During the Yuan Dynasty,Marco Polo visited many major Chinese cities.He recorded the culture,customs and daily life of Chinese people.His experiences were later written into The Travels of Marco Polo. The book opened a window for Europeans to understand the East.Today,he is remembered as one of the greatest travelers in history.His journey shows that traveling can connect different cultures. 41．Where was Marco Polo from? A. Italy. B. China. C. France. 42．At what age did he start traveling? A. At age 22. B. At age 17. C. At age 30. 43．How long did he travel? A. Over 24 years. B. Over 10 years. C.

Travel connects cultures. 【答案】41．A 42．B 43．A 44．B 45．C 【导语】意大利旅行家马可·波罗的中国之旅。 【详解】根据第一段"Marco Polo was a famous traveler from Italy"可知他来自意大利，而非中国或法国。注意区分：中国是他旅行的目的地国家，而非国籍国。故选 A。 根据第一段"At age 17, he set off for his first trip"可知马可·波罗17岁出发。22岁是徐霞客的出发年龄，30年是另一位旅行者的年数，需仔细辨别不同旅行家的信息。故选 B。 根据第一段"He spent over 24 years traveling"可知他旅行超过24年。10年和30年均与文中数据不符——30年是徐霞客而非马可·波罗的旅行年份。故选 A。 根据第二段"The book opened a window for Europeans to understand the East"可知他的游记为欧洲打开了解东方的窗口。"Taught cooking"和"Showed tickets"都与文化交流功能无关。故选 B。 根据第三段"traveling can connect different cultures"可知旅行能连接不同文化。"Italy is bigger"是对地理信息的误读，"Travel wastes time"与全文积极态度相悖。故选 C。 B Earth Hour is a global event on the last Saturday of March.People turn off lights for one hour to show they care about climate change.It began in Sydney in 2007. By 2024,over 190 countries joined this activity.Many Chinese cities like Beijing and Hangzhou also take part.From 8:30 to 9:30 pm,lights go off.

Darkness is scary. 【答案】46．A 47．C 48．B 49．B 50．A 【导语】地球一小时活动及其全球影响。 【详解】根据第三段"on the last Saturday of March"可知地球一小时在三月最后一个周六。"First Sunday of April"和"January 1st"均非正确日期，属于时间信息干扰项。故选 A。 根据第三段"It began in Sydney in 2007"可知地球一小时始于悉尼。北京和伦敦虽然也是参与城市，但都不是活动的创始地。故选 C。 根据第三段"over 190 countries joined this activity"可知超过190个国家参与。50个和10个都远低于实际参与国家数量，与文中数据严重不符。故选 B。 根据第三段"People turn off lights for one hour"可知活动内容是关灯一小时。"Go shopping"和"Watch movies"都与活动的环保宗旨无关。故选 B。 根据第三段"small actions can make a big difference"可知活动传达"小行动能带来大改变"的理念。"Lights are bad"和"Darkness is scary"都是对关灯活动的片面理解。故选 A。 综合卷Ⅱ（25分） 四、英汉互译（共5小题，每小题3分，满分15分） 51．Xu Xiake never gave up his dream. _____________________________________________ 【答案】徐霞客从未放弃梦想。 【详解】考查翻译能力。考查翻译能力。give up放弃。 52．People who exercise have fewer illnesses. _____________________________________________ 【答案】经常锻炼的人疾病更少。 【详解】考查翻译能力。考查翻译能力。who定语从句。 53．Volunteers should be skilled in communication. _____________________________________________ 【答案】志愿者应擅长沟通。 【详解】考查翻译能力。考查翻译能力。be skilled in擅长。 54．我们应向旅行家学习永不放弃的精神。(learn from) _____________________________________________ 【答案】We should learn from travelers their spirit of never giving up. 【详解】考查翻译能力。考查翻译能力。learn from向……学习。 55．如果感觉更糟应预约看医生。(make an appointment) _____________________________________________ 【答案】If you feel worse,make an appointment to see a doctor. 【详解】考查翻译能力。make an appointment预约。 五、应用写作（满分10分） 56．假定你是李华,请写一篇短文介绍坚持梦想的重要性。(满分10分) 提示:1.描述一个坚持梦想的人物事例;2.说明坚持的意义;3.你的感受。 词数80—100词。 _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ The Power of Holding On to Dreams Xu Xiake is a great example of holding on to dreams.He dreamed of traveling across China.Although the journey was hard,he never gave up.He walked on foot for over 30 years and recorded everything he saw.
