1. Smoking should be banned in public places Many surveys, studies and scientific research has proved that smoking and second-hand smoking is harmful to our health. Thus, I think it's necessary to ban smoking in public places. Here are my reasons. First of all, smoking pollutes the environment. When a person smokes, it releases plenty of carbon dioxide to the air, which not only polluting the environment but also harm the people around. Secondly, it is greatly harmful to people not only physically but also mentally. One survey showed that smokers are easier to suffer from various diseases such as lung cancer and lung cancer than non-smokers. Cigarette contains plenty of nicotine which can destroy the immune system of human beings. Once the immune system is weakened, people are easy to fall ill. Moreover, smokers are easy to get addicted and can not control themselves. Also, there are two types of smokers, active and passive. The person who smokes is active and other who are near him and inhale the smoke are passive smokers. Both are equally affected by the ill effects of smoking. Smokers and non-smokers meet at many public places like offices, restaurants, hotels and so on. This makes it possible for smokers to pass on second-hand smoke to non-smokers. Therefore, to be fair to non-smokers and to protect our environment, I strongly agree that smoking should be banned in public places. 2. Academic qualification ensures success in life. I agree with this point for the following reasons. First, academic qualification ensures you have the basics in learning. If your basic grounding in math, science, and language is strong, your chances to success may increases a lot than those who do not have academic qualifications. Mastering these subjects allows you to calculate, to innovate and to communicate. These essentials for success cannot be learned without professional help in schools and colleges. Second, if you look at a global directory of successful people, you may find millions of doctors, engineers, IT professionals, lawyers and advocates who rely upon their formal education. These people may have extreme talent, but what made them success later in life is the higher education they received from schools. These education guided them to study farther into their fields and gave them inspiration. Last, everyone has heard of Bill Gates and his outstanding achievements. You may say that Gates did not receive much academic education, but he still succeed. Well, success isn't a just matter of building a huge firm from scratch and making billions of dollars by that definition, only a tiny number of people in the world could be considered successful. No, success is about making the most of your talents and abilities, and that requires dedication and study in academic institutions that will help you discover your potentials. 本文来源：https://www.wddqw.com/doc/6a2e60e0b8f67c1cfad6b8cb.html
