For Nigel Portman, a love of travelling began
with what's called a "gap year". In common with many other
British teenagers,
he chose {#blank#}1{#/blank#} (take) a year out before settling
down to study for his degree. After
doing various {#blank#}2{#/blank#} (job)
to raise some money,
he left home to gain some experience of life in different cultures, visiting America and Asia. The more adventurous a young
person,
the {#blank#}3{#/blank#} (great)
challenge they are likely to set {#blank#}4{#/blank#} (them) for the gap year, and for some, like Nigel, it can result in a thirst
for adventure.
Now that his
university course {#blank#}5{#/blank#} (come)
to an end,
Nigel is just about to leave on a three—year trip that will take him
right around the world.
What's more,
he plans to make the whole journey {#blank#}6{#/blank#} (use) only means of transport
which are powered by natural energy. In other words, he'll be relying {#blank#}7{#/blank#} (main)
on bicycles and his own legs;
and when there's an ocean to cross, he won't be taking a shortcut (捷径) {#blank#}8{#/blank#} flying aboard—he'll be joining the crew of
a sailing ship,
instead.
As well as doing some
mountain climbing along {#blank#}9{#/blank#} way, Nigel hopes to pass on to the people he meets
the environmental message {#blank#}10{#/blank#} lies behind the whole idea.
