Article: It was originally built to defend an empire ,but now parts of the Great Wall of China are crumbling so badly they need someone to hurry to their defense. About 2,000 kilometers, or 30%,of the ancient fortification built in the Ming Dynasty has disappeared due to natural and human damage, according to the Beijing Times. And the situation could worsen, experts are warning as not enough is being done to preserve what remains. "It's a great pity to witness the Great Wall in such terrible situation ," Mei Jingtian, a volunteer who has worked for three decades to safeguard the structure and has founded the Great Wall Protection Association, tells CNN. About 8,000 kilometers of the structure dates from the Ming period between the 14th and 17th centuries and is considered by some to be the original Great Wall.Of this, 2,000 kilometers is made up of naturally occurring earthworks - and so only 6,000 kilometers of actual Ming dynasty wall was ever built. Stretches built in other eras make up a total length estimated up to 21,000 kilometers. Many visitors to china associate the Great Wall with a widely restored stretch of Ming era wall at Badaling near Beijing, but this is far from typical of most of the structure. According to a 2014 survey done by the Great Wall of China Society, only about 8.2% of the Great Wall is in good condition, with74. 1% classified as poorly preserved, "The Great Wall is a vast heritage site - over 20,000 kilometers - thus increasing the difficulty in preservation and restoration," Dong Yaohui, deputy director of the Great Wall of China Society, tells CNN. "Reliance on a very small amount of manpower by the local heritage departments is not enough to guard and protect the site." A recent increase in interest from tourists in visiting wild sections, known as the "Wild Great Wall," has Accelerated its deterioration ,according to the report.

Article: Singapore is a country with 42% of its population foreign born. Singaporeans, even those of the same ethnic group , have many different first languages and cultures. For example, within the Singaporean Chinese group, nearly a third speak English as their home language while almost half speak Standard Chinese as their home language and the rest speak various Chinese dialects as their home language. Due to these reasons, the English fluency level of people in Singapore varies vastly from person to person. Most reasonably educated Singaporeans do speak Singapore Standard English, alternatively known as Educated Singapore English, which, grammatically, is not different from standard British English, with changes being limited to accent and a few borrowed words, causing few challenges to any native Britons. Singapore English derives its roots from the 146 years of British colonial rule over Singapore until its independence in 1965. Before 1965, the standard form of English in Singapore had always been British English. After Singapore declared independence, English in Singapore began to take a life of its own, leading to the development of modern Singapore English. English had been the official language of the colonial government, and when Singapore gained self-government in 1959, the local government decided to keep English as the main language in order to help develop economy. The use of English as the nation's first language serves to bridge the gap between different ethnic groups in Singapore. English is the global language for commerce, technology and science, and improvement of English also helps to expedite Singapore's development and it becomes important part of the global economy. There is an increasing trend of Singaporeans speaking English at home. For children who started primary school in 2009, 60% of Chinese along with 60% Indian pupils and 35% of Malay pupils mainly speak English at home. Because many Singaporeans grew up with English as their first language in school, some Singaporean Chinese may not be able to speak Standard Chinese.
