语法填空之动词时态
2023上海秋考
Once upn a time , in the heart f Africa, there was a king wh (2l) __________( knw )fr his wisdm and curage, His name was Msi, meaning "smke" in his native tngue.
【答案】21.was knwn
【详解】
21.was knwn【解析】考查被动语态。分析句子结构，此句为there be句型，主句谓语动词是 was。 curage为wh引导的定语从句，空格处为从句的谓语动词，此处意为!“被人们所知道”，be knwn fr意为“因……而出名”，而且主句中的谓语为一般过去时,所以应该填 was knwn。
2023上海春考
As the name(26)__________ (imply), Advisers are there t advise: they d nt run the cmpanies.
Nrmally, three Advisers-ne n accuntancy, ne n prductin and ne n marketing,(27)__________ ( be ) available t each cmpany. Yung Enterprise makes it a rule that the Advisers must cme frm a variety f business ccupatins.
【答案】26. implies 27. are/will be/have been
【解析】
26. implies 考查一般现在时。根据句子结构和语境，这里用一般现在时的第三人称单数形式"implies"，表示"意味着"。根据原文句子结构和语境判断。
27. are/will be/have been 考查时态。根据句子结构，主语three Advisers后面的破折号是解释说明，判定空格处动词be是句子的谓语部分，再结合句意可知此处为主系表结构，而且“be available t”表示“可用于……，……可利用或得到的”，Advisers是复数，故填入are/will be/ have been。句意：通常，每家公司都有三名顾问，一名会计顾问、一名生产顾问和一名营销顾问。

Answer: An individual wh establishes and expands their wn cmpany thrugh innvative strategies(23)______(knw) as an entrepreneur During the expansin f their cmpanies, entrepreneurs are respnsible fr several imprtant tasks in additin t cash generatin. An entrepreneur perceives a cmmercial need in their sciety, (24) ________ (develp)an idea fr a business, and then takes the initiative t start their firm
【答案】 23 is knwn 24 develps
【解析】
23.is knwn
【解析】考查一般现在时的被动。结合问题"Hw Wuld Yu Describe An Entrepreneur?(你如何描述企业家?)"可知这个回答是在为企业家下定义，此处应为固定搭配“be knwn as”(被称为:被认为是...)，根据“An individual"可知此处的be动词是单数的，文章的时态为一般现在时，而且根据句子主语 individual后的 wh 引导的定语从句，空格处的动词为谓语动词。故填入 is knwn。句意:通过创新战略建立并扩大自己公司的人被称为企业家。
24.develps
【解析】考查一般现在时。此句的主语是 An entrepreneur，该空是一个谓语动词,且与前面的 perceives 并列，时态还是一般现在时，故填入 develps。句意:企业家在他们的社会中发现了商业需求，发展出了一个商业想法，然后主动创办了自己的公司。此空的陷阴主谱后面的空格处动词，惯性思维理解为非谓语结构。实际这个句子看完才发现是并列谓语结构。此题的失分较多，很多同学们会填写 develping:事实上是 develps。
