Tired after eating?

 After a busy morning, lunch can feel like just something necessary but sometimes it also makes you want to take a break at your desk. 

 This is because when humans eat, our blood sugar level is raised after receiving energy from food, which may cause tiredness after meal. Feeling tired can make it hard to focus on the rest of your studies and activities. Here's why and how to improve the situation. 

 Some people overeat instead of stopping when they feel full. For example, when having buffet, people often eat more than they expect.  Because we usually feel tired after working the whole morning without breakfast. This will make us eat more at lunch. 

 The make up of certain foods can also cause you to feel tired. If you had a meal high in fat, such as a hamburger or a pizza, that could make you feel tired. Meals high in added sugar can have the same effect. 

 If you don't get enough sleep, your body increases production of ghrelin, which sends a " feed me" signal to your brain. Not getting enough rest can also have a bad influence on your decision making skills. 
 

A. It's normal to feel tired after lunch. 

B. So make sure you sleep for eight to ten hours every night. 

C. A common reason for feeling tired after a meal is eating too much. 

D. However, not eating breakfast can also lead to overeating later in the day. 

E. So taking a walk after a big meal is a great way to make you feel less tired.

    How green are you? Do you know how to be green?

    We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.

    Reduce

    Reduce means "use less". Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary—or maybe the old one will be just as good! When we buy things, choose local products if possible, and try not to buy too many things from abroad.

    Reuse

    Reuse means "use again". Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup or a paper bag. It's better to use a china (瓷器) cup and a lunch box because you can use them again.

    Recycle

    Recycle means "change things into something else". Though it takes energy to change something into something else, it's better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.

    So please remember these three words: reduce, reuse and recycle.

Have you ever imagined being able to communicate with your pets at home and have them understand everything you say?It sounds too good to be true,but scientists have started using AIto help communicate with animals. 

Professor Bake told Scientific Magazine that AI allows humans to use technology to watch and understand the sounds and signals animals communicate with so we humans can try to speak back to them. She said trying to communicate in animals' language could be better than teaching them how to use human sign language. AI is already helping us communicate with bats and bees. This could change what we know about these animals and our relationships with them. 

Professor Bake explained how Scientist Tovel had used recordings and AI to understand bats. "Bats have their own language. They often argue over food. They have different names,or 'signature calls'," she said,mother bats lower their voice when speaking to their babies. Their voice can never be heard with human ears. But AI makes this possible because a computer can be trained to listen like a bat. "

Actually,AI has so far achieved a lot in this field. For example,the computer not only listens but also watches bees' body movement to understand what they are communicating. Bake said scientists now know how bees say things such as "be quiet" or "stop". Scientist Landlof even created a robot Honeybee that entered a bee's home and was able to communicate with other bees when it wanted them to stop doing something or fly.
