[EX Q]: Article: Every immigrant leads a double life. Every immigrant has a double identity and a double vision, being suspended between an old and a new home, an old and new self. The very notion of a new home, of course, is in a sense as impossible as the notion of new parents. Parents are who they are; home is what it is. Yet home, like parentage, must be legitimized through love; otherwise, it is only a fact of geography or biology. Most immigrants to America found their love of their old homes betrayed: they did not really abandon their countries; their countries abandoned them. In America, they found the possibility of a new love, the chance to nurture new selves. Not uniformly, not without exceptions. Every generation has its Know-Nothing movement. Its understandable fear and hatred of alien invasion is as true today as it always was, but in spite of all this, the American attitude remains unique. Throughout history, exile has been a disaster; America turned it into a triumph and placed its immigrants in the center of a national epic. The epic is possible because America is an idea as much as it is a country. America has nothing to do with loyalty to a dynasty and very little to do with loyalty to particular place, but everything to do with loyalty to a set of principles. To immigrants, those principles are especially real because so often they were absent or violated in their native lands. It was no accident in the '60 and '70s, when alienation was in flower, that it often seemed to be "native" Americans who felt alienated, while aliens or the children of aliens upheld the native values. The immigrant's double vision results in a special, somewhat skewed perspective on America that can mislead but that can also find revelation in the things that to native Americans are obvious. Psychiatrist Robert Coles speaks of those "who straddle worlds and make of that very experience a new world." "Home is where you are happy." Sentimental, perhaps, and certainly not conventionally patriotic, but is appropriate for a country that wrote the pursuit of happiness into its founding document. That continues for the immigrant in America, and it never stops, but it comes to rest at a certain moment. The moment is hard to pin down, but it occurs perhaps when the immigrant's double life and double vision joint together toward a single state of mind. When the old life, the old home fade into a certain unreality: places one merely visits, in fact or in the mind, practicing the tourism of memory. It occurs when the immigrant learns his ultimate lesson: above all countries, America, if loved, returns love.
Answer: Immigrants have played an important role in America's history.
[EX A]: What's the result of American's unique attitude toward immigrants?

[EX Q]: Article: In the English language, there are many expressions using the word "mouth". For example, if you say bad things about a person, the person might protest and say "Do not bad mouth me." Sometimes, people say something to a friend or family member that they later regret because it hurts that person's feelings. Or they tell the person something they were not supposed to tell. The speaker might say :"I really put my foot in my mouth this time." If this should happen, the speaker might feel down in the mouth. In other words, he might feel sad for saying the wrong thing. Information is often spread through word of mouth. This is general communication between people, like friends talking to each other. "How did you hear about that new movie?" someone might ask. "Oh, by word of mouth." Sometimes when one person is speaking ,he says the same thing that his friend was going to say . When this happens, the friend might say "You took the words right out of my mouth." Sometimes a person has a bad or unpleasant experience with another person ,he might say "I had my heart in my mouth." Some people have lots of money because they were born into a very rich family. You might say such a person "was born with a silver spoon in his mouth ." This rich person is the opposite of a person who lives from hand to mouth. This person is very poor and only has enough money for the most important things in life. Parents might sometimes keep sweet food from a child ad punishment for saying bad things, For example , if a child says things she should not say to her parents , she might be described as a mouthy child. The parents might even tell the child to stop mouthing off.
Answer: Some expressions with the word "mouth".

[EX Q]: Article: Robby was 11 when his mother dropped him off for his first piano lesson. I prefer students begin at an earlier age. Robby insisted that it had always been his mother's dream to hear him play the piano, so I took him in as a student. Robby tried and tried while I listened and encouraged him and gave him more instructions . But he just did not have any inborn ability. I only saw his mother from a distance. She always waved and smiled but never came in. Then one day Robby stopped coming to our lessons. I thought about calling him but I guessed he had decided to try something else. _ . However, several weeks before the recital of my students, Robby came,telling me that he never stopped practicing and begged me to allow him to take part. I agreed but I made him perform last in the program, so I could always save his poor performance through my "curtain closer". I was surprised when he announced that he had chosen one piece of Mozart's. Never had I heard a piece of Mozart's played so well by someone at his age. When he finished, everyone was cheering. I ran up and put my arms around Robby in joy. "I've never heard you play like that, Robby! How'd you do it?" "Well, Miss Hondorf. Do you remember I told you my mom was sick? Actually she died this morning. She was born deaf so tonight was the first time she could hear me play. I wanted to make it special. I knew I could." That night, Robby was the teacher and I was the student. He taught me so many important things about life.
Answer: His mother was too sick to send him to the piano lessons.
