Activity 3:
The author's attitude to "reaching for the stars" is positive.
The reason is that the author states scientists believe visiting the stars is not a completely wild dream, and mentions ideas to make it possible (like letting astronauts sleep during the journey or developing faster spacecraft). Also, the author notes humans have achieved great things in space (such as landing on the moon and sending rovers to Mars), and thinks it seems likely that we may reach the stars one day.
1. [探究](1)do / carry out a survey
[应用]①did a survey
②surveyed himself

【分析】本题分为两部分：一是考查单词survey的词性、词义及用法，包括名词的固定搭配、动词的时态运用；二是考查对文本中作者态度的判断及理由阐述。对于survey相关题目，需牢记其作名词时“进行调查”的固定搭配，作动词时的含义，结合语境和时态变化填空；对于态度题，需从原文提取作者的相关表述，判断态度并组织理由。
【解析】1. Activity3：从原文可知，作者提到科学家认为探索星星不是完全空想，还列举了实现的可能方法，以及人类已取得的太空成就（登月、火星探测器），因此作者态度是积极的，理由围绕这些原文信息展开。2. 探究(1)：survey作名词时，“进行一项民意调查”的固定搭配为do/carry out a survey。3. 应用：①句为一般过去时，“做了一项调查”对应did a survey；②句为一般过去时，“审视自己”对应surveyed himself。
【答案】Activity 3: The author's attitude to "reaching for the stars" is positive. The reason is that the author states scientists believe visiting the stars is not a completely wild dream, and mentions ideas to make it possible (like letting astronauts sleep during the journey or developing faster spacecraft).
