世界上一些国家都在制订高科技发展计划，中国也制订了高科技发展计划。
Some countries are drawing up plans for the development of high technology.
China has done so too.
下一个世纪是高科技发展的世纪。
The next century will see rapid development.
说起我们这个正负电子对撞机工程，我先讲个故事。
As for the electron-positron collider, first I want to tell you a story.
如果六十年代以来中国没有原子弹、氢弹，没有发射卫星，中国就不能叫有重要影响的大国，就没有现在这样的国际地位。
If it were not for the atomic bomb, the hydrogen bomb and the satellites we have launched since the 1960s, China would not have its present international standing as a great, influential country.
这些东西反映一个民族的能力，也是一个民族、一个国家兴旺发达的标志。
These achievements demonstrate a nation's abilities and are a sign of its level of prosperity and development.
现在世界的发展，特别是高科技领域的发展一日千里，中国不能安于落后，必须一开始就参与这个领域的发展。
The world is developing; in particular, high technology is advancing at a tremendous pace.
China must not be content to remain backward.
It should participate in the development of high technology from the very beginning.
搞这个工程就是这个意思。
That is the purpose of this project.
还有其他一些重大项目，中国也不能不参与，尽管穷。
As for other major projects, although China is poor, it has no choice but to undertake them.
因为你不参与，不加入发展的行列，差距越来越大。
Because if we don't, the gap between China and other countries will grow wider.
当然，有李政道和其他国际朋友的帮助，使我们少走弯路。
It is true that with the help of Tsung-Dao Lee and other international friends, we were able to avoid detours.
但是这个工程不完全是照搬过来的，中间也还有我们自己的东西，有自己的技术，有自己的创造。
But this project was not merely copied from a foreign country: some of the equipment and technologies involved in it were developed by Chinese engineers.
总之，不仅这个工程，还有其他高科技领域，都不要失掉时机，都要开始接触，这个线不能断了，要不然我们很难赶上世界的发展。
In short, we must waste no time in launching high technology projects like this one and we must carry them through to completion.
Otherwise, it will be very difficult for us to keep up with advances in the rest of the world.
