Passage （A）
From radiocarbon dating in the 1940s to remote nsing techniques (RST) in the 1960s, archaeologists have long been early urs of technology. Now, experts can u robots to explore ancient cities underwater. Imaging technologies can show the true colors of ancient statues, and protein analysis tells us what dias ancient people had. Here are three more of the main tech tools ud in archaeology.
LiDAR
Ancient sites and buildings may be hidden under trees, water, soil and other things, making them difficult to find for archaeologists. However, with Light Detection and Ranging (LiDAR), archaeologists can scan different areas and find previously hidden sites. It works by nding lar puls and receiving data from the surface below. The data can then help produce a 3D image of a buried city. In the early 2010s, archaeologists ud LiDAR to find a lost Mayan city of which there ud to be little evidence.

Virtual reality
Rebuilding ancient sites is an important part of archaeology. But it's never an easy job, as the original materials are hard to find, and rebuilding may also cau harm to the site. VR technology helps to bring old sites back to life. For example, British archaeologist Morgan rebuilt a Neolithic (新石器时代的) site in Turkey with VR. She collected data from the site and “rebuilt” the site brick by brick on a computer. Then by wearing a VR headt, she “w
alked around” the site. “It allowed me to look at the site in ways I’ve never done before,” she told Slate, an online magazine.

Artificial intelligence
There are many mysterious words on the oracle bones(甲骨) of the Shang Dynasty that take a lot of time for archaeologists to understand. AI can help with this. By quickly analyzing a huge amount of data, AI can find patterns and learn to “read” the words.

Passage （B）
The history of microbiology begins with a Dutch cloth maker named Antoni van Leeuwenhoek,a man of no formal scientific education. In the late 1600s, Leeuwenhoek, inspired by the magnifying lens(放大镜) he ud to examine cloth, built some of the first microscopes. He developed a technique to improve the quality of tiny, rounded lens, some of which could magnify an object up to 270 times.After removing some plaque from between his teeth and examining it under a lens, Leeuwenhoek found tiny twisting creatures, Which he called"animalcules"".
His obrvations, which he reported to the Royal Society of London, are among the first descriptions of microbes(微生物), Leeuwenhoek discovered an entire univer invisible to
the human eye. He found different microbes in samples of pond water, rain water, and human blood. He gave the first description of red blood cells, obrved plant tissue, examined muscle, and investigated the life cycle of incts.
Nearly two hundred years later, Leeuwenhoek's discovery of microbes helped French chemist and biologist Louis Pasteur to develop his"theory of dia". This concept suggested that dia originates from tiny organisms attacking and weakening the body. Pasteur’s theory later helped doctors to fight infectious dias including anthrax, diphtheria, polio, smallpox, tetanus, and typhoid. All the breakthroughs were the result of Leeuwenhoek's original work. Leeuwenhoek did not foree this legacy.
In a 1716 letter, he described his contribution to science this way: "My work, which I’ve done for a long time, was not pursued in order to gain the prai I now enjoy, but chiefly from a strong desire for knowledge, which I notice resides in me more than in most other men, And therefore,whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, so that the scientific community might be informed thereof.”
