At that point it had already been under construction for over a decade. It had been voted to be built nearly a quarter of a century ago! The idea to build it could date back to nearly 70 years ago—about as old as some of your grandparents!‎ Yesterday, it was finally ready!‎ It’s 35 miles long and runs 7,500 feet beneath the Swiss Alps, a famous mountain range in Switzerland. It even runs under an old tunnel that was there before. It took a total of 17 years to build at a cost of $12 billion.128 million tons of rock were dug. Two million truckloads of earth were removed!‎ The tunnel connects northern and southern Europe. The opening of this runnel was such a big deal that the Germany’s leader, Chancellor Angela Merkel, France’s president, Francois Hollande, and Italy’s prime minister, Matteo Renzi, were all there to celebrate, as was Austria’s chancellor Christian Kern.‎ It’s called the Gotthard Base Tunnel.Eventually,325 freight and passenger trains will go through the tunnel, relieving a lot of traffic on the roadways there and making it ‎ a more environmentally friendly option. The Gotthard Base Tunnel is a wonder of engineering! Make us want to visit it!‎ ‎6.When did people first have the idea of building the Tunnel?‎ A.About 70 years ago. B.Half a century ago.‎ C.Twenty-five years ago. D.Seven years ago.‎ ‎7.What can we learn about the Tunnel?‎ A.It used to be an old tunnel.‎ B.It has just been completed.‎ C.It connects all European countries.‎ D.It runs over a range of mountains.‎ ‎8.What may be the purpose of building the Tunnel?‎ A.To improve traffic. B.To increase employment.‎ C.To attract donation. D.To stop pollution.‎ ‎9.What can be inferred about the Tunnel?‎ A.It will cause conflicts among countries.‎ B.It will be of little benefit to the locals.‎ C.It may do damage to the environment.‎ D.It may become a tourist attraction.‎ Ⅱ.语法填空 ‎(2018安徽高中十校联盟高三摸底) ‎ 阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。‎ One of the biggest challenges　1　 (face) by students today is how to concentrate on studies.

There was a large number of people in the crowded train, but everyone help those who had lots of baggage and behaved politely. Along the way, we enjoyed beautifully views. At first, we saw one hill after another. Then what came into our eye were fields with green crops. In a six-hour trip, we arrived at my grandparents’ house. Exhausted though I felt, but I was happy to see my grandparents, which I hadn’t seen for a long time. It’s really an excited trip because it was the first time I had taken so a long-distance train.‎ 答案精解精析 Ⅰ.阅读理解 A ‎[语篇解读]　本文主要讲述了克隆技术对人类的一些有利的方面。‎ ‎1.C　主旨大意题。根据第一段中的is expected to benefit mankind及下面的内容判断,文章主要谈论的是human cloning的优点。‎ ‎2.B　推理判断题。根据第二段的to reverse the aging process推断,利用克隆技术可以使人们长寿。‎ ‎3.D　推理判断题。根据第三段可知,心脏病是美国和其他工业化国家的头号杀手,因此死于心脏病的人要比死于其他疾病的人多。‎ ‎4.A　主旨大意题。最后一段的主要意思是“利用克隆技术可以使不能生育的夫妇有自己的孩子”,所以用A项作小标题。‎ ‎5.B　细节理解题。由第四段中的that will be free of rejection by their immune systems可知,用自己的细胞克隆的器官不会有排斥反应。 ‎ B ‎[语篇解读]　本文介绍了一条世界上最长的铁路隧道建在瑞士的阿尔卑斯山脉,是隧道工程的奇迹。‎ ‎6.A　细节理解题。根据第一段中的“The idea to build it could date back to nearly 70 years ago”可知,选A。 ‎ ‎7.B　细节理解题。根据第二段“Yesterday, it was finally ready!”可知,这条隧道已经竣工。故选B。‎ ‎8.A　细节理解题。根据最后一段中的“relieving a lot of traffic on the roadways there and making it a more environmentally friendly option.”可知,建成这一隧道,有大量的货运和客运车通过隧道,缓解了道路上的交通。故选A。 ‎ ‎9.D　推理判断题。根据文章最后的“The Gotthard Base Tunnel is a wonder of engineering! Make us want to visit it!”可推知这条隧道可能会成为旅游景点。故选D。‎ Ⅱ.语法填空 ‎[语篇解读]　我们生活在一个处处有分心事物的时代,我们需要慢慢学会如何排除分心事物对我们的干扰。‎ ‎1.faced　考查非谓语动词。challenges与face为被动关系,故用过去分词短语作后置定语。‎ ‎2.when　考查定语从句的关系词。名词age后接定语从句,关系词在定语从句中作时间状语,故用when。‎ ‎3.factors　考查名词复数。由前面的one of可知这里应用复数名词,故用factors。‎ ‎4.is　考查主谓一致。此句主语是One of the most important factors,所以谓语动词用单数,故用is。‎ ‎5.easily　考查副词。这里用副词修饰动词focus,故用easily。‎ ‎6.exception　考查名词。be no exception没有例外,也不例外。 ‎ ‎7.to ensure　考查不定式。need to do...需要做……。 ‎ ‎8.but　本题考查固定搭配。not...but...不是……而是……。‎ ‎9.a　考查冠词。a distraction-free environment一个没有使人分心的事物的环境。故用a。‎ ‎10.like　考查介词。此处like为介词,意为“像”。‎ Ⅲ.短文改错 ‎　　Last Saturday, my parents and I paid ① visit to my grandparents by train.
