Today, people travel around the world by air and enjoy the great convenience it brings, but studies show that air travel is bad for the environment. It’s responsible for about three percent of the world’s greenhouse gas emissions (排放物). Then do we have to give up flying to save the planet? Maybe not.
Last month, a British airline (航空公司) operated a flight (航班) called Flight 100. It flew from London to New York with some reporters, engineers and government officers on it. There were no paying passengers. The flight was special because the plane used waste fats and plant sugars as fuel (燃料). As a new kind of green fuel, it was different from the traditional fuel and it cut the flight’s pollution by 70 percent according to the company. Some people said that the flight meant a lot. Many more people wanted to have a try on the flight.
However, there are still problems. For one thing, the green fuel costs five times as much as the traditional fuel. For another, it is difficult to make enough green fuel for all the flights around the world in a short time. To provide enough fuel for a large number of planes, farmers will have to grow more plants. Therefore, more forests will be cut down for farmland.
For now, the British airline and other airlines have no plan to provide similar flights for the public. There is still a long way to go before air travel becomes greener. But one day in the future, such flights may become common and the greenhouse gas emissions may be reduced.

When we talk about the UK, there will be many images in mind: the Ferris wheel, Big Ben, red telephone boxes and black London taxis. The taxi has an important role in London.
But what is so special about a simple taxi? First of all, the shape and style are very different from those taxis in other cities. It looks like a half-car and half-van. It has plenty of room in the back, which means it’s easy for disabled people to use.
Besides the style of the car, taxi drivers have an important part in your travel! The drivers have to pass a taxi driving test, and in London it is very difficult. As there are many tourists in London, drivers must know many roads well.
In the taxi, it is easy for the driver and the passenger to have a talk. Getting a taxi means you will share a public space with the driver. The image of a London taxi driver is one that is nice and talkative. Most times when I get into a taxi, we usually talk about sports or new events.
