BACBD DACCD解析本文是一篇记叙文。通读短文可知，本文讲述的是H.L. Lipman 如何从日常生活中发明带橡皮头的铅笔的故事。短文第一句话就表明本文将要讲述的话题是how objects we use today came from simple ideas，然后通过讲述 H.L.Lipman发明带橡皮头的铅笔的故事来说明。文章隐含着教育意义；在日常生活中要做有心人，善于细心观察，开发自己的创新能力。1.本题的选择要注意上下文。四个选项均为动词，语法上都可填入，但文章说的是影响我们的生活和工作话题，即这些发明的东西改变了我们的生活方式，故选B.2.本题四个选项均为副词，但根据上下文可知：新发明是为了解决问题，使得做事情更容易，所以A符合语境。3.本段开始叙述H.L.Lipman的发明，讲述他是如何有这个注意的H.L.Lipman，的发明是观察中思考所得，而不是先有目标，故不能选B.4.从语法上看，本题四个选项均可做连词用，但从语义上来说这里是承接关系，必须用and来连接三个宾语:pencil, paper, eraser故选B.5.从上下文可知，写作时他需要修改。6.这样他就经常需要在书本下把橡皮找出来。本题同时考词义辨析，四个选项都与“看有关，但只有表示“找出，找到。”7.“我想让橡皮固定在一个地方（place）（便于寻找）”这是H.L.Lipman的想法。8.这个地方当然是在笔头上最方便了，所以H.L.Lipman在铅笔的一端刻出(cut)一个凹槽了9.他考虑到别人也需要这种铅笔，就把自己的设计（design）出售了。10.（因为他的设计被出售）很快这种带橡皮头的铅笔就普及。
