Many people would like to change various things in their life in order to be more eco-friendly. 【小题1】 They range from changing their jobs to their vehicles and even their homes. In what follows, I am going to talk about the most energy-efficient（节能的）small green homes. Keep on reading, as this article is very useful if you would like to change your home into a more eco-friendly one.

【小题2】 This happens because a green home will contain green devices（设备）which need alternative sources of energy such as solar power and wind power. They do not pollute the atmosphere as much as the regular sources of energy. 【小题3】 The process of installing them is kind of expensive but in the long term, it will save you a lot of money.

【小题4】 It will be made out of recyclable and renewable materials. For example, the furniture will be made out of bamboo instead of materials which take years to grow. This means that there is not a risk of them to be used up as in the case of certain types of wood or other materials.

A green house will be decorated by using non-toxic（无毒的）materials. 【小题5】 They contain harmful chemicals which can be dangerous, but the most energy-efficient small green homes do not have this problem.

How to Speak in Public

Many people have a fear of public speaking. They worry that they will lose their words，bore the audience or somehow make a fool of themselves. It is easy to try to avoid public speaking，but that usually doesn't work out. Everyone has to speak publicly at some point in their life. You may give a speech in a class or a meeting. Maybe you'll have to give a speech for some honor you've received. 【小题1】

Relax. 【小题2】 Your audience don't expect you to be perfect. They want you to succeed just as much as you do. If you're thinking you'll forget everything，remind yourself that you are prepared and knowledgeable. Imagine yourself doing well.

Be yourself. You are not Jack Canfield or Tony Robbins. Share your true personality with your audience，and they'll find you reliable. 【小题3】

Know your topic. Try to speak about the subject you know well. Research the topic to make sure that you are correct. Public speaking is easier when you don't feel like a fraud（骗子）.

【小题4】 Choose your message for the group you are speaking to carefully. If you' re giving a public speech, then rude jokes certainly won't be suitable.

Give value. Base your speech on 2 or 3 main points. 【小题5】 They' ll be satisfied if they leave with something they can use, and that is what public speaking is all about.

   It’s great fun to explore new places, and it may be like an adventure, even when you know you’re not the first to have been there. But to make sure not to get lost or waste time going round in circles, the following tips may be helpful.

• Do the map reading if you’re being driven somewhere. It’ll be easier if you keep the map following the direction you’re traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn or you’ll have to move to the back seat.

• Get a group of friends together and go exploring. You’ll need a good map, a compass, a raincoat, a cell phone to call for help in case you get lost, and a bit of cash for emergencies. Tell someone where you’re going before you set out and let him know what time you expect to be back. The purpose of the activity is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.

• See if your school or a club organizes orienteering (越野识途比赛), in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B (and B to C, etc.) in the fastest time, or simply as a spare-time activity. It enables you to be familiar with the use of maps and compasses and gain some practical skills. In some way, it’s not only good fun, but also a great way to keep fit.

No matter which way you choose, it’s not only good fun, but a great way to keep fit.

I’m sorry to trouble you, but _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

   Maybe you are an ordinary student. 【小题1】 This is not necessarily so. Anyone can become a better student if he or she wants to. Here’s how:

Plan your time carefully. When planning your work, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First arrange your time for eating, sleeping, dressing, etc, then decide a good, regular time for studying. 【小题2】 A weekly schedule may not solve all your problems, but it will force you realize what is happening to your time.

Make good use of your time in class. 【小题3】 Listening carefully in class means less work later. Taking notes will help you remember what the teacher says.

Study regularly. When you get home from school, go over your notes, review the important points that your teacher is going to discuss the next day, read that material. 【小题4】 If you do these things regularly, the material will become more meaningful, and you will remember it longer.

Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a subject. The world won’t end if you don’t pass a test, so don’t be over worried.

【小题5】 You will probably discover many others after you have tried these.
