The Advantages of Non-cash Payments

With the widespread use of non-cash payments，we don't need to carry a purse or cash at all．Therefore，never will we worry about getting fake notes or having to count our change．Plus，there are often discounts if you make non-cash payments，as major online payment platforms are competing to attract more consumers．
Non-cash payments have greatly changed people's lives in China．Personally，I think non-cash payments should be encouraged．

On Monday，truck driver Justin Martin from Ontario，Canada，was passing through Ohio．When he stopped that evening in Circleville，the stop，which was normally a busy town，was extremely quiet．Only a few other trucks were parked，and all the restaurants looked closed—except for one．
There was a Wendy's (like McDonald's，but smaller) with a few cars in the parking lot，so，left with no other choice，Martin decided to walk over and see if it was still open．The dining room was closed．However，an employee did open the drive-in window to talk to him and let him know they were closed and had just thrown away all the leftover food．Martin said thanks，and was most likely facing a night with no hot food．But the employee had a thought and told him to hang on a moment．
She went and got the manager，19-year-old Ohioan Zach Meadows．When Meadows heard about Martin's trouble and what he wanted，he went to speak to Martin himself．“We have actually been closed for about five to ten minutes，” Meadows said．He approached the window and began talking to the man，and then he found out that he was a truck driver．“Could you do me a favor Because I haven't really eaten all day，” Martin asked．“Could you give me a second，and do you want something to drink？” Meadows answered without
thinking．Martin told Meadows that he wanted some iced Coke，but Meadows gave him a large one and some foods since he had been driving for eight or nine hours that day．He just wanted to do what he could to help Martin．Although Martin tried to pay for the meal，Meadows refused to accept his money．Meadows told him，“It's free for us，so it should be free for you．”
There was only one problem：Meadows was breaking the rules by giving Martin the food free of charge．But at that moment，he decided that helping out a trucker in these difficult times was more important than following general rules．
注意：1．续写词数应为 150 左右；

[参考范文]
Martin ended up with a variety of foods and a large Coke．Touched by the kindness of the Circleville Wendy's，he filmed a video once he got back to his truck，publicly thanking the young manager and two employees．Once this video got out，Ohioans were really proud of Zach．They were so proud that a truck driver got treated that way by an Ohioan．To them，Zach is the perfect example of an Ohioan，who love their state and have a lot of pride in who they are when they represent their state．
The video started spreading，and it wasn't long before it got back to Meadows． “When I woke up the next morning，I had all these text messages，including the vice-president of Wendy's；all my fellow managers congratulating me，” he said．“It was humbling for sure．At noon the next day the video had about 75，000 views．” Zach said，“I don't want to turn anyone away from not eating，no matter who they are or what they do．” Martin hopes that all the attention his video is getting benefits Meadows，and Meadows hopes that more people will be inspired “to do nice things for the people around them．”

1 / 6课时分层作业(十二)
Ⅰ．阅读理解
A
Last year as I faced my 33rd birthday，it seemed like a good time to sit down and make a list of financial goals．Some were instantly doable，like spending less on food．(Goodbye，$7 organic strawberries．) Others were more ambitious：save enough cash for a down payment on an apartment；build a savings account for fun grown-up stuff like buying last-minute plane tickets to Tahoe．
The problem：These things required more money than I was making．The other problem：In this economy，it wasn't realistic to expect a huge raise．Suddenly，my future started to look like an ever-narrowing tunnel．Without a big increase in cash flow，how was my amazing life supposed to start Obviously，I was doomed．
I loved my job，I loved my boss，but I'd spent my 20s closing up shop at the office every night when I knew I should have been playing harder and taking more risks．I'd built a career I was proud of，but realized I couldn't view a paycheck as my final reward．
Finally，I made a decision．I'd give myself a happiness raise and bring into my life more of the good things that money can't buy (and that I'd been denying myself)，and less of the stuff that didn't have much real value．
The first step was to do a serious accounting，calculating where I'd been spending my time and energy and noting how much joy I was netting on a daily basis．The results didn't surprise me：so many have-tos and must-dos，so few moments of real enjoyment．
I set a new rule：Anytime the word “should” flashed across my mind，I hit the brakes．Did I really want to attend this baby shower or join that book club Often I didn't—so I respectfully said no，and found that the world didn't end．
1．Why did the writer say goodbye to $7 organic strawberries
A．He was on a diet．
B．He couldn't afford them．
C．He didn't like them any more．
D．He planned to cut down the food expense．
2．What was the difficulty with the writer's ambitious financial goals
A．He was making little money．
B．It was difficult for him to get promoted．
C．He couldn't save more money for his amazing life．
D．His future seemed like a ever-narrowing tunnel．
3．According to the passage，which can give the writer more happiness
A．Joining a book club．
B．Attending a baby shower．
C．Buying last-minute plane tickets．
D．Spending the weekends with his loved family．
4．What can we infer from the passage
A．Birthday is a good time to set a goal．
B．We need to learn to say no to something．
C．The author celebrated his birthday by making financial goals．
D．The author decided to make more money for his amazing life．
B
Researchers have recently discovered that gut bacteria (肠道细菌) that grow within our body help the brain build important social skills．
According to a paper published in PLOS Biology in November，zebra fish were used as research subjects to test how a lack of bacteria could affect social skills．Zebra fish are social animals as even 2-week-old fish start to hang out in groups of four to twelve．
The experiment started with making a group of fish “bacteria-free” through their diet．The other group were injected with a healthy mix of gut bacteria after they were hatched．About 15 days later，the second group began swimming in groups while the “bacteria-free” group “shockingly，didn't，” Judith Eisen, a co-author of the new research，said to Quanta Magazine．
The team then examined the fish's brains，discovering obvious differences between the two groups．The ones who lacked the gut bacteria had more interconnections among the neurons (神经元) in their brains in charge of social behavior，and social neurons were seen to have overgrown．This made the fish more cautious in social situations．
Scientists said that the bacteria might release a special chemical that crosses the blood-brain barrier to reach the brain directly．Although the experiments were only on fish，the findings can theoretically be applied to humans．The team wishes to explore how gut bacteria affect the human brain in the future，which may lead to solutions to mental health problems．
Perhaps many people who claim that they have “social phobia (社交恐惧症)” can blame their guts．However，social phobia，or social anxiety disorder，can be a serious illness if overlooked．According to the National Health Service in the UK，it is more than shyness but instead a constant fear of social situations．Patients may experience panic attacks which are an overwhelming fear and anxiety that last for a few minutes．
5．What does the research focus on
A．The growth of gut bacteria．
B．The way zebra fish build social skills．
C．The influencing factors of social behavior．
D．The link between gut bacteria and social behavior．
6．What was found in the experiment
A．The two groups of zebra fish became different in size．
B．The bacteria-free zebra fish swam in groups．
C．The zebra fish injected with gut bacteria were quieter．
D．The zebra fish with gut bacteria swam in groups．
7．How do scientists feel about their findings
A．Positive． B．Disappointed．
C．Doubtful． D．Concerned．
8．Which is TRUE about “social phobia” according to the last paragraph
A．It will result in gut problems．
B．It is a severe illness．
C．It may cause panic．
D．It is all about shyness．

The Artificial Intelligence(AI) era has quietly come．On the one hand，AI can help us to finish some tedious and repetitive tasks．On the other hand，it also brings us some worries．For example，AI may replace human labor in some fields，leading to unemployment．
In my opinion，we should make full use of the advantages of AI and try to reduce its disadvantages．We should also pay attention to the development of AI and make sure it is used in a reasonable way．Only in this way can we make the most of AI and benefit from it．
Ⅰ．[语篇解读] 本文是一篇记叙文。作者33岁时，反思自己的生活用度，发现问题后决定给生活做减法，把更多金钱买不到的好东西带进自己的生活。
1．D [细节理解题。根据第一段中的“Some were instantly doable，like spending less on food．(Goodbye，$7 organic strawberries．)”可知，作者对7美元的有机草莓说再见，是因为作者计划削减食品开支。故选D项。]
2．C [细节理解题。根据第二段的内容可知，由于多种原因，作者再也攒不出更多的钱来过他那令人惊叹的生活，这是作者要实现雄心勃勃的财务目标而面对的困难。故选C项。]
3．D [推理判断题。根据第四段中的“I'd give myself a happiness raise and bring into my life more of the good things that money can't buy”可知，作者要把更多金钱买不到的好东西带进自己的生活让自己幸福，D项“与他所爱的家人共度周末”是金钱买不到的幸福。故选D项。]
4．B [推理判断题。根据第四段和最后一段的内容可知，作者要把更多金钱买不到的好东西带进自己的生活让自己幸福，所以作者开始说“不”，由此可得出要想生活幸福，就要学会对生活中不必要的事情说“不”。故选B项。]
【语篇解读】 本文是一篇说明文。研究人员最近发现，在我们体内生长的肠道细菌有助于大脑形成重要的社交技能。
5．D [细节理解题。根据第二段中的“According to a paper published in PLOS Biology in November，zebra fish were used as research subjects to test how a lack of bacteria could affect social skills．(根据11月发表在《公共科学图书馆·生物学》上的一篇论文，研究人员以斑马鱼为研究对象，来测试缺乏细菌如何影响社交技能。)”可知，这项研究的重点是肠道细菌和社会行为之间的联系。故选D。]
6．D [细节理解题。根据第三段中的“About 15 days later，the second group began swimming in groups while the ‘bacteria-free’ group ‘shockingly，didn't，’ Judith Eisen，a co-author of the new research，said to Quanta Magazine．(大约15天后，第二组开始成群游泳，而‘无菌’组‘令人震惊的是，没有，’新研究的合著者朱迪思·艾森对《广达杂志》说。)”可知，带有肠道细菌的斑马鱼成群游动。故选D。]
7．A [推理判断题。根据倒数第二段中的“Although the experiments were only on fish，the findings can theoretically be applied to humans．(虽然这些实验只是在鱼身上进行的，但是这些发现在理论上可以应用到人类身上。)”可推知，科学家们对这项研究的发现是持积极态度的。故选A。]
8．C [细节理解题。根据最后一段中的“Patients may experience panic attacks which are an overwhelming fear and anxiety that last for a few minutes．(患者可能会经历惊恐发作，这是一个压倒性的恐惧和焦虑，持续几分钟。)”可知，“社交恐惧症”可能会引起患者惊恐。故选C。]
