By the year 2015, the clothing industry will have produced new types of material that will remain stainless no matter what you spill on them. 2015年之前，服装工业将生产出新型的材料，不管你将什么东西洒在上面，都不会留下污点。
结构分析: 整句是一个较复杂的主从复合句。that will remain stainless…是定语从句，定语从句中又有由no matter what引导的让步状语从句。顺便提提，”by+将来时间”常与将来完成时连用，本句中主句的谓语will have produced就是将来完成时。
学以致用：用no matter what翻译下列句子。
无论什么时间，你到了那儿就给我打电话。
_____________________________________Call me when you get there, no matter what
the time is.2. By the year 2030, development in biochemistry and medical science will have made it theoretically possible for us to live for at least 150 years. 2030年之前，生物化学和医学的发展将能够在理论上使人类至少活到150岁。
结构分析: 该句中的it是形式宾语，真正的宾语是其后的不定式复合结构for us to live for at least 150 years，possible用作宾语补足语。能用于make it + adj. + for sb. to do sth.句型的还有think, consider, feel, find等动词。
学以致用：用make it possible for sb. to do sth.翻译下列句子。
中国经济的快速增长使得农村孩子享受真正的免费义务教育成为可能。

结构分析: 本句中的not to mention sth.意为“更不用说”，相当于介词的用法，用于句末补充信息。类似的表达还有：not to speak of, to say nothing of, let alone（用作连词）等。如：The little child can’t walk, let alone run / not to mention running. (这小孩连走都不会，更不用说跑了)
学以致用：用not to mention sth.翻译下列句子。

结合本单元句型，并运用部分重要词组，如as we all know, it is the first time that clause, send up, look back on, dedicate…to…, contribute…to…, take place, result from, so as to等，根据以下所提供的关于中国航天事业发展的资料，写一篇演讲稿：
1. 1970年，第一颗人造地球卫星“东方红1号”成功发射；
2. 2003年10月15日，我国成功发射了“神舟五号”载人航天飞船，杨利伟成为“中国太空第一人”；
3. 2005年10月12日，“神舟六号”载人飞船成功发射，首次将我国两名航天员同时送上太空；
4. 2007年10月24日，“嫦娥一号”成功发射，开始了奔月之旅。Dear fellows,
As we all know, October 24th, 2007 was one of the most exciting days for all Chinese people. The spaceship “Chang’e I” was launched successfully on this day.
Looking back on our spaceflight development, we can find many scientists have dedicated all their lives to their research. In 1970, the first man-made satellite named “Dongfanghong I” was sent up, which realized millions of Chinese people’s dream of flight. A milestone flight took place in 2003 when “Shenzhou V” was successfully launched. It was the first time that a spacecraft carried a Chinese astronaut into space. In 2005, another two astronauts were sent into space. All these achievements show that China has become a strong nation of space exploration. As a Chinese, I feel very proud, but I also know that every success results from hard work and behind success are tears and sweats. As middle school students, we should learn from them and study even harder so as to contribute even more to our motherland.
That’s all. Thank you.
goodbye
