Surely we should do it as much as possible. But where should you go this year? National Geographic Traveler magazine has listed 16 cool places to see in are three of them as below: The Great Barrier Reef (大堡礁 ), Australia It’ s a mustsee if you go to Australia. Lying in northeast Australia, the Great Barrier Reef is the world’ s largest reef system. There are about 3,000 reefs and 900 islands, extending (延伸 ) over 2,600 kilometers. You can see them all the way from outer space! The reef is home to many animals: fish, birds, turtles, sharks and even whales. Your visit will not be boring. Snorkeling and scuba diving will bring endless fun. Imagine seeing different sea plants and swimming with a big sea turtle! Washington DC, US As the political heart of the United States, the city is surprisingly open to visitors. Every year from March 31 to April 15, there is a Cherry Blossom Festival. People can fully enjoy springtime by boating, cycling or simply walking around the 3,000 cherry trees. You can also go to lots of free museums in the city. The Hirshhorn Museum and Sculpture Garden is great for modern art. The National Museum of the American Indian is all about native cultures. And of course, no Washington tour is plete without seeing the White House, the Capitol and the Supreme Court , the three pillars (核心 ) of the US government. San Sebastian (圣塞瓦斯蒂安 ), Spain This city often tops lists as one of the world’ s best places to eat. It has more Michelinstarred restaurants per square meter than any other place in the world, according to CNN. Pintxos is a famous snack in San Sebastian. It is made of small slices of bread, meat and seafood, all fastened (固定 ) with a toothpick. The culture of San Sebastian is just as good as its food. As the 2021 European Capital of Culture, the city will host many special events. One of them will be an outdoor performance of William Shakespeare’ s(莎士比亞 ) A Midsummer Night’ s Dream (《仲夏夜之夢》 ). This year is the 400th anniversary(周年紀念 ) of the great English playwright’s （劇作家） death. 54. ________ places are mentioned to see in 2021 in National Geographic Traveler magazine?

William Shakespeare was born 400 years ago C Have you heard about the periodic table (元素周期表 ) lately? Well, there’ s some big news about this special table, but first, remember that the periodic table is used for all the elements（元素） , or things that make up our world. Elements are all around us. Iron is one of the most mon elements found on the earth. You probably know the element oxygen (氧 ), which is the element that we breathe in all the time. And elements can bine (結(jié)合 ) to make new things like H2O. This is hydrogen (氫 ) and oxygen put together, also known as water! Learning about these things helps us better understand the world we live in. But have you ever noticed something missing in the periodic table? There were already 114 elements. But the seventh row of the table was not finished, until now! In December, scientists from the IUPAC（國際純粹與應(yīng)用化學(xué)聯(lián)合會 ) found the four elements that were missing. They are elements 113, 115, 117 and 118. “To scientists, this is of greater value than an Olympic gold medal,” Ryoji Noyori, a Nobel honored chemist said. The new elements are heavy metals and were made in lab. These kinds of elements can’ t be found in nature. Scientists are still looking for ways to use these elements, and other elements in the eighth row in our daily lives. Scientists have been working on this for 10 years, but the work is not done. Now they will prepare to look for “ element 119 and beyond” . But for now, be mindful (留心的 ) when you read your science books because the periodic table might be outdated (過時的 ). 58.
