翻译原文:Relational databases are used where associations among files or records cannot be expressed by links; a simple flat list becomes one table, or “relation”, and multiple relations can be mathematically associated to yield desired information. Object-oriented databases store and manipulate more complex data structures, called “objects”, which are organized into hierarchical classes that may inherit properties from classes higher in the chain; this database structure is the most flexible and adaptable.
翻译答案:当文件或记录间的关系不能用链表达时,使用关系型数据库。一个表或一个“关系”,就是一个简单的非结构列表。多个关系可通过数学关系提供所需信息。面向对象的数据库存储并处理更复杂的称为对象的数据结构,可组织成有层次的类,其中的每个类可以继承层次链中更高一级类的特性,这种数据库结构最灵活,最具适应性。
读完一本书原文:As much as I tried to tell myself that I hadn't asked her for the eggs—I hadn't said we wanted them or needed them or liked them—the fact was, I'd
never seen Juli cry before. Not when she'd broken her arm in P.E., not when she'd been teased at school or ditched by her brothers. Not even when they'd cut down the sycamore tree. I'm pretty sure she cried then, but I didn't actually see it.
To me, Juli Baker had always been too tough to cry.
I went down to my room to pack my stuff for school, feeling like the biggest jerk to ever hit the planet. I'd been sneaking around throwing out eggs for over two years, avoiding her, avoiding my father — what did that make me? Why hadn't I just stood up and said, No thanks, don't want 'em, don't need 'em, don't like 'em…. Give them to the snake, why don't you? Something!
Was I really afraid of hurting her feelings?
Or was I afraid of her?
翻译答案:我只是努力的说服自己,并不是我开口问她要那些鸡蛋的--我从来没有说过我们想要,需要或者是喜欢它们--事实上,我从来没见朱莉哭过。不管是体育课上摔断了手臂,还是在学校被别的孩子欺负,或者被她的哥哥们戏弄。即使他们砍倒了无花果树的时候她也没哭。刚才,我可以肯定她哭了,但我并没有真的看见她的眼泪。对我来说,朱莉.贝克那么坚强,不可能掉眼泪。
我回到自己的房间收拾上学用的东西,感到自己是地球上有史以来最糟糕的浑蛋。我躲着她,躲着爸爸鬼鬼祟祟地扔鸡蛋扔了两年--我成了什么了?我为什么不能站起来说,不要再送了,谢谢你,我们不需要,我们不喜欢。。把它们留给蛇吃吧,为什么不告诉她?说什么都可以!
难道我真的害怕伤害她的感情?
或者,我害怕的是她?
