Poetry is the artistic expression of the human thoughts and feelings in rhythmical and emotional language． Compared with prose （散文） ， it lays more stress on rhythm， imagery （意象）， emotion， and imagination． As its language is rhythmical， its sound is highly musical． We may say， "No rhythm， no poetry"， no matter the rhythm of poetry is traditional as in metrical （格律的） style or "natural" as in free verse．
So the poet must write carefully and reflectively in order to find words that not only fulfills the demands of meter and rhyme， but also expresses the meaning in a manner that complements the imagery and tone of the rest of the poem． This careful use of language is the most significant difference between ordinary prose and poetry．
The ordinary prose writer neatly builds an argument using words the way a mason （石匠）builds a house using bricks； the poet is an artisan who creates a fieldstone hearth （大卵石壁炉炉床）- each stone or each word is turned over， examined， and often laid aside until it can be placed where its shape， weight， and color will contribute to the strength and beauty of the whole． Prose， according to Samuel Taylor Coleridge， is "words in their best order"， and poetry is "the best words in their best order"．
The reader's chief delight in reading poetry comes from his response to its musical effect， which comes from many metrical patterns represented in conventional iambic （抑扬格） feet or from repetitions and parallel phrasing shown in free verse and from other elements of poetry．



What's the purpose of saying "No rhythm， no poetry" in paragraph 1？ ______

A. To show the importance of rhythm in poetry．
B. To show rhythm is the most important element．
C. To show there is no limit on the use of rhythm．

A Russian spacecraft traveling to the International Space Station Thursday had to make an emergency landing when a rocket engine failed to fire． It was the latest in a recent series of failures for the Russian space program， which is also used by the U．S． to carry its astronauts to the station．
United States astronaut Nick Hague and Russian astronaut Alexei Ovchinin landed safely about 20 kilometers from Dzhezkazgan in Kazakhstan． The city is about 450 kilometers from the Russia's Baikonur space center， which Russia operates through an agreement with the Republic of Kazakhstan．
Both the U．S． space agency NASA and Russia's Roscosmos reported that the two were quickly recovered from the landing area by rescue crews． A spokesman for Russian President Vladimir Putin said， "Thank God the crew is alive" after they had landed safely．
About two minutes after launching， the three-stage Soyuz booster rocket suffered an unspecified failure of its second stage． Russia's TASS news agency said the capsule carrying the two men separated from the troubled rocket safely． This caused the capsule to drop very sharply into the Earth's atmosphere． Parachutes（降落伞）helped slow the returning capsule． Search and rescue teams were sent to recover the crew．
Russia's RIA news agency reported that Russia has immediately put off all manned space launches after the failure． Roscosmos head Dmitry Rogozin said he had ordered a state commission to carry out an investigation into what went wrong． He said Russia will share all relevant information with the U．S．
The TASS news agency said that the ISS crew has enough supplies and that the failed launch will not affect operations．
The U．S． and other nations have depended on Russia to carry astronauts to the ISS since the retirement of the Space Shuttle program in 2011． In coming years， American aerospace companies SpaceX， with its Dragon 2， and Boeing， with its Starliner， are expected to return to space．

If you feel sick or uncomfortable， you might seek out a doctor． But what to do if you don't quite know where you fit into this world and you're tired of carrying that burden alone？
I answered strangers" questions on life puzzles at the entrance to the New York City subway at 57 th and 8th． A group of strangers had stopped by because they were carrying around some deep， meaningful questions that had long gone unanswered， like "why can't I be happier in my life？"
And then I spotted her， who would be my toughest questioner of the day． She was about 6 years old and held her mother's hand as she craned（伸长脖子）her neck to stare at as． Her mother stopped， but the girl hesitated． "It's OK，" I offered． "Do you have a question？" The girl smiled at her mother， then let go of her hand to walk over towards us． She looked me dead in the eye and said： "How do I know I'm real？"
Suddenly I was back in graduate school． Should I talk about the French philosopher Rene Descartes to prove our existence， with the phrase "I think， therefore I am？" Or， menlion English philosopher G．
Moore and his famous uhere is one hand， here is the other，" to prove the existence of the external world？ But then the answer came to me． I remembered that the most important part of philosophy was feeding our sense of wonder． "Close your eyes， I said． She did． "Well，did you disappear？" She smiled and shook her head， then opened her eyes． "Congratulations， you're real． "
She grinned（露齿而笑）broadly and walked over to her mother， who looked back at us and smiled．

These days everyone is worried about the size of their carbon footprint． In order to reduce global warming， we need to make our carbon footprints smaller． But how much CO are we responsible for？
A new book by Mike Berners-Lee （a leading expert in carbon foot-printing） might be able to help． The Carbon Foot print of Everything looks at the different things we do and buy， and calculates the amount of CO₂ they produce， including the ingredients， the electricity， the equipment， the transport and the packaging． And it's frightening how much carbon dioxide everything produces．
But all of this can help us decide which beer to drink． From Berners-Lee's calculations， it's clear that a pint （568 ml） of locally-brewed （酿制的） beer has a smaller carbon footprint than a bottle of imported beer． This is because the imported beer has been transported from far away， and it uses more packaging． The local beer only produces 300 g of CO₂-but the imported beer produces 900 g! So， one pint of local beer is better for the environment than three cans of cheap foreign beer from the supermarket．
Berners-Lee has even calculated the carbon footprint of cycling to work． Nothing is more environmentally - friendly than riding a bike， surely？ Well， it depends on what you've had to eat before． To ride a bike we need energy and for energy we need food． So， if we eat a banana and then ride a kilometer and a half， our footprint is 65 g of CO₂． However， if we eat bacon before the bike ride， it's 200g． In fact， bananas are good in general because they don't need packaging． They can be transported by boat and they grow in natural sunlight．
So， does this mean that cycling is bad for the environment？ Absolutely not． If you cycle， you don t use your car； and the fewer cars on the road， the fewer traffic jams． And cars in traffic jams produce three times more CO₂ than cars travelling at speed． Cycling also makes you healthy and less likely to go to a hospital． And hospitals have very big carbon footprints!
So， maybe it's time for us all to start making some changes． Pass me a banana and a pint of local beer， please．



Which of the followings produces the smallest carbon footprints？ ______

A. A pint of local beer．
B. A bottle of imported beer．
C. A banana before a 1.5 km bike ride．
D. Bacon before a 1.5 km bike ride．

According to the article， the author suggests choosing the local food because it is ______ ．

A. more tasty
B. easier to buy
C. better packaged
D. more energy-saving

The purpose of writing this article is to ______ ．

A. promote a new book
B. advertise the imported beer
C. instruct how to measure the carbon footprint
D. encourage people to reduce the production of CO₂

Shark attacks not only disturb beach activities， but can affect associated tourist industries． Shark nets are a common solution to preventing shark attacks on beaches， but they cause dangers to sea ecosystems．
Seeking a cost-effective way to monitor beach safety over large areas， we have developed a system called Shark Spotter． It combines artificial intelligence （AI）， computing power， and drone （无人机） technology to identify and warn lifesavers to sharks near swimmers． The project is a cooperation between the University of Technology Sydney and The Ripper Group， which is pioneering the use of drones-called "Westpac Little Ripper Lifesavers"-in the search and rescue movement in Australia．
SharkSpotter can detect sharks and other potential threats using real-time aerial imagery． The system analyses video from a camera attached to a drone to monitor beaches for sharks， send warnings， and conduct rescues． Developed with techniques known as "deep learning"， the Shark Spotter system receives imagery from the drone camera and attempts to identify all objects in the scene． Once certain objects are detected， they are put into one of 16 categories： shark， whale， dolphin， rays， different types of boats， surfers， and swimmers．
If a shark is detected， Shark Spotter provides both a visual sign on the computer screen and an audible warning to the operator． The operator confirms the warning and sends text messages from the Shark Spotter system to the Surf Life Savers for further action． In an emergency， the drone is equipped with a lifesaving flotation pod （漂浮仓） together with an electronic shark repellent （驱逐装置） that can be dropped into the water in cases where swimmers are in severe trouble， trapped in a rip， or if there are sharks close by．
In January 2018， the Westpac Little Ripper Lifesavers was used to rescue two young swimmers caught in a rip at Lennox Head， NSW． The drone flew down the beach some 800 meters from the lifeguard station， and a lifesaving flotation pod was dropped from the drone． The complete rescue operation took 70 seconds．
We believe Shark Spotter is a win-win for both marine life and beachgoers． This unique technology combines dynamic video image processing AI and advanced drone technology to creatively deal with the global challenge of ensuring safe beaches， protecting environments， and promoting tourism．



A Shark Spotter is ______ ．

A. a solution to monitor sharks

You have probably heard of the Mozart effect． It's the idea that if children or even babies listen to music composed by Mozart， they will become more intelligent． A quick Internet search reveals plenty of products to assist you in the task． Whatever your age is there are CDs and books to help you taste the power of Mozart's music， but when it comes to scientific evidence that it can make you more clever， the picture is more mixed．
The phrase "the Mozart effect" was made up in 1991， but it was a study described two years later in the journal Nature that sparked real media and public interest about the idea that listening to classical music somehow improves the brain． It is one of those ideas that sound reasonable． Mozart was undoubtedly a genius himself； his music is complex and there is a hope that if we listen to enough of it， we'll become more intelligent．
The idea took off，with thousands of parents playing Mozart to their children， and in 1998 Zell Miller， the Governor of the state of Georgia in the US， even asked for money to be set aside in the state budget so that every newborn baby could be sent a CD of classical music． It was not just babies and children who were exposed to Mozart's music on purpose， even an Italian farmer proudly explained that the cows were played Mozart three times a day to help them produce better milk．
I'll leave the debate on the impact on milk yield to farmers， but what about the evidence that listening to Mozart makes people more intelligent？ More research was carried out but an analysis of sixteen different studies confirmed that listening to music does lead to a temporary improvement in the ability to handle shapes mentally， but the benefits are short-lived and it doesn't make us more intelligent．



What can we learn from Paragraph 1？ ______

A. Mozart composed many musical pieces for children．
B. Children listening to Mozart will be more intelligent．
C. There are few products on the Internet about Mozart's music．
D. There is little scientific evidence to support the Mozart effect．

Why did many people believe in the idea of the Mozart effect？ ______

A. Because a study described it in the journal Nature．
B. Because Mozart himself was a genius．
C. Because Mozart's music is enjoyable．
D. Because Mozart's music makes people relaxed．

The underlined sentence in Paragraph 3 suggests that ______ ．

A. people were strongly against the idea
B. the idea was accepted by many people
C. Mozart played an important part in people's life
D. the US government helped promote the idea

What is the author's attitude towards the Mozart effect？ ______

A. Favorable．
B. Objective．
C. Doubtful．
D. Positive．

One day your pocket might power your smartphone． Soon you may never have to worry about your smartphone running out of juice． Your clothing will simply power it back up for you． That's the word from scientists at China's Chongqing and Jinan Universities in a study just published in the journal ACS Nano．
Researchers have been hard at work during the last few years trying to create wearable energy， or clothes that can charge things． The assumption is simple． People today rely heavily upon devices such as smartphones and tablets． And they're looking for ways to recharge these devices on the go． So if you could design clothing fabric that could make use of solar power -one of the most widely available and inexhaustible renewable energy sources - you'd be able to charge your various devices with ease．
Scientists have had some past success creating energy-harvesting fibers． But there was always one problem when they tried to fashion these threads into self-powered smart clothes： The fibers they designed got damaged during the clothing manufacturing process， namely during the weaving and cutting． The Chongqing and Jinan University scientists say they've solved this problem because the energy-collecting and energy-storing threads they created are highly flexible - each individual thread is easily bendable， and not simply the fabric as a whole．
The team's sample textile can be fully charged to 1.2 volts in 17 seconds by exposure to sunlight - enough voltage that your future smart T-shirt or smart dress might be able to power small electronics． It's durable， too； their research showed there was no descent in the fabric after 60 days． But don't worry that this means the fabric is similar to rough cloth． The scientists note their textile can be fashioned into numerous different patterns， and tailored into any designed shape， without affecting performance．

"Make way， good people， make way， in the King's name! "cried he． "Open a text； and， I promise you， Mistress Prynne shall be set where man， woman， and child， may have a fair sight of her brave clothing， from this time till an hour past noon． A blessing on the moral Colony of the Massachusetts， where immorality is dragged out into the sunshine! Come along， Madam Hester， and show your scarlet （鲜红色的；罪孽深重的）letter in the market-place!
A lane was at once opened through the crowd． Led by the beadle （狱吏），and attended by an irregular procession of serious-looking men and unkind-looking women， Hester Prynne set forth towards the place appointed for her punishment． A crowd of eager and curious schoolboys， understanding little of the matter in hand， except that it gave them a half-holiday， ran before her progress， turning their heads continually to stare into her face， and at the winking baby in her arms， and at the shameful letter on her breast．
It was no great distance， in those days， from the prison-door to the market-place． Measured by the prisoner's experience， however， it might be considered to be a rather long journey； for， though her manner was proud， she perhaps underwent an extreme pain from every footstep of those who thronged to see her， as if her heart had been thrown into the street for them all to step upon． In our nature， however， there is a condition that the sufferer should never know the intensity of what he endures by its present suffering， but chiefly by the pain that rankles （使痛心）after it． With almost a calm manner， therefore， Hester Prynne passed through this portion of her suffering， and came to a sort of scaffold （刑台），at the western end of the market-place． It stood nearly beneath the eaves of Boston's earliest church， and appeared to be a fixture there．



What can we know about the schoolboys？ ______

A. They knew a little of the matter．
B. They were full of curiosity and eagerness．
C. They were happy for having a one-day holiday．
D. They like Hester Prynne and her baby very much．

In areas like the Central United States that get lots of tornadoes， there′s a common piece of celestial （天上的）fortune-telling that green skies mean a tornado is on its way． Research has shown that it isn′t quite as simple as that， but scientists have found that if you see a green sky， you should probably go inside． As far as most scientists can tell， the green skies around powerful thunderstorms are usually a combination of red sunsets and water droplets．
Daytime skies are blue because blue shorter wavelengths of visible light tend to bounce off （反 射）air molecules better than red longer wavelength light． So the blue light gets bounced all over the sky and looks like it's coming from everywhere． Meanwhile， around sunset sunlight travels through so much atmosphere that just about all the blue is bounced away from the horizon， leaving all those reds and oranges behind． The sunset might look exclusively （独有的）red and orange， but there's still some green and even blue light hidden in there， just far less than the other colors． But for us to notice the remaining green light， it needs to hit something that reflects green light much better than red． That's where water comes in．
Big tall threatening storm clouds are made of water droplets， and even though water is best at reflecting blue light， it can still reflect green pretty well， much better than reds and oranges， so under just the right conditions， the water in and around a cloud can bounce the green light hidden in the sunset right into our eyes making the sky look green．
Still， none of the conditions that can turn skies green are unique to the clouds that produce tornadoes． Sometimes they just lead to lots of rain， and maybe some hail． So if you see huge storm clouds rolling in and a green tint （色调）in the sky， it doesn't necessarily mean there′s about to be a tornado， but it does mean you should probably head indoors．



What can be the best title for the text？ ______

A. Why Do the Central United States Get Tornadoes
B. Do Green Skies Mean a Coming Tornado
C. A Common Piece of Celestial Fortune-telling
D. Green Skies Are Unique to Clouds
