Maria Garcia is 87 years old. She is now suffering from dementia(痴呆). The person she depends     1     more than anyone else in the world is her mother.

Her mother, Rosario Schielzeth, turned 104 this week. Her daughter had to     2     (remind) every few minutes of the person for     3     the birthday cake was. And Rosario didn't mind     4     (answer)every time.

“She has the     5     (patient),” says Maria's son and Rosario's grandson, Albert Garcia.

Albert, 60, describes his mother's condition as “happy dementia”, because she is never angry or upset. Like anyone     6     the disease, she can be asking the same questions over and over.

Since Rosario gave birth to Maria, the two women have almost never lived apart. When Maria     7     (get) married, she had her own home, but it was across the street. Most of her life, she and her mother have lived together.

Rosario     8     (her) has no trouble with her memory and she can remember everything     9     (clear). She doesn't wear a hearing aid. She doesn't even need     10     (glass).

Daniel Susskind has written about the threat posed by machine-learning     1     doctors, lawyers and the like in “The Future of the Professions”.

In the past, the relationship between machine and human labour     2    (drive) by two factors: the substituting effect, which caused people to lose jobs, and the improving effect, which allowed employees to do     3     work more productively.     4     author worries that, in the future, the substituting effect will dominate. Advances in AI have been so rapid that machines will eventually be better than people at most activities. A few     5    (high) paid humans will still be employed, but the rest will struggle to find work.

This     6    (depress) view of the impact of technology is possibly true. But so is a more optimistic outlook, as the economist Roger Bootle showed in “The Al Economy: Work, Wealth and Welfare in the Robot Age”,    7    (publish) last year. Mr. Bootle argued that AI and robotics would improve productivity and economic     8    (grow). As for employment, there will always be demand for services with the human touch, just as there is an appetite for homemade     9     (loaf) as well as sliced white bread.

Recently, employment has surged in both America and Britain, suggesting     10     technology has not led to widespread labour replacement.

The cost of complexity in supply chains

Adam Smith, the father of modern capitalism, famously thought that fair markets required a common moral framework between buyer and seller. That’s no surprise, considering that his ideas came out of the 18th-century marketplace, in     1     producers and consumers were likely to be neighbours. Advances in technology, transport and communications have taken us a long way since then,     2     (create) complex global supply chains. These     3     (reduce) consumer prices but introduced risks of their own, from labour exploitation and environmental degradation.

One of the costs of these supply chains has been the rise of powerful corporate middlemen between home buyers and sellers. These middlemen, including Big Tech platforms like Amazon, make it possible for us to buy goods made     4     the other side of the world, but this connective power is threatening accountability by creating so much separation between buyers and sellers     5     it’s impossible to match up with the real cost of convenience and low prices.

There are plenty of examples     6     (support) the case, from textiles made with child labour, to the unequal rents taken by middlemen in financial services or platform technology. In the latter, lack of information equality makes it difficult for market participants to have a(n)     7     (share) understanding of what is being bought and sold.

The two big questions are how to create system change and     8     will bear the cost of it. There are no simple answers to     9     of the questions, though technology offers new possibilities to connect buyers and sellers. Direct-to-consumer retailers and 3D printing, which     10    (allow) for shorter supply chains, are both examples of this, though neither currently provides anywhere near the scale to replace current systems of finance or manufacturing.

Could you imagine that    1    ( move) to a new place meant losing touch with your friends? What if    2     only way of getting news from friends was writing letters? This was what happened not so long ago. Thanks to       3    （advance) in technology, the ways of making friends and communicating with our friends have become even     4    (easy)

In the digital age, we can maintain friendships and find people with the same interests.Wherever we live, connecting with those    5     also enjoy doing the things we are fond of is very convenient.

But when you're making friends online, does    6     mean that they are really your friends? It’s hard to say. If people honestly exchange true personal information online, these friendships can be meaningful. However, people tend    7    ( post) only good things that make them appear happy and friendly. Smiling photos can hide real problems. On the Internet nobody exactly     8    (know) who you are. So we could even be sharing our information    9    criminals! Isn't it scary?

In conclusion, we must treat the Internet     10    ( wise). While technology has changed the way we are connected, our desire for friends remains the same. After all, nobody can live without friends.
