Section Ⅱ　Discovering Useful Structures 动词－ing形式作主语 　　Li Hua is addicted to searching for information on the Internet．His mother is worried about his health and advises him to surf the Internet properly， but it is no use persuading him① because he won’t listen．This is what his job requires．His mother wants him to change his job， but he likes it and enjoys it．Staying up late② has become his habit．There is no way， otherwise he will not finish the task assigned by the leader．In my opinion， working hard③ is one thing and having a good rest④ is another．There is no denying that we should form a good routine． ①处it作形式主语，动词－ing短语persuading him作真正的主语； ②处动词－ing短语Staying up late作主语； ③处动词－ing短语working hard作主语； ④处动词－ing短语having a good rest作主语。 ——运用“形式—意义—使用”相结合的三维动态语法观 一、动词－ing形式作主语 【先感悟】 ①（教材典句）Getting here is quite difficult， so apart from the Sami very few people have ever seen Sarek． ②（教材典句）For hundreds of years， looking after reindeer was a way of life for the Sami． ③（外研选必三）Creating buildings such as these enables us to live in closer harmony with our environment． 【会发现】 动词－ing形式可以作句子的主语，常将其看作一个整体，谓语动词用第三人称单数形式。 【善归纳】 1.动词－ing形式作主语时，多表示经常性、习惯性的动作。 2.动词－ing形式作主语时的主谓一致： （1）单个的动词－ing形式作主语时，谓语动词用第三人称单数形式； （2）意义不同的两个（或两个以上）动词－ing形式并列作主语时，谓语动词用复数形式。 【运用练】　单句语法填空/完成句子 ①（2025•全国一卷）Writing （write） down these happy experiences can help us appreciate the bright side of school and share happiness with others． ②（2026•1月浙江卷）Protecting （protect） public reading resources is our responsibility， for library books serve every student and are shared treasures of our campus． ③（2026•1月浙江卷） We should stop such uncivilized behavior and remember that treating （treat） books with care is a sign of good manners． ④Having a good command of English puts me at an advantage over other students． 精通英语使我比其他学生更有优势。 二、用it作形式主语代替动词－ing形式 【先感悟】 ①Actually， I understand it’s very painful， but it’s no use getting upset about it all day long． ②In my opinion， it’s useless quarrelling with him． ③（2025•全国二卷） In my opinion， it is a waste of time explaining the meaning of my name to them． ④It is worthwhile wandering in this beautiful valley and admiring its splendid waterfall． 【会发现】 it作形式主语代替动词－ing形式时，只限于某些句型中，并不是所有的动词－ing形式作主语都可用it作形式主语。 【善归纳】 用it作形式主语代替动词－ing形式的常用句型： 1.It is＋形容词＋doing sth It is/feels funny doing sth做某事（感觉）很有趣 It is useless doing sth 做某事无用 It is worthwhile doing sth 做某事是值得的 2.It is＋名词＋doing sth It’s a waste of time doing sth 做某事是浪费时间 3.It is no＋名词＋doing sth It’s no good/no use/no fun doing sth 做某事没好处/没用/没意思 【运用练】　完成句子 ①It is no use trying to persuade him to have a holiday because he is a work addict． 努力说服他去度假是没有用的，因为他是个工作狂。 ②In my opinion， it is a waste of time playing computer games． 在我看来，玩电脑游戏是浪费时间。 三、动词－ing形式的复合结构 【先感悟】 ①The president’s attending the meeting gave them a great deal of encouragement． ②His coming made me quite glad and we chatted excitedly for over an hour． ③His son’s winning first prize made him quite proud． 【会发现】 动词－ing形式也有动作的发出者，其发出者叫逻辑主语；带有逻辑主语的动词－ing形式，其否定形式是把not放在动词－ing形式的前面。 【善归纳】 动词－ing形式的复合结构的构成： 1.名词所有格/名词的普通格＋doing（如Mary’s/Mary marrying） 2.形容词性物主代词/人称代词的宾格＋doing （如his/him coming） 【指津】　如果动词－ing形式的复合结构作主语，其逻辑主语只能用形容词性物主代词或名词所有格。 【运用练】　完成句子 ①他早上起晚了，导致他上课迟到了。 His getting up late in the morning made him late for class． ②他们来帮忙对我们来说是很大的鼓舞。 Their coming to help was a great encouragement to us． ③不知道下一步应该做什么使杰克不知所措。 Not knowing what to do next made Jack at a loss． ◇prohibit vt．（尤指以法令）禁止；阻止→prohibition n．禁止；阻止；禁令 教材原句　Officially or legally prohibit．正式或依法禁止。 【用法】

　　（2026•广东肇庆高二上期中）As much as I love the rides in theme parks， my favorite part of the experience is the live entertainment．Whether it’s a parade， stage show，“streetmosphere”， or even an impressive nighttime show， I just love the energy that a live performance can bring to a space．It is not uncommon for me to visit a theme park and go on one ride and spend the rest of the time just enjoying the atmosphere． 　　No matter how many times I ride an attraction， I’m having the same experience．But with live entertainment， it constantly changes．Different performers bring their own touch to the show．Even when things go wrong in a live situation， I find it fascinating to see how it is covered．There is an impressive art of fixing an error， or sometimes even making it a comedic moment． 　　But because these live performances aren’t bolted （固定） to the ground and are easily influenced， they are often the first thing to get removed from the parks when there is a shortage of money．As much as I understand this business decision， it feels shortsighted．The parks simply don’t feel alive when live entertainment is missing．Without it， a theme park is just a group of people walking quickly from one ride to the next． 　　We are certainly living in an unprecedented time， but I’m happy to see that theme parks have found creative ways to make sure there is some sort of live entertainment put on safely．Most parks are having their characters and performances visible from a distance． 　　One of my favorite examples of this was shared by someone on a website， where Winnie the Pooh was frolicking around EPCOT and trying to catch a butterfly．This is such a great example of what can be done with characters and live entertainers in a time when the “norm” isn’t possible．I honestly hope that these special moments remain once it’s safe for the meet－and－greets and close－up interactions to return． 语篇解读：本文是一篇夹叙夹议文。作者认为主题公园里的现场娱乐表演让公园更有活力，让游客体验更好。 1.What does the author like best in a theme park？（　　） A．Joining its parades． B．Observing its visitors． C．Trying its various rides． D．Enjoying its live shows． 解析：D　细节理解题。根据第一段第一句可知，作者在主题公园里最喜欢做的事情是欣赏现场表演。 2.What does the underlined word “it” in paragraph 2 refer to？（　　） A．The error．　 B．The show． C．The reason．　 D．The attention． 解析：A　代词指代题。根据画线词所在句和下文可知， it指代上文提到的things go wrong，即下文的“error”。 3.What does the author think of the business decision in paragraph 3？（　　） A．It will bring theme parks more business． B．It will make theme parks easily influenced． C．It will make theme park rides more popular． D．It will take away the liveliness of theme parks． 解析：D　观点态度题。根据第三段第二、三句可知，对于这个商业决策，作者认为它会带走主题公园的活力。 4.Why does the author mention Winnie the Pooh in the last paragraph？（　　） A．To explain what theme parks can do to stay alive． B．To show its popularity among theme park visitors． C．To explain what characters can do to get closer to visitors． D．To show the influence special times can have on theme parks． 解析：C　推理判断题。根据最后一段内容可知，作者希望在近距离互动保证安全的时候，可以把像小熊维尼捕捉蝴蝶这样的特殊互动保留下来。由此推断，提到小熊维尼是为了解释主题公园里角色可以做些什么接近观众。 Ⅱ．阅读七选五 　　（2026•晋城高二期中） How to Be Hopeful About the Future 　　It can be tough to believe that good things are coming your way when your hopes and dreams haven’t yet been realized． However， staying hopeful about your future can help you remain positive， even when things don’t go as planned． Here are some strategies to help you stay hopeful． 　　Have a positive attitude 　　5.　　． “Positive energy leads positive experiences， and negative energy leads negative experiences，” says life coach Alionka Polanco． By keeping a positive attitude， you can attract great things， even if you’re unsure of what your future holds． 　　Imagine what your future will look like 　　You’re most likely to achieve something great if you can already imagine yourself in that situation． Every morning， you can take a few minutes to intentionally daydream about what your life will look like in 10 years． 6.　　． Once a week， try to imagine where you want your life to be by writing it down in a journal or talking about it with someone you care about． 　　Connect with a life coach 　　Sometimes it can be hard to determine what you want out of life when you might not be aware of where exactly you want your life to be in the next few years． A life coach can help guide you in the right direction． 7.　　． Working with a coach can help you stay hopeful about your future． 　　Remove any negative thoughts about the present 　　Your future won’t look great if you’re negative about the present． 8.　　． The quote “this too shall

practice can create excitement and inspiration D．How you handle current problems affects your future E．They can help you figure out what you truly want out of life F．They should take action in the

most popular theme park． 语篇解读：本文是一篇说明文。文章介绍了香港海洋公园的特色、地理位置以及游玩建议等。 25.attractions　考查名词复数。空处被定语greatest修饰， 应用attract的名词形式attraction， tourist attraction意为“观光胜地， 旅游景点”， 且前有one of限定， 说明旅游景点不止一个， 名词attraction应用复数形式。故填attractions。 26.compared　考查非谓语动词。分析句子结构可知， 句子主干成分完整， 空处作句子的方式状语，应用非谓语动词形式， compare与逻辑主语it之间为逻辑上的动宾关系， 应用compare的过去分词形式。故填compared。 27.has drawn/has been drawing　考查时态和主谓一致。根据时间状语since its opening可知， 动作从过去开始发生， 对现在造成影响， 或表示动作会继续进行下去， 应用现在完成时或现在完成进行时。主语the park为单数， 所以助动词用has。故填has drawn/has been drawing。 28.Covering　考查非谓语动词。分析句子结构可知， 句子主干成分完整， 空处用非谓语动词作句子的伴随状语， cover与逻辑主语the theme park之间为主谓关系， 应用cover的动词－ing形式， 且空处位于句首， 首字母需大写。故填Covering。 29.before　考查连词。根据As the park attracts large crowds every day可知， 公园里游客较多， 所以要在早上10点公园开放之前到达， 空处应用连词before， 意为“在……之前”。故填before。 30.（should） be bought　考查虚拟语气和语态。句中recommend意为“建议”， that引导的宾语从句需用虚拟语气，从句的谓语部分用should do的形式， should可以省略， 且tickets和buy之间是被动关系，应用被动语态。故填（should） be bought。 31.to pay　考查非谓语动词。空处作目的状语，应用动词不定式。故填to pay。 32.with　考查介词。空处在which引导的非限制性定语从句前， 从句对先行词The card进行补充说明，表示“用这张卡可以在公园里买东西”，故填with。 33.it　考查代词。分析句子结构可知， 此处为have sth done结构， 表示“使某事被做”， 联系上下文语境可知， 空处指的是上文的The card。故填it。 34.enjoyable　考查形容词。空处修饰名词day， 作定语， 应用enjoy的形容词形式， 意为“令人愉快的”。故填enjoyable。 1 / 2 学科网（北京）股份有限公司 $
