Intelligence-Nature or Nurture
Are some people born clever, and others born stupid Or is intelligence developed by our environment or experience Strangely enough, the answer to both questions is yes。
On the one hand, if we take two people at random from the crowd, it is very likely that their degrees of intelligence will be completely different. However, if we take two identical twins, chances are that they will be as intelligent as each other. Therefore, a conclusion can be drawn that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence。
On the other hand, though, if we put two identical twins in different environments, for example, we might send one to university and the other to a factory where the work is boring, we would find differences in their intelligence several years later, which indicates that environment does play a crucial role in our intelligence。
Just as every coin has two sides, our intelligence is partly born and partly developed. The sure way to develop our intelligence is intelligent parents as well as a good environment.
Private cars have become an important aspect of people's life in many parts of our country, especially in large cities such as Beijing, Shanghai and Guangzhou. While they bring much convenience to people, they are also widely criticized. There are some arguments for owning private cars. In the first place, cars allow people to move around freely, which greatly improves our living standard. We can easily drive cars for sightseeing on weekends. In the second place, cars are a comfortable way to travel, especially in bad weather. Last but not least, the car industry can boost economy by creating many job opportunities in production of steel, rubber, glass and so on. However, there are also many good arguments against cars. First of all, they pollute the environment by emitting harmful gases and giving out loud noises. In addition, cars cause a large number of traffic accidents, which bring great misery to the victims' families. As far as I am concerned, we should limit the number of private cars by providing better mass transportation and better service for the people. Everyone should sacrifice his or her own interest for the common good of the society.
