高中英语人教版选修六Unit 5 The power of nature同步练习

阅读理解。

    Tornadoes are nature's most violent storms, which can cause deaths and destroy a neighborhood in seconds. A tornado appears as a funnel-shaped (漏斗状) cloud from a thunderstorm to the ground with whirling (飞快移动) winds that can reach 300 miles per hour. Damage paths can be over one mile wide and 50 miles long. Every state is at some risk from this disaster.

    Some tornadoes can be seen clearly, while rain or nearby low-hanging clouds obscure others. At many times, tornadoes develop so rapidly that little, if any, advance warning is possible.

    Before a tornado hits, the air may become very still. A cloud of debris (散片) can mark the location of a tornado even if a funnel can not be seen. Tornadoes generally occur near the edge of a thunderstorm, when the strong wind may die down. It is not uncommon to see clear, sunlit skies behind a tornado.

The following are facts about tornadoes:

    The average forward speed of a tornado is 30 MPH, but may also vary from still to 70 MPH. Debris is picked up or a cloud forms in the funnel.

    The average tornado moves from southwest to northeast, but tornadoes have been known to move in any direction. Tornadoes are most often reported east of the Rocky Mountains during spring and summer months.

    Tornadoes can happen together with tropical storms and hurricanes as they move onto land. Waterspouts are tornadoes that form over water.

    The tornado season in the southern states of America is March through May; in the northern states, it is late spring through early summer. Tornadoes are most likely to occur between 3 p.m. and 9 p.m., but can occur at any time.

(1)、From the passage, where may tornadoes come from?
A、Hurricanes. B、Great heat. C、Thunderstorms. D、Sandstorms.
(2)、What does the underlined word “obscure” probably mean?
A、Hide. B、Reduce. C、Produce. D、Raise.
(3)、When a tornado happens, ________.
A、it often reaches the speed of 70 MPH B、it can only be seen in the late of the day C、it may form on the surface of sea water D、it only moves from southwest to northeast
(4)、The passage makes us believe that ________.
A、tornadoes are mostly seen in the southern states of America B、warnings about tornadoes are well developed in many countries C、of all the natural disasters, tornadoes often cause the biggest damage D、tornadoes may strike so quickly that there is often little or no warning

    Students taking Georgia Tech's online Knowledge-Based Artificial Intelligence course received some surprising news. Jill Watson one of the nine teaching assistants(TAs) that had helped them finish the challenging course for the past five months was not a ‘‘she'' but an “it”—an intelligent robot!

    Watson is the brainchild of Ashok Goel, who teaches the popular online course. The Professor-of Computer and Cognitive Science in the School of Interactive Computing came up with the idea as a way to deal with a number of questions posed by students in the online forums(论坛). According to Goel, every time the course is offered, the 300 or so students that enroll post over 10,000 questions which are often repetitive. This led Goel to wonder if a smart robot would handle the questions which require standard responses.

    Having worked' with IBM's Watson technology platform in the, the professor knew it would be ideal for his artificial TA: Jill Watson. The artificial intelligence system that uses natural language processing and machine learning to analyze large amounts of data has even been cleverer than human competitors on the television show. It would therefore easily be able to handle routine questions that required little “thinking”.

    The professor and his team of graduate students began by populating Jill's memory with 40,000 questions and answers from past terms. Then came the testing stage. At first, Jill was not very good and often gave strange answers. It often got stuck on certain keywords. By the end of the semester, Jill had attained enough knowledge and skills to participate in forums without any management from Goel, or the other assistants.

    Apple announced its new iPhones last week, but competitors' mobile phones can do many of the same things for less money.

    The new iPhone 8 and X have wireless charging, edge-to-edge glass screen and double cameras. But all of these features are already available in smart phones from China's Huawei and Oppo, and Korea's Samsung. While Apple asks buyers to pay $1,000 for its high-end model, some Asian phone makers can offer similar features for less.

    At one time, Chinese manufacturers copied features and designs from others to produce low-cost phones. But they have now added high-end features to their phones and they control nearly half the global mobile phone market.

    Media MarktSaturn is Europe's biggest electronics seller. A spokesperson for the store told Reuters that,“Huawei is seen as a relevant competitor to Apple and Samsung by covering all major price points and placing big investments in marketing and sales. '' She also said that the Chinese companies Huawei, ZTE, Lenovo and TCL were among the top-10 best-selling smart phones in its stores.

    Chinese manufacturers' fast growth has been fueled by strong sales in China. But they now export 40 percent of their smart phones. That is almost double the number from just three years ago, according to the Hong Kong investment company CLSA.

    Huawei is currently the world's third largest phone maker behind Samsung and Apple. According to research company Canalys, the Chinese company is getting closer to second-place Apple and might overtake it later this year.The Chinese company even made fun of Apple's new facial recognition feature with a Facebook video called "Real AI phone." Huawei plans to show its top-of-the-line Mate 10 phone on Oct. 16. The phone will have artificial intelligence features such as instant translation and image recognition and will cost less than $1,000.    Other Chinese companies are looking to enter the high-end smart phone market.

    Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn't know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.

    But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many, many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.

    Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.

    Twenty –five years ago, there were hardly any education programs for environment. Today, it's hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” say Bruce Anderson.

    Charlie is a teacher and his wife, Maria is an artist. The night before last, just before the longest day of the year, Charlie was sitting in a deckchair enjoying the warm summer air when Maria touched his shoulder and he could tell immediately she was a little worried about something. He asked her what the matter was and she replied that there was a strange thing on the jacket that was hanging in the bedroom. They had both lived in the West Indies (西印度群岛) and had seen a lot of strange creatures in their house before. But now they were living in England and so Charlie just laughed and said he would have a look at the "thing".

    He walked to the bedroom. He saw a jacket hanging in the bedroom and went up to it to have a closer look at the "thing". The moment he touched it, the thing sprang into life. Now Charlie experiences fear like the rest of us but when this creature opened its wings, he jumped out of his skin and ran screaming from the room like a small child doing about 100 miles an hour.

    For a moment the next-door neighbours thought that Charlie was murdering his wife because of the noise they could hear. In fact, it was a bat that frightened Charlie.

    Eventually Charlie managed to trap the bat in a box and took it to the garden to let the bat fly. Maria, who had been playing the guitar while Charlie was upstairs, asked Charlie if he had found out what the thing was. "Oh, nothing to worry about", he said casually hoping that the terror could not be seen in his eyes, "it was just a bat."

    If you make a list of the top ten most challenging jobs in the world, chances are that being a teacher will not make the cut. Let's think about their complex task millions of educators face each day as they try to teach a group of often unfriendly, disorderly kids into intelligent, well-rounded individuals. That surely has to be the toughest job in the world, especially taking into consideration that there is no promotion waiting for them even if they are wildly successful!

    What if these all-important individuals that we often take for granted disappear from our lives? That was what Project Ed and Participant Media's teaching campaign asked filmmakers of all ages to envision for their recently-held contest.

    Their short films were called "A World without Teachers", whose intention was to inspire more young people to become teachers. However, the 62 amazing video submissions (提交物) also serve as a reminder of how terrible things would be if we didn't have these selfless individuals guiding us through life. What was interesting is that even the youngest contestants didn't accept the idea that there's no person to tell them what to do.

    High-school student Savannah Wakefield considered if art as we know today would have been different without teachers. Would C. Monet have discovered his talent for impressionism?

    Miles Horst won the 1,000-dollar prize for the best adult submission, lie pictures n world where teachers are replaced by a "brain box". Youth group winner Marina Barham's video describes a fact we all know but often forget. Teachers don't just teach; they inspire—something that no electronic device, no matter how smart, can do!

    So the next time you think your teacher is being "troublesome" for trying to channel you in the right direction, imagine a life without him/her.
