解析
本题主要考查词汇的正确形式及词义辨析。解题思路如下:
- 对于第一个空,需要根据情态动词“can”的用法来确定动词形式。情态动词后面要接动词原形,所以这里应使用动词原形。
- 对于第二个空,根据句子结构,“has successfully”表明这是现在完成时,其结构是“have/has + 过去分词”,所以这里需要一个动词的过去分词形式。
- 接着分析各个选项的词义:
- “convert”意为“转变;转换”,“convert...into...”是固定短语,表示“把……转变成……”。
- “revolutionized”是“revolutionize”的过去式和过去分词,意为“彻底改变;使革命化”,但它一般不用于“revolutionize...into...”这样的结构。
- “exchange”意为“交换;交流”,不符合此处语境。
下面进行具体分析:
- 第一个空:因为“can”是情态动词,后面接动词原形,所以应选“convert”。
- 第二个空:现在完成时需要动词的过去分词,“convert”的过去分词是“converted”,所以选“converted”。
