    Every people uses its own special word to show its ideas and feelings. Some of these expressions（表达，说法） are commonly used for many years. Others are popular for just a short time. One such American expression is “Where's the beef?” It is used when something is not as good as it is said to be. In the early 1980s “Where's the beef?” was one of the most popular expressions in the United States. It seemed as if everyone using it at the time.

    Beef, of course, is the meat from a cow, and food is more popular in America than a hamburger made from beef. In the 1960s a businessman named Ray began building small restaurants that sold hamburgers at a low price. Ray called this “McDonald's”. Ray became one of the richest businessmen at last in America.

    Other business people watched his success. Some of them opened their own hamburger restaurants. One company called “Wendy's” said its hamburgers were bigger than those sold by McDonald's or anyone else. The Wendy's Company began to use the expression “Where's the beef?” to make people know that Wendy's hamburgers were the biggest. The Wendy's television advertisement showed three old women eating hamburgers. The bread that covered the meat was very big, but inside there was only a bit of meat. One of the women said she would not eat a hamburger with such a little piece of beef. “Where's the beef?” she shouted in a funny way. The advertisement for Wendy's hamburger restaurants was success. As we said, it seemed everyone began using the expression “Where's the beef?”.

    New Zealand is an island country in the southwestern of Pacific Ocean. The country geographically comprises two main lands—the North Island, or Te Ika-a-Maui, and the South Island, or Te Waipounamu, and numerous smaller islands. New Zealand is situated some 1,500 kilometers east of Australia across the Tasman Sea and roughly 1,000 kilometers south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. The country's varied topography（地形）and its sharp mountain peaks, such as the Southern Alps, owe much to volcanic eruptions. New Zealand's capital city is Wellington, while the city that has the largest population is Auckland.

    Polynesians settled in the islands that were to become New Zealand somewhere between 1250 and 1300 AD, and developed a unique Maori culture. In 1642, Abel Tasman, a Dutch explorer became the first European to sight New Zealand In 1840, representatives of the British Crown（王室） and Maori Chiefs signed the Treaty of Waitangi, making New Zealand a British colony. Today, the majority of New Zealand's population of 4.5 million is of European descent(血统), and the indigenous(土著的) Maori are the largest minority, followed by Asians and Pacific Islanders. Reflecting this, New Zealand's culture is mainly originated from Maori and early British settlers, with recent broadening arising from increased immigration. The official languages are English, Maori and New Zealand Sign Language, with English predominant(主要的).

    New Zealand is a developed country with a market economy that mainly consists of the exports of dairy products, meat and wine, along with tourism. New Zealand is a high-income economy and ranks highly in international comparisons of national performance, such as health, education, economic freedom and quality of life.

    When people see machines that respond like humans, or computers that perform amazing feats of strategy, they sometimes joke about a future in which humanity will need to accept robot overlords. But buried in the joke is a seed of unease. Science fiction writing and popular movies have shown us about artificial intelligence (AI) that exceeds the expectations of its creators and escapes their control, eventually outcompeting and enslaving humans or targeting them for extinction(灭绝).

    Even in the real word, not everyone is ready to welcome AI with open arms. In recent years, as computer scientists have pushed the boundaries of what AI can accomplish, leading figures in technology and science have warmed about the frightening dangers that artificial intelligence may pose to humanity, even suggesting that AI capabilities could destroy the human race.

    But why are people so frightened about the idea of AI?

    Elon Musk is one of the famous voices that have raised red flags about AI, In July 2017. Musk told attendees at a meeting of the National Governors Association, I have exposured to the very cutting-edge Al, and I think people should be really concerned about it. I keep sounding the alarm bell. But until people see robots going down the street killing people, they don't know how to react, because it seems so impossible."

    Earlier, in 2014, Musk had labeled AI "our biggest existential threat," and in August 2017, he declared that humanity faced a greater risk from AI than the terrorists. Physicist Stephen Hawking, who died on March14, also expressed concerns about AI, telling the BBC in 2014 that "the development of full artificial intelligence could spell the end of the human race.
