Three months ago he was at the Red Sea and when he **(3) came** back, tanned and happy, he said that he **(4) had never had** such a terrific holiday before. As he was very good at swimming and diving and was interested in biology, he managed to join a scientific expedition that **(5) studied** the sea life of the Red Sea coast at that time. The researchers **(6) allowed** him to help them in their work and gave him a special suit for diving, so he **(7) was able to** stay deep in the sea for quite a long time. George was amazed how beautiful the underwater world was. Millions of brightly coloured fish **(8) moved** busily around him. Crabs, turtles, and sea snakes looked at him curiously and then hurried about their underwater business. Once when George **(9) followed** a little crab, a huge fish appeared from behind a coral rock. Though he **(10) had never seen** sharks alive, he recognised it at once. Fortunately, the shark took no interest in him and disappeared into the depth as if it had much more important things to do.
