Part II Reading Comprehension ( 25 minutes )
Section A
Directions: In this section, there is a passage with several blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. You may not use any of the words in the bank more than once.
?What drives you to succeed as a creative person? Is it the dream of fame, 11 and recognition? Is the thought of seeing your name up in lights that 12 you out of bed in the morning? Having such a strong and clear goal is a 13 motivator and, if you work hard and pay your dues, you can 14 achieve that goal.
However, if you want to be successful without the feeling that you are battling your way through life your motivation to get out of that comfy bed in the morning has to come from somewhere else. There must be
an even bigger motivating driver.
To have 15 and want to be successful is a fine thing but it isn't enough. Ambition and want are just words that describe desire. To understand WHY you have such desires is quite another thing. True 16 , true art in any form, comes from passion. Great actors aren't great because of their technique. Anyone can learn technique. They move an audience as great actors because of their passion. Passion is the driver that 17 every bone and breath in your body to achieve.
If your desires are not in alignment with your passion you can be successful but you will not be 18 , satisfied. You will live a rich famous life and still 19 for the elusive thing. You will get up in the morning wondering what is wrong with you. You have all that you desired yet you feel that there is still something missing. You are missing the nourishment that feeds your soul, your heart.
Above all, be true to yourself, and if you cannot put your heart in it, take yourself out of it. Follow your heart, but be quiet for a while first. Ask questions, and then feel the answer. Learn to trust your heart.
When work, 20 commitment, and pleasure unite to become one and you reach into that deep well where passion lives, nothing is impossible. Through the experience of devoted passion you will reap richer stores of knowledge than any text-book or course of study can give you.

Section B
Directions: There are several passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B),
C) and D). You should decide on the best choice.
?Passage One
Questions 21 to 25 are based on the following passage.
In our culture, the sources of what we call a sense of "mastery" — feeling important and worthwhile —and the sources of what we call a sense of "pleasure" — finding life enjoyable — are not always identical.
Women often are told "You can't have it all." Sometimes what the speaker really is saying is:"You chose
a career, so you can't expect to have closer relationships or a happy family life." or "You have a
wonderful husband and children —what's all this about wanting a career?" But women need to understand and develop both aspects of well-being, if they are to feel good about themselves.
Our study shows that, for women, well-being has two dimensions. One is mastery, which includes self-esteem (自尊), a sense of control over your life, and low levels of anxiety and depression. Mastery is closely related to the "doing" side of life, to work and activity. Pleasure is the other dimension, and it is composed of happiness, satisfaction and optimism (乐观). It is tied more closely to the "feeling" side of life. The two are independent of each other. A woman could be high in mastery and low in pleasure, and vice versa. For example, a woman who has a good job, but whose mother has just died, might be feeling very good about herself and in control of her work life, but the pleasure side could be damaged for a time.
The concepts of mastery and pleasure can help us identify the sources of well-being for women, and remedy past mistakes. In the past, women were encouraged to look only at the feeling side of life as the source of all well-being. But we know that both mastery and pleasure are critical. And mastery seems to be achieved largely through work. In our study, all the groups of employed women rated significantly higher in mastery than women who were not employed.
A woman's well-being is enhanced (增进) when she takes on multiple roles. At least by middle adulthood,
the women who were involved in a combination of roles — marriages, motherhood, and employment —were the highest in well-being, despite warnings about stress and strain.

A) for women, a sense of "mastery" is more important than a sense of "pleasure"该选项共0人选择
B) for women, a sense of "pleasure" is more important than a sense of "mastery"该选项共0人选择

Passage Two
Questions 26 to 30 are based on the following passage.
Like many of my generation, I have a weakness for hero worship. At some point, however, we all begin to question our heroes and our need for them. This leads us to ask: What is a hero?
Despite immense differences in cultures, heroes around the world generally share a number of characteristics that instruct and inspire people.
A hero does something worth talking about. A hero has a story of adventure to tell and a community who
will listen. But a hero goes beyond mere fame.
Heroes serve powers or principles larger than themselves. Like high-voltage transformers, heroes take the energy of higher powers and step it down so that it can be used by ordinary people.
The hero lives a life worthy of imitation. Those who imitate a genuine hero experience life with new depth, enthusiasm, and meaning. A sure test for would-be heroes is what or whom do they serve? What are they willing to live and die for? If the answer or evidence suggests they serve only their own fame, they may be famous persons but not heroes. Madonna and Michael Jackson are famous, but who would claim that their fans find life more abundant?
Heroes are catalysts (催化剂) for change. They have a vision from the mountaintop. They have the skill and the charm to move the masses. They create new possibilities. Without Gandhi, India might still be part of the British Empire. Without Rosa Parks and Martin Luther King, Jr., we might still have segregated (隔离的) buses, restaurants, and parks. It may be possible for large-scale changes to occur without leaders with magnetic personalities, but the pace of change would be slow, the vision uncertain, and the committee meetings endless.

A) generally possess certain inspiring characteristics该选项共0人选择

?正确答案（20分）：Searching for a job is a roller coaster ride! There are some days when you are flying high and there are other days when you are in a free fall and your stomach is in your throat. Having a positive attitude is the one thing that will support your entire job search process. Attitude is everything!
If it's not right, you cannot possibly conduct a proactive and effective job search. Do what you need to do to get it right. Sometimes, people need to get the negative thoughts out. You can speak them to a good friend, or write them down on a piece of paper, and be done with it. Life is short! Get your attitude right and get that job!

Part II Reading Comprehension ( 25 minutes )
Section A
Directions: In this section, there is a passage with several blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. You may not use any of the words in the bank more than once.
?What drives you to succeed as a creative person? Is it the dream of fame, 11 and recognition? Is the thought of seeing your name up in lights that 12 you out of bed in the morning? Having such a strong and clear goal is a 13 motivator and, if you work hard and pay your dues, you can 14 achieve that goal.
However, if you want to be successful without the feeling that you are battling your way through life your motivation to get out of that comfy bed in the morning has to come from somewhere else. There must be an even bigger motivating driver.
To have 15 and want to be successful is a fine thing but it isn't enough. Ambition and want are just words that describe desire. To understand WHY you have such desires is quite another thing. True 16 , true art in any form, comes from passion. Great actors aren't great because of their technique. Anyone can learn technique. They move an audience as great actors because of their passion. Passion is the driver that 17 every bone and breath in your body to achieve.
If your desires are not in alignment with your passion you can be successful but you will not be 18 , satisfied. You will live a rich famous life and still 19 for the elusive thing. You will get up in the morning wondering what is wrong with you. You have all that you desired yet you feel that there is still something missing. You are missing the nourishment that feeds your soul, your heart.
Above all, be true to yourself, and if you cannot put your heart in it, take yourself out of it. Follow your heart, but be quiet for a while first. Ask questions, and then feel the answer. Learn to trust your heart.
When work, 20 commitment, and pleasure unite to become one and you reach into that deep well where passion lives, nothing is impossible. Through the experience of devoted passion you will reap richer stores of knowledge than any text-book or course of study can give you.
