From Edmonton, the train headed southeast across the great Canadian Prairie. At school, Daiyu and Liu Qian     1     (learn) that Canada’s population is only slightly over thirty-seven million. However, they did not anticipate seeing such an open country, and were truly     2     (amaze). They went through two wheat-growing provinces,     3     they saw a bunch of farms that covered a very large area.

After another day on the train,     4     (eventual) they were back in an urban area, the city of Winnipeg. From there, they travelled through the night, and woke up in Ontario —a land of forests and lakes. The train thundered on, through the rolling hills. The     5     ( bush) and maple trees outside their windows were red, gold, and orange, and there was frost on the ground,     6     (confirm) that autumn had arrived in Canada. Night came again, and the train turned south     7     Toronto.     8     they woke up the next morning and     9     (pull)back the curtain, they could see the wide stretch of Lake Huron—one of the four Great Lakes on Ontario’s southern border. It was not until 9: 30 a. m. that they finally reached     10     capital of Ontario, Toronto.
