Basic to any understanding of Canada in the 20 years after the /Second World War is the country’s impressive population growth. /For every three Canadians in 1945, there were over five in 1996. /In September 1996, Canada’s population passed the 20 million mark. /Most of this growth came from natural increase. /The depression of the 1930’s and the war had held back marriages./ The catching-up process began after 1945. /The baby boom continued through the 1950’s, /increasing the population by nearly fifteen percent from 1951 to 1956. /This rate of increase had been exceeded only once before/ in Canada’s history, in the decade before 1911. /Undoubtedly, the good economic conditions of the 1950’s supported a growth in the population, /but the expansion also derived from a trend toward /earlier marriages and an increase in the average family size. /In 1957 the Canadian birth rate stood at 28 per thousand, one of the highest in the world.
the growing interest of consumers in the safety and more nutritional quality of the typical North American diet is a welcome development. However, much of interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence， such claims make it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and form the basis for folklore. Almost daily the public is besieged for “no-aging” diets, new vitamin, and other wonderful foods. There are numerous unconfirmed reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated
grains are better than treated grains and the like.
3.Most European nations follow the parliamentary system of government. Britain has the most well known parliamentary system. Because Great Britain was once a pure monarchy, the function of the head of state was given to the royal family, while the role of chief executive was established with Parliament. Some parliaments, however, do not have a history of monarchy. Israel is a parliamentary system with a president. The president, however, does not hold the same power as a president in a presidential system, but functions as the head of state. In both presidential and parliamentary systems, the chief executive can be removed from office by the legislature. Parliamentary systems use a vote of no confidence where a majority of Parliament members vote to remove the Prime Minister from office. A new election is then called. In presidential systems, a similar process is used where legislators vote to impeach the President from office.
4. Nineteenth-century writers in the United States were powerfully drawn to the railroad in its golden years. In fact, writers responded to the railroads as soon as they began to be built in the 1830’s. By the 1850’s, the railroad was a major presence in the life of the nation. Most writers saw the railroad both as a benefit to democracy and as an object of suspicion. The railroad could ruin nature. Furthermore, in its manifestation of speed and noise, it might ruin human nature as well. By the 1850’s and 1860’s, there was a great distrust among writers and intellectuals of the rapid industrialization of which the railroad was a leading force. Some philosophical historians lamented the role that the new passion for business was playing in eroding traditional values. A distrust of industry and business continued among writers throughout the rest of the nineteenth century and into the twentieth.
5. In 1847 the United States Post Office Department adopted the idea of a postage stamp, much to the objection of those who did not like to pay beforehand. Besides, the stamp covered only delivery to the post office and did not include carrying it to a private address. It is no wonder that, during the years that followed private letter-carrying and express businesses developed. As a result, the government postal service lost volume to private competition. Finally, in 1863, Congress provided that the government should pay the mail carries for delivering mail to private addresses, and that there should be no extra charge for that delivery. But this delivery service was at first confined to cities. As of 1890, of the 75 million people in the United States, fewer that 20 million had mail delivered free to their doors. The rest of the population still received no mail unless they went to their post office.
