Unit 5 Section 3 For Better Performance and Around the World（PPT课件+Word版）-【创新教程】2025-2026学年中职英语拓展模块同步教案（外研版2021）

Section 3　Grammar in Use 动名词作主语、宾语 一、动名词作主语 1．表示一般行为，谓语动词用单数。 Collecting information is very important to a businessman. 对于一个商人来说，收集信息是非常重要的。 Staying up too late is bad for our health. 熬夜对我们的健康是有害的。 2．用it作形式主语，真正的主语是动名词，同学们需要记住下面这几个句型： It's no use/ good doing sth.； It's a waste of time doing sth.； It's so nice/foolish/interesting doing sth. It's so nice talking to you. 和你谈话很高兴。 It's no good smoking. You'd better give it up. 吸烟有害健康，你最好戒烟。 It's no use arguing with him. 和他争论是没有用的。 It's a waste of time waiting here. 在这里等是浪费时间的。 3．动名词和不定式作主语的区别： 不定式作主语，表示的是具体某一次的行为，用动名词作主语表示抽象或泛指的动作。通常两者可以相互转换，但是下面几种情况除外： (1)主语和表语要保持一致。也就是说，表语是动名词，主语也要用动名词，表语是不定式，主语也要用不定式。 Seeing is believing.还可以说成To see is to believe. (2)在句型It's no use/ no good doing；It's a waste of time doing等当中，通常用动名词。 It is a waste of time watching TV too much. 看太多电视是浪费时间的。 (3)但是在常用句型，It is＋adj.＋to do和It is＋adj.＋for/of sb.to do等当中，常用不定式。 It's necessary for us to learn English well. 学好英语对我们来说是很有必要的。 It's not difficult for you to finish the work on time. 对你来说按时完成这项工作不是很难。 二、动名词作宾语 1．一些动词后面通常接动名词作宾语： suggest，finish, admit，advise，avoid，can't help，consider，deny，enjoy，escape，excuse，leave off，mind等。 2．作介词的宾语 如最常用的一个例子，Thank you for helping me.谢谢你帮助我。 需要我们注意的是介词to的宾语。to既可以是介词，也可以是不定式符号，在学习中特别容易混淆。如果是介词，后面就接动名词；如果是动词不定式符号，后面就接原形。 针对这两种用法，我们通常只要记住to作介词的一些短语，例如： get down to着手做， find one's way to设法达到， admit to承认， take to喜欢上， make it to成功的到达， look up to尊敬， lead to导致， put one's mind to致力于，全神贯注于， look forward to期盼(盼望)， stick to坚持， object to反对， be used to习惯于， devote oneself to献身于， object to反对等。 3．主动表被动 动名词作need, want, require, be worth等这些词的宾语，用主动形式表示被动意义。 This book is worth reading.这本书值得一读。 This bike needs repairing.这辆自行车需要修理。 用所给词的适当形式填空 1．All the children are looking forward to 　 going　 (go) forward to feed the panda. 2．The bird was lucky and it just missed 　 being caught　 (catch)． 3．—Maybe you've forgotten 　 to post　 (post) my letter. —How could I? I remember 　 putting　 (put) it into the letter box. 4．When it comes to 　 speaking　 (speak) in public, many people are nervous at first. 5．We've had a good start, but next, more work needs　 doing/to be done　 (do) to achieve the final success. 6．　Walking　(walk) is a good form of exercise for both men and women. 7．—What made Jane so upset? —　Losing　 (lose) the ring her husband bought her for her birthday. 8．　Finding　(find) a job in such a big company has always been beyond his wildest dream. Ⅰ.用所给词的适当形式填空 1．　Understanding　(understand) your own needs and styles of communication is as important as learning to convey your affection and emotions. 2．　Knowing　(know) basic first aid techniques will help you respond quickly to emergencies. 3．It's no use　 speaking　 (speak) without taking action. 4．They avoid 　 going　(go) out alone after dark. 5．They put off 　 holding　(hold) the opening ceremony because of the bad weather. 6．Our monitor suggested　 having　(have) a discussion of this subject. 7．In some parts of London, missing a bus means 　 waiting　(wait) for another hour. 8．After the professor finished　 reading　(read), the whole class was silent. 9．Would you mind 　 lending　(lend) me your new car? 10．We may consider　 offering　(offer) you technical assistance to help you develop new product.

One day，Franklin's picture of a beautiful rainbow won first prize(一等奖)in his class.He took the picture home.“Look at this！Franklin got a prize.Put the picture up on the wall over there！” said his fathre. When the picture was on the wall，Franklin stepped back(后退)to look at it.“Do you think，”he said quietly，“it would look nicer if the wall were cleaner？”“Maybe you're right，son.Let's give it a try，” said his father. The family cleaned the wall together.Then，they cleaned the floor and washed the curtains(窗帘)．After all of the work was done，they all had a bath. From then on，Franklin' s family tried to keep the house and themselves clean and 　neat　.Soon，Franklin invited his classmates to come over.Life became much happier for the family. [语篇解读]　Franklin是一头小猪，它的家里总是很脏。一天，它的画得了一等奖，它的家人决定把画贴在墙上，但是发现墙太脏了，于是开始打扫。从那以后，它们总是把家里打扫得干干净净，生活也变得更幸福了。 1．Why did Franklin never invite his friends to his home at first? A．His home was too small. B．His parents were too busy. C．His home was too dirty. D．His parents thought it would be noisy. 解析：C　[细节理解题。根据第一段中的“He never invited(邀请)anyone to his home.It was dirty.”可知，Franklin从来不邀请任何人去家里，这是因为它家太脏了。] 2．Where did they put the picture? A．On the wall. B．On the floor. C．On the desk. D．By the window. 解析：A　[细节理解题。根据第二段中的“Put the picture up on the wall over there！”和第三段第一句中的“When the picture was on the wall”可知，它们把画贴在了墙上。] 3．What is the right order(顺序)of the following things? ①The family had a bath. ②The family cleaned the wall. ③The family cleaned the floor. ④The family washed the curtains. A．①②③④ B．①③②④ C．②③④① D．②④③① 解析：C　[细节理解题。根据第四段中的描述可知，Franklin和家人首先清洁了墙壁，然后清洁了地板并清洗了窗帘，最后洗了澡。] 4．What does the underlined word “neat” in the last paragraph probably mean? A．Different. B．Warm. C．Great.

D．Everyone should do the housework. 解析：B　[推理判断题。通读全文可知，Franklin一家从不讲卫生变得讲卫生之后，它们的生活也变得更幸福了。因此我们能从中学到的道理是：保持干净是好事。] B In 1937, famous mountaineers Bradford Washburn and Bob Bates set out to climb Mount Lucania－the thirdhighest mountain in Canada－for the first time in history. The pair flew to Walsh Glacier and began their journey in June.However, because of bad weather conditions, the two climbers had to travel as light as possible.So, they gave up their heavy equipment (装备), including three cameras, which they planned to come back for later.Though they did successfully reach the top of the mountain, they never returned to get their equipment. In 2020, skier Griffin Post read about the 1937 climb in a book and decided to search for the equipment.After doing some 3D mapping and seeing old photos, he got in touch with two glaciologists (冰川学家) and asked for their help to find the equipment. In late April, 2022, they made the journey.The team thought they had a pretty good idea of where the cameras were left in 1937, but the Walsh Glacier wasn't moving at a constant speed(不变的速度) from year to year like most glaciers.In fact, the team didn't succeed.But in August, they returned.After searching for six days, they finally found the cameras, tents, cooking equipment, etc., more than 12 miles from where they were left. Now, experts are working to keep the cameras in good condition and see whether any of the photos can be recovered(复原)．Even if the photos have been lost to time, finding their location provides important information on how the glacier has moved, according to ABC News. [语篇解读]　1937年，Bradford Washburn和Bob Bates去攀登加拿大的卢卡尼亚山，由于糟糕的天气状况，他们放弃了携带的重型装备。2022年8月份，Griffin Post和他的团队找到了当时被丢弃的装备。 6．Why did Bradford Washburn and Bob Bates leave the cameras? A．They were heavy. B．They were found useless. C．They were used as a mark. D．There was something wrong with them. 解析：A　[细节理解题。根据第二段中的“the two climbers had to travel as light as possible.So，they gave up their heavy equipment，including three cameras”可知，这两名登山者不得不尽可能轻装前行。因此，他们放弃了重型装备，包括三台照相机。由此可知，他们丢弃照相机是因为它们太重了。] 7．What did Griffin Post prepare before setting out? ①He did some 3D mapping. ②He looked through old photos. ③He read a book about Bob Bates. ④He turned to glaciologists for help. A．②③④ B．①②③ C．①③④ D．①②④ 解析：D　[细节理解题。根据第三段中的“After doing some 3D mapping and seeing old photos，he got in touch with two glaciologists and asked for their help to find the equipment.”可知，Griffin Post绘制三维地图，查看旧照片，并寻求冰川学家的帮助。再结合倒数第二段第一句“In late April，2022，they made the journey.”可知，在出发前他做了这些准备工作。] 8．What can we know about the team's journey in April? A．They stopped halfway up the mountain. B．They gave up heavy equipment. C．They didn't find the cameras' location. D．They found the Mount Lucania changed a lot. 解析：C　[细节理解题。根据倒数第二段中的“In fact，the team didn't succeed.”可知，他们没有成功，即他们没有找到照相机的位置。] 9．What is the last paragraph mainly about? A．The looks of the cameras. B．New ways to recover the photos. C．Proper ways to keep the cameras. D．The importance of finding the cameras. 解析：D　[段落大意题。通读最后一段可知，现在，专家们正在努力保持照相机的良好状态，看看是否能复原照片，即使这些照片已经随时间流逝而消失，但找到这些装备的位置也能提供关于冰川如何移动的重要信息。由此可推知，本段主要介绍了找到这些照相机的意义和重要性。] 10．What is the best title of the passage? A．Why is the Walsh Glacier special? B．Two special trips to Mount Lucania C．A team found cameras left in 1937 D．Why do people want to climb Mount Lucania? 解析：C　[主旨大意题。Griffin Post等人找到了1937年被登山员留下的照相机等装备，故C项“一个团队找到了1937年留下的照相机”为本文最佳标题。] Ⅳ.书面表达 每个人都是独一无二的，都有与众不同之处，人们喜欢你一定会有很多原因。请以“What Makes Me a Good Friend？”为题写一篇英语短文。 要求：1.语言表达准确，短文连贯通顺； 2．文中不得出现真实姓名和学校名称； 3．词数80－120。 What Makes Me a Good Friend? ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ [参考范文] What Makes Me a Good Friend?

It's so nice talking to you. 和你谈话很高兴。 It's no good smoking. You'd better give it up. 吸烟有害健康，你最好戒烟。 It's no use arguing with him. 和他争论是没有用的。 It's a waste of time waiting here. 在这里等是浪费时间的。 3．动名词和不定式作主语的区别： 不定式作主语，表示的是具体某一次的行为，用动名词作主语表示抽象或泛指的动作。通常两者可以相互转换，但是下面几种情况除外： (1)主语和表语要保持一致。也就是说，表语是动名词，主语也要用动名词，表语是不定式，主语也要用不定式。 Seeing is believing.还可以说成To see is to believe. (2)在句型It's no use/ no good doing；It's a waste of time doing等当中，通常用动名词。 It is a waste of time watching TV too much. 看太多电视是浪费时间的。 (3)但是在常用句型，It is＋adj.＋to do和It is＋adj.＋for/of sb.to do等当中，常用不定式。 It's necessary for us to learn English well. 学好英语对我们来说是很有必要的。 It's not difficult for you to finish the work on time. 对你来说按时完成这项工作不是很难。 二、动名词作宾语 1．一些动词后面通常接动名词作宾语： suggest，finish, admit，advise，avoid，can't help，consider，deny，enjoy，escape，excuse，leave off，mind等。 2．作介词的宾语 如最常用的一个例子，Thank you for helping me.谢谢你帮助我。 需要我们注意的是介词to的宾语。to既可以是介词，也可以是不定式符号，在学习中特别容易混淆。如果是介词，后面就接动名词；如果是动词不定式符号，后面就接原形。 针对这两种用法，我们通常只要记住to作介词的一些短语，例如： get down to着手做， find one's way to设法达到， admit to承认， take to喜欢上， make it to成功的到达， look up to尊敬， lead to导致， put one's mind to致力于，全神贯注于， look forward to期盼(盼望)， stick to坚持， object to反对， be used to习惯于， devote oneself to献身于， object to反对等。 3．主动表被动 动名词作need, want, require, be worth等这些词的宾语，用主动形式表示被动意义。 This book is worth reading.这本书值得一读。 This bike needs repairing.这辆自行车需要修理。 用所给词的适当形式填空 1．All the children are looking forward to 　 going　 (go) forward to feed the panda. 2．The bird was lucky and it just missed 　 being caught　 (catch)． 3．—Maybe you've forgotten 　 to post　 (post) my letter. —How could I? I remember 　 putting　 (put) it into the letter box. 4．When it comes to 　 speaking　 (speak) in public, many people are nervous at first. 5．We've had a good start, but next, more work needs　 doing/to be done　 (do) to achieve the final success. 6．　Walking　(walk) is a good form of exercise for both men and women. 7．—What made Jane so upset? —　Losing　 (lose) the ring her husband bought her for her birthday. 8．　Finding　(find) a job in such a big company has always been beyond his wildest dream. $$
