While the start f a new schl year is always exciting, this year was even mre s fr sme elementary schl students in Auckland, New Zealand. They became the wrld's first kids t be “taught” by a digital teacher, Will. Will is just an avatar that appears n the student's desktp, tablet, r smartphne screen, nt a humanlike rbt walking arund the classrm.
Auckland energy cmpany Vectr and AI cmpany Sul Machines wrked tgether t develp Will, which has been mdelled after the human brain and nervus system, allwing it t perfrm humanlike behaviur. The digital teacher is currently assigned t teach Vectr's “Be sustainable with energy”， a free prgramme fr Auckland elementary schls.
Just like the humans it replaced, Will is able t instantly react t the students' respnses t the tpic. Thanks t a webcam (网络摄像头) and micrphne, the avatar nt nly respnds t questins the kids may have, but als picks up nnverbal cues (非口头提示). Fr instance, if a student smiles at Will, he respnds by smiling back. This twway interactin nt nly helps capture the students' attentin, but als allws the prgramme's develpers t mnitr their engagement, and make changes if needed.
Vectr's Chief Digital Officer, Nikhil Ravishankar says, “What was fascinating t me was the reactin f the children t Will. The way they lk at the wrld is s creative and different, and Will really captured their attentin. ”
Will, in place since August 2018, has been a great success thus far. Hwever, regardless f hw ppular it becmes, Will is unlikely t replace human educatrs any time sn. Fr ne, the avatar's knwledge base is seriusly restricted. But mre imprtantly, even the smartest digital avatars culd never predict and react t all the unexpected situatins that educatrs have t deal with n a daily basis. Hwever, it culd cme in handy as a “persnal tutr”， prviding kids with nenne help n specific subjects r even tpics.
9．What made the students in Auckland mre excited in the new term?
A．A rbt teacher. B．A digital teacher.
C．New classmates. D．New tablets.
10．What's Nikhil Ravishankar's attitude tward Will?
A．Psitive. B．Negative.
C．Dubtful. D．Neutral.
11．What is Will able t d in class?
A．Think like humans.
B．Satisfy all kids' needs.
C．Grab students' attentin.
D．Mnitr students' participatin.
12．What is mainly discussed abut Will in the last paragraph?

9．答案与解析：called 考查非谓语动词。此处与所修饰的词app之间构成被动关系，所以用过去分词形式called，表示“一个被称作Alarm Clck的应用程序”。
10．答案与解析：an/ne 考查冠/数词。hur是单数名词，且其发音以元音音素开头，所以应填an或数词ne。
