1.1.
A ears
B legs
C hands
D
解析：选B。根据后文“he is able to take some small steps with others’ help”（在别人的帮助下他能够迈出一些小步），可知是给腿部发送小电信号，所以选B“legs”（腿）。A“ears”（耳朵）和C“hands”（手）与迈步无关。
2.2.
A can
B must
C should
D
解析：选A。前文提到一位女士说话有困难，现在借助设备能再次和家人“交谈”了，“can”表示“能够”，符合语境。B“must”（必须）和C“should”（应该）不符合文意。
3.3.
A secretly
B politely
C successfully
D
解析：选C。根据“giving them a new chance at life”（给了他们新的生活机会）可知，科学家们成功地帮助了几位残疾人重新开始活动和说话，“successfully”（成功地）符合语境。A“secretly”（秘密地）和B“politely”（礼貌地）与文意不符。
4.4.
A When
B Unless
C Although
D
解析：选A。“it is put on the brain’s surface”（它被放置在大脑表面）和“it receives signals and sends them out”（它接收信号并发送出去）之间是时间关系，“When”（当……时候）引导时间状语从句，符合语境。B“Unless”（除非）表示条件，C“Although”（虽然）表示让步，均不符合。
5.5.
A To
B With
C About
D
解析：选B。“With this ‘translator’”（有了这个“翻译器”），表示伴随，机器才能理解大脑中的想法并采取行动，“With”有“有，带着”的意思，符合语境。A“To”表示目的或方向等，C“About”表示关于，均不合适。
6.6.
A pick up
B take away
C give out
D
解析：选A。根据后文“fill it with water, lift it carefully to the person’s mouth”（把它装满水，小心地举到人的嘴边）可知，机械臂要先拿起杯子，“pick up”有“拿起，捡起”的意思，符合语境。B“take away”（拿走）和C“give out”（分发，发出）不符合文意。
7.7.
A believe
B control
C protect
D
解析：选B。根据前文描述，Beinao - 1能帮助残疾人通过思想让机械臂做一系列动作，也就是帮助残疾人通过思想“控制”事物，“control”（控制）符合语境。A“believe”（相信）和C“protect”（保护）不符合文意。
8.8.
A beautiful
B peaceful
C powerful
D
解析：选C。中国在该领域打破了世界纪录，说明中国在高科技方面变得更“强大”了，“powerful”（强大的）符合语境。A“beautiful”（美丽的）和B“peaceful”（和平的）与高科技无关。
