Sun water and wind are alternative sources of energy．Wind rotating the windmill and moving the sail ．It’s a clean source and a lot of energy ．Unfortunately， if the wind does not blow ．there is no wind energy．As water moves from one place to another ， it makes energy．However， people have to build dams to use this energy source．The dams cost a lot of money ， so water is expensive too.The sun releases large amounts of energy each day．This energy can be converted into electricity .  Solar energy is not only abundant and infinite but also clean and safe.Desfite some drawbacks ， the potention of onternative energy sources is enormous ．However ， how to make full use of the energy resources is a question for researchers all over the world.

Body language is a type of communication in which physical behaviors, as opposed to words, are used to express or convey information. Such behavior includes facial expressions, body posture, gestures, eye movement, touch and the use of space. The term body language is usually applied in regard to people but may also be applied to animals. The study of body language is also known as kinesics.

Although body language is an important part of communication, most of it happens without conscious awareness.

Body "language" must not be confused with sign language. Sign languages are literally languages: they have (their own) complex grammar systems, and they also are able to exhibit the fundamental properties that are considered to exist in all (true) languages. Body language, on the other hand, does not have a grammar system and must be interpreted broadly, instead of having an absolute meaning corresponding with a certain movement, so it is not a language, and is simply termed as a "language" due to popular culture.

In a society, there are agreed-upon interpretations of particular behavior. Interpretations may vary from country to country, or culture to culture. (On this note, there also is controversy on whether body language is universal.) Body language, a subset of nonverbal communication, complements verbal communication in social interaction. In fact, some researchers conclude that nonverbal communication accounts for the majority of information transmitted during interpersonal interactions.It helps to establish the relationship between two people and regulates interaction, yet it can be ambiguous.

It is Solar-energy plane. It looks a normal plane but it has the solar panel on the wings. The panel will catch the sun shine and create the electricity for the plane. It maybe a great invention helping to create the energy and protect environment.

Dịch: Nó là máy bay năng lượng mặt trời. Nó trông như máy bay thông thường nhưng nó có tấm pin mặt trời trên cánh. Tấm pin sẽ nhận ánh nắng mặt trời và tạo ra nguồn điện cho máy bay. Nó có lẽ là một phát minh lớn giúp tạo ra năng lượng và bảo vệ môi trường.

Bicycle is one of means of transport that I most. It is very convenient and good for health. Riding a bicycle, I can develop a strong heart and muscular limbs. Using a bike for transportation also can help you lose weight and improve your overall health. In city or countryside, when you ride bicycle, you don’t need to worry about parking problems and can save money on fuel. Morever, bicycle is only means of transport which  doesn’t pollute the environment. That are some reasons why I bicycle for transportation.
