20世纪加拿大经济状况

各位大侠帮忙说一说加拿大整个20世纪的经济状况，比如20世纪初期经济还不错（好像），一战后全球经济大萧条，三四十年代经济回升，后面的我就不知道了。请各位大侠帮忙分析，总结一下加拿大20世纪的经济，这可能会说到美国，也请帮忙联系一下加拿大与美国的经济关系。750字左右，字数越多越好（有助于我翻译成英文……），少点也没关系，答得好的，多的一定加分，感激不尽！还有一个是我在百度知道上问了这个问题，结果提交问题时忘了选问题类型了，跑到出国/留学那里去了，请问怎么改问题类型？

THE ECONOMY IMPROVES
1.    By the mid-1920s the economy started to improve.
2.   Wheat was an important export, there was enormousgrowth in the exploitation of natural resources and in manufacturing.
3.   Demand for Canadian pulp and paper increased: newmills were built.
4.   Mining also boomed; lead, zinc, silver, and copperwere produced for export, used in the production of consumer goods like radiosand home appliances.
5.   Expansion of forest and mining industries increaseddemand for hydro-electric power; new hydro-generating stations wereconstructed.


The United States Invests inCanada’s Economy
 
1.   U.S. companies invested in pulp and paper mills andmines across Canada.  Almost 75% of thenewsprint produced in Canada was exported to the U.S., and most of the metalsmined in Canada were used in U.S. –made products such as automobiles andradios.
2.   U.S. investors set up branch plants businesses owned and controlled by companies in theU.S., but which operated in Canada.
3.   By the end of the 1920s, the Canadian auto industryhad been taken over by the “Big Three”U.S. auto companies – General Motors,Ford, and Chrysler.
4.   U.S. companies also owned a high proportion ofCanada’s oil business, nearly half the machinery and chemical industries, andover half the rubber and electrical companies.
5.   The U.S. enriched Canada’s economy by extracting orharvesting raw materials (primaryindustries), but these materials were all transported to the U.S. forprocessing and manufacturing (secondaryindustries). The U.S. economy benefited most.
 
Bootlegging Across the Border
 
1.   One product that Canada exported in largequantities to the U.S.: illegal alcohol.
2.   During WW I, the Woman’s Christian Temperance Unionand similar organizations succeeded in bringing about Prohibition, which banned the manufacture and sale of alcoholicbeverages in Canada.
3.   bootlegger – someone who sold alcohol illegally, or who made “bathtub gin,” homemade alcohol.
4.   By 1920 Prohibition was too unpopular with mostCanadians.
From 1921 on, most provincial governments decidedto regulate sales of alcohol rather than ban the product.
5.   In a series of plebiscites(votes on a public issue), Canadians eventually adopted government-controlledliquor outlets.
6.   In the U.S. Prohibition continued until 1933, soCanadians saw the opportunity to supply the U.S. with illegal liquor.
Rum-running– smuggling alcohol into the U.S.– became common and profitable.
