Activity 1：
Read the following essay and complete the outline
The importance of making an outline
An outline is like an architect’s plan for a house. An architect plans a house before it is built to make sure that all the parts will fit. Like an architect, you should plan a paragraph before you write it to make sure that all of your ideas will fit. Learning to outline will improve your writing for three reasons.
First of all, it will help you organize your ideas. Specifically, an outline will ensure that you won’t include any irrelevant (不相关的)ideas, that you won’t leave out any important points, and that supporting sentences will be in logical order. Second, learning to outline will help you write more quickly. It may take some practice at first, but once you become used to outlining your ideas before you start to write, you will be surprised at how fast you will actually be able to write. Preparing an outline is 75 percent of the work. The actual writing becomes easier because you don’t have to worry about what you are going to say; you already have a well-organized plan to follow. Finally, your grammar will improve because you will be able to concentrate on it, not on your thoughts or organization. Improved organization, speed, and grammar make learning to outline well worth the effort.

Everyone, whether rich or poor, young or old, man or woman, has one or two hobbies. Hobbies play an important role in people’s life and are important for several reasons.
First, hobbies are likely to lead to a future job．When people find pleasure in a certain hobby, they may devote more time and energy to the field, and the experience and knowledge gained through a hobby is quite useful in doing a hobby-related job．Besides, hobbies help build up good relationship. When people are engaged in something meaningful and interesting, they tend to be happier, forgetting all the worries and troubles disturbing them. What’s more, hobbies are educational. People can learn a lot from their hobbies. For example, people can learn about different cultures and traditions in various places by collecting stamps. Finally, people should learn how to balance hobbies with their work. After all, hobbies are a healthy pastime after work to relax oneself. One should not spend too much time on his hobbies so as to interfere with his work.
