1 . Current digital technology gives us music of flawless quality. It also makes it easier to copy, upload and stream music without having to download it.
Researchers found that streaming an album over the Internet will use 27 times more energy than it takes to produce a single CD or vinyl record. In any given second, the music platform is serving about 2.5 million streams at the same time. If average albums contain twelve tracks, that means almost 210, 000albums’ worth of music has been streamed. It will use nearly 8,000 times more energy than what making one CD takes.
The study was published before Record Store Day—an event that encourages listeners to buy physical record.
| A．Since our digital music uses less plastic |
| B．This happens every time we stream music |
| C．As a result, streaming music becomes popular |
| D．Although streaming music is a greener alternative |
| E．Meanwhile, if you buy a CD, it’s there permanently |
| F．It wants to convey effects of streaming on economy |
| G．But the researchers aren’t advising playing music traditionally |
2 . People today are not unfamiliar with term such as "going eco-friendly" and "sustainable lifestyle". However, there exists a group of sceptics（怀疑论者）who believe that going eco-friendly is merely a fad（一时的风尚）. I disagree with this viewpoint, Going eco-friendly is not merely a fad and it does, in fact, change the beliefs and attitudes of people.
The long-term presence of environmental organisations shows the efforts that people have made towards going eco-friendly. Organisations such as World Wildlife Fund advocate people to go eco-friendly. The high involvement of the organisations and the participants is thus a strong indicator that going eco-friendly is not merely a fad but a trend that can last decades.
Another strong indicator is the emergence of sustainable products in many industries, such as organic produce and electric vehicles. The consumer demand, coupled with eco-conscious（环保意识的）businesses, is behind the sharp increase in such products. This shows a shift in the beliefs and attitudes of people towards adopting a sustainable lifestyle. Thus, it seems quite certain that going eco-friendly is not merely a fad.
While some people who broadcast their eco-friendly practices are criticised for just hoping to project an eco-conscious image, there are a number of celebrities who have been practising the zero-waste lifestyle for years. For those who do so for years, and not mere days or months, it is indeed a commitment that can only come with a true change in beliefs and attitudes towards caring for the earth.
The call to save the earth looks set to stay. With the development of technology and the appearance of many platforms advocating going green, people are more willing to change their beliefs and attitudes when they can learn about and appreciate the positive impact of the work of different environmental organisations and individuals. It is hoped that these effects will go a long way in ensuring that our planet will remain a suitable place to live in.

4 . When early colonial settlers went to America, they took many forms of dance to their new home. Square dancing, one of the oldest forms of American folk dancing, developed from several different Old World group dances, mainly English country dances, and the French quadrille (卡德利尔舞).
In the American version, a square is formed by four couples.
The caller—someone who calls out the dance steps in time to the music—was a completely American invention.
Although popular for years, square dancing seemed to be going out of style and fading away until the early 1930s, when Henry Ford helped revive interest in it. Ford, the automobile manufacturer, used to vacation at the Wayside Inn in Massachusetts.

Iowa has been tirelessly providing food, clothing, love» and medical care to hundreds of adopted kids since the 1970s.

6 . Farms of the Future
Skyscrapers(摩天大楼) are the ultimate symbol of urban life. By 2050, almost 80 percent of the earth’s population could live in cities. The human population could increase to 9.1 billion people yet the amount of land available for farming will be the same.
Vertical farms, where farmers could grow crops in environmentally friendly skyscrapers, could be the solution. In spite of concerns over high costs, experts want to make these urban farms a reality and use these skyscrapers to grow crops.
Vertical farms would have many advantages, experts say. The food would be grown with minimal effects on the environment. Unlike traditional farming, vertical farming would not force animals out of their habitats by taking over large areas of land, nor would it pollute the air with the use of heavy farming equipment.
Growing prosperity has led to many people demanding that all foods are available all year round. Indoor farming could produce crops constantly and crops would not suffer from weather-related problems like drought or flooding. In addition, the use of agricultural chemicals for controlling insects would be minimal.
Experts agree that the new farming practices are needed to support the planet’s need for more and more food at affordable costs, both to the farmer and to the consumer. Vertical farms may be a small-scale answer, but the best ideas could be yet to come.
| A．Still, there are some people who are critical of vertical farms. |
| B．That is where vertical farms are often needed for year-round crops. |
| C．So how to meet the increasing food needs of our planet could be a big problem. |
| D．For these reasons, natural light cannot be a workable solution for vertical farms. |
| E．Vertically grown food is grown in environmentally controlled conditions in big cities. |
| F．Those farms would also reduce the cost and negative effects of transporting food over distances. |
| G．They believe that we can increase the food production by changing our thinking from out to up. |
