1. 展示课前收集的各国著名科技成果的图片,介绍并讨论。
答案：【解析】：此题并非一个传统的数学、物理或化学等科目题目，而是一个英语文化时间（Culture time）相关的教学活动描述。题目要求展示课前收集的各国著名科技成果的图片，并进行介绍与讨论。这主要是考察学生的英语表达能力、课前准备情况以及对科技成果的了解和讨论能力。由于是英语教学活动，重点会放在学生用英语描述科技成果的准确性和流利度，以及他们在讨论中展现的批判性思维和合作能力。
此题不涉及具体的数学公式或科学计算，而是侧重于语言运用和文化知识的展示。因此，解答此题的关键在于学生能否有效地用英语传达科技成果的相关信息，并在讨论中展现出对科技话题的深入理解和思考。
【答案】：由于这是一个教学活动描述，而非传统意义上的题目，因此没有具体的答案。不过，一个可能的回答框架如下：
1. 图片展示：我会展示我收集到的各国著名科技成果的图片，如中国的5G技术、美国的SpaceX火箭、欧洲的核聚变实验装置等。
2. 介绍：我会用英语简要介绍每项科技成果的背景、意义以及它对人类社会的影响。例如，“This is a picture of SpaceX's Falcon rocket. SpaceX has made significant advancements in reusable rocket technology, reducing the cost of space travel and opening new possibilities for space exploration.”
3. 讨论：在讨论环节，我会与同学们分享我对这些科技成果的看法，并听取他们的观点。我们可以探讨这些技术如何改变了我们的生活，以及它们对未来可能产生的影响。
