Sometimes it’s hard to imagine how a new technology will affect your life. Nobody thought that 10 years after getting the internet in their homes, they’d be online everywhere and all the time with smart phones. Have a look and get prepared for what’s coming.

Hyperautomation (超级自动化)

Hyperautomation is the combination of machine learning software and automation tools to do work. What does hyperautomation look like? With hyperautomation, the coffeemaker is involved in every step of the process. It uses machine learning to know how much coffee you like to make, what time you like to make it, and how often. It orders more beans for you --your favorite brand - when the amount gets low. It also coordinates(协作)with your dishwasher to make sure your favorite cup is clean and ready. The social robot market is expected to be worth $19 billion by the end of 2025. By then, each home could have robots that rival the intelligence of science fiction’s most beloved droids (机器人),like Star Wars，C-3PO.

Practical Blockchain

Organizations should begin evaluating blockchain (区块链)，which has the potential to change industries . It can provide trust and value exchange throughout society.

Aside from its possible use as a currency, blockchain can also be used to track real-world items. For example, contaminated (被污染的)food - especially vegetables - can be traced back to its date and place of packaging.

There are also so-called “smart” contracts. These are simple programs written into the blockchain. With these, events can trigger actions. For example, if you order from Taobao, your payment is held until the delivery guy marks your shipment “completed”. Then payment is immediately received by the seller. Similarly, a student’s university allowance could be limited by a parent to only be spent on necessary things .

1.What do we know about hyperautomation?

A.It is by nature a computer program. B.It is mainly used in the kitchen.

C.It makes robots in science fiction a reality. D.It has huge commercial potential.

2.How does the author illustrate blockchain?

A.By making comparisons. B.By giving examples.

C.By explaining the process. D.By stating arguments.

3.What benefit can blockchain bring us?

A.Computer programs can be made simpler.

B.The money you pay can directly go to the seller.

C.A revolution in industries may take place.

D.Polluted vegetables will no longer exist.

4.What is the best title for the text?

Sometimes we may find that every week there are a lot of new stories about how climate change is affecting the planet, or new plans to battle its effects like the one announced by President Barack Obama the other day. But the concept itself isn't new at all --- in fact, scientists have been exploring questions about climate change for almost 200 year.

The idea of “greenhouse gases” goes back to 1824, when Joseph Fourier wondered what was regulating the earth's temperature. Fourier concluded that the atmosphere must be responsible for containing the heat absorbed from the sun and described it as a box with a glass lid: As light shines through the glass, the inside gets warmer as the lid traps the heat. As Fourier's ideas spread, it came to be called “the greenhouse effect”.

Scientists continued to study the greenhouse effect. Until a Swedish chemist named Svante Arrhenius came along, scientists understood how global warming actually works. After years of work, Arrhenius determined that the level of carbon dioxide in the atmosphere did in fact have a direct effect on global temperatures.

Arrhenius found that CO2, and other gases trap radiation, which warms the atmosphere. Arrhenius was the first to suspect that burning coal could contribute to the greenhouse effect. But Arrhenius welcomed the warming effect on the planet. At a lecture later that year, Arrhenius noted that creatures of a warmer earth “might live under a milder sky and in less barren surroundings”.

While Arrhenius' findings won him the 1903 Nobel Prize in chemistry, scientists kept debating whether the greenhouse effect was increasing until 1950, when researchers finally began to find strong data supporting it. By the end of the 1950s, American scientists had been sounding the alarm on the long-term consequences of climate change. Climate change research has come a long way since Fourier first described the greenhouse effect – still, maybe Arrhenius should have been more careful of what he wished for.

1.What can we know from Paragraph 1?

A. Climate change has caused terrible disasters.

B. The topic of climate change has been talked a lot.

C. Scientists should work harder to research climate change.

D. The whole world should cooperate to protect the environment.

2.What does the underlined word “it” in Paragraph 2 refer to?

A. The atmosphere.

B. The idea.

C. The earth.

D. The earth's temperature.

3.What's the main idea of Paragraph 3?

A. Serious consequences of climate change.

B. The history of studying the greenhouse effect.

C. Significant research findings about climate change.

D. Scientists' doubts about the cause of global warming.

4.What did Arr henius think of the greenhouse effect?

A. It was beneficial for creatures on the earth.

B. It was totally responsible for climate change

C. It brought more troubles than benefits to human beings.

D. It worked as a punishment for human harmful activities.

5.What's the author's attitude towards Arr henius' expectation?

高三英语单项填空中等难度题查看答案及解析

When Gitanjali Rao shared how she likes “finding solutions to real problems”, it was hard to imagine this dynamic 11-year-old girl could settle a problem that has escaped scientists for years.

In just three months, Rao came up with a device（装置）that can replace the costly and lengthy tests currently used to reliably determine lead levels in our fresh water. Inspired by the current litigation （诉讼）in Flint, Michigan, a case of water pollution from 2014 to 2015, Rao designed a new testing system that resulted in her being named America’s Top Young Scientist for 2017.

Rao had been following the water problem for about two years. She was amazed by the number of people affected by lead pollution in water and wanted to do something to change this. Gitanjali spent months trying to convince local high schools and colleges to give her lab time to continue her experiment. At home, Gitanjali worked on her project in the “science room” she asked her parents to create for her. Rao has created a device that uses three parts: a cartridge, a Bluetooth reader and an app. To put it simply, the cartridge contains carbon nanotubes（纳米管） that react to lead. This reaction is then registered by the Bluetooth reader, which sends a signal to a mobile app that can tell you immediately if your water is safe to drink.

Rao appropriately named the device Tethys after the Greek goddess of fresh water, and is hoping to make a little improvement to get the device on the market. While we may not be aware of any lead pollution present in our aging pipelines, lead poisoning can cause delays in physical and mental development. With Rao believing that the “purpose of science is to make a difference”, her incredible invention could make a difference to millions of people in the United States.

1.What do we know about Rao’s device?

A. It’s cheap and quick.

B. It’s cheap and inaccurate.

C. It’s expensive and reliable.

D. It’s portable and time-consuming.

2.What made Rao have the idea of designing the device?

A. Her parents’ suggestions.

B. The name of the Greek goddess.

C. Her interest in settling real problems.

D. The water pollution litigation in Flint.

3.What do the carbon nanotubes function as?

A. Sending immediate signals.

B. Recording the reaction results.

C. Detecting the presence of lead.

D. Showing the water quality results.

4.What does the author think of Rao’s invention?

A. It will lead Rao to make a fortune.

B. It will help millions of Americans drink safe water.

C. It will promote the development of science in America.

D. It will soon settle the lead-polluted problem thoroughly.

It’s been said that life turns on small things. Sometimes it’s hard to see how small choices can change your life. But when put together over time, the little things can make the biggest difference.

The theme of Success for Teens is “Little Things Matter”. The book helps teens identify small,positive choices they can make in their lives to help them reach their goals. Lots of teens don’t realize how the little choices in their lives can have lasting effects. Often they focus on the bigger events, such as a major exam, a big game or competition, or choosing a college. The little things, however, can go unnoticed unless your teen understands how important they can be.

The little things that lead to success are mostly easy to do. Help your teen identify a few areas in everyday life where he or she can make small, positive choices. It might be as simple as getting up on time, prioritizing(按重要性排列) their schoolwork, putting in an extra 10 minutes of practice or using some spare time to help someone else.

When the season was over, he had an empty three hours a day, so he started spending one third of such extra time daily looking for ways to help other kids. Over the past few years, his project has raised thousands of dollars to help abused, homeless and sick children. Kyle spent just a little time each day doing something that ended up benefiting a lot of kids. The important thing to understand is that Kyle made the small and positive decisions necessary for success. Make sure your child understands that even though the results of the positive choices may not be seen right away, they are building on each other and taking him or her on a path that will lead to success.
