A real friend is someone who, walks in when the rest of the world walks out. A real friend is someone     1     support we can count on. Yet these days, the modern tools that keep us     2    (connect) are eating away at the meaning of friendship. Social media like blogs has come between us and the friends whom we love. We may be able to make many friends online,     3     these friendships can be quite shallow.     4    (make) friends a real part of our lives, we should put down our smartphones and meet them in person.

Hannah Taylor is a schoolgirl from Manitoba, Canada. One day, when she was five years old, she was walking with her mother in downtown Winnipeg. They saw a man eating out of a garbage can (垃圾箱) placed by the street. She felt quite surprised and couldn’t help     1     (make) an enquiry of why he did that. Her mother said that the man was badly off, homeless and hungry.     2     (explain) well, the case could be understood by Hannah. Hannah was very upset, full of anxiety and thought to herself, “He     3     be living a hard life.” Later, when Hannah attended school, she saw another homeless person. It was a woman, pushing an old shopping trolley (购物车) which was piled with bags. It seemed that everything the woman owned was in them.     4     of the two persons were so impressive for her.

Hannah began to speak out about the homelessness in Manitoba and then in other provinces. She meant     5     (get) her message of hope and awareness understood by as many people as possible. She started the Ladybug Foundation, an organization whose real motivation was to get rid of (摆脱) homelessness. She began to host “Big Bosses” lunches, at which she would try to persuade local business leaders to make a     6     (contribute) to the cause.

There is an emergency shelter in Winnipeg called “Hannah s Place”, something that Hannah is very proud of. Hannah’s Place divided into several areas, provides shelter for people when it is so cold that sleeping outdoors can mean death. In the past five years since Hannah began her activities, a lot of praise     7     (receive) by her. She was     8     (devote) to many of such kinds of activities. She received the 2016 BRICK Award recognizing the efforts of young people to change the world. She must have done quite well in the past few years.

Hannah stands     9     an examples of young people who are making a difference in the world now and who think     10     (positive) they should be responsible for helping people in need.

The other day I     1    (drive) by an apartment when a lady blocked my way. I pulled over,     2    (ask) if she needed a ride somewhere. She told me “no” and then asked me if I needed a microwave.

I said “no” and asked why. She told me she had one for sale     3     just five dollars.     4    (curious) drove me to find out what her situation was. I asked her to let me see it. The microwave,     5    looked new, was worth a lot more than five dollars. I asked her what she needed the money for.

What she said broke my heart. She said she wanted to buy bananas and bread for her kids but all she had was this microwave. I told her I would buy it     6    (late), for I needed to go to the bank     7    (withdraw) some money. I rushed to the grocery store and bought her bananas and bread.

When I returned to her apartment I gave her the     8    (grocery) and the extra twenty dollars in cash. I told her to keep her microwave and asked her if she needed anything else. She was so     9    (thank) to me that words failed her. She’s gone now     10     she brought me such joy.

At Lowe's, the home improvement chain, a "LoweBot” in some stores can answer simple questions, such as where     1     (find) items, and can assist with inventory(库存)monitoring. These robots free up workers from routine tasks, thus     2    (give) humans more time for customer interaction-but that's only the beginning.

The real benefit of retail robots is the opportunity to capture the exact data about the products on the     3    (shelf) and customer buying patterns, which can increase efficiency and accuracy in inventory management. The key is using retail robots as data - collectors within     4    Internet-of-Things (loT) , which is best thought of     5     a complex network of connected devices, objects, and sensors gathering data that     6    (analyze) in the cloud or with edge computing.

With robots in stores, retailers already have the beginnings of a whole IoT     7    (solve).

As the robots move around the stores, they take photos of every shelf and aisle (过道)，which are then digitized and converted into metrics and insights about out - of - stock merchandise and pricing.

Such detailed data is     8    (incredible) valuable in retail,    9     understanding and anticipating consumer demand is necessary. For example, Stitch Fix, which provides just - for - you clothing choices to shoppers at home, regards     10     (it) as its business model, from product recommendation to inventory management and fashion design.

What is the most popular communication tool today?     1     your answer is QQ or MSN, I must say you’re a bit old-fashioned. Today, a new form of communication “WeChat”, which     2    (own) a Chinese name Weixin, is becoming the most influential text and voicing tool all over the world.

What advantages does WeChat have? First, Wechat is     3    relatively cheap way of communication because It uses network traffic instead of telephone fare. Next, we can know     4    is going on at any time. And we can have     5    (easy) access to information available than other messaging tools.

What roles does it play     6     our daily life? According to the latest report, the registered users on Wechat platform have topped 200 million and Wechat     7    (expand) its business to overseas market. Can you imagine that a mobile phone “app” is so     8    (appeal) that it reaches 200 million users within 8 months? Wechat itself has become the most popular mobile chat application in the world. A large number of people have become “WeChataholic”, which means they keep     9    (stare) at the mobile phone all the time and can’t live without it.

However, while enjoying its great convenience, people should not ignore the danger of     10    (cheat), for information on Wechat is publicly known.

People in China are now increasingly paying with their cell phones. According to the statistics, Chinese     1    (spend) $5.5 trillion through mobile payment platforms last year, about 50 times the amount in America.

Mobile Payment apps, Alipay and WeChat Pay,     2     belong to the country’s leading social messaging platforms, together hold 90 percent of the market,     3    (leave) Apple Pay struggling to make inroads (进军市场).

I have recently spent a day in Hangzhou, home     4     Alibaba, to see how easy it was to go cashless, and I found     5     somewhat ahead of other cities, including Beijing. I rode buses and subways, which all accept Alipay. I visited a major Buddhist temple, where visitors can make     6    (donation) with their phones.

Mobile Payments     7    (great) improve transactional (交易的) efficiency. When doing business, people don’t have to worry about getting fake money,     8     having to carry change.

All this is a rapid and somewhat     9    (surprise) development in a country where,     10     couple of decades ago, it wasn’t even clear that credit cards were going to catch on.
