’t be informed of the danger

B. we can feel Rayleigh waves as well as infrasound so we are able to escape the danger like animals

C. we were so busy with things on our minds that we feel neither infrasound nor Rayleigh waves

      D. we think nothing of the information of its coming even though we can also get it

What does the underlined word “that” in the last sentence refer to?

A. Screening out the information.

B. There being so much going on before our eyes and in our ears.

C. Having a lot of things on our minds.

D. Paying attention to the information.

Dog walkers provide a 20 to 60-minute daily walk for a client’s(客戶)dog, making sure the dog answers the call of nature and gets proper exercise. They often walk more than one dog at a time. Some walkers work for dog-walking services, especially when starting out. Others have their own businesses, and build by word of mouth and advertising. Dog walkers often work part-time, and some provide other services like pet sitting or transporting.
In N.Y.C., dog walkers usually earn about $25 an hour. If you work for a dog-walking business, you may earn less-if you are on your own dealing with several dogs at the same time, it may be more.
What do you have to do to be a dog walker?
First, have a real love of dogs, and have a good knowledge of how to get on with dogs. Try calling dog-walking services to find out about openings. If you’re on your own, you’ll need to network and market yourself. You might advertise your services in pet offices, grooming businesses, or neighborhood papers. You will need business cards and a mobile phone, and have good references and a clean background. You’ll also have to deal with taxes and insurance. You should be physically fit, friendly, neatly dressed and extremely dependable. Many dog walkers are bonded(被擔保的)and insured, and this is a definite selling point to clients.
Of course, you will be cleaning up dog waste! You will also be outside in all kinds of weather. You may have to deal with dogs that don’t like each other ,and difficult owners. It’s also an up and down kind of business-clients can come and go.
For pet lovers, spending the workday with dogs instead of navigating office politics is its own reward! You are your own boss-you can dress casually, your doggy clients will love you unconditionally, and you’ll get some great exercise!
71. By writing the passage the writer tries to         .
A. introduce you to a job           B. enrich your knowledge about pets
C. advertise for a business         D. tell you more about life in New York
72. The passage offers no information about how to         as a dog walker.
A. find a client                    B. train a dog
C. get prepared                     D. make more money

A. take up a weekend job            B. keep a good pet dog
C. make money in his daily spare time  D. be a part-time office worker
74. The last paragraph but one (beginning with “Of course”) is meant to tell you         .
A. what dog-walking is like         B. why dog-walking is worth trying

“Every week I reorganized them on their shelves so they could meet new friends,My books were HAPPY books.You could tell just by looking at them.Now they’re all back in the libraries,on the lower shelves,on the floors,at the mercy of all those runny-nosed kids I can hear them calling me.I need to rescue them.Excuse me.I have to go now.”
