▆ 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

▆Sample Essay for Task 2:
Thinking positively means allowing your mindto be filled with optimistic feelings, and alwayshoping for the best though still aware of thedifficulties that might be involved.
The human mind is powerful; thoughts ofoptimism and pessimism can be a self-fulfillingprophecy. Though it might seem impossible tosome, positive thinking and success actually havea cause-and-result relationship. The reason isthat a person with positive thinking will alwaysbroadcast goodwill and confidence and that kindof radiating attitude will take a hold on everybody.
Gradually, people’s attitude will shift towards moretrust and respect. This not only opens up moreopportunities for the individual, but it also feedsback emotionally, and the cycle continues.
Though the shaping of a positive or negativepersonality often happens subconsciously, it ispossible to control such processes consciously. Aperson can try visualizing favourable situations,whether it is remembering a contest won as achild or imagining getting that job offer so longsought after. Over time
circumstances will changeaccordingly. (169 words)
