In 1969,the pollution was terrible along the Cuyahoga River near Cleveland,Ohio.It 1.　　　　 (be)unimaginable that it could ever be cleaned up.The river was so polluted that it 2.　　　　(actual) caught fire and burned.Now,years later,this river is one of 3.　　　　 most outstanding examples of environmental cleanup.  But the river wasn’t changed in a few days 4.　　　　even a few months.It took years of work 5.　　　　 (reduce) the industrial pollution and clean the water.Finally,that hard work paid off and now the water in the river is 6.　　　　 (clean) than ever.  Maybe you are facing an impossible situation.Maybe you have a habit 7.　　　　 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 8.　　　　(amaze) stories of instant transformation(改变),for most of us the 9.　　　　(change) are gradual and require a lot of effort and work,like 10.　　　　(clean) up a polluted river.Just be patient.  语篇导读:本文通过清理凯霍加河河道污染的例子说明了这样一个道理:只要我们坚持不懈,就可以做成那些看似不可能的事情。 答案及剖析: 1.was　考查时态。前句有时间状语In 1969,因此此处描述的是过去的情况。应用一般过去时,故填was。 2.actually　考查副词。应用副词修饰动词,故填actually。 3.the　考查冠词。后面有形容词的最高级,因此该空填定冠词the。 4.or　考查连词。本句为否定句,故用or连接两个并列成分。 5.to reduce　考查非谓语动词。本句是“It takes+时间+to do sth.”句型,因此本空填不定式to reduce。 6.cleaner　考查形容词的比较级。空后的than ever暗示空处应填形容词的比较级cleaner。 7.that/which　考查定语从句。本句含有定语从句,先行词为a habit,指物,在从句中作主语,应填关系代词that/which。 8.amazing　考查形容词。本空在名词之前,且修饰物,故应用形容词amazing作定语。 9.changes　考查名词的数。本句为主系表结构,空格后的are gradual暗示本空填名词复数changes。 10.cleaning　考查非谓语动词。like是介词,此处要用v.-ing形式。 Ⅱ.短文改错 假定英语课上老师要求同桌之间交换修改作文,请你修改你同桌写的以下作文。文中共有10处语言错误,每句中最多有两处。每处错误仅涉及一个单词的增加、删除或修改。 增加:在缺词处加一个漏字符号(∧),并在其下面写出该加的词。 删除:把多余的词用斜线()划掉。 修改:在错的词下划一横线,并在该词下面写出修改后的词。 注意:1.每处错误及其修改均仅限一词; 2.只允许修改10处,多者(从第11处起)不计分。 Music and songs play a important part in our daily life.For examp
