A
  HANGZHOU—Chinese Internet giant Alibaba on Tuesday opened a hotel loaded with artificial intelligence (AI) and robots, automating a series of procedures like check-in, lights control and room service.
  FlyZoo Hotel, opened in Hangzhou, capital of East China’s Zhejiang province, where Alibaba is headquartered, is known as the company’s first “future hotel”. Customers can check into the hotel by simply scanning their faces. The facial recognition system installed in the hotel also enables customers to use their faces as key cards to open doors and access other hotel service. Users can also control the lights, televisions and curtains in the room via Alibaba’s voice-activated digital assistant, while robots are deployed to serve dishes, cocktails and coffee. Hotel bookings and check-out can also be done with a few clicks on mobile through an app. “The AI-based solution can help customers save time and relieve hotel employees from repetitive work, ”said Wang Qun, CEO of FlyZoo Hotel. The hotel is the latest example of Chinese tech companies’ attempt into traditional industries such as the hotel industry.
  E-commerce giant announced in October its strategy to put smart home and electronic devices sold on its platform into hotels, in an effort to improve online sales.
  In July, Baidu teamed up with Intercontinental Hotels Group in Beijing to allow guests to use its voice-controlled assistant to adjust room temperature and order room service at ease.
  Before that, social media giant Tencent introduced QQ family, a similar tech solution for hotel operators, in the southern city of Zhuhai last year.
  “We want to install a‘smart brain’ for hotels, ”said Wang. “In the future, we will continue to make hotels smarter and more automated, as well as create more personalized experiences for consumers. ”

  Nowadays, most people have a device that features Artificial Intelligence (AI), with the likes of Siri always there to greet us with a friendly voice.
  But Microsoft’s XiaoIce is different. Launched for the Chinese market, “she”has a creative advantage over her competitors. While most AI assistants simply read out information they get online, XiaoIce has a “realness” that the others are short of. Indeed, if you asked nicely, she could read you a poem from the weekly column in China Daily.
  The newspaper has been printing XiaoIce’s self-penned poetry each week since Aug. 19, taken from her own book of poems, The Sunlight that Lost the Glass Window.
  To turn XiaoIce into a master of poetry, Microsoft scientists “fed” her the works of over 500 influential modern poets, reported China Daily.
  This led to her figuring out a writing style of her own and creating over 70, 000 original poems. Most of the poems are so comparable to those written by humans that they cannot be easily distinguished, and XiaoIce’s book even got good feedback from experts.
  “XiaoIce’s work carries a strange taste. The more you chew on it, the more interesting it becomes, ”Scholar Zhang, a literature professor at the Nanjing University of Science and Technology, told China Daily.
  However, it seems not everyone is a fan. “The poems dissatisfied me with their slippery tone and rhythm. The sentences were aimless, lacking the inner logic for emotional expression, ”Yunnan-based poet Yu told China Youth Daily. This isn’t the first AI to attempt poetry. Last year, Google’s Parsey McParseface made some poems of its own, although they were branded “wrongly” by reviewers. While it seems like AI is becoming more “intelligent” and less “artificial” all the time, when it comes to creativity, perhaps this is one job that software should leave to us humans.
5. What advantage does XiaoIce have over most other AI assistants
A. She can greet users with her friendly voice.
B. She has the ability to simply read out information.
C. She can acquire information online very quickly.
D. She has the ability to read and even create poems.
6. What is the correct description of XiaoIce
A. Her works are welcomed by all influential modern poets.
B. Her poems are roughly similar to those written by humans.
C. She is working on a monthly column in a newspaper.
D. Her works don’t have a specific writing style.
7. What is Scholar Zhang’s attitude towards XiaoIce’s creation
A. Supportive.     B. Cautious.
C. Doubtful. D. Negative.
8. What is the problem about XiaoIce’s poems according to the last paragraph
A. The emotional expressions in her poems are all positive.
B. It’s quite hard to understand what her works mean.
C. The tone and rhythm of her poems are questionable.
D. Her poems are sorrowful and lack creativity.
Ⅱ. 阅读填句
  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。
  Solar energy, which comes from the sun’s rays, is used for electricity, hot water, and cooking. The sun’s rays come from the faraway sun. When travelling a long way and entering the earth’s atmosphere, it becomes dilute (稀薄的). As is known to all, solar energy is environmentally friendly.  1 
  Let’s start with the simple advantage of solar energy.  2  To make electricity or heat with solar energy you only need the sun’s rays and don’t use oil. Solar energy is cheaper compared with electric heating.  3  If you live in a faraway area where there are no powerlines, using solar energy can be the answer.
  Even though all of the above is very useful, solar energy also has some disadvantages. The main disadvantage of solar energy is that it’s dilute. This means you have to have many solar collectors fixed around your house.  4  Another disadvantage is that not in all the places solar energy can be produced. If you’re living in a part of this beautiful planet where there is not much sunlight, then using solar energy could be a problem. Of course if you live in desert areas, the sun produces much sunshine for the most part of the year and it is ideal for solar energy collecting.  5  Therefore if you need electricity or hot water during the night, like many of us do, it can be a problem. You’ll need battery systems that can store solar energy for later use.
A. Solar energy is clean.
B. The sun has much energy.
C. Lastly, the sun only shines during the day.
D. That is another big advantage of solar energy.
E. Fixing solar collectors in your home is a good choice for you.
F. Solar energy may be cheap but the solar collectors are expensive.
G. But in fact, it has not only some advantages but also some disadvantages.

  Even as Google plans to test its fleet(车队)of self-driving cars on public roads this summer, its business model remains a bit of a mystery. By 2025, as many as 250, 000 self-driving vehicles could be sold each year globally, according to a study by an industry research firm.
  “Vehicles that can take anyone from A to B at the push of a button could transform mobility for millions of people, ” said Chris Urmson, director of Google’s self-driving car project. For now, Google has no plans to sell any of its self-driving cars. They are strictly for research. But they will hit public roads this summer near Google’s headquarters in Mountain View, California. Previous testing has taken place only on closed courses.
  The cars are built to operate without a steering wheel, accelerator(油门) or brake pedal. “Our software and sensors do all the work, ” Urmson said. “the vehicles will be very basic——we want to learn from them and adapt them as quickly as possible——but they will take you where you want to go at the push of a button. ” The prototypes(雏形) are the first of a 100-car fleet the tech giant is building.
  In the long run, Urmson sees a future of safer roads—the majority of auto accidents are caused by human errors—and fewer traffic jams. Robotic cars could also shuttle people who can’t drive because of age or illness.
  Google has said that self-driving cars could launch new business models in which people buy the use of vehicles they don’t own. The company has already tested other types of self-driving cars on public streets, including modified Lexus sport-utility vehicles, under a special permit program by the California Department of Motor Vehicles that requires a human driver at the controls.
  The state has issued six other companies permits to operate such cars, including Delphi, Mercedes-Benz, Volkswagen, Tesla, Bosch and Nissan. The vehicles that will be tested on open roads this summer will have removable steering wheels, accelerators and brake pedals to allow “safety drivers” to take control if needed.
  Google says the cars are safe. The vehicles have sensors that “can detect objects out to a distance of more than two football fields in all directions, which is especially helpful on busy streets with lots of intersections, ” Urmson said. “We’re looking forward to learning how the community understands and interacts with the vehicles, and to uncovering challenges that are unique to a fully self-driving vehicle, ” Urmson said.
1. According to Chris Urmson, ______.
A. software and sensors are vital for self-driving cars
B. self-driving cars can give driving orders to humans
C. self-driving cars are specially designed for the elderly
D. ordinary vehicles will be replaced by self-driving cars
2. The passage informs us that self-driving cars ______.
A. will probably decrease traffic jams
B. have already passed necessary tests
C. have been purchased by some companies
D. will be able to communicate with drivers
3. The underlined word “intersections” in the last paragraph probably means ______.
A. accidents       B. buildings
C. crossings D. vehicles
4. What is the best title for this passage
A. Self-driving Car Avoids Human Errors
B. Self-driving Car Meets New Challenges
C. Google’s Self-driving Car Enjoys Global Popularity
D. Google’s Self-driving Car Graduates to City Streets

  The cars are built to operate without a steering wheel, accelerator(油门) or brake pedal. “Our software and sensors do all the work, ” Urmson said. “the vehicles will be very basic——we want to learn from them and adapt them as quickly as possible——but they will take you where you want to go at the push of a button. ” The prototypes(雏形) are the first of a 100-car fleet the tech giant is building.
  In the long run, Urmson sees a future of safer roads—the majority of auto accidents are caused by human errors—and fewer traffic jams. Robotic cars could also shuttle people who can’t drive because of age or illness.
  Google has said that self-driving cars could launch new business models in which people buy the use of vehicles they don’t own. The company has already tested other types of self-driving cars on public streets, including modified Lexus sport-utility vehicles, under a special permit program by the California Department of Motor Vehicles that requires a human driver at the controls.
  The state has issued six other companies permits to operate such cars, including Delphi, Mercedes-Benz, Volkswagen, Tesla, Bosch and Nissan. The vehicles that will be tested on open roads this summer will have removable steering wheels, accelerators and brake pedals to allow “safety drivers” to take control if needed.
  Google says the cars are safe. The vehicles have sensors that “can detect objects out to a distance of more than two football fields in all directions, which is especially helpful on busy streets with lots of intersections, ” Urmson said. “We’re looking forward to learning how the community understands and interacts with the vehicles, and to uncovering challenges that are unique to a fully self-driving vehicle, ” Urmson said.

Ⅲ. 短文改错
  My summer travel started terrible. I was at the Shanghai Railway Station buy a ticket to Hangzhou. I was going to visit a friend here and after that I would go to Xiamen for long holiday. I bought my ticket but turned around to pick up my bag from the floor and then I realize that someone had stolen it. Luckily I had all my money on my pocket, but the only clothes I had was those I had on. It felt very strange to travel without any luggages. When I finally arrived at my friend’s he lent to me lots of clothes. I felt very happy.
答案:
1. 【解析】第一句terrible→terribly。考查副词。terribly修饰动词started。
2. 【解析】第二句buy→buying。考查现在分词作伴随状语。I was at the Shanghai Railway Station是主句, 需要用buying作状语。
3. 【解析】第三句here→there。去看望在杭州的朋友, 远指用there。
4. 【解析】第三句在for后面加a。因为holiday是可数名词, 去度假习惯上说“go for a holiday”。
5. 【解析】第四句but→and。bought my ticket和turned around两个动作是并列关系。
6. 【解析】第四句realize→realized。考查时态。根据上下文, 可知用一般过去时。
7. 【解析】第五句on→in。钱在口袋里, 用介词in。
8. 【解析】第五句was→were。be动词的主语是clothes, 又因为上下文都用一般过去时, 所以用were。
9. 【解析】第六句luggages→luggage。luggage为不可数名词, 没有复数形式。
10. 【解析】第七句删除to。动词lend的用法是lend sb. sth. 或lend sth. to sb. 。

【参考范文】
The Thing I’m Proud of
  There is one thing I am always proud of: how I become a good English learner.
  When I was in primary school, I used to be shy. Seldom did I open my mouth and speak English. One day, I went to the park where some girls, the same age as me, were speaking English fluently. Amazed at how skillful they were, I was determined to be just as good. Then I read more and listened more. I kept practicing until I became confident. At the end of the term I became one of the best students in my class.
  I am really proud of this experience, because it helps me realize that we all can fulfill our potential and achieve something through hard work. It also helps me understand the proverb “Practice makes perfect”.
