Article: A euphemism (from the Greek words eu--well and pheme--speak) is a word or expression that is used when people want to find a polite or less direct way of talking about difficult or embarrassing topics like death or the bodily functions.Most people,for example,would find it very difficult to say in plain language that they have arranged for their sick old dog to be killed.They would soften the pain by saying:We had Ruby put down or We had Ruby put to sleep.Many people prefer to call someone plain than ugly,or cuddly rather than fat. Euphemisms are an important part of every language,but it seems that English has an evergrowing number of them.The nonnative speaker not only has to make sense of the euphemisms he hears,he also has to learn which euphemisms are appropriate in any particular situation.He might be aware that his American friend needs to use the toilet when she asks where the bathroom (or restroom,or comfort station) is,but he is less likely to guess that his English friend has the same need when he says he has to see a man about a dog.He might have learned,for example,that in the family way is a euphemism for pregnant.If,however,he says to his boss,"Congratulations!I hear your wife is in the family way," he would be using an expression that is too familiar for the circumstances. Schools are full of euphemisms.At Frankfurt International School,for example,the special lessons given to students who are having difficulties in their school subjects are called Study Center (in the middle school) and Academic Workshop (in the high school).Teachers rightly do not want to upset students or parents by being too frank or straightforward,and usually choose a softer word or expression to convey the same message.

Options: (A) make themselves understood (B) avoid embarrassment (C) to sound straightforward (D) attract attention

Article: The earliest historical record of the Diaoyu Islands can date back to China's Ming Dynasty about 650 years ago in a book titled "Voyage With a Tail Wind," published in 1403. The book records the first usage of "Diaoyu Islet" and "Chiwei Islet". The names refer to the current Diaoyu Islands and Chiwei Islet. Hu Zongxian, the Zhejiang governor of the Ming Dynasty, placed the Diaoyu Islands and surrounding islets within China's maritime defense system. It demonstrates that the islands have been within China's _ defense region since the Ming Dynasty. Japan claimed sovereignty during the Sino-Japanese War of 1895, seizing the islands by illegal means. The Cairo Declaration issued after World War II stipulated that all territory taken by Japan illegally, including China's northeast, Taiwan and Penghu islets, must be returned to China. In August 1945, Japan announced its unconditional surrender under the terms of the Potsdam Declaration. The declaration laid out that Japan must return Taiwan, the Diaoyu Islands and surrounding islets to China. But the islands came under US control after 1945. In 1951, Japan and the US signed an illegal treaty in San Francisco without inviting China. The islands were then "entrusted" to Japan according to the treaty. On September 18th, 1951, then Chinese Premier and Foreign Minister Zhou Enlai made a solemn statement on behalf of the Chinese government that the Treaty of Peace with Japan signed in San Francisco was illegal , and would not be recognized without the participation and signing of the People's Republic of China. In June 1971, Japan and the United States signed an agreement to hand over Okinawa to Japan. The Diaoyu Islands were mapped into the handover area. China's Foreign Ministry announced on December 30th 1971 that such a move was "totally illegal" and reiterated that the Diaoyu Islands and surrounding islets were "an integral part of the Chinese territory".
