问题 　　Some people say love makes the world go around. Others say it is not
love; it’s money. Since the truth is that it is energy that makes the world go【S1】________
around. Energy is the currency of the ecological system and life becomes
possible even when food is converted into energy, which in turn is used to【S2】________
seek more food to grow, to reproduce and to survive. In this cycle all life【S3】________
depends. It is fairly well-known that wild animals survive from year to year
by eating as many as they can during times of plenty, the summer and fall, 【S4】________
storing the excess, usually in the form of fat, and then using these reserves
of fat to survive during the hard time in winter when food is scarce. But it is【S5】________
probably less well-【S6】________known that even with their stored fat, wild animals spend
less energy to live in winter than in summer. A good case in point is white-
tailed deer. Like most wildlife, deer reproduce, grow and store fat in the
summer and fall when there is plenty of nutritious food available. A
physically mature female deer in the good condition who has conceived in【S7】________
November and was given birth to two fawns during the end of May and first【S8】________
part of June, must search for food for the necessary energy not only to meet
her body’s needs but also to reproduce milk for her fawns. The best milk【S9】________
production occurs at the same time that new plant growth is available. This
is good timing, because milk production is an energy consuming process—it
requires a lot of food. The cost can be met unless the region has ample food【S10】________
resources. [br] 【S10】
选项
答案 can^→not
解析 固定结构错误。句子中用到的是“not…unless…”这一固定结构，表示“除非……才能……”。该句意思是“除非该地区有充足的食物资源，否则无法满足需求。”
