$\text{- Cấu trúc:  }$

- tobe able to+ V(inf); có khả năng làm gì = can+ V(inf): có thể làm gì

( tobe đang chia ở hiện tại đơn)

- Cấu trúc cụ thể: 

(+) S+ am/is/are+ able to+ V(inf) = S+ can+ V(inf)

(-) S+ am not/isn't /aren't+ able to+ V(inf) = S+ can't ( can not)+ V(inf)

(?) Am/is/are+ S+ able to+ V(inf) = Can+ S+ V(inf)?

$2$.Today, doctors can use robots for operations

$\rightarrow$ Am/is/are + able to + Vinf = can + Vinf : có thể làm gì

$3$.Engineers can design movable body parts

$\rightarrow$ Giống câu 2

$4$.These robots can't understand voice instructions

$\rightarrow$ Am/is/are + (not) + able to + Vinf = can't + Vinf

$5$.This robots can't do chores

$\rightarrow$ Giống câu 4

$6$.Scientists can use robots for exploration

$\rightarrow$ Giống câu 2
