16. a 考查冠词。名词farm第一次出现，表示泛指，故填a。
17. Luckily 考查副词。用副词修饰整个句子。
18. for 考查介词。根据句中的exchange可知，用介词for。exchange for交换，兑换。
19. was left 考查动词的时态和语态。文章中的时态都是用的过去时，what与leave是被动关系，故用一般过去时的被动语态。21世纪教育网版权所有
20. when 考查连词。根据“…the cow was eating grass…it began to rain heavily.”可知，本句中一个动作发生，另一个动作正在进行，用连词when。【来源：21•世纪•教育•网】

Are you facing a situation that looks impossible to fix?www.21-cn-jy.com
In 1969，the pollution was terrible along the Cuyahoga River near Cleveland, Ohio. It __61__(be) unimaginable that it could ever be cleaned up. The river was so polluted that it __62__(actual)caught fire and burned. Now, years later, this river is one of __63__ most outstanding examples of environmental cleanup.
But the river wasn't changed in a few days __64__ even a few months. It took years of work __65__(reduce) the industrial pollution and clean the water. Finally, that hard work paid off and now the water in the river is __66__(clean) than ever.
Maybe you are facing an impossible situation. Maybe you have a habit __67__ is driving your family crazy. Possibly you drink too much or don't know how to control your credit card use. When you face such an impossible situation，don't you want a quick fix and something to change immediately?
While there are __68__(amaze) stories of instant transformation, for most of us the __69__(change) are gradual and require a lot of effort and work, like cleaning up a polluted river. Just be __70__(patience).
61. was 上文提到的事情是1969年的事情，所以这里应该用过去式。
62. actually 这里应该用副词来修饰动词caught。actually实际上。
67. that/which 也许你有一个使你的家人发疯的习惯。这里habit是先行词，which或that引导的是定语从句，并且在从句中作主语，不能省略。
68. amazing 空格处应该用形容词来修饰后面的名词。amazing令人吃惊的；amazed感到吃惊的。
69. changes 对于我们大多数人来说，变化是逐渐的，需要很多努力和工作。因为这里缺少的是句子的主语，根据谓语动词are可知主语应该是复数，故用changes。
70. patient patience是名词，因为空格前有系动词be，所以这里应该用形容词patient。

One morning, I was waiting at the bus stop, worried about__61__(be) late for school. There were many people waiting at the bus stop, __62__ some of them looked very anxious and __63__(disappoint).

Then the driver stood up and asked，“__68__ anyone lose a suitcase at the last stop？” A woman on the bus shouted, “Oh, dear! It's __69__(I)．” She pushed her way to the driver and took the suitcase thankfully. Everyone on the bus began talking about what the boy had done, and the crowd of strangers __70__(sudden) became friendly to one another.
61. being 介词about后使用v.ing形式，因此用being。
62. and 根据语境可知上下文之间是顺接关系，故用and连接。
63. disappointed 本句的主语是some of them，所以使用形容词作表语。
64. to next to…在……旁边。
65. caught 根据文章第一句“One morning, I was waiting at the bus stop…”可知本文叙述的是一件过去发生的事情，所以使用一般过去时。【出处：21教育名师】
66. to stop refuse to do sth拒绝做某事。不定式作动词refuse的宾语。
67. riding keep doing sth不停地做某事 。
68. Did 本句是直接引语，是一个一般疑问句。因为询问的是过去发生的事情，所以使用助动词did。
69. me/mine 此处可以使用名词性物主代词mine，相当于my suitcase。
70. suddenly 此处应该使用副词来修饰句子的谓语动词，在句中作状语。
