问题     When we speak of a human need, we mean something
which is unnecessary to life, something we can live with.                  【M1】______
Food is a human need. We will starve to death if there                     【M2】______
were no food on earth; but even if we have plenty of food,
but of the wrong kind, our bodies will have problem from
lack of the right food. This is known for malnutrition (营                 【M3】______
养不良).
    In countries where are not developed, man’s food                       【M4】______
needs are the same like in the most advanced societies. We                 【M5】______
all need food and could live a good life on very few types of
food. People in very developed countries eat only the kinds                【M6】______
of food which can be grown near their homes, whereas
people in developed countries eat foods which are often
grown many thousands of miles away form their homes.
People in undeveloped countries are happy with less
different kinds of foods than people in very developed ones
are, so we can say that despite the needs of the two kinds                 【M7】______
of people are the same, their wants are different. People in
very developed countries eat many different types of
meat--they could live by only one, but they would be very                  【M8】______
unhappy because every time what they ate was the same.
Even such special foods like chicken would be less fun to                  【M9】______
eat if you had them every day. But we can’t just live on
meat--we need other kinds of food like bread, rice, and
vegetables which are no more necessary to our bodies.                      【M10】______ [br] 【M8】
选项
答案 by改为on。
解析 本题考查习惯用法。live on为习语，意为：“靠……生活。”本句句意为：他们只能吃其中一种为生。
