Numerous scientific innovations that enjoyed their heyday in history were later【C2】______ by new ones. Today, although we still admire those inventors, we are not awe-struck (惊叹的) by their innovations or inventions as we now boast of science and technology much more【C3】______ than in the past.
Will the science and technology of our times【C4】______ forever?【C5】______. In the future, people will view today’s science and technology just as we【C6】______ those of centuries ago.
Therefore, technicians and scientists ought to【C7】______ full play to their innovations during the latter’s limited "shelf life."【C8】______, the application and spread of advanced science and technology has been hitting man-made snags (障碍) in today’s world. Many of these【C9】______ are imposed by the developed West.
Science and technology is a【C10】______ that belongs to all mankind. To prevent its spread and exchange of scientific data for the sake of narrow interests is a selfish act.
The International Space Station, a manned space laboratory that saw the first launch in 1998, will complete its【C11】______ in 2020 and then go out of orbit, falling into the sea. By then, China will have established its own space station,【C12】______ will be the only one of its kind in space at that time. China has expressed its【C13】______ to share the space station with the rest of the world. But if U.S. politicians continue【C14】______ their obstruction, it will be impossible for U.S. aerospace workers to use the Chinese space station.

Both China and the United States are frontrunners in 5G technology. U.S. telecom companies and consumers have a【C17】______ demand for Huawei’s 5G equipment but have been blocked access because of U.S. politicians’ focus on their own interests. However, 5G is not the end of communication technology. In the near future, quite possibly, it will be replaced by quantum communication technology. The space station technology of today will also be replaced by new ones. One day in future, human beings【C18】______ be able to undertake interplanetary journeys as easily as they travel by plane from one country to another. Focusing on immediate interests and【C19】______ a blind eye to the future will hamper science workers’ efforts to maximize the benefits of science and technology and will also affect entire society.

选项
A、currently
B、certainly
C、continuously

语境推理。通读整段可知此话是本段的中心句,此句意为“5G通信技术(5G)是目前世界上最先进的技术”。词义辨析:currently目前地,certainly毫无疑问地,continuously继续地,officially正式地,故只有A选项符合题意。
