5 . Most Chinese know the story of mythological Chang’e. It’s a story about a woman who takes an immortality pill and flies to the moon. The story is s0 popular that people can’t hear the word Chang’e without thinking of romantic images of a moon goddess.

For this reason, China’s mission to the moon was calling for a strong female figure. Therefore, pictures of a 24-year-old female space commander have gone viral on Chinese social media for her work on the Chang’e-5 Moon exploration programme with comments about how she is a “frontline soklier in the field of aerospace” that young Chinese can look up to.

Ms Zhou, 24-year-old lady of the Tujia ethnic group, is China’s youngest ever space commander. She was involved in the successful launch of the Chang’e-5 lunar probe on 24 November, in charge of the rocket connector system, described as a key role.

In Wenchang space launch site, though she is only 1.58 meters tall and looks “mini”, she is called “Big Sister” for her powerful core and energy. Since senior high, she has dreamed! of being a member of a space research team. With her great efforts, she was admitted to an aircraft system and engineering major of a domestic university in 2014, making her acrospace dream come true. To grow into a commander, in two and a half years, she changed five positions to be familiar with multiple posts and types of work, each of which takes great courage and is full of challenges. In a working space with no air conditioning and narrow space to accommodate only three people, she worked for 60 days until the completion of “the Long March 5 rocket goes around” battle.

Her story has received attention from Chinese state-run media as well as overseas media outlets. However, it has not appeared to have had much of an effect on her. According to the media, she declined repeated requests for interviews because she does not wish to let fame get in the way of her work.

6 . In cities with rent control, the city government sets the maximum rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartments. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent-controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city.

Some theorists argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low-paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. The price, which is the wage that employers must pay, increases. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics claim, an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.

Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.

Economic theory predicts the results of economic decisions such as decisions about farm production, rent control, and the minimum wage. The predictions may be correct only if “other things are equal” Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.

10 . When a dog looks at you with big puppy-dog eyes, it’s hard for you to go away, and you may speak out “Awww” without hesitation. However, there’s a reason why you find a dog’s stare so attractive. That sweet stare actually causes the release of a particular hormone, or chemical messenger in the body. This hormone creates feelings of affection in humans. The same thing happens to dogs when people look back at them. Scientists believe this helps people and their four-legged friends bond, or feel connected. Scientists have wondered what causes dogs to lovingly stare at their owners. To find out, a team of researchers from Azabu University in Japan studied 30 owners and their dogs.

The researchers found that after the pets and their owners spent half an hour together, both showed a rise in oxytocin (催产素). One key role of this hormone in many animals is to promote bonding, like that between a mother and newborn. The increase of oxytocin didn’t happen, though, when scientists repeated the experiment with wolves and the humans who had raised them.

A second experiment also found that if dogs were given oxytocin, they looked at their owners longer. Scientists aren’t sure exactly why, but this reaction occurred only with female dogs. Their owners’ oxytocin levels also rose as a result.

The result of these experiments might help answer an age-old question: How did the fearsome wolf ancestor of modern dogs turn into man’s best friend? Takefumi Kikusui, an animal scientist who worked on the study, thinks that the change happened when dogs first became domestic (驯养的).

According to Kikusui, there may have been a small group of wild dogs that were naturally friendlier. “Humans are very sensitive to eye contact. By using this special communication tool, the dogs are able to win over our hearts. If they are more likely to make eye contact, it would be easier for them to bond with dog owners,” Kikusui said.
