  It happened in a New York classroom. Sixteen-year-old
 Taylor Engler came face to face with a cow. But it was
 all in her head.
  She was trying out a virtual reality(VR,虚拟现实)
 headset(头戴式眼罩). It took Berkeley carroll School
 junior students to a farm. The farm was 400 kilometers
 away.
  Students across the US are taking VR "trips". They
 are swimming in the deep sea. They are watching
 medical operations(医疗手术). They are even "walking"
 through the human body. Teachers say this helps
 students understand their learning material(材料)
 and improve their grades.
  "It grabs(吸引) the students right away," Colin
 Jones, a science teacher from Plainview-Old Bethpage
 Central School District, told AP News. He uses a VR
 system called zSpace to cut up cells(细胞). "It's
 something that can be done in 40 minutes," he said.
 "But it could take even a week when you're doing
 a lab(实验室操作)."
  "It's different than watching video because you
 can have more than one perspective(视角). You can
 actually move," Taylor said during her "trip" on
 the farm.
  According to neuroscientist(神经学家) Richard
 Lamb, VR can give people experiences that are
 similar to the real world. Our bodies even react(反应)
 the same to VR as they do to real-life situations.
"Heart rate(心率), brain activity, breathing,
 everything," he said.
  But there are not many classrooms that can use
 this technology. VR systems are very expensive.
 Experts hope that more students can use it in
 the future, especially for doing science 
experiments(实验) that could be too dangerous 
to do in real life.
