Do you use a calendar to help you organize your life？ By listing what you need to do on any special day，you can make sure to keep all for your appointments and not worry whether you've forgotten something．Calendars are also useful for reminding（提醒） people what day a certain holiday is on and what days you might have off from work． Besides， they are used for planning fun things like vacations and outings．
A calendar is usually divided into twelve parts， and each one stands for a month with all the days laid out
in a grid﹣like（网格状的） form． A block of space usually is for one day， and there is enough space for you to write down what you need to do on that certain day． You probably use all different kinds of calendars． A calendar on your cell phone screen is easy to use， and so is a large paper calendar that hangs on your wall．

I have read plenty of articles about self﹣improvement these past few months， and most of them tell you that you need to wake up and keep positive（积极的）． When you wake up， you need to think that something great is going to happen today， and that you are going to have a great day． This kind of positive attitude（态度） is supposed to change your whole day．
So this morning I woke up and decided to give it a whirl． The sun was shining brightly through my bedroom window， and it immediately gave me this warm feeling inside． I thought to myself， "Today is going to be a great day． One of the best days ever!" I got out of bed， took my morning shower and began to get dressed． I put on a pair of dress pants I have not warned in a while， followed by my dress shirt and that is when it began． I reached into my left pocket and pulled out what felt like some paper．
You know that feeling of finding a 20 bill in your pants and it feels like free money？Because you forgot all about it and thought you never did？
I pulled out a 100 bill and a 50 bill in the same pocket．It seemed like the best thing that had happened to me these days．Yes，150 starts off my day! I'm sure if someone could have seen the smile on my face， they would have understood， I shouted in joy， with my poor dog looking at me like I was crazy!
Start your morning off thinking you are going to have the best day ever and you just might! I really want to know what will happen next．

In our culture， the ability to make one's own decisions is important． John F． Kennedy's quote（引语）"Too often we enjoy the comfort of opinion without the discomfort of thought．" shows an unpleasant truth．
Much of what we know and believe has been taught to us by others， and we often accept this information without spending much time thinking it over for ourselves．
In today's world， we are being presented with information， ideas and beliefs， but many of them are against each other． Psychology（心理学）tells us that if we hear an idea enough times， or if it comes from someone we respect（尊敬）， we will probably believe that idea． In these cases， we base our opinions on the opinions of others． If each of us does not think about this information for ourselves and come to our own conclusions ， we will become nothing more than parrots（鹦鹉） quoting the opinions of others．
Examples of spreading fake news without thought can be seen on the Internet． Some people believe whatever they read and then share the story without thinking about the facts． All it takes is one quick click（点击）of the "share" button， and the story travels on its way to influence even more unthinking readers． This can cause serious problems．
If we just stop for a moment to think about what we read and hear， and form our own opinions， we will be more thoughtful， more independent， and more creative people， but few take that time． Yet we need not lose heart over this bad habit． In fact， simply becoming aware （意识到） of it is the first step towards correcting it． Once we become aware that we tend（趋向）to hold opinions and beliefs without thinking them through， we can change that pattern of behavior． Hopefully， we can learn to experience and enjoy the "discomfort of thought" and form our own opinions．
（1）What's the purpose of this passage？
A． To describe how Internet news spreads．

Artificial intelligence （AI） （人工智能）is the ability of a computer program or a machine to think and learn． It is also a field of study that tries to make computers "smart"． John McCarthy， a scientist， came up with the name "artificial intelligence" in 1955． Many things such as learning and problem solving can be done by computers， though not in the same way as we do．
An unusual goal of AI research is to create computer programs that can learn， solve problems， and think logically（逻辑地）． At present we use the term AI for successfully understanding human speech， recognizing（识别）human faces， operating self﹣driving cars and competing in some game systems like Chess and AlphaGo（阿尔法狗）． Some people also consider AI a danger to humans if it develops too quickly． Professor Stephen Hawking （霍金）， a well﹣known British scientist， was not for this kind of technology．
Math is the basic language of AI． If we raise the standard in the learning of math， our students will be more likely to become successful AI designers in the future． We not only want bright students， but also need to attract average students and give them the math skills which are needed to change them into AI designers． Besides， a good knowledge of computer science is also necessary for AI designing．
Scientists hope to create creative and emotional AI which can possibly understand human feelings or create art． Many ways and tools have been tried to discover this fascinating field．
（1）From Paragraph 1， we know that ．
A． all problems can be solved by AI
B． machines with AI can think and learn
C． AI has been around for only 60 years
D． AI works in the same way as humans
（2）The underlined word "it" in Paragraph 2 refers to（指的是） ．

D． AI
（3）According to the writer and the following school report， which student will most probably become a successful AI designer？
