本题为英语单词适当形式填空题,需结合句子结构、固定搭配、时态语态、词性转换规则确定单词的正确形式。解题思路:先分析句子成分判断所需词性,再结合时间状语、主被动关系确定时态语态,最后依据固定短语、特殊结构匹配对应形式。
【解析】
1. 需形容词作表语,be gone是固定短语,意为“消失的”,故填gone。
2. 固定搭配allow sb to do sth(允许某人做某事),故填to live。
3. 由时间状语in the past可知用一般过去时,主语wild animals与动词trouble是被动关系,故用一般过去时的被动语态were troubled。
4. 修饰动词grow需用副词,free的副词形式为freely,故填freely。
5. 修饰名词ecosystem需用形容词,balance的形容词形式为balanced(平衡的),故填balanced。
6. 作主语需用名词,pollute的名词形式为pollution(污染),air pollution意为“空气污染”,故填pollution。
7. 介词of后接动名词,且trees与cut是被动关系,故用动名词的被动式being cut,填being cut。
8. too many后接可数名词复数,tour表示“游客”的名词复数为tourists,故填tourists。
9. 固定结构there be sth to do(有某事要做),不定式作后置定语,故填to do。
10. 固定搭配permit sb to do sth(允许某人做某事),故填to break。
【答案】
1. gone 2. to live 3. were troubled 4. freely 5. balanced 6. pollution 7. being cut 8. tourists 9. to do 10. to break

5. have her way 6. cutting down 7. take back 8. start over

解析

【分析】
首先通读全文,理解文章主旨为探讨人类消失后地球的变化,需结合每个空的上下文语境、语法规则(时态、非谓语、虚拟语气等),从方框短语中选择并调整正确形式。具体思路:1. 第一空为if虚拟语气对现在的假设,从句用一般过去时,结合语境选stand still的过去式;2. 第二空由时间状语for a long time确定用现在完成时,短语leave marks on符合人类对地球的破坏语境;3. 第三空描述过去的动作,用一般过去时,care for体现对生态的态度;4. 第四空为learn to do结构,get along with符合与自然和平相处的语境;5. 第五空在would后接动词原形,have her way体现自然恢复自身状态;6. 第六空前是形容词endless,需接动名词,cutting down符合砍伐树木的语境;7. 第七空在would后接动词原形,take back体现森林收回土地;8. 第八空在can后接动词原形,start over体现重新开始的含义。
【解析】
1. 考查虚拟语气。if引导对现在事实相反的虚拟条件句,从句用一般过去时,方框中stand still(此处指人类生命消失)的过去式为stood still,符合语境,故填stood still。
2. 考查现在完成时。时间状语for a long time是现在完成时的标志,短语leave marks on(留下痕迹),主语humans为复数,故填have left marks on。
3. 考查一般过去时。描述过去的动作,短语care for(关心),此处指人类从未真正关心生态平衡,用过去式cared for,故填cared for。
4. 考查非谓语动词。learn to do sth是固定结构,短语get along with(与…相处),此处指学会与自然和平相处,故填get along with。
5. 考查情态动词用法。would后接动词原形,短语have her way(随心所欲),此处指自然会恢复自身状态,故填have her way。
6. 考查非谓语动词。形容词endless后接动名词,短语cut down(砍伐),endless cutting down trees意为“无休止的砍伐树木”,故填cutting down。
7. 考查情态动词用法。would后接动词原形,短语take back(收回),此处指森林收回人类占据的土地,故填take back。
8. 考查情态动词用法。can后接动词原形,短语start over(重新开始),此处指世界不是可以随时重新开始的游戏,故填start over。
【答案】
1. stood still 2. have left marks on 3. cared for 4. get along with 5. have her way 6. cutting down 7. take back 8. start over
【知识点】
动词短语;时态运用;虚拟语气

本题为选词填空题,主要考查常用动词短语的辨析及在语境中正确运用短语的适当形式,涉及虚拟语气、时态、非谓语等语法知识,需结合上下文逻辑和语法规则完成,难度适中。
