Choose the best answer to each question.Americans often say that there are only two things a person can be sure in life: death and taxes. And many people feel that the United States leads the world with the worst taxes.Taxes consist of the money which people pay to support their government. There are generally three levels of government tax in the United States: federal, state, and city; therefore, there are three types of taxes. People who have salaries must pay a certain percentage of their salaries to the federal government. The percentage varies for individuals. It depends on their salaries. The higher their salary is, the higher the tax will be.The second tax is for the state government: California, Florida, or any of the other 48 states. Some states have an income tax similar to that of the federal government. Of course, the percentage for the state tax is lower. Other states have a sales tax which is a percentage charged to any items you buy in the states. For example, a person might want to buy a pair of shoes for 25 dollars. If there is a sales tax of eight percent in that state, then the cost of the shoes is 27 dollars. This figure includes the sales tax. The third tax is for the city. This tax comes in two forms: property tax on a home owned by people and excise tax (消费税) on vehicles in a city. The cities use these revenues for education, police and fire departments, public work, including street repairs, water, public transportation, etc.Since Americans pay such high taxes, they often feel that they are working one day each week just to pay their taxes. They often protest that the government misuses their tax dollars and complain that the government spends too much of their taxes on useless and impractical programs.

Steps to Positive Self Talk Most of us are in constant mental chatter. We talk to ourselves all day long and, unfortunately, this self talk is frequently negative. Often it is tainted(玷污) with guilt about our past or anxiety about our future. This negativity can destroy any seed of hope that we may otherwise have in striving for our dreams. Our actions are inspired by our thoughts. If we can change the way we think, we can begin to change the actions we take. It is human nature to seek personal growth; whether financially, emotionally, physically or spiritually. Practicing positive self talk can help us set in motion actions that will bring us greater rewards.The following are several steps to positive self talk. By following these steps you will begin to rid your inner conversations of negativity and instead have empowering thoughts. Eliminate internal negative chatter The first step is one of awareness. It will be hard to make a change to positive thinking without being acutely intimate with the thoughts that run through your mind. Recently, I was amazed to discover deep negative emotions that I had or fewer than 10 minutes. Without awareness, I would have carried the hurt and anger inside. Awareness helped me to bring them out to the open for me to deal with. Undoubtedly it will not be easy to make a switch if you have a long history or negative self talk. Your talk became negative over the years due to various factors. For instance, if your first grade teacher repeatedly told you that you were "stupid", you might believe it to be truly the case. You would find that your inner chatter would often be filled with talk of "I am so slow" and "it is so hard to learn". If you constantly tell yourself such negative stories, your actions are going to reflect your low self esteem. It will be difficult to get very far if you are always putting yourself down. A common negative talk involves telling you "I can’t". When you say to yourself "I can’t" or "it is too difficult", you are creating a resistance. Having such a mental block will prevent you from achieving a task you could otherwise succeed at. Anytime you catch yourself saying "I can’t... ", turn around and challenge your own claim with, "Why can’t I " Research shows that most geniuses became the people they are also because of the hard work they put in. So if you would like to be successful, you need to start saying "I can" a lot more. Positive affirmations Affirmations are positive statements of a desired outcome or goal. They are usually short, believable and focused. By repeating them over and over again, you build inroads into your subconscious mind, opening up the possibility of a new state of thoughts. An important step when repeating affirmations is that you need to read your affirmations aloud with feeling. The mere reading of the words bears no consequence unless you put some emotions behind them. Of significant fact is that your subconscious mind takes any orders given in complete faith and after repeated self talk. So the daily practice of repeating affirmations is important. Initially you may be skeptical toward the statement of your positive affirmation. However, if you follow this simple set of instructions your skepticism will soon give way to a new set of beliefs and then crystallized into absolute faith. Replace negative influences with positive ones It is important that you identify external negative factors in your life which may be holding your thoughts hostage. For instance, your mental state can become toxic by being around friends who are negative. If you are not vigilant enough, you will start to adopt their thoughts as your own. Hence, be alert to what your negative influences are. If they come from certain friends, limit your exposure to them as much as you can. Refrain from discussing your plans with people who will be ur/supportive of your dreams and goals. Instead surround yourself with thoughts and actions from people who will empower you. Being inspired and motivated, you will accomplish greater self growth. The positive energy that they vibrate will start affecting the self talk that you engage in as well. Present tense messages You may find yourself daunted by the many things you need to do in order to reach your goals. It just seems overwhelming to become the success that you secretly desire for. Your mind gets caught up in an endless stream of worry. What may be helpful is to concentrate on steps you can take in the present. If you find yourself becoming stuck, stop and say, "What can I do right now " Change your internal talk from a future anxiety-ridden one to one that is about the more manageable present. You cannot control what will happen in the future but you can take the necessary steps now that will build a better tomorrow. Taking the necessary steps requires you to focus on your inner talk about the present. Confront fears Fear is often what holds you back from your success. You are scared of taking chances because you fear losing the security that you enjoy now. You try to convince yourself that you are happy in your current state when in fact, you are not. Your self talk may sound positive in your attempt to lie to yourself. But somehow, there is an inner knowing that you are short of changing yourself. Ask yourself what you are afraid of. What can be the worst that can happen Take a step-by-step approach in breaking down your fears and see if there is any way round to looking at things more positively. When you confront your fears, you will often realize that the worst-case scenario(局面，场景) is not as bad as you think. In fact, the benefits of change are worth the risk. Your inner talk begins to change at this point. Focus on enjoyable moments It is much easier to have a positive attitude if you focus on the enjoyable moments in life rather than the difficult ones. While there will inevitably be challenges, you need to remember that life consists of ups and downs and the good times are forged through the bad. So choose to fill your mind with positive images and thoughts. Make it a conscious habit. Simply bring your mind hack every time it goes astray in its thoughts. For a start, if you can be grateful for what you have presently, your self talk will also change to be in alignment with one of joy. A state of gratitude does wonders to your psyche. Conclusion Replacing self talk from a negative to a more positive one is not going to happen overnight. If your mind has ingrained habits of thinking negatively, it will take some work and time. However, if you find yourself often struggling, unable to achieve your goals and talking yourself down, then you should grit your teeth and commit to the process of change. By following the above tips to positive self talk, you will experience an improvement in the quality of your life. The rewards are plentiful with greater happiness, peace and joy. Best of all, you feel empowered. With the change in energy, you are more likely to reach your highest potential and achieve success.According to the author, if we want to change our action, we should ______.
