① 急！！！！！！！生活中的小發明 翻譯成英文~~~
Reader usually places the bookmarker (often a piece of rectangular paper or cloth) in the page he is reading before close the book, which will help him to find the page quickly and accurately when he continues the reading. Whereas this kind of bookmarker only help in remembering the page but not exact paragraph he finished last time and the reader therefore has to find himself. However, the precise bookmarker we have can mark the last paragraph he finished. The precise bookmarker is made of plastic with shape of rectangle. There is splint with a incision of U shape on the top of the bookmaker which can be used to fasten the itself on the page. A mobile plastic marker, having two horizontal cut lines, is in the bookmarker and the main body of the bookmark passes through by a way of knitting. Thus the marker can move freely down and up. The terminals of the two horizontal cuts can be bent and increase the friction force to fix the marker in right place. When read to a certain paragraph, put the book marker on the top of the page and move the marker to the paragraph being read and close the book. When you open the book next time, you can find the exact paragraph you want to continue.

小發明，大貢獻——圓珠筆的故事
Not many people have given their names to the English language. Among those who have is Laszlo Josef Biro. He was the maker of the first 「Biro」, a name still used around the world for his most successful invention（發明）, the ballpoint pen.
Biro patented（申請專利） his first pen in 1938. It had a tiny ball bearing in the tip which picked up ink as it turned against the paper. During the Second World War, Biro went to Argentina（阿根廷） where he had some success selling his proct.
However, he never took a patent in the United States. Partly because of this, American companies such as Bic, Parker, and Papermate have dominated（支配、統治） the writing market ever since the ballpoint pen became popular in the 1950s.

④ 小發明 PPT 飛
一天，魏強同學跟爸爸到一個朋友家做客，一進門就把他給難住了：主人家鋪內著地毯，不換鞋顯得不禮容貌。換鞋吧，腳又有臭味。回家後，魏強就想：如果有一種拖鞋，不用脫下腳上的鞋就能穿，那該多好！後來，他從旅遊鞋上的尼龍搭扣得到啟發：將拖鞋上的鞋袢裝上尼龍搭扣，一按就搭上，一掀就拉開，要肥要瘦不就可以調節了嗎？於是他找來一雙舊拖鞋，剪開鞋袢，縫上尼龍搭扣，做成了"好客鞋"。這項小發明在第四屆全國青少年發明創造比賽中獲得了三等獎。
其實，魏強的小發明只不過是將尼龍搭扣這項別人的發明移植到拖鞋上，但使拖鞋有了新的功能，尼龍搭扣也有了新用途，這項小發明也就具備了新穎性。

⑦ 有沒有描寫進行小發明的英文文章
摘 要：1、利用學校的生物園地，通過配製合理的營養液，完全可以進行草莓的無土栽培。
2、無土栽培的草莓具有生長速度快、長勢好、花芽分化 早、開花結果早、產量高的特點。
關鍵詞：培養基、營養液、無土栽培、簡單易行
將作物栽培在除土壤以外的培養基上，叫無土栽培。無土栽培具有不佔地或少佔地、換茬快、環境清潔、產品無污染和生長好、品質優、色鮮味美等優點，為花卉蔬菜、糧食以及水果生產的工業化、自動化開辟了廣闊的前景。 一、實踐目的 通過對草莓的無土栽培實踐活動，使我們初步掌握無土栽培的技術，懂得利用水培法來確定植物必須礦質元素的原理和礦質元素對植物的生理作用，同時也培養了同學們的學習興趣和實踐能力。 二、實踐原理 植物根從土壤溶液中吸收水分和無機鹽，土壤顆粒主要起著固著作用。根據這一原理，將植物生活所需的無機鹽按一定比例配成營養液進行作物的無土栽培。 三、實踐方法 採用與泥土盆栽草莓相對照試驗，盆栽草莓使用一般的菜園土作固著物，施用化肥和農家肥，進行水肥管理。 四、實踐器材 無土花盆（雙層塑料套盆或採用罐頭瓶、硬泡沫塑料做定植板也行）、草莓苗、營養液原液、天平、洗凈的碎石或蛭石、溫度計等。 五、 試驗與管理 1、試驗時間：2007年9月－2006年5月；2007年9月－2006年5月 2、試驗地址：校生物園 3、營養液原液：經試驗得知，表1為最佳配方。 4、栽培方法：選擇無病蟲害、植株矮壯、具4－5片葉、頂芽飽滿的壯苗，洗凈根上泥土後，定植在無土花盆的上盆中，用碎石子或蛭石作固著物，下盆中盛清水，待長出新根後（1周左右）將清水倒掉，換上培養液。 表1 無土栽培草莓營養液原液配方 成分名稱 含量（MG/L） 硝酸鈣 236 硝酸鉀 303 磷酸銨 57 硫酸鎂 123 三氯化鐵 500 硼 酸 1.2 氯化錳 0.72 5、管理： （1）及時添加營養液。每周補液1－2次。每次50－100ml。進入4月份以後，氣溫升高、蒸發快，同時正當開花、結果盛期，需肥量大，每2－3天補液1次，並要增加營養液的濃度。一般開花前培養液濃度是 原液∶水＝1∶9 開花後培養液濃度為 原液∶水＝1.7∶8.3 （2）隔天上午噴水1次，4月開始每天噴水1次，保持相對濕度70－80％。 （3）光照為生物園里的自然光照（注意不要放在直射太陽光下，以免培養液溫度升得過高造成根壞死）。 （4）注意及時摘除老葉、匍匐莖。當發現植株下部的葉片呈水平著生，開始發黃、葉柄基部也開始變色時，應立即摘除。匍匐莖消耗養分大，為保證果大質優，發現生在葉片基部的幼嫩線狀物--匍匐莖，要及時摘除。 （5）注意病蟲害防治。草莓蟲害主要有蚜蟲和紅蜘蛛，可用內吸殺蟲劑防治，如甲胺磷、樂果等。病害主要有灰霉病、病毒病等，可用波爾多液、托布津等殺菌劑防治。 （6）注意及時疏蕾墊果。 六、觀察記錄情況 1、根系在2℃時開始活動，在7℃時開始長新根，最適生長溫度為15－20℃，高於30℃時停止生長，並有根部變色受害情況，在－8℃時根系受到凍害。 2、地上莖、葉氣溫在5℃時開始生長，生長最適氣溫為15－25℃氣溫過高過低生長都較緩慢，氣溫高於30℃以上有老葉焦邊現象。 3、氣溫在5℃以上開始花芽分化，花芽分化最適氣溫在5－15℃之間，開花在10℃以上，開花盛期在15℃左右。 4、培養液pH值在6.5-7最為適宜。 5、開花結果情況見下表 表2 無土栽培草莓開花結果記錄統計表 盆數 盆栽時間 第一花序 第二花序 總果實／株 月／日 葉片數 開花 月／日 小花朵數 果實成熟月／日 開花月／日 小花朵數 果實成熟月／日 數量 重（克）七、結果與體會 1、無土栽培的草莓比盆栽草莓生長速度快、長勢好、花芽分化早、開花結果早，從定植到第一花序開花和果實成熟都比盆栽提前一周左右，並極少有病蟲害。 2、試驗證明，室內無土栽培草莓方法簡單易行，成本較低，在家庭中推廣種植可充分利用室內空間，既可以觀賞、美化環境，又能品嘗到氣味芳香、營養豐富的春季水果珍品，是一舉多得的好事，深受群眾歡迎。通過實踐，既幫助我們理解了教材，又培養了學習興趣和實踐能力，並促進了無土栽培技術在本地的推廣。
