本题主要考查对所给短语的理解和运用，需要根据句子的语境和语义来选择合适的短语，并在必要时对短语形式进行调整。

1. “_____ the chat program, QQ has also developed sub - features like games, pets, ringtone downloads, etc.”
   • 解题思路：此句表达QQ除了聊天程序之外，还开发了其他功能。“aside from”有“除……之外”的意思，符合句子语境，所以应填“Aside from”。
2. “The number of students participating in online courses varies _____.”
   • 解题思路：句子要表达参加在线课程的学生数量每年都在变化。“year to year”表示“逐年；每年”，能准确表达这种时间上的变化情况，所以填“year to year”。
3. “When people communicate face to face, 60 - 70 percent of the meaning is _____ the non - verbal cues such as gestures and facial expressions.”
   • 解题思路：这里说的是当人们面对面交流时，60% - 70%的意思是从非语言线索中获得的。“derive...from”表示“从……中获得；源自”，句子是被动语态，所以用“derived from”。
4. “Which emoji would you _____ as the most useful one in your daily communication?”
   • 解题思路：此句询问在日常交流中会挑选出哪个表情符号作为最有用的。“single out”有“挑选出；选出”的意思，符合句子语义，所以填“single out”。
5. “Recently his grandfather has _____ surfing the Internet for health information.”
   • 解题思路：句子表示最近他的祖父开始上网查找健康信息。“take to”有“开始从事；喜欢上”的意思，“has + 过去分词”构成现在完成时，“take”的过去分词是“taken”，所以填“taken to”。
6. “Unless you have a good literary agent, your script will never _____.”
   • 解题思路：该句意思是除非有一个好的文学经纪人，否则剧本永远不会问世。“see the light of day”表示“问世；出版；公开”，符合句子语境，所以填“see the light of day”。
