Technological innovation（创新）may not give you a warm feeling. 【小题1】 Messaging apps are examples of technology that is helping bring people together. It’s ready to continue improving our lives as innovation allows technology to really understand how we live.

【小题2】

Some of the most popular and widely adopted innovations make things we’re already doing easier. A well-designed piece of technology can transform something that consumes time into a worry-free touch of your finger, giving you more time to spend with friends and family.

Developers keep finding new and brilliant ways to prove our identities online. With fingerprints and voice recognition, technology keeps getting better at proving we are who we say we are. 【小题3】 .The more trust we have, the easier it will be to fully welcome the aspects of fintech（金融科技）and have control of our financial data.

Crowdfunding（众筹）technology keeps breaking down walls that may have previously kept good ideas from being realized. Here’s how it works: You throw your project to people through an online platform. 【小题4】 . By connecting dreamers and inventors to a new type of capital, technology is giving more creative ideas the opportunity to become a reality.

As technology continues improving, it becomes easier to build and keep a connection with someone who isn’t in the same location as you. 【小题5】 . And think about how great it will be when you can communicate with your friends and relatives in virtual reality. It will be the next best thing to be together in person.

   Humans have been keeping animals as pets for tens of thousands of years, but Dr Jean-Loup Rault, an animal scientist at the University of Melbourne in Australia, believes new companions are coming: robot pets.

“Technology is moving very fast,” Rault told ABC News, “The Tamagotchi in the early 1990s was really the first robotic pet, and now Sony and other big companies have improved them a lot.”

This may not sit well with pet lovers. After all, who would choose a plastic toy over a lovely puppy? But Rault argues that the robotic kind has a lot going for it: “You don’t have to feed it, you don’t have to walk it, it won’t make a mess in your house, and you can go on a holiday without feeling guilty.” The technology also benefits those who are allergic to pets, short on space, or fearful of real animals.

It’s not clear whether robot pets can replace real ones. But studies do suggest that we can bond with these smart machines. People give their cars names and kids give their toy animals life stories. It’s the same with robots. When Sony stopped its repair service for its robot dog Aibo in March 2014, owners in Japan held funerals.

As an animal welfare researcher, Rault is concerned about how robotic pets could affect our attitudes towards live animals. “If we become used to a robotic companion that doesn’t need food, water or exercises, perhaps it will change how humans care about other living beings,” he said.

So are dogs and cats a thing of the past, as Rault predicts? For those who grew up with living and breathing pets, the mechanical kind might not do. But for our next generation who are in constant touch with smart technology, a future in which lovely pets needn’t have a heartbeat might not be a far-fetched dream.

   What makes us human？Is it our thoughts？Our emotions？Our behavior？

All of these things make us who we are，but at the center of it all lies the genome — the genes inside our bodies that determine everything from our hair color to our intelligence. But if we could change our genome，would we still be human？

Recently，a group of scientists from the US and South Korea worked together to successfully“edit”a human embryo（胚胎）and remove a genetic mutation（变异）that would have led to heart disease. This was achieved with the help of CRISPR-a gene — editing tool that allows scientists to edit the genome by cutting，changing or adding to parts of it.

Scientists involved in DNA editing are certain about the good of their work，and hope that in the future，diseases could simply be“edited out”.

However，others aren't so sure. People are worried that the science could be used not only to remove life-threatening illness，but also to make a“perfect”baby whose DNA has been chosen to improve its intelligence or other qualities. They say that this is a shallow way of thinking about raising children.

“It makes you think about who we are as people，and it makes you ask if humans should use the kind of power…that is changing human evolution（进化），”Jennifer Doudna of the University of California said.

Still，others worry that DNA editing could be turned into an expensive service that would only be available to the people who could afford it. That might mean the rich would be given another advantage in a world where they already have plenty of them.

“You could find wealthy parents buying the technology for their children, leading to even greater inequality than we already live with,”Marcy Darnovsky, director of the San Francisco Center for Genetics and Society, said.

   Onions make you cry, add flavor to food and win popularity for their medicinal benefits. Now the vegetable has another use—_____ green energy.

Anew system debuts（首次亮相）on Friday that _____ onion juice into electricity at Gills Onions, the largest fresh onion processor in the United States.

The Oxnard, California-based company _____ its new onion-fueled power to reduce its electric bill by $700,000 a year and _____ its annual greenhouse gas emissions by up to 30,000 tons.

The _____ ending to this green energy tale, however, started with another question: how to _____ onion waste.

“_____ we peel an onion, 35 to 40 percent of the onion comes off before we have a(n)_____ onion. That's the top, tail and skin around the onion, and _____ we can get to the meat,” said Steven Gill, co-owner of the 25-year-old company.

They used to pull the waste to the fields for compost（混合肥料）, but that turned out to be a tough ______. Ten years ago, Gill started looking at technology for a(n) _____, including microturbines（微型燃气轮机）.

“We ______ cutting the skins into pieces and extracting all the ______, which is very high in sugars, and bacteria love that stuff,” Gill said.

In the new system, bacteria ______ methane（甲烷）gas from the juice. The gas then goes to two 300 kilowatt fuel cells, creating ______ power for 460 homes. If everything goes smoothly, ______ are that the company will get 35 to 40 percent of its electricity from the on-site generator.

The company ______ $ 9. 5 million in the project and will receive $2. 7 million from Southern California Gas Co. _____ cutting its electric bill, the company will save $400,000 in costs and expects paybacks in the new future.

The onion grower now has a new ______: to be a zero-waste facility in the coming decade.

“We want to ______ it all the way through and make the full circle,” Gill said.

   Technology has enabled people to connect fast and across vast distances. 【小题1】 Therefore, it is important to find ways to communicate better, while we are still keeping pace with the demands of the modern day.

Cut back on texting. Texting is a good way of keeping in touch and communicating with another person if calling him is not possible. Unless you can’t help it, give up the habit of texting — while walking, eating or driving — because texting is not real communication. 【小题2】 Calling is a great way of enhancing conversations because it’s more direct, with a greater chance of successful communication.

【小题3】 We are more willing to spend time on Facebook than actually leave our desks and have a conversation with the person working right next to us. A good way of improving real-life communication is to log off or keep yourself away from social media.

Meet people face-to-face. The next time you want to open Facebook to chat with a friend, call him up and meet him instead. 【小题4】 Take time to meet the person who matters to you and you will get a kind of communication and relationship that staring at a screen just can’t provide.

Technology is a tool. It is worth remembering that technology is only a tool we have. 【小题5】Use social networks to find people, to reconnect with friends, to support a cause and to contribute to the bigger picture in a more real manner.
