[辨析] none 和no one
none 和no one 都可意为“没有人”, 意思虽然相同, 但用法却不同。
(1) none作不定代词, 既可指人, 也可指物, 后可接of结构；而no one只表示人, 后面不能接 of结构。
(2) none作主语, 指可数名词时, 后面动词用单复数均可；none指不可数名词时, 谓语动词用单数。no one 作主语时, 谓语动词要用单数形式。如：
爱德温·艾尔德林
环绕地球飞行的宇航员每“天”可以看见16次日出和16 次日落。
1986年1月28日, “挑战者”号航天飞机在肯尼迪航天中心发射升空不久后爆炸。
Let’s learn something about Chinese space program.
Who is he? He is China’s first astronaut.
2.The Sun is a star. √
3.There is more than one galaxy in the universe. √
4. The light from stars in other galaxies has travelled for a long time to reach us. √
____A____ of the reasons was true. A. None C. Nothing B. No one D. All
4. It is impossible to imagine.

4. Have we discovered other galaxies in the universe?

Module 3 Unit 2 We haven't found life on other planets yet_王述文

Module 3 Journey to spaceUnit 2 We haven’t found life on other planets yet.一、教材内容分析本模块以人类探索宇宙的行为为背景引入现在完成时的用法，通过人类对宇宙太空所做努力的描述强化现在完成时的表意功能，开展听说读写教学活动。

教学内容为语法的学习和使用提供了必要的感性材料。

本模块的中心话题是介绍航天知识，着重介绍了火星探索计划以及宇宙中太阳系的部分知识。

要求学生能够了解一点航天知识，学会利用现在完成时描述人类已经实施的太空探索计划。

二、学情分析在前一个模块“Experiences”的学习中，学生初步掌握了利用现在完成时态谈论旅游、看电影、看书等经历，学习了现在完成时的一般疑问句及肯定、否定的回答方法。

在本模块中，学生将继续学习yet, already, just等词在现在完成时态中的用法及have been to与have gone to之间的区别。

人类探索宇宙，是否真的存在外星人，太空旅行……这些一直都是学生们非常感兴趣的话题，学生会觉得有话可说。

但是在讨论这一话题时将涉及较多的专有名词，学生掌握的难度较大。

所以如果教材内容处理不当，会导致学生有话想说，却无法用英语来表达的尴尬场面。

因此在具体安排教学内容时，应注意适当降低难度与要求，通过开展生动有趣的活动将航天知识深入浅出的传授给学生。

三、教学目标国家«英语课程标准»指出，教学的开展应该激发和培养学生学习英语的兴趣，使学生树立自信心，养成良好的学习习惯和形成有效的学习策略，发展自主学习的能力和合作精神。

在教学过程中要努力培养学生的观察、记忆、思维、想象能力和创新精神。

依据这些要求，我制订了本模块的教学目标：1．语言技能目标（1）能够听懂对火星计划的陈述。

（2）能够介绍人类对太空的探索经历。

/d/2005-10-18/1611742414.shtml（3）能够读懂有关太空话题的文章，掌握文章的大意。
