At the beginning of the World Series of 1947, I experienced a completely new emotion, when the National Anthem was played．This time, I thought, it is being played for me, as much as for anyone else．This is organized major league baseball, and I am standing here with all the others; and everything that takes place includes me.
About a year later, I went to Atlanta, Georgia, to play in an exhibition game．On the field, for the first time in Atlanta, there were Negroes and whites．Other Negroes besides me．And I thought: What I have always believed has come to be.
And what is it that I have always believed? First, that imperfections are human．But that wherever human beings were given room to breathe and time to think, those imperfections would disappear, no matter how slowly．I do not believe that we have found or even approached perfection．That is not necessarily in the scheme of human events．Handicaps, stumbling blocks, prejudices — all of these are imperfect．Yet, they have to be dealt with because they are in the scheme of human events.
Whatever obstacles I found made me fight all the harder．But it would have been impossible for me to fight at all, except that I was sustained by the personal and deep-rooted belief that my fight had a chance．It had a chance because it took place in a free society．Not once was I forced to face and fight an immovable object．Not once was the situation so cast-iron rigid that I had no chance at all．Free minds and human hearts were at work all around me; and so there was the probability of improvement．I look at my children now, and know that I must still prepare them to meet obstacles and prejudices.
But I can tell them, too, that they will never face some of these prejudices because other people have gone before them．And to myself I can say that, because progress is unalterable, many of today's dogmas （教条）will have vanished by the time they grow into adults．I can say to my children: There is a chance for you．No guarantee, but a chance．And this chance has come to be, because there is nothing static with free people．There is no Middle Ages logic so strong that it can stop the human tide from flowing forward．I do not believe that every person, in every walk of life, can succeed in spite of any handicap．That would be perfection．But I do believe — and with every fiber in me — that what I was able to attain came to be because we put behind us （no matter how slowly） the dogmas of the past: to discover the truth of today; and perhaps find the greatness of tomorrow.
I believe in the human race．I believe in the warm heart．I believe in man's honesty．I believe in the goodness of a free society．And I believe that the society can remain good only as long as we are willing to fight for it — and to fight against whatever imperfections may exist．My fight was against the barriers that kept Negroes out of baseball．This was the area where I found imperfection, and where I was best able to fight．And I fought because I knew it was not doomed to be a losing fight．It couldn't be a losing fight-not when it took place in a free society．And in the largest sense, I believe that what I did was done for me — that it was my faith in God that sustained me in my fight．And that what was done for me must and will be done for others.Why did the author say he had experienced a completely new emotion?

When, after a year of being alone on his island, Robinson Crusoe sees a footprint in the sand, the reader of Robinson Crusoe trembles. Will Crusoe find another human being to end his loneliness? Is the footprint the sign of an enemy? Since 1719, when Daniel Defoe wrote Robinson Crusoe, thousands of people who enjoy English novels have thrilled to this great adventure story. But few know how the story came to be written. Robinson Crusoe was the first English novel. Its birth brought together the misadventures of a Scotch “failure” and the untapped imagination of an aging English scribbler.
Near the end of the Seventeenth Century, the hot-tempered Alexander Selkirk was charged with bad conduct while in church. Rather than face this charge, he ran away to sea. Several years later, Selkirk found himself on the ship of an English privateer. The privateer was preying on Spanish shipping. But Selkirk quarreled bitterly with the Captain. So, when the ship came to the island of Juan Femandez in the South Seas, Selkirk asked to be put ashore. When he saw that there were no people on the island, he begged to be taken back on board. But the Captain refused—Selkirk had gone too far. Over four years later, Selkirk was rescued by another ship.
When Selkirk got back to England, the story of his life on the island fired the imagination of Daniel Defoe. Defoe had been earning a living by his pen since he was thirty. He was amazingly hard-working. He wrote a whole newspaper three times a week. He also made part of his living from politics. He supported both political parties. He told each party that it had his sole support.

I’m afraid to grow old—we’re all afraid. In fact, the fear of growing old is so great that every aged person is an insult and a threat to the society. They remind us of our own death, that our body won’t always remain smooth and responsive, but will someday betray(背叛) us by aging. The ideal way to age would be to grow slowly invisible, gradually disappearing, without causing worry or discomfort to the young. In some ways that does happen. Sitting in a small park across from a nursing home one day, I noticed that the young mothers and their children gathered on one side, and the old people from the home on the other.
Whenever a youngster would run over to the “wrong” side, chasing a ball or just trying to cover all the available space, the old people would lean forward and smile. But before any communication could be established, the mother would come over, murmuring embarrassed apologies, and take her child back to the “young” side.
Now, it seemed to me that the children didn’t feel any particular fear and the old people didn’t seem to be threatened by the children. The division of space was drawn by the mothers. And the mothers never looked at the old people who lined the other side of the park. These well-dressed young women had a way of sliding their eyes over, around, through the old people; they never looked at them directly. The old people may as well have been invisible; they offended the aesthetic eye of the mothers.
My early experiences were somewhat different; since I grew up in a small town, my children had more of a nineteenth-century flavor. I knew a lot of old people, and considered some of them friends.People are afraid of growing old because it is usually associated with ______.
| A．insult | B．threat | C．death | D．betrayal |

Inland waters may be grouped into two general classes: standing waters and flowing waters. As is often the case, the boundary between these two classes is not sharp and clear. A pond is an example of standing water. But most ponds are fed by springs or brooks and most have an outlet. Thus some current of changing water flows through them. On the other hand, a river is an example of flowing water. In some places, however, a river may have such a slow current that it is very difficult to detect.
Standing inland waters differ in size, in age, and in many abiotic environmental characteristics. They range in size from roadside puddles to the Caspian Sea. Puddles may last for only a few days or weeks; ponds, for a few hundred to a thousand years. In general, lakes are older, though the waters of some tropical “lakes” disappear completely during each dry season. Standing waters vary from very shallow to very deep, from clear to muddy, from fresh to salty.
In flowing waters we roughly distinguish between brooks, creeks, and rivers. The size and age of flowing waters are unimportant. Speed of flow, clearness, oxygen content, and other chemical characteristics are used by scientists in studying flowing-water ecosystems.According to the passage, which of the following characteristics of flowing waters is unimportant?
| A．Clarity. | B．Size. | C．Speed of flow. | D．Oxygen content. |
The word “abiotic” in paragraph 2 can best be replaced by ______.
| A．nonliving | B．living | C．coastal | D．inland |
Which of the following statements is true?
| A．Usually the water in a river flows into a pond. |
| B．Scientists only study flowing-water ecosystems. |
| C．Usually ponds last much longer than puddles. |
| D．The Caspian Sea is considered as an example of flowing water. |
From this passage we may know that the distinction between standing waters and flowing waters ______.
| A．depends on how people name the waters |
| B．is clear |
| C．depends on the seasons |
| D．is hard to make |
This passage mainly tells us that ______.
| A．there are two major classes of inland waters |

During the 1800s, African Americans worked long days in the fields of the American South．To ease their labor, they sang "field hollers" that they had brought from Africa．One person sang a line．Then a group of workers repeated it．The songs' words told of the hardships that people suffered．African Americans sang "shout spirituals", or joyous religious songs．They clapped their hands and stomped their feet to the music．
After the Civil War, the music changed dramatically．African American music, from ballads to church music, took new forms．It also adapted dance music, called "jump-ups"．which had great rhythm． Banjos became popular．A blues singer usually played a call and response with the banjo．By the early 1900s, the guitar had replaced the banjo as the main blues instrument．
Northern Mississippi - called the Delta - was the center of the blues tradition．By the 1920s, the Delta had many clubs, so-called juke joints．African Americans listened and danced to music in these clubs．Some of the greatest blues men and women performed there．
Blues have a soulful sound that is easy to recognize．The musical notes are often "bent"．That is, they are changed slightly to give a song more strength．Whatever their origin, these bent notes most often define the blues．
Lyrics are the words of a song．Blues lyrics describe everyday life．The lyrics, often about relationships between men and women, are often very intense and personal．They tell about sorrow and overwork．They tell about finding or losing love, having money or being broke, being happy or sad and lonely．The lyrics may use humor to describe life's trials and joys．They almost always use the rhythms of everyday speech．A typical blues stanza, or group of lyrics, has three lines．The second line repeats the first line．The third line has different words．
By the 1940s, large numbers of African Americans had left the Delta and moved north to work． Many settled in Chicago．There, a new kind of "electric", or "Chicago" blues began．Many of its themes were the same, but these blues had "wailing" electric guitars and harmonicas．The music had a steady, strong drumbeat．The loud, driving Chicago blues was excellent dance music．Chicago blues led to the birth of a new music style-rock and roll．The "field holler" is a kind of music that came from ___．
| A．the American South． | B．Africa． |
| C．Chicago． | D．Asia． |
"Shout spirituals" and "field hollers" are similar in that both_____．
| A．used banjos． | B．were sung in church． |
| C．included call and response singing． | D．expressed sadness． |
A typical blues Stanza is made up of____．
| A．three lines． | B．a harmonica． |
| C．a driving beat． | D．four lines． |
One can conclude from the passage that the blues ___．
| A．would have widespread without the juke joints of the Mississippi． |
| B．served as a form of communication and self-expression． |
| C．was successful only in the American South． |
| D．there were only greatest blues man performed in these clubs． |

| B．they liked the Chicago blues． |
| C．there were more jobs there． |
| D．they wanted to create a new music style． |
Cloud seeding is a method of artificially causing clouds to produce precipitation （降水） in the form of rain or snow．Cloud seeding has also been used in attempts to modify the severity of hail storms and hurricanes．The effectiveness of cloud seeding remains controversial （有争议的）．but it continues to be used in some regions to try to increase rainfall for agriculture and to build snow packs for water supplies and power production．
Cloud seeding was developed by American scientists Irving Langmuir and Vincent Joseph Schaefer during and after World War II．Their work began as an effort to learn more about the buildup of ice on airplane wings, and eventually led them to attempt to create rainfall by releasing several pounds of crushed frozen carbon dioxide into a cloud from an airplane．In this form, the carbon dioxide is called dry ice．On November 13, 1946, the technique appeared to produce snow directly under the cloud; the snow then turned to rain as it fell to the ground．
For their experiment, Langmuir and Schaefer selected a supercooled cloud, one in which the water droplets remain liquid in subfreezing temperatures．Their theory was that small grains of dry ice falling through the cloud would cause tiny droplets of water vapor in the cloud to freeze into crystals that attracted more water vapor．Their theory proved to be correct and eventually the crystals became heavy enough to fall from the cloud as snow．As the snow reached the warmer temperatures closer to the ground, it melted and became rain．
Another scientist, Bernard Vonnegut, produced a method of cloud seeding using silver iodide （碘化银）．He used particles of silver iodide because its crystal structure resembled that of ice in clouds．Silver
iodide also had practical advantages over frozen carbon dioxide It could be stored at room temperature
and did not require an airplane as a delivery mechanism．Instead, silver iodide crystals could be fired by
cannons （大炮） high into the air, where wind carried them into the clouds．According to the text, Langmuir and Schaefer had intended to deal with__
A．how to freeze carbon dioxide
B．how to remove ice on plane wings
C．how to make weather forecast for the war
D how to hide planes in clouds at warWhat is the CORRECT order of the course for cloud seeding with dry ice?
a．snow becoming rain in wanner temperatures b．crystals attracting more water vapor
c．crystals falling in the form of snow d．crystals becoming very heavy
e．freezing tiny droplets of water vapor into crystals
f．putting small grains of dry ice in the cloud
| A．a-c-f-d-b-e | B．b-f-e-a-c-d |
| C．f-e-b-d-c-a | D．e-a-d-c-b-f |
Bernard chose silver iodide as a method of cloud seeding because___．
| A．it is much cheaper than dry ice | B．it can be stored at any rooms |
| C．it can be sent into clouds by wind | D．it is similar |
The best title for the passage may be "____"．
| A．Cloud Seeding |
| B．Artificial Raining |
| C．Weather Changing |
| D．Cloud Gathering |
How many methods of cloud seeding are mentioned in the passage?
| A．three | B．two | C．one | D．four |
