People with different interests and personalities cannot be friends.
Opposites attract each other, as with magnetic fields. This is because people always think their opposites have something they regard as missing in themselves. Hence, they are open to befriending someone who is less similar to them, with interests and personalities difference on the back burner. For instance,scientists have different areas of interest from dancers, but they might still be drawn to a dancer, so American dancer Loie Fuller’s scientist friends do. Furthermore, great friendship is more likely to work out between opposites. For example, a pair of twins may not be like two peas in a pod when it comes to personal traits---one is noisy and lively while the other is introvert,but they always enjoy mutual company exclusively and become extremely close friend to the extent that nobody else can take the place of each other in
later life. (143)
Also,one gets more out of life to seek friendship from a different group. In online social network such as Twitter and Facebook, people join groups based on their likes or interests. Similarly, in day-to-day life, people with similar hobbies and personalities always gather in the same circle. Nonetheless, similarity sometimes might be more a stumbling block than opportunity in term of personal growth or achievement, compared with difference. For example, a young musician has not hit big even though he has acquaintances, partners, or keeps making new friends in music community, where everyone loves music like him. However, to everyone’s great surprise, he rises to fame overnight as an actor after befriends a filmmaker, who may know little of music but enlighten the young man about how to act. Therefore, one could be exposed to new potentials and possibilities in proximity to people with other hobbies or qualities. (145)
Agree or disagree: Only effective way for government to encourage energy conservation is to increase price of gasoline and electricity.
这是822托福考试的题目，明显是一道”政策类”的题目，分析题目得知主体为政府，目的是鼓励能源的节约，政策是提高汽油和电的价格，限定条件是Only effective way。由于有这一限定条件存在，其实完成这个题目有多种方法，第一种写法如下：
1.It seems reasonable to simply enhance the price of gasoline and electricity to pass the recognition of energy conservation to the public, as under the implementation of such policy the same amount of money would fetch a reduced number of energy to use. However, the real situation is much more complex, and the proposed strategy would probably not be effective as expected and adversely may result in negative consequence.
2.As the most widely used formats of energies in current days, the usage of gasoline and electricity would not get reduced even the price is highly promoted by the government. 这段可以分别写这两种能源的使用问题，比如油价上升了，汽车制造商为了汽车还能卖出去就会削减汽车的价格，从而可能有更多的人去买车，所以对汽油的消耗反而没有下降; 电的使用不仅跟人们的生活息息相关，也和生产相关, 增长电费会降低生产量从而影响经济，所以这个其实是难以实现的，一点也不effective。
3.To ensure both an unchanged life style and stable costs on energy, people may tend to use the resources of the public and institutes, which may even waste more energy instead of conserving it, going inversely towards the aim of the proposed policy. 开公家车，加公家油，用公家电等等，你们懂的。
1.The proposed policy would be efficacious, since when people realize they need to spend more on fetching the same amount of energy, they would reduced the usage of such necessity to ensure a stable living cost. 这段写政策有效。
2.Popularization towards the enhancement of people’s awareness should also be considered and implemented by the government for resolving the energy waste issue at the source. 宣传提高人们的意识。
3.It is necessary for government to invest more projects which are relevant to both the enhancement of energy usage efficiency and exploration of new types of energy. 投资做研究提高能源使用效率，开发新能源。
