    Beautysleep is a real thing, researches have shown that people who have enough sleeplook more attractive (有魅力的) to others.

    A few badnights are enough to make a person look especially "more ugly", theirsleep experiments show.

    Theresearchers asked 25 university students to join in their sleep experiment.They were asked to get a good night's sleep for two nights.

    A weeklater, they were asked to sleep for only four hour every night for two nightsin a row. The researchers took make—up free (素颜) photos of the volunteers afterboth the good and the bad sleep.

    Next, theyasked 122 strangers to have a look at the photos and judge (评价) them on attractiveness, health,and sleepiness, as well as asking them: "How much would you like to makefriends with this person in the picture?"

    Thestrangers were good at judging whether the person they were looking at wastired, and if he was sleepy, his attractiveness score would be low.

    Thestrangers also said they wouldn't want tosocialize with the tiredstudents. The researchers say this is natural for people. An unhealthy-lookingface makes people run away. In other words, people don't want to hang aroundwith people who might be ill.

    Dr Brewer,an expert at the University of Liverpool said: "Judgment of attractivenessis often unconscious (无意识的), but we all do it, and we are able to judge on even somethingsmall like whether someone looks tired or unhealthy. This study is a goodreminder of how important sleep is to us."

Where do our happy feelings come from? It's dopamine (多巴胺) that works as a star in our brains. It is often called the "feel﹣good" chemical (化学物质). When there's an ongoing dance party in our minds, dopamine is the DJ playing music of happiness. 

Dopamine is important not only because it controls our feelings, but also it plays a big role in different parts of our brains and bodies. As for brains, it influences our motivation (动机) and affects our learning and memory to help us keep knowledge for a longer time. As for bodies, it controls our body movement and helps us do actions more quickly, correctly and smoothly. Thanks to dopamine, we are encouraged to explore and learn more fun things, make more plans and want to achieve more goals. 

What can we do to make dopamine come out? It's interesting that everyday activities like exercise and even listening to music can help our brain to make it. Also, when we experience something enjoyable, like eating tasty food or reaching a goal, our brain releases dopamine. Besides, scientists have also found that dopamine isn't just about personal pleasure, but also does something with social interactions. When we talk with others, share a laugh or a bond with friends, our brains will also release dopamine. Dopamine keeps us feeling that it is enjoyable to be with others. 

However, too much or too little dopamine can be knotty, which means the brain's dance is not easy. If there's too much, it might make us feel too excited. If there's too little, it can make us feel a bit sad. Therefore, we should try our best to keep a balanced diet and do regular exercise, which is really important for a healthy and happy brain. 

So, if we find ourselves in a happy moment the next time, we should know that it's not just our heart dancing with joy, but also a wonderful dance of dopamine creating a beautiful ballet of happiness in our brain. Enjoy the dance, taste the joy, and let the chemistry of happiness lift the spirits to right heights!

 阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。

A new AI system can be used to make predictions(预测) on the crop yields(产量) up to six months before harvest. The tool counts flowers on fruit trees, which can help farmers improve crop yields and make better use of water and labor, and to plan harvests.

The system, developed by researchers at the National Robotarium in Edinburgh, can count flowers on fruit trees from photos taken by a smartphone. It works by knowing features, such as the edges and shapes of flowers. In Spain, studies on peach trees showed the system to be 90% correct in flower counts, which is much better than the 30% to 50% mistakes made by humans, according to researchers.

 "In countries all across the world, farmers often depend on traditional methods to predict their yields, which can lead to big mistakes, " said Fernando Auat Cheein, a professor at the National Robotarium. "The flower-counting AI makes it possible to help farmers make wise decisions about crop management. "

"By paying more attention to the areas of the farm that are expected to produce the most fruit, farmers can make the most of resources(资源), reduce their environmental effect, and improve the harvest, " said Mr Cheein. "Our AI tool can be used with traditional farming practices, making it easier for growers to get help without completely changing their present methods. " The researchers will next compare the AI's predictions with the actual peach harvest in the following months. If these turn out to be effective (有效的), they believe the method could be used for crops such as apples, pears, and cherries, helping fruit growers in Britain, Europe, and other areas.
