　　Some people say love makes the world go around. Others say it is not love; it's money.Since the __1__truth is that it is energy that makes the world go around. Energy is the currency of the ecological system and life becomes possible even when food is __2__converted into energy, which in turns is used to seek more food to grow, to reproduce and to survive. In this __3__cycle all life depends. It is fairly well known that wild animals survive from year to year by eating as many as __4__they can during times of plenty, the summer and fall,storing the excess, usually in the form of fat, and then using these reserves of fat to survive during the hard time __5__in winter when food is scarce. But it is probably less well 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 __6__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 __7__has conceived in November and was given birth to two fawns __8__during the end of May and first 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 __9__best milk 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 need can be met unless the region has __10__ample food resources.

　　答案及解析:

　　1.Since--however/But

　　该句子与前面两个句子在意义和逻辑上是转折关系，而since只能引导原因状语从句或者时间状语从句。

　　2.even--only

　　用only强调条件when food is converted into energy，表示“只有当食物转化为能量时”，而even没有这个意思。

　　3.In--On

　　此处实际上考查的是depend on，为了强调状语，把on this cycle放在了句首，正常的顺序应该是“All life depends on this cycle”。

　　4.many--much

　　这里much指代的是不可数名词food。

　　5.time--times

　　根据上下文的语境，此处time为“某一时期的生活状况，环境等”的含义，一般用复数形式times，再如：We lived through terrible times during the war years。

　　6.is^--the

　　这句话是说：一个很好的例子是白尾鹿。这里是表示特指，所以white-tailed deer前面应该有定冠词the。

　　7.the--in good condition为一个习语，good前面没有冠词。再如：The goods arrived in good condition。

　　8.was--句子的主语是怀孕的成年母鹿，与give birth to 是施动者与动作的关系，不应用被动语态。

　　9.reproduce--produce

　　根据常识和上下文的内容母鹿所需的能量是为了产奶(produce milk)，而不是繁殖奶(reproduce milk)。

　　10.can^--not

　　句中用到的是“not…unless…”这一固定结构表示“除非…，才能…”。
