The three-month 1 900-mile journey from Paris to Warsaw is Dubanchet's 4 of raising awareness of food waste in Europe and throughout the world.As you can 5 the trip is no piece of cake.

Dr. Douglas feels that most people do not value themselves, but with love and self-respect anyone can be above normality and grasp success with the family, the office, or others.We have become too reliant on intelligence, beauty, and money for our own self -esteem. The loss of esteem reduces the will and ability to set and reach goals. In a series of reading Douglas teaches how to avoid negative statements, how to change them into self-facing behavior, and how to take charge of your mental attitude. Where other motivational and self-help work stops with the theoretical plan for success, Douglas takes everyday examples and puts them into his books. From raising children who believe in themselves t o using self-esteem to help bridge the gap in the workplace, he gives readers concrete solutions to the problems that might ruin their interpersonal relations.Self-esteem building comes from filling your thoughts with positive affirmations(肯定) and learning to react to failures with motivation instead of self-destruction. These lessons are valuable for anyone who feels that life is even slightly out of control. People who feel they have adequate esteem can learn to use it to make their success grander, faster, and more beneficial for others. Douglas approaches this process of self-development as a means of more than creating goodthings for the individual but also for setting up keys for influencing good things for others.For more than thirty years, Dr. Douglas has addressed more than two million people on topics from time management to spe aking effectively to raising drug-free children. He is the author of fifteen books, including How to Make a Habit of Succeeding. 5．What can we infer from Paragraph 1?A．Most people behave well enough.B．Self-respect means being above normality.C．Self-esteem matters much.D．Committing better equals greater success.6．Why does Douglas put everyday examples into his books?A．To be reliant o n self-esteem.B．To set and reach goals.C．To avoid negative thoughts.D．To offer concrete solutions.7．What does the author advise those whose life is slightly out of control to do?A．Learn to be positive.B．Face it unmotivatedly.C．Admit se lf-destruction.D．Ask for help.8．What’s the most important to be self-development?A．Influencing the individual.B．Influencing more people.C．Gaining more benefits.D．Speaking more effectively.Ⅱ.完形填空(2017·江西师⼤附中临川⼀中联考)For years I have had no idea what I have been doing with my life.I was a 30-year-old lawyer in New York.__1____being a lawyer was never my dream or goal in life.I honestly wanted to be a writer.I have a great __2____ and would write amazing stories in my head.But I always knew that being a writer was __3____ possible for me because it was a better__4____ decision to stay a lawyer.Recently，I couldn’t fall asleep__5____ my usual time of 10 p．m., and when I did fall asleep I had the same dream__6__.

2019年职称英语卫生类C级完型填空题目特点及解题技巧题目特点完形填空是职称英语考试的第六大题，共有15道小题，每题1分，总计15分。

完形填空部分的目的是要测试学生综合使用语言的水平，即理解篇章和使用词汇、语法的水平。

大纲规定本部分的考试时间为l5分钟，共设15题，每题1分，要求考生从每题给出的4个备选答案中选出一个答案。

备选答案能够是单词，也能够是短语。

完形填空从表面来看，就是要求考生把每个句子中删掉的词补全，而实际上，完形填空综合了词汇、结构、语法以及阅读理解部分的测试内容。

它不但测试考生在词汇和句子水平上使用语言的水平，还测试考生在篇章上综合使用语言结构的水平。

通过试题分析回顾，我们不难发现完形填空题以测试考生综合使用语言的水平为目的，这个水平具体体现在三个方面：①对词汇知识的掌握，②对语法结构知识的掌握，③对篇章阅读水平的掌握。

特别指出的是，职称英语考试中完形填空题目的文章往往选自当年的《职称英语等级考试用书》中的完形填空练习题目，但是会做一定水准的改编，如更换备选项等，所以在备考过程中要特别重视考试用书中的完形填空练习题，但是不能死记答案，而是要以理解短文篇章为主。

考点分析2016年职称英语卫生类C级完型填空题目特点及解题技巧从以上分析能够看出：1．完形填空题目的篇章均为说明文，有较强的逻辑性，有利于考生利用上下文的语境实行答题。

2．从完形填空的考点来看，重点考查的词汇，其中包含2道左右的词组／短语的考查。

词汇的考查都不是孤立的，而是对上下文语义线索的考查。

3．完形填空对语法的考查主要涉及各类从句(诸如定语从句、宾语从句等)的考查，所以考生在备考复习时，要注意从句部分的复习；偶尔会考查非谓语、时态和倒装结构等。

下面我们按照考点分布一一讲解。

考点一：词汇词汇是完形填空题考查的重点，在完形填空15道题目中较大比例的是对词汇的考查。

在完形填空题中，主要是考查考生对单词词义的准确把握，特别是近形词和近义词的考查，同时也注意常见的短语结构的考查。

2019年职称英语理工类A级完型填空练习题及答案1Earth's Inner CoreScientists have long struggled to understand what lies at the planet's center. Direct observation of its center is impossible, so researchers must （1） to other evidence.In 1889, a German scientist detected a severe earthquake in Japan. Geophysicists concluded that shock waves （2） jolts （晃动） from one side of Earth through the center to the other side. Then in 1936, Danish geophysicist Inge Lehmann studied the waves' （3） to determine that within Earth's core of molten （熔化了的） iron lies a solid inner core －but （4） that core was made of eluded （难倒） her. Other geophysicists quickly determined that Lehmann's inner core was composed mostly （5） iron. Since then, Lehmann's discovery has （6） conventional Earth science.But now scientists are challenging traditional theory with new and radical （7）. For example, Earth's center could actually contain an "inner core within the inner core," claim Ishii and colleague Adam Dziewonski.Analyzing hundreds of thousands of earthquake wave （8）, they maintain that the inner core has at its heart a tiny, even more solid sphere （球体）. This sphere "may be the oldest fossil （9） from the formation of Earth," says Dziewonski.Dziewonski and Ishii speculate that shortly （10） Earth formed around 4.8 billion years ago, a giant asteroid （小行星） smashed into the young planet and nearly melted it. But Earth's center didn't quite melt; it （11） mass as theplanet cooled. The core within a core may be the kernel （核心） that endured. "Its presence could change our basic ideas about the （12） of the planet," Dziewonski says.Dziewonski's idea is tame （温和的） compared to the （13）theories of independent geophysicist J.

Herndon has a truly revolutionary notion： Within the nickel silicide （硅化物） inner core is also an "inner" inner core － an 8 km-wide ball of theelement uranium. Uranium is radioactive. Herndon thinks the uranium releases heat energy as its atoms （15） fission-split and crash into one another in a chain reaction. Inother words, we may live on top of a gigantic, "natural" nuclear power plant.1 A try B leave C turn D point2 A create B receive C feel D overcome3 A work B solution C job D patterns4 A whether B what C why D how5 A from B within C of D to6 A followed B dominated C restored D opposed7 A ideas B demands C phenomena D movements8 A things B acts C methods D records9 A taken B benefited C left D kept10 A after B before C since D when11 A expanded B modified C gained D melted12 A size B origin C structure D shape13 A radical B traditional C classical D conventional14 A system B copy C model D compound15 A charge B last C experience D show参考答案：1.
