当实验开始的时候,整个班级都很兴奋。我们把油、水和碱液混合在一起。你必须非常小心,因为碱液会腐蚀皮肤。然后我们就开始搅拌液体。大约10分钟过后,发生的化学反应就把液体变成了固体,肥皂就形成了。虽然这个过程很累,但是我们得到了很多乐趣。最重要的是我们学会了如何制作肥皂。时间过得太快,我们感觉很忙碌,但也学到了很多有用的东西。
篇四:
I have nothing to offer but blood, toil, tears and sweat. We have before us an ordeal of the most grievous kind. We have before us many, many months of struggle and suffering. You ask, what is our aim? I can answer in one word, it is victory. Victory at all costs—victory in spite of all terrors—victory, however long and hard the road may be, for without victory there is no survival. Let that be realized, no survival for the British Empire, no survival for all that British Empire has stood for , no survival for the urge, the impulse of the ages, that mankind shall more forward toward his goal. I take up my task in buoyancy and hope. I feel sure that our cause will not be suffered to fail among men. I feel entitled at this juncture, at this time, to claim the aid of all and to say, “Come then, let us go forward together with our united strength.”
