Many objects that people use each day started with a simple idea. These objects have often changed the way we  46 . Some help us to do a job more   47 . Others fill a need or solve a problem.
In 1858, Lipman had such an  48 . He took out a pencil, a piece of paper,   49 an eraser. Then he began to write. Sometimes he needed to  50  a word. Each time he had to search under his books and papers to   51  the eraser. “ I wish my eraser would stay in one 52 !” he said.
Then Lipman had his simple idea. He   53  a groove(凹槽) in one end of the pencil. He glued(粘牢) the eraser into the groove. Lipman had solved his problem. Later he thought that others might like to have such a pencil. So he sold his  54 .Some pencils with erasers were 55 . His design earned $ 100000.

本文是一篇記敘文。通讀短文可知，本文講述的是H.L. Lipman 如何從日常生活中發(fā)明帶橡皮頭的鉛筆的故事。短文第一句話就表明本文將要講述的話題是how objects we use today came from simple ideas，然后通過講述 H.L.Lipman發(fā)明帶橡皮頭的鉛筆的故事來說明。文章隱含著教育意義；在日常生活中要做有心人，善于細(xì)心觀察，開發(fā)自己的創(chuàng)新能力。
小題1:本題的選擇要注意上下文。四個選項均為動詞，語法上都可填入，但文章說的是影響我們的生活和工作話題，即這些發(fā)明的東西改變了我們的生活方式，故選B.
小題2:本題四個選項均為副詞，但根據(jù)上下文可知：新發(fā)明是為了解決問題，使得做事情更容易，所以A符合語境。
小題3:本段開始敘述H.L.Lipman的發(fā)明，講述他是如何有這個注意的H.L.Lipman，的發(fā)明是觀察中思考所得，而不是先有目標(biāo)，故不能選B.
小題4:從語法上看，本題四個選項均可做連詞用，但從語義上來說這里是承接關(guān)系，必須用and來連接三個賓語:pencil, paper, eraser故選B.
小題5:從上下文可知，寫作時他需要修改。
小題6:這樣他就經(jīng)常需要在書本下把橡皮找出來。本題同時考詞義辨析，四個選項都與“看有關(guān)，但只有表示“找出，找到�！�
小題7:“我想讓橡皮固定在一個地方（place）（便于尋找）”這是H.L.Lipman的想法。
小題8:這個地方當(dāng)然是在筆頭上最方便了，所以H.L.Lipman在鉛筆的一端刻出(cut)一個凹槽了
小題9:他考慮到別人也需要這種鉛筆，就把自己的設(shè)計（design）出售了。
小題10:（因為他的設(shè)計被出售）很快這種帶橡皮頭的鉛筆就普及。
