创造发明每周一练

创造发明每周一练

怎样进行发明创造如果没有设想,人类的一切创造都不可能进行。

即使是最简单的小发明、小创造,最初也必须先要有一个设想。

在军事上,一个好的设想可能替代众多的军士而打胜仗;在企业管理上,一个好的设想(通常又称点子)亦可产生极大的经济效益甚至能拯救濒临倒闭的工厂。

用设想赚钱,本篇给你提供按“四步”就班的方法:第一步,一日一想。

即每天提出一个创造性设想。

创造性思维的结果叫做创造性设想,简称设想(idea)。

它可以是一个新思想、新工艺和新技术,也可以是一个新事物、新发明。

不管想出来的是怪的、奇的,还是不存在的、不可能实现的。

只要是“新颖”的,就是一个好设想。

第二步,每周一创。

即每周完成一项创造。

从本周一日一想中提出的六个设想中,选出一个最佳设想,并对这个设想进行改正、完善,形成初步的创造结果。

第三步,每月一发明。

即每月完成一项发明。

从本月四周中经过改正、完善的四个设想创造中,选出一个最佳创造,对其进行可行性分析和物化的研究,使它成为一个能在实践中采用的创造发明。

这时,你也可尝试与一些企业、个人接触,把这个创造发明卖给他们,获得报酬。

第四步,每学期一专利。

即每个学期申报一项国家专利。

从本学期经可行性分析和实践检验的多个发明创造中,选出一个最佳创造发明,进行市场调查,了解其经济效益和市场前景;然后做好有关专利文件上报国家知识产权局,以取得该创造发明的专利权。

有了发明创造,拿到了国家专利,按学习篇中提到的去做,推广自己的发明创造成果,使它转化成你的财富。

It will run from 8th July until 17th July. Applications close on 2nd June, 2008. For an application form, please download either the 2-page PDF or the word format document from the foot of the page. If you have any problems downloading the application form or any questions, please contact: London Summer School in Classics, King’s College London.Tel: 020 7848 2299Fax: 020 7848 2545OrganizationThe school is organized by the colleges of the University of London. The summer school offers eight days of intensive teaching in Greek and Latin. There are four language classes each day as well as lectures and a debate, between 10:30 am and 4:30 pm. The course is not residential (提供住宿的), and there is no teaching during the weekend of 12th to 13th July.The fee is £85.00. Travel grants (旅行补助金) are available as a contribution to your travel costs, but may not cover all your expenses. The travel grants are arranged during the summer school.Teaching is generally in groups of 12-15 people and it, as far as possible, comprises (包含) of students of roughly the same level of experience. The style of teaching is friendly, but demanding: a lot of work is expected from students during the school, but they usually find the whole experience both stimulating and valuable. Some classes concentrate chiefly on reading, while others offer a mixture of grammar and translation practice. Our tutors include some of the most experienced and talented teachers of Classics in the London area and beyond.The Summer School in Classics caters for a wide range of interests and for both school & university students as well as those who wish to learn Greek or Latin, or to revive their knowledge of the languages. Our principal concern is to provide a thorough program of language learning in a lively university environment.51.

While most people were warming up their cars, Trev or, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries(食品杂货),saving us from having to walk long distances from where we live.I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before. People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity(人性) as a whole. And it has influenced us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.56. How did people get to know the couple’s problem?A. From radio broadcasts.B. From TV newsC. From a newspaper.D. From a stranger.57.Which of the following is TRUE?A. The author used to get to work by bike.B. The author’s husband often parked the bike beside the back door.C. Several strangers offered bikes to them, but they only accepted oneof them.D. Somebody had stolen their bike before, but soon returned it to the author.58.What do we learn from the couple’s experience?A. Strangers are usually of little help.B. One should take care of their bike.C. News reports make people famous.D. An act of kindness can mean a lot.59. Why was the bike so important to the couple?A. They used it for work and daily life.B. It was their only possession.C. It was a nice Kona 18 speed.D. The man’s job was bike racing.60. We can conclude that _______A. the couple worked 60 hours a week.B. people were busy before ChristmasC. the stranger brought over the bikeD. life was hard for the young family.CThe literal meaning of philosophy is “love of wisdom”. But this meaning does not tell us very much. Unlike the other disciplines, philosophy cannot be defined by what you study, because it is actually unlimited. Anything can be the subject matter of philosophy: are, history, law, language, literature, mathematics, and in fact, the other academic disciplines are directly related to philosophy. For this reason you get a Doctorate(博士学位)of Philosophy (Ph. D. ) in biochemistry, or computer science, or psychologyTwo broad sub-fields of philosophy are logic and the history of philosophy. Logic is the science of argument and critical thinking. It provides sound methods for distinguishing good from bad reasoning. The history of philosophy involves the study of major philosophers and periods in the development of philosophy.Of what use is philosophy? First it is useful in educational advancement. It is necessary for understanding other disciplines. Only philosophy questions the nature of the concepts used in a discipline, and its relation to other disciplines. And through the study of philosophy, one develops sound methods of research and analysis that can be applied to any field.There are a number of general uses of philosophy. It strengthens one’s ability to solve problems, to communicate, to organize ideas and issues, to persuade, and to take what is the most important from a large quantity of data. These general uses are of great benefit in the career field, not necessarily for obtaining one’s first job after graduation, but for preparing for positions of responsibility, management andleadership later on. It is very short-sighted after all, to take a course of studies only for the purpose of getting one’s first job. The useful skills developed through the study of philosophy have significant long-term benefits in career advancement. No other discipline systematically follows the ideals of wisdom, leadership, and capacity to resolve human conflict61. What’s the meaning of philosophy according to the passage?A. social sciencesB. both social and natural sciencesC. natural sciencesD. the subject matter of politics62. What does “discipline” mean in the first paragraph?A. literatureB. scienceC. subjectD. occupation63. With the study of philosophy, you can .A. make progress in your career developmentB. succeed in everythingC. find a good job soon after graduationD. become a great leader64. According to the passage, which of the following statements is TRUE?A. Philosophy is an independent discipline.B. The study of philosophy brings you immediate benefits.C. Logic helps you to become a better thinker.D. The meaning of philosophy is too limited to define.65. From the passage, we can conclude .A. not all the subjects have to do with philosophyB. philosophy can be helpful for the study of any other subjectsC. a person will get a Ph.D. if he/she studies philosophyD. philosophy is the only solution to all the problems in the worldDWugging, or web use giving, describes the act of giving to charity at no cost to the user. By using , which is being added to a number of university computers across the UK, students can raise money every time they search, but it won’t cost t hem a penny.Research shows that students are extremely passionate about supporting charity — 88% of full time students have used the Internet to give to charity. This age group is often the least likely to have their own income. 19% of 22 to 24 year olds have short-term debts of more than £5,000. With rising personal debt levels in this age group, due to university tuition fees or personal loans and a lack of long-term savings, traditional methods of donating to charity are often not appealing (有感染力的) or possible.Beth Truman, a 21 year old recent university graduate, has used to donate to her chosen charity, the RSPCA, for two years and has seen the “wugging” movement grow in popularity with students. “When you’re at university you become more socially aware, but it’s sometimes hard to give to others when you have little money yourself,”says Beth. “Wugging is great for people in this age group as it allows them to use the technology on a daily basis to give to charity, without costing them a single penny.”Wugging is perfect for people who want to be more socially aware and supportive but don’t feel they have the means to do so. Students using the web can raise money for causes they care about without costing them anything in terms of time or money, and charities get a valuable source of funding. works like any other search engine, allowing users to search for information, news and images but users can decide which of the UK’s 170,000 charities they would like to support throug h their clicks. then makes monthly payments to every registered charity. Launched in June 2005, is now the eighth largest search engine and one of the busiest charity websites in the UK.66. What does “wugging”show According to the passage?A. a websiteB. a school organizationC. a student movementD.a charity-related action67. In the case of charity, ______.A. receives much money from studentsB. offers valuable information to studentsC. frees students of the financial worriesD. praises students for their money-raising 68. What does we think of the “wugging” movement?A. It makes popular in the UK.B. It becomes easy to do charity because of it.C. It results in students’ more social awareness.D. It helps students to save money.69. From the passage, we can inferred that ______.A. “wugging” is a win-win idea for both students and charitiesB. most full time students do charity on the Internet every dayC. helps students pay for the college educationD. is the most successful search engine in the UK70. What’s the general idea of this passage?A. “Wugging”, a new popular term on the Internet.B. More Britain charities benefit from the Internet.C. Students raise money for charity by “wugging”.D. British people show strong interest in charity.星期一(U1-M2)第一节单项填空1—5 DBBBA 6-10 DDCDC 11-15 CBCBA 16-20 ACDCC 21-25 CABAA第二节完形填空26-30 DBCAA 31-35 ACADB 36-40 BACDB第三节语法填空41. to 42. amazing 43. which 44. because 45. it 46. was selected47. like 48. room 49. decorated 50. to make第四节阅读理解51-55 DBBCB 56-60 CBDAD 61-65 BCACB 66-70 DCBAC。
