专题05 现在进行时-2025年新八年级暑假衔接复习&预习精品讲义（重点语法知识精讲+重难点题型突破）

【暑假衔接】语法知识及重难点题型突破大闯关（人教版） 专题05 现在进行时 一、现在进行时的定义 现在进行时主要用于表示目前正在进行的动作，有时也可表示现阶段在进行的动作。 The teacher is giving us an English lesson. 老师正在给我们上英语课。 The farmers are getting in their crops. 农民们正在收割庄稼。 We are making preparations for the conference. 我们一直在为会议作准备。 二、现在进行时的构成 现在进行时由＂be+现在分词（v-ing）＂构成。be应为助动词，一定不要漏掉！它应与主语的人称和数保持一致，即：I am/he/she/it 包括单数名词和不可数名词用is，you/we/they 包括复数名词用are。 1. 现在分词变化规则如下： a. 动词后直接+- ing（例：sleep+-ing→sleeping） b. 去掉不发音的e+-ing（例：bite-e+-ing→biting） c. 重读闭音节，且末尾只有1个辅音字母，双写辅音字母+-ing（例：sitting，beginning，getting，putting，running，stopping，cutting） d. 特殊变化：die→dying，lie→lying，tie→tying 2. 句式构成如下： 句式 句式结构 例句 肯定句式 主语+be（am，is，are）+现在分词+其他。 They are having an English class. 他们在上英语课。 否定句式 主语+be（am，is，are）+not +现在分词+其他。 They aren’t having an English class. 他们不在上英语课。 一般疑问句 Be（am，is，are）+主语+现在分词+其他？ Are they having an English class? 他们在上英语课吗? 特殊疑问句 疑问词+be（am，is，are）+主语+现在分词+其他？ What are you doing now? 你现在在做什么？ 助动词变化口诀：变疑问，往前提，句后问号莫丢弃；变否定，更容易，be后not 莫忘记。 三、现在进行时的应用 A表示现在（ 指说话人说话时）正在发生的事情。 We are waiting for you. B. 习惯进行：表示长期的或重复性的动作，说话时动作未必正在进行。 Mr. Green is writing another novel.（说话时并未在写，只处于写作的状态。） She is learning piano under Mr. Smith. C. 已经确定或安排好的将来活动。 I’m leaving for a trek in Nepal next week.（已经安排了） We’re flying to Paris tomorrow.（票已经拿到了） 在实际运用时，现在进行时常用以下几种情况： （1）当句子中有now时，常表示动作正在进行，这时要用现在进行时。 They are playing basketball now. 现在他们正在打篮球。 （2）以look，listen开头的句子，提示我们动作正进行，这时要用现在进行时。 Listen! She is singing an English song. 听，她正在唱英语歌。 （3）表示当前一段时间或现阶段正在进行的动作，且此时有this week，these days等时间状语，这时常用现在进行时。 We are making model planes these days. 这些天我们在做飞机模型。 （4）描述图片中的人物的动作，也为了表达更生动。此时也常用现在进行时。 Look at the picture. The children are flying kites in the park. 看这幅图，那些孩子正在公园放风筝。 四、现在进行时与一般现在时的区别 (1) 现在进行时强调目前正在进行的动作，而一般现在时强调经常性或习惯性的动作。如： I’m reading a story now. 我在看一个故事。(目前正在干的事情) I read stories in my spare time. 我有空时看故事。(经常性的行为) (2) 现在进行时强调现阶段一直在进行的动作，而一般现在时只表动作的重复，而不表示动作的持续。 What are you doing these days? 这几天你在干什么？ They are learning English in the summer holiday. 他们暑假在学英语。 They read English every day. 他们每天读英语。 They play volleyball every Sunday. 他们每周星期天都打排球。 (3) 表示短促动作的动词(如 jump, knock, beat, pick, skip等)的进行时，表示动作的重复。 The girls are jumping over there. 女孩子们在那边跳。 His heart is beating fast. 他的心脏跳得很快。 (5) 某些表示希望或想法的动词(如hope, wonder, want等)的进行时可以表示委婉客气。 I’m wondering whether you can help us now. 我不知道你现在能否给我们帮一个忙。 I’m hoping that you will succeed. 我正在希望你成功呢。 四类动词不用进行时 英语中有四类动词一般不用进行时(不用现在进行时和过去进行时) 1. 表心理状态、情感的动词，如love, hate, like, care, respect, please, prefer, know等，若用进行时则词义改变。 2. 表存在、状态的动词，如appear, exist, lie, remain, stand, seem等 3. 表感觉的动词，如see, hear, feel, smell, sound, taste等 4. 表一时性的动词，如accept, allow, admit, decide, end, refuse, permit, promise等。 五、现在进行时的特殊用法 1. 现在进行时表暂时 现在进行时可用来表示不会长期发生的动作或情况，或被认为在短期内正在进行的动作或存在的状况。 —What’s your daughter doing these days? 你女儿现在在干什么? —She’s studying English at Durham University. 她在达勒姆大学学习英语。 这种情况不一定在说话时发生： Don’t take that ladder away. Your father’s using it . 别把梯子拿走，你父亲在用呢。(即不一定现在在用。) She’s at her best when she’s making big decisions. 当做出最大决定时，她处于最佳状态。 暂时发生的事情也可以是在说话时正在进行着： The river is flowing very fast after last night’s rain. 昨夜下过雨后，河水流速很快。 现在进行时也用来表示当前的动向： People are becoming less tolerant of smoking these days. 如今人们对吸烟较为难以忍受了。 2. 现在进行时表将来 意为：意图、打算、安排、常用于人。常用词为come, go, start, arrive, leave, stay等。 I’m leaving tomorrow.

It is becoming popular to keep pets. Many people even hope to talk with their pets in everyday life. This was difficult before, but scientists are now using AI to help make this dream come true. Karen Bakker, a teacher in Canada, thinks that AI will make people closer to the world of animals and plants in the future. “AI helps people talk with bats and bees (蝙蝠和蜜蜂),” Bakker says. How does it work? When bats talk with one another, people first use AI to write down their sounds. Then they input the sounds into a computer. At last, they use AI to find out what the bats say. People cannot hear these sounds with their ears. But AI knows these sounds. It can also help people speak back to bats. People also find an interesting thing: when baby bats learn to “speak”, mother bats often lower their voices. However, as mothers, women often raise their voices during this time. As for bees, people use a computer to watch them and study their language. Scientists now know how bees send some information to talk.

People may not know that wind and rain can move garbage 67 land to sea. Sometimes, rubbish left on the ground gets blown away by strong wind. When it rains heavily, the water carries the garbage into rivers and seas. Plastic pieces are 68 (danger) to the sea animals. When they see the plastic floating on the sea waves, they think it is food, some of them hurt 69 (them) and get very sick or even die while trying to swallow (吞下) the plastic. Moreover, plastic 70 (take) a very long time to decompose (分解). Even while it starts to break, it just turns into smaller pieces. It can remain in the oceans for hundreds of years 71 it is hard to be broken down. Scientist are still working hard on it to find solutions. One group, Washed Ashore, thought of a new idea 72 (tell) people about the problems in the oceans. First, they take the garbage from 73 beach. Then, they clean and sort it. 74 (final), they work with the plastic pieces to make huge works of art. They are mostly about sea creatures. So far, Washed Ashore has created more than seventy works of art. Some of them 75 (travel) in a show all over the world now. In one show, people learn how plastic fools fish and other sea animals. 参考答案 51．A 52．C 53．D 54．B 55．B 56．C 57．A 58．A 59．D 60．B 【导语】本文介绍了北京时间早上七点时，东京、巴黎、莫斯科、纽约、洛杉矶等不同地区的人们因时差而正在进行的不同活动，如起床、工作、睡觉、回家等。 51．句意：此刻，全世界的人们都在做着不同的事情。 At在某个时间点；On在具体日期/星期；To到；From从。“this moment”表示具体时间点，需用介词At搭配，at this moment表示“此刻”，符合语境。故选A。 52．句意：在北京，大多数人正在起床。 little很少，修饰不可数名词；few很少，修饰可数名词；most大多数；much许多，修饰不可数名词。“people”为可数名词复数，排除little和much；few表否定，与“早上人们起床”的语境不符；most表示“大多数”，符合常识。故选C。 53．句意：一些人在等他们的公交车或火车。 they主格，他们；them宾格，他们；theirs名词性物主代词，他们的；their形容词性物主代词，他们的。空格后“buses or trains”为名词，需用形容词性物主代词修饰；“their”符合语法。故选D。 54．句意：在巴黎，现在是午夜，所以人们现在不工作。 but但是；so所以；or或者；because因为。根据“it is twelve o’clock at night, ... people aren’t working now.”可知，前半句“午夜”是后半句“不工作”的结果，两者为因果关系；so表结果。故选B。 55．句意：有些人仍在安静地工作。 quiet安静的，形容词；quietly安静地，副词；lucky幸运的；luckily幸运地。“working”为动词，需用副词修饰；quietly符合语境，quiet/lucky为形容词，luckily语义不符。故选B。 56．句意：在莫斯科，现在是凌晨两点。 be动词原形；am与I搭配；is与he/she/it等单数搭配；are与we/you/they等搭配。主语“it”为第三人称单数，be动词用is。故选C。   57．句意：他们可以好好休息。 have动词原形，有/进行；has第三人称单数形式；having现在分词；to have不定式。“can”为情态动词，后接动词原形；have a good rest为固定短语。故选A。    58．句意：他们正玩得开心。 a不定冠词，泛指，用于辅音音素前；an不定冠词，泛指，用于元音音素前；the定冠词，特指；/零冠词。have a good time为固定短语，意为“玩得愉快”，需用不定冠词a。故选A。 59．句意：在洛杉矶，大多数人正在工作。 is working现在进行时，单数；work原形；works一般现在时第三人称单数；are working现在进行时，复数。根据上下文语境可知，此处需用现在进行时（am/is/are + doing）；主语“most people”为复数，be动词用are。故选D。 60．句意：有些人在拜访他们的一些朋友。 friend单数，朋友；friends复数，朋友；friend’s单数所有格，朋友的；friends’复数所有格，朋友们的。some of their + 可数名词复数表示“他们的一些……”，需用friends。故选B。 61．B 62．C 63．B 64．A 65．D 【导语】本文是一篇说明文，介绍了科学家利用人工智能帮助人们与动物交流的相关情况，包括技术流程、发现的动物交流特点等。 61．细节理解题。根据“Do you love to keep a pet at home?”可知，本文以提问的方式开启文本，故选B。 62．细节理解题。根据第三段“people first use AI to write down their sounds.

B. 习惯进行：表示长期的或重复性的动作，说话时动作未必正在进行。 Mr. Green is writing another novel.（说话时并未在写，只处于写作的状态。） She is learning piano under Mr. Smith. C. 已经确定或安排好的将来活动。 I’m leaving for a trek in Nepal next week.（已经安排了） We’re flying to Paris tomorrow.（票已经拿到了） 在实际运用时，现在进行时常用以下几种情况： （1）当句子中有now时，常表示动作正在进行，这时要用现在进行时。 They are playing basketball now. 现在他们正在打篮球。 （2）以look，listen开头的句子，提示我们动作正进行，这时要用现在进行时。 Listen! She is singing an English song. 听，她正在唱英语歌。 （3）表示当前一段时间或现阶段正在进行的动作，且此时有this week，these days等时间状语，这时常用现在进行时。 We are making model planes these days. 这些天我们在做飞机模型。 （4）描述图片中的人物的动作，也为了表达更生动。此时也常用现在进行时。 Look at the picture. The children are flying kites in the park. 看这幅图，那些孩子正在公园放风筝。 四、现在进行时与一般现在时的区别 (1) 现在进行时强调目前正在进行的动作，而一般现在时强调经常性或习惯性的动作。如： I’m reading a story now. 我在看一个故事。(目前正在干的事情) I read stories in my spare time. 我有空时看故事。(经常性的行为) (2) 现在进行时强调现阶段一直在进行的动作，而一般现在时只表动作的重复，而不表示动作的持续。 What are you doing these days? 这几天你在干什么？ They are learning English in the summer holiday. 他们暑假在学英语。 They read English every day. 他们每天读英语。 They play volleyball every Sunday. 他们每周星期天都打排球。 (3) 表示短促动作的动词(如 jump, knock, beat, pick, skip等)的进行时，表示动作的重复。 The girls are jumping over there. 女孩子们在那边跳。 His heart is beating fast. 他的心脏跳得很快。 (5) 某些表示希望或想法的动词(如hope, wonder, want等)的进行时可以表示委婉客气。 I’m wondering whether you can help us now. 我不知道你现在能否给我们帮一个忙。 I’m hoping that you will succeed. 我正在希望你成功呢。 四类动词不用进行时 英语中有四类动词一般不用进行时(不用现在进行时和过去进行时) 1. 表心理状态、情感的动词，如love, hate, like, care, respect, please, prefer, know等，若用进行时则词义改变。 2. 表存在、状态的动词，如appear, exist, lie, remain, stand, seem等 3. 表感觉的动词，如see, hear, feel, smell, sound, taste等 4. 表一时性的动词，如accept, allow, admit, decide, end, refuse, permit, promise等。 五、现在进行时的特殊用法 1. 现在进行时表暂时 现在进行时可用来表示不会长期发生的动作或情况，或被认为在短期内正在进行的动作或存在的状况。 —What’s your daughter doing these days? 你女儿现在在干什么? —She’s studying English at Durham University. 她在达勒姆大学学习英语。 这种情况不一定在说话时发生： Don’t take that ladder away. Your father’s using it . 别把梯子拿走，你父亲在用呢。(即不一定现在在用。) She’s at her best when she’s making big decisions. 当做出最大决定时，她处于最佳状态。 暂时发生的事情也可以是在说话时正在进行着： The river is flowing very fast after last night’s rain. 昨夜下过雨后，河水流速很快。 现在进行时也用来表示当前的动向： People are becoming less tolerant of smoking these days. 如今人们对吸烟较为难以忍受了。 2. 现在进行时表将来 意为：意图、打算、安排、常用于人。常用词为come, go, start, arrive, leave, stay等。 I’m leaving tomorrow.

It is becoming popular to keep pets. Many people even hope to talk with their pets in everyday life. This was difficult before, but scientists are now using AI to help make this dream come true. Karen Bakker, a teacher in Canada, thinks that AI will make people closer to the world of animals and plants in the future. “AI helps people talk with bats and bees (蝙蝠和蜜蜂),” Bakker says. How does it work? When bats talk with one another, people first use AI to write down their sounds. Then they input the sounds into a computer. At last, they use AI to find out what the bats say. People cannot hear these sounds with their ears. But AI knows these sounds. It can also help people speak back to bats. People also find an interesting thing: when baby bats learn to “speak”, mother bats often lower their voices. However, as mothers, women often raise their voices during this time. As for bees, people use a computer to watch them and study their language. Scientists now know how bees send some information to talk. They even make a robot bee and it can talk with other bees. 根据材料内容选择最佳答案。 61．How does the writer start the text? A．By giving an example. B．By asking a question. C．By telling a story.
