When we speak of a human need, we mean something
which is unnecessary to life, something we can live with.1.
food is a human need. We will starve to death if there 2.
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 3.
养不良）。
In countries where are not developed, man's food 4.
needs are the same like in the most advanced societies. We 5.
all need food and could live a good life on very few types of
food. People in very developed countries eat only the kinds 6.
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 7.
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 8.
unhappy because every time what they ate was the same.
Even such special food as chicken would be less fun to 9.
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. 10.
