??? For people, it's not surprising that we can open a door, lift a heavy box and control ourselves while walking in the snow. But can a robot do these? Well, Google's new robot, Atlas, can not only do these things, but it can stand up if it falls down. Although the robot may be slow and clumsy, it was created mainly to work in dangerous places for humans.
??? Now, robots are much smarter than you might imagine. On March 9 this year, AlphaGo, an artificial intelligence(人工智能) program made by Google's DeepMind, challenged top professional Go player Lee Sedol from South Korea. And AlphaGo beat Lee at last.
??? AI is when computers or computer software is able to have intelligent behavior, such as thinking or acting like a human. In our daily life, we already use AI in many ways, such as Apple's Siri and search engines like Baidu and Google.
??? Some people may worry whether computers are now smart enough to beat us at everything. But experts say that is not the case. Real life problems can be more difficult than the Go game. For example, humans can watch a person throw down a cup of coffee and know that the result will be a mess on the floor. A computer program would have to know the size of the cup, the height of the cup from the floor and many other things to find out the result. But we never know what will happen in the future.

??? Imagine having a simple app (应用程序) that works like this: When you need help, just open the app, touch the "not OK" button and a text message will be sent to five preselected (预先选定的) people, along with a location (位置) to show where you are. The message reads, "Hey, I’m not OK. Please call me, text me, or come to find me."
??? US teenagers Hannah Lucas, 15, and her brother Charlie, 13, have created an app called not OK. People just need to pay $1.99 (12.5 yuan) each month to use it.
??? Hannah was inspired (启发) to create the app during a dark time in her life last year. She suffered from a disease that caused her to pass out at school. Other kids sometimes bullied (欺凌) her about this. She felt sad and wanted to find an app that would allow her to get help when she wasn't feeling OK.
??? She asked her brother Charlie, whose nickname is "Tech Support", to find such an app. When they couldn't find one, they decided to create one themselves.
??? They came up with some designs for the app first. Charlie took a programming class last summer and built a website for the app. Hannah also shared her idea in her summer business class. Some app developers showed interest and decided to help her. At last, the app came out in the US and Canada on January 31.

??? If you look at the top of your phone, you'll usually see a little symbol that says 3G or 4G. The "G" stands for the "generation"(代)of your mobile network. But the symbols will become things of the past after 5G networks fully arrive.
??? On March 30, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone. Shanghai has also become the first city in China to start testing 5G networks.
??? About 100 times faster than 4G networks, 5G will let people download and upload data (数据)faster than ever before. But 5G won't just bring faster mobile internet. People can use it for many other things as well.
??? For example, 5G will help to make self-driving cars safer. Today's self-driving test cars have one problem—lag (延迟).When the car "sees" an obstacle (障碍物), it sends this information to a data center and receives instructions. However, it will be some time before it sends and receives this information. With this kind of lag, the cars might crash because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.
??? 5G could also be used to power the internet of things (IoT) , that is, a large online network that connects all things and people. Fast internet speeds will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically (自动地)place an order online for eggs when it finds that there are no eggs left inside.

A.explain how 5G's fast speed can be helpful
B.warn about the possible dangers of self-driving cars
C.explain how self-driving cars work

A.A robot that can do housework.

??? Some people are happy about those new ways of shopping and communication (沟通). Others do not think that computers will replace (代替) our old ways of doing things.
??? Some people think that one day we will not read books made of paper, because we can buy and read books on the computer.

Xiaofan, a smart boy from Shenzhen, used to have difficulty in getting up on time, and his alarm clock was of no use at all. It made him very upset. One day, he had a good idea.
Xiaofan went to a shop and bought a tape. Back home, he started to record what he wanted. After that, he took out a tool box and connected his tape player with the new tape to his alarm clock. A special alarm clock was born. At a certain time in the morning, the tape player would play soft music with a low and sweet voice of a young girl, "Wake up, please." Five minutes later, the tape player would play again, and it might be loud music. At the same time, he could hear a recording of his parent, "Wake up at once, or you’ll be late!"
Several days later, Xiaofan got used to the sound of the recordings. After the recordings, he was still sleepy, and even fell asleep again. That was terrible! So he went to the library and borrowed plenty of books home to deal with his problem of getting up late.
He made it! With the help of what he had learned from the books，he put a mechanical(机械的）arm at the end of the bed. Now if Xiaofan still doesn’t get up at last, the arm in the bed will "beat" him, and even make him out of the bed.

??? To help Japanese companies better deal with the increasing number of foreigners visiting the country, Panasonic has created a megaphone (扩音器) which is able to smartly translate Japanese into English, Chinese and Korean.
??? Panasonic named the product "Megahonyaku". It is a term for the Japanese words for "megaphone" and "translate", which actually makes g lot of sense because it's a megaphone that can translate Japanese into several other languages in real time. When a user speaks Japanese into the megaphone, it recognizes (辨认) and translates what is being said immediately, and outputs the words in English, Chinese or Korean.
??? It sounds amazing, and seeing it in action is wonderful, but Megahonyaku is not good enough. It cannot translate everything you say, as it only stores 300 common expressions, like "The train has been put off" or "Watch your step". However, the Japanese company behind Megahonyaku promises to add new expressions regularly, which users can get on the Internet.
??? The machine was designed to be used in places like transport stations, airports and places of interest where quick and exact announcements are needed most. Around 30 Japanese organizations, including the police and guides, have been trying out Megahonyaku for about one year, but Panasonic says it will come onto the market on December 20th. Instead of selling these speech translators, Panasonic plans on renting (出租) them out for less than $183 a month on a three-year agreement, and offering users future improvements and necessary services.
??? Panasonic has also said that it may add support for other languages, like Russian, depending on customers' needs. Megahonyaku also includes a touch screen that allows users to choose the language they need their speech translated into.
(1) Panasonic has produced Megahonyaku so that ________.
A.?guides can translate Chinese into Japanese faster
B.?Japanese companies can receive foreigners better
C.?foreigners can talk with the Japanese freely
D.?the Japanese can learn other languages easily
(2) The third paragraph is mainly about the ________ of Megahonyaku.
A.?invention????B.?importance????C.?disadvantage???D.?history
(3) It can be learnt from Paragraph 4 that Megahonyaku ________.
A.?may be popular with the police B.?is widely used in private homes
C.?will be sold on December 20th D.?stores about 30 foreign languages
(4) According to the passage, Panasonic will ________ in the future.
A.?sell Megahonyaku to foreign visitors B.?bring down the price of Megahonyaku
