Prehistoric men and women enjoyed a more varied diet than people do now, since they ate species of plant and several hundreds thousands types of living things. But only a tiny percentage of these were ever domesticated. Modern shops have hastened a trend towards specialization which began in the earliest days of agriculture. The food of the rich countries has become cheaper relative to wages. It is speedily distributed in supermarkets. But the choice annually becomes less and less great. Even individual foods themselves become more standardized. We live in the world of carrot specially blunted in order to avoid making a hole in the bag, and the tomato grown to meet a demand for a standard weight of weighting tomatoes to a kilo. Siri von Reis asks: "Only the three major cereals (谷物类食物) and perhaps ten other widely cultivated species stand between famine and survival for the world's human population and a handful of drug plants has served Western civilization for several thousand years. A rather obvious question arises: Are we missing something?" After all, there are 800 000 species of plant on earth.

8.National Parks of Canada The wilderness is one of Canada’s great treasures, and the Canadian National Parks are the system through which the Canadian government protects, preserves, and displays some of the country’s most impressive territory for the benefit of residents, visitors, and the environment. In the late 19th century, as Canada’s population continued to grow and more and more of the country’s land was used for cities, factories, mines and railroads, a land preservation movement emerged arguing the government had an obligation to protect some parts of the country from human development and destruction. Beginning in 1885, these legally-protected areas of land became known as Canada’s national parks. Today, Canada has 46 national parks which are managed by the Canadian federal government (specifically, a government agency called Parks Canada) and governed by the terms of the Canada National Parks Act. A national park is not a “park” in the sense ordinary people use the term. Though many are interesting and fun places to visit, complete with camping grounds, hiking trails, picnic tables, beaches, and playgrounds, they also tend to be extremely large areas of land located in generally remote parts of the country, far from cities and towns. The primary purpose of a national park is to preserve land that is important, remarkable, or threatened in some way — not necessarily to make it fun or easy for humans to use. Some of Canada’s national parks, particularly those in the far north are not really intended to be visited by humans at all. Note that every province has numerous provincial parks as well. The province of Quebec, confusingly, calls its provincial parks “national parks,” too. Every national park in Canada is a little bit different, but the majority are heavily forested areas with mountainous landscapes that get very snowy in the winter. Almost all have ample rivers and lakes, and about half border one of the oceans or Great Lakes. Almost all national parks can be used for hiking, cycling, kayaking, and camping, as well as skiing (though usually backcountry skiing, which does not use designated slopes or lifts) and snowshoeing during snowy months. All of Canada’s national parks are run by the Canadian federal government and many have unique rules that must be obeyed. In theory, any park can be visited, but some require visitors to get government permission beforehand, which can vary in intensity based on the park. Many national parks do not permit camping outside of non-designated campsite areas, or require campers to request permission to camp. While the majority of national parks have government facilities within them, such as visitor orientation centres, or ranger stations to provide emergency help or assistance to visitors, many do not, meaning visitors may be taking a serious personal risk when exploring. Canada is famous for its wild animals, particularly bears, which tend to be plentiful in national parks. National park entrance fees have been suspended for the year 2017, as part of Canada’s sesquicentennial but will resume in January of 2018. 16.Which of the following statements is true according to the passage?
A、National parks in Canada are mainly located in downtown area.
B、People are free to visit any national park at any time.
C、Tourists should be prepared for possible risks when visiting some parks without emergency help or assistance.
D、National park entrance fees have been suspended for good.
