【正文】 blished on the basis of Institute of Polymer Chemistry, Big Name University. After graduating in the summer of 2020, I felt that I needed to develop my experimental skills. I chose to work at a key state laboratory established at the Institute of Polymer Chemistry, Big Name University. In this project, I worked on the nanoparticles of polystyrene and successfully produced 20 nanometers particles. I worked on nanoparticles of polystyrene to successfully produce 20 nanometer particles. In pleting the project, I used (GC), fluorescence (FL) spectrum, (NMR), scanning electronic microscope (SEM), and dynamic light scattering to analyze the polymerization system quenched in different stages. I used GC, fluorescence spectrum, NMR, a scanning electron microscope and dynamic light scattering to analyze the polymerization system at different stages. The fluorescence spectrum showed some peculiar trends to which I applied detailed photophysical analysis. Finally, I discovered that phase separation exists in the monoproperty St/DVB polymer. I was devoted to my research which I found very enjoyable. Fortunately, it was fruitful – several international journals have published papers quoting our results. （ Editor39。 一篇比較合格的 PS，用我們現(xiàn)在通常所用的 A4 紙和五號(hào)字來(lái)衡量，大概一頁(yè)半就足夠了。 在我們往美國(guó)寄申請(qǐng)材料的時(shí)候，只要寄學(xué)位證書(shū)就行了，不用寄畢業(yè)證書(shū) 我國(guó)的申請(qǐng)者很少談到品格。 如何選擇寫(xiě)作素材 有了主題，內(nèi)容這些士兵就像有了戰(zhàn)斗的目標(biāo)，而你也就是戰(zhàn)斗的統(tǒng)帥。所謂 ―反思 ‖，就是要回顧自己的整個(gè)人生經(jīng)歷或者學(xué)習(xí)生涯，比如從小學(xué)、高中、大學(xué)直到現(xiàn)在（一般來(lái)說(shuō)， PS只要寫(xiě)出自己大學(xué)階段的經(jīng)歷就可以了），自己有哪些與眾不同之處。如果你的寫(xiě)作使他對(duì)你產(chǎn)生良好的印象，覺(jué)得你這個(gè)人并不討厭，語(yǔ)言能力不錯(cuò)，也沒(méi)有像其他人那樣，在寫(xiě)作時(shí)抄襲，他就可能喜歡你，決定把你要下來(lái)，因?yàn)樗耆羞@個(gè)決定權(quán)，這一點(diǎn)是常被中國(guó)學(xué)生所忽略的。比如說(shuō) ―我出生在 X 年 X 月 X 日 ‖，或者 ―我出生在四川重慶 ‖等等。 怎樣避免公式化寫(xiě)作 ? 不要引用名人名言 ? 不要強(qiáng)調(diào)自己專(zhuān)業(yè)的重要性 ? 不要介紹自己的生辰八字和誕生地 ? 不要強(qiáng)調(diào)自己的聰明 和勤奮 我國(guó)的申請(qǐng)者在 PS的寫(xiě)作中最常見(jiàn)或者說(shuō)最嚴(yán)重的問(wèn)題就是千篇一律的―公式化寫(xiě)作 ‖。 官方網(wǎng)站： 分?jǐn)?shù)重要，但不是想象的那么重要 獲得獎(jiǎng)學(xué)金與高分沒(méi)有那么緊密的聯(lián)系。 申請(qǐng)材料就像是申請(qǐng)者的一個(gè)替身，代替申請(qǐng)者本人在美國(guó)大學(xué)評(píng)審委員會(huì)的成員面前陳述申請(qǐng)者 曾經(jīng)取得過(guò)哪些成就 . ★ 北京大學(xué) ★ 英語(yǔ)系學(xué)生專(zhuān)用口語(yǔ)學(xué)習(xí)機(jī)：更適合 出國(guó)、工作、旅游 使用。 申請(qǐng)材料對(duì)于留學(xué)申請(qǐng)的成功幾乎能起到四兩撥千斤的作用。 第三個(gè)錯(cuò)誤是喜歡介紹自己具體的出生日期及出生地點(diǎn)。 了解你的閱讀對(duì)象 許多申請(qǐng)者對(duì)國(guó)外的教授如何閱讀他們的材料存在若干認(rèn)識(shí)上的誤區(qū)。 要想寫(xiě)出一篇好的、具有個(gè)性化的 PS 是有一定的方法的，在我看來(lái)，具體應(yīng)該分成如下幾個(gè)步驟： 第一步： Reflection （反思）。 目前我國(guó)很多申請(qǐng)者的寫(xiě)作常常是沒(méi)有主題。要寫(xiě)出對(duì)未來(lái)的展望、自己的經(jīng)驗(yàn)、領(lǐng)導(dǎo)能力、合作能力、創(chuàng)新能力、想像力等。 不好的 PS 的文 章都是千篇一律的，好的 PS 的文章卻各有各的風(fēng)格。s ment ： Sounds negative. Sounds that professors there don‘t care. The statement lacks credibility. ） Because of my excellent performance in chemistry and puter, I was elected to the Softchemi Society, a society that develops program for Computer Aided Instruction of Chemistry. I am the only students who holds the longest membership over 3 years and one of the two students who were admitted into this program exceptionally when we were only freshmen. (Due to my excellent record in chemistry and puter courses, I was one of only two freshmen to be elected to Softchemi Society, a society which develops programs for Computer Aided Instruction of Chemistry.) We worked in our spare time and developed a series of chemistry education software that are used in the teaching now. (We worked in our spare time to develop chemistry education software for advanced teaching in universities. I am proud to say that it is still in use today. 強(qiáng)調(diào) ) Our program named ―Periodic System of the Chemical Elements‖ was awarded the first prize by the state Educational Department of China. (The software we developed, entitled ―the Periodic Table of Chemical Elements‖, was awarded first prize by China‘s Education Ministry.) During the whole course of work, I improved my experiment operation and mastered many kinds of software. (Work on this program helped me improve my practical skills and master many kinds of software. or ―during the whole course, I kept improving.) At the same time, a strong interest in materials (material science. ) is established, when I read a lot on material chemistry to solve the problems in the development of the software. （ A strong interest in material chemistry research was established during the hours I spent poring over books in order to solve the software problems. ） At the autumn of 2020, Professor Xu made me a member of his research team, a key research team and laboratory in China. (In the fall of 2020, I was chosen to carry out research at one of China‘s key laboratories.) I was remended for doing my BS research under the direction of Professor Pan. The topic of my thesis is ― the Preparation of the Chisotan Microcarriers‖. It was a challenging topic because nobody in the college had ever tackled it.（ Editor39。 ） It is the area my strongest interest lies in. Initially kindled with the desire to look into the innermost nature of things, my interest in the microworld has been strengthened through years of study and research work. My interest in science initially began with a desire to look at the innermost nature of things. It is an interest which has bee stronger with years of study. （ Editor39。s ment：以下都是廢話。 but better: under any circumstances, discrimination based on race, cultural background and creed.)

Because if you think about it, the two things or elements are not really parallel. Even though I had to work to help my parents financially, through diligent study, I outperformed most of my classmates.) （ Editor‘s ment： This paragr
