If I walk in the mud (泥土), it will cover up my feet. I look around here, and no one can compare with me. I am the owner of this well. My dear sir, why don’t you come over and look around my place?”Then the turtle told the frog about the East Sea.“You have no idea how large and how deep the sea is. In the past thousands of years, there were floods (洪水) for many years, but the water in the sea did not become more. And when it was dry for many years, the water in the sea didn’t become less. The sea does not change with time and it does not rise or fall as the rain falls, either. The greatest happiness is to live in the East Sea.” After hearing this, the frog was shocked.There is always someone better than you; there is always something greater than you know.

(补全英语句子)She called me _________ _________ _________ she left home yesterday.参考答案1．D【解析】句意：暑假一开始我就去参观长城。

A. since自从；B. while正当……的时候，然而；C. until直到；D. as soon as一……就。

as soon as引导的时间此句遵循“主将从现”的原则，结合句意可知，答案为D。

2．B【解析】句意：他当他第一次来这的时候，他就爱上了这个城市。

短语fall in love with…表示爱上……。

根据题意，故选B3．A【解析】句意：他必须努力工作挣很多钱，这样他才能过上富裕的生活。

so that= in order that 都可以引导目的状语从句，that只能引导宾语从句和定语从句；such that 只能分开写，引导结果状语从句，结合句意，故答案只能选A。

点睛：such…that…与so…that…都可以用来引导结果状语从句，意为“如此…以致…”。

such是形容词，它所修饰的名词可以是可数名词，也可以是不可数名词；名词前面可以带形容词，也可以不带。

如果其后是单数可数名词，前面需加不定冠词a或an。

如：She is such a good teacher that all of us love and respect her.她是一位很好的老师，我们都敬爱她。

They are such interesting books that I want to read them once more.这些书非常有趣，我想再读一遍。

so是副词，与形容词或副词连用，其结构是：so+ adj.(adv.)+that从句。

如：He ran so fast that I couldn’t catch up with him.他跑得那么快，我赶不上他。

I am so sleepy that I can hardly keep my eyes open.我太瞌睡了，眼睛几乎睁不开了。

so that引导目的状语从句，表示“以便；为了”，如：He got up very early so that he could catch the train．他起得很早以便能赶上火车。

4．C【解析】表示“结婚多长时间”要用be married，再结合现在完成时的结构可知答案为C。

5．D【解析】由than before可知要用比较级，先排除A和C；再结合题干中的“他从不锻炼，吃太多垃圾食品”可知，他变得比以前更“虚弱”，故weaker符合题意。

6．B【解析】试题分析：句意：当他们听到这个令人激动的消息，每个人都很兴奋。

exciting: adj. 令人兴奋的, 使人激动的，主语是物或事；excited: adj.兴奋的：处于激动状态的；兴奋的；激昂的，主语为人较多。

故答案为B。

考点：考查形容词辨析。

7．B【解析】句意：——我们明天去森林公园野餐怎么样？——可以，除非下大雨。

本题考查连词的用法。

if如果；unless除非；until直到；when当……时候。

结合句意可知，此处应选unless。

8．A【解析】句意：你的叔叔一到这里就会来看你。

as soon as引导时间状语从句，主句是一般将来时，从句要用一般现在时。

故答案为A。

9．B【解析】try to do sth尽力做某事。

10．C【解析】unless=if…not“如果不”之意，构成复合句时，常遵循“主将从现”的原则。

11．12．magic13．14．monkeys15．16．weak17．18．smiles19．20．objects【小题6】【小题6】stupid【小题7】【小题7】ground【小题8】【小题8】gold【小题9】【小题9】brave【小题10】【小题10】inside【解析】11．12．句意：孙悟空有魔力棒。
