A lot of the story below is true...but did it really happen quite like this? Our story begins not in the icy cold waters of the North Atlantic，but rather thousands of miles away in Egypt.It is here，perhaps，that we can find the start of the mystery of the Titanic，in the year 1910，in the great city of Cairo.One day，a famous professor of Egyptian history called Douglas Murray was staying in Cairo，when he was contacted by an American adventurer. The American had something unusual to offer Murray，something that was certain to thrill him：a beautiful ancient Egyptian mummy case，containing the mummy of an Egyptian queen.It was over 3,000 years old，but in beautiful condition—gold，with bright paintings on it.Murray was delighted with both the object and the asking­price.He gave the man a cheque immediately. The cheque was never cashed.That evening the American adventurer died.For his part，Murray arranged to have the treasure sent back to Britain.However，it was not long before he learnt more about the beautiful mummy case：On the walls of the tomb in which it had been discovered，there were messages which warned of terrible consequences to anyone who broke into the tomb.Murray was disbelieving of these warnings until a few days later，when a gun he was holding exploded in his hand，shattering his arm.The arm had to be cut off. After the accident，Murray decided to return to his homeland.On the return journey，two of his companions died mysteriously，and two servants who had handled the mummy also passed away.The now­terrified Murray decided he would get rid of the cursed case as soon as he arrived in London.A lady he knew named Janet Jones said she would like it，so he gave it to her.Shortly afterwards，Jones’ mother died，and she herself caught a strange disease.She tried returning the mummy，but naturally Murray refused it.In the end，it was presented to the British Museum. Even in the museum，the mummy apparently continued to cause strange events.A museum photographer died shortly after taking pictures of the new exhibit；and a manager also died for no apparent reason.In the end，the British Museum decided to get rid of the mummy too.They sold it to a collector in New York. At the start of April 1912，arrangements for the transfer were complete，and the mummy began the journey to its new home.But the New Yorker never received the mummy or its case.For when the Titanic sank，one of the objects in its strong room was the mummy case.Or so they say. 1．In Paragraph 5，the underlined word “cursed” is closest in meaning to “ ”． A．forgotten B．uncommon C．unlucky D．expensive 2．In what order did the following events occur? a．The case was given to the British Museum. b．Janet Jones caught a mysterious illness. c．Murray’s arm was cut off. d．The mummy case was sold to an American. e．A man who took a picture of the case died. f．Warnings were written on the tomb’s walls. A．f，c，b，a，e，d B．c，f，b，a，e，d C．d，f，b，c，a，e D．f，a，c，b，e，d 3．According to the passage，where is the Egyptian mummy now? A．At the British Museum. B．In New York. C．In Egypt. D．Under the sea. 4．What’s the main purpose of this passage? A．To introduce an important historical event to readers. B．To entertain readers with a story of mystery. C．To warn readers about the dangers of mummies’ curses. D．To inform readers about the true cause of the Titanic’s sinking. B Solar power is helping bring about a future of cleaner energy，but there are limits to where rigid solar panels (刚性太阳能电池板) can go.A new kind of solar cell made with a mineral called perovskite(钙钛矿) can go almost anywhere，says physicist Olga Malinkiewicz.We can use perovskite cells on the surfaces of the building，on the roofs of the buildings，on the roofs of the cars and on the electronic devices.We can use it on the sails.We can use it in the balls，tents and unlimited applications.Malinkiewicz says perovskite has become a favorite among solar panel researchers.Because it can be printed，everyone can use it on every surface. Malinkiewicz developed a way to print perovskite panels like an inkjet printer.She co­founded a company to produce them，called Soleil Technologies，after the Baltic sun goddess.Construction company Skanska is testing the panels at their Warsaw headquarters.Adam Targowski is sustainable(可持续的) development manager for Skanska.They work perfectly，even when they are not well exposed to sunlight.So we can use them in all surfaces of the building.Soleil calculates that about one square meter of panel can supply a day’s worth of power for one worker’s computer and lights.And they keep getting better as research continues，says the company’s scientific director Konrad Wojciechowski. For other technologies，it took decades to really enter markets.Perovskite has been around only for few years in scientific research，so there is still a lot to be done，but potential is basically pretty much unlimited，I think.There are still durability and other problems to work out，but several companies expect to have perovskite panels on the market this year. 5．What do we know about the perovskite solar cell from the first paragraph? A．It’s delicate. B．It’s complex. C．It’s flexible. D．It’s expensive. 6．What does the underlined word “they” in the second paragraph refer to? A．Skanska and Adam Targowski. B．Malinkiewicz and Skanska. C．Soleil Technologies. D．Perovskite panels. 7．What can we infer from the last paragraph? A．It needs years to put perovskite panels into markets. B．Scientists think perovskite panels are ready for markets. C．Perovskite has been studied for decades. D．Perovskite panels will soon be seen in the market. 8．What is the main purpose of the passage? A．To explain how to use perovskite panels. B．To introduce perovskite panels. C．To advertise a new solar power cell. D．To propose scientists to further study perovskite cells. Ⅴ.七选五 The world is designed for right­handed people，but why does a tenth of the population prefer the left? 1 The answer to it remains a mystery.Since scientists have noticed that left­handedness tends to run in families，it’s assumed that left­handedness has a genetic(基因的) component to it. 2 In fact，identical(相同的) twins，who share the same genes，can sometimes prefer to use different hands.There are also plenty of theories on what else might determine which hand you write with，but many experts believe that it’s kind of random. Historically，the left side and left­handedness have been considered a negative thing by many cultures. 3 In some areas，the left hand became known as the “unclean” hand.In many religions，the right hand of God is the favored hand.For example，Jesus sits at God’s right side.God’s left hand，however，is the hand of judgement.Various activities and experiences become rude or even signs of bad luck when the left hand becomes involved.In some parts of Scotland，it is considered bad luck to meet a left­handed person at the start of a journey. 4 A person giving directions will put their left hand behind them and even physically try to point with their right hand if necessary.In some Asian countries，eating with the left hand is considered impolite. 5 People come to realize that left­handedness is natural.People even noticed that many famous people are left­handed，including Benjamin Franklin，Leonardo da Vinci，and Charlie Chaplin.Some researchers find out that lefties(左撇子) are more creative and can deal with abstract thinking better.The left­handedness is more easily adaptable to the right­handed world as well.Being left­handed is no longer a sad story now; instead，it is a wonderful gift or maybe it is something you should take pride in. A．In other words，left­handers are born that way. B．Left­handedness used to be regarded as a disability. C．The unfavorable associations of the use of the left hand among cultures are varied. D．Why do they prefer to use their left hand rather than their right hand for routine activities? E．Why do some parents force their left­handed children to become right­handed when writing? F．In Ghana，pointing，gesturing，giving or receiving items with the left hand is considered rude. G．Fortunately，nowadays most societies and cultures no longer reject left­handedness like before. Ⅳ.阅读理解 A 语篇解读　本文主要通过分析与古埃及的木乃伊接触过的人的神秘死亡，来猜测泰坦尼克号的沉没是否与埃及的木乃伊有关。 1. 答案　C 解析　词义猜测题。第四、五段讲述了与Murray同行的人员的相继死亡与失踪，因此可推知，该词表示“不祥的”。故选C。 2. 答案　A 解析　细节理解题。根据文章的内容可知，美国探险家把木乃伊卖给了Murray；Murray看到了坟墓中墙上的警告；接下来，Murray的胳膊被截去，他的同伴也相继死去或失踪；Murray回到英国后将木乃伊卖给了Janet Jones，但是之后Janet Jones得了一种奇怪的疾病，她想归还给Murray，却遭到了拒绝，所以木乃伊被送到了大英博物馆；但是不幸的事情又发生了，给它拍照的摄影师也死了；最后木乃伊被卖给了纽约的一位收藏家，可是对方并没有得到它，因此石沉大海。故答案选A。 3. 答案　D 解析　细节理解题。根据文章最后一段的内容可知，最后一次转卖是英国博物馆把它卖给纽约的一位收藏家，但是对方没有得到它，因为它随着运送它的泰坦尼克号一块沉入了海底。故选D。 4. 答案　B 解析　写作意图题。文章通过分析与古埃及的木乃伊接触过的人的神秘死亡，来猜测泰坦尼克号的沉没是否与埃及的木乃伊有关。作者是想通过神秘故事来娱乐读者。故选B。 B 语篇解读　本文是一篇说明文。文章主要介绍了一种新型的太阳能电池——钙钛矿电池板的优点和前景。 5. 答案　C 解析　细节理解题。根据第一段的第二句“A new kind of solar cell made with a mineral called perovskite(钙钛矿) can go almost anywhere...”可知，钙钛矿太阳能电池没有安装位置的限制，由此可知它具有灵活性，故C项正确。 6. 答案　D 解析　代词指代题。根据画线词前的内容可知，斯堪雅建筑公司正在测验这种电池板，画线词所在句是说的结果：不管是否完全置于日光下，这种钙钛矿电池板都特别好用，由此可知they指代的就是前面提到的钙钛矿电池板，故D项正确。 7. 答案　D 解析　推理判断题。根据文章最后一句中的“...but several companies expect to have perovskite panels on the market this year.”可知，一些公司已经打算今年在市场上出售钙钛矿电池板了。由此可知，很快就能在市场上看到钙钛矿电池板，故D项正确。 8. 答案　B 解析　写作意图题。通读全文，特别是根据第一段中的“A new kind of solar cell made with a mineral called perovskite(钙钛矿) can go almost anywhere...”可知，本文主要介绍了一种新型太阳能电池——钙钛矿电池板的优点和前景。由此可知，本文的目的就是介绍钙钛矿电池板，故B项正确。 Ⅴ.七选五 语篇解读　本文是一篇说明文，主要介绍了左撇子形成的原因和过去不同文化的人们以及当前人们对左撇子的不同态度。 1．答案　D 解析　根据上一句“为什么十分之一的人更喜欢使用左手？”和下文“The answer to it...”可知，此处也应是问句，D项承上启下，故选D项。 2．答案　A 解析　根据上文叙述的左撇子的形成有基因的原因，可以用A项对其进行同义解释，故选A项。 3．答案　C 解析　上文提到在许多文化背景下，左撇子被认为是不好的，由此可知，空处和文化有关，且C项中的关键词unfavorable与上文中的negative相呼应，故选C项。 4．答案　F 解析　根据上文提到的“In some parts of Scotland”以及下文的“In some Asian countries”并结合该空下一句中的giving directions等内容可知，此处为具体举例，故选F项。 5．答案　G 解析　最后一段的主要内容是现在人们开始意识到左撇子是很正常的，并且空处作为段落开头，G项符合本段大意，故选G项。 Ⅴ.完形填空 A gentleman lost his family when young.He was homeless and went to the local 1 every day.Although the church never let him in，they left one of the windows 2 so he could hear mass(弥撒曲)．It gave him 3 and comfort.Many times we would bring him into our home for a hot shower，or a hot meal.Those were the times when his eyes lit up，almost like he 4 everything he was going through.

Recently, I’ve done some research on Chinese characters. As a unique part of Chinese culture, they have a long history and various ways of creating new characters and expressing plentiful meanings. Here I’d like to introduce my favourite Chinese character to you. It is the character “想” that I am talking about, which consists of two parts. “相” is the sound element, while “心” indicates “thought” and “emotion”. In addition to the structure of the character, what attracts me most is its abundant meanings such as “missing”, “thought” and “imagination”, enabling people to express different meanings appropriately according to the contexts. So having a good command of Chinese characters can help you understand Chinese culture profoundly. If you have any interest in knowing more about Chinese characters, just let me know. Best wishes!
