AI was waiting for a phone call from my agent. He had left a message the night before, telling me that my show was to be canceled. I called him several times, but each time his secretary told me that he was in a meeting and that he would call me later. So I waited and waited, but there was still no call. Three hours passing by, I became more and more impatient. I was certain that my agent didn’t care about my work, and he didn't care about me. I was overcome with that thought. I started to shout at the phone, "Let me wait, will you? Who do you think you are?"At that time I didn't realize my wife was looking on. Without showing her surprise, she rushed in, seized the phone, tore off the wires, and shouted at the phone, "Yeah! Who do you think you are? Bad telephone! Bad telephone!" And she swept it into the wastebasket.I stood watching her, speechless. What on earth?She stepped to the doorway and shouted at the rest of the house, "Now hear this! All objects in this room—if you do anything to upset my husband, out you go!"Then she turned to me, kissed me, and said calmly, "Honey, you just have to learn how to take control." With that, she left the room.After watching a crazy woman rushing in and out, shouting at everything in sight, I noticed that something in my mood had changed. I was laughing. How could I have trouble with that phone? Her antics helped me realize I had been driven crazy by small things. Twenty minutes later my agent did call.

When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good You may dislike some types offood because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.9.We can infer from the text that humans and animals ________.A. depend on one sense in choosing foodB. are not satisfied with their foodC. choose food in similar ways.D. eat entirely different food10.Which of the following eats only one type of food?A. The white butterfly.B. The small bird.C. The bearD. The fox11.Certain animals change their choice of food when ______.A. the season changesB. The food color changesC. They move to different placesD. They are attracted by different smells. 12.We can learn from the last paragraph that _____.A. food is chosen for a good reason.B. Some people care little about healthy dietC. some people have few choices of foodD. French and British food is good.DMake Up Your Mind to SucceedKind-hearted parents have unknowingly left their children defenseless against failure.The generation (age) born between 1980 and 2001 grew up playing sports where scores (marks) and performance (show) were played down because “everyone's winner.” And their report cards sounded more positive than ever before.As a result, Stanford University professor Carol Dweck, PhD, calls them “the overpraised generation.”Dweck has been studying how people deal with failure for 40 years.Her research has led her to find out two clearly different mind-sets that have a great effect on how we react to it.Here's how they work:A fixed mind-set is grounded in the belief that talent is genetic – you're a born artist, point guard, or numbers person.The fixed mind-set believes it's sure to succeed without much effort and regards failure as personal shame.When things get difficult, it's quick to blame (liability), lie, and even stay away from future difficulties.On the other hand, a growth mind-set believes that no talent is entirely heaven-sent and that effort and learning make everything possible.Because theego (自尊) isn't on the line as much, the growth mind-set sees failure as a chance rather than shame.When faced with a difficulty, it's quick to rethink, change and try again.In fact, it enjoys this experience.We are all born with growth mind-sets.(Otherwise, we wouldn't be able to live in the world.) But parents, teachers, and instructors often push us into fixed mind-sets by encouraging certain actions and misdirecting praise.Dweck's book, Mind-set:The New Psychology of Success, and online instructional program explain this in depth.But she says there are many little things you can start doing today to make sure that your children, grandchildren and even you are never defeated by failure.13.What does the author think about the present generation?A.They don't do well at school. B.They are often misunderstood. C.They are eager to win in sports D.They are given too much praise.14.A fixed mind-set person is probably one who ___ .A.doesn't want to work hard B.cares a lot about personal safety C.cannot share his ideas with others D.can succeed with the help of teachers 15.What does the growth mind-set believe?A.Admitting failure is shameful. B.Talent comes with one's birth.C. Getting over difficulties is enjoyable. D.Scores should be highly valued.第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

AI was waiting for a phone call from my agent. He had left a message the night before, telling me that my show was to be canceled. I called him several times, but each time his secretary told me that he was in a meeting and that he would call me later. So I waited and waited, but there was still no call. Three hours passing by, I became more and more impatient. I was certain that my agent didn’t care about my work, and he didn't care about me. I was overcome with that thought. I started to shout at the phone, "Let me wait, will you? Who do you think you are?"At that time I didn't realize my wife was looking on. Without showing her surprise, she rushed in, seized the phone, tore off the wires, and shouted at the phone, "Yeah! Who do you think you are? Bad telephone! Bad telephone!" And she swept it into the wastebasket.I stood watching her, speechless. What on earth?She stepped to the doorway and shouted at the rest of the house, "Now hear this! All objects in this room—if you do anything to upset my husband, out you go!"Then she turned to me, kissed me, and said calmly, "Honey, you just have to learn how to take control." With that, she left the room.After watching a crazy woman rushing in and out, shouting at everything in sight, I noticed that something in my mood had changed. I was laughing.

When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.9.We can infer from the text that humans and animals ________.A. depend on one sense in choosing foodB. are not satisfied with their foodC. choose food in similar ways.D. eat entirely different food10.Which of the following eats only one type of food?A. The white butterfly.B. The small bird.C. The bearD. The fox11.Certain animals change their choice of food when ______.A. the season changesB. The food color changesC. They move to different placesD. They are attracted by different smells. 12.We can learn from the last paragraph that _____.A. food is chosen for a good reason.B. Some people care little about healthy dietC. some people have few choices of foodD. French and British food is good.DMake Up Y our Mind to SucceedKind-hearted parents have unknowingly left their children defenseless against failure.The generation (age) born between 1980 and 2001 grew up playing sports where scores (marks) and performance (show) were played down because ―everyone's winner.‖ And their report cards sounded more positive than ever before.As a result, Stanford University professor Carol Dweck, PhD, calls them ―the overpraised generation.‖Dweck has been studying how people deal with failure for 40 years.Her research has led her to find out two clearly different mind-sets that have a great effect on how we react to it.Here's how they work:A fixed mind-set is grounded in the belief that talent is genetic – you're a born artist, point guard, or numbers person.The fixed mind-set believes it's sure to succeed without much effort and regards failure as personal shame.When things get difficult, it's quick to blame (liability), lie, and even stay away from future difficulties.On the other hand, a growth mind-set believes that no talent is entirely heaven-sent and that effort and learning make everything possible.Because the ego (自尊) isn't on the line as much, the growth mind-set sees failure as a chance rather than shame.When faced with a difficulty, it's quick to rethink, change and try again.In fact, it enjoys this experience.We are all born with growth mind-sets.(Otherwise, we wouldn't be able to live in the world.) But parents, teachers, and instructors often push us into fixed mind-sets by encouraging certain actions and misdirecting praise.Dweck's book, Mind-set: The New Psychology of Success, and online instructional program explain this in depth.But she says there are many little things you can start doing today to make sure that your children, grandchildren and even you are never defeated by failure.13.What does the author think about the present generation?A.They don't do well at school. B.They are often misunderstood.C.They are eager to win in sports D.They are given too much praise.14.A fixed mind-set person is probably one who ___ .A.doesn't want to work hard B.cares a lot about personal safetyC.cannot share his ideas with others D.can succeed with the help of teachers 15.What does the growth mind-set believe?A.Admitting failure is shameful. B.Talent comes with one's birth.C. Getting over difficulties is enjoyable. D.Scores should be highly valued.第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
