Simple past tense:
A crow let the nut fall down onto the grass from a tall tree.The nut
did not break_____(not break) open because the grass was too soft.
They/we/you/I/he/she/it + did not ( didn't) ( in simple past tense)______________________________________
Simple present tense:
A crow lets the nut fall down onto the grass from a tall tree.The nut
doesn't break_____(not break) open because the grass is too soft.
Note: You should take about the PAST with the simple past tense.
1) grass <------uncounatble the grass IS.................
2) The nut<------------- just ONE use " doesn't" in present tense.
In present tense, when you see " he/she/it", you have to use" is" or
use " doesn't/ does" followed by a verb or an adverb.
He is sleeping. She is beautiful( adjective). It is nice( adjective). ( present tense)
He doesn't understand ( verb) it.
She doesn't understand ( verb) it.
It doesn't matter( verb).
He doesn't really ( adverb)understand it.
She doesn't really ( adverb)understand it.
It doesn't really ( adverb) matter.
Note: The adverb" really" can be placed after the subject ( he/she/it)
He really doesn't understand it. <-------------------Correct too!
They/we/you/I don't ( do) verb/adverb
_He/she/it doesn't= ( does not) ( does) verb/adverb
仲有have not係咪只可以用係present perfect tense??
Usually it is.
They/we/I/ you + have +past participle ( present perfect tense)
He/she/it + has +past participle ( present perfect tense)
1) They have eaten( past participle).
2) She has finished ( past participle) her homework.
eat ( present) ate ( past) eaten ( past participle)
finish( present) finished( past) finished( past participle)
