    In the late 1950s, a Russian geneticist called Dmitry K. Belyaev attempted to create a tame (驯化的) fox population. Through the work of a breeding programme at the Institute of Cytology and Genetics at Novosibirsk, in Russia, he sought to find the evolutionary pathway of tame animals. His test subjects were silver-black foxes, a melanistic (带黑色的) version of the red fox that had been bred in farms for the color of their fur.

    He selected the animals based on how they responded when their cage was opened. About 10% of the foxes displayed a weak “wild-response”, meaning they were docile around humans. Those that hid in the corner or made aggressive voices were left in the farm. Of those friendly foxes, 100 females and 30 males were chosen as the first generations of parents.

    When the young foxes were born, the researchers hand-fed them. They also attempted to touch or pet the foxes when they were two to two-and-a-half months old, for strictly measured periods at a time. If the young foxes continued to show aggressive response, even after significant human contact, they were thrown away from the population—meaning they were made into fur coats. In each selection, less than 10% of tame individuals were used as parents of the next generation.

    By the fourth generation, the scientists started to see dramatic changes. The young foxes were beginning to behave more like dogs. They wagged their tails and “eagerly” sought contact with humans. By 2005-2006, almost all the foxes were playful, friendly and behaving like domestic dogs. The foxes could “read” human hints and respond correctly to gestures or glances.

(1)、What do we know about Belyaev's breeding plan?

A、It explains how red foxes were bred. B、It focuses on how tame animals evolved. C、It explains why pet foxes became popular. D、It concentrates on why tame animals disappeared.
(2)、How did he choose his test foxes in the experiment?

A、By appearance. B、By color. C、By reaction. D、By flexibility.
(3)、What can be inferred from Paragraph 3?

A、Smart foxes were used for testing. B、The purpose of selection was unclear. C、Friendly foxes were kept on testing. D、The selection was not exact and thorough.
(4)、What is the distinguishing characteristic of the fourth generation foxes?

A、Behaving in a friendlier way. B、Eating plants. C、Having drooping ears. D、Having shortened legs.

    Two summers ago I was about to turn fifty and wanted to do something I'd never done before. My daughter Bailey thought skydiving (跳伞) would be perfect for me. I can promise you that of all the things I was thinking of doing, jumping out of an airplane never came close to making the list. As I age, I seem to have developed a growing fear of heights.

    After several requests from my daughter, I finally said yes and she looked almost shocked. I told a friend what we were doing, then we set off. We had a 3-hour drive to the jump site. We drove through some beautiful countryside, but then we passed a small cemetery(墓地). Then we passed another cemetery and another one. I asked if so many people died jumping out of airplanes in this area that they needed to keep building more cemeteries to bury all the bodies!

    As we squeezed into the little plane, I tightly held the right hand of my partner Ronnie. The short ride to altitude was cruel for me. As Bailey stepped to the door, she looked back at me and said “Dad, I'm sure you can do it!” I said yes as she rolled out. I immediately looked behind me and said “RONNIE I AM NOT FEELING GOOD!” He said, “It's going to be great. Besides, it's too late now anyway”, and we jumped out.

    The next five minutes were some of the most amazing of my life. It was so beautiful and peaceful—except for the parts where I was screaming. I prayed to God for the parachute (降落伞) to open, but mostly I told Him how thankful I was for my life and being with me through good and bad.

阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。

    Cities usually have a good reason for being where they are, like a nearby port or river. People settle in these places because they are easy to get to and naturally suited to communications and trade. New York City, for example, is near a large harbour at the mouth of the Hudson River. Over 300 years its population grew gradually from 800 people to 8 million. But not all cities develop slowly over a long period of time. Boom towns grow from nothing almost overnight. In 1896, Dawson, Canada, was unmapped wilderness(荒野). But gold was discovered there in 1897, and two years later, it was one of the largest cities in the West, with a population of 30,000.

    Dawson did not have any of the natural conveniences of cities like London or Paris. People went there for gold. They travelled over snow-covered mountains and sailed hundreds of miles up icy rivers. The path to Dawson was covered with thirty feet of wet snow that could fall without warming. An avalanche(雪崩) once closed the path, killing 63 people. For many who made it to Dawson, however, the rewards were worth the difficult trip. Of the first 20,000 people who dug for gold, 4,000 got rich. About 100 of these stayed rich men for the rest of their lives.

    But no matter how rich they were, Dawson was never comfortable. Necessities like food and wood were very expensive. But soon, the gold that Dawson depended on had all been found. The city was crowded with disappointed people with no interest in settling down, and when they heard there were new gold discoveries in Alaska, they left Dawson City as quickly as they had come. Today, people still come and go — to see where the Canadian gold rush happened. Tourism is now the chief industry of Dawson City — its present population is 762.

For many students who desire to move around but not far freely, one of the most common vehicles is the bicycle. For such a seemingly simple invention, its story is not that simple.

Most historians trace its origin back to 1817, when a German nobleman named Karl von Drais invented a wooden, two-wheeled machine that riders moved forward with their feet. His invention became popular in both England and France, where it eventually became known as the velocipede. Unfortunately, it was eventually banned as a danger to pedestrians and was rarely seen after the early 1820s.

Things were quiet for several decades until the bicycle development took off in the 1860s. An important milestone happened in Paris in 1863 when pedals (踏板) were added to the front axle (轴) . This occurred in Pierre Michaux's workshop but it's unclear whether he or his employee, Pierre Lallement, should be given credit for the innovation. Lallement moved to the United States, where he obtained a patent for "improvements in velocipedes" in 1866. These new machines proved to be popular, and the name "bicycle" had come into use by 1869. However, many people referred to them as "bone shakers", which described their clunky ride due to a heavy wooden frame and steel wheels.

In the 1870s, "high wheelers" or "penny-farthings" became popular. However, with a large front wheel and a much smaller rear wheel, they could be dangerous, if riders had to stop suddenly, as they would "take a header" when their momentum (动量) carried them over the front wheel onto their heads. Eventually, English inventor John Kemp Starley designed a "safety bicycle" with two same small wheels, a chain drive, and a set of gears. With tires added in and brake (刹车) systems bettered in the following decades, bicycle production had skyrocketed to over one million bicycles by 1899.

Mass production of bicycles increased their popularity greatly, since they became affordable for the average person. Over the course of the 20th century, manufacturers continued to improve the features and design of bicycles as new technologies appeared.
