The firemen were surprised that Mr Johnson did not come out of the house, and two of them went inside to look for him. But Mr Johnson was not in the house. In the bedroom the two firemen found an open safe(保险箱) which was empty. There were papers on the floor. The windows of Mr Johnson's bedroom on the ground floor of the house were open.

My husband Mr Smith went to bed at about half past ten. The servants had already gone to their rooms. Only my housekeeper stayed in her room at the top of the house until I needed her.I read a book in this room until after eleven. Then I walked round to make sure that all was right before I went upstairs(楼上). I went into the kitchen, the storeroom, the living room and finally the dining room. As I came near the window, which was covered with thick curtains(窗帘), I suddenly felt the wind blow on my face and realized that it was open. I pulled the curtain to one side, and found myself face to face with a man who had just walked into the room. By the light of my bedroom candle, I saw two other men entering behind the first.I was so scared, walking back quickly, but the man was on me in a minute.He caught me first by the wrist(手腕) and then by the throat.I tried to shout, but he hit me heavily over the eyes, and I fell to the ground. I must have been unconscious for a few minutes. When I woke up, I found they had tied me to the chair, and a scarf round my mouth stopped me from making any sound. At this time, my unlucky husband came into the room. He had certainly heard some suspicious(令人怀疑的) sounds, and he came prepared.

For example,police use it to search for bad guys (家伙). It's also used to unlock phones or doors. Now, a similar technology, known as facial detection (探测), is entering a new field: the business of advertising.Such systems are going through tests in a small number of stores. One facial detection system can tell a person's "happiness" or "fear" level. That helps businesses see how people feel as they look at products or advertisements in the store. Another system can detect whether someone is wearing eyeglasses. If so, stores can send advertisements for new glasses to him.Facial detection technology is also placed inside some large advertising boards. Cameras in those boards can detect information like people's ages and five levels of feelings-from "very happy" to "very unhappy".Supporters of the technology say it could improve buyers' experience by showing products they might like or by offering them products at lower prices.Some are against the idea of using such systems. Pam Dixon,the head of a privacy (隐私) group, is one of them. She thinks the strange actions may cause something unfair. For example, a business could raise the price of a product according to a person's age and feelings.However, one store testing the technology explained they wouldn't store people's information like names or ages. And the advertising board system maker said it didn't keep any personal information or record any videos.(1).Facial detection technology can tell people's according to the passage.A.weight B.feelings C.height D.jobs (2).What does the underlined word "they" in paragraph 2 refer to?A.Businesses B.Systems.C.Customers.D.Advertisements.(3).We can infer from the text that facial detection technology .A.can detect buyers' names and record themB.can't store personal informationC.may be used to sell cheaper goods in all storesD.may need some time before being widely used(4).The structure of the text is .A.B.C.D.(5).The text is mainly about .A.facial recognition technology entering a new fieldB.facial recognition technology looking for bad guysC.facial detection technology going into advertising fieldD.facial detection technology improving buyers' experience参考答案一、【答案】Early;Where;Moonlight;manager;caught;thirty/30;empty;keys;find;missing/lost/gone 【解析】文章大意:今天一早,东镇发生了可怕的事情。

九年级英语中考强化阅读训练四(附答案)一、完形填空I believe what my grandmother taught me: “Nothing bad happens without something good coming of it.”For years I didn’t 1 this saying at all. Being optimistic(乐观的), I thought of it as a “When one door closes another opens” kind of thing. Only recently, after a long period of hard times, I really understand the 2 meaning of my grandmother’s saying.The first difficult wave (海浪) came when my first child was born with a heart disease, requiring an open-heart 3 when she was only seven months old. Another was needed when she was two. Our business went 4 bad times, just when we were struggling (斗争)with a flood of medical bills. Then my husband started having back pain that left him unable to move for months. Finally our family was under great economic pressure (经济压力).We’ve spent a few years 5 from the ruins (废墟) of our dreams and hopes, and through it all I’ve 6 begun to understand what this saying had to teach me. It wasn’t about a chance 7 . It wasn’t about doors opening. For me, it is 8 what forms beyond the ruins at our feet.It’s not a 9 sweeping change in my nature. Instead, it’s the building of small things. Today I face each day with three new abilities: being 10 , simple, and thankful. This is 11 I have got from the pounding surf (猛烈冲浪) of the last few years.The good that comes, is our ability to 12 and adapt(适应). In the remains left by unlucky things, I’ve learned new skills to deal with my rebuilt world. Over time I am better able to survive the pounding of the waves, and even learn to 13 the beauty of the surf.I would be lying if I didn’t say we’ve got enough 14 , and that I don’t hope for quiet waves. But I know that through it all, my abilities will grow and the 15 will come.( )1.A.remember B.understand C.believe D.explore( )2.A.true B.real C.wrong D.same( )3.A.examination B.condition C.operation D.protection( )4.A.onto B.across C.through D.over( )5.A.falling B.digging C.getting D.rising( )6.A.quickly B.easily C.slowly D.hardly( )7.A.at all B.in all C.above all D.first of all( )8.A.below B.without C.about D.in( )9.A.pleasant B.great C.welcome D.small( )10.A.sad B.quick C.modest D.proud( )11.A.which B.what C.how D.whether( )12.A.communicate B.choose C.grow D.discover( )13.A.avoid B.enjoy C.prevent D.stop( )14.A.strength B.information C.punishment D.memory( )15.A.smile B.wave C.good D.bad二、阅读理解AA famous artist and educator in the San Francisco Bay Area will be remembered as a pioneer in art exchanges between the famous artist and educator in the United States and China, and his legacy is expected to continue inspiring collaboration(合作) between the two countries.Fred Martin(1927-2022) was a painting professor at the San Francisco Art Institute for more than 50 years. While working as a leader, Martin started the first art exchange programs between the US and China in the 1980s. During his career, he contributed to the training of art talent in China as well as the research and development of Chinese contemporary (当代的)art.In memory of his great contributions, an exhibition named Lifetime of Devotion: The Art of Fred Martin was held at the Silicon Valley Asian Art Center in Santa Clara,California. The exhibition ran through to March 8 and featured about 30 paintings by the artist.“The artistic connection between East and West was an important part of Fred's life. There was a deep connection between Fred and the whole culture of China,”says Michael Grady, a former partner of Martin's and a professor of the art studio at Appalachian State University.“His use of handwritten text and his artworks were made of paint on paper. So he was easily accepted by Chinese artists as they share a common source (来源) of encouragement from both classical and modern Chinese art,”says Grady. Grady actually attended the opening celebration of the exhibition on February 25.Martin started his trip to China as early as 1986 with teachers and students from the art institute. He helped to make the school one of the first Western art institutes to have exchange programs with China since the country's reform and opening-up started in 1978.In following years, Martin and his colleagues(同事) and students visited China to study Chinese culture and art, and they also gave lectures and held exhibitions. In return, the art institute has received and helped educate many famous Chinese artists over the past thirty years.From 1988 to 2017, Martin held several solo exhibitions at universities and museums in Shanghai, Hangzhou, Shenyang and other cities across China.1. What is the purpose of writing Paragraph 2?A. To show some of Martin's famous paintings.B. To tell the time when Martin worked as a painting professor.C.To praise Martin's work for the development of Chinese modern art.D. To name Martin as a pioneer in art exchanges between the two countries.2. Martin can easily be accepted by Chinese artists because________A. he painted on paperB. he created many paintingsC.he worked as a leader at an art instituteD.he started the first art exchange programs3. What did Martin do in art exchanges between the two countries?①He taught Chinese culture and art. ②He studied Chinese culture and art at a Chinese university.③He helped educate many Chinese artists.④He gave lectures and held exhibitions in China.A.①②③B. ②③④C. ①②④D.①③④4. In which section of the newspaper can we read the passage?A.Fashion.B. Health.C. Travel.D.People.BEver wondered why your virtual(虚拟的)home helper doesn't understand your questions? Or why your navigation app took you on the side street instead of the highway? In a study published April 2lst in the journal iScience, Italian researchers, Arianna Pipitone and Antonio Chella, designed a robot that "thinks out loud".To explore how inner speech might influence a robot's actions, the researchers built a robot called Pepper that speaks to itself. It has the ability to reason and think. They then asked people to set the dinner table with Pepper according to etiquette(礼仪)rules. In one experiment, the user asked Pepper to lay the napkin at the wrong place, going against the rules. Pepper started asking itself a series of self-directed questions and concluded that the user might be mistaken. To be sure, Pepper confirmed the user's order, which led to further inner speech."Ehm, this situation troubles me. I would never break the rules, but I can't make the user unhappy, so I'm doing what he wants, "Pepper said to itself, laying the napkin where it was required to be. Through Pepper's inner voice, the user can learn Pepper was facing a difficult situation and solved it by prioritizing the user's order.Comparing Pepper's actions with and without inner speech, Pipitone and Chella discovered the robot had a higher task-completion rate when having self-dialogue.However, some people find the robot spends more time completing tasks when it talks to itself. The robot's inner speech is also limited to the knowledge that researchers gave it. Pepper's designers still say their workprovides a framework(构架)to further explore how self-dialogue can help robots focus, plan, and learn. "In some ways, we are creating a generational(世代的)robot that likes to chat. From navigation apps and the camera on your phone to medical robots in the operation rooms, machines and computers alike can take advantage of this chatty feature, "says Chella.1. Why does the writer ask two questions at the very beginning of the passage?A. To draw the reader's attention to the topic.B. To show the writer likes electronic products.C. To tell the reader about the history of robots.D. To prove the writer often faces trouble in life.2. Why was Pepper asked to lay the napkin at the wrong place?A. To see how much time Pepper spent laying the napkin.B. To confirm how popular Pepper was among its users.C. To test how many etiquette rules Pepper remembered.D. To study how self-dialogue might influence Pepper's actions.3. What does the underlined word "prioritizing" in Paragraph 3 mean?A. repeatingB. dealing with firstC. going againstD. complaining about4. What can we infer from the passage?A. The designers are proud of their work about Pepper.B. Pepper has already been in use in the operation rooms.C.

Confucius regarded the “Drum Dance”highly. It is also the origin of the Chinese phrase “guwu”which means “embolden”(大胆) in English.The drum was mentioned in Chinese history in the Pottery Age. The Zhou dynasty set up the drum music institution that was responsible(负责的) for the management of officers known as “drum men”and developed a complete drum music system. From then on, drums came to be used in ancient Chinese practices such as sacrifice(祭祀), military(军事), labor(劳动) and other activities.In ancient China, agriculture was the main form of production and drums were considered indispensable(不可或缺的) for a good harvest. Since the sound of drums echoes that of thunder, it was believed that playing drumscould attract rain. So the instrument was used to pray to the gods for good weather and to “communicate”with them.Drums also played a part in the war. Because of a strong resonance effect(共振作用), the drum’s sound could go very far while increasing fear in the heart of the enemies. So the drum was used as a military booster for a long time.In the Tang and Song dynasties, the society was developing fast and drums were widely used. The national band, drama, folk art. song and dance, boat racing, lion dance, festival gathering and labor competition were all together with the beats of drums. The sound of drums became synonymous(同义的) with celebrations, filling hearts with joy.Different types of Chinese drums exist today. For example, “Taiping Drum”is used to express hope for peace and prosperity(繁荣) while “Ansai Waist Drum”is meant to show the spirit of the Loess Plateau(黄土高原) and the heroic character of farmers in Northwest China. Kaifeng has “Pan Drum”, and Luochuan of Shaanxi Province is known for its “Bie Drum”. There are also some cheerful and time-honored drum dances such as “Fengyang Flower Drum”in Anhui Province and “Fishing Basket Flower Drum”in Jiangsu Province.The drums play an important role in their local culture.In a word, drum culture reflects the stability(安定) and prosperity of Chinese society.

Unit 1 How can we become good learners?过模拟If you put your history notes under your pillow and sleep on them the night before an exam, will you do any better in the exam? Most of us have hoped this might help. However, knowledge can’t go through the pillow into your brain. But that doesn’t mean you can’t learn while you are asleep.Scientists aren’t exactly sure how it works, but they have discovered that the brain can learn things during sleeping hours.In one experiment, researchers gave German speakers some Dutch words to learn. Then, they divided them into three groups. The researchers played the Dutch words for people in Group 1 while they were asleep, without telling these German speakers what they were doing. The sound was low so it didn’t wake them up, and only the newly introduced words were used.Another group listened to the same words while they were awake. The researchers found the people in Group 1 were better able to identify and translate the words later. This was true only for the words that were played while they slept. The third group listened to words when they walked. The walkers didn't have the same success in remembering the words as the sleeping group.The researchers later found that people had more slow-wave brain activity all over the night. They said that more slow waves made people have a better memory for the new words.1.When did the researchers play foreign words for people in Group 1 in the experiment?A. Before they went for a walk.B. Before they went to bed.C. When they were asleep.D. When they were having dinner.2.What does the underlined word "identify" mean in Chinese?A. 提高B. 辨认出C. 隐藏D. 逃避3.The last two paragraphs tell us the experiment's______.A. resultB. reasonC. influenceD. purpose4.Which of the following is true?A. Scientists think people can't learn during sleeping hours.B. German speakers enjoy learning Dutch words.C. Slow-wave brain activity can help people have a good sleep.D. People in Group 3 didn't remember the words as well as those in Group 1.5.Where is the passage most probably from?A. A history textbook.B. A science magazine.C. A travel newspaper.D. A modern novel.答案解析【解题导语】人在睡觉的时候大脑也可以继续学习吗?看看本文是怎么说的吧。
Music in SchoolsCan you play a musical instrument? Where did you learn to play it? If you were a pupil in a British school, you would most probably learn at school. Approximately 25% of British pupils learn an instrument. What's more, of the 75% that don't, 40% would like to.But what instruments do the pupils learn to play? Traditionally, school chi ldren learnt classical instruments, such as the piano or violin. This is still true today. Younger children often learn the recorder. As they get older, they start to play the violin or piano. In fact, nearly one out of five music studentsis learning the violin. The piano, or keyboard, is more popular with older children at secondary school.However, things are changing. More pupils than ever before are now lear ning the guitar. As many as 16% of pupils learning an instrument are strumming(漫不经心地弹奏) its strings(弦). Paul McManus, the Chief Executive of the Music Industries Association told the Telegraph(电讯报) newspaper that new British bands like Franz Ferdinand(法兰兹·费迪南), the Arctic Monkeys(北极猴子乐队) and Razorlight (激光乐团) had made playing the guitar 'cool' again. This, perhaps, is why more children are now learning the guitar.British schools do not just offer lessons for instruments. All pupils learn music together as a class. These classes have been changing, too. In the past, the focus of classes was very much Western classical music. But the classes nowcover a far wider range of styles, including folk music and world music. In a recent study by Keele University, 64% of boys and 70% of girls said they enjoy music lessons as a class. They like singing, playing instru- ments and find the lessons fun. Many schools have orchestras and put on concerts each term. It is also common for pupils themselves to form their own bands, copying their rock and pop heroes.In conclusion, music plays a big part in British schools. Pupils can study an instrument, play music together as a class and even take part in concerts and plays.。

"In NBA, he looks like a fourth﹣grader among a group of high school students, "according to The Atlantic.How can he compete (竞争)with them? Robinson makes up for this with his ability to jump.Without moving forwards or backwards, he can jump up to 110cm. However, confidence helps him more. "People talk about my height all the time, but I don't really feel smaller than anyone else, "said Robinson. "I always think I'm on fire(充满激情的). "No matter who you are or what you've won, he's going to come at you. With that spirit, he has won the NBA Slam Dunk Contest threetimes.

But Mr. Zeng wondered why the young man gave him money. The young man said, "A few years ago my father had leukemia(白血病)and you gave me some money for help. Now I want to pay the money back to you."Mr. Zeng finally remembered the young man named Xu Tao, a university student in Beijing. Xu 'Tao asked strangers for raising money to help his father on the Internet when he knew his father had leukemia 3 years ago. "I promise that I will give the money back to you in 3 to 5 years. "Xu Tao said in the article.As time went by, many helpers almost forgot this thing, but Xu Tao did not. It is not easy for Xu Tao and his family to pay back the money of 550, 000 yuan.

That's probably why I am writing this, because it seems an easier way of telling you how thankful I am to you.When I first got ill two years ago and had to be taken to hospital, you were the first person I called to tell, maybe because I knew Mum wasn't going to answer her phone, but probably because you are the first person I call in an emergency.As one illness turned into another and I was stuck in hospital for weeks, feeling sorry for myself, you were still at my beside trying to talk to me to cheer me up. The illness hit my kidney(肾) and we then realized that I was going to need a transport sooner or later. You put yourself forward to be tested as soon as possible and it turned out you were a perfect match.Then last year, in March, we both went down for the operation. I woke a few hours afterwards and felt better. It wasn't until the following day that we got to see each other again. We hugged silently and asked one another how we were. But I never said the words I should have—thank you. To this day, I still haven't said those words to you for my kidney.In the month after the operation, when we were both at home recovering, I made you lunch, went for walks with you. It's my way of saying that I care for you a great deal and that I am truly thankful for what you did for me.I want you to know that my silence towards you and the times you tried to talk to me and got nothing weren't because of you.

They show off things like foods and drinks. Stars have many social media followers. Many of them build ads into their posts (帖子). So do other famous people.Nancy, a 17-year-old teenager did a study into social media ads. She wanted to see if people share unhealthy foods and drinks. Nancy made a list of famous people on social media first. She picked 100 actors, 100 singers and 100 influencers (网红). She looked for posts about foods and drinks. Then, she gave a grade for each of them. The grade showed how nutritious the food or drink was.Nancy found that influencers shared the most foods and drinks by far. They also shared the most sweets which had an unhealthy grade. Nancy was surprised. She thought influencers would share healthier things. Fruits, vegetables and water were least shared by all three groups. Influencers often shared soft drinks. So did singers.Influencers are often friendly and seem close to us. So young people are more likely to believe them. Many users are under 18 years old. “They should be kept away from unhealthy ads, " Nancy says."There should be new rules."
