I recently went to my first ever music festival.We Love Green was held over a weekend in a park in Paris.Like most music festivals, it had wonderful singers and music.However, there was something special about this one.You see, this was a green festival!
From the food to the stalls(摊位), everything was as environmentally friendly as possible.The festival was powered by solar(太阳产生的) energy.There were specially labelled(贴有标签的) bins so that the waste could be recycled properly after the festival.Free fresh water was available to everyone so that guests didn't need to buy drinks in plastic bottles which would create a lot of waste.
I found the experience really interesting.Having never been to a music festival before, I was unsure of what to expect.However, I was happy to find myself sitting in a chair eating a healthy, home made fruit cake while drinking tasty juice.There were many stalls for everyone, from small children to the elderly!
This seems like such a great idea, to make everything very fun and not cause great pollution to the environment.I have since discovered that there are more events similar to this across the world! I think it shows people's growing awareness of environmental protection.
I really hope that there will be more events like We Love Green.These environmentally friendly practices tell people being green does not mean being boring.It can be quite fun.As a result, more people may be encouraged to consider the influence they have on the environment.

People have been using the wind's energy for a long, long time.More than 5，000 years ago, ancient Egyptians made boats powered by the wind.In 200 BC, people used windmills(风车) in China.
Today, we collect the wind's energy with wind turbines(涡轮).A turbine is similar to a windmill; it is a very tall tower with two or three blades(叶片) at the top.These blades are turned by the wind.The blades turn a generator(发电机) located inside the tower, which creates power.
Groups of wind turbines are known as wind farms.Wind farms can be found near farmland, in narrow mountain passes, and even in the ocean, where there are stronger winds.Wind farms create power for nearby homes, schools and other buildings.
In places like the Midwest and along coasts, winds can provide cheap power.Another great advantage of wind power is that it is a clean form of energy.Wind turbines do not burn oil or coal and do not pollute the air.
Wind is not always an ideal source of energy, however.Wind speed changes from time to time, depending on the time of day,
weather and location.Wind turbines can be also dangerous for bats and birds.These animals cannot always tell how fast the blades are moving and crash into them.
Title: __1__ Energy Ancient times People in Egypt made wind powered boats over 5，000 yearsago.
People in China used windmills in 200 BC.
__2__ times It is __3__ with turbines, which are tall towers—like windmills with two or three blades at the top and a generator inside.
