The Erie Canal was the first important national waterway built in the US. It crossed New York from Buffalo on Lake Erie Troy to Albany on the Hudson River. It joined the Great Lakes with the Atlantic Ocean. The canal served as a route over which industrial goods could flow into the west, and materials could pour into the east. The Erie Canal helped New York develop into the nation’s largest city.

The building of the canal was paid for entirely by the state of New York. It cost $ 7 143 789, but it soon gained its price many times over. Between 1825, when the canal was opened, and 1882, when toll charges(过运河费) were stopped, the state collected $121 461 891.

For a hundred years before the Erie was built, people had been talking about a canal which could join the Great Lakes and the Atlantic Ocean. The man who planned the Erie Canal and carried the plan through was De Witt Clinton. Those who were against the canal laughingly called it “Clinton’s Ditch(沟)”. Clinton talked and wrote about the canal and drew up plans for it. He and Governor Morris went to Washington in 1812 to ask for help for the canal, but they were unsuccessful.

Clinton became governor of New York in 1817, and shortly afterwards, on July 4, 1817, broke ground for the canal in Rome, N.Y. The first part of the canal was completed in 1820. As the canal grew, towns along its course developed fast. The length of the canal is 363 miles.

A. joined the Great Lakes together

B. crossed New York from north to south

C. played an important part in developing New York City

D. was the first waterway built in the US

3. Which of the following is true according to the passage?

A. The Erie Canal brought profits of over $114, 000, 000.

B. It’s 363 miles from the Great Lakes to the Atlantic Ocean.

C. The West was more advanced than the East when the canal was built.

D. Many other states helped New York built the canal.

4. Which of the following is true according to the passage?

A. Clinton broke ground for the canal at both ends.

B. Clinton started building the canal before he became governor.

C. All parts of the canal were completed at the same time.

D. Construction of the canal took eight years.

When I was growing up, I was embarrassed to be seen with my father. He was badly crippled (跛脚), and when we would walk together, his hand on my arm for balance, people would stare, I would be ashamed of the unwanted attention. If ever noticed or bothered, he never let on.

It was difficult to walk together—and because of that, we didn’t say much as we went along. But as we started out, he always said, “You set the pace. I will try to follow you.”

Our usual walk was to or from the subway, which was how he got to work. He went to work sick, and even in bad weather. He almost never missed a day, and would make it to the office even if others could not. It was a matter of pride for him.

When snow or ice was on the ground, it was impossible for him to walk, even with help... Such times my sister or I would pull him through the streets of Brooklyn, N.Y., on a child’s sleigh to the subway entrance. Once there, he would try to grasp handrail until he reached the lower steps that the warmer tunnel air kept ice free. In Manhattan the subway station was the basement of his office building, and he would not have to go outside again until we met him in Brooklyn on his way home.

When I think of it now, I am surprised at how much courage it must have taken for a grown man to suffer from shame and disability. And I am also surprised at how he did it—without bitterness or complaint.

He never talked about himself as an object of pity, not did he show any envy of the more fortunate or able. What he looked for in others was a “good heart”, and if he found one, the owner was good enough for him.

Now that I am older, I believe that is a proper standard by which to judge people, even though I still don’t know exactly what a “good heart” is. But I know the times I don’t have one myself.

He has been away for many years now, but I think of him often. I wonder if he sensed my reluctance to be seen with him during our walks. If he did, I am sorry I never told him how sorry I was, how unworthy I was, how I regretted it. I think of him when I complain about my troubles, when I am envious of another’s good fortune, when I don’t have a “good heart”.

How did the man treat his father when he was young?

A. He helped his father happily.

B. He never helped his father.

C. He helped his father, but not very happily.

D. He only helped his father take a walk after supper.

As a disabled man, his father____.

A. didn’t work very hard

B. didn’t go to work from time to time

C. hated those who had good fortune

D. was happy and satisfied, and never lost hope

What does the underlined word “reluctance” mean in the article? It means ____.

A. anger B. sadness C. happiness D. unwillingness

How did the father get to work usually?

A. By subway. B. By bus. C. By wheelchair. D. By bike.

Researchers at Sweden’s KTH Royal Institute of Technology say they have found further proof that the wolf ancestors of today’s dogs can be from southern East Asia -- findings that are contrary to theories placing the birth place in the Middle East. Dr Peter Savolainen, KTH researcher in evolutionary genetics, says a new study released Nov. 23 confirms that an Asian region south of the Yangtze River was the principal and probably the only region where wolves were domesticated（驯化）by humans.

Research data show clearly that dogs are descended from wolves, but there’s never been scientific agreement on where in the world the domestication process began. “Our analysis of Y-chromosomal（染色体）DNA now confirms that wolves were first domesticated in Asia south of Yangtze River -- we call it the ASY region -- in southern China or Southeast Asia,” Savolainen says.

The Y data supports previous evidence from mitochondrial（线粒体）DNA. “Taken together, the two studies provide very strong evidence that dogs appeared first in the ASY region,” Savolainen says.

Archaeological data and a genetic study recently published in Nature suggest that dogs originate from the Middle East. But Savolainen rejects that view. “Because none of these studies included samples from the ASY region, evidence from ASY has been overlooked,” he says.

Peter Savolainen and PhD student Mattias Oskarsson worked with Chinese colleagues to analyse DNA from male dogs around the world. Their study was published in the scientific journal Heredity.

Approximately half of the gene pool was universally shared everywhere in the world, while only the ASY region had the entire range of genetic diversity. “This shows that gene pools in all other regions of the world most probably originate from the ASY region,” Savolainen says.

“Our results confirm that Asia south of the Yangtze River was the most important -- and probably the only -- region for wolf domestication, and that a large number of wolves were domesticated,” says Savolainen.

In separate research published recently in Ecology and Evolution, Savolainen, PhD student Arman Ardalan and Iranian and Turkish scientists conducted a comprehensive study of mitochondrial DNA, with a particular focus on the Middle East. Because mitochondrial DNA is inherited only from the mother in most species, it is especially useful in studying evolutionary relationships.

“Since other studies have indicated that wolves were domesticated in the Middle East, we wanted to be sure nothing had been missed. We find no signs whatsoever that dogs originated there,” says Savolainen.

In their studies, the researchers also found minor genetic contributions from crossbreeding between dogs and wolves in other geographic regions, including the Middle East.

“This subsequent dog/wolf hybridisation（混合淡化技术）contributed only modestly to the dog gene pool,” Savolainen explains.

1.What does Dr. Peter Savolainen believe?

A. Dogs’ ancestors came from the Middle East.

B. Wolves were probably first trained to work for humans in the ASY region.

C. Analysis of Y-chromosomal DNA should be combined with mitochondrial DNA.

D. Samples of the previous studies are enough to support the conclusion.

2.We can learn from the passage that _______.

A．there is a universal agreement on the place of first domestication

B．data from ASY may highlight where dogs came from

C．Dr. Savolainen’s research mainly focuses on the Middle East

D．the dog/wolf hybridization makes up most of the dog gene pool

3.What is special about mitochondrial DNA?

A．It is only used in studying evolutionary relationships.

B．It alone can provide hard evidence for Savolainen’s research.

C．It is the most useful in finding out the birth place of dogs.

D．It comes from the mother of most animals and plants.

Dear John,

I'm sorry you didn't get the part you tried out for in that play. I know how much you wanted to be in the play. Now you feel that maybe acting isn't the right future for you. I think you're wrong. You're a good actor. Do you remember when you played Caesar in your summer theatre group's play? You were excellent . People clapped(鼓掌)every time you walked on stage（舞台). Even the other actors loved you.

All actors have to get used to being turned down for a job. It's part of an actor's life. Even famouse actors don't get every part they want. I think you should give acting another chance. You love it so much, and you're good at it. Don't be discouraged because you lose one part in the play. Wait a bit, and try for another one. After all , you can always give up some other time.

Love,

Jane
