Recently Google has announced a series of new artificial intelligence (AI) (人工智能) tools designed to help users in organizing emails and creating business writings and meetings. These tools display important AI development progress in recent years. The tools are built by putting a great d【小题1】 of data (数据) into machine learning computer systems. The data trains the AI systems to develop skills and produce human-like results.

The technology received w【小题2】 attention last year after a company called Open AI announced a free writing tool called Chat GPT. That tool can quickly produce human-quality writings. Experts (专家) say s【小题3】 systems may bring great changes to many different industries and jobs. Now some companies are a【小题4】 to test Google’s new tools in their development and business activities.

Like Chat GPT, Google’s AI tools are designed to create completely written texts f【小题5】 many different purposes. For example, an office worker could enter some keywords of a kind of text they want. The tools could then create a full marketing email, training materials or a business plan in a while. Google sees the system being able to o【小题6】 an “AI Helper” to help human workers in real time. Google wants to have its AI change the work of lawyers, scientists, teachers and more.

However, Google says it keeps developing AI products of high quality. That is why the company is inviting groups of “trusted testers” to use its AI tools r【小题7】 than widely selling its new products. Google’s new AI tools are the company’s l【小题8】 move to fight for business. Companies l【小题9】 Microsoft and Meta are also working on products about AI.

Technology experts have w【小题10】 that while the new AI tools can produce human-like writings, the systems can also make mistakes. Last month, Bard, Google’s new AI tool designed to give a better online search, made a mistake and caused a $100-billion drop. Microsoft users said the company’s new AI tools produced unfriendly and rude results.

Libraries give kids a quiet and safe place to read and to learn. For more than 100 years, libraries have p【小题1】 an important role in Americans’ education. But how are these book-filled buildings changing with the times? You may be surprised to find out.

Benjamin Franklin famously founded America’s first lending library in 1731. But the public library system got its biggest development in the American history in the late 1800s. Businessman Andrew Carnegie d【小题2】 millions of dollars to help build free public libraries across the country.

Between 1886 and 1919, Carnegie’s donations helped build 1, 679 new libraries.

Carnegie believed in the chances that libraries could o【小题3】 the chances to Americans, young and old. He knew that the more libraries there were, the more people would have access to books, lectures, news and more.

Chances are that there is a p【小题4】 library in or near your community. You can easily find one close to your home. After all, the United States has 9, 225 public libraries. Today, libraries keep growing. Seven out of ten libraries have free Internet. This opens many doors for people who cannot go online at home, including the opportunity to apply for jobs online.

Libraries are also teaching kids about the fun of reading. The new program! Read! Build! Play! adds reading into playtime: As kids listen to a book being read a【小题5】, they use Legos (乐高积木) to build images from the story h【小题6】: Today’s libraries are always looking for creative programs to bring people into the library.

Benjamin Franklin once said, “The doors of wisdom are never shut.” As long as the doors or public libraries are open, what he said is most certainly correct!
