Module 6 Unexplained Mysteries of the Natural WorldⅠ.阅读理解A(2019·江苏高考)In the 1960s, while studying the volcanic history of Yellowstone National Park, Bob Christiansen became puzzled about something that, oddly, had not troubled anyone before：he couldn't find the park's volcano. It had been known for a long time that Yellowstone was volcanic in nature—that's what accounted for all its hot springs and other steamy features. But Christiansen couldn't find the Yellowstone volcano anywhere.Most of us, when we talk about volcanoes, think of the classic cone (圆锥体) shapes of a Fuji or Kilimanjaro, which are created when erupting magma (岩浆) piles up. These can form remarkably quickly. In 1943, a Mexican farmer was surprised to see smoke rising from a small part of his land. In one week he was the confused owner of a cone five hundred feet high. Within two years it had topped out at almost fourteen hundred feet and was more than half a mile across. Altogether there are some ten thousand of these volcanoes on Earth, all but a few hundred of them extinct. There is, however, a second less known type of volcano that doesn't involve mountain building. These are volcanoes so explosive that they burst open in a single big crack, leaving behind a vast hole, the caldera. Yellowstone obviously was of this second type, but Christiansen couldn't find the caldera anywhere.Just at this time NASA decided to test some new high­altitude cameras by taking photographs of Yellowstone. A thoughtful official passed on some of the copies to the park authorities on the assumption that they might make a nice blow­up for one of the visitors' centers. As soon as Christiansen saw the photos, he realized why he had failed to spot the caldera: almost the whole park—2.2 million acres—was caldera. The explosion had left a hole more than forty miles across—much too huge to be seen from anywhere at ground level. At some time in the past Yellowstone must have blown up with a violence far beyond the scale of anything known to humans.篇章导读：本文是一篇记叙文。文章主要讲述了鲍勃探寻黄石国家公园火山的故事。1．What puzzled Christiansen when he was studying Yellowstone?A．Its complicated geographical features.B．Its ever­lasting influence on tourism.C．The mysterious history of the park.D．The exact location of the volcano.答案：D　细节理解题。根据第一段第一句可知，鲍勃感到迷惑的是，他在黄石国家公园没有找到火山，即：火山的准确位置。故选D项。2．What does the second paragraph mainly talk about?A．The shapes of volcanoes.B．The impacts of volcanoes.C．The activities of volcanoes.D．The heights of volcanoes.答案：A　段落大意题。文章的第二段主要介绍了两种类型火山的形成过程，一种是形成圆锥体形状的火山，富士山和乞力马扎罗山就是其典型代表；另外一种是通过爆裂岩浆而形成巨大裂口的火山，而黄石国家公园恰恰就是这一种，所以本段主要讲述了火山的形态，故选A项。3．What does the underlined word “blow­up” in the last paragraph most probably mean?A．Hot­air balloon.   B．Digital camera.C．Big photograph.   D．Bird's view.答案：C　词义猜测题。根据第三段“... a nice blow­up for one of the visitors' centers.As soon as Christiansen saw the photos ...”可知，the photos所指的就是前面提及的blow­up，所以推知blow­up相当于photo(photograph)，故选C项。B(2019·四川绵阳市高三第一次诊断性考试)When I was a kid, I was the girl who kept the training wheels on my bike as long as possible. Even my younger sister had got rid of them much earlier than me. But as I began to grow older, this changed.All this happened on the Bike Safety Day. It is supposed to be a fun day at school when all of us kids bring our bikes to school and the school provides us with the opportunity to ride outside and learn proper bike safety. Sounds like fun,  right?  No. In fact, it caused me to panic. What was I going to say when my friends asked me about my training wheels?With the pressure  of everyone  seeing my training wheels, I determined to let them go. This was the first big change I'd ever made on my own.I went to my parents and told them all about my dilemma. They were more than happy to help. We went outside and got my bike. Instead of running away and hiding behind, I stood in front of my bike and took great pride in my decision as my dad removed the training wheels.I got on and steadied myself. My heart raced but my feet and hands were calm. My dad started to push before my feet even moved and suddenly I was off. The fear faded away and a relaxed mind came into its place. It was crazy to think how quickly I learned something that took so long for me to even try!My confidence  soared (高涨). This was going to be the start of a brand new world for me. My accomplishment would carry me forth to new goals and wins. I realized that if I set my mind on doing something, I could achieve it.篇章导读：本文是一篇记叙文。文章讲述了作者小时候迟迟不敢去掉自行车的辅助轮，在学校“自行车安全日”来临之前因为害怕同学看见她的辅助轮而最终下决心去掉它们。4．What does the school expect the students to do on Bike Safety Day?A．Have their bikes checked.B．Ride outside for fun.C．Acquire bike safety skills.D．Remove the training wheels.答案：C　细节理解题。根据第二段中的“the school provides us with the opportunity to ride outside and learn proper bike safety”可知，学校想让学生在“自行车安全日”学会一些自行车安全技能，故选C项。5．What does the underlined word “them” in Paragraph 3 refer to?A．The author's friends.   B．The author's parents.C．The safety problems.   D．The training wheels.答案：D　指代判断题。根据语境及画线词所在句的前半部分“With the pressure of everyone seeing my training wheels”可知，作者迫于害怕别人看见自己的自行车辅助轮的压力才决心去掉它们，故画线词指的就是“辅助轮”，故选D项。6．What happened when the author finally rode without the training wheels?A．She felt extremely embarrassed.B．Everything turned out to be easy.C．She ended up falling down.D．Her sisters followed her example.答案：B　推理判断题。根据倒数第二段最后一句“It was crazy to think how quickly I learned something that took so long for me to even try！”可知，长时间不敢尝试的东西，作者竟学得很快，由此对于作者来说骑没有辅助轮的自行车后，事情变得容易了，故选B项。7．What does the author think is necessary for her to achieve a goal?A．Patience.   B．Determination.C．Pressure.   D．Concentration.答案：B　推理判断题。根据最后一段最后一句“I realized that if I set my mind on doing something, I could achieve it.”可知，作者意识到如果自己下定决心做一件事的话，自己就会做到。由此可推知，作者认为对于她来说实现一个目标的关键在于决心，故选B项。Ⅱ.七选五(2020·长沙市一中高三月考试卷(二))The Greener Grass SyndromeHave you ever met the situation where you kept thinking that there are better opportunities out there compared to your current one you are having? This is the syndrome when one is always looking at the other side of the fence and thinks that the grass is greener there. __1__Why are you like this? Uncertainty and curiosity play a big part in creating the “greener grass” syndrome. It is because we are uncertain of whether what we are holding onto now is the best for us and whether there are any better choices out there?   __2__ In fact, it sometimes does us more harm than good because often looking out for the “greener grass” will exhaust our energy and attention and finally we can grow even angrier, or at least more dissatisfied. __3__ We mostly prefer new over old because new things are fascinating and our curiosity keeps reminding us to explore the other side of the grass. These are the two factors that cause us to feel dissatisfied with what we have and always thinking of finding the greener grass at the opposite side.If you have this syndrome, chances are you are missing out lots of things you currently have now. So what can you do to cure the “greener grass” syndrome? The first thing is to recognize that your current job is your best choice right now. __4__     Secondly, always apply your best efforts to your current job. Otherwise, what can you make out of your job when you hardly devote any effort? Last but not least, always keep this truth in mind. The grass is always greener on the one side, and the other side is always greener no matter which side you are at. __5__A．Try to focus on “what is” instead of “what if”．B．Such uncertainty causes us to keep looking into alternatives.C．Humans are also curious by nature and we love new things.D．Focus on “what if” and seek for the best choice.E．Choose a side, stick to it and make the best out of it.F．This is what I call the “greener grass” syndrome.G．It has its own origin, primarily rooted in fantasy and fear.篇章导读：本文是一篇说明文。文章阐述了什么是“绿草坪综合症”，及其产生的原因、负面影响和解决的办法。1．F　根据该空前一句提到综合症和那里的草坪更绿可知，F项对本段的主题进行归纳总结，引出“绿草坪综合症”。故选F。2．B　根据该空前一段内容可知，我们的不确定性导致无法做出选择，B项对上段做出总结。故选B。3．C　该空后一句提到我们大多喜欢新事物超过旧事物，好奇心驱使我们探索未知，C项引出下文，与此相符。故选C。4．A　根据该空前一句提到要认为你现在的工作是最好的选择可知，我们要着眼于眼前，A项承接上文，符合语境。故选A。5．E　根据该空前两句提到要知道不论你身在哪边，另一边的草坪都是更绿的，E项据此提出最后一个解决办法。故选E。Ⅲ.语法填空(2019·山东师范大学附中高三第二次模拟考试)The life and work of Marie CurieMarie Curie is probably the most famous woman scientist __1__ has ever lived.

It was said to be 6－10 feet tall, weighing over 500 pounds and was covered in brown or red fur with large eyes and a big head. Footprints up to 24 inches long have been found.Teams of scientists and researchers who have gone there to do research have found things related to it, such as waste, fur and so on. However, so far there has been no other evidence to prove its existence. Some people think it may be just folk tales or stories to terrify hikers and hunters in North America.
