每個(gè)國(guó)家都有各自的文化習(xí)慣，而這種文化上的差異往往會(huì)引起一定的誤會(huì)，不過(guò)只要熟悉對(duì)方的風(fēng)俗習(xí)慣做到入鄉(xiāng)隨俗，一切就OK啦！

When my family moved to America in 2010 from a small village in Guangdong, China, we brought not only our luggage, but also our village rules, customs and culture.One of the rules is that young people should always respect(尊敬)elders.Unluckily, this rule led to my very first embarrassment in the United States.I had a part-time job as a waiter in a Chinese restaurant.One time, when I was serving food to a middle-aged couple, the wife asked me how the food could be served so quickly.I told her that I had made sure they got their food quickly because I always respect the elderly.As soon as I said that, her face showed great displeasure.My manager, who happened to hear what I said, took me aside and gave me a long lecture about how sensitive(敏感)Americans are and how they dislike the description “old”.I then walked back to the table and apologized to the wife.After the couple heard my reason, they understood that the problem was caused by cultural differences, so they laughed and were no longer angry.In my village in China, people are proud of being old.Not so many people live to be seventy or eighty, and people who reach such an age have the most knowledge and experience.Young people always respect older people because they know they can learn from their rich experience.However, in the United States, people think “growing old” is a problem since “old” shows that a person is going to retire or that the body is not working well.Here many people try to keep themselves away from growing old by doing exercises or jogging, and women put on makeup, hoping to look young.When I told the couple in the restaurant that I respect the elderly, they got angry because this caused them to feel they had failed to stay young.I had told them something they didn’t want to hear.After that, I changed the way I had been with older people.It is not that I don’t respect them any more;I still respect them, but now I don’t show my feelings through words.By Jack 根據(jù)以上短文內(nèi)容，然后從每題所給的四個(gè)選項(xiàng)中選擇最佳選項(xiàng)。

Linda Evans was my best friend—like the sister I never had.We did everything together: piano lessons, movies, swimming, horseback riding.When I was 13, my family moved away.Linda and I kept in touch through letters, and we saw each other on special time—like my wedding(婚禮)and Linda’s.Soon we were busy with children and moving to new homes, and we wrote less often.One day a card that I sent came back, stamped “Address(地址)Unknown.” I had no idea how to find Linda.Over the years, I missed Linda very much.I wanted to share(分享)happiness of my children and then grandchildren.And I needed to share my sadness when my brother and then mother died.There was an empty place in my heart that only a friend like Linda could fill.One day I was reading a newspaper when I noticed a photo of a young woman who looked very much like Linda and whose last name was Wagman — Linda’s married name.“There must be thousands of Wagmans,” I thought, but J still wrote to her.She called as soon as she got my letter.“Mrs Tobin!” she said excitedly, “Linda Evans Wagman is my mother.”

Minutes later I heard a voice that I knew very much, even after 40 years, laughed and cried and caught up on each other’s lives.Now the empty place in my heart is filled.And there’s one thing that Linda and I know for sure: We won’t lose each other again!根據(jù)以上短文內(nèi)容，然后從每題所給的四個(gè)選項(xiàng)中選擇最佳選項(xiàng)。1.The writer went to piano lessons with Linda Evans _______.A.at the age of 13 B.before she got married C.after they moved to new homes D.before the writer’s family moved away 2.They didn’t often write to each other because they _______.A.got married B.had little time to do so C.didn’t like writing letters D.could see each other on special time 3.There was an empty place in the writer’s heart because she _______.A.was in trouble B.didn’t know Linda’s address C.received the card that she sent D.didn’t have a friend like Linda to share her happiness or sadness 4.The writer was happy when she _______.A.read the newspaper B.heard Linda’s voice on the phone C.met a young woman who looked a lot like Linda D.wrote to the woman whose last name was Wagman 5.They haven’t kept in touch _______.A.for about 40 years B.for about 27 years 3

A man went to see his doctor one day, because he was suffering from pains in his stomach.After the doctor had examined him carefully, he said to him, “Well, there’s nothing really wrong with you, I’m glad to say.Your only trouble is that you worry too much.Do you know, I had a man with the same trouble as you here a few weeks ago, and I gave him the same advice as I am going to give you.He was worried because he couldn’t pay his tailor’s bills.I told him not to worry about the bills any more.He took my advice and when he came to see me again two days ago, he told me that he now felt quite all right again.” “Yes, I know all about that,” answered the patient sadly.“You see, I’m that man’s tailor!”

慈母手中線，游子身上衣，誰(shuí)言寸草心，報(bào)得三春暉。母愛是世界上最偉大、最無(wú)私的，她寬容大度，她不求回報(bào)，她為子女付出很多很多??

I’ve loved my mother’s desk since I was just tall enough to see above the top of it as mother sat doing letters.Standing by her chair, looking at the ink bottle, pens, and white paper, I decided that the act of writing must be the more wonderful thing in the world.Years later, during her final illness, mother kept different things for my sister and brother.“But the desk,” she’d said again, “it’s for Elizabeth.”

I never saw her angry, never saw her cry.I knew she loved me;she showed it in action.But as a young girl, I wanted heart-to-heart talks between mother and daughter.They never happened.And a gulf opened between us.I was “too emotional(易動(dòng)感情的)”.But she lived “on the surface(表面)”.As years passed I had my own family.I loved my mother and thanked her for our happy family.I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive(原諒)me.I posted the letter and waited for her answer.None came.My hope turned to disappointment(失望), then little interest and, finally, peace— it seemed that nothing happened.I couldn’t be sure that the letter had even got to mother.I only knew that I had written it, and I could stop trying to make her into someone she was not.4

Now the present of her desk told, as she’d never been able to, that she was pleased that writing was my chosen work.I cleaned the desk carefully and found some papers inside —a photo of my father and a one-page letter, folded(折疊)and refolded many times.Give me an answer, my letter asks, in any way you choose.Mother, you always chose the act that speaks louder than words.根據(jù)短文內(nèi)容，選擇最佳答案。

1.The writer began to love her mother’s desk ______.A.after Mother died

B.before she became a writer C.when she was a child D.when Mother gave it to her 2.The passage shows that ______.A.mother was cold on the surface but kind in her heart to her daughter B.mother was too serious about everything her daughter had done C.mother cared much about her daughter in words D.mother wrote to her daughter in careful words 3.The word “gulf” in the passage means ______.A.deep understanding between the old and the young B.different ideas between the mother and the daughter C.free talks between mother and daughter D.part of the sea going far in land 4.What did mother do with her daughter’s letter asking forgiveness? A.She had never received the letter.B.For years, she often talked about the letter.C.She didn’t forgive her daughter at all in all her life.D.She read the letter again and again till she died.5.What’s the best title of the passage?

A.My letter to Mother B.Mother and Children C.My mother’s Desk D.Talks between Mother and Me

六、中考英語(yǔ)閱讀理解·顧此失彼

許多年前，農(nóng)民為保護(hù)他們的雞而獵殺了很多老鷹。然而新的問(wèn)題來(lái)了，田里的田鼠猖狂了起來(lái)，結(jié)果農(nóng)民的莊稼大多給吃光了。這是怎么回事呢？看看下文你就知道了，但一定要記?。篒t is important for us to keep the balance of nature.Not many years ago, some farmers were worried because hawks were taking many of their chicken.The farmers didn’t know what to do.Finally they went to the country officials and asked for help.“Kill the hawks,” the officials said, “We will even pay for them,” so the farmers began to think of ways to kill the hawks.The farmers killed many hawks.They no longer had to worry about their chickens.But they now had a new worry.Field mice were eating up a lot of the farmers’ grain.How did this happen? Hawks eat not only chickens but also field mice.They eat more field mice than chickens.But the farmers didn’t know this.When they killed a lot of hawks, they changed the balance.When people move into a new place, they often destroy many wild plants.Often these plants are food for the animals.If the animals can’t find enough plants to eat, they will starve or have to leave the place.5

In one part of the USA, for example the deer there like to eat a certain kind of wild roses.The mountain lions there eat the deer.The number of deer, mountain lions and wild roses doesn’t change much if people leave things as they are.But people killed many mountain lions in order to protect the deer.Soon there were so many deer that they ate up all the wild roses.Then the deer began to eat the green leaves of young trees.These trees were important to the farmers.So the farmers thought of ways to protect their trees.Now the deer had nothing to eat, and many of them died.This was another lesson from nature.To keep the balance of nature is important for us to remember.根據(jù)以上短文內(nèi)容判斷正誤，正確的用“T”表示，錯(cuò)誤的用“F”表示。1.Finally the officials told the farmers to kill the hawks.2.Field mice eat not only chickens but also the farmers’ grain.3.When the animals can’t find enough plants to eat in a place, they will starve or have to leave.4.The number of animals changes much if people leave things as they are.5.It is important for us to keep the balance of nature.七、中考英語(yǔ)閱讀理解·幽默故事

Little Tommy was doing very badly in math.His parents had tried everything—tutors(家庭教師), cards, special learning centers—in short, everything they could think of.Finally they took Tommy to a catholic(天主教的)school.After the first day, little Tommy came home with a very serious look on his face.He didn’t kiss his mother hello.Instead, he went straight to his room and started studying.Books and papers were spread(鋪開)out all over the room and little Tommy was hard at work.His mother was surprised.She called him down to dinner and as soon as he finished eating, he went back to his room, without a word.In no time he was back hitting the books as hard as before.This went on for some time, day after day while the mother tried to understand what was happening.Finally, little Tommy brought home his report card.He quietly put it on the table and went up to his room and hit the books.His mom looked at it and to her surprise, little Tommy got an A in math.She could no longer hold her curiosity(好奇心).She went to his room and asked, “Son, what was it? Was it the nuns(修女)?”

Little Tommy looked at her and shook his head, “No.” “Well then,” she asked again.“WHAT was it?”

Little Tommy looked at her and said, “Well, on the first day of school, when I saw that man nailed(釘)to the plus sign(加號(hào)), I knew they weren’t joking.”

I worked for a short time as a cashier(出納員)at a restaurant a few months ago.I also helped to clean up the tables when it was very busy.One night, just before Christmas, I found a large black wallet on the floor near one of the tables.I guessed I should check it to find out who was the owner, but I was very busy at the time.And I imagined that if there was something valuable(有價(jià)值的)in the wallet, the owner would be back.Sure enough, an hour later a man came up to the counter and asked if anyone had found a wallet.I asked him to describe the lost wallet, and after he described it exactly, I gave him the wallet.He expressed his thanks when I handed it to him.He asked me if I had opened it, and when I told him “no”.At once he opened it and showed that it had nearly $ 800 in cash(現(xiàn)金).He took out a twenty-dollar bill and handed it to me and I was amazed at this.“A reward(酬勞)for your honesty,” he said and then turned and walked away.Thinking about it later, I began wondering whether I would have been honest if I had known what was in the wallet!I thought that if I had no way to find the owner and no one returned to get it, I might keep it.But it also came into my mind that I actually saved someone’s Christmas plans by finding and returning the wallet.The good feeling it gave me was worth more than anything could buy.根據(jù)以上短文內(nèi)容，然后從每題所給的四個(gè)選項(xiàng)中選擇最佳選項(xiàng)。1.Which of the following is true?

A friend of mine named Paul received an expensive car from his brother as a Christmas present.On Christmas Eve when Paul came out of his office, a street urchin(頑童)was walking around the shining car.“Is this your car, sir?” he asked.Paul answered, “Yes, my brother gave it to me for Christmas.” The boy was surprised.“You mean your brother gave it to you and it did cost you nothing? Sir, I wish?” He hesitated(猶豫).Paul thought of course he knew what the boy wanted, but what the boy said surprised him greatly.“I wish,” the boy went on, “that I could be a brother like that.” Paul looked at the boy in surprise, and then he said again, “Would you like to take a ride in my car?” “Oh yes, I’d love to,” the boy answered.After a short ride, the boy turned and with his eyes shining, said, “Sir, would you mind driving in front of my house?”

Paul smiled a little.He thought he knew what the boy wanted.He wanted to show his neighbors that he could ride home in a big car.But Paul was wrong again.“Will you stop where those two steps are?” the boy asked.He ran up to the steps.Then in a short while Paul heard him coming back, but he was not coming fast.He was carrying his little crippled(殘疾的)brother.He sat down on the step and pointed to the car.“There he is, Buddy, just like I told you upstairs.His brother gave it to him for Christmas and it didn’t cost him a cent.And some day I’m going to give you one just like it?then you can see for yourself all the nice things in the Christmas windows that I’ve been trying to tell you about.”
