阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
A
It's not easy to grow up. Actually, it's far from easy. Growing up can be a real “pain” for some of us. We are always doing things that someone else makes us do and aren't allowed to do all the things we like. Sometimes we feel trapped, sometimes we are fearful, and sometimes we just don't understand why we can't stay young forever. When we look back on all the hardships in life with a positive attitude, we realize that all of our growing pains actually turn into growing gains!
Throughout our lives we are going to face many challenges and pains, but we should never let these obstacles keep us from following our dreams. We must overcome every obstacle one small step at a time.
As a young girl my parents forced me to do so many things that I never liked. They made me learn to play the violin and then the piano. At that time I hated music, just because it was what they wanted me to do. But looking back now, I am so glad that my parents encouraged me to take music lessons. Music has enriched my life in so many ways. I realize that my parents and teachers were always pushing me along, not because they wanted me to suffer but because they wanted me to succeed in life. They've always wanted me to have a better life than they did themselves.
Every moment of our lives we are either living or dying, so live life to its fullest! We are all going to experience growing pains, but they are just small pains in life. They might seem so huge at the time but we must be strong. Think about how we would feel if we had no fear and live life like that.
The future is ours! A little hard work and sweat never hurt anyone! If we realize that these pains are just small bumps（凸块）on our road to success we will realize that our growing pains
are actually growing gains!
21. According to Paragraph 1, we learn that when we are young ______________.
A. life is full of joy
B. life is easy for us
C. we know we can stay young forever
D. we sometimes can't do things we like
22. The underlined word “obstacles” in Paragraph 2 means the things that__________.
A. make it easy for you to do something
B. make it difficult for you to do something
C. make you happy
D. make you full of energy
23. When the author was young, she was forced by her parents to _____________.
A. take music lessons
B. turn gains into pains
C. look back on hardships
D. live a successful life by suffering a lot
24. What can be inferred from the last paragraph?
A. A little hard work and sweat are harmful to us.
B. We all have to experience growing pains.
C. Growing pains are necessary for us to grow up.
D. Life without fear is a better choice for us.
B
The well-known adventurer(冒险家) and explorer Steve Fossett, born in 1944 in America, was famous for extraordinary(非凡的, 特别的) efforts setting world records in flying, ballooning and sailing. He set or broke over 100 records in five different sports, many of which are still held. Many of his most extraordinary adventures were as a pilot. He once said that he did not like risks(冒险). This might sound strange considering his activities. But he said what he tried to do was to reduce risk with careful planning, technological development and the help of the best scientists and other experts. In 2007, during a short-distance light, his plane disappeared and he died at the age of 63.
In 1903 Benjamin Spock was born in America. After he attended Yale University he joined a sports team that competed in rolling boats，which in 1924 won the gold medal at the Olympic Games in Paris. He used to work at a camp for disabled children for three summers during his years at Yale. And the experience probably led to his decision to enter Yale Medical School, and finally completed his medical degree at Columbia in New York. From 1933 he worked as a baby doctor, trying to fit the theories (理论) about how children develop with
what mothers told him about their children. During the 1950s, Dr Spock became famous. He wrote articles for magazines，appeared on TV programs，taught at universities and gave speeches to talk to parents about their concerns (担心). Benjamin died in 1998 at 94. Yet his advice continues to affect the lives of millions of children and their parents.
An 80-year-old Japanese mountain climber who has had four heart surgeries (手术) reached the top of Mount on Thursday, becoming the oldest to climb up the world’s highest mountain on May 23，2013. It was Yuichiro Miura. As a famous adventurer, he skied down Everest from the South Col in 1970, a deed that became the subject of a documentary. He has since skied down the highest mountains on each of the seven continents, following the tradition of his late father, who skied down Europe’ Mont Blanc at 99. “ If you wish strongly, have courage and endurance, then you can get to the summit (顶峰) of your dream. ” Miura said.
25.What is the main achievement of Benjamin Spock according to the author?

The English language is changing, and you are responsible! Whether we consider changes in grammar, spelling, pronunciation, or the very vocabulary of the language, you have played your part and continue to do so.
When we first learned basic grammar and spelling, perhaps in elementary school, we might
have gotten the impression that these things were sacred. The rules that apply to such things might have been presented as unchanging and unchangeable. While this way might be helpful for teaching children, it is far from accurate.
The English language, like many others, is a living, growing, ever-evolving thing. Like it or not, you are involved in this change. These changes take many forms. Grammar and spelling have changed greatly over the years and centuries, with the spelling differences in different countries today a reflection of this. While the language of a thousand years ago might be called English, most of us would hardly recognize it today as the same language.
The first involves changes in the pronunciation of words. Many are familiar with the differences between the British and American ways of pronouncing certain words. In addition to these differences, the pronunciation of many words has changed over the years because of how you have decided to pronounce them. For example, consider the word "err." The traditional pronunciation of this word rhymes with the word "her." Older dictionaries show this to be the primary or only pronunciation. However, in recent years, more and more people have been pronouncing it so that it sounds like "air." Another change in the language involves the addition and removal of words. The makers of dictionaries decide which words deserve to be officially adopted as part of the English language. Through the centuries, many words have come from other languages. In fact, English has probably done this more than any other language in the world, which is why spelling and pronunciation rules for English have so many exceptions.
Of course, many slang words have been just short-lived fashions that have died out quickly. Others, though, have been adopted by mainstream society and become respectable, as have many technical terms. So then remember, the next time you repeat the newest expression to hit the street, or make up your own words, you may be contributing to the future of the English language.
28. When we begin to learn English, we think _________.
A. it is interesting to pick up a new language
B. English rules are wrongly presented in fact
C. grammar and spelling rules are unchangeable
D. only adults have the ability to affect a language
29. What can we know from paragraph 3?
A. We can change the English language.
B. Many languages are changing over years.
C. English has changed little in the past 1,000 years.
D. There were main changes in grammar and pronunciation.
30. Which of the following is the best title for the passage?
A. Foreign words involved in English.
B. The British speaks differently from Americans.
C. English language is changing over years.
D. You can change the English language.

英语期中考试试卷 Part I Reading Comprehension (10×4 = 40) Passage One Television has opened windows in everybody's life. Young men will never again go to war as they did in 1914. Millions of people now have seen the effects of a battle. And the result has been a general dislike of war, and perhaps more interest in helping those who suffer from all the terrible things that have been shown on the screen. Television has also changed politics. The most distant areas can now follow state affairs, see and her the politicians before tan election. Better informed, people are more likely to vote, and so to make their opinion count. Unfortunately, television's influence has been extremely harmful to the young. Children do not have enough experience to realize that TV shows present an unreal world; that TV advertisements lie to sell products that are sometimes bad or useless. They believe that the violence they see is normal and acceptable. All educators agree that the "television generations" are more violent than their parents and grandparents. Also, the young are less patient. Used to TV shows, where everything is quick and interesting, they do not have the patience to read an article without pictures; to read a book that requires thinking; to listen to a teacher who doesn't do funny things like the people on children's programs. And they expect all problems to be solved happily in ten, fifteen, or thirty minutes. That's the time it takes on the screen. 1. In the past, many young people ______. A) knew the effects of war B) went in for politics C) liked to save the wounded in wars D) were willing to be soldiers 2. Now with TV people can ________. A) discuss politics at an information center B) show more interest in politics C) make their own decisions on political affairs D) express their opinions freely 3. The author thinks that TV advertisements ______. A) are not reliable on the whole B) are useless to people C) are a good guide to adults D) are very harmful to the young 4. Which is NOT true according to the passage? A) People have become used to crimes now. B) With a TV set some problems can be solved quickly. C) People now like to read books with pictures. D) The adults are less violent than the young. 5. From the passage, we can conclude that _______. A) children should keep away from TV B) TV programs should be improved C) children's books should have pictures D) TV has a deep influence on the young Passage Two Many a young person tells me he wants to be a writer. I always encourage such people but I also explain that there's a big difference between "being a writer" and " writing". In most cases these individuals are dreaming of wealth and fame, not the long hour alone at a typewriter. "You've got to want to write," I say to them, "not want to be a writer". The reality is that writing is a lonely, private and poor-paying affair. For every writer killed by fortune there are thousands more whose longing is never rewarded. When I left a 20-year career in
