5、e been hard, made of metal and other rigid material. But a team of scientists at Harvard University in the US has managed to build an entirely soft robot one that draws inspiration from an octopus (章鱼). Described in science journal Nature, the Octobot could pave the way for more effective autonomous

6、 robots that could be used in search, rescue and exploration. The Octobot is minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots, the studys authors wrote. Robots built for precise, repetitive movements in a controlled environment dont do so well

7、 on rough terrains (地形) or in unpredictable conditions. And they arent especially safe around humans, because theyre made out of hard and heavy parts that could be potentially dangerous to their users. So researchers have been working on building soft robots for decades. Theyve taken inspiration fro

8、m nature, looking to animals from jellyfish to cockroaches, which are often made up of more flexible matter. But creating a completely soft robot remains a challenge. Even if engineers build a silicone (硅酮) body, its still a grand challenge to construct flexible versions of essential parts, such as

9、a source of power. Although soft robotics is still in its early stage, it holds great promise for several applications, such as search-rescue operations and exploration, Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technologys Center for Micro-Bio Robotics, wrote in a comment. S

15、 quite a common greeting. Body language is fascinating for anyone to study. People give away much more by their gestures than by _ (they) words.答案以及解析一、1.答案：intervened解析： 2.答案：inquire解析： 3.答案：distracts解析：4.答案：bother解析：5.答案：embarrassed解析：6.答案：distinguish解析：7.答案：perceive解析： 8.答案：occupied解析： 9.答案：tende

18、ronment dont do so well on rough terrains or in unpredictable conditions.以及本段内容可知,传统机器人无法在崎岖的地形上很好地运行,此外,由于沉重的金属部件,传统机器人可能会对人体产生伤害,据此可推断出,传统机器人的缺点是他们不能一直表现得很好。(3).细节理解题。根据倒数第二段中的Even if engineers build a silicone body, its still a grand challenge to construct flexible versions of essential parts, su

20、用于诸如搜索救援和探索等任务,故选B项。 三.答案：-of; spoken; what; which; are introduced; to relax; countries; Traditionally; expression; their解析：考查固定搭配。think of想到,想起。 考查过去分词作定语。spoken 意思为“口头的”,与后面的 written(书面的)一起作定语修饰words。考查宾语从句。从句what we call “body language”作of的宾语,同时what又作宾语从句中call的宾语,表示“的东西”。考查非限制性定语从句。设空处引导非限制性定语从句,

21、先行词为body language,表示物,关系词在从句中作主语,因此用which引导非限制性定语从句。注意:that不能引导非限制性定语从句。考查时态和语态。此处指当我们被介绍给陌生人时,又因为状语从句的时态一般要和主句的时态一致,主句为一般现在时,所以该空应该用一般现在时的被动语态。考查动词不定式。该句中的it为形式主语,因此后面应该用动词不定式作真正的主语。考查名词的复数。此处指亚洲国家中的问候,country为可数名词,由语境可知应用复数名词。考查副词。根据句子结构,此处应该用副词作状语,修饰整个句子。tradition为名词,其副词形式为traditionally。考查名词。定冠词the后面应该用名词形式。express的名词形式为expression。考查代词。由words 可以判断,此空应该填形容词性物主代词their。
