Historically，most cars have run on gasoline（汽油），but that may change in the future：cars can also run on other liquid fuels（液体燃料）and electricity.
Gasoline is from oil.The energy in gasoline comes from hydrocarbons（碳氢化合物）.Gasoline provides great power for cars.However，it causes environmental problems，like air pollution and temperature rise.So gasoline can't be the best fuel.
Another choice is electricity.Electricity cars can be as efficient（效能好的）as cars using gasoline，And they produce less pollution.But electric cars themselves are more expensive.Good news is that the cost has been lower and there are more and more places for the cars to get electricity ever since 2010.
The other choices are other liquid fuels.Many of these can be stored in the same places as gasoline，and used in the same cars.They can also be friendly to the environment.
One way to make such fuels is to get CO 2from the air and put it in water.Through chemical reaction，hydrocarbons can be created.However，these fuels take up more space.
Another way is to make such fuels from plants which take in carbon from the air.These fuels are greener in use.But not all of them can be as efficient as gasoline.
For a fuel to be the best，people have to be able to afford it.Unluckily，almost every green technology is more expensive than that of using gasoline.Governments and car producers are doing everything they car to cut down the costs.In the end，the best fuel will be both affordable for car users and green for our planet.

Many of you have heard a Cinderella（灰姑娘） story，but you may not know that there are over a hundred different ways to tell the Cinderella story．When writers tell the same story in a different way，it is called their"version"of the story．The story of Cinderella has many different versions．Let's read two of them and find out how they are different．
The version that most people know is the oldest one written in 1697 by Charles Perrault from France．This is the version where the birds help make Cinderella's dress and the mice turn into carriage men（马车夫） and help Cinderella go to the dance in a pumpkin（南瓜） carriage．In this version，many of the animals are Cinderella's friends．They help her meet the Prince．Cinderella marries the Prince and they live happily together ever after．

The birds now live in the tree and they give Cinderella a dress of gold and shoes of gold．Cinderella goes to the party to meet and dance with the Prince．Later，he finds Cinderella at home doing work for her stepmother（继母）．Cinderella marries the Prince and they live happily ever after．
