　　Many problems of modern society cannot be solved by laws and the legal system because moral behavior cannot be legislated.

　　現代社會的很多問題是法律和立法系統無法解決的，因為道德行為是無法用法律約束的。

　　The proposition asserts that the laws and the legal system cannot resolve many problems problem of the modern society since moral behavior cannot be legislated. In my point of view, I fundamentally agree with the speaker, as discussed below.

　　First of all, I concede that the laws and the legal system are essential to the modern society and they can resolve many problems. Common sense tells us that everyone has his own position and behavior, depending on their beliefs, experiences, knowledge, professions and emotional concern.However, we cannot simply let everyone do everything that he or she wants, since this will lead to mess and may harm the stability of the society. Thus, the government has to announce the laws and build a just legal system to restrict the citizens. Only by doing this, can the society get to a balance and harmonious status? For instance, the industrial factories want to expel the polluted water into the river without making it clean. If there is not a law or a legal system to restrict the factories from expelling the polluted water, the poisoned water may get into the river, even the sea. This will be really harmful. It may firstly kill the animals living in the river, it may also further harm the human beings if they have drunk the water or eaten the polluted fish. It may bring damage to the environment as well. Considering this, we have to establish laws to prevent the factories from expelling polluted water and other detriments. From this case, we can see how important laws and legal systems are.

　　However, we have to admit that the laws and the legal systems cannot resolve many problems in the modern society as well, such as the usage of euthanasia, the homosexual marriage. When the Watson and Crick found the double-helix structure of the gene and the scientists further found the way to clone. It brings many social problems that the laws and legal systems cannot resolve. Should the scientists clone human beings? If yes, then what is the relationship between the two? Do the cloned people have the same right with the other human being or even whether they are human beings or not? Though the legal systems in many countries ban the scientists from cloning people, some scientists still do this secretly. All these questions cannot simply be resolved by the laws as it is related to the morality.

　　Additionally, the laws can not involve the moral behavior. If the laws consider the moral behaviors too much, it will lose justice. Nevertheless, only considering the laws without morals may cause mistake. For instance, in India, their law is statutes given by the government and the judge can only his judges on the bases of the existing laws. Once, a mother in India killed her son,who is a murderer and did lots of bad things. The police in India tried to catch him for years without any result. He committed so many crimes that even death cannot atone for the offence.His mother knows that her son will kill many more people if she does not kill him. Thus, when her son came back to see her one day, she killed him with the poison. In this case, to kill the mother is probably not the best choice, since this may make people think that being just is wrong. But according to the present law, the judger had to sentenced the mother to death, and this brought a widely debate thought out the country.

　　Further, only the morality can make people to understand what is right and what is wrong, and to restrict people with morality will be a good way. Under the pressure of laws and legal systems,many people just do the bad thing secretly because they do not know that they are wrong. And many people may even think that the laws are wrong and disobey or even resist the law. They may commit crimes again after they are punished. Only when a people have known the morality and find the right measurement to distinguish right and wrong, they can find their mistakes and become a better person. A statistics involving many prisons in China find that the prisoners who learn morality and know their mistakes have a much lower rate of committing crime again.

　　In the final analysis, we can see that the laws and legal system cannot resolve all the problems in the society and therefore we should agree with the author.
