【小题8】until
【小题9】fear

【解析】（1）reached.考查动词。

根据上文
"There once lived a beautiful white elephant in the forest"可知，森林里生活着一头美丽的白
象。

消息传到国王那里。

reach是动词，意思是"到达"，此处用其过去式，表示过去发生的事情，故填reached。

（2）himself.考查代词。

此处的介宾和主语是同一人，故用反身代词himself,表示"他自己"。

句意：国王希望自己拥有这头大象，于是他请人去寻找这头大象。

故填himself。

（3）After.考查介词。

根据句中"a year"可知，应填介词after,和后面的名词组成介宾结构，充当时间状语，表示"过了一年后"，即过了一年后，国王的人发现了大象居住的地方，于是把它带到国王那里。

故填After。

（4）to train.考查不定式。

根据语境可知句意是，他请仆人去训练这头大象。

train训练。

本句是ask sb to do sth句型，意思是"请某人做某事。

故填to train。

（5）difficult.考查形容词。

根据上文"He asked his men （4）the elephant."可知，他请仆人去训练这头大象。

但是这很难，于是那些人经常抽打它。

difficult是形容词，意思是"困难的"，在此作为表语。

故填difficult。

（6）way.考查名词。

根据上文" One day, the elephant tried hard to run away"可知，有一天，大象奋力逃走了。

它成功地逃进树林。

make one's way成功；想方设法；前往。

故填way。

（7）Luckily.考查副词。

根据上文
"She ran for months, fearing the king's men might follow and find her"可知，它逃走了数月，害怕国王的人会尾随而来找到它。

幸运的是，国王的人没有来。

luckily是副词，作为状语，意思是"幸运的是"。

故填Luckily。

（8）until.考查连词。

根据句中"didn't"可知，应填连词until,意思是"直到"，即本句是"not…until"句型，意思是"直到……才"。

句意：直到非常疲倦了它才停下来。

故填until。

（9）fear.考查名词。

根据下文"The tree could feel her great fear"可知，在恐惧中跑了数小时后，大象停在一棵老树边。

大树能够感觉到他的恐惧。

fear是不可数名词，意思是"害怕"。

in fear在恐惧中。

故填fear。

（10）what.考查代词。

根据语境可知句意是，大象立刻明白了树木告诉它的是事情。

what是代词，意思是"什么"，在此引导宾语从句，并且在从句中充当直接宾语，表示告诉的内容。

故填what。

本文用大象逃跑的事例说明，人们有恐惧是思想的问题，而不是外界我原因。

首先要通读短文，掌握大意，特别要注意上下文之间的联系，确定某处的需要的词汇和形式，就可以确定正确答案．
26.【答案】【小题1】others
【小题2】has
【小题3】online
【小题4】daily
【小题5】others
【解析】（1）online,daily.词义替换题。

根据on the internet在网上，可知同义词为online 在线；everyday每天，同义词为daily每天。

故答案为：online,daily.
（2）others,has.推理判断题。

根据上文
While some people have found great joy in using the app,有一些人在使用app时找到了很大的乐趣，下文主语应为另一些人，用others来表示；主语为It,空后宾语为new functions 新功能，可能判断出是它有新的功能，有have,这里用动词的单三形式。

故答案为：others,has.
（3）It′s really a waste of time.汉译英。

根据浪费时间a waste of time,这用it来指代，真的really,可以完成一个句子。

故答案为：It′s really a waste of time.
（4）Although,in.句式转换题。

根据原句
Apps like Douyin may bring us joy, but we should use them properly.像抖音一样的App可以给我们带来快乐，但是我们应该合理地使用，这里用but表示转折的上下文关系，所以用although虽然来改写，符合题意；properly恰当地，可用in a proper way用一种恰当的方式来表示。

故答案为：Although,in.。

（5）apps.主旨大意题。

根据文章第一句和最后一句可知，都提到了apps这个词。

故答案为：apps.
文章讲述了随着手机app的发展，人们有了更多的机会用共享视频通过在线的方式与世界上的其他人沟通。

这是个综合型阅读题，题目中有英汉互译题、也有问答题，主要考查学生的阅读理解能力及知识运用能力．答题时细节理解题可直接根据文中细节得出答案；第（2）小题要根据代词所在的具体语境来推测代词指代的含义；英汉互译题需要根据句意及汉英语言各自的语法习惯来翻译；而主观发挥题则要联系文章内容进行适当发挥．
