Question

   It’s very important that we all recycle. In nature，everything 36     again. For example，when an animal dies it becomes 37      animal’s food. Nothing is wasted. But humans have created things like plastic bags 38      can’t be broken down by nature. Our rubbish kills animals and 39      water and soil. 40      we continue making too much rubbish the problem will only get worse. If nature can’t reuse the rubbish we must recycle 41      We should clean up the rubbish we’ve made because nature can’t.

Recycling is also the right thing to do for another reason. The earth is rich in natural materials like water and trees 42      these materials are not endless. We use up our natural materials much 43       than the earth is able to reproduce them. For example each year we cut 44      more than 6 000 square miles of forest. But it takes an average of 25 years for a new tree 45     

Recycling can help us save the earth so let’s take action right now.

Answer 1

 36. C主语everything是use动作的承受者，要用被动语态。37. A  此处是不定数目中的另一种动物。故选A.38. B先行词是bags 在从句中作主语，应用关系代词that或which 。故选B.39. A根据空格前的kills可知，此处要用一般现在时。40. D句意为:如果我们继续制造太多的垃圾，问题将会变得更糟糕。此处表示条件，故选D.41. C  rubbish是不可数名词 要用代词it来代替。42. A根据句意可知，前后句是转折关系。故选A.43. C根据连词than可知，要用比较级p44. B  cut down砍倒。45. D此句中的it是形式主语，真正的主语是动词不定式to grow.
