Question

---Why don't we take a little break? ---Don't we just have ____? A.it B.that C.one D.this

为什么选D，答案是D
会不会是答案错了

Answer 1

this指代说话者刚才（正在）进行的事情。Don't we just have this？言下之意是想停下刚才（正在）进行的事情，休息一下。

Answer 2

one代替a little break,break是可数名词单数,意为"间歇、停歇".答案为C

Answer 3

this指代a little break，this指代前文，that指代后文 。it和the一般只能指代一个名词break
