Past simple
1 I didn’t see her in the shop yesterday
2 They didn’t come to the lacture last Monday
3 Mr Brown didn’t ask me about you
4 She didn’t leave for Paris in 1998
5 We didn’t have a picnic last weekend
Present perfect
1 I have already met Mr Bin and his wife
2 Linda has learnt English before
3 I have been to America
4 They have already finished
5 He has been late again
Удачииии !!!!
