The villagers were very proud of Salem as he worked long hours and cared about the people in his village. While others were enjoying the prewedding celebrations, together with the nurses, the groom was busy delivering a baby in his clinic.The bride was in her room happily arranging her hair and make-up, getting ready for the arrival of her guests. Her family and friends had excitedly prepared the henna (涂指甲花) party. Grandma and Mum were busy in the kitchen with the food they had made for the henna feast for the day before Friday. Samia’s friend Mariam was making the wedding cake. Her friend Shaikha was collecti ng the bride’s dress from the tailor. At 12 noon the henna maker arrived. Following the tradition, she started decorating the bride’s hands. There was an air of excitement in the room. Grandma started singing a traditional folk song.Suddenly, the bride felt a strange tingling (麻刺感) in her hand. It grew worse and worse. Her hand became red and swollen soon. Grandma said, “Oh dear, I think it best that you wash your hands imm ediately.” As an emergency first aider, Mariam suggested applying some cold cream o n Samia’s hand and ran off and returned with some in her hand. Neither of these worked. Mum took control and phoned Salem but in vain. Without hesitation, she took Samia to the hospital urgently with Dad and other friends. Dr Ahmed looked at her hand and said, “ You’ve had an allergic reaction to the henna. Tomorrow is your wedding. What about drawing the henna using body colors?” Everyone smiled.24.

BCProfessor Sun Jun, aged 93 in 2018, has devoted his life to working on China’s giant construction projects, including the Qinghai-Tibet highway, Three Gorges Dam, and the Yangtze River Tunnel. In his latest project, the Tongji University academic served as a senior adviser on the construction of the Hong Kong-Zhuhai-Macao Bridge.Under the guidance of Sun, Xu Wei, a professor in Tonji and Sun’s student, took over technical assistance for the construction o f the bridge. “Every time I saw Sun and other professors working on the bridge,I felt at ease,” said Lin Ming, the general project manager. Lin initially invited an experienced Dutch company to serve as the technical assistant for the project. The company wanted to charge US $171million. He then asked for help from Xu along with experts in Tongji University.The methods developed by Tongji University reduced theimpact of the bridge on the Chinese white dolphin, which is under first class state protection. The key challenge during the construction of the bridge was the 6.7-km underwater tunnel, the world’s longest and deepest undersea tunnel. Ding Wenqi, who was nickn amed the “ tunnel expert” , was asked to ensure the tubes be connected perfectly—even under the influences of land subsidence (下沉), water pressure and tide movement. Hu Xiangdong, another professor with T ongji, developed a method to freeze the earth around the tunnel to prevent water leakage and land subsidence during the digging of the most challenging 2-km section of the tunnel.The tunnel section of the project was completed in May 2017. Sun was invited to visit the near-completed bridge again in February 2018. The expert said he felt the most relaxed this time since most of the challenges hav e been conquered. “In the next step, we should focus on how tomake the two artificial islands more beautiful and attract travelers,” Sun said.Xu said all the staff in my office took a great pride in watching the TV news of the bridge’s official opening o n Wednesday.28. What is Professor Sun’s contribution to the bridge?A. He worked in Tongji University.B. He was the general project manager.C. He gave much advice on the project.D. He took over the technical assistance.29. Why did Lin Ming ask for help from experts in T ongji University?A. The Dutch company charged too much.B. The technical assistant had too much trouble.C. Tongji University did best in the giant projects.D. He felt relaxed to see professors working on the bridge.30. What’s the gre atest trouble in building the bridge?A. Protecting the Chinese white dolphin.B. Constructing the longest & deepest undersea tunnel.C. Controlling the water pressure.D. Preventing the tide.31. How did the expert stop water leaking in building the undersea tunnel?A. By keeping the tide moving.B. By digging deep into the sea.C. By increasing the water pressure.D. By freezing the nearby earth around the tunnel.DThe regular world presented to us by our five senses—you could call it reality 1.0—is not always the most user-friendly of places. We get lost in unfamiliar cities; we meet people whose language we don’t understand. So why not try the improved versi on: augmented reality (AR) or reality 2.0? AR technology adds computer-produced images (图像) on the real world via a mobile phone camera or special video glasses.Early forms of AR are already here. With the right downloads, smart phones can deliverinforma tion about nearby ATMs and restaurants and other points of interest. But that’s just the b eginning. A few years from now the quantity of information available will have increased hugely. You will not only see that there’s a Chinese restaurant on the next b lock, but you will be able to see the menu and read reviews of it.This is where the next revolution in computing will take place: in the interface (界面) between the real world and the informationbrought to us via the Internet. Imagine bubbles floating before your eyes, filled with cool information about anything and everything that you see in front of you.Let’s jump ahead to ten years from now. A person trying to fix their car won’t be reading a book with pictures; they will be wearing a device that projects animated 3-D computer graphics onto the equipment under repair, labeling parts and giving step-by-step guidance.The window onto the AR world can be a smart phone or special video glasses. But in ten years’ time these will have been replaced by contact lenses (隐形眼镜) with tiny LEDs, which present something at a readable distance in front of the eye. So a deaf person wearing these lenses will be able to see what people are saying.The question is, while we are all absorbed in our new augmented reality worlds, how will we be communicating with each other?32. What does the text mainly talk about?A. The next information technology revolution.B. Early forms of augmented reality technology.C. The differences between reality 1.0 and reality 2.0.D. The relationship between people living in reality 2.0.33. What does the underlined word “it” refe r to in Paragraph 2?A. The menu.B. The block.C. The revolution.D. The restaurant.34. What are tiny LEDs used to do?A. Protect people’s eyes.B. Show text and images.C. Warn users of dangers.D. Replace video glasses.35. What’s the author’s attitude towards AR technology?A. Doubtful.B. Disapproving.C. Favourable.D. Ambiguous.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)[来源:学科]阅读下面短文,从短文后各题所给的四个选项中,选出可以填入空白处的最佳选项。

The villagers were very proud of Salem as he worked long hours and cared about the people in his village. While others were enjoying the prewedding celebrations, together with the nurses, the groom was busy delivering a baby in his clinic.The bride was in her room happily arranging her hair and make-up, getting ready for the arrival of her guests. Her family and friends had excitedly prepared the henna (涂指甲花) party. Grandma and Mum were busy in the kitchen with the food they had made for the henna feast for the day before Friday. Samia’s friend Mariam was making the wedding cake. Her friend Shaikha was collecting the bride’s dress from the tailor. At 12 noon the henna maker arrived. Following the tradition, she started decorating the bride’s hands. There was an air of excitement in the room. Grandma started singing a traditional folk song.Suddenly, the bride felt a strange tingling (麻刺感) in her hand. It grew worse and worse. Her hand became red and swollen soon. Grandma said, “Oh dear, I think it best that you wash your hands imm ediately.” As an emergency first aider, Mariam suggested applying some cold cream on Samia’s hand and ran off and returned with some in her hand. Neither of these worked. Mum took control and phoned Salem but in vain. Without hesitation, she took Samia to the hospital urgently with Dad and other friends. Dr Ahmed looked at her hand and said, “ You’ve had an allergic reaction to the henna. Tomorrow is your wedding. What about drawing the henna using body colors?” Everyone smiled.24.

BCProfessor Sun Jun, aged 93 in 2018, has devoted his life to working on China’s giant construction projects, including the Qinghai-Tibet highway, Three Gorges Dam, and the Yangtze River Tunnel. In his latest project, the Tongji University academic served as a senior adviser on the construction of the Hong Kong-Zhuhai-Macao Bridge.Under the guidance of Sun, Xu Wei, a professor in Tonji and Sun’s student, took over technical assistance for the construction of the bridge. “Every time I saw Sun and other professors working on the bridge,I felt at ease,” said Lin Ming, the general project manager. Lin initially invited an experienced Dutch company to serve as the technical assistant for the project. The company wanted to charge US $171million. He then asked for help from Xu along with experts in Tongji University.The methods developed by Tongji University reduced the impact of the bridge on the Chinese white dolphin, which is under first class state protection. The key challenge during the construction of the bridge was the 6.7-km underwater tunnel, the world’s longest and deepest undersea tunnel. Ding Wenqi, who was nickn amed the “ tunnel expert” , was asked to ensure the tubes be connected perfectly—even under the influences of land subsidence (下沉), water pressure and tide movement. Hu Xiangdong, another professor with Tongji, developed a method to freeze the earth around the tunnel to prevent water leakage and land subsidence during the digging of the most challenging 2-km section of the tunnel.The tunnel section of the project was completed in May 2017. Sun was invited to visit the near-completed bridge again in February 2018. The expert said he felt the most relaxed this time since most of the challenges have been conquered. “In the next step, we should focus on how tomake the two artificial islands more beautiful and attract travelers,” Sun said.Xu said all the staff in my office took a great pride in watching the TV news of the bridge’s official opening on Wednesday.28. What is Professor Sun’s contribution to the bridge?A. He worked in Tongji University.B. He was the general project manager.C. He gave much advice on the project.D. He took over the technical assistance.29. Why did Lin Ming ask for help from experts in Tongji University?A. The Dutch company charged too much.B. The technical assistant had too much trouble.C. Tongji University did best in the giant projects.D. He felt relaxed to see professors working on the bridge.30. What’s the greatest trouble in building the bridge?A. Protecting the Chinese white dolphin.B. Constructing the longest & deepest undersea tunnel.C. Controlling the water pressure.D. Preventing the tide.31. How did the expert stop water leaking in building the undersea tunnel?A. By keeping the tide moving.B. By digging deep into the sea.C. By increasing the water pressure.D. By freezing the nearby earth around the tunnel.DThe regular world presented to us by our five senses—you could call it reality 1.0—is not always the most user-friendly of places. We get lost in unfamiliar cities; we meet people whose language we don’t understand. So why not try the improved versi on: augmented reality (AR) or reality 2.0? AR technology adds computer-produced images (图像) on the real world via a mobile phone camera or special video glasses.Early forms of AR are already here. With the right downloads, smart phones can deliverinforma tion about nearby ATMs and restaurants and other points of interest. But that’s just the beginning. A few years from now the quantity of information available will have increased hugely. You will not only see that there’s a Chinese restaurant on the next b lock, but you will be able to see the menu and read reviews of it.This is where the next revolution in computing will take place: in the interface (界面) between the real world and the information brought to us via the Internet. Imagine bubbles floating before your eyes, filled with cool information about anything and everything that you see in front of you.Let’s jump ahead to ten years from now. A person trying to fix their car won’t be reading a book with pictures; they will be wearing a device that projects animated 3-D computer graphics onto the equipment under repair, labeling parts and giving step-by-step guidance.The window onto the AR world can be a smart phone or special video glasses. But in ten years’ time these will have been replaced by contact lenses (隐形眼镜) with tiny LEDs, which present something at a readable distance in front of the eye. So a deaf person wearing these lenses will be able to see what people are saying.The question is, while we are all absorbed in our new augmented reality worlds, how will we be communicating with each other?32. What does the text mainly talk about?A. The next information technology revolution.B. Early forms of augmented reality technology.C. The differences between reality 1.0 and reality 2.0.D. The relationship between people living in reality 2.0.33. What does the underlined word “it” refer to in Paragraph 2?A. The menu.B. The block.C. The revolution.D. The restaurant.34. What are tiny LEDs used to do?A. Protect people’s eyes.B. Show text and images.C. Warn users of dangers.D. Replace video glasses.35. What’s the author’s attitude towards AR technology?A. Doubtful.B. Disapproving.C. Favourable.D. Ambiguous.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)[来源:学科]阅读下面短文,从短文后各题所给的四个选项中,选出可以填入空白处的最佳选项。
