Have you ever wondered when dogs first became “man’s best friend” and the world’s favourite pet? If you have then you’re not alone. When and where dogs first began living side-side with humans are questions that have stirred hot debate among scientists. There are a few hard facts that all agree on. These include that dogs were once wolves and they were the first animal to be domesticated(驯养) by humans. They came into lives some 15000 years ago, before the dawn of agriculture.

Beyond that, there is little agreement. The earliest bones found that are unquestionable dogs and not wolves date from 14,000 years ago. However, 30,000-year-old skulls have been discovered in France and Belgium that are not pure wolf and some scientists think could be dogs.

With such puzzling evidence, many scientists are now turning to DNA to find out when and where dogs were first domesticated. In one research project, tens of thousands of blood samples have been taken from street dogs around the world. The plan is to compare them with those of wolves. It’s even possible to analyse DNA from ancient bones. Tiny pieces of the 30,000-year-old skulls mentioned earlier are currently being studied, and another DNA study has already shown that ancient dogs preserved in the Alaskan ice-fields evolved from Asian wolves, not American ones.

Indeed, the ancient DNA may turn out to be more informative than the DNA of living dogs. Because dogs have accompanied humans around the world for thousands of years, their current distribution may tell us very little of their origins. This is why different groups of scientists believe that dogs variously originated in eastern Asia, Mongolia, Siberia, Europe or Africa.

But why were the animals domesticated in the first place? The most recent theory is that dogs domesticated themselves, initially living in and around our ancient villages to eat any food thrown out. Today, this is a way of life still shared by three -quarters of a billion unowned dogs worldwide.

1. Which is the only statement generally agreed on by scientists studying dogs?

A. They originally were used as farm animal

B. They evolved from wolves found in Europe

C. They helped the development of agriculture

D. They were the first animal to be kept as pets

2. Why does the writer first mention the 30,000-year-old animals skulls?

A. To show that dogs were much larger in the past

B. To prove that dogs developed from Asian wolves

C. To suggest that dogs may have evolved much earlier

D. To argue that dogs were first kept in France and Belgium

3. How did scientists determine the origins of the ancient dogs found in Alaska?

A. By examine the animals’ DNA

B. By analyzing the age of their bones

C. By studying the shape of their skulls

D. By comparing them with modern dogs

4. Why did dogs start living with humans?

A. Because they were attracted by food

B. Because they were trapped by humans

C. Because they couldn’t survive in the wild

D. Because they were trained to protect villages

Have you ever wondered how the trainers at Sea World get the 19,000-pound whale to jump 22 feet out of water and perform tricks? They get that whale to go over a rope farther out of the water than most of us can imagine. 1..

So how do the trainers at Sea World do it? The first thing they do is reinforce(强化) the behavior that they want repeated --- in this case, to get the whale to go over the rope.2., in a position where the whale can’t help but do what’s expected of it. Every time the whale goes over the rope, it’s given positive reinforcement and gets fed with fish. But what happened when the whale goes under the rope? Nothing — no criticism, no warning and no feedback. 3..

Positive reinforcement is the key of that simple principle that produces such splendid results. And as the whale begins to go over the rope more often than under, the trainers begin to raise the rope. It must be raised slowly enough so that the whale doesn’t starve.

4.. Make a big deal out of the good and little stuff that we want consistently. Secondly, under-criticize. People know they need help when they mess up. 5., people will not forget the event and usually will not repeat it.

So we need to set up the circumstances so that people can’t fail. Over-celebrate, under-criticize…and know how far to raise the rope.

A. This is a great challenge

B. And the whale stays right where it is

C. If we figure out a way to motivate the whale

D. They start with the rope below the surface of the water

E. If we under-criticize, punish and discipline less than expected

F. Whales are taught that their negative behavior won’t be acknowledged

G. The simple lesson to be learned from the whale trainers is to over-celebrate

Have you ever thought that your life will be perfect if something in your outside world changes? You may say, “I will live happily if I find my soul mate.” You may say, “If the perfect job comes along, I will get satisfaction. My problem is that my boss is stupid.” Or you may say, “If I have a child, I will know what it is like to be loved.” The problem is that it is not the outside world that prevents you from experiencing peace, love and joy. Instead, it is your own internal (内部的) patterns that get in your way.

To prove this point, at my weekend programs, I had my students look at a flower on my table. Then I asked them to share their experiences. Some showed a state of complete joy because staring at the flower reminded them of their wedding or a great trip with their lovers. Others said the flower made them angry because it reminded them of a gift given by a former partner who turned against them. Some students even told me that the flower reminded them of their beloved grandmothers’ gardens with some shedding tears (流泪)of joy and others shedding tears of sadness. However, the flower was still just a flower.

Our internal patterns decide whether each moment is filled with peace, anger, joy, love or sadness. When you don’t realize that it is your own internal state that is creating your experience, you are likely to blame (责备)the external situations in your life. Most people aren’t taught that emotion is a choice. And they aren’t taught how to change those lower emotional patterns such as anger, anxiety, sadness and so on. Next time, when you meet something bad, please look at your internal state. When you accept that you are responsible for your own state, and find the courage to turn inward, you can step out of being a slave to what shows up in your external world.

1.Why does the author mention the examples in Paragraph 1 ?

A. To lead to the topic of this passage.

B. To complain about imperfect life.

C. To show common problems in life.

D. To encourage people to change the outside world.

2.How does the author prove his opinion?

A. By giving examples. B. By doing an experiment.

C. By telling a related story. D. By comparing other people’s opinions.

3.What does the author advise us to do in the last paragraph?

A. To step out of negative emotions.

B. To pay attention to our internal world.

C. To share our real emotions with others.

D. To use different methods to change bad emotions.

4.What does the author want to express through the passage?

A. Our external world matters a lot.

B. Our emotions can affect our health.

C. Our internal patterns truly decide our emotions.

D. Our experiences have a great influence on our emotions.

Have you ever been to the world’s smallest bookstore?

The World’s Smallest Bookstore, whose official name is just these three words, sits quietly about 100 miles northeast of Toronto.

The bookstore is about 10 feet by 10 feet，so it is easy to imagine how tiny it really is. The bookstore is open 24 hours a day. Inside the bookstore are various books, especially literary books and classic authors’ works. So if you are looking for something less popular, you may get a bit disappointed there.

Another special feature of this bookstore is that each book only costs three dollars. All the expenses are paid on the honor system, which means buyers should make a note of what they’ve bought and leave their money by themselves. So the tools of the trade in this bookstore are quite simple: pens, papers, light bulbs and a label-maker.

In order to catch passers-by’s attention, the billboards (广告牌) of the bookstore are several times bigger than the store itself. With these large eye-catchers, many people are willing to stop by and have a visit.
