not後面幾時系跟原式？

Active Voice

do not attend 是正確的
如果是 past tense 則會用 did not attend, "attend" 依舊用原式不變。


Passive Voice
is/am/are/was/were attended
is/am/are/was/were not attended

這裏則用 past participle.

我有條改錯題：
In Colonia times, children often do not attend high school, knowing that they were needed to help with the family business.
本書話do not attend系錯，attend要改成attended
點解啊...？

如果你本書話係由 do not attend 改成 do not attended, 咁應該係你本書錯。

如果係我做呢題, 我會把 do 改成 did, 即改成 past tense, 因為 Colonia times 已經過去, 而且後句的 were 可以看成是提示。

In Colonia times, children often did not attend high school, knowing that they were needed to help with the family business.
