试题答案
76.解析:science→scientific。应该用形容词作定语。
77.解析:planet前加the。planet前用定冠词,特指Mars。
78.解析:去掉be。can rise在本句中表“气温上升”。
79.解析:sun→sun’s。名词所有格作定语,修饰heat。
80.解析:drops后加to。drop to表“下降到”。
81.解析:some→any。在表否定意义的副词hardly后面用any, hardly any oxygen意为“几乎没有任何氧气”。
82.解析:and→or。此处表选择关系。
83.解析:working后加on。work on是固定词组,表“研究”。
84.解析:make→makes。本句的主语是名词cost, 故谓语动词用单数形式。
85. √。
