For many in the United States,Arab-Americans are an invisible part of the population．Though Arab-Americans as a community have made great contributions to American society in fields from literature to politics to medicine,many Americans know very little about Americans of Arab backgrounds．
Arab history in the United States goes back to the late 1800’s when large numbers of Arab immigrants first began making their journey to a land known simply as“Amreeka”．
Historians generally describe Arab immigration to America in two waves．The first wave took place between 1860 and 1924．The first wave consisted of Lebanese and Syrian,and some Egyptian immigrants．These new immigrants,who were mostly Christian,came to America in search of better opportunities．Even the doomed Titanic,which set sail for America in 1912,had close to a hundred Arab passengers aboard．The majority of Arab-Americans today are descendents of the first wave of immigrants;they are the third or more generation Americans．
The second wave of immigrants followed after World War Ⅱ,caused by political unrest in the Middle East．This second wave of immigrants consists of mainly Arab Muslims（穆斯林）and continues to this day．
Arab-Americans make up 3 million of the population in the United States,according to demographers．And quite different from popular belief,64 percent of them are American-born．Eighty-two percent of Arab-Americans are US citizens．
Arab-Americans are beyond the national average in both education and income．Education is important among Arab-Americans;82 percent have high school diplomas,36 percent have bachelor’s degrees or higher,and 15 percent have graduate degrees．The-median（中位数的） average income among Arab-Americans is $39 580,which is higher than the US average．

Since my family were not going to be helpful, I decided I would look for one all by myself and not tell them about it till I’d got one.
I had seen an agency （中介机构） advertised in a local newspaper. I rushed out of the __36_ in search of it. I was wildly excited, and as _37_ as if I were going on the stage. Finding the 38 quite easily, I ran breathlessly through a door which said “Enter without knocking, if you please.”
The simple atmosphere of the office 39 me. The woman looked carefully at me for a while through her glasses, and then questioned me in a low voice. I answered softly. All of a sudden I started to feel rather 40 She wondered why I was looking for this sort of job I felt even more helpless when she told me that it would be 41 to get a job without experience I wondered whether I ought to leave, when the telephone on her desk rang. I heard her say:
“ 42 , I’ve got someone in the office at this very moment who might 43 .” She
wrote down a __44 , and held it out to me, saying: “Ring up this lady. She wants a cook immediately. In fact, you would have to start tomorrow by cooking a dinner for ten people.”
“Oh yes,” said I — 45 having cooked for more than four in my life. I 46 her again and again, and rushed out to the nearest telephone box. I collected my thoughts, took a deep breath, and rang the number. I said confidently that I was just what she was looking for.

查看习题详情和答案>>For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive to such messages.
Scientists are using powerful radio telescopes to listen to signals from about 1,000 stars, all within 100 light years of earth. In addition, they will scan the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal that stands out from the background noise.
Of the 200 billion stars in the Milky Way galaxy (银河星系), scientists find that 5% are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution (进化) of life. Based on the inhabitable (that can be lived in) planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.
However, many scientists wonder whether intelligent (智能的) life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.
Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is only about five billion years old, our galaxy is about 20 billion years old. In that time, some scientists think it is likely that civilization much more advanced than ours have developed. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.
According to the passage, how many planets in our galaxy might be inhabitable?
A. 5 billion． B. 10 billion. C. 15 billion. D. 200 billion
The first paragraph in this passage is mainly about ________ .
A. how scientists are looking for signs of life on other planets
B. why scientists are looking for signs of life on other planets
C. where scientists are looking for signs of life on other planets
D. when scientists are looking for signs of life on other planets
Which of these statements is True based on the information in the passage?
A. The earth is one of the oldest planets in our galaxy.
B. Most scientists believe that there is intelligent life on other planets.
C. Scientists don’t believe that there might be life on other planets.
D. Scientists are trying different ways to find signs of life on other planets.
