406.The best and most beautiful things in the world cannot be seen or even touched—they must be felt with the heart. 世界上最美好的事物眼不能见、手不能碰触到——它们只能被用心感受。——Helen Keller
409.It's not just study that's difficult. You have to get used to a whole new way of life, which can take up all your concentration in the beginning. 困难不仅仅是在学习方面,你得适应一种全新的生活方式,在一开始这就会占去你的全部精力。
