It can take a little imagination to see how some innovations might change an economy. Not so with the latest Al tools. It is easy — from a writer’s perspective, uncomfortably so — 【小题1】(think) of contexts in which something like ChatGPT, a clever chatbot which【小题2】(take) the web by storm since its release in November 2022, could either dramatically boost a human worker’s productivity or replace them outright. The ChatGPT in its name stands for “generative pre-trained transformer”, 【小题3】 is a particular kind of language model.

【小题4】(feed) huge amounts of human-created text, ChatGPT looks for statistical regularities in this data, learns what words and phrases 【小题5】(associate)with others and therefore predict what words should come next in any given sentence and 【小题6】 sentences fit together. The result is a machine that can persuasively mimic (模仿) human language.

This capacity 【小题7】 mimicry allows ChatGPT to write essays and poetry, think up jokes, formulate code, and answer questions whether to a child or an expert. Its performance is so astonishing 【小题8】 many over the past months have been both celebrating and panicking. “Essays are dead,” wrote the cognitive scientist Tim Kietzmann. Others claim that it will finish off Google as a search engine. And the program 【小题9】 thinks it may be able to replace humans in jobs from insurance agent to court reporter.

Nevertheless, there is an 【小题10】(underlie) problem that faces any form of artificial intelligence. A computer manipulates (处理) symbols. Its program specifies a set of rules with which to transform one string of symbols into another, or to recognize statistical patterns. But it does not specify what those symbols or patterns mean. To a computer, meaning is irrelevant ChatGPT ”knows" what appears meaningful to humans, but not what is meaningful to itself

The successful launch of the probe（探测器）Tianwen l on Thursday in Wenchang, South China's Hainan province, marks the 【小题1】 (begin) of the country's efforts to find out more about Mars.

The probe will travel about seven months【小题2】 it reaches Mars, where it will place a rover（火星车）to wander around the surface. The rover, which has yet to be named, is l.85 meters tall and 【小题3】 (weigh) about 240 kilograms. It has six wheels and four solar panels and will be able to move 【小题4】 a speed of 200 meters per hour on Mars. The rover carries six

【小题5】 (science)instruments including a multispectral camera, subsurface penetrating radar and a meteorological measuring device. It will use the instruments 【小题6】 (examine) Mars' surface compositions, geological structures, environment and possibly water.

The vehicle 【小题7】 (expect) to operate for about three months on 【小题8】planet. It is of great significance to humankind's exploration of outer space. If the 【小题9】 (high) autonomous machine works well, it will become the world's fifth operational Mars rover, 【小题10】 (follow) the previous four from the United States.

This year marks 【小题1】 20th anniversary of China’s first manned space mission(任务)that sent astronaut Yang Liwei on a 21-hour journey around Earth in the Shenzhou V spacecraft. As one of the 【小题2】(nation) in the world able to independently finish manned space missions, China 【小题3】(carry) out 12 manned flights since then.

A special committee was formed in August 1992 and it 【小题4】(decide) that China would use manned spacecraft to build a space station in the coming years. The plan was passed in September that year, 【小题5】(mark) the first official manned space program of the nation. 【小题6】(achieve) the goal, scientists made specific plans and took practical steps, advancing slowly from multi-day flights 【小题7】 month-long missions. Thanks to years of efforts, we are proud that our country completed the Tiangong space station last year. Orbiting Earth about 400 kilometers above the ground, Tiangong has both a core module 【小题8】two science facilities, which is 【小题9】(regular) connected to several visiting spaceships.

Chinese researchers are designing a new-generation manned spacecraft, 【小题10】 will be significant in the nation’s first manned exploration to the moon around 2030.
