1．The traveller sees what he sees，the tourist sees what he has come to see.

旅行者观称为所看，游览者观称为只看。

—Gilbert K．Chesterton

2．When you travel，remember that a foreign country is not designed to make you comfortable.It is designed to make its own people comfortable.

你在旅行时要记住一点，国外的生活不是为了让你感到舒适。它的设计是为了让其国民感到舒适。                            —Clifton Fadiman

When you travel at high speeds，the present means nothing：you live mainly in the future because you spend most of your time looking forward to arriving at some other place.But actual arrival，when it is achieved，is meaningless.You want to move on again.By travelling like this，you suspend all experience；the present ceases to be a reality：you might just as well be dead.The traveller on foot，on the other hand，lives constantly in the present.For him travelling and arriving are one and the same thing：he arrives somewhere with every step he makes.He experiences the present moment with his eyes，his ears and the whole of his body.At the end of his journey he feels a delicious physical weariness.He knows that sound，satisfying sleep will be his：the just reward of all true travellers.

Canada is the second largest country in the world after Russia.It is larger than the USA and reaches nearly a quarter of the way round the earth.The distance from east to west is over 5，500 kilometres and the country covers six of the world's 24 time zones.However，its population，about 37.8 million, is only about one­fifth of Russia's.

Nearly 90% of Canadians live within 200 km of the border with the United States，which means that Canada contains vast expanses (宽阔的区域) of wilderness to the north.Canada's native people make up less than two percent of the population.

The weather is different from area to area.In the north，the winters are long and hard，with snow for six months of the year.The temperature can fall to －60℃.The west coast of Canada is the warmest place in winter.The average January temperature is 3℃， and in July it is 18℃.Here it rains a lot every month of the year.Plants grow well all the year round and the parks and gardens are famous for their flowers.

Canada has one third of the world's supply of fresh water.There are five great lakes in the south，and there are many others，especially in the north.Most of the electricity is produced by water.The country has a great deal of coal，oil and natural gas，and these are all exploited(开发) for energy.
