Unit 4 Nathaniel Hawthorne
:1.Why is the prison the setting of Chapter 1 ?
No matter how optimistic the founders of new colonies may be, they are quick to establish a prison and a cemetery in their “Utopia,” for they know that misbehavior, evil, and death are unavoidable.
This belief fits into the larger Puritan doctrine, which puts heavy emphasis on the idea of original sin—the notion that all people are born sinners because of the initial transgressions of Adam and Eve in the Garden of Eden. he is therefore using the prison building to represent the crime and the punishment which are aspect of civilized life. What is the implication of the description of the roses?The rosebush symbolizes the ability of nature to endure and outlast man's activities. The narrator suggests that roses offer a reminder of Nature's kindness to the condemned; for his tale, he sa ys, it will provide either a “sweet moral blossom” or else some relief in the face of unrelenting sorrow and gloom.
2.Describe the appearance of Hester Prynne and the attitude of the people towards her.
The second paragraph on page 30.The crowd in front of the jail is a mixture of men and women, all maintaining severe looks of disapproval. Several of the women begin to discuss Hester Prynne, and they soon vow that Hester would not have received such a light sentence for her crime if they had been the judges. One woman, the ugliest of the group, goes so far as to advocate death
for Hester.
3.What has happened to Hester? As a young woman, Hester married an elderly scholar, Chillingworth, who sent her ahead to America to live. While waiting for him, she had an affair with a Puritan minister named Dimmesdale, after which she gave birth to Pearl. The scarlet letter is her punishment for her sin and her secrecy. Why does she make the embroidery of the letter A so elaborate?
It seems to declare that she is proud, rather than ashamed, of her sin. In reality, however, Hester simply accepts the “sin” and its symbol as part of herself, just as she accepts her child. And although she can hardly believe her present “realities,” she takes them as they are rather than resisting them or trying to atone for them. How does this tell us about her character? Throughout The Scarlet Letter Hester is portrayed as an intelligent, capable. It is the extraordinary circumstances shaping her that make her such an important figure.
Unit 6 Henry David Thoreau
1. Where indeed did Thoreau live, both at a physical level and at a spiritual level? He lived in a cabin on Walden Pond, which belonged t o Emerson’s property.
2.Had Thoreau ever bought a farm? Why did he enjoy the act of buying? No, he h adn’t. He avoided purchasing a farm because it would inevitably tie him down financially and complicate his life. Thoreau didn’t see the acquisition of wealth as the goal for human existence, he saw the goal of life to be an exploration of the mind and of the magnificent world around us. He regarded the places as an existence free of obligations and full of leisure.
3. Is it significant that Thoreau mentioned the Fourth of July as the day on which he began to stay in the woods? Why?
Yes, it is. Because The Fourth of July is known as Independence Day, the birthday of the United States. Here Thoreau uses the day to express his beginning of regeneration at Walden. It also means a symbol of his conquest of being.

Unit8 mark twain
Questions1: Why do you think Mr. Wheeler is so eager to tell these stories?
From Mr. Wheeler’s behaviors and contents of his narration. First, when "I" asked him to tell "me" something about W. Smiley, he “backed me into a corner and blockaded me with his chair, and then sat down and reeled off the narrative”. And during the process of telling his stories, he never paid any attention to others' response to his story and just went on telling what amused him. At last when the listener felt boring and wanted to leave, Mr. Wheeler even didn't notice it and still asked him to sit there listening to him.
Question2: Does his audience share his enthusiasm in telling the stories?
No. the audience does not show any interest in Mr. Wheeler’ stories. In fact, the narrator was very feverish about his stories, but, in the eyes of the listener, the stories were very boring and had nothing to do with his preoccupation. As an educated man, the listener couldn't understand the way of laborers for joy, and he would never bother himself to understand it. So after the longtime of Mr. Wheeler’ solo narration and when the audience got a chance, he fled away. Question3: Do you think the narrator and his listener ever suspect the presence of humor? Why? How do you interpret their interactions?
The narrator and his listener never noticed or suspected the presence of humor. During the intercourse, the narrator went vigorously on his monotonous narrative "without a little smiling" talking about the animals and the things like, while the listener felt rather puzzled or bothered by his stories. It seemed to be kind of coarse things. So the two different scenes go on separately without an intersection. And their interaction was a complete failure according tour common sense about communication. But it in this sense produced the effect of humor which can be tasted by our readers due to the skills adopted by Mark Twain .
Unit14 The Great Gatsby
Do you think G atsby deserv es to be called “the great”?
Why?
(1)I think it is too complicated to simply say Gatsby
deserves to be ―great‖or not.For one thing, Gatsby was
ambitious, hardworking, generous and passionate. He was so
extremely loyal to his love and Daisy that he could do
anything to get Daisy back. In this respect, he is
much ―greater‖ than his contemporaries. For another thing,
Gatsby never realized that Daisy wasn’t the girl he loved
anymore. Gatsby was so innocent that he staked everything
on his dreams, not realizing that his dreams are unworthy of
him. He wasn’t sober enough to be great. 2.Does “the green
light” Gatsby believed in exist in reality? Why or
why not ?
(1)I think ―the green light‖does not exist in reality.
Because the green light which situated at th e end of Daisy’s
East Egg dock and barely visible from West Egg lawn
represents Gatsby’s unattainable dream. Although the color
itself can be seen as hope and bright future, Gatsby’s quest
for Daisy back is doomed to be impossible. Daisy lived
in ―a materi al world without being real, where poor ghosts,
breathing dream like air‖. The distinction between ideal and
reality was huge. As if American dream between golden past
and golden future always suffered from the realistic betrayal
and crush.
3.What does Gats by’s Schedule reveal about him and how
does it relate to the American Dream?
(1)The schedule is a reflection of Gatsby’s determination
and ambition. It reveals that he is hard on himself in pursuit
of his goal—to be an upper-class man.
(2)On one hand, we can know that he is persistent in
pursuing his American Dream-- to attain wealth and
happiness through his struggle. On the other hand, he is too
idealistic and naive. The girl he loves is as vulgar and
superficial as others in her circle, she is unable to meets
Gatsby’s romantic fantasy. So his dream is destined to shatter,
which indicates the disillusion of American Dream. 4.When
you read the line “He (the man with owl-eyed glasses)
took off his glasses and wiped them again, outside and
in ,” what images does it create in your mind, given the
novel’s numerous references to the strikingly strange
scene of the spectacled eyes?
(1)From this line , superficially, owl-eyes is a person with thick and blurry glasses who can not see clearly all the things in the world. However, we know he is actually an owl-wise observer and sees more clearly than anyone else in the novel. Owl-Eyes, except Nick, is the only friend to appear at the rain-soaked burial of Gatsby, when others are unwilling to come. He feels sympathy for Gat sby’s tragedy.
Unit 16 Ernest Hemingway
1.How do you interpret the irony of the title after reading
the story?
(1)The title ―A Clean Well-Lighted Place‖ refers to the
caféin the text. The caféwas very clean and well- lighted.
From the literary meaning, we may feel this place was very
warm and comfortable, was a place where people need
warmth wanted to go. So the old man, who was rich but
deaf and lonely came here to find warmth and avoided nada.
It was the only place he could go and could find some
comfort.(2)However, the younger waiter was very selfish.
Therefore, he refused to offer the old man another cup of
wine by the excuse that the business was finished. This café
should be warm but the younger waiter forced the lonely and
deaf to leave without any sympathy. This is the irony of the
title.
2.Do you think youth and confidence can help one
withstand the metaphorical dark?Why or why not?
(1)I don’t think so.In our opinion, the m etaphorical dark
means nada,nothing in one’s inner heart. In the article, the younger waiter had both youth and confidence; however, he never made full use of them. As we can see, he didn’t understand the old man’s suicide and excessive drinking, and failed to see his tomorrow through the old man’s present situation.
3.The older wait er said to the younger waiter:“We are of two different kinds.” In what way do you think they are different?
(1)I think they are different from each other in the following four aspects:In the beginning, they are in different ages.The older waiter was in his middle age; while the other was much younger.
(2)Then, they have different attitudes towards the old man. From the article, the older waiter could understand the old man and show sympathy to him. However, the young man was very selfish. He showed hatred rather than sympathy to the old man.
(3)Next, they have different attitudes towards life. The older waiter had a deep sense of life. He was brave and wanted to fight again nada. Besides, he cared about others. he has a shadow understanding of life. He satisfied with his present love and work, he only care about himself. He even never thought of his future.
(4)Finally, they have different attitudes towards nada. The older waiter had realized that it is impossible to avoid nada in one’s whole life. The only thing h e can do is to keep a kind of clearness in his own mind. But out of youth and confidence, he failed to overcome nada. On the contrary, the younger waiter had the two most important factors for withstanding nada; however, he didn’t realize the nada in his heart at all. Then his youth a nd confidence became useless.
Unit 17 20th -Century American Poets
1.Ezra Pound In A Station of the Metro
1.Why does the poet call the faces of pedestrians "apparition"?These pedestrians are all walking in a hurry amidst the drizzling rain. What do "petals" and "bough" stand for? Petals refer to the faces while the bough stands for the floating crowd.
2.Wallace Stevens Anecdote of the Jar
1.What does the jar in poem symbolize? Why does the speaker place it on top of a hill?The jar here symbolizes a certain perspective on looking at this world. If the perspective of the viewing is
creative and unique, it will change the conventional order of the old world. When a new perspective comes out, it will certainly hold attention from the rest.
2. The jar is "round" and "of a port in air," meaning that it has a stately importance. What effect does it have on surroundings when placed on the ground? Maybe the round jar assumes the air of a domineering figure, which helps to form a certain order out of the disordered surrounding.
3. How did the wilderness of Tennessee characterized? What words or phrases does the poet use to describe it?Tennessee seems to a place full of life and energy. “Slovenly,” “sprawl” and “wild” are some of the words used to describe the place. (See Anecdote of the Jar ) 3.Robert Frost
(1)Fire and Ice 1. What are the symbolic meanings of fire in this poem? Fire symbolizes natural disaster, human passion, as well as war. 2. Why does the speaker say that ice is also great for destruction? Explain what ice stands for here. Ice, oppose to fire, is also a dreadful natural disaster in this world, and ice is always related to indifference, coldness, hatred, and the other negative sentiments of human beings. 3. What is your opinion about fire and ice? Which one is more destructive? Both fire and ice can destroy this beautiful world if they are beyond control of human beings. Therefore we should be open-minded and reduce our prejudice and pride so as to keep this world in peace.
(2)Stopping By Woods On a Snowy Evening 1. In your opinion, what was the reason that made the speaker stop by the woods on a snowy evening? The poet was deeply attracted by the natural beauty of the scene at that very moment. 2. Why did the horse give the harness bell a shake? The horse grew impatient by stopping in the middle of the dark, cold woods at midnight. It was eager to go home.
3. Why couldn't the speaker stay longer by the woods to appreciate its mysterious beauty? He realized that it was late at night and he would have to hurry home to get some food and sleep, because the next morning he would have a lot of work to do.
4. What is the effect of repetition in the last two lines? The refrain-like repetition in the last two lines reminds the reader a simple fact of life: whatever happens, one must go forward in the journey of his or her life.
(3) The Road Not Taken 1. What is the speaker's initial response to the divergence of the two roads? The speaker is at a loss which road he should choose, and he feels sorry that he cannot explore both roads at the same time. 2. Describe the similarities and differences of these two roads. Which one does the speaker take?Two roads are similar except one of them is more “grassy,” which impl ies that it is less traveled by people. The speaker prefers the less traveled one, because he likes adventure. 3. What might the two roads stand for in the speaker's mind? One road stands for the traditional one and the other is unconventional one and full of challenges and difficulties. To follow other people's footsteps or to open a new road for himself is really not an easy decision for us to make in our lives.

《微观经济学》（高鸿业第四版）第三章练习题参考答案 1、已知一件衬衫的价格为 80元，一份肯德鸡快餐的价格为 20 元，在某 消费者关于这两种商品的效用最大化的均衡点上， 一份肯德 鸡快餐对衬衫的边际替代率 MRS 是多少？ 解：按照两商品的边际替代率 MRS 的定义公式，可以将一份肯德 鸡快餐对衬衫的边际替代率写成：MRS XY 其中:X 表示肯德鸡快餐的份数;Y 表示衬衫的件数；MRS 表示 在该消费者实现关于这两件商品的效用最大化时，在均衡点上 有 MRS xy =P x /P y 即有 MRS =20/80=0.25 它表明：在效用最大化的均衡点上，消费者关于一份肯德鸡快 餐对衬衫的边际替代率 MRS 为0.25。 2假设某消费者的均衡如图 1-9所示。其中，横轴OX 1和纵轴 0X 2，分别表示商品1和商品2的数量，线段AB 为消费者的预算线， 曲线U 为消费者的无差异曲线，E 点为效用最大化的均衡点。已知商 品1的价格R=2元。 在维持效用水平不变的前提下 要放弃的衬衫消费数量。 消费者增加一份肯德鸡快餐时所需
(1)求消费者的收入； (2)求商品的价格P2; ⑶写出预算线的方程； (4) 求预算线的斜率； X1 (5) 求E点的MRS12的值 解：(1)图中的横截距表示消费者的收入全部购买商品1的数量 为30单位，且已知P1=2元，所以，消费者的收入M=2元X 30=60。 (2)图中的纵截距表示消费者的收入全部购买商品2的数量为20单位，且由(1)已知收入M=60元，所以，商品2的价格P2斜率二—P1/P2二— 2/3，得F2=M/20=3 元 (3)由于预算线的一般形式为： P1X+PX2二M 所以，由(1)、(2)可将预算线方程具体写为2X+3X=60。 (4)将(3)中的预算线方程进一步整理为X2=-2/3 X 1+20。很清楚， 预算线的斜率为—2/3。 (5)在消费者效用最大化的均衡点E上，有MRS二=MRS二P1/P2, 即无差异曲线的斜率的绝对值即MR勞于预算线的斜率绝对值P1/P2。因此， 在MRS二P/P2 = 2/3。 3请画出以下各位消费者对两种商品(咖啡和热茶)的无差异曲 线，同时请对(2)和(3)分别写出消费者B和消费者C的效用函数。
