You never forget your first whale. The impact it makes     1     you is huge and life is never quite the same again.

The world seems to be having more and more whale lovers. Since its beginnings in the mid-50s, whale-watching     2     (grow) quickly and now more than 13 million people join     3     (organize) whale watching trips every year.

The trouble is that a few hours of whale watching simply isn’t enough. You go out in the morning and,     4     lunchtime, you are planning your next trip; by teatime, you are planning the one after that. All your holidays center around whales: the only books you read are those about whales, you wear whale T-shirts, and     5     you meet your friends you talk about whales.

So, what is it about these larger-than-life animals     6     makes them so special? Their size is one possible explanation. Imagine     7     (sit) in a small boat next to a blue whale almost as long as a Boeing 737; only a lump of rock could remain     8     (unmove) by an experience like that.

They are great fun to watch, too. Humpback whales, for example,     9     leap into the air and land back in the water with a huge splash. Then there is the striking and deeply moving level of trust     10     many whales show towards people. It’s a truly humbling experience when an enormous whale comes alongside the boat and greets you like an old friend.
