American school life is different from (和……不同) Chinese. American students usually get to school at around 8:30 in the morning. They put their school bags in their lockers (柜子) and only take one book, one notebook and one pen to each class. In class, American students can sit in their seats (座位) when (当……时候) they answer their teachers questions
At around 12:00 students have lunch. American students don’t go home for lunch. They have it at school. Most students like pizza(比萨), hot dogs or hamburgers. At 1:00 in the afternoon, they start to have classes. Their classes are usually over(结束) at three o’clock. Then they join in the activities （活动）of clubs or sports.

Scientists say they've developed a new system （系统）.It can use"machine learning" to predict when and where lightning （闪电）will strike （闪击）.The research was led by engineers from Switzerland.
European researchers have estimated （ 估算）between 6，000 and 24，000 people are killed by lightning worldwide each year.The strikes can also cause power cuts，destroy houses and start forest fires.For these reasons，some climate scientists have studied to develop methods to predict and control lightning.But no system has been created to effectively predict lightning.
The new system is being tested in the experiments （实验）.It used a combination of data （数据资料）from weather stations and machine learning methods.The researchers developed a prediction model.It was trained to tell weather conditions that were possible to cause lightning.
The model was created with some data.The data was collected over a 12﹣year period from 12 Swiss weather stations in cities and mountain areas.The data related to（与……有关）four main surface conditions：air pressure，air temperature，relative humidity （相对湿度）and wind speed.
The atmospheric （大气的）data was put into a machine learning algorithm （计算程序），which compared itto records of lightning strikes.Researchers say the algorithm was then able to learn the conditions under which lightning happens.
Amirhossein Mostajabi is a PhD student who led the development of the new system.He said，"Common systems for collecting such data are slow and complex，and they require expensive collection equipment （设备）like radar or satellites （卫星）."
"Our system uses data that can be gotten from any weather station，"Mostajabi said. "This will improve data collection in the areas which are not covered by radar and satellites or in places where communication systems have been cut，" he added.

When Wang Haiyan was young，her favorite toys weren't Barbie dolls.Instead，she started learning to make shadow puppets （皮影）from her father at 13.Now 43，Wang has spent 30 years practicing and spreading the art.
Shadow puppetry is a form of theater that uses puppets made from leather （皮）or paper，accompanied （伴奏）by music and singing.It was invented during the Western Han Dynasty （206 BC﹣AD 24）.It tells us about folk tales and historical stories，passing down culture and customs over thousands of years.
Shadow puppetry is all about creating the puppets and performing with them.Wang 's hometown of Hua county，Shaanxi，is known as the birthplace of the folk art.
Puppet﹣makers must follow 24 steps to make the puppets including washing the leather，carving （雕刻）and painting，according to Wang.Carving is the most difficult part.
"We have a special carving skill﹣ ﹣moving the leather under the knife，" Wang said.It took Wang three years to master this skill.She used a brick （砖块）to strengthen her left hand while practicing.It takes about 3，000 carves to make a shadow puppet， "The complex （复杂的）steps make it hard to hand downthe folk art，" she said.
But Wang has found a way to do so.In recent years，she has made shadow puppets based on some cartoon series and given a livestreaming performance.She used colors like blue and purple that were hardly seen in shadow puppetry and added more sticks to the puppets to make the performance more lively. "I hope more and more young people enjoy shadow puppetry and pass it down，" she said.
