We know the mosquitoes(蚊子) very well because they fly everywhere. They can be found almost all over the world, and there are more than 2,500 kinds of them.

No one likes the mosquito. But the mosquito may decide that she loves you. She? Yes, she. It’s true that male(雄性) mosquito doesn’t bite and only the female(雌性) mosquito bites(咬) because she needs blood to lay(孵) eggs. She is always looking for things or people she wants to bite. If she likes what she finds, she bites. But if she doesn’t like your blood, she will turn to someone else for more delicious blood. Next time a mosquito bites you, just remember you are chosen. You’re different from the others! If the mosquito likes you, she lands on your body without letting you know. She bites you so quickly and quietly that you may not feel anything different. After she bites, you will have an itch(痒) on your body because she puts something from her mouth together with your blood. By the time the itching begins, she has flown away.

And then what happens? Well, after her delicious dinner, the mosquito feels tired. She just wants to find a place to have a good rest. There, on a leaf or a wall, she begins to lay eggs, hundreds of eggs.

Have you seen any scarecrows (稻草人)? In the countryside of our country, some villagers like to set up some scarecrows in the fields in order to prevent birds from harming their crops. They think that this can play a role in driving away birds. In fact, not only farmers love to use scarecrows, but also some airports have installed scarecrows in such a developed technology today, which plays a very good role in driving away birds. Some people will say that birds are not fools, and they will come back to eat after a long time. So do the birds really feel scared? Can scarecrows really play a role in driving away birds? Not very—unless you’re willing to put some extra (额外) effort into them.

While traditional scarecrows who couldn’t move do work against “pest birds” (eg. crows and blackbirds), the effect is almost always temporary (暂时的). Over time, the birds get used to scarecrows who couldn’t move and reuse their destructive (破坏性的) habits.

However, a few tricks can up your scarecrow’s game. Researchers have learned that those with realistic facial features (特征) and brightly colored clothes are better at driving away birds. Also, moving a scarecrow around every few days often helps. According to several studies, flailing (大幅波动) scarecrows get the very best results.

A strange way to get relaxed has become popular to cities across China. That is hugging trees. Young people feel comfortable after tree-hugging.

Hundreds of people online share their tree-hugging experiences. They think they feel less stressed (有压力的) and worried. It is also a way of keeping a close relationship with the natural world. By hugging a tree, some of them feel the tree is hugging them back.

Jenny gave up her job because of too much work stress. According to her, hugging trees helps her a lot. She enjoys herself in hugging trees. “Hugging trees helps me relax and lets me go back to a natural state (状态). I feel so free and feel the world is so big.”

In fact, hugging trees is a kind of psychological therapy (心理治疗). It first came from northern Europe. In northern Finland, there’s even a tree-hugging competition every August. A study shows that hugging can lead people to give off hormone (荷尔蒙). Hormone can give people feelings of love and make people less stressed.

Though tree-hugging is helpful for people’s body and mind, there are many things we should think about before we do that.
