1. What new scientific developments do you expect to see in the next ten or twenty years?

这道题目让考生预测未来的发展趋势。首先要搞清楚都有哪些科技领域，如生命科技领域、空间科技领域、信息科技领域等。考生可以泛泛而谈，也可以抓住一点。关键注意是new developments，一定要突出一个“新”字，即当今技术还处于雏形，未来可能走向成熟。

Candidate 1: There are many scientific developments I expect to see in the next ten or twenty years.

Firstly, I hope that one day in the next ten or twenty years scientists could find effective ways to cure cancer. It is horrible to see millions of patients who suffer from cancer and died because of the fatal disease. If the doctor can conquer the cancer, people around the world would respect him or her and give him or her the highest honor. The patients would not suffer a lot and the relatives and friends would not sustain the distress because of their relatives' leaving.

Secondly, I expect scientists would overcome the technical problems and support people to live on the moon. How fantastic the thing is! If human beings could live on the moon, we can experience a different style of life and broaden our horizons. Meanwhile, living on the moon can relieve the earth's pressure.

The above is what I expect to see in the next ten or twenty years.

Candidate 2: With the development of science, great changes will take place in our daily life. There will be more and more advanced equipment, beautiful scenery, etc., but there will also be unfavorable things happening in the next ten or twenty years. It looks like a flash that no one could predict exactly what the future will become.

However, in the next ten or twenty years I expect there will be some breakthroughts in medical area. I do hope to see that there will be a new drug which could cure the AIDS completely in the next ten years or twenty years. As we all know, AIDS is one of the most incurable diseases in the world and the number of AIDS patients is increasing sharply every year in our country. Seeing so many happy families are destroyed by AIDS on TV, I am eager to see a new drug could be invented to cure these people who were infected with AIDS. Not only does it kill some energetic adults but also some innocent children, who just set their feet on lives. The moment I think of the torture of some children who are infected with HIV and suffering, there is always a great pain in my deep heart. Such a precious small life has to say "goodbye" gradually to the beautiful world! I wish that I can do something to relieve their pains! But I can not save their lives...

Therefore, as a student of Peking University, I expect to see a new drug will be invented to save more and more AIDS patients' lives in the next ten or twenty years.

Candidate 1预测了未来科技发展的两个方面。第一，未来的科学家能够找到更好的治疗癌症的方法。第二，人们能够登上月球居住；Candidate 2重点预测了未来医学领域的发展与突破。人们会找到治愈癌症的有效的办法，从而减轻艾滋病患者的痛苦，拯救他们的家园。
