試題內容

    Cubes aren't usually the go-to shape when creating an object that's meant to move around, but___1__in Switzerland have created one that can do just that—along with a__2__of other surprising talents. Called the Cubli, it measures nearly 6 inches oneach side and can walk around by__3__flipping itself over. Perhaps more impressively, itcan also balance on any of its sides or even just a single corner. As the research team fromETH Zurich's Institute for Dynamic Systems and Control__4__in a video, the cube caneven remain balanced while a surface is raised up at an angle beneath it.
    Though it's a moving cube, the Cubli still__5__on a series of spinning wheels to getgoing. Three internal wheels angled along a different axis each will spin faster or slower inorder to maintain enough momentum to keep the cube balanced. By quickly__6__a spinningwheel, the cube can also be caused to flip over,__7__allowing it to move around. Theresearchers say that Cubli's system of spinning wheels is similar to what__8__ satellitesout in space, and that other research groups have considered using this technology to buildrobots that could be used to explore other planets.
    A group of researchers at MIT later demonstrated another use for__9__like this:allowing a robot to reassemble itself. MIT's cubes had magnets embedded across theirsides and edges, which let them grip each other and form different shapes. Though theyweren't able to balance like the Cubli can, MIT's "M-blocks" could move much__10__actually hopping offthe ground when getting around.

1.[選詞填空]
    • 解題思路:名詞辨義題。此處空格所在的句子缺乏主語,而謂語是have created,由此可以判斷,此處需要填入一個復數名詞。備選詞匯中只有researchers“研究人員”符合此處語境,故選L。
    2.[選詞填空]
      • 解題思路:動詞辨義題。空格所在的分句缺少謂語動詞,依據該分句的主語theCubli可以判斷此處應該填入一個動詞的第三人稱單數形式,且須能與介詞0n搭配使用。備選詞匯中只有relies“依靠”符合此處語境.故選K。
      3.[選詞填空]
        • 解題思路:動詞辨義題。根據空格前的By quickly和空格后的a spinning wheel可以判斷,此處需要填入一個動詞的現在分詞形式,且意義上要能與awheel構成關聯。備選詞匯中只有halting“停止”符合此處語境,故選G。
        4.[選詞填空]
          • 解題思路:副詞辨義題。空格所在的分句作整個句子的狀語,而此處空格后緊接的就是現在分詞allowing,由此可以判斷此處要填入一個表示積極意義的副詞修飾allowing。備選詞匯中只有effectively“有效地”符合此處語境,故選E。
          5.[選詞填空]
            • 解題思路:名詞辨義題。根據空格前的another use for和空格后的like this可以判斷,此處需要填入一個名詞。空格后的this指代的是前文中提到的小方塊,故而可以判斷空格處填入的名詞需要與“小方塊”類似。備選詞匯中只有blocks符合此處語境,故選A。
            6.[選詞填空]
              • 解題思路:根據空格前的could move much可以判斷,此處需要填入一個副詞修飾move。備選詞匯中只有further“更遠地”符合此處語境,故選F。
              7.[選詞填空]
                • 解題思路:副詞辨義題。從空格所在句的結構來看,此句并不缺乏任何句子成分,再由空格后的flipping itself over可以判斷,此處只能填入副詞修飾flipping。flip over為固定搭配,意為“(使)突然翻轉”。備選詞匯中,continually“不斷地”最符合此處語境,故選B。continually flipping itself over意為“不斷地自我翻轉”。
                8.[選詞填空]
                  • 解題思路:動詞辨義題。根據空格前的is similar to what和空格后的satellites outin space可以判斷,此處需要填入一個動詞的第三人稱單數形式,且意義上須能與satellites構成關聯。備選詞匯中只有stabilizes“使穩固”符合此處語境,故選N。
                  9.[選詞填空]
                    • 解題思路:動詞辨義題。空格所在的分句缺少謂語動詞,該分句的主語為theresearch team,而上下文采用的時態都為一般現在時,由此可以判斷此處需要填入一個動詞的第三人稱單數形式,且意義要能與a video構成關聯。備選詞匯中只有demonstrates“演示”符合此處語境,故選D。
                    10.[選詞填空]
                      • 解題思路:名詞辨義題。根據空格前的不定冠詞a和空格后的介詞of可以判斷,此處需要填入一個單數名詞。備選詞匯中只有handful“少數,少量”符合此處語境,故選H。ahandful of為習慣用法,意為“少數的,少量的”。
