塑料源於有機產品,這些產品是由天然製品如纖維素、煤炭、天然氣、鹽,以及原油製成的。原油是由數千種化合物混合而成,必須經過處理才可使用,但這對環境帶來害處。
.
Plastics are derived from organic products which are made from natural products such as cellulose, coal, natural gas, salt and crude oil. Crude oil is a complex mixture of thousands of compounds. It must be processed before being useful. However, it is bad for the environment. .

The story of wearing the wedding ring on the left hand can be traced back to ancient times. In that era, the Romans believed that the vein in the ring finger (the fourth finger) on the left hand ran directly to one's heart. Because of this belief, people keeps this tradition and wear the ring on the left hand. .

能源可通過使用由螺旋槳組成的大型風力渦輪機產生,渦輪機可以連接到發電機發電,也可以利用機械動力來執行抽水或磨粒等工作。當風通過渦輪機時,葉片會移動旋轉軸,藉此產生能量而作使用。
.
Energy can be generated by using a large wind turbine usually consisting of propellers. The turbine can be connected to a generator to generate electricity, or the wind can be used as mechanical power to perform tasks such as pumping water or grinding grain. As the wind passes the turbines it moves the blades, it spins the shaft for generating energy for different tasks. .
