1. What is the main subject introduced in paragraph one?
It is the description of the effect of saying farewell to his parents, friends and folks on the author.
2. How is the story organized?
The story is chronologically organized (following the time sequence in which the event unfolded itself).
3. How did Weckerly feel before the day of his departure?
He felt eager and excited to wait for the day to come.
4. How did his mood change when the day had really come?
At the very beginning he became sentimental about saying good-bye to many people around him. Facing the reality of becoming independent, he began to feel afraid and uncertain .
5. What do you think about the ending of the story?
It is very impressive. Weckerly ends the story with a metaphor which catches the essence of the particular moment accurately. He compares himself to a rookie skydiver preparing for his first plunge, which leads to possible outcomes: sheer excitement or eventual death. The last sentence "He closes his eyes, takes a deep breath, and jumps" symbolizes the fact that from that day on the author jumps into the future of being independent no matter how long and complicated the road to it is.
What is the effect of saying farewell and actual leaving on the author?
Whom did the author like to say good-bye to? What was the author's mood like before the day of departure and after?
How did his mother's mood change during his brunch with her?
What was the significance of the particular day to the author?
Suggested Summary
The time of saying good-bye and actual leaving makes a great impact on the author, which is fully demonstrated in the opening sentence. He gives a general description of how he feels on that particular day, during which his own mood changes from sheer excitement for the prospect of becoming independent and free to fear and uncertainty to a mixture of both. By his brunching with Mom and saying good-bye to her, he makes a very smooth depiction of the change of his mother's mood from being chatty and cheerful at the beginning to being quiet, even somber as the final moment comes. To bring the story to its climax, the author ends the story with a symbolic description. He compares himself to a rookie skydiver preparing for his first plunge that leads to possible outcomes: sheer excitement or eventual death. No matter what will happen, he closes his eyes, takes a deep breath and jumps into the future.
Unit2 The New Economics of Oil
1. Why won't oil prices rise at all over the long time?
Firstly, because producers need the cash from oil too much to let their supply be interrupted for long. Secondly, and more important, because demand growth can't push prices upward as long as it is balanced by supply growth.
2. Why can't the members of the OPEC raise oil prices?
Because if they do, non-OPEC sources will grab market share by developing fields where technology has made production affordable.
3. Why have most majors cut their costs on oil?
Because technology lets the companies maintain healthy earnings at steadily lower oil prices.
4. Who takes a lead in the oil companies?
Those that master technology and efficiency, such as Shell, Exxon, and British Petroleum.
Should we worry about the oil price?
What is the main reason for oil price to fall?
Is Rainwater's high-price theory right?
What influences oil industry profits most?
How will lower oil price influence the world economy?
Suggested Summary
The article aims at establishing the idea that oil price will not rise even as demand soars. To begin with, the author shows the increasing consumption of oil around the world and the impact of technology on oil industry. By giving several examples, he draws the conclusion that the need for cash and dependence on technology leads to the fact that oil prices will even fall. Furthermore, technological updating, slashing the costs of finding, producing, and refining oil, is also a reason to support the author's point. There is evidence that technology lets the world companies maintain healthy earnings at lower oil prices. In conclusion, cheap oil accelerates the world economy, and a downside price scenario is increasingly likely.

Unit7 Competition Is Destructive
1. Why is competition destructive according to the author? (para. 3)
According to the author, competition is destructive because it undermines self-esteem, poisons relationships and holds us back from doing our best.
2. What are the purposes of the games devised or collected by Orlick and others? (para. 6)
The idea of the games devised or collected by Orlick and others is for each person on the field to make a specified contribution to the goal, or for all the players to reach a certain score, or for everyone to work with their partners against a time limit.
3. What is the difference between teamwork and team competition? (para. 8)
The difference between teamwork and team competition is that in teamwork everyone on the field is working together for a common goal, while in team competition a given player works with and is encouraged to feel warmly toward only half of those present.
4. Why do most kinds of fun require competition? (para. 10, 11, 12)
First of all, people don't know any other way or people have never tasted the alternative.
Secondly, we overlook the psychological costs of competition: it causes self-doubt and feelings of self-worth become dependent on external sources of evaluation.
5. Who is to blame for competition?
It is the structure of the game itself that is to blame rather than the individuals, since it sets competition at the very beginning.
Directions: Use the questions given below as a guide to write a summary. You can refer to Task 1 and Task 2.
What kind of games does the author use to illustrate the points?
What's the significance of changing an "opponent" into a "partner"?
What's the difference between teamwork and team competition?
What are the possible reasons that a large number of people insist that we can't do without win/lose activities?
What is the real problem?
Suggested Summary
By using the game of musical chairs, the author illustrates that competition is destructive not only in our daily work but also in entertainments. It is important and possible to change the form of the game by way of turning an opponent into a partner: Everyone on the field can work together for a common goal (teamwork) instead of competing with each other (team competition). Cooperative games and sports provide satisfaction and challenge without competition. The reason that a large number of people insist that we can't do without win/lose activities are that they don't know any other way and that they overlook the psychological costs of competition and the toxic effect of competition on our relations. Competition is not conducive to trust and it may lead one to look at others through narrowed eyes and even invite outright aggression. We are inclined to blame individuals for all this, but it is the structure of the game itself which causes competition. To solve the problem of competition, we need to be teaching our children how to enjoy themselves without competition.

Summarize the text.
What will be the main means to power our modern societies?
Why is it so urgent to find alternative energy?
What is the future of solar power, wind power and hydropower?
What are the final solutions to man's energy needs?
Suggested Summary
In the article "Power to the People", the author Mark Townsend states that solar power, wind turbines and other sources of clean power are now prepared to take the place of fossil fuels and become the main means to power our modern societies. He lists two reasons contributing to man's hot pursuit of alternative sources of energy. One is the environmental deficiencies of fossil fuels. Another is the crucial progress made by using new technology. According to the writer, a new generation of wafer-thin photovoltaic solar panels will lead to a great future of the solar energy. In addition, if the strength of rough seas can be brought under control, water power is likely to be another major renewable energy. Thirdly wind power can also benefit our life if we can eliminate the negative impacts on the environment. Finally, the author assumes that as an ideal clean energy, fuel cells will be the answer to the future energy needs.

Suggested Summary
By highlighting two technological crises, i.e. the swaying Millennium Bridge and the crippling Internet, the writer successfully draws the readers' attention to the somewhat embarrassing problems with some new high-tech innovations. The writer argues that these crises are inevitable because the innovations lead us into the unexplored world of science. With a look back on the establishment of the
Steamboat Act, the writer indicates that the improvement of any high-tech innovation will go through a long and slow process. Fortunately, we are now able to respond more quickly to the danger of new technologies, and have become increasingly skilled in controlling the crises. In the end, the writer claims with confidence that humans are certain to defeat any catastrophe, and will never stop exploring the unknown technical world.
