本句事实上是一个祈使句，表示教师关于学生做实验的要求。

故B正确。
【触类旁通】It wasn’t until nearly a month later I received the manager’s reply.〖答案〗D〖考点〗考查强调句的用法。

高考英语一轮复习语法专题词类复习2讲含解析新人教版选修820211212192
2021年高考英语一轮复习语法专题词类复习2讲含解析新人教版选修820211212192有提示词的词类复习：动词、非谓语动词、形容词和副词、名词、动词、非谓语动词在前面差不多复习过那个地点不在细讲基础知识。
名词（1）考纲要求名词应把握以下内容：分清名词的可数性与不可数性；可数名词有单复数，有些名词只有复数；物质名词、抽象名词不可数但能够具体量化使用；名词所有格和of格的语言现象；名词直截了当作定语；国家名词的正确使用；名词词义的区分和搭配；单位名词的搭配；名词前的修饰语so, as, quite等；time及常考点。
（2）命题规律名词的“可数”与“不可数”是高考命题的热点之一。
名词的考查强调语言的情形化，重点考查在特定语境、真实语境中的准确辨析、选择和运用名词的能力。
名词短语的固定搭配及名词作定语也是高考命题的注意点。
另外，在熟练把握名词的差不多意义和用法的同时，要专门留意某些名词的差不多意义之外的引申、拓展和熟词生义的用法。
2020年的高考将会连续保持稳固，命题形式会更加灵活、新颖。
试题类型一样是在单选选择题或完形填空中考查。
名词的考点归纳：(1)名词词义辨析: custom风俗适应，habit个人适应，tradition传统；scene场景，scenery自然风景（总称），view特定位置的景观，sight人文或历史景观；skill技能，ability能力，talent才华，strength 优势，长处等等(2)抽象名词具体化：beauty美、漂亮（不可数名词） a beauty美人、漂亮的东西（可数名词）；experience 体会（不可数名词）an experience一次经历（可数名词）；surprise吃惊、惊奇（不可数名词） a surprise 令人吃惊的人或事（可数名词）；honor荣誉、信誉（不可数名词） an honor一种光荣的人或事（可数名词）；failure失败（不可数名词） a failure/failures失败的人或事（可数名词）等等。
2021高考英语一轮统考复习第二部分高考重点语法突破专题二第1讲定语从句学案(含解析)新人教版
专题二 句法篇第1讲 定语从句考点一 定语从句概述及关系代词引导的定语从句一、定语从句概述1．定义：在复合句中，修饰限定某一名词(或代词)的句子，叫定语从句。
2．先行词：被定语从句修饰的词称为先行词。
先行词一般是名词或不定代词，如：some， any， every， no与body, thing 的合成词或all, none, any, some, that, those 等代词。
数词和人称代词也同样可作先行词。
3．关系词：连接先行词与从句的词叫关系词。
关系代词：who, whom, which, that, whose, as 等。
关系副词：when, where, why 等。
4．分类：定语从句分为限制性定语从句和非限制性定语从句两类。
区别：限制性定语从句对先行词起修饰限定作用，而非限制性定语从句对先行词起补充说明作用，先行词与定语从句往往由逗号隔开。
试比较：⎩⎪⎨⎪⎧ He has two sons ， who work in the same company.他有两个儿子，他们在同一公司上班。
他只有两个 儿子He has two sons who work in the same company.他有两个儿子在同一公司上班。
/他有两个在同一 公司上班的儿子。
可能不止有两个儿子5．功能：相当于形容词，修饰名词或代词，在句中作定语。
6．位置：定语从句常置于被修饰词之后；as 引导的非限制性定语从句可置于主句前、句中，也可置于主句之后。
①Those who are for the plan raise your hands, please.请支持这个计划的人举手。
②As is known to us all, the earth is spinning around the sun.我们都知道，地球围绕太阳旋转。
二、关系代词引导的定语从句引导定语从句的关系代词有：that, which, who, whom, whose, as等，关系代词可作主语、宾语、定语等。

高考英语二轮复习专题12特殊句式教学案含解析word版本
专题 12 特别句式从近几年高考试题来看，特别句式主要观察倒装句、省略句和重申句的用法。
命题的着要点在以下几个方面：1．观察倒装句式，特别注意以下三种状况：(1)含有否定意义的词置于句首时，部分倒装。
(2)only位于句首修饰状语等，部分倒装。
(3)so/such...that句型中，so/such位于句首时，后边的主句倒装，that从句不倒装。
2．观察省略句的构成，特别是以下四种状况：(1)省略主语、主语和谓语、主语和谓语的一部分。
(2)状语从句省略为“连词＋非谓语动词”形式，务必需明确句子主语与非谓语动词的逻辑关系以及非谓语动词与谓语的时间关系。
(3)不定式的省略。
(4)not，so，neither，nor的“代替性”省略。
3．观察重申句型的构成和重申谓语的方法。
近几年高考更加重视观察知识之间的交错现象，加大了综合观察语法知识的力度，以下几个方面要惹起高度重视：(1)重申句型的一般疑问句式和特别疑问句式的构成。
(2)重申 not...until...句型的特别构成方式。
(3)把重申句型与定语从句、省略句以及重申句型与时间状语从句、地点状语从句的观察等交融到一起观察学生综合掌握语法知识的能力。
一、倒装句( 一 ) 圆满倒装 (Full Inversion)谓语动词圆满放在主语从前的句子即是圆满倒装句。
这种句型主要有：1．表示方式、方向的副词或介词短语，如here, there, up, down, in, away, off,out, in the room, on the wall等，置于句首，且主语是名词时。
如：In a lecture hall of a university in England sits a professor.在英格兰一所大学的讲堂里坐着一位教授。
South of the river lies a small factory.一个小型工厂坐落在河的南岸。
Out rushed the children.孩子们冲了出去。

专题十二特殊句式1.(2018·全国卷Ⅱ，语法填空，改编)Diets have changed in China—and so too ________ its top crop.答案：has 该句是一个倒装句。
当前面的句子是肯定句时，用“so＋助动词/系动词/情态动词＋主语”表示“某人也……”。
该句中助动词的选用根据前面句子的谓语动词来判断。
2．(2018·全国卷Ⅱ，70)China's approach to protecting its environment while ________ (feed) its citizens “offers useful lessons for agriculture and food policymakers worldwide，” says the bank's Juergen Voegele.答案：feeding 此处是省略句。
状语从句主语为it，谓语动词含有be动词时，可以省略it和be。
由“连词＋doing”构成，表示主动的动作。
相当于while it is feeding its citizens ... 。
3．(2018·天津高考，5，改编)—I'm moving in a few days and I wonder if you could help.—You bet. Just let me know when, ________ I'll be there.答案：and 该句式是“祈使句＋and＋简单句”，祈使句相当于条件，简单句相当于主句。
4．(2018·天津高考，14)It was only when the car pulled up in front of our house ________ we saw Lily in the passenger seat.答案：that “It is/was ... that ...”是强调句型。
5．(2017·天津高考，11)It was when I got back to my apartment ________ I first came across my new neighbors.答案：that 本句中去掉It was 和空格所填词，句意完整，可以判断本句是强调句型，被强调的是时间状语从句when I got back to my apartment，故填that。
6．(2019·天津高考，12)The professor warned the students that on no account ________ use mobile phones in his class.答案：should they 此处表示否定含义的介词短语位于宾语从句句首，宾语从句要用部分倒装结构；情态动词should表示“理应，应该”，故填should they。
