girl是什么意思[2022·长春市高三模拟]The history of microbiology begins with a Dutch cloth maker named Antonie van Leeuwenhoek, a man of no formal scientific education. In the late 1,600s, 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, rainwater, 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_催眠的歌曲legacy.孙悟空卡通
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 thought it was my duty to put down my discovery on paper, so that the scientific community might be informed.”

[2022·唐山市二模]A 293millionmile journey of the NASA Perverance rover (探测器) to Mars ended successfully on February 18, 2021, with a pictureperfect landing inside the Jezero Crater. The carsized, sixwheeled rover, nicknamed Percy, is the US space agency's biggest and most advanced explorer to date. Its primary mission is to arch for signs of ancient microbial (微生物的) life on Mars.
Landing on Mars is extremely tricky. The Red Planet's gravitational (引力的) pull caus approaching spacecraft to go faster to high speeds, while its thin atmosphere—just 1 percent that of Earth's—does little to help slow it down as it approaches the surface.
The scientists had to reduce Percy's 12,000 mph speed to a safe landing speed of less than five mph—in just six and a half minutes. The target entry angle also had to be a preci 12 degrees—any steeper, and the spacecraft would burn up; any flatter, and it wo
uld get lost in space. It is no wonder that the final approach is often referred to as the 素描美女“ven minutes of terror”．
Upon attaining a manageable speed, Percy briefly flew over the Martian surface to ek out the perfect landing spot. Its complex mapreading system rapidly scanned the area and matched it with maps in its databa to find the best location.
The NASA scientists will spend the next two months testing Percy's scientific instruments. Once ready, the rover will begin to carry out its mission.
“Perverance is the smartest robot ever made, but confirming that microbial life once existed carries an unusually large burden of proof，” said Lori Glaze, director of NASA's Planetary Science Division. “While we'll learn a lot with the great instruments we have aboard the rover, it may very well require the far more wellequipped laboratories and delicate instruments back here on Earth to tell us whether our samples (样本) carry evidence that Mars once harbored life.”
