Every year on May 20, it's World Bee Day. It's a day to thank bees for all they do. Without bees, we might not have any food! Three quarters of the world's flowering plants depend on bees and other animals to grow. When bees fly from plant to plant, they carry pollen (花粉). The pollen makes new plants grow.

There are about 20, 000 different kinds of bees all over the world. They work all day for their queen, the biggest bee in the hive (蜂巢). She will lay 800, 000 eggs in her lifetime. However, there are many problems bees are facing. They are losing habitats (栖息地). They also get sick easily from chemicals (化学物质) used by farmers and they die because of higher temperatures with climate change. These are all making the number of bees drop.

People are now turning to technology to help save the bees. One example is a project called RoboRoyale. It produces robot bees to help feed and look after the queen bee. This will get the queen bee to lay more eggs and make more bees.

In 1994, China began building the BDS, so it wouldn't have to use navigation systems from other countries. It's a lot safer this way. In 2020, the BDS was completed. This achievement made China the fourth to have its own navigation system after the US, Russia and the European Union.

The BDS does not just show where you are. It's the first to let you send messages where there is no phone signal (信号). It has also played an important role in disaster prevention and response (防灾救灾). It even helps farmers in China by providing information for planting, which makes farming smarter.

The BDS is more than a system. It shows China's ability in science and technology. Now, over 120 countries and areas are using it. Wherever you are, the BDS is there to help you find your way.

Do you like junk food? Do you hate eating vegetables, such as (carrot) and potatoes? Do you often sit in front of the desk without (move) for hours? Do you (easy) get angry or stressed out? Try to say goodbye these bad habits on April 7th, the World Health Day. In 1948, WHO (世界卫生组织) (decide) April 7th to be the World Health Day. It hopes to get (many) people to pay attention to their health.

Each year WHO chooses a (difference) theme (主题). This year, it is about high blood pressure. It may seem far from you, but one in three (adult) even some teenagers have high blood pressure according to WHO. The main causes include stress and too much salt. And too little exercise (be) also one of the main reasons.

So to become healthy person, stop those unhealthy habits from now on! Let's eat better and exercise more! With health, we will have a happy and comfortable life!
