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 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  average income among Arab-Americans is $39 580,which is higher than the US average. What would be the best title for the text? A) Arabs in America. B) The Two Arab Immigration Waves to America. C) Arab-Americans,Contributions to America. D) Arab-Americans,Education and Income.

(Question)
Nuclear power's danger to health, safety, and even life itself can be summed up in one word: radiation. Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.  At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.  This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents.        Radiation can hurt us. We must know the truth. What is the main idea of the passage? A) How to detect nuclear radiation. B) How radiation kill a man. C) The mystery about nuclear radiation. D) Serious damage caused by nuclear radiation.

Ques: I was in Houston a few weeks ago,and needed to be back home in Austin by midmorning the next day.Though I usually left in the evening,for some reason last time I had to choose to set off after midnight. I was on my way back to Austin when I realized I left an important file,and knew I had to return to get it.I took the first exit I could,but when I rounded the corner,an 18-wheeler was stopped dead in the exit lane.I swerved  to avoid it,and then I realized that there was something wrong with my car.So I pulled into a small parking lot and unsurprisingly found the area deserted at 3:15am.I've lived in urban areas most of my life.I'm fairly street-wise and don't become frightened easily,but I knew I was in a pretty tough neighborhood. There was no one in Houston to pick me up.I immediately locked the doors and picked up my phone to call a tow truck.Soon a young man knocked on my driver's side window and asked if he could help me.Judging from his appearance,he was far from a mad man,but I knew he was far more likely to rob than help me.So I lied to him.After a while,he asked again,but this time I politely refused and told him the tow truck was due any minute.He finally said,"Madam,you need help.A tow truck in Houston will arrive anywhere between 45minutes and approximately never (which I knew was true),and you aren't going anywhere until you change your flat tire." After considering thoroughly,I got out.He looked surprised,but got right to work.He changed the tire,returned the seat to its place and said,"Thank you for letting me help you.You gave me a chance when most people would never open the door to someone like me.Would it be okay if I gave you a hug?"When I recovered,I gave him a giant hug.I left with a new tire and a renewed faith in human nature. What's the matter with the author's car? A) It couldn't get started. B) Its oil ran out. C) It was out of control. D) Its tire blew out.
Ans: D


Ques: India is a developing country. It has thousands of years of tradition and culture. Different types of people live in India. In the old days the educational institutions   were called "ashramam" and teachers were "gurus". A guru was a respected person in society.  Now we are living in the technological world. Big changes are occurring in people's living. The influence of television, telephone, radio, computer, Internet and mobile phones is very strong in everyday life. But even today, teachers are role models for students. Teaching is still a respectable job. But there are great changes in the education system. One of the most obvious changes is that the influence of Western culture has increased. We are paying too much attention to doing business, just like the Western world. Teachers are likely to to be influenced by this too, but it is not good. Teachers are nation builders. The development of any country depends upon its education system. All types of development are possible through education. Another change has happened in the curriculum  . The curriculum connects the teacher and the student. While education is about learning, curriculum means the situations in which one learns. When we say that education deals with "what", then curriculum deals with "how" and "when". But at the moment, it is hard to say whether the curriculum is playing such a role. In modern society, teaching is considered as a job that   _  . A) is respected B) brings good luck C) is hopeless D) connects with the fashion
