1. Dose weather affect people?
就本题而言，如果仅说明rainy-sad或者sunny-happy等诸如此类的感受，似乎过于简单，若能从天气对人们生活习惯、性格等个方面的影响着手则会使回答显得更具深度。

Candidate 1: On one hand, weather affects us externally. Let me set an example. In rainy days, we have to umbrellas or raincoats outdoors; we also have to take precautions against cold. Likewise, windy, snowy or sunny days can also affect us. On the other hand, weather may have an effect on our psychology. I am a person whose feelings sometimes can be influenced by the weather. Overcast(多云的) days can cast a gloom over(使笼罩上一层忧郁的情绪) me; sunny days can make me at ease; snowy days can make me feel sober(清醒的，冷静的).

Candidate 2: Weather affects both our life and our mood. Good weather, say, sunny or warm days, makes us fell comfortable, and we'll be more likely to take part in various activities, such as hiking, swimming, fishing or taking a tour of the city. We have a good time and taste the quality of life. As the saying goes, smile will make one ten years young. Be happy, enjoy longevity(长寿). On the contrary, bad weather often makes us negative and depressed. We don't want to do anything. Nowadays, because of human's destruction to the environment, weather becomes changeable and extreme hot or cold which is not uncommon. EI Nino and La Nina phenomena arise, and more storms, sandstorms, etc. occur,which not only have impact on our lives, but on globe economy. To live a better and healthier life, we must learn to be in harmony with environment.

Candidate 3: Weather can affect many things. Besides the growth of corn and the quality of air, it can also affect human emotions. Different weather conditions may provide different backgrounds for various stories. The rapid changes of clothes due to changeable weather, for example, an unexpected fever as tempreture decreases, may affect people's moods to a large extent. As for me, I prefer a clear day with warm sunshine and tasty breeze. In contrast, I'll feel extremely anxious in a windy or rainy day. The heavier the wind or the rain is, the worse my mood will be. It is evident that I have to pay so much attention to prevent the wind or the train is, the worse my mood will be. It is evident that I have to pay so much attention to prevent the wind or the rain from blowing my things away or wetting my books in hand that I have no time to appreciate the scenery around, feeling tense and irritable. What is worse is that the weather in recent years seems to be increasingly changeable and a spell of(某事物持续的一段时间) sudden rain, heavy wind is becoming common in our daily life. In my view, this is another symbol of the bad tendency of weather change besides the increasing number of worldwide disasters. Being affected by weather every day, we have to take immediate measure to protect our environment.

三个答题者的论证都非常严密，令人信服。Candidate 1从外在因素和内心感受两方面入手（on one hand/on the other hand），描述了天气对自身的影响；Candidate 2和Candidate 3不仅叙述了人们的心情、业余活动会因不同天气状况而变化，更突出了人与环境的和谐相处及保护环境的重要性，深化了主题。
