Unit 5 A tri p on “ The True North” Li Dai yu and her cousin Li u Qian were on a tri p to Canada to bi si t their cousi ns i n Montreal on the Atl anti c coast. Rather than take the aeropl ane al the way, they deci ded to fl y to Vancouver and then take the trai n west to east acros Canada. The though that they coul d cross the whol e continent was exci ti ng. Thei r fri end, Danny Li n, was waiti ng at the ai rport. H e was goi ng to take them and thei r baggage to catch “The True N orth”, the cross Canada train. O n the way to the stati on, he chated about thei r tri p. “You ’re goi ng to see som e great scenery. Goi ng eastward, you’l l pass m ountai ns and thousands of l akes and forests, as wel as wi de ri vers and large ci ti es. Som e people have the i dea that you can cross Canda i n l ess than fi ce days, but they fet the fact that Canada i s 5500 ki lom eters from coast to coast. H ere i n Vancouver, you’re i n Canada’s warm est part. Peopl e say it i s Canada’s m ost beauti ful ci ty, surrounded by m ountai ns and the Paci fi c O cean.

It i s so wet there that the trees are extrem ely tal l, som e m easuri ng over 90 m etres. ” That afternoon aboard the trai n, the cousins settl ed down i n thei r seats. Earli er that day, when they crossed the Rocky Mountai ns, they m anaged to catch si ght of som e m ountain goats and even a gri zzly bear and an eagl e. Their next stop was Cal gary, whi ch i s fam ous for the Cal gary Stam pede. Cowboys from al over the worl d e to pete i n the Stam pede. Many of them have a gi ft for ri di ng wi l d horses and can win thousands of dol ars i n pri zes. After two days’ travel, the gi rls began to real ize that Canada i s quite em pty. At school, they had l earned that m ost Canadi ans li ve wi thi n a few hundred kil om etres of the USA border, and Canada’s popul ati on i s onl y sli ghtl y over thi rty m il i on, but now they were amazed to se such an em pty country. They went through a wheatgrowi ng provi nce and saw farm s that covered thousands of acres. Afrer di ner, they were back i n an urban area, the busy port ci ty of Thunder Bay at the top of the Great Lakes. Because of the Great Lakes, they l earned, Canada has m ore fresh water than any other country in the worl d. In fact, i t has onethi rd of the worl d’s total fresh water, and much of i t i s i n the Great Lakes. That ni ght as they sl ept, the trai n rushed across the top of Lake Superi or, through the great forests and southward towads Toronto. “The True North” from Toronto to Montreal The next m orning the bushes and m apl e trees outsi de thei r wi ndow were red, gol d and orange, and there was frost on the ground, confi rmi ng that fal l had arri ved i n Canada.

They went up the tal CN Tower and l ooked acros the l ake. In the di stance, they coul d see the Mi sty cl oud that rose from the great N i agara Fal s, whi ch is on the south si de of the l ake. The water fl ows into the N iagara Ri ver and over the fal ls on its way to the sea. They saw the covered stadi um , hom e of several fam ous basketbal team s. As they wal ked north from the harbour area, Li Dai yu sai d, “Li n Fang, one of my m other’s old schoolm ates, li ves here. I shoul d phone her from a telephone booth. ” They m et Li n Fei around dusk i n downtown Chi natown, one of the three i n Toronto.
