What are you doing this summer? Summer holidays are the time when you can discover new interests and hobbies. Look at these summer camps. Here are two exciting things you could do instead of spending time in front of your computer screen!

It is well known that the weather is constantly changing. Different weather makes people feel different. In August, it is very hot and wet in the southern part of China. People there have heart trouble and other kinds of health problems in this month. In the northern part of China, it is very hot and dry. People have more heart trouble after the weather changes greatly.

The weather can also influence intelligence. For example, the IQs of a group of students were very high when a very strong wind came, but after the strong wind, their IQs were 10% lower. The wind can help people have higher intelligence. Very hot weather, on the other hand, can make it lower. Students often get worse results on exams in the hot months of the year, especially in July and August.

Weather also has a strong influence on people’s feelings. Winter may be a bad time for thin people. They usually feel cold in these months. They might feel unhappy in cold weather. But fat people may have a hard time in hot summer. At about 18℃ people become stronger.

Low air pressure may make people forgetful. People leave more bags on buses and in shops on low-air-pressure days. There is a “good weather” for intelligence and health. People feel best at a temperature of about 18℃.

Yan Ning, a Chinese structural biologist said that she would leave Princeton University and return to help build a medical academy in Shenzhen, Guangdong province.

Yan used to be one of the youngest professors at Tsinghua University. She has won many awards for her studies on protein (蛋白质) at home and abroad.

Yan is going to help set up the Shenzhen Medical Academy of Research and Translation (SMART). It focus on several fields, including scientific research, student cultivation (培养) and financial (资金的) support. Set to be finished in 2025, it aims to be a world-famous medical research academy by the middle of this century. Its director will be chosen worldwide.

Yan said she wanted to support more excellent scholars and deal with health problems humans are facing. For her, Shenzhen is an energetic place where anything is possible. “Shenzhen is the city of dreams, and I want to realize my next dream here,” Yan said in a speech.

Yan’s return can be seen as a case of China paying great attention to developing the careers (事业) of talented people. The country gives good chances, which have made many overseas (海外) students and talents return.

China has taken action to attract global talent. At the beginning of this year, the Ministry of Science and Technology made a policy to encourage companies to hire (聘请) high-level foreign experts.

One day a man found a cocoon (茧) of a butterfly in the forest. He sat there for several hours and watched the butterfly. Suddenly a small opening appeared, and the butterfly made its great effort to force its body through that little hole. Then it seemed to stop making any progress. It appeared as if it had gotten as far as it could and it could go no further.

So the man decided to help the butterfly. He cut off the remaining bit of the cocoon so that the butterfly could come out easily. But to his surprise, the butterfly got a heavy body and very small wings when it came out of the cocoon.

The man continued to watch the butterfly because he expected that the body would grow smaller at any moment and the wings would become larger and be able to fly. But neither happened! In fact, the butterfly spent the rest of its life crawling (爬) around with a heavy body and small wings. It was never able to fly.

The man was in his kindness, but he did not understand the nature rules. Before the butterfly came out of the cocoon, fluid (流体) from its body must be forced into its wings, and then it would be ready for flying. It must have a hard struggle (拼搏) to get through the small opening to get its freedom from the cocoon.

Sometimes struggles are exactly what we need in our life. If God allowed us to go through our life without any difficulties, it would make us fail. We would not be as strong as we could have been, we could never fly.
