考生普遍认为科学是一个很难的话题。我个人认为它确实有些难度，但并不是可怕到无话可说的地步。科学分为很多种，生物，植物，物理，化学 大家从其中某一门学科中挑选一个比较生活化，比较通俗易懂的用英文描述出来就可以了，并不需要说那些深奥的科学问题如：外太空黑洞，磁铁的两极，无机化学命名等等。 下面挑选一个科学实验的例子，提供一些素材给大家，其实还有很多可以选择，时间关系，先去上课，晚上回来再给大家补充关于生物和植物方面的口语素材。 Describe a science lesson that you had in school or university. You should say: when you attended this lesson where you attended this lesson how you learned it and explain what you learned. Boiling Frog 温水煮青蛙 how you learned it The boiling frog story states that a frog can be boiled alive if the water is heated slowly enoughit is said that if a frog is placed in boiling water, it will jump out, but if it is placed in cold water that is slowly heated, it will never jump out. If you put the frog in cold water and slowly increase the temperature--slowly boil the water, the frog will be cooked without trying to jump out. |
