【题目】阅读下面材料,在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

The truth 【1】________ trees are vital to our life is not a secret. They provide us with food, wood and most 【2________ (important), oxygen. Now there is one more thing we can add to this list—blocking out harmful bacteria from water.

The discovery 【3________ (make) by a team consisting【4________ scientists from the Massachusetts Institute of Technology (MIT) and high school students 【5________ were seeking a natural water filter—one that would help communities in developing countries that do not have access to modern water filter systems.

The 【6________ (research), led by Professor Rohit Karnik, decided to turn to trees for help 【7________ they could allow liquid to flow through, while blocking out air bubbles.

They began by cutting 1.5-inch-wide sections of tree bark from the branches of a white pine tree. The people related then tested the wood’s filtering ability by pouring water containing red dye particles of different sizes through. 【8________ their amazement, they found that it was effective in trapping all the articles. 【9________ (encourage), the team conducted 【10________ experiment, this time with water that contained bacteria. Sure enough, the sapwood held back 99% of the bacteria, allowing only 1% to flow through.

【答案】

【1】that

【2】importantly

【3】was made

【4】of

【5】who/that

【6】researchers

【7】because

【8】To

【9】Encouraged

【10】another

【解析】

试题分析:树木作用巨大。最新实验表明,它们能去除水中的细菌。

【1】that 考查同位语从句。此处是同位语从句,解释说明truth的内容,又因为从句中不缺少成分,故选用从属连词that。

【2】importantly 考查形容词和副词的转换。此处most importantly是在修饰谓语动词provide,故用副词。句意:它们为我们提供了食物和木头,更重要的是提供了氧气。

【3】was made 考查谓语动词的时态和语态。此处指上文中的新发现是由一个被几个科学家组成的队伍做出的the discovery和make之间是被动关系,故用被动语态。由本句话可知,用一般过去时。

【4】of 考查固定短语。consist of意为……组成,故填of

【5】who/ that 考查定语从句。先行词是students,并且students在后面的定语从句中充当主语,故用who/that。

【6】researchers 句子分析。分析该句结构可知,谓语动词为decided,那么能发出这个动作的主语应该为researchers研究人员,研究者。根据句意可知此处用名词的复数形式,故填researchers。

【7】because 考查状语从句。研究者决定向树求助,因为它们能流出液体。此处是原因状语从句,故填because。

【8】To 考查介词。 to one's amazement是固定结构,表示“令某人惊讶的是”。 举一反三:类似的用法有to one's delight令人高兴的是,to one's relief令人欣慰的等等。“to + one's + 情感名词”是英语中一个十分有用的结构,主要表示某人由于某事的发生而唤起其内心的某种情感,通常译为“令某人……的是”“使某人感到……的是”。

【9】Encouraged 考查非谓语动词。此处为分词作状语,主语team与encourage之间是动宾关系,故选用过去分词“encouraged”。

【10】another 考查代词。 根据上文可知关于此事做过实验,这次是除了上次以外的另一个实验,故用another,表示“另一个”。

【知识拓展】

to one's amazement,是固定结构,表示“令某人惊讶的是”。

举一反三:类似的用法有to one's delight,令人高兴的是, to one's relief,令人欣慰的等等。 “to + one's + 情感名词”是英语中一个十分有用的结构,主要表示某人由于某事的发生而唤起其内心的某种情感,通常译为“令某人……的是”“使某人感到……的是”。
