北师大版七年级下册Unit 1单元语法知识梳理与练习
一：单元语法知识梳理 (Unit 1 Every Day)
一、频度副词 (Adverbs of frequency)
【规则变化】 频度副词用于表达事件或动作发生的频率，通常用于回答 how often 提出的问题。常见的频度副词按照频度从高到低可以排列为：
always (总是, 100%) > usually (通常, 80%) > often (经常, 60%) > sometimes (有时, 40%) > seldom (不常/很少, 10%) > never (从不, 0%)。
【注意】 频度副词在句中的位置规律：“行前 be后”（即放在实义动词之前，be 动词、助动词或情态动词之后）。有时为了强调，sometimes 也可以放在句首或句末。
【例句】 Wang Chun always has lunch at school. 王春总是在学校吃午饭。 (在实义动词 has 之前)
They are always late for football practice. 他们足球训练总是迟到。 (在 be 动词 are 之后)
Sometimes I go swimming with my dad. 有时我和爸爸去游泳。
二、一般现在时 (Present simple) 的用法
【规则变化】
1. 一般现在时常用于表达持久的状态、重复的动作或日常习惯。
2. 一般现在时还可以用来表达普遍的真理或客观事实。
一般现在时通常使用动词的原形，但当主语为第三人称单数（如 he, she, it, 单个人名等）时，动词需要进行词尾变化。
【时间标志词】 一般现在时可以与下列表示时间的短语或频度副词连用：every day / week / month / year, always, usually, often, sometimes, seldom, never 等。
【例句】 Mr Chen works as a teacher. 陈先生是一名教师。 (持久的状态)
He never gets up late. 他从不晚起。 (日常习惯)
The Moon moves around the Earth. 月球绕着地球转。 (普遍的真理)
三、动词第三人称单数变化规则及句型转换
【规则变化】当主语是第三人称单数时，动词变化规则如下：
1. 一般情况：直接在词尾加 -s。如：live → lives, rain → rains。
2. 以 -s, -x, -ch, -sh, -o 结尾的动词：在词尾加 -es。如：kiss → kisses, watch → watches, wash → washes, go → goes, do → does。
3. 以“辅音字母 + y”结尾的动词：变 y 为 i，再加 -es。如：try → tries, study → studies。
4. 不规则变化：have → has。
【易错点：句型转换】
否定句：主语 + don't / doesn't + 动词原形。 (第三人称单数用 doesn't，其余用 don't)。
一般疑问句：Do / Does + 主语 + 动词原形？ (第三人称单数用 Does，其余用 Do)。
注意：无论是变为否定句还是疑问句，借助了助动词 don't/doesn't/Do/Does 之后，后面的谓语动词必须还原为原形！
【例句】 肯定句： She goes to work by bike. 她骑自行车上班。
否定句： She doesn't go to work by bike. 她不骑自行车上班。
疑问句： Does she go to work by bike 她骑自行车上班吗？
— Yes, she does. / No, she doesn't.

【参考答案与解析】
I. 单项选择
1.【答案】C
【解析】句意：我下午很少看电视，因为我有太多的作业。考查频度副词。always总是；usually通常；seldom很少，不常；often经常。根据“I have too much homework”可知，作业太多所以“很少”看电视。故选C。
2.【答案】B
【解析】句意：他足球训练从不迟到。他是一名非常积极的队员。考查频度副词的位置及词义。频度副词应放在be动词之后，即“is never”。根据后句“积极的队员”可知是“从不(never)”迟到。故选B。
3.【答案】B
【解析】句意：——Henry每天早上6点起床吗？——不。他早上6点半起床。考查一般现在时一般疑问句及单三形式。主语Henry是第三人称单数，疑问句借助于助动词Does，其后动词还原为get；答语中主语he也是单三，谓语动词用单三形式gets。故选B。
4.【答案】C
【解析】句意：Peter在我们学校教数学。我们都喜欢他的课。考查动词的第三人称单数形式。主语Peter是第三人称单数，谓语动词teach以-ch结尾，变单三需加-es，即teaches。故选C。
5.【答案】D
【解析】句意：地球绕着太阳转。这是一个普遍的真理。考查一般现在时表示客观真理。客观真理必须用一般现在时。主语The Earth是单数，谓语动词用单三形式moves。故选D。
6.【答案】A
【解析】句意：我哥哥不坐公交车去上班。他通常自己开车。考查一般现在时的否定句及单三形式。主语My brother是单三，否定借助于doesn't，后接动词原形go；后一句主语He是单三，动词drive变为drives。故选A。
7.【答案】C
【解析】句意：——你多久和朋友打一次篮球？——有时。考查特殊疑问词。根据答语“Sometimes(有时)”可知，问句询问的是频率。询问频率用How often。故选C。
8.【答案】B
【解析】句意：Jane每天早上遛狗。她不去跑步。考查动词单三及否定式。主语Jane和She都是第三人称单数，第一空用单三形式walks；第二空用否定doesn't后接动词原形go。故选B。
9.【答案】C
【解析】句意：我早上6点半洗脸刷牙。考查一般现在时。主语是第一人称I，谓语动词直接用原形wash。故选C。
10.【答案】C
【解析】句意：他晚上做作业，而且他经常很早睡觉。考查一般现在时单三形式。前后两句的主语He都是第三人称单数，所以动词do和go都要加-es变为does和goes。故选C。

一：单元语法知识梳理 (Unit 2 Food and Health)
一、句子结构 (Sentence structure): SV 与 SVO
【规则变化】 英语句子的基本结构通常包含主语 (Subject)和谓语动词 (Predicate verb)。根据谓语动词的性质，常见的简单句基本句型有：
1. 主语 + 谓语 (SV结构)：此处的谓语动词是不及物动词，后面不需要接宾语即可表达完整意思。
2. 主语 + 谓语 + 宾语 (SVO结构)：此处的谓语动词是及物动词，其后必须跟宾语（动作的承受者）才能使句意完整。
【注意】 句子的主语通常是名词或代词；宾语用于表述被施动的人或事物，也可以是名词或代词的宾格。
【例句】 SV结构： Emma (主语) runs (谓语动词). 艾玛跑步。
SV结构： I (主语) live (谓语动词) in London. 我住在伦敦。
SVO结构： Jack (主语) reads (谓语动词) books (宾语). 杰克读书。
SVO结构： I (主语) make (谓语动词) my own lunch (宾语). 我自己做午餐。
二、可数名词和不可数名词 (Countable and uncountable nouns)
【规则变化】
1. 可数名词：通常是具体的名词，可以被计数，有单数和复数形式。如：a book (一本书) → three books (三本书)；an apple (一个苹果) → two apples (两个苹果)。
2. 不可数名词：通常为不可以被计数的名词，没有复数形式。本单元常见食物和饮料类不可数名词有：oil (油), fruit (水果), cheese (奶酪), meat (肉), milk (牛奶), tea (茶), water (水), juice (果汁)。
【易错点：修饰词的区别】
只修饰可数名词： many (许多), a few (几个，表肯定), few (几乎没有，表否定)。
只修饰不可数名词： much (许多), a little (一点，表肯定), little (几乎没有，表否定)。
两者皆可修饰： a lot of / lots of (许多), plenty of (大量的), some (一些，用于肯定句), any (一些，用于否定/疑问句)。
【拓展】 在不可数名词前不能使用 a、an 或具体的数字。如果想表达不可数名词的数量，可以用“数词 + 表示量的名词 + of”表达。如：two bowls of rice (两碗米饭)、five glasses of water (五杯水)。有些名词既可以是可数名词，也可以是不可数名词，如：I'd love a coffee. (= a cup of coffee)
三、It is (not) + adj. + to do 句型
【规则变化】
该句型常用来表达说话人对某件事的看法、观点或评价。
1. 肯定形式： It is + adj. + to do (做某事是……的)。
2. 否定形式： It is not (isn't) + adj. + to do (做某事不是……的)。
【注意】 在这个结构中，It 是形式主语（无实际意义），真正的句子主语是后面的不定式短语 to do 部分。
【例句】 It is important to get enough sleep. 获得充足的睡眠是很重要的。
It is good to exercise every day. 每天锻炼是很好的。
It isn't healthy to go to bed late. 晚睡是不健康的。
It is unhealthy to drink lots of cola. 喝很多可乐是不健康的。

2.【答案】A
【解析】考查交际用语。在餐厅点餐时，服务员常问 "Can I take your order "（您现在点餐吗？），这是本单元重点交际句型。故选A。
3.【答案】B
【解析】考查代词用法。orange juice 是不可数名词，排除C(a few)和D(many，修饰可数名词复数)。句子是 "haven't got" 否定句，在否定句中通常用 any 表示“一些/任何”，而不用 some。故选B。

一：单元语法知识梳理 (Unit 2 Food and Health)
一、句子结构 (Sentence structure): SV 与 SVO
【规则变化】 英语句子的基本结构通常包含主语 (Subject)和谓语动词 (Predicate verb)。根据谓语动词的性质，常见的简单句基本句型有：
1. 主语 + 谓语 (SV结构)：此处的谓语动词是不及物动词，后面不需要接宾语即可表达完整意思。
2. 主语 + 谓语 + 宾语 (SVO结构)：此处的谓语动词是及物动词，其后必须跟宾语（动作的承受者）才能使句意完整。
【注意】 句子的主语通常是名词或代词；宾语用于表述被施动的人或事物，也可以是名词或代词的宾格。
【例句】 SV结构： Emma (主语) runs (谓语动词). 艾玛跑步。
SV结构： I (主语) live (谓语动词) in London. 我住在伦敦。
SVO结构： Jack (主语) reads (谓语动词) books (宾语). 杰克读书。
SVO结构： I (主语) make (谓语动词) my own lunch (宾语). 我自己做午餐。
二、可数名词和不可数名词 (Countable and uncountable nouns)
【规则变化】
1. 可数名词：通常是具体的名词，可以被计数，有单数和复数形式。如：a book (一本书) → three books (三本书)；an apple (一个苹果) → two apples (两个苹果)。
2. 不可数名词：通常为不可以被计数的名词，没有复数形式。本单元常见食物和饮料类不可数名词有：oil (油), fruit (水果), cheese (奶酪), meat (肉), milk (牛奶), tea (茶), water (水), juice (果汁)。
【易错点：修饰词的区别】
只修饰可数名词： many (许多), a few (几个，表肯定), few (几乎没有，表否定)。
只修饰不可数名词： much (许多), a little (一点，表肯定), little (几乎没有，表否定)。
两者皆可修饰： a lot of / lots of (许多), plenty of (大量的), some (一些，用于肯定句), any (一些，用于否定/疑问句)。
【拓展】 在不可数名词前不能使用 a、an 或具体的数字。如果想表达不可数名词的数量，可以用“数词 + 表示量的名词 + of”表达。如：two bowls of rice (两碗米饭)、five glasses of water (五杯水)。有些名词既可以是可数名词，也可以是不可数名词，如：I'd love a coffee. (= a cup of coffee)
三、It is (not) + adj. + to do 句型
【规则变化】
该句型常用来表达说话人对某件事的看法、观点或评价。
1. 肯定形式： It is + adj. + to do (做某事是……的)。
2. 否定形式： It is not (isn't) + adj. + to do (做某事不是……的)。
【注意】 在这个结构中，It 是形式主语（无实际意义），真正的句子主语是后面的不定式短语 to do 部分。
【例句】 It is important to get enough sleep. 获得充足的睡眠是很重要的。
It is good to exercise every day. 每天锻炼是很好的。
It isn't healthy to go to bed late. 晚睡是不健康的。
It is unhealthy to drink lots of cola. 喝很多可乐是不健康的。

一：单元语法知识梳理 (Unit 3 Rain or Shine)
一、现在进行时 (Present continuous) 的用法
【规则变化】
1. 现在进行时用于表达说话时正在进行的动作。
2. 现在进行时也可以用于表达已经安排好的不久的将来的计划。
构成形式：be (am / is / are) + 动词-ing。
【注意】
动词-ing 的变化规则：
一般在词尾直接加 -ing，如 look → looking, walk → walking；
以不发音的字母 e 结尾的动词，去掉 e 加 -ing，如 write → writing, make → making；
重读闭音节中，以一个元音字母加一个辅音字母结尾的动词，双写末尾辅音字母后加 -ing，如 swim → swimming, sit → sitting。
常见时间标志词：now、at the moment、at present、these days 等。
