The following hints mightserve as a guide:a. The problems existing in the relationships between people in our society.b. The negative results such problems may bring about to our society.c. What can you do to help establish a harmonious society as a student?▆Sample Essay for Task 1:One weekend morning, while walking on a bustling street with a light heart, I was suddenly overtaken by a startling moan. Turning around, I discovered the sound was coming from a black mass in a corner. “What’s that?” My heart pounded heavily. I went up and saw a human being, alive but in a dreadful state. He was crouching on the ground with deformed hands and legs, mumbling something. He had obviously lost the normal ability to move and work. A dirty plate was placed in front the miserable-looking man, in which there were some coins and small notes.As my eyes were drifting away from him, his eyes caught mine suddenly. What eyes they were! Filled with misery and expectation, they were looking straight at me. He was unable to speak, but I seemed to hearhis pleading voice and read his despairing mind. His look seemed to be telling me about his hard life and his longing for help. For a while, I was at a loss what to do. Should I drop some coins in the plate like some other passers-by or turn away in indifference? I recalled news reports about men pretending to be beggars, who were actually healthy and able to work. Could this be another one of those scams? But the beggar was there, groaning and living. Then something seemed to hit me hard. I drew a five-yuan note from my pocket, droppedit in his dirty plate and walked away quickly in silence.“No good deed is too small.” Maybe we need to bear this saying in mind.▆Sample Essay for Task 2:We are living in a world of distrust. We live behind cold security bars; we do not talk to strangers, let alone go out of our way to help them; we live in fear of fake products. In short, fear and feelings of insecurity fill the environment we live in.All this greatly harms our society. Growing up in such an environment, we tend to feel isolated and care only about ourselves. If things go on like this, ‘trust’, ‘teamwork’, and ‘harmony’ will eventually become terms unheard of.In my opinion, trusting others and being trustworthy are the two basic principles that we should follow if we want to improve human relationships. We may not be in a position to change others, but we can change the way others see us by winning their trust in us. Mutual understanding and love are the pillars that support a harmonious society.Unit TwoOptimism and Positive ThinkingEnhance Your Language AwarenessWords in Action▆Working with Words and Expressions3.In the box below are some of the words you have learned in this unit.

You may draw on some useful ideas and expressions from a variety of sources, such as the two texts in this unit or the Internet.1) Having read the two passages in this unit, you may have come to a better understanding of life and thetimes when pessimistic and optimistic thoughts take turns to affect your behaviour. Write a letter of encouragement (of about 150 words) to one of your high school friends who failed in the college entrance examination. Tell him or her about your new understanding of the need to remain optimistic.2) The writers of the two texts in this unit convey to us the message that we need to look at the positive side ofanything that comes to us and that we need to take an optimistic and positive attitude toward life. Write an essay (of about 150 words) to share your ideas with your classmates. The following hints may be of some help:a. What is meant by “thinking positively”?b. What is the connection between success and optimism?c. How can we keep an optimistic and positive attitude?▆Sample Letter for Task 1:Dear Weihua,I know you are still feeling upset about your results in the college entrance examination. I’ve just read an article about how pessimistic and optimistic thoughts can affect our behaviour and I’m now sending you a copy, hoping that it will help you step out of the shadows.Naturally, failing the college entrance examination can be very depressing, yet if you continue to dwell on the past, you will never be able to pick yourself up and focus on what is more important for now and the future. Life is full of trials and anyone may suffer setbacks. We must take an optimistic attitude towards the things we have to deal with. Optimism and positive thinking are powerful forces. Good things do come true if we picture them often. Please do have confidence in your potential. Just work hard and prepare for another chance.You will make it.Yours,Janet(152 words)▆Sample Essay for Task 2:Thinking positively means allowing your mind to be filled with optimistic feelings, and always hoping for the best though still aware of the difficulties that might be involved.The human mind is powerful; thoughts of optimism and pessimism can be a self-fulfilling prophecy. Though it might seem impossible to some, positive thinking and success actually have a cause-and-result relationship. The reason is that a person with positive thinking will always broadcast goodwill and confidence and that kind of radiating attitude will take a hold on everybody.Gradually, people’s attitude will shift towards more trust and respect. This not only opens up more opportunities for the individual, but it also feeds back emotionally, and the cycle continues.Though the shaping of a positive or negative personality often happens subconsciously, it is possible to control such processes consciously. A person can try visualizing favourable situations, whether it is remembering a contest won as a child or imagining getting that job offer so long sought after. Over time circumstances will change accordingly.

Theme-Related Writing1) Write a narrative essay (of about 150 words) about your pursuit of a dream or someone’s experiences inmaking his / her dream come true.Sample essayLi Hui, my friend in high school, was born into a worker’s family. She began to dream of becoming a cartoon artist from her childhood. To her disappointment, her parents strongly opposed her career choice, because the cost of her education would be too high for the poor family, and they were worried about the job opportunities for a cartoon artist. However, Li Hui would not change her mind. She worked hard to perfect her skills and searched persistently for ways to realise her dream. Just before she finished high school, the chance came: a famous art school was holding a cartoon drawing competition. The first three winners would be given a scholarship to study cartoon drawing at the school. Li Hui told herself not to let the chance slip through her fingers. She readily participated and won the second place. She is now studying there and I feel certain that her dream will come true. (156 words)2) People may have different opinions about the key factors for success. Write a short essay (of about 150words) and share your opinions with your classmates.Sample essay:In my opinion, before a person becomes successful, he or she should fully understand the basic elements of success: competence, determination and optimism.For a person to succeed, he or she has to face great competition and excel in his or her chosen career. The person needs to demonstrate and prove his or her competence in dealing with problems. Without competence, the person can neither stand out among the crowd nor attract the attention of those who hold the keys to the doors of opportunity and advancement.Yet ability alone cannot guarantee success. Often enough, things do not go the way we have planned and failure is unavoidable no matter how intelligent or capable we may be. In such cases one needs to remain firm and optimistic, always believing that hard work will eventually pay off. If the person gives up halfway, success will never knock at the door.

The followinghints might serve as a guide:a. The problems existing in the relationships between people in our society.b. The negative results such problems may bring about to our society.c. What can you do to help establish a harmonious society as a student?▆Sample Essay for Task 1:One weekend morning, while walking on a bustling street with a light heart, I was suddenly overtaken by a startling moan. Turning around, I discovered the sound was coming from a black mass in a corner. “What’s that?” My heart pounded heavily. I went up an d saw a human being,alive but in a dreadful state. He was crouching on the ground with deformed hands and legs, mumbling something. He had obviously lost the normal ability to move and work. A dirty platewas placed in front the miserable-looking man, in which there were some coins and small notes.As my eyes were drifting away from him, his eyes caught mine suddenly. What eyes they were! Filled with misery and expectation, they were looking straight at me. He was unable to speak,but I seemed to hear his pleading voice and read his despairing mind. His look seemed to be telling me about his hard life and his longing for help. For a while, I was at a loss whatto do. Should I drop some coins in the plate like some other passers-by or turn away in indifference? I recalled news reports about men pretending to be beggars, who were actually healthy and able to work. Could this be another one of those scams? But the beggar was there, groaning and living. Then something seemed to hit me hard. I drew a five-yuan note from my pocket, dropped it in his dirty plate and walked away quickly in silence.“No good deed is too small.” Maybe we need to bear this saying in mind.▆Sample Essay for Task 2:We are living in a world of distrust. We live behind cold security bars; we do not talk to strangers, let alone go out of our way to help them; we live in fear of fake products. In short, fear and feelings of insecurity fill the environment we live in.All this greatly harms our society. Growing up in such an environment, we tend to feel isolated and care only about ourselves. If things go on like this, ‘trust’, ‘teamwork’, and ‘harmony’ will eventually become terms unheard of.In my opinion, trusting others and being trustworthy are the two basic principles that we should follow if we want to improve human relationships. We may not be in a position to change others, but we can change the way others see us by winning their trust in us. Mutual understanding and love are the pillars that support a harmonious society.Unit TwoOptimism and Positive ThinkingEnhance Your Language AwarenessWords in Action▆ Working with Words and Expressions3.In the box below are some of the words you have learned in this unit.

You may draw on some useful ideas and expressions from a variety of sources, such as the two texts in this unit or the Internet.1) Having read the two passages in this unit, you may have come to a better understandingof life and the times when pessimistic and optimistic thoughts take turns to affect your behaviour. Write a letter of encouragement (of about 150 words) to one of your high school friends who failed in the college entrance examination. Tell him or her about your new understanding of the need to remain optimistic.2) The writers of the two texts in this unit convey to us the message that we need to lookat the positive side of anything that comes to us and that we need to take an optimistic and positive attitude toward life. Write an essay (of about 150 words) to share your ideas with your classmates. The following hints may be of some help:a. What is meant by “thinking positively”?b. What is the connection between success and optimism?c. How can we keep an optimistic and positive attitude?▆ Sample Letter for Task 1:Dear Weihua,I know you are still feeling upset about your results in the college entrance examination. I’ve just read an article about how pessimistic and optimistic thoughts can affect our behaviour and I’m now sending you a copy, hoping that it will help you step out of the shadows.Naturally, failing the college entrance examination can be very depressing, yet if you continue to dwell on the past, you will never be able to pick yourself up and focus on what is more important for now and the future. Life is full of trials and anyone may suffer setbacks. We must take an optimistic attitude towards the things we have to deal with. Optimism and positive thinking are powerful forces. Good things do come true if we picture them often. Please do have confidence in your potential. Just work hard and prepare for another chance.You will make it.Yours,Janet(152 words)▆Sample Essay for Task 2:Thinking positively means allowing your mind to be filled with optimistic feelings, and always hoping for the best though still aware of the difficulties that might be involved.The human mind is powerful; thoughts of optimism and pessimism can be a self-fulfilling prophecy. Though it might seem impossible to some, positive thinking and success actually have a cause-and-result relationship. The reason is that a person with positive thinking will always broadcast goodwill and confidence and that kind of radiating attitude will take a hold on everybody.Gradually, people’s attitude will shift towards more trust and respect. This not only opens up more opportunities for the individual, but it also feeds back emotionally, and the cycle continues.Though the shaping of a positive or negative personality often happens subconsciously, it is possible to control such processes consciously. A person can try visualizing favourable situations, whether it is remembering a contest won as a child or imagining getting that job offer so long sought after. Over time circumstances will change accordingly.

She began to dream of becoming a cartoon artist from her childhood. To her disappointment, her parents strongly opposed her career choice, because the cost of her education would be too high for the poor family, and they were worried about the job opportunities for a cartoon artist. However, Li Hui would not change her mind. She worked hard to perfect her skills and searched persistently for ways to realise her dream. Just before she finished high school, the chance came: a famous art school was holding a cartoon drawing competition. The first three winners would be given a scholarship to study cartoon drawing at the school. Li Hui told herself not to let the chanceslip through her fingers. She readily participated and won the second place. She is now studying there and I feel certain that her dream will come true. (156 words)2) People may have different opinions about the key factors for success. Write a short essay(of about 150 words) and share your opinions with your classmates.Sample essay:In my opinion, before a person becomes successful, he or she should fully understand the basic elements of success: competence, determination and optimism.For a person to succeed, he or she has to face great competition and excel in his or her chosen career. The person needs to demonstrate and prove his or her competence in dealing with problems. Without competence, the person can neither stand out among the crowd nor attract the attention of those who hold the keys to the doors of opportunity and advancement.Yet ability alone cannot guarantee success. Often enough, things do not go the way we have planned and failure is unavoidable no matter how intelligent or capable we may be. In such cases one needs to remain firm and optimistic, always believing that hard work will eventually pay off. If the person gives up halfway, success will never knock at the door.
