The rainbow of knowledge;For more than ? of my life — 39 of my 50 years — I’ve either studied or taught in a school or a college in New York. either?…?or用于连接两个表示选择关系的名词或代词，意为“要么……要么”通常应连接两个相同性质的句子成分，但有时后一成分可能省略与前一成分相同的词。若连接两个成分作主语，其谓语通常与靠近的主语保持一致 我这辈子四分之三以上的时间（50年中有39年）是在纽约的中小学或大学里度过的，不是在上学，就是在教学。 1.?用“基数词＋序数词”表示 2.?如果分子大于1，分母则要用复数形式 3.?二分之一不能说?a(one)?second，而要说?a(one)?half 4.?分数修饰的名词在句子中作主语时，谓语动词是用单数还是复数取决于名词，即与名词保持一致 5.?带分数的表示：所谓带分数，实际上是“整数＋分数”，表达时分而述之，只是整数部分与分数部分要用连词?and?连接 6.?分数常和?of?连用，作主语或宾语，但分数也可以不带?of?短语直接作主语或宾语 ; You might think, then, that after all this time （我会了解一些情况） I’d have some grasp of the situation, that I’d actually know things — that（我会对知识和生活积极予以把握和肯定）I’d have some positive sense of assurance, of certainty, about knowledge and about life. But I don’t.

But then, modern physics tells us that reality itself is contradictory. The more scientists look into(调查，研究） our physical reality, the more it slips away from them. In a way（在某种程度上）, the more they learn, the less they know. ;Knowledge itself is contradictory. For example, picture your knowledge as a dot（点，小圆点）, as perhaps the period（句号） at the end of this sentence. Notice the tiny circumference（周线，周界） of that period, and let that represent the interface（交界处，边缘区域） of the known with the unknown —（换言之）in other words, your awareness of what you don’t know. ; But now imagine that little period（句号） growing, its blackness consuming（消耗，消费） more and more of the page. As it grows, so does its circumference（周线，周界）. And if that growing blackness represents（表现 ） knowledge, then as it grows, so does the awareness of what remains（继续，依然） unknown. In other words, the more you know, the more you know you don’t know. 但现在想象一下那个小小的句号在渐渐扩大，它的黑色部分占据页面越来越多的地方。随着它的扩大，它的周缘也跟着
