The “Doorman”

On a trip to California, my family stopped for lunch. As we walked toward the entrance to the restaurant, a man, with a _36 beard and dirty hair, jumped up from a bench and opened the door for us. Regardless of his _37 ,he greeted us in a friendly way.

Once inside, my daughters whispered, “Mom,he _38 _ ” After we ordered our lunch, I explained, telling the kids to look 39 _the dirt. We then watched other customers approach the restaurant but many 40 _ him. Seeing this rudeness truly upset me. The day I became a mother, I had resolved to set a good 41 _ for my children. Yet sometimes when thin gs didn’t go right, being a good example was 42_When our meal arrived,I realized I had left the car-sick pills in the truck. With the windiest trip ahead, the kids needed them, so I 43 _myself from the meal and went to get them.

Just then, the “doorman” was opening the door for a couple. They rushed past him without even acknowledging his 44 _Letting them in first, I said a loud “thank you” to him as I 45 _ .

When I returned, we talked a bit. He said he was not allowed inside 46 _he purchased food. I went back and told my family his 47 Then I asked our waitress to add one soup and sandwich. The kids looked 48 _as we had already eaten,but when I said the order was for the “doorman”,they smiled. When it was time to 49 _ our trip, I noticed the “doorman” enjoying his meal. Upon seeing me, he stood up and thanked me heartily. He then 50 _ his hand for a handshake and I gratefully accepted. I suddenly noticed the tears in his eyes—tears of 51_

What happened next drew great astonishment: I gave the “ doorman” a 52 _ ! He pulled away, with tears 53 _ down his face.

Back in truck, I fell into deep thought. While we can’t choose many things in life, we can choose when to show gratitude. I said thanks to a man who had 54 _held open

a door for me,and also said thanks for that 55 _ to teach my children by example.

Multitasking

People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted (分心) and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah. Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (寻求刺激) or imperative (冲动) they were. They then evaluated the participants’multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.

Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.

“People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.

Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.

The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though th ey’re dangerous.”

67. The research led by Sanbonmatsu indicates that people who multitask .

A. seek high productivity constantly

B. prefer handling different things when getting bored

C. are more focused when doing many things at a time

D. have the poorest results in doing various things at the same time

68. When Sanbonmatsu and his colleagues conducted their research, they .

A. assessed the multitasking ability of the students

B. evaluated the academic achievements of the students

C. analyzed the effec ts of the participants’ tricky mental tasks

D. measured the changes of the students’ understanding ability

69. According to Sanbonmatsu, people multitask because of their _.

A. limited power in calculation

B. interests in doing things differently

C. inability to concentrate on one task

D. impulsive desire to try new things

70. From the last paragraph, we can learn that multitaskers usually .

A. drive very skillfully

B. go in for different tasks

C. fail to react quickly to potential dangers

D. refuse to explain the reasons for their behavior

七选五:

Apathy

Apathy is a state of lacking interest, enthusiasm or concern. 71 _ They may also exhibit unfeelingness. Christians have condemned apathy as a lack of love and devotion to God and His works.

72 _ Also meaning “absence of passion” in Greek, the term “apatheia” was used by the Stoics(禁欲主义者)to show a desirable state of indifference towards events and things which lie outside one’s control.

The modem concept of apathy became well known after World War I,when it was called “shell shock. ” Soldiers, living in the trenches among the bombing and gun fires, saw the battlefields filled with dead and wounded companions. 73 _ In 1950,US novelist Passos wrote “Apathy is one of the characteristic responses of any living being when it is subjected to something too tense or too complicated to deal with. ” US philosopher Robert M. Hutchins summarizes the concerns about political indifference. He claims that the death of democracy is not likely to be a sudden murder from ambush (埋伏)74 _

There may be other things contributing to a person’s apathy. Activist Dave Meslin argues that apathy is often the result of social systems actively blocking engagement and involvement. He describes various barriers that prevent people from knowing how or why they might get involved in something. 75 _These include: political media that make it difficult for potentially interested people to find relevant information,and media descriptions of heroes as “ chosen ” by outside forces rather than self-motivated. He suggests that we redefine social apathy as a result of poorly designed systems that fail to invite others to participate.

A. It will be a slow process of fading away from apathy and indifference.

B. Apathetic people may lack a sense of purpose or meaning in their life.

C. He focuses on designed choices that deliberately or indeliberately exclude people.

D. The word “dispassion” is used for “apatheia”,so as not to confuse it with apathy.

E. So they gradually developed a sense of disconnected numbness to normal social interaction.

F. Although the word “apathy” originates from “apatheia”,it is important not to confuse the two terms.

G. Author John McManamy argues apathy is a psychological problem for some

depressed people,in which they get a sense that “nothing matters”.

The weather’s nice, and the youngsters are out of time. Here are a few tips to help you along the way: Nature is all around us. 37 For small kids, there’s likely plenty in the backyard, courtyard, or schoolyard. National parks are great, but kids foster a deep connection with nature close to home! 38 Don’t worry too much about what to do once you arrive at your nature-rich destination. What kids really need is free time to engage all their senses and use their imaginations. You can learn too. What counts is simply to get out there, show that you value the outdoors, and be ready to have fun. 39 In fact, it is not necessary for you to know anything at all about science or nature. And remember, questions are more powerful than answers anyway! Sit back and watch your kids learn. Don’t be too much of a helicopter parent, always saying “no”. Instead, try to spare more time to stay with your kids when necessary.

Everything about the school seemed so difficult. When I got home, my parents said, “You’re nervous and that’s okay. Everyone is afraid of high school.”36 I wanted to be strong, so I refused to let anyone know about my fear, even my closest friends. On the first day I was late for every class and was constantly lost. 37 Was thi s how the whole year was going to be? I didn’t think I could rise to this challenge, especially carrying a huge backpack that I could hardly lift. It was so big that I could knock someone out with it! The schoolmates seemed to regard me as a fool, and they were probably right. 38 With the exception of falling up and down the stairs a couple of times and getting laughed at, high school was turning out to be not so bad. It was actually much better than middle school and much more challenging. Since then, I’ve been elected vice president of my class, which wasn’t much of a victory since only three people ran for the four positions. It is normal to be scared about a new school. Take a deep breath and relax. 39 Make sure you participate in some out-of-class activities because you’ll find it easier to make friends. Try to do your best, even if it isn’t straight A’s.

Bank, companies, and government agencies use secret code in doing business, especially when information is sent by computer. People have used secret codes for thousands of years. 36 Code breaking never lags (落后) behind code making. The science of decoding and reading coded messages is called cryptography. There are three main types of cryptography. 37 For example, the first letters a re “My elephant eats too many eels” spell out the hidden message “Meet me.” 38 You might represent each letter with a number, for example, let’s number the letters of the alphabet, in order, from 1 to 26. If we substitute a number for each letter, th e message “Meet me” would read “1 3 5 20 13 5”. A code uses symbols to replace words, phrases, or sentences. To read the message of a real code, you must have a code book. 39 For example, “bridge” might stand for “meet” and “out” might stand for “me”.The message “bridge out” would actually mean “Meet me”. 40 However, it

高考英语阅读理解专题训练---七选五 Passage 1 Tips for Improving the Communication in Your Relationship There is a lot more to effective communication in a relationship than just talking about the weather. ____71_____Doiing so will help you to create a more intimate and productive relationship. In this article, we have some tips that will help you enhance the communication between you and your partner so you can start having a better relationship. 1.Listen Carefully Before Responding Sometimes in the heat of an argument, we will react to something that is said before we really understand what is being said. _______ This is more important than responding automatically. 2.Keep It Cool When Disagreeing When a discussion starts turning into an argument, it can go in an ugly direction. Avoid this by sticking to the point and not bringing up old arguments. ________ Then you can resume the conversation later with clearer heads and a fresh perspective. 3.______ It can be difficult if you weren’t raised in a family that did much communicating, but there are things you can do to help yourself be more open and honest with your partner. _______ You should take responsibility on someone else! There is no denying that this can be a tough first step, especially if the relationship has already fallen into less supportive communication habits. But if you don’t fix it now, it will only get worse. It takes a real effort from both parties to build the trust that can help save a relationship. A.Share Your Feelings Openly B.Learn To Have Fun Together C.Spending time together will help increase intimacy D.Sometimes the best thing to do is to take a break and cool off. E.Take the time to really listen to what your partner is saying F.It is important to start sentences with “I feel…” instead of “ You make me feel…” G.Real communication involves honesty, having fun and learning to avoid arguments. Passage 2 How to Overcome Worry When we worry about an event that may not occur, we waste precious energy and time. There is a philosophy that if we worry about something it is actually more likely to happen; we attract the negative event through our negative thoughts. Worry never helps, it just leaves us without peace of mind. ________ Here are a few steps that will help. 1.Concentrate on the Present Worry means we are advancing into the future and speculating that the worst might happen. Worrying about the future is not helpful. ______ Many religious texts tell us, “Do not worry about tomorrow, for tomorrow will take care of itself.” 2.Imagine How Good Things Can Occur If we concentrate on the negative, it is likely to create negative emotions and negative thoughts. If we worry, this in itself is a problem for us; it becomes a vicious cycle(恶性循环). If you find yourself often in a state of fear or worry, make conscious effort to visualize the best overcome. Imagine yourself doing the best you can in the circumstances and then being detached(分开) from

But at times it seems too difficult and too far out of reach. 36 ___ Here’s a handful of ways that will set you in the right direction. ●37 Do not follow the people who make you feel not-good-enough. Why do you follow them? Are you hoping that eventually you will feel empowered because your life is better than theirs? Know that your life is your own; you are the only you in this world. ●Forgive yourself for mistakes that you have made. We are often ashamed of our shortcomings, our mistakes and our failures. 38 You will make mistakes, time and time again. Rather than getting caught up in how you could have done better, why not offer yourself a compassionate (有同情心) response? "That didn’t go as planned. But, I tried my best." ●Recognize all of your strengths. Write them down in a journal. Begin to train your brain to look at strength before weakness. List all of your accomplishments and achievements. You have a job, earned your degree, and you got out of bed today. 39 ●Now that you’ve listed your strengths, list your imperfections. Turn the page in your journal. Put into words why you feel unworthy, why you don’t feel good enough. Now, read these words back to yourself. 40 Turn to a page in your journal to your list of strengths and achievements. See how awesome you are? A. Feeling upset again? B. Where do you start? C. Nothing is too small to celebrate. D. Remember, you are only human. E Set an intention for self-acceptance. F. Stop comparing yourself with others.
