A city child’s summer is spent in the street in front of his home, and all through the long summer vacations I sat on the edge of the street and watched enviously the other boys on the block play baseball. I was never asked to take part even when one team had a member missing --- not out of special cruelty, but because they took it for granted I would be no good at it. They were right, of course.
I would never forget the wonderful evening when something changed. The baseball ended about eight or eight thirty when it grew dark. Then it was the custom of the boys to retire to a little stoop (门廊) that stuck out from the candy store on the corner and that somehow had become theirs. No grownup ever sat there or attempted to. There the boys would sit, mostly talking about the games played during the day and of the game to be played tomorrow. Then long silences would fall and the boys would wander off one by one. It was just after one of those long silences that my life as an outsider changed. I can no longer remember which boy it was that summer evening who broke the silence with a question: but whoever he was, I nod to him gratefully now. “What’s in those books you’re always reading?” he asked casually. “Stories,” I answered. “What kind?” asked somebody else without much interest.
Nor do I know what drove me to behave as I did, for usually I just sat there in silence, glad enough to be allowed to remain among them; but instead of answering his question, I told them for two hours the story I was reading at the moment. The book was Sister Carrie. They listened bug-eyed and breathless. I must have told it well, but I think there was another and deeper reason that made them to keep an audience. Listening to a tale being told in the dark is one of the most ancient of man’s entertainments, but I was offering them as well, without being aware of doing it, a new and exciting experience.
The books they themselves read were the Rover Boys or Tom Swift or G.A.Henty. I had read them too, but at thirteen I had long since left them behind. Since I was much alone I had become an enthusiastic reader and I had gone through the books-for-boys series. In those days there was no reading material between children’s and grownups’ books or I could find none. I had gone right from Tome Swift and His Flying Machine to Theodore Dreiser and Sister Carrie. Dreiser had hit my young mind, and they listened to me tell the story with some of the wonder that I had had in reading it.
The next night and many nights thereafter, a kind of unspoken ritual ( 仪 式 ) took place. As it grew dark, I would take my place in the center of the stoop and begin the evening’s tale. Some nights, in order to taste my victory more completely, I cheated. I would stop at the most exciting part of a story by Jack London or Bret Harte, and without warning tell them that that was as far as I had gone in the book and it would have to be continued the following evening. It was not true, of course; but I had to make certain of my new-found power and position. I enjoyed the long summer evenings until school began in the fall. Other words of mine have been listened to by larger and more fashionable audiences, but for that tough and athletic one that sat close on the stoop outside the candy store, I have an unreasoning love that will last forever.
1.Watching the boys playing baseball, the writer must have felt _____.
A.bitter and lonely B.special and different
C.pleased and excited D.disturbed and annoyed
2.The writer feels grateful even now to the boy who asked the question because the boy _____.
A.invited him to join in their game
B.liked the book that he was reading
C.broke the long silence of that summer evening
D.offered him an opportunity that changed his life
3.According to Paragraph 3, story-telling was popular among the boys basically because _____.
A.the story was from a children’s book
B.listening to tales was an age-old practice
C.the boys had few entertainments after dark
D.the boys didn’t read books by themselves
4.The boys were attracted to Sister Carrie because _____.
A.it was written by Theodore Dreiser
B.it was specifically targeted at boys
C.it gave them a deeper feeling of pleasure
D.it talked about the wonders of the world

Music for Humans and Humpback Whales
As researchers conclude in Science, the love of music is not only a universal feature of the human species, but is also deeply fixed in complex structures of the human brain, and is far more ancient than previously suspected.
In the articles that discuss the field of bio-musicology, the study of the biological basis for the creation and appreciation of music, researchers present various evidence to, show that music-making is at once an original human "business", and an art form with skillful performers throughout the animal kingdom.
The new reports stress that humans hold no copyright on sound wisdom, and that a number of nonhuman animals produce what can rightly be called music, rather than random sound. Recent in-depth analyses of the songs sung by humpback whales show that, even when their organ would allow them to do otherwise, the animals converge on the same choices relating to sounds and beauty, and accept the same laws of song composition as those preferred by human musicians, and human ears, everywhere.
For example, male humpback whales, who spend six months of each year doing little else but singing, use rhythms (节奏) similar to those found in human music and musical phrases of similar length—a few seconds. Whales are able to make sounds over a range of at least seven octaves (八度音阶), yet they tend to move on through a song in beautiful musical intervals, rather than moving forwards madly. They mix the sounds like drums and pure tones in a ratio (比例) which agrees with that heard in much western music. They also use a favorite technique of human singers, the so-called A-B-A form, in which a theme is stated, then developed, and then returned to in slightly revised form.
Perhaps most impressive, humpback songs contain tunes that rhyme. "This suggests that whales use rhyme in the same way we do: as a technique in poem to help them remember complex material," the researchers write.
1.The underlined words "converge on" in Paragraph 3 probably means ________.
A. tend towards B. refer to
C. turn into D. put forward
2.Which of the following shows the advanced musical ability in humpback whales?
A. They can remember complex material.
B. They can create pleasing patterns of music.
C. They can make sounds like drums continuously.
D. They can sing along with rhythms of western music.
3.What is the main idea of the article?
A. Animals are able to compose and enjoy music like humans.
B. Human beings borrow ideas in music from humpback whales.
C. Humpback whales are skillful performers in the animal kingdom.
D. Music-making, an ancient activity of both humans and animals.
4.The main purpose of the passage is to ________.
A. argue and discuss B. inform and explain
C. compare and advertise D. examine and assess

When we walk on a street or sit down to have a cup of coffee in a small café in Shanghai, we will often see foreign faces at every turn. Today, foreigners do not come to Shanghai to seek adventures, as they did in the old days, or arrive in the city for a short visit, as some did when China just carried out the opening-up. Instead, many foreigners come to Shanghai to settle in the city. They are attracted by the life in Shanghai and choose to stay in the city. Their stay has made Shanghai more like an international city.
Early in the 1990s, a group of Western-style buildings emerged at the Gubei New District in the southwestern part of the Hongqiao Development Zone in Shanghai. The Western-style buildings, marked by their great arches and the typical flavors of the unique European style, appealed to many foreigners and become their favorite choice when they came to live or work in Shanghai. Foreigners gathered in the zone, enjoying their quiet life there.
As the city further develops, more and more foreigners choose to live in the downtown area where most native Shanghai people live. They live close to local residents and gradually become interated(一体化)into the local life—they learn to cook local dishes, they learn to speak the Shanghai dialect and they celebrate traditional Chinese holidays together with native people. Their lifestyle is becoming more and more similar to that of local residents.
In the past, foreigners that came to Shanghai were mostly representatives(代表)sent to work in the city. Today, however, many foreigners that live in the city are students, business starters or ordinary people. Related information shows that there are more than 50,000 foreigners living and working in Shanghai.
1.Foreigners used to come to Shanghai to_____.
A．start small cafés B．help build houses
C．have a short visit D．learn the Shanghai dialect
2.The underlined word“emerged”in the second paragraph probably means_______.
A．built B．appeared C．stood D．lay
3.In the past, most of the foreigners coming to Shanghai were_______.
A．business starters B．students C．ordinary people D．representatives
4.Which of the following can be inferred from the text?
A．There are fewer foreigners in Beijing than in Shanghai.
B．It is the foreigners who make Shanghai an international city.
C．Many foreigners enjoy the traditional Chinese festivals.
D．The foreigners came to Shanghai to seek for money in the past.
5.The best title for this text would be______.
A．Foreigners Settling in Shanghai B．The Development of Shanghai
C．The Lifestyle of Shanghai People D．Contributions of Foreigners in Shanghai

I have been using the Internet since I was five years old, when my dad first sat me down in front of a computer and connected me to the World Wide Web.
I’ve always felt like a master of the Internet world. MSN, Gmail, Facebook, My space -- I’ve got it all under control. I thought there was nothing more to it besides checking my e-mail and wasting my time, until I was introduced to electronic commerce(e-commerce): business on the Internet.
Some online businesses are run from one-room home offices. Others have hundreds of employees across the world. Have you ever heard of Amazon.com, Yahoo.com?
My friends often said they got cheap textbooks on Amazon.com, or had a good deal (交易) on Steve Madden shoes that were on sale at SteveMaden.com. Unfortunately for me, I continued my “e-commerceless” Web-surfing, not knowing about all the deals I was missing out on.
That is, of course, until my sister finally sold the idea to me.
“Why are all these packages arriving in the mail for you, Katy?”I asked her one day. Strange envelopes (信封) had been put on our doorstep for weeks now, each one always addressed to my sister; and we all know little sisters should never be getting more mail than their elders!
“Oh, it’s the things I ordered online!” she answered. I watched speechlessly as she opened them. There was no way our parents were letting her spend that much money- online or off!
“How much did all of this cost?”
“Oh, only about $15 in all!”She said excitedly.“Everything on eBay is on sale! It’s a way better than going to the store.”
I felt as if there had been a store right in my backyard that I had never walked into! That week, I ordered a used Spanish textbook for my summer course online for 10 percent of the publishing price. A few days later, I bought an iPod protector and a book or two via the wonderful eBay.com.
1.From the first two paragraphs we can conclude that the writer___________.
A. had no experience using computers
B. had no idea of what e-commerce is
C. only enjoyed checking e-mail on the Internet
D. thought surfing the Internet was a waste of time

A. he stopped web-surfing
B. he visited a store in his backyard
C. his sister explained the packages she got by mail
D. his friends told him about the online deals they made
3.We can infer from the last paragraph that the writer____________________.
A. never enjoyed shopping that much
B. loves the big store in his backyard
C. feels he is a true master of the Internet
D. has begun to enjoy online shopping
