Yet compared to foreign counterparts, Chinese animation still has a long way to go. Here are four new popular series made in China.Lingjian MountainAnimation series Lingjian Mountain was adapted from an online Chinese novel of the same name. The series tell the story of a boy named Wang Lu and his adventures on his way to be a powerful prince. Bearing a strong resemblance to Japanese animation, the series was adapted by two companies from China and Japan and was also broadcast in both countries.

The author tells the contemporary Chinese history through a group of cute rabbits in uniforms who symbolize the People’s Liberation Army, and images of other animals. Sometimes, these animals would talk with a dialect that sounds funnier than simply using Mandarin. The series got 8．5points out of 10on Douban.Little Monk YichanThis is another touching about a seven-year old monk Yichan, and his master Adou’s daily lives. P remiered in 2016, the series had its episode 35broadcast recently. Each episode focuses on a certain topic, including family, romance and friendship.

The animation got 9．5points out of 10on Douban.Hua Jiang HuPremiered in 2014, the series has had four seasons. The story is based on Chinese history during the Five Dynasties and Ten Kingdoms (907-960), when there were continuous wars and fights among many small kingdoms. The series got an average of 7．9points out of 10on Douban. To those who fancy historical stories, the animation provides another way to learn Chinese hi story.

It may seem like an odd place to run a dance studio, but this church was disability accessible and that’s just what Tracey was looking for. Trace y needed a new home for her wheelchair dance students after the studio that was hosting the classes closed.Now Tracey has been teaching free dance classes to students in wheelchairs for over four years. This season, her class is made up of six boys and girls ranging in age from 6to 11who attend dance rehearsals(排练) twice a month. Tracey says these classes are about more than the dancing. “For any child to get out on stage is an accomplishment,” Tracey said. Tracey has always considered the students in her “Wonders on Wheels” class to be talented, but this week she got to share their talents with the world. On Sunday, the WOW class debuted(初次登台) a dance routine they’ve been working on since October.Last October, one week before the dance class reunited for a new season, one of the WOW children, Katie, passed away unexpectedly. Her teammates were heartbroken. They decided to honor their friend by giving this season’s dance to her. Everyone knew how much Katie loved Celine Dion, so the group chose the song My Heart Will Go On for the dance routine.The six WOW dancers, dressed in white, were surrounded by fourteen dancers dressed in black. These “shadows” are high school girls who volunteer to dance alongside the children in wheelchairs, helping them move across the dance floor. As the song came to an end, a huge round of applause erupted from the audience. 24．Why did Tracey build the dance studio in the church? _________A．It is free of charge.

But an ancient meteorite(陨石) found recently contains 10times more water and much more oxygen than any Martian I meteorite ever before discovered.What’s so wild about this wet discovery? It could mean that the Red Planet once had enough water to have I liquid flowing on the planet’s surface.It was once believed that if Mars ever had water at all, its water would have been small amounts of ice below the surface or existing in the soil only as hydrogen and oxygen—the elements that make up water. But recent discoveries have shown that Mars probably had a much wetter history than formerly thought.The meteorite, nicknamed Black Beauty, was found in Africa’s Sahara Desert in 2011．Only about 110meteorites from Mars have ever been found. Scientists believe most Martian meteorites arrived on our planet during one large asteroid crash(小行星碰撞) that sent rocks falling toward Earth long ago.Black Beauty is about 2．1billion years old. Its discovery is the first time scientists have been able to study such an ancient Martian rock. It’s also one of the first times scientists have been able to study a piece of the panel’s ancient surface.The sample’s water molecules were sent out when scientists heated the meteorite to analyze it. Scientists think the meteorite’s hydrogen and oxygen molecules are so plentiful because water flowing on Mars at the time this meteorite fell to Earth, or because these molecules were once sealed in large quantities in Mars’s crust.Black Beauty might do more than just unlock secrets from the Red Planet’s past. These discoveries could also h elp scientists understand new data about Mars that’s being sent from the robotic rovers currently gathering information on the planet.32．People used to think that _________A．there was little water on Mars B．Mars had a lot of flowing waterC．a large quantity of ice was Mars D．Mars was much wetter than Earth 33．What do we know about Black Beauty? _________A．It was discovered in Seattle in the USA．B．It is the biggest of 110meteorites from Mars. C．It landed on Earth after an asteroid crash. D．It has a history of 2．1million years. 34．How did the scientists research Black Beauty? _________A．By cutting it into pieces. B．By dipping it into water.C．By burning it on a fire. D．By burying it into a desert.35．The passage is mainly about _________A．A rock from the center of Mars. B．A major Martian meteorite discoveryC．A new discovery on the Red Planet D．A number of meteorites from Red Plane第二节(共5小题,每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项.For college graduates, it is of vital importance to write application letters well. 36 It should state clearly the job you want, and should tell what you have done. It should be simple, human, personal and brief without leaving out any necessary facts.In writing a letter of application, keep in mind that the things a possible employer is most likely to want to know about are your qualifications, your achievements and your aims. 37 If the first few sentences fail to win the reader’s attention, the rest of the letter ma y not be continued at all. Try to key your opening remarks to theneeds or interests of the employer not to your own needs or desires. For example, instead of beginning with “I saw your advertisement in today’s newspaper” you might say “I have made a caref ul study of your advertising during the past six months” or I have made a survey in my neighborhood to find out how many housewives use your product and why they like it.”38 Be clear about the kind of job for which you are now applying. College graduates looking for their first positions often ask what they can provide in a letter and what if employers warn experience, which, naturally, no beginner has. 39It is important to write a good strong closing for your letter. Make a specific request for an interview or give the possible employer something definite to do or expect. 40 That makes it easier for a possible employer to get in touch in you.A．Here are a few suggestions for you to prepare yourself better for your interview.B．An excellent idea is to enclose a stamped, self-addressed envelope with your letter.C．The answer is that everything you have ever done is experience.D．Don’t be afraid of being a new hand.E．Try to avoid writing in general.F．The purpose of a letter of application is to help you to “sell” yourself.G．The opening paragraph is perhaps the most import.第三部分英语知识运用(共两节,满分45分)第一节完形填空(共20小题;每小题1.5分,满分30分)阅读下面短文,从短文后各题所给的四个选项(A．B．C和D)中,选出可以填入空白处的最佳选项,并在答题卡上将该项涂黑.A few years ago I was working part time at a local ice cream shop.

Yet compared to foreign counterparts, Chinese animation still has a long way to go. Here are four new popular series made in China.Lingjian MountainAnimation series Lingjian Mountain was adapted from an online Chinese novel of the same name. The series tell the story of a boy named Wang Lu and his adventures on his way to be a powerful prince. Bearing a strong resemblance to Japanese animation, the series was adapted by two companies from China and Japan and was also broadcast in both countries. The animation series got 7．1 points out of 10 on Douban, one of China’s most popular movie review sites.Year Hare AffairThe series was adapted from namesake comic series by cartoonist Lin Chao. The author tells the contemporary Chinese history through a group of cute rabbits in uniforms who symbolize the People’s Liberation Army, and images of other animals. Sometimes, these animals would talk with a dialect that sounds funnier than simply using Mandarin. The series got 8．5points out of 10on Douban.Little Monk YichanThis is another touching about a seven-year old monk Yichan, and his master Adou’s daily lives. Premiered in 2016, the series had its episode 35broadcast recently. Each episode focuses on a certain topic, including family, romance and friendship. Despite telling stories from the perspective of a child, the series targets adults and aims to provide some “chicken soup” to let audiences learn to be tolerant and give more love to others. The animation got 9．5points out of 10on Douban.Hua Jiang HuPremiered in 2014, the series has had four seasons. The story is based on Chinese history during the Five Dynasties and Ten Kingdoms (907-960), when there were continuous wars and fights among many small kingdoms. The series got an average of 7．9points out of 10on Douban. To those who fancy historical stories, the animation provides another way to learn Chinese history. Yet the series doesn’t pay too much attention to historical details. 21．According to the text, which animation got the highest score? _________A．Lingjian Mountain. B．Little Monk Yichan.C．Hua Jiang Hu. D．Year Hare Affair.22．What does the underlined word “resemblance” probably mean? _________A．popularity. B．difference.C．similarity. D．Attraction.23．What can he learnt from the text? _________A．Recently Chinese animation has developed better than other countries.B．All series are not adaptations from novels online.C．People interested in ancient history prefer Year Hare Affair.D．Little Monk Yichan is intended for children.BTracey’s husband told her. “If you build it, they will com” So Tracey built a dance studio four years ago, and he was right.Tracey built Revere Dance Studio in an old large church in Cincinnati, Ohio. It may seem like an odd place to run a dance studio, but this church was disability accessible and that’s just what Tracey was looking for. Tracey needed a new home for her wheelchair dance students after the studio that was hosting the classes closed.Now Tracey has been teaching free dance classes to students in wheelchairs for over four years. This season, her class is made up of six boys and girls ranging in age from 6to 11who attend dance rehearsals(排练) twice a month. Tracey says these classes are about more than the dancing. “For any child to get out on stage is an accomplishment,” Tracey said. Tracey has always considered the students in her “Wonders on Wheels” class to be talented, but this week she got to share their talents with the world. On Sunday, the WOW class debuted(初次登台) a dance routine they’ve been working on since October.Last October, one week before the dance class reunited for a new season, one of the WOW children, Katie, passed away unexpectedly. Her teammates were heartbroken. They decided to honor their friend by giving this season’s dance to her. Everyone knew how much Katie loved Celine Dion, so the group chose the song My Heart Will Go On for the dance routine.The six WOW dancers, dressed in white, were surrounded by fourteen dancers dressed in black. These “shadows” are high school girls who volunteer to dance alongside the children in wheelchairs, helping them move across the dance floor. As the song came to an end, a huge round of applause erupted from the audience.24．Why did Tracey build the dance studio in the church? _________A．It is free of charge. B．It is near her home.C．It’s easy for the disabled to use. D．It is big enough to hold dancers.25．Tracey offered her dance class _________A．for free B．twice a weekC．only lo girls in wheelchairs D．with the help of volunteers26．What can best describe Tracey? _________A．Brave and determined.

But an ancient meteorite(陨石) found recently contains 10times more water and much more oxygen than any Martian I meteorite ever before discovered.What’s so wild about this wet discovery? It could mean that the Red Planet once had enough water to have I liquid flowing on the planet’s surface.It was once believed that if Mars ever had water at all, its water would have been small amounts of ice below the surface or existing in the soil only as hydrogen and oxygen—the elements that make up water. But recent discoveries have shown that Mars probably had a much wetter history than formerly thought.The meteorite, nicknamed Black Beauty, was found in Africa’s Sahara Desert in 2011．Only about 110meteorites from Mars have ever been found. Scientists believe most Martian meteorites arrived on our planet during one large asteroid crash(小行星碰撞) that sent rocks falling toward Earth long ago.Black Beauty is about 2．1billion years old. Its discovery is the first time scientists have been able to study such an ancient Martian rock. It’s also one of the first times scientists have been able to study a piece of the panel’s ancient surface.The sample’s water molecules were sent out when scientists heated the meteorite to analyze it. Scientists think the meteorite’s hydrogen and oxygen molecules are so plentiful because water flowing on Mars at the time this meteorite fell to Earth, or because these molecules were once sealed in large quantities in Mars’s crust.Black Beauty might do more than just unlock secrets from the Red Planet’s past. These discoveries could also help scientists understand new data about Mars that’s being sent from the robotic rovers currently gathering information on the planet.32．People used to think that _________A．there was little water on Mars B．Mars had a lot of flowing waterC．a large quantity of ice was Mars D．Mars was much wetter than Earth 33．What do we know about Black Beauty? _________A．It was discovered in Seattle in the USA．B．It is the biggest of 110meteorites from Mars. C．It landed on Earth after an asteroid crash. D．It has a history of 2．1million years. 34．How did the scientists research Black Beauty? _________A．By cutting it into pieces. B．By dipping it into water.C．By burning it on a fire. D．By burying it into a desert.35．The passage is mainly about _________A．A rock from the center of Mars. B．A major Martian meteorite discoveryC．A new discovery on the Red Planet D．A number of meteorites from Red Plane第二节(共5小题,每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项.For college graduates, it is of vital importance to write application letters well. 36 It should state clearly the job you want, and should tell what you have done. It should be simple, human, personal and brief without leaving out any necessary facts.In writing a letter of application, keep in mind that the things a possible employer is most likely to want to know about are your qualifications, your achievements and your aims. 37 If the first few sentences fail to win the reader’s attention, the rest of the letter may not be continued at all. Try to key your opening remarks to the needs orinterests of the employer not to your own needs or desires. For example, instead of beginning with “I saw your advertisement in today’s newspaper” you might say “I have made a careful study of your advertising during the past six months” or I have made a survey in my neighborhood to find out how many housewives use your product and why they like it.”38 Be clear about the kind of job for which you are now applying. College graduates looking for their first positions often ask what they can provide in a letter and what if employers warn experience, which, naturally, no beginner has. 39It is important to write a good strong closing for your letter. Make a specific request for an interview or give the possible employer something definite to do or expect. 40 That makes it easier for a possible employer to get in touch in you.A．Here are a few suggestions for you to prepare yourself better for your interview.B．An excellent idea is to enclose a stamped, self-addressed envelope with your letter.C．The answer is that everything you have ever done is experience.D．Don’t be afraid of being a new hand.E．Try to avoid writing in general.F．The pur pose of a letter of application is to help you to “sell” yourself.G．The opening paragraph is perhaps the most import.第三部分英语知识运用(共两节,满分45分)第一节完形填空(共20小题;每小题1.5分,满分30分)阅读下面短文,从短文后各题所给的四个选项(A．B．C和D)中,选出可以填入空白处的最佳选项,并在答题卡上将该项涂黑.A few years ago I was working part time at a local ice cream shop.
