Recently, chatbot (聊天机器人) technology has gained     1     (popular) in the world of AI (人工智能). One of the most well-known chatbots     2     (call) GPT, which was developed by OpenAI. Its birth can date back to 2018,     3     the first version of GPT appeared. This version could deal with natural-sounding texts.

Over the past few years, GPT     4     (experience) several updates and improvements, making it one of the most     5     (advance) chatbots in the world. The most exciting development is its ability     6     (learn) new information. This means that as users chat with GPT, it becomes     7     (good) at understanding and responding to their needs than ever before.

    8     (look) to the future, we are confident that chatbots like GPT have the potential to change the way we live with technology. GPT has the potential to create better user experiences from customer service to education.

In all,     9     birth and development of GPT has been a milestone (里程碑) in the history of AI.     10     the continued progress of this technology, we can expect to see many exciting new developments in the years to come.

A robot has been taught to laugh at jokes to make it more human. Researchers are using AI to train robots about appropriate laughter, and     1     (distinguish)between chuckles and screams.

They described     2     (work)with a robot called Erica in the hope of making a conversation more natural. “We think that one of the important     3     (function)of conversational Al is sympathy,” said Dr Koji Inoue, a professor. “A conversation is, of course, multimodal, not just responding correctly. So we decided that one way a robot can empathize (共情)with users is to share their laughter,     4     you cannot do with a text-based chatbot.”

Creating a “     5     (share)laughter” model, the researchers used AI to help detect laughter and decide whether to laugh and what kind of laughter would be     6     (good). Four short dialogues between real people and Erica     7     (use)to test the system, which performed well.

However, the experts said there is more work to do to create     8     (true)natural laughter situations.

Dr Inoue said, “The robot should actually have     9     distinct character, and it can show this character through its conversational behaviors, such as laughing, ye gaze, gestures and speaking styles. It may well take more than 10 to 20 years before we can finally have a casual chat     10     a robot like we would with a friend.”

Diesel engines (柴油机) work on the same basic principles     1     gasoline engines, but they do the work differently. Let’s take a closer look.

The story of the diesel engine actually begins with the invention of the gasoline engine. Nikolaus August Otto     2     (invent) the gasoline engine in 1861. His invention used the four-stroke combustion (四冲程燃烧) principle, also known as the “Otto Cycle”,     3     is the basis for most car engines today. In its early stage, the gasoline engine wasn’t very efficient, and other major methods of transportation, such as the steam engine, performed     4     (poor) as well. Only about 10 percent of the fuel     5    (use) to power these types of engines actually moved a vehicle. The rest of the fuel simply produced useless heat.

Rudolf Diesel created an engine with high efficiency, and he devoted much of his time to     6     (develop) a “combustion power engine”. By 1892 Diesel had obtained a patent for     7     we now call the diesel engine.

For decades, diesel engines had a reputation for being dirty and loud. While Europe adopted the technology pretty widely, most     8    (drive) in the United States said, “No, thank you.” By the 21st century, though diesel engines became far cleaner, much     9     (quiet) and even more efficient, they experienced a setback in popular opinion because of a scandal (丑闻) in 2014. Thanks to     10     (they) proven efficiency, though, diesel engines are regaining some ground.
