A.亞歐板塊與印度洋板塊B.亞歐板塊與美洲板塊

C.亞歐板塊與北冰洋板塊D.亞歐板塊與太平洋板塊

【答案】

【1】C

【2】D

【解析】

【1】大陸漂移假說(shuō)是20世紀(jì)初魏格納提出的。大陸漂移假說(shuō)認(rèn)為，地球上原先只有一塊叫“泛大陸”的龐大陸地，被叫做“泛大洋”的廣袤海洋所包圍。大約兩億年前，泛大陸開(kāi)始破裂，碎塊像浮在水上的冰塊一樣向外越漂越遠(yuǎn)。距今大約兩三百萬(wàn)年前，形成現(xiàn)在七大洲，四大洋的基本面貌。德國(guó)科學(xué)家魏格納在偶然翻閱世界地圖時(shí)發(fā)現(xiàn)：大西洋的兩岸﹣﹣歐洲和非洲的西海岸遙對(duì)南北美洲的東海岸，輪廓非常相似，這邊大陸的凸出部分正好能和另一邊大陸的凹進(jìn)部分湊合起來(lái)，他堅(jiān)信這不是巧合，便順著這條思路研究下去，后來(lái)提出了大陸漂移假說(shuō)。故選C。

【2】日本位于亞洲東部、太平洋西北部。領(lǐng)土由北海道、本州、九州、四國(guó)四個(gè)大島以及附近一些小島組成；日本的海岸線慢長(zhǎng)，沿岸多島嶼、半島、海灣和天然良港。日本位于亞歐板塊和太平洋板塊的交界處，地殼比較活躍，多火山地震。故選D。

該題考查大陸漂移學(xué)說(shuō)和板塊運(yùn)動(dòng)的影響。

【題目】《我不是藥神》

Ning Hao and Xu Zheng have come together again to produce a new film—Dying to Survive《我不是藥神》— as they return to the summer movie season after 12 years.

This time, director Wen Muye joined the team after Ning Hao recognized his talent for showing true themes. It was Ning Hao who handed Wen Muye the play and asked Xu Zheng to act as the leading role. The film is about Cheng Yong, played by Xu Zheng, a medicine salesman who becomes a hero by helping people get cheaper cancer medicine. The 117minute film connects both laughter and tears together, showing up the kindness of one man against the reality of society.

“It's touching because it pays attention to the better side of people, and you can see how society changes, thanks to just one small act of kindness，” said Xu Zheng at the film premiere(首映) at Tsinghua University in Beijing on July 2.

The movie is based on a true story—Lu Yong, who got cancer in 2002, helped more than 1，000 patients get cheaper but unapproved(未經(jīng)批準(zhǔn)的) medicine from India.

He agreed with the message at the end of the movie that the situation was being improved thanks to the recent efforts of government.

Actor Huang Xiaoming was also invited to the premiere, and he thought both the acting and the direction were wonderful. “Even though I'm not in the movie, as a filmmaker, I feel proud to watch this piece，” he said.

【題目】閱讀下列材料回答相關(guān)問(wèn)題

厲害了！我的國(guó)

（一）西成高速鐵路，簡(jiǎn)稱“西成高鐵”，是國(guó)家八縱八橫高鐵網(wǎng)絡(luò)規(guī)劃中“京昆通道”的重要組成部分。高鐵自西安北站引出，自北向南穿越關(guān)中平原、秦嶺山脈、漢中平原、巴山山脈進(jìn)入四川盆地，與成綿樂(lè)城際鐵路相連，接入成都東站。西成高鐵全線于2017年12月6日開(kāi)通運(yùn)營(yíng)，西安至成都的運(yùn)行時(shí)間將由普快11個(gè)小時(shí)縮短為4小時(shí)。

（二）2017年11月28日，由中國(guó)國(guó)電集團(tuán)公司與神華集團(tuán)有限責(zé)任公司合并重組的國(guó)家能源投資集團(tuán)有限責(zé)任公司在北京正式成立。據(jù)悉，重組后的國(guó)家能源集團(tuán)資產(chǎn)規(guī)模超過(guò)1.8萬(wàn)億元，擁有33萬(wàn)名員工、8家科研院所、6家科技企業(yè)。擁有四個(gè)世界之最，分別是世界最大的煤炭生產(chǎn)公司、世界最大的火力發(fā)電生產(chǎn)公司、世界最大的可再生能源發(fā)電生產(chǎn)公司和世界最大煤制油、煤化工全司。

（四）港珠澳大橋是中國(guó)的一座跨海大橋，是連接香港、珠海、澳門(mén)的超大型跨海通道。全長(zhǎng)55公里，建成后將成為世界最長(zhǎng)的跨海大橋。其中，工程量最大、技術(shù)難度最高的是長(zhǎng)約29.6公里的橋一島一隧集群的主體工程。主體工程“海中橋隧”長(zhǎng)35.578公里，其中海底隧道長(zhǎng)約6.75公里。建成后將會(huì)為G4 -京港澳高速以及G94 -珠三角環(huán)線高速的一部分。

港珠澳大橋沉管隧道是全球最長(zhǎng)的公路沉管隧道和全球唯一的深埋沉管隧道，生產(chǎn)和安裝技術(shù)有一系列創(chuàng)新，為世界海底隧道工程技術(shù)提供了獨(dú)特的樣本和寶貴的經(jīng)驗(yàn)。2017年11月14日，港珠澳大橋主體工程荷栽試驗(yàn)完成，于2018年元旦建成通車。
