If you haven’t already, you too should switch to the latest eco-friendly, energy-efficient, energy-saving LED (Light Emitting Diode) lighting. As the world becomes more focused on green issues, everyone should do their part in practicing energy efficiency, recycling, cutting down their CO2 emissions and much, much more. One of the most successful campaigns that started in Australia is the now world-famous“Earth Hour”. 2.2 million of Sydney’s residents turned off their lights for an hour in a mass attempt to save energy. The following year, the same idea was adopted by a whole host of different cities.
This is a great example of a campaign to promote eco-friendly options and energy efficiency. But while it clearly raises awareness, it is not a long-term solution to energy saving across the developed world. A long-term solution can be found in the form of switching to LED lighting rather than the traditional halogen lights(卤光灯) found in a typical home.
Put simply, LED lighting is the future of lighting. LED lamps use up only a fraction of the energy pared to that of regular lamps. They also produce a quality flicker-free light, and will last longer than a regular light with 50,000 hours being realistic. Not only are they longer lasting and more energy-efficient with no sacrifice in light quality, but they may quickly become a possible substitute (替代物) for regular lamps that have been previously installed by homes and businesses.
An ordinary 50 watt low-voltage halogen light on for 4 hours a day would cost $ 25 per year to run. With a life span of around 3,000 hours it will typically stop working at the two-year mark. compared with the regular one, an LED light of 50 watts operating for the same period will cost roughly $ 6 per year to run and last 50,000 hours. That means it won’t have to be replaced for 24 years! It really is a no brainer to switch to energy-saving LED lighting. Plus, you will be doing your bit for the environment by being more eco-friendly.
1.“Earth Hour”is held in the world every year in order to .
A.ask people to generate more energy for daily use
B.call on people to use less energy as much as possible
C.remind people to remember the days without lights
D.advise people to have a good rest after working hard

If you have a chance to go to Taiwan, there’s one place you should not miss— the Taipei Palace Museum. The museum has around 650,000 pieces of ancient Chinese treasures. These treasures were originally in the Palace Museum in Beijing. But how did they get to Taiwan?
In 1931, the Japanese invaded the northeast part of China. To protect the national treasures from the Japanese, the government of the Republic of China decided to move some important pieces to Nanjing.
However, they did not stay long in Nanjing. In 1949, the people’s Liberation Army won in the Liberation War. The Guomindang government went from Nanjing to Taiwan. Along with them they took the art pieces. The Taipei Palace Museum was set up in 1965 to hold the national treasures.
Taiwan people are very proud of the Taipei Palace Museum. Some of the collections are world famous. One of the most visited art pieces in the museum is the “Jade Cabbage”.
