Techeng Island(特呈岛)lies in the southeast of Zhanjiang. The villagers there used to make a living by fishing. But now, most of them make much money by doing business. They believe that their island is a gift from nature and they give thanks to it every day. In 2003, President Hu Jintao came to visit the island and pointed out that the government of Zhanjiang should take the is land into a "civilized new ecotourism island"(文明生态旅游新海岛). Since then, the island has opened a new page in history.

    Today, the island has become a popular place for tourists. It takes you about 15 minutes to get there by boat from Maxie Pier(码头)near Haibin Park. But it is a just 8­minute boat ride from Zhanjiang Port Pier. In the resort(度假村), you can not only enjoy the fantastic sights but also have a lot of interesting things to do, like walking on the beach, visiting the museum and enjoying the delicious seafood. The best way to relax yourself is to enjoy the hot springs(温泉)there.

    Welcome to Techeng Island! It's a place to visit!

    One day, you open the fridge and find some moldy (发霉的)food. But before you can throw it away, your mother stops you. She doesn't want to waste food. She cuts off the moldy part and eats the rest. Is it safe to do this?

    Mold (霉菌)can grow on almost all kinds of food. Mold is usually green, white, black or grey. Mold makes food soft and changes its color. Moldy food tastes quite bad一一and it's not safe to eat.

    If you find mold in soft food, just throw it away. Soft food, such as bread, tomatoes or hot dogs, usually contains water. This allows mold to easily grow below its surface. Bacteria (细菌)can also grow along with it.

    But it's easy to remove mold from hard food. The mold can't grow very deeply inside this kind of food. According to the BBC, you should cut about 2.5 cm around and below the mold to remove it. It's OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, you should still throw it away.

    Most kinds of mold are bad for us. But some kinds of mold can be used to make food. For example, penicillium (青霉菌)can be used to make many types of cheeses, such as blue cheese. These cheeses are safe to eat--and they're quite delicious as well.

    Chinese companies lead in global 5G patent applications(专利应用) with Huawei taking the crown, according to a report by IPlytics, an authorized patent data company. Three companies from China were included in the top 10 list of 5G Standards﹣Essential Patents(SEPs)family owner. Huawei ranked first. ZET Corp, and China Academy of Telecommunications Technology (CATT)grabbed fifth and ninth places, respectively.

    Chinese companies topped the list for most 5G SEPs applications in communication systems by the end of April 2019, accounting for 34 percent of the world's total. Chinese tech giant Huawei has taken a leading role by owning 15 percent of SEPs, according to the report Who Is Leading the 5G Patent Race？

    5G SEP are patents that any company will have to use when carrying out 5G technology and no one can avoid them.

    Different from 3G and 4G technologies, 5G technology will influence various industries and encourage the appearance of many new products, services and industries.

    The automotive sector will most likely be one of the first industries to depend on 5G, which will connect vehicles to other vehicles, roadsides, traffic lights, buildings and the Internet, according to the report.

    "It is 5G that is going to be a huge jump forward for communication systems because only with 5G's higher bandwidth can a number of applications be more advanced (尖端的) and used by most consumers," said Nicole Peng, senior director of the market research company Canalys.

    As 5G technology has combined various industries and technologies, the number of 5G SEPs rose to more than 60,000 globally by the end of April 2019, the report said.
