The film YOLO (You Only Live Once) directed by Jia Ling, China’s most successful female filmmaker has become a hit recently. In the film, Jia plays Le Ying, a jobless woman in her thirties who still lives with her parents until one day, she meets a boxing coach (拳击教练), Hao Kun (played by Lei Jiayin), and later finds strength and hope in boxing training and changes her life. The actress-director lost 50 kilos which became a hot topic in social media.

After watching the film, many people start trying to lose weight. Some people plan to join gyms, but not all of them can stick to exercise. So how do you make sure you find a gym you like, and more importantly, one where you feel comfortable?

To answer the questions, Jarrod Saracco, a fitness (健身) coach with 20 years of experience in the field, gives his advice. “From the moment you walk in, it should be about the energy and the experience. Do they greet you? Do people working out look like they’re having a good time?”

However, there are so many gyms in China, so choosing the right one may take you a little time. Here are some tips about how to choose a good gym.

Find a gym close to your home. You can walk to the gym to do some sports. It’s better to drive less than 15 minutes. If you find a good place to park your car, your choice may be right.

Visit at your best workout time. Saturday afternoon may be the right hour to check out a gym. You can go and have a look at it. If it is very crowded, try another gym.

Check for clean machines. Keeping things clean or not means the gym is good or bad. A professional staff member should also be wiping (擦拭) down machines in the day. While you are visiting, watch to see whether there’s a strict rule of wiping down everything after use. If not, try another gym.

Computers may be able to help us in more ways. Recent research has showed a new computer program that can learn human emotions (情感).

Researchers asked a group of people to type (打字) two paragraphs from Lewis Carroll’s novel Alice in Wonderland. The people then chose an emotional state they felt while typing. Moods tested were joy, fear, anger, sadness, disgust, shame and guilt. Then the researchers put the text into the computer to study. Surprisingly, the computer was right 70 percent of the time in telling their emotional states. The most correct emotions it guessed were joy (87 percent) and anger (81 percent). The least accurate emotion the computer guessed was sadness (60 percent).The researchers found that the people were hardly typing when they were in a bad mood, which may explain the inexactness of the second result.

However, the findings could have great importance for artificial intelligence (人工智能), and it may allow computers to get along with us in a friendlier manner. “If we could build any system that is intelligent enough to communicate with humans—that is, it can identify users’ emotions and change its behavior accordingly, then using machines could be more effective and friendly.” the researchers wrote in study. For example, when looking for a movie online, perhaps a computer program could make suggestions for films that would match your mood. And as the researchers said, this kind of computer program could also help humans in a number of ways. First, with online teaching, emotionally intelligent computers could change its teaching style to help students learn better. Second, with online talking, doctors were able to tell the emotion of a patient.

There are many kinds of clouds. They are an important part of the earth’s weather.

A cloud is made of water drops or ice crystals (冰晶) floating in the sky. The sky can be full of water. But most of the time you can’t see the water. The drops of water are too small to see. They have turned into a gas called water vapor. As the water vapor goes higher in the sky, the air gets cooler. The cooler air causes the water droplets (小水滴) to start to stick to things like bits of dust, ice or sea salt.

Clouds get their names in two ways. One way is by where they are found in the sky. Some clouds are high up in the sky. Low clouds are close to the earth’s surface. In fact, low clouds can even touch the ground. These clouds are called fog. Middle clouds are found between low and high clouds. Another way clouds are named is by their shape. Cirrus clouds are high clouds. They look like feathers. Cumulus clouds are middle clouds. These clouds look like giant cotton balls in the sky. Stratus clouds are low clouds. They cover the sky like bed sheets.

At night, clouds reflect heat and keep the ground warmer. During the day, clouds make shade that can keep us cooler. Studying clouds helps scientists better understand the earth’s weather.

Scientists also study clouds on other planets. Mars has clouds that are like the clouds, on Earth. But other planets have clouds that aren’t made of water. For example, Jupiter has clouds made of a gas called ammonia.
