UNESCO in February, 2019 called it an
2、 absolute masterpiece, not only because of the ambitious character of the undertaking but also because of the perfection of its construction. But perfection isnt protection. 51.2 percent of the Great Wall either has already disappeared or is at significant risk of disappearing. Besides wind and rain
3、 erosion, the main reasons for the destruction of the Great Wall are human factors such as tourism, construction, and human contact. Pamukkale, Turkey Pamukkale, which means “cotton castle” in Turkish, is famous for its shining white calcite terraces(方解石阶地) with warm and mineral-rich water flowing.
4、Before being listed as a World Heritage Site in 1988, Pamukkale had been severely damaged by human activities. People used hot spring water to fill swimming pools;some visitors stood on the rocks and some even bathed in the hot springs with soap and shampoo. To protect the terraces, the Turkish gove
5、rnment has decided to pull down the hotels and require all tourists to visit this site barefoot.

6、 expected to suffer increasingly frequent bleaching events, cases in which corals turn white and may die, according to a UNESCO report. The heatwaves caused by global warming have killed half of the coral here in the past two years, according to a CNN report. Pollution from industry development and
7、harmful fishing practices are also big concerns. The Dead Sea, on the Israel-Jordan border At 429 meters below sea level, the Dead Sea is 8 times saltier than the ocean, meaning that the water is so dense that even tourists who cant swim will be able to float. But the seaside resorts built in the 19
8、80s now sit kilometers away from the edge of the water, which has lost half of its surface area in the past 40 years. The damage is irreversible due to the nature of the mineral industry and the type of the agricultural use that consumes lots of water. 1.Which of the following are you required to vi

12、ed to be a writer. I have a good imagination and would write amazing stories in my mind.

14、white room writing a novel. Then I hear a voice say repeatedly, “Now it is time to try something new!” It wasnt just a dream;it was my opportunity to make something good out of my life.

19、bottles hurt your wallet,it also increases pollution and wastes energy. Only 23% of all plastic in America ends up in a recycling bin, meaning over 1 billion dollars worth of plastic is treated as rubbish a year. Recently, Skipping Rocks Lab has invented a kind of water bottle called Ooho. It is a c
20、onvenient,clear water bottle that can either be drunk or be eaten. To drink it,you can either peel off the membrane(薄膜) or tear a hole in the membrane with your teeth to pour the water into your mouth. To eat it, you simply put the whole bottle in your mouth. One problem the scientists have run into
21、 is how to ship lots of Ooho bubbles without arriving with a very wet truck. However, they have attempted to package units of individual bubbles together inside a larger and thicker membrane. It is targeting large outdoor events such as marathons,music festivals,and sports events,where tons of plast
22、ic bottles are used,and frequently left behind as litter. And too much plastic is sure to do harm to the environment,which could account for the purpose of such a new invention.

29、cao to grow. But rising temperatures over the next three decades caused by climate change are expected to result in a loss of water from the ground, which scientists say could upset this balance.

Farmers in the region are already considering moving cacao production areas thousands of feet uphill into mountainous areasmany of which are currently preserved for wildlife. But a move of this scale could destroy the ecosystems that are already under threat from illegal farmi
31、ng and deforestation. One of the problems, according to Doug Hawkins, is that cacao farming methods have not changed for hundreds of years. “Unlike other tree crops that have benefited from the development of modern, high yielding strains and crop management techniques to realize their genetic poten
32、tial, more than 90% of the global cacao crop is produced by small farms with unimproved planting materials,” he said. “It means that we could be facing a chocolate decrease of 100,000 tons a year in the next few years.” Now scientists at the University of California, Berkeley have teamed up with Ame
33、rican candy company Mars to keep chocolate on the menu. Using the controversial(有争议的) gene-editing technology known as CRISPR they are trying to develop a type of cacao plant capable of surviving in dryer, warmer climates.
