My mom takes pride in the fact that I was talking in three and four word sentences before I was ten months old. Some say it’s a gift while others simply think I talk too much.
As my thirties came to a close, I found myself reflecting on my life. I’m very happy and have no significant regrets. However, when I looked back on those times of difficulty, I saw a clear common denominator(特征); I didn’t seem to know when to stop talking. Whether it was hurting someone’s feelings, or having carelessly told a secret, the incident could have been avoided had I closed my mouth sooner. So I decided to practice the power of quiet.
To take this step, I needed to understand how people could sit comfortably in a group and not talk. Why does my husband feel completely content to say nothing in a conversation? He’s highly intelligent and has wonderful opinions but he’ll sit quietly and just listen. Even when he’s asked a pointed question, he’ll answer with few words while still communicating effectively. What a talent!
Can you imagine being happy just listening? In surveying those I know who talk less than I do, I got two answers—they either didn’t feel confident enough to speak up, or they just didn’t feel the need to participate in the conversation. Of course there were other reasons for not talking, but these were the two most popular answers.
The first one didn’t work for me. I’m just fine letting people know what I think about them, and hopefully it will make the conversation much more interesting. The second one didn’t work either. I do feel the need to participate. I feel it physically like an electrical pulse through my body; sometimes it’s so strong that it causes me to behave badly in the form of interrupting or speaking in an unusually loud voice. I had to look further.
An interesting thing happened on this journey to the power of quiet. During my weekly yoga class, it came to me like an answer so clear that the words rang in my head like soft, heavenly bells.
I talked too much so people would know I cared about them. It was my way of taking care of those I love. I decided before my fortieth birthday, that from that day forward, those around me would know I loved them, and cared what they thought and felt, but I was going to practice the power of quiet.
As my forty-second birthday approaches, I can say that deciding to talk less has been more about focusing on quality rather than quantity. I’ve found that listening more shows those who I care about that I really do care how they feel. Now when I break in, it means more to them. Oh, sure, I still have my short periods of talking too much, but for the most part this has been one resolution that I can call a success.
21. In Paragraph 3 the writer mentions her husband mainly ______.
A. to show how one communicates effectively
B. to explain the reason for his silence in a conversation
C. to give an example of those who have the power of quiet
D. to give her high opinion of his communication skills

Your friends might be in Australia or may be just down the road, but they are all just a few clicks(点击) away. Life has changed for millions of young people across the world who now make friends online. Whether you use chat-rooms, QQ, MSN or ICQ, you are a member of this group.
“I don’t often talk with my parents or grand-parents, but I talk a lot with my old friends on QQ,” said Fox’s Shadow, the online name used by a girl student in China. “Most of my classmates use QQ after school.”
QQ is the biggest messaging service in China. A recorder from Tencent, the company which developed QQ, shows that 4 million people used it one Saturday night in October. And probably Fox’s Shadow was one of them. “I log in(登陆) on Friday nights, and Saturdays when I feel everything around me boring. I usually spend about ten hours chatting on-line every week,” she said. “But I never talk with strangers, especially boys or men.”
Even though she likes chatting, she is careful about making friends with strangers online. “You don’t know who you’re talking to. You should always be careful about whom you believe in online.” Many people would like to meet offline when they feel they have got to know someone very well. Fox’s Shadow once met one of her online friends face to face. It was a girl who was a football fan like herself and they went to a football match together.
A 16-year-old Beijing boy, named Bart Simon online, dislikes QQ uses. “I used to chat on QQ, but I found that most people were talking about foolish things,” he said. Now he chats online in English, using MSN. “I only chat online because I’ve got friends in Japan, the US and Singapore,” he said. “I want to learn more about foreign cultures.” But he spends little time chatting on QQ as he sees it as a waste of time and money.
“If you are really addicted to it, sometimes you can’t give your mind to your lessons,” he said. “And friends in your real life are always more important than those so-called friends you meet online.”
25. People meet face to face offline when they think they _____.
A. have known each other well
B. have the same interest
C. have enough free time
D. have nothing to do
26. Fox’s Shadow thinks QQ is ______.
A. the biggest messaging service in China
B. a good place to spend her time when bored
C. a safe place to chat with strangers
D. the best place to make friends

A. it is wonderful to see your friends by clicking
B. it is easy and fast to get in touch with your friends

Shopping in the United States changes a lot.About ninety years ago most people shopped in small stores that were owned by one person or a family.Women went from the bakery to the butcher's to the grocer and on to the fruit and vegetable seller in order to get their food for the week.
Then about sixty years ago, supermarkets were born.In a supermarket, people could get all the different kinds of food they needed without going to different stores.
The next big change in shopping in the United States was the shopping mall.A shopping mall is a group of stores under one roof.Because malls allowed people to shop without worrying about the weather, they soon became very popular.The mall became a place for people to socialize in addition to shopping.If you walk through a mall, you will see older people sitting, chatting and drinking coffee.Malls are places for teenagers to hang out.Many teens will often just "go to the mall" and spend time with their friends.
The recent change in American shopping was the superstore.Large chain stores such as Wal-Mart, Office Depot and Toys "R" Us have been built all across the United States.Because they are so large, they can buy goods at a great discount and sell them much cheaper than smaller stores.
Sometimes, when they are built near small towns, many of the small town stores have to close.They just cannot compete with their giant neighbors.
And now, online shopping is becoming more and more popular all over the States.People are too busy to go to the physical stores, so they go shopping over the Internet.Online shopping has lots of advantages.For instance, online stores are usually available 24 hours a day.Searching or browsing online shops can be faster than browsing the physical stores.While, online shopping also has its disadvantages.People are at higher risk of being cheated on the part of the merchant than in a physical store.And privacy of personal information may be let out.
24.Which of the following shows the right order of shopping development in the United States?
①small stores ②superstores ③shopping malls ④shopping online ⑤supermarkets
A.①②③④⑤ B.①⑤②③④
C.①⑤③②④ D.②③④①⑤
25.Which is the place for people to spend time with others according to the passage?
A.Shopping malls. B.Small stores.
C.Supermarkets. D.Superstores.
26.Why can the superstores sell products at much lower prices?
A.Because they are built near small towns.
B.Because they are across the United States.
C.Because they sell all kinds of products people need.
D.Because they can buy goods at a reduction in the price.
27.What's the disadvantage of online shopping according to the passage?
A.Wasting time. B.Leaking personal information.
C.Fixed prices. D.No chance to do physical activities

In the early 1980s, one of our neighbors asked my mom if she would make a few gift baskets for her to give as gifts for the holidays. My mom agreed and news of the unique gift baskets my mom was making spread like wildfire throughout the neighborhood. My mom was busy throughout the holiday season, so she asked a friend to help her. When the orders continued after the holiday season for baby gifts, birthday gifts and more, it occurred to them that maybe this job could be turned into a business and they did it.
My mom went into her business because she had creative ideas. She got orders and filled order. But there was no goal and no real plan. In 1991, my mom’s partner got into financial trouble and there was not enough money to support either mom or her partner.
So if you are led by your creativity or enthusiasm, make sure you ask yourself what you purpose to do your business is. If you don’t set goals, how will you know which direction to go in? Do you want to create jobs and growth in the economy? Are you looking for a hobby? You can’t keep scores if you don’t know what game you are playing.
After my mom’s partner quit, she had to abandon her business to support herself. She swore she would run a business again and do it differently the next time. However, there wasn’t a “next time” for her. She passed away just after her 51st birthday. She never had someone tell her how important having a goal was, she never had a chance to be everything she could be.
There are no right or wrong goals, only the ones that matter to you. Set them so that you can make progress and achieve success, whatever they may mean to you.
9. What did the writer’s mom do after failing in her business?
A. She found a different partner
B. She celebrated her 51st birthday
C. She planned to have a second try with different methods
D. She decided never to run a business again
10. What can we infer from the passage?
A. The writer began her business with a set goal
B. The writer mother was a woman without creativity
C. The writer’s mother died because of her failure in business
D. The writer believes having goals I n mind ensured one’s success
11. How does the writer present his point of view mainly?
A. By providing examples B. By explaining causes
C. By making comparisons D. By listing figures

I was in a local store the other day when suddenly I heard the sound of breaking glass behind me. Curiously, I turned around to see 61 had happened. A young mother had turned away from her shopping cart for a second to look at some other goods she was interested in. That second was all it took for her baby boy 62 (lift) a big jar of sauce from his seat in the cart.
63 (unfortunate), the big jar was more than he could handle. I smiled when I walked back and saw the look of complete fear 64 the boy’s face. He seemed not to know why. His arms still remained where the jar 65 (be) a few seconds before. On the floor below the cart the liquid of red was slowly flowing across the passage. After making sure that both Mom and the baby were fine, I went downstairs to get help from a store employee. As I glanced back at them, I saw something 66 truly warmed my heart.
The baby had finally taken his eyes off the 67 (break) jar and looked up at his mom. Instead of 68 (scold) him, she smiled down at him. I knew then that this Mom would give her son a lifetime full of 69 (laugh) and love. I think we should learn to love. Yet, hard as we try, we often make 70 (thing) messy too.
Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their cats are just as used to the warm shelter (住所) as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pets in danger of serious illness. There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you're cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of non-frozen water.
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet's water. Sometimes owners don't realize that a water bowl has frozen and their pet can't get anything to drink. Animals that don't have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.
24. What do we learn about pets from Paragraph 1?
A. They are often forgotten by their owners. B. They like to stay in warm places.
C. They build their won shelter. D. They are used to living outdoors.
25. Why are pet owners asked to stay with their pets when they are out in cold weather?
A. To help them find shelters. B. To keep them from eating bad food.
C. To know when to bring them inside. D. To keep them company.
26. If pets are left on their own outdoors in cold weather, they may ___.
A. get lost in the wild B. dig deep holes for fun
C. dirty the snow nearby D. run short of clean water
27. What is the purpose of this text?
A. To give practical advice. B. To solve a problem.
C. To tell an interesting story. D. To present a research result.
