China' s first artificial intelligence (Al) textbook for high school students 1.( bring) out last week, following a plan by central government 2.( include) Al courses in primary and sec-ondary school.
The nine - chapter textbook, 3.( name ) " Fundamentals of Artificial Intelligence" , was written by outstanding 4.( scholar) from well - known schools nationwide, under the joint ef forts by the research center for MOOC at East China Normal University and Al startup SenseTime.

It may not be the best way to go about meeting new people, but chat rooms are still among the most popular channels. Want to chat with a stranger now? 1., after which, you need to keep the following rules in mind.
2.. Details such as your phone number and home address or where you attend classes should remain personal. It is actually not a very good idea to share your last name with a stranger. Even if you feel you have met someone you really like and get along with, it is still necessary to withhold some important details.
Be fun and chat about something personal. This doesn’t mean giving away personal details, but you can share your life experiences and stories with strangers as long as you are both going with the flow. There is really no way you will manage to know the strangers better unless you both go beyond your hobbies. 3..
Remain in control at all times. There is really no obligation on you to continue with chats that scare you or make you uncomfortable. 4.. As soon as something annoys you, feel free to leave the chat. Let nobody force you into conversations you find inappropriate.
Try not to download things from strangers. 5., but be careful that you don’t get viruses or hacked by such downloads. You really can’t be sure of who you are talking to, so be cautious about downloads. It is best that you stick to the channels of communication made available to you and also make sure that you have the right computer protection even when you download things.
A. Chat rooms make it possible to share all manner of files
B. Avoid sharing your personal details with random strangers
C. So do not be afraid to get a little personal in your random chats
D. At night it’s not appropriate for teens to stay in chat rooms alone
E. Many files with viruses are often purposefully spread on the website
F. Then you should start by finding a chat room reflecting your interests
G. Remember you are chatting for fun and you should remain fully in control
Fairs and theme parks never seem to lose their attraction. My kids love them as much as I do. Not everyone will agree with me though. My wife is terrified of anything more exciting than the merrygoround. So why do I love Blackpool’s Big One while she goes white on hearing the word “rollercoaster(过山车)”？
According to psychologists, it comes down to something called a “Type T” personality. Type T’s are thrillseekers who welcome the uncertainty of activities that most people would find hairraising. It seems some of us enjoy the physical sensations associated with fear: the adrenaline(肾上腺素) rush and the beating heart. Scary rides make us feel alive. Terrifying experiences encourage a sense of excitement once we’re back on solid ground though we only enjoy them, experts say, when we’re within a “protective frame” that assures us that deep down, we’re still safe.
Recent research has found certain genes(基因) which may be responsible for those of us with Type T personalities. Biochemists have separated a gene called DRD4 which seems more common in rollercoaster lovers like me.
New technologies have allowed engineers to design coasters that change speeds quickly, shoot up hundreds of feet into the air and make all sorts of twists. Research suggests that extreme fairground rides tend to appeal particularly to those of us who lead stressful, structured or controlled lives. It’s certainly true that roller coasters are a way of breaking out of the humdrum(乏味的) expectations of everyday life. Theme parks allow us to act like children again, to experience true excitement and behave a little wildly. Where else as an adult can you scream at the top of your lungs and throw your arms in the air without being sent for psychological evaluation?
If you’re looking for a great place this summer where you can get in touch with your inner risktaker, head for the nearest theme park. It’s a scream!

Even for a first-time visitor to China, it is impossible to ignore the popularity of Quick-Response (QR) codes. These square-shaped black-and-white symbols in WeChat or Alipay where QR codes are scanned to add new friends or make payments.
The QR Code system originated in Japan. The engineer Masahiro Hara felt the limitation of the one-dimension barcode in use and thus developed the QR codes which could carry data horizontally and vertically. QR codes could hold much more information than barcode due to their extra dimension. In addition, QR codes have larger data capacity, smaller print—out size and higher resistance to dirt and damage, which make them widely applied in many other applications.
Though the technology of QR codes is complicated, we can easily create our own QR codes with the help of QR code generators, many of which are available online for free. Users could enter the data they wish the QR code to display, and the generator turns it into a symbol that can be printed or displayed in electronic form. The process of creating QR codes could be really fun when we customise the design of the codes according to our specific needs. For instance, we can adjust the color, add a logo, and create social options etc. Moreover, dynamic (动态的) QR codes are also available. They are more various than standard QR codes because they allow users to edit data entered previously whereas data in standard QR codes cannot be edited once printed. Plus, don’t limit your QR code to one mobile scanner. Anyone can scan your code with any reader. A lower barrier to entry makes success more likely for you and the user.
Meanwhile, we must also recognize the vulnerability of QR codes. Due to its easy access, criminals can steal simply by replacing the QR codes with their own, routing cash into their own bank accounts. Hence, we should all become more conscious towards virtual money transactions through QR codes and participate in additional security measures.
