Some years ago, a Chinese zoo organized a special diving competition. They 1) (explained, told, said) the people who wanted to enter the competition to dive into a pool where there were some whales. The water was 7 metres deep and very cold and they had to stay there as long as possible without breathing. 26-year-old Yang Yun was a confident diver, but she 2) (has, had, hadn’t) ever dived in such cold, deep water before. When Yun had 3) (been, was, being) in the pool for a few minutes, she found that she couldn’t move her legs. Later, Yun said that she had left very anxious and afraid at that moment. But then a whale called Mila, which 4) (has lived, lived, had lived) at the zoo for some time and was sociable with humans, swam towards Yun. Mila had 5) (saw, seen, see) that Yun was in trouble, and wanted to help her.
When the people around the pool saw Mila pushing Yun out of the water, they understood that the whale had saved the woman. Yun later told journalists that she had 6) (knew, known, knowing) that there was ‘an incredible force’ pushing her up, but that she 7) (didn’t, hadn’t, hasn’t) realized it was a whale. And she said that she 8) (had, did, was) never going to forget Mila – the whale that saved her life.
