The scientists, led by the British Antarctic Survey (BAS), are trying to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf. Professor David Vaughan, science director at the BAs, said, We need to be bold (大膽的) on this one. Larsen C is a long way south and there39。 There is growing concern about the possible impact of climate change in the Antarctic. Earlier this month, a report revealed that melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of the sea level rise.

Thanks to a webcam and microphone, the avatar not only responds to questions the kids may have, but also picks up nonverbal cues. For instance, if a student smiles at Will, he responds by smiling back. This twoway interaction not only helps attract the students39。 The program, in place since August 2018, has been a great success thus far. Ravishankar says, What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention. However, regardless of how popular it bees, Will is unlikely to replace human educators any time soon.（1）What was special for some elementary school students in Auckland?
