Part III: Reading Comprehension

Questions 41 to 45 are based on the following passage.

It would be a fairly accurate statement to say that, when I was in elementary school and high school, I

was a painfully shy child. I usually kept to myself, had only a few friends, and rarely spoke in class. My

parents were always very busy, so they never pushed me to become more involved in activities and meet

more people. I was perfectly happy by myself. I spent much of my time with my nose buried in a book. The

only times that I ventured away from the comforts of my bedroom were when I explored the seemingly

endless aisles of stocked bookshelves at my favourite bookstore.

In retrospect, it was no surprise that I read with such an incredible appetite. Reading was my escape. My favourite books were adventure and travel stories—stories that brought the readers to exotic, unexplored, or dangerous places. These were places I longed to go, and they were adventures I yearned to experience, but I knew it was all just a fantasy. I had a hard time working up the nerve to talk to a fellow classmate, I knew there was no way I could travel around the world and live out one of these adventures. Therefore, I read. I read every book I could find that promised adventure, excitement, or escape. By the time I graduated from high school, I had probably read more books than our school had in its library. It was quite an achievement, but no one knew about it except for me. I told no one because I had no one to tell. My only friend was Justin, and that relationship only existed because we had been next-door neighbours for fifteen years.

Like most of my classmates, I applied to college and eventually worked up the courage to go. It wasn't easy. I had lived at home with my parents my whole life, and I rarely ever thought about leaving. However, it had finally become inevitable; I couldn't stay with them forever. I attended a local college and moved out to live in a dormitory with a roommate. It would be an understatement to say that I was nervous. I was terrified.

My roommate's name was Greg, and the first few weeks of school were very awkward. He kept trying to start conversations and be friendly. I was able to answer his questions, of course, but I found it difficult to keep the conversation going. I just wasn't used to it—I had no practice at this sort of thing. Then one day I returned from an afternoon class and found him reading a Jack London book. Suddenly, I found that I had a hundred questions to ask Greg. Did he like Jack London? Which was his favourite book? Did he read a lot? What other authors did he like? The list was endless.

To my surprise, Greg was also in love with adventure and travel books. One of his dreams was to travel around the world and follow in the footsteps of some of history's greatest explorers. There must have been magic at work that day. It was as if my shyness suddenly disappeared. Greg and I talked for hours about our favourite books and dreams of travel. I also found it easier to talk to other people at school and make friends

since that day. I felt like the world opened up to me. So many things suddenly seemed possible. In fact, Greg and I are planning a great adventure for this summer! It may have taken me a while, but I finally found a way to break out of my shell and start enjoying life.

41. Which of the following is a rite of passage that helped the writer to become less shy?

A. Attending high school.

B. Reading many books.

C. Attending college.

D. Planning a great adventure.

42. In which paragraph does the author compare his desire to read to hunger?

B. My College Life

mean by this statement?

Part III: Reading Comprehension

Questions 41 to 45 are based on the following passage.

When we're young, we can't wait to grow up and get on with life. When we're adults, we long for the carefree days of our youth when we could play all day without worry. This is one of the greatest ironies of life. Indeed, "the grass is always greener on the other side." It is a harsh truth that humans always want what they can't have. It's our nature.

That's why it's good practice to instill in our children a healthy respect for childhood. Too many adults seem to be in a hurry for children to grow up. We always ask them, "What do you want to be when you grow up?" We repeatedly tell them, "You can do/have that when you're older." We continually encourage them, "When you grow up, the world will be yours and you can make your dreams come true." It's no wonder, then, that children seem to be in such a rush to grow up, get older, and demand everything that we tell them is coming to them.

Children should be free to play the day away. We should encourage them to use their imagination, create entire worlds in a cardboard box, and explore their backyard as if they were exploring an undiscovered country. You cannot put a price on an active and fertile imagination, nor can you overestimate the value of an inquisitive mind, a respect for the environment, and an urge to question why everything is as

it is. These traits are all developed and nurtured when we're children and, without them, we would not be able to function as adults in the modern world.

Research has shown that children are happiest and healthiest when they have the freedom to act like children. This may seem obvious, but it's often forgotten as parents push their children to study harder, practice longer, and essentially act like adults. It's important to remember that children are constantly learning. Therefore, they are also learning as they're playing. Exploring nature fosters a respect for the environment that may lead children to become biologists or naturalists. Creating with paint and crayons instills a love of art that might help develop young artists or musicians. Playing make-believe stimulates the imagination in a way that writers, filmmakers, and actors find most useful. Building with blocks helps the mind understand how things are constructed and might lead to an interest in engineering.

It's true that play helps develop skills that will be used later in life. However, this should not be the sole purpose of play. Children should play because they're children. It's how they stay happy, healthy, and young. Why should we push them to be something they're not?

41. Which of the following sentences is the main idea of this passage?

A. It is a harsh truth that humans always want what they can't have.

B. Too many adults seem to be in a hurry for children to grow up.

C. Children should be free to play the day away.

D. It's true that play helps develop skills that will be used later in life.

42. Which of the following would the writer of this passage likely NOT agree with?

A. Adults should understand that children learn while they play.

B. It is important for children to play and act young.

C. Many games help children appreciate potential careers.

D. Children should concentrate on their schoolwork above everything else.

43. "The grass is always greener on the other side" means _____.

A. other situations always seem better than the ones we are in

B. people always lack confidence in themselves

C. people prefer to live in a less barren land

D. people always want their children to grow up fast

44. This passage is best described as _____.

A. a first-person memoir

B. a dramatic dialogue

C. a persuasive essay

D. an entertaining story

45. What does the writer mean by "You cannot put a price on an active and fertile imagination"?

A. The ability to think creatively is worthless.

B. The ability to think creatively is invaluable.

C. The ability to think creatively helps children develop.

D. The ability to think creatively is a natural part of childhood

3.Many products for sale seem to scream at us, "Buy me! Buy me!" Advertising is a big busin ess in our world with many products competing for our attention. Think of the last time you boug ht clothes. You probably noticed the variety of colors, patterns, fabrics and brands you could choo se from. Which kind of soft drink would you like to have today or what kind of computer do you want? Advertisers are skilled in the art of making their products look the best to appeal to our se nses. But products aren't always what they seem. Sometimes advertising is deceptive and as cons umers ,we must be careful about what we choose to buy. It is important to learn to compare prod ucts and identify our purpose in purchasing the things we need. But the good thing about advertising is that it helps people to make decisions and refine thei r choices. In the United States, the Ad Council creates timely public service messages to the nation. Th eir purpose is to raise awareness of public problems that citizens can respond to. Inspiring ads ca use individuals to take action and even save lives. Pollution in America, for example has been red uced over the years because of the creative Public Service advertisements that the council provid es" Please, please don't be a litter bug, 'cause every 'litter bit' hurts." Many families have taught t heir children to place litter in the trash can in response to this catchy phrase, which has affected g enerations as each succeeding generation has taught their children not to litter. 4.Nature imposes difficult conditions upon the earth from time to time . The tornado and fo rest fire destroy natural resources ,homes and other structures ,and very often harm or kill peopl e . Technological tragedies happen with little or no warning as we see trains crash and airplanes f all from the sky shortly after take-off. As tragic as calamities are , they seem to bring out the best in human nature . people trained in em ergency care arrive at the scene and begin assisting the inj ured .Others come with equipment to remove debris. Men , women ,and young people willingly c ome to the scene of an accident , hoping to be of help in some way . These selfless acts of kindne ss make our world a better place . compassion eases the wounds of calamities. American Airlines flight number 587 crashed less than three minutes after taking off from JF K Airport in New York in November,2001. Witnesses s aw an engine fire develop on the plane’s nu mber one engine located under the left wing of the aircraft .seconds later ,the airliner crashed int o eight homes ,completely destroying four of them .All 260 people aboard the airplane were kille d along with six people at the crash site ,leaving many people to mourn the loss of their loved on es .the residents (people who live in the area of the crash ) rallied together to comfort those griev ing, while others removed bodies from the wreckage and did the necessary clean-up. 工程实施困难的条件下在地上的时候。龙卷风和森林火灾破坏自然资源,房屋和其他建筑物,和经常伤害或杀死人。技术的悲剧发生在很少或没有预警,因为我们看到火车事故,飞机起飞后不久就从天空坠落。一样悲惨的灾难,他们似乎显示出人性中最好的。在急诊受训的人到达现场并开始帮助受伤的人则跟设备清除残骸。男人,女人,和年轻人自愿来到事故现场,希望能有帮助。这些无私的善举让我们的世界变得更美好。同情减轻灾害的伤口。 美国航空公司587号航班坠毁不到三分钟后从纽约肯尼迪机场起飞,11月2001。目击者看到一个引擎火灾发展在飞机上的1号引擎位于下飞机的左翼,接着后,客机坠毁八家,完全摧毁了四个260名乘客的飞机遇难连同6人在事故现场,造成许多人悼念失去的亲人,居民(住在崩溃的面积)聚集在一起,安慰那些悲伤,而另一些人则从残骸,并把尸体移走必要的清理。 5.Success can be reached in different ways by people in different careers.

The three stories are chosen because they are representative of all participants in this movement: John Parke r is a freed slave who later turned into a courageous “conductor”; Levi Coffin is a brave white “conductor”; Josiah Henson is a slave who struggled his way to freedom with the help of the Underground Railroad. We learn about the name of Josiah Henson at the beginning of the text, yet his full story is not told until the last part. In this way the author achieves coherence of text. 3.Students Analysis The class is made up of 56 students, with 30 girls and 26 boys ,who have a good knowledge of Basic English, but know very little about the American culture behind the language. So in this introduction part, It is necessary to introduce some background information to the students before reading 4.Teaching Objectives Students will be able to: 1.understand the main idea(early civil-rights struggles in the US, esp. the underground Railroad) 2.grasp the key language points and grammatical structures in the text, 3.conduct a series of reading, listening, speaking and writing activities related to the theme of the unit 4.Appreciate the various techniques employed by the writer (comparison and contrast, topic sentence followed by detail sentences, use of transitional devices,etc.); 5.Teaching Procedures: Greetings Step 1 Lead-in T: Today we are going to talk about the ethic heroes in American history, before the class, I’d like to introduce the slavery to all of you. T: Abraham Lincoln was the 16th president of the United States, during his term of office; he led the civil war and abolished the slavery. T: In the battle against slavery, not only did the president try his best to abolish this system, but also the people, especially the black people living in the South America try hard to fight for their own feat. Today, we will introduce some freedom givers in the American history. Before
