Tips：Look for topic sentence & standout sentence. Paragraph 2 To change bad habits is never easy, even with many attempts. There is a famous saying based on the philosophy of Aristotle: “We are what we repeatedly do.” In many ways, our lifestyle is the sum of choices we have made. We make a choice to do something, and then we repeat it over and over again. Soon that choice becomes automatic and forms a habit that is much harder to change. The good news is that we can change, if we understand how habits work. F What a habit is Tips：Look for topic sentence Topic sentence Leading to the next paragraph Paragraph 3-4 According to modern psychology, we must first learn about the “habit cycle”, which works like this: Firstly, there is “cue”, an action, event, or situation that acts as a signal to do something. Secondly, there is a “routine”, the regular action you take in response to the cue. Thirdly, there is a “reward”, the good thing or feeling we get from the routine. For example, when we feel unhappy (cue), we eat lots of unhealthy snacks (routine), which makes us feel happy (reward) The reward makes us much more likely to continue the cycle, and the bad habit of relying on unhealthy snacks is formed. Topic sentence B The cycle of how habits are formed Tips：Look for topic sentence To facilitate a positive change in our bad habits, we must first examine our bad habit cycles and then try to adapt them. We can do this by combining the information from our habit cycles with our own positive ideas. For example, we could try to replace a negative routine with something more positive. So, when we feel unhappy again (cue), rather than eat snacks, we could listen to some of our favourite music instead (routine), which will make us feel relaxed (reward). Aside from changing bad habits, we can also use the habit cycle to create good habits. For example, when we come to an escalator(cue), our normal routine is to ride it, but we could change this routine into something more positive by taking the stairs instead. Topic sentence Standout sentence Paragraph 5 A How to change a bad habit and create good ones Tips：Look for topic sentence & standout sentence. Many of us try to change bad habits quickly and if we are not successful straight away, we often become pessimistic and give up. In fact, the most successful way to change is not suddenly, but over a period of time. As the Chinese philosopher Lao Zi wrote, “A journey of a thousand miles begins with a single step. "One step seems small, but it is essential. To reach the goal of change, a person must show some discipline and repeatedly take many small steps. After all, it is not easy to break bad habits . Paragraph 6 Standout sentence D Changing habits gradually. Tips：Look for standout sentence. Paragraph 7 For young people, there is plenty of time to change bad habits. However, there is no"magic pill" or delete button that will help you; you have to think about your bad habits and decide on some changes. You have the power to build a happy and healthy life full of good habits! C Young people have the power to build a healthy life full of good habits.

There is a famous saying based on the philosophy of Aristotle: “We are what we repeatedly do.” By citing a quotation What does the quotation"We are what we repeatedly do " mean？我们重复的行为造就了我们.

Secondly, there is a “routine”, the regular action you take in response to the cue. Thirdly, there is a “reward”, the good thing or feeling we get from the routine. For example, when we feel unhappy (cue), we eat lots of unhealthy snacks (routine), which makes us feel happy (reward) The reward makes us much more likely to continue the cycle, and the bad habit of relying on unhealthy snacks is formed.
