你好,同学,才看到你向我们团队发来的求助题,现在为你解答
正确答案:选D. be able to
即:This kind of robot will ( be able to ) help people do housework.
翻译:这种机器人将能够帮助人们做家务.
解析:be able to 与 can 的区别:
1)can could 表示能力;可能 (过去时用could), 只用于现在式和过去式(could).be able to可以用于各种时态. 如:
They will be able to tell you the news soon.
他很快就能告诉你消息了.
2)只用be able to
a. 位于助动词后.
b. 情态动词后.
c. 表示过去某时刻动作时.
d. 用于句首表示条件.
e. 表示成功地做了某事时,只能用was/were able to, 不能用could.
综上所述,只有D是正确的.
