Some people think that they will get ill if they will use their brains too much. It is not truly. Through many studies，scientists show us that the less you use your brains，the better they will be，but the cleverer you will become. Of course，if you want to keep your mind clear and active，you must take proper rest and study properly. To the teenagers，use their brains in the morning is good for your health.

There are various ways to rest. One of them is a peaceful rest. Sleep is a perfect example. As we all know，lack of sleep can do great damage for our health. Another is an active rest. For example，take a walk outdoors，and do more exercises every day. In everyday life，eating some eggs，meat，fresh vegetables and fruit are also good for the brains.

   One effective way of destroying happiness is to look at something and focus on even the smallest fault. It’s like looking at the tiled（铺瓦的）ceiling and concentrating on the space where one tile is_____ .

The first_____ is gratitude（感激）.All happy people are ______ .Ungrateful people cannot be happy. We tend to think that being unhappy leads people to______ ，but it’s truer to say that complaining leads to people becoming unhappy.

Finally，the belief that something lasting for a long time goes beyond us and that our______ has some larger meaning can help us to feel happier. We______ a spiritual faith， or a philosophy of life. Whatever your philosophy is， it should ______ this truth：If you choose to find the______ in every situation， you will be blessed；and if you choose to find the awful， you will be cursed.

   A hobby is an investment of time. It also can be an investment of money and commitment. Many people choose to develop more than one type of hobby. It can be necessary to select the hobby that is right for you. 【小题1】

Hobbies are usually an activity of some sort that brings out a certain skill that you have. When you have a talent like painting or woodworking，it can be easy to determine which hobby suits your skill. 【小题2】 Skills can be developed and challenged as you go along. It is not a necessary requirement. A hobby is fitting because you love it，not because you're a professional at it.

Some people particularly enjoy taking part in hobbies that they can do in a group with others. It can be a lot more fun to become a member of a hobby group than to sit alone in your basement. 【小题3】 It's important to share interests and networks with other hobby enthusiasts that do what you do.

Hobbies are generally an activity that you undertake（着手做）because of the joy it brings you. Of course many people have discovered the joy that also comes with a hobby that earns you a living. 【小题4】 Just make sure you make the choice that fits your lifestyle and personal preference.

【小题5】 But most of the skilled hobbies like art，building or writing have a series of lessons or tutorials that you can take to further your skills. In some cases it's really a good idea to take lessons，especially if you are clueless as to where or how to begin. Step by step books for most hobbies can often be found in bookstores as well.

   Everyone struggles writing. 【小题1】 Writing is hard. All writers struggle at some point. And even if writing has come easily for you, at some point in your work as a student ,eventually you're going to hit a roadblock（路障）. 【小题2】 When the writing was going well, what was happening? When the writing wasn't going well, what was happening?

 【小题3】 Most people's negative writing experiences happened because of some specific requirements like an exact length. They focus on and worry about what the final product has to look like, like how many pages for a research essay, or if it is in the second or third language, or grammar, like whether it gets communicated in the right language.

Another problem can arise when the need to do well on a paper is extremely important, like a timed essay exam, or a college application essay, or a research paper at the end of the term, and it's tied to the entire grade for the class. So worrying about what will happen if they don't do well- get bad grades, or don’t get into college - creates anxiety.  【小题4】

Try to move to more positive projects. Usually when writing comes easily, the writers feel they have something important to say. 【小题5】 What personal understanding of the subject can you bring to your paper? Why is this subject important? For whom is it meaningful? Who will be reading it? What is it that you really want to say to readers? Those thoughts can cause writing's change for all writers.
