人教英语七下Unit5语法讲解及习题:现在进行时 第一部分 语法精讲 语法核心:现在进行时(Present Continuous Tense) 现在进行时是七年级下册核心时态,主要用于描述此时此刻正在发生的动作,或现阶段持续进行、当下未必正在做的动作,紧扣本单元“日常活动、场景见闻”话题,是单选、填空、句型转换、改错的必考重点。 一、句式结构(四大基础句型) 现在进行时统一公式:be动词(am/is/are) + 动词现在分词(v-ing),be动词随主语人称、数变化,动词必须用ing形式,二者缺一不可。 1. 肯定句 结构:主语 + am/is/are + v-ing + 其他 人称搭配:I用am;单数主语(he/she/it/单人名)用is;复数主语(we/you/they/复人名)用are 例句:She is reading a book now.(她现在正在看书) 2. 否定句 结构:主语 + am/is/are + not + v-ing + 其他 缩写:isn’t / aren’t(am无缩写) 例句:They aren’t playing basketball.(他们没在打篮球) 3. 一般疑问句 结构:Am/Is/Are + 主语 + v-ing + 其他? 作答规则:用什么be动词提问,就用什么回答,前后一致 例句:—Are you doing homework? —Yes, I am. / No, I’m not. 4. 特殊疑问句 结构:特殊疑问词(What/Where/Who) + am/is/are + 主语 + v-ing? 核心考点:对动作提问统一用What,地点提问用Where 例句:What is he doing?(他正在做什么?) 二、动词现在分词(v-ing)变形规则 所有现在进行时句子,动词必须严格变形,四大规则全覆盖: 1. 一般规则 绝大多数动词直接加-ing:look→looking、play→playing、talk→talking 2. 去e加ing 以不发音的字母e结尾,去掉e再加ing:write→writing、make→making、take→taking 3. 双写末尾辅音字母加ing(重难点) 满足重读闭音节、辅元辅结尾、末尾只有一个辅音字母三大条件,双写尾字母再加ing:run→running、swim→swimming、sit→sitting、shop→shopping 4. 特殊变形 以ie结尾的动词,变ie为y再加ing:lie→lying(躺)、tie→tying(系) 三、时态标志词(快速判题依据) 看到以下词汇,优先判定为现在进行时: 1. 时间类:now(现在)、right now(此刻)、at the moment(此刻) 2. 提示类:Look!(看!)、Listen!(听!)(句首提示当下动作正在发生) 四、高频易错点汇总 1. 绝对遗漏错误:进行时必须带be动词,不能直接单用v-ing; 2. 三单误区:现在进行时无动词三单变形,统一用ing形式; 3. 双写误区:非辅元辅结尾单词,禁止随意双写尾字母; 4. 问答误区:一般疑问句回答必须匹配be动词,不可混用do/does。 第二部分 专项练习题 题型一:单项选择 1.

B 解析:now提示现在进行时,主语you搭配be动词are,动词用watching。 3. B 解析:at the moment表此刻,主语为单数,用is playing。 4. C 解析:Listen! 提示动作正在进行,someone为单数不定代词,be动词用is。 5. C 解析:now提示进行时,主语they为复数,be动词用are,have变having。 6. B 解析:答句为正在做的动作,主语parents为复数,用are doing。 7. A 解析:根据后句语境,此刻正在写作业,主语I搭配am doing。 8. D 解析:现在进行时否定结构,be+not+doing,固定用doing。 9. C 解析:询问人物当下位置及动作,用现在进行时is swimming。 10. B 解析:right now为进行时标志,主语we为复数,be动词用are。 题型二:动词填空 1. are playing 解析:Look! 提示现在进行时,主语they为复数,be动词用are。 2. isn’t reading 解析:now提示时态,主语三单,否定式用isn’t+doing。 3. are; doing 解析:at the moment为标志词,主语you搭配are,动词用doing。 4. are having 解析:now提示进行时,students为复数,用are having。 5. are singing 解析:Listen! 提示当下动作,birds为复数,be动词用are。 6. is running 解析:now提示时态,主语三单,run双写n加ing。 7. are cleaning 解析:right now提示进行时,主语we用are,直接加ing。 8. is making 解析:主语she为三单,make去e加ing,整体为is making。 题型三:选词填空 1. am 解析:主语I固定搭配be动词am。 2. is 解析:单数主语father搭配is。 3. are 解析:复数主语children搭配are。 4.
