分子、原子、粒子、中子、电子……这些基本的化学知识在美国教材中是怎么诠释的呢?You have learned that elements are madeof atoms and that an atom is the smallest unitthat has the properties of an element.Thismeans that once you split an atom,you do notget smaller pieces of the element.Instead,youget the particles that form all atoms.
You have learned that elements are made of atoms and that an atom is the smallest unit of things that has the properties of an element. Thismeans that once you split an atom, you do notget smaller pieces of the element.Instead, youget the particles that form all atoms.

从我家上溯三代,从祖父到父亲再到我,没有人擅长丹青。后来我师从永厚先生习书,先生首先是大画家,然后才是书家,他希望我学画:“我给你纸,给你颜料,你来画画。”老爷子的意思是,画画容易激发人的创造性,而书法很难走出前人的束缚。 “你写来写去,都是别人的,有什么意思。现在这些写字的,大多数是奴隶,没有自己的东西,都是按照别人的来,不是奴隶是什么?你得学学画画。” 我支支吾吾不说话。一来,我对画画不感
