試題分析：
小題1:句意：它被用于捕捉太陽的射線。 be used to do sth. 被用于做某事。  
小題2:句意：就像孩子用小鏡子使陽光在墻上跳舞。 make +賓語+do sth. 使……做……。故此處用動詞原形dance。   
小題3:句意：太陽的光線在許多方面多很有用。根據They could light up可知此處是說陽光的和用途，又因位于be 動詞后用形容詞helpful。
小題4:句意：他們能在黑夜照亮城市。結合句意可知此處用名詞復數cities 。
小題5:句意：他們能融化海洋里危險的冰川。修飾icebergs in the ocean.可知大洋里的冰山容易讓船只翻船，因此是危險的，因修飾名詞icebergs故用形容詞dangerous。
