Many events happened in April, 2019 around the world. Some of them can cause us great sadness, but some of them can bring us as many inspirations as possible. Let's share a few of them.
| On April 10, humans around the world got their first look at a real black hole. Scientists say it is a landmark in the history of both man and science. The image shows a black hole with a bright ring around it. The black hole is about 55 million light years from Earth. The first observation(观察)took place in April, 2017. However, it took two years to finally get a clear picture. More than 200 scientists helped to take the picture, including 16 from the Chinese mainland. |
| France experienced great sadness on April 15. A fire broke out in Notre Dame, a centuries-old cathedral(教堂)in the heart of Paris. The fire took away the cathedral's spire(尖顶)and a large part of its roof(屋顶). French President said that the French people will rebuild the cathedral together. Notre Dame which plays a big part in the novel was built between 1163 and 1250. The cathedral is home to many great works of art and is one of the world's most famous tourist attractions. About 13 million people visit it every year. |
| A naval parade(海军阅兵)took place near Qingdao, Shandong on that day to celebrate its 70th birthday. The PLA Navy sent out 32 ships and 39 warplanes for the parade. Chinese President Xi Jinping believes that the Navy has been and will always be a force for peace. As a big country with more than 18, 000 kilometers of coastlines(海岸线), China needs a strong navy. History has taught us hard lessons. From the 1850s to 1949, foreign forces made about 470 invasions(入侵)into China from the sea. |
