ADo you want to see majestic lions roaring, rare rhinos running and colorful birds flying？You'll find this incredible display of nature in the Kenya Lake System in the Great Rift Valley.First stopFly into Nairobi, the capital of Kenya. This great city is known for its fashion markets and beautiful art. And be sure to pick up some rich Kenyan coffee while you're there! Then head for the countryside.Plan your tripThe largest of the three lakes in the system, Lake Nakuru, is less than 175 kilometers fromNairobi. But Lakes Bogoria and Elementaita are equally worth a visit. You can stay at one of several choices of' luxurious cabins in the valley, And if you sign up for a trip, be sure to put flamingos, the white and pink birds, at the top of your list.ParadiseThe Kenya Lake System is shallow and alkaline(碱性的). That means it supports vegetation such as green algae, a food source for many waterfowl. Hundreds of species of birds flourish here, using this area as a major breeding and nesting ground. Water buffalo, leopards.monkeys and the endangered Rothschild giraffe also make this area their home.Other sightsWildlife isn't the only natural wonder in the Great Rift Valley. The valley marks a place where the earth is divided far below the surface. This rock separation below ground leads to noticeable features above ground, Walking around Lake Bogoria especially, you will see steam rising from hot springs.Other activities include golfing, horseback riding and hiking. The fun doesn't stop when the sun goes down, either. The river valley is far from city lights, so many visitors gaze at the stars shining above.If you are ready for a wildlife experience, don't hesitate!21.W hat is Nairobi famous for？A.Coffee markets.B. Beautiful fashion shows.C.Fashion markets.D. Great artists.22. Which does the passage recommend visitors to see first in the Kenya Lake System?A. Majestic lions.B. Rare rhinos.C.Colorful flamingos.D.Luxurious cabins.23.What can visitors do in the Great Rift Valley?A. Horseback riding and hiking.B. Shopping for fashionable clothesC.Admiring beautiful artworks. D, Enjoying Kenyan coffee.BJack Prelutsky is an American poet, He is known for his humorous and fantastic poetry forchildren,which has earned him numerous awards.Jack Prelutsky was born in Brooklyn, New York in 1940. As a child, he did not enjoy poetry, finding it boring and pointless. instead, Prelutsky expressed his artistry through music.taking voice and piano lessons. While Prelutsky claims he got into poetry almost by accident, he also states that he was always a poet. It just took him some time to realize his love for poetry.Prelutsky explored quite a few options before he found his niche in poetry. He was a folksinger and guitar teacher in Greenwich Village in his late teens and early twenties, Prelutsky also held a variety of odd jobs, He worked as a furniture mover, piano mover, taxicab drivercoal shoveler, fruit picker, truck driver and photographer, among other jobs.At the age of23,Prelutsky decided to try illustrating. Just before presenting his illustrations to a children's book editor, he added a few lines of poetry to the pictures. The editor told him that the illustrations were not publishable but the poems showed the talent. Over the next months and years, Prelutsky worked with the editor to create a collection of animal poems inspired by his love of the Bronx Zoo. His first book, entitled A Gopher in the Garden and Other Animal Poems, was published in 1967.In addition to writing, Prelutsky has edited various poetry collections and translated poetry from German and Swedish into English. He currently resides in Seattle, where he writes and performs his work, Prelutsky is considered one of the most popular children's poets. His work pioneered a new era of' children's poetry, In 2006, the Poetry Foundation named Jack Prelutsky the first Children's Poet Laureate, a position designed to promote poetry for children and raise awareness of the power and relevance of poetry for young people.24.Why did Prelutskv dislike poetry in his early years?A. It was too difficult.B. He wasn't good at it.C. He thought it meaningless.D. It took up too much of his time.25, Which of`the following can replace the underlined word “niche" in paragraph 3?A. Mistake.B.Dream.prehension.D.Interest.26. How old was Prelutsky when he published his first book?A.23.B.27.C.40.D.66.27. What is the purpose of the text?A. To introduce a poet.B. To attract poetry lovers.C.To display some excellent poems.D. To encourage readers to write poems.CA popular saying goes, “Sticks and stones may break my bones, but words will never hurt me." However, that's not really true. Words have the power to build us up or tear us down. L doesn't matter if the words come from someone else or ourselves -- the positive and negative effects are just as lasting.We all talk to ourselves sometimes. We're usually too ashamed to admit it, though. In fact we really shouldn’t be because more and more experts believe talking to ourselves out loud is a healthy habit.This “self-talk" helps us motivate ourselves, remember things, solve problems, and calm ourselves down. Be aware, though, that as much as 77% of self-talk tends to be negative. So in order to stay positive, we should only speak words of encouragement to ourselves. We should also be quick to give ourselves a pat on the back. The next time you finish a project, do well in atest, or finally clean your room, join me in saying “Good job!"Often, words come out of our mouths without us thinking about the effect they will have. But we should be aware that our words cause certain responses in others. For example, where returning an item to a store, we might use warm, friendly language during the exchange. And the clerk will probably answer in a similar manner. Or harsh(刻薄的) and critical language will most likely cause the clerk to be defensive.Words have power because of their lasting effect. Many of us regret something we once said. And we remember unkind words said to us! Before speaking, we should always ask ourselves: ls it loving? ls it needed? If what we want to say doesn't pass this test, then it's better left unsaid.Words possess power: both positive and negative. Those around us receive encouragement when we speak positively. We can offer hope, build self-esteem(自尊) and motivate others to do their best. Negative words destroy all those things. Will we use our words to hurt or to heal?The choice is ours.28. The main idea of the first paragraph is that .A.words have a great effect on usB.encouraging words give us confidenceC.not sticks and stones but words' will hurt usD.negative words may let us down29. There is no need for us to feel ashamed when we talk to ourselves because .A.almost everybody has the habit of talking to themselves.B. it does no harm to have “self-talk" when we are alone.C.talking to ourselves always gives us courage.D,talking to ourselves can have a positive effect on us.30. The underlined part in the third paragraph means that we should also timely .A.remind ourselvesB. praise ourselvesC.make ourselves relaxedD. give ourselves happiness31. The author would probably hold the view that .A. it is better to think twice before talking to othersB. negative words may stimulate us to make more progressC. people tend to remember friendly wordsD. encouraging words are sure to lead to kind offersDWHY SHENNONGJA?As we know, in 2016, Shennongjia made it on to the UNESCO World Heritage List. But there are so many important places not vet on this list. So you might ask: why Shennongjia?UNESCO awarded Shennongjia this status because it meets two criteria required by the list It contains a naturally-balanced environment that allows the many and various species to live and prosper. It is also one of the rare locations in the world where scientists can observe in real time the ecological and biological processes that occur as the plants and animals develop and evolve.For the first criterion, Shennongjia is apparently one of the most "complete" natural areasin the world. The region rises from about 400 metres to over 3, 000 metres above sea level giving it the name the "Roof of Central China"For the second criterion, we can see that Shennongjia has incredible biodiversity. Look at this slide. According to official statistics, over 3, 000 plant species have been recorded there This represents more than ten percent of China's total floral richness .It is a challenge to look after so many species. In winter, scientists brave heavy snow and freezing temperatures to supply food to the Golden Snub-nosed Monkey, Thanks to their efforts the monkey's population has doubled since the 1980s.Their number reached over 1. 300 in 201$and continues to grow.But the most impressive aspect of Shennongjia is the local people, who take things from nature without causing damage. I visited a local village which is known for its home-made honey. What is special about the honey is that it is produced by the earliest species of Chinese bee.

One New Jersey man has proved that to be true by achieving a lifelong goal more than 80 years in the making. Earlier in March, a101-year-old man named Merrill Pittman Cooper received his high school diploma during a graduation ceremony in his honor.Cooper attended Storer College from 1934 to 1938, but life circumstances got in the way and prevented him from finishing school and earning his diploma. Without his father around, it was up to him and his mother to take care of themselves. His mom had taken on work as a live-in housekeep er in order to pay his school tuition and board, but that wasn't enough. And after realizing his mother couldn't afford to make the final tuition payment for his senior year, the teen encouraged her to move them to Philadelphia.In Philadelphia, Cooper took on work to help his mother pay the bills. He was hired as a city trolley car operator in 1945. That job led him to a long and fruitful career in transportation where he became president of the local union and later vice president of the International Transport Workers Union in New York City. But despite such a successful career, he always regretted not getting his high school diploma and struggled to finish all he should learn.But now, after 84 years, Cooper was able to see his lifelong dream come true. His family got the idea to surprise him with the honorary high school diploma. Cooper could hardly hold back his tears when he discovered their plan after arriving at the hotel.The whole thing was a dream come true for Cooper, who now displays his framed diploma proudly. “I can't think of a happier day,” says the inspiring 101-year-old man. “I'm really happy to finally have it.”4．What stopped Cooper from getting his high school diploma when he was young?A．Poverty.B．Illness.C．Laziness.D．War.5．What can we learn from Paragraph 3?A．Cooper changed his work frequently.B．Cooper first worked as a car driver.C．Cooper was a great success in his career.D．Cooper quit studying after getting a job. 6．How did Cooper feel after getting the diploma?A．Confused.B．Regretful.C．Relieved.D．Proud. 7．What can be concluded from the text?A．Practice makes perfect.B．A bird in the hand is worth two in the bush.C．It's never too late to go after your dreams.D．A friend in need is a friend indeed.Have you ever noticed that some songs start with a “one, two, three, four”? You can hear it in songs by artists as different as The Beatles, OutKast, and Taylor Swift. But why are they counting? The counting you hear is a small clue to a big fact—math is behind almost everything in music! Let’s WONDER together!First, let’s start with “counting in.” Musicians will often count to make sure that they all start the song at the same time. Once they start together, everyone has to stay on the same beat. Every song has a steady beat. One of the first ways that young children can start to learn math ideas is by learning how to make a steady beat!A steady beat is one kind of pattern. Other patterns in music relate to math, too. We can see patterns in how far apart notes are from each other. Sometimes we play more than one note at a time.Musicians also need numbers to understand how to play music. If you look at written music, you will see two numbers on the left side. Often, the numbers are 4/4. This is called the time signature. The top number of it tells the musician how many beats are in each part of the line of music. The second number tells us what type of note gets one beat. The “4” on the bottom lets us know that a quarter note gets one beat.It is clear that music is good for our brains, whether or not it makes us better at math. Playing music uses several parts of your brain at the same time. Musicians need to use their brains to see the music, hear the notes, and touch the instrument in just the right ways to make sounds!These are just a few of the ways that music and math are related. As you learn more about music and math, you'll see more connections!8．What is the purpose of the first paragraph?A．To give examples.B．To introduce the main topic.C．To present an academic achievement.D．To list the impact of some famousmusicians.9．What does the second number of the time signature mean?A．What category of note gets one beat.B．What varieties songs should have.C．How many beats are in each measure.D．How the former note is transformed into the next.10．How does the author like learning music?A．Dizzy but powerful B．Complicated but rewarding.C．Time-consuming but relaxing.D．Expensive but pleasant.11．What can be inferred from the text?A．To learn math well, you have no choice but to have a good command of music.B．The performance of one’s music may have an effect on that of one's math.C．The more you learn music, the more broad-minded you will be.D．People’s taste in music varies from person to person.Mahadevan, the Lola England de Valpine Professor of Applied Mathematic s at the Harvard John A．Paulson School of Engineering and Applied Sciences(SEAS), and his team combined physics and machine learning to develop a new 3D-printing technique that can quickly create complex physical patterns including making an exact copy of a Pollock painting by controlling the same natural fluid instability that Pollock used in his work.The issue, as it usually is, is physics. Liquid inks are bound by the rules of fluid dynamics, which means when they fall from a height, they become unstable, folding and coiling(螺旋) in on themselves.Today, most 3D and 4D printing techniques place the print nozzle(喷嘴) near the surface, eliminating the dynamic instability of the liquid stream.But Mahadevan has a motto: use the physics, instead of avoiding it. Pollock composed his famous drip(滴) paintings by placing a canvas on the floor and pouring, dripping paint onto it from above. To the untrained eye, his technique may seem random, but Pollock always claimed he had complete control over the flow of the paint.“If you look at traditional 3D printers, you supply them a path from point A to point B and the nozzle deposits ink along that specified path,” said Chaudhary.“But Pollock’sapproach of throwing paint from a height meant that even if his hand was moving in a specific track, the paint didn't follow that track because of the acceleration gained from gravity.”“With deep learning, the model can learn from its mistakes and get more and more accurate with each trial,” said Chaudhary. The researchers used simple fluid s for this research, but the approach could be expanded to include more complex fluids.As the research continues, there is no telling where Mahadevan may look for inspiration next. “When you're in Maha's lab, nothing is off the table,” said Chaudhary.12．Why is Pollocko's painting mentioned?A．To show his incredible skills.B．To highlight his commitment to art.C．To illustrate the impact of the new technique.D．To compare his painting and the new 3D-printing.13．What can replace the underlined word “eliminating” in paragraph 3?A．Measuring.B．Removing.C．Perceiving.D．Overestimating. 14．What can be concluded from Chaudhary's words in the last paragraph?A．Nothing may be impossible for Mahadevan.B．Nothing can be the inspiration for him.C．He disapproves of Maha's research.D．Mah a pioneers in the research lab. 15．What can be the best title of the text?A．A Development in Complex Painting B．Physics Combined with MachineLearningC．Challenges Faced by Traditional 3D Printers D．A New 3D Printing TechniqueA Rain GardenA garden can be a place for family recreation or well-being of us, but the monsoons (季风) can turn your backyard into a grassy spot. 16 .Don’t drive away slimy pests. The rains also bring with them a flock of visitors, such as snails and ants. Before you lace your garden with insecticide, keep this in mind: Many of these pests are harmless and will do your green space a lot of good. For instance, snails can speed up the process of turning bío-degradable waste into fertilizer. 17 .Make use of rain water. Rainwater is the best kind of water for your plants. It’s as simpleas placing indoor pots on the balcony. You could also put out industrial drums and pots under the rain to load up on water for your garden. 18 . If you have the space, consider creating your own rain garden. Rain gardens collect run-off water from paved surfaces, thus saving you the additional effort of watering your plants.Weed it out. 19 . Besides, they rob your garden of the nutrients required to keep it flourishing. You can get rid of them naturally by pulling them out from the root. For deep-rooted weeds, make use of weeding knives and other tools to remove them.20 . This is the season to plant beauties such as jasmine, bird of paradise and Mountain Roscoe Lily. It’s also the time to cut out unnecessary branches of the plants such as ornamental asparagus... to reduce the burden on the plant. You can pot these shoots to get new plants too.A．Plant and cutB．Protect the new plantsC．Weeds typically crop up after a heavy rainfallD．These tips help you make the most of this seasonE．If you must rid your garden of them, go the chemical-free wayF．Read on for more reasons to have and build an appealing gardenG．Keep them covered with a lid when it’s not pouring, to avoid mosquitoes二、完形填空When you think of the strong actor and politician Arnold Schwarzenegger, what comeswrong 32 that we can do it all alone. In reality, none of us can 33 it.” Schwarzenegger’s message 34 beyond his personal story. He encouraged the audience to reflect on the people who have 35 us in our lives and to pay it forward by offering 36 and assistance to others whenever it is possible.In a society that often 37 individual achievement above all else, Arnold Schwarzenegger’s speech is a 38 reminder that we are interconnected.
