не претендую на истину в последней инстанции, но я бы так сделал:1 asked / saw2 was measuring / was trying3 were shooting / arrived4 were sure / had finished5 was working6 was watching / came7 did happen8 knew / happened9 didn't know / had puzzled10 was dreaming / woke11 got / had gone12 told / stayed13 thanked / had done14 met / fell / were working15 had / were living(1) was planting (2) were (3) were unpacking (4) sighed (5) thought (6) were (7) knew (8) felt (9) missed (10) pulled up (11) got out (12) was (13) had seen (14) wondered (15) was (16) walked (17) said (18) told (19) knew (20) has just made (21) asked (22) said (23) smiled (24) seemed (25) had foundпопробую пояснить почему вот во втором задании я поставил так: он сажал растения в то время как был в саду - поэтому (1) was planting.родители были внутри и распаковывали вещи, пока он был в саду, поэтому (3) were unpacking(13) я поставил had seen потому что он увидел того мальчика уже раньше(20) я поставил has just made потому что Мэтт говорит в настоящем времени(25) had found - потому что к тому времени как ему показалось, он уже нашёл другавсе остальные действия мне кажется происходят последовательно, поэтому их в Past Simple.Надеюсь чем-то помог.
