- **B) called**:过去分词表被动,“被称作”,正确表达“particles被命名为molecules”的事实,符合被动语义。- **C) being called**:现在分词被动进行态,强调动作正在进行,但此处为普遍科学事实,无需进行时态,语法冗余。- **D) have called**:完成时主动态,无法作定语且主语需为主动执行者,与“particles”...
外文素材选自Highlights for Children天空为什么是蓝色的Earth's air is made mostly of nitrogen and oxygen mole-cules(氮氧分子)and tiny particles(粒子). In 1871, Lord Rayleigh realized that when light strikes(击中)particles that are so small, some of the light scatters(散射) off in石噬中老交流...
Inhalation is the process of breathing in air. This takes air and molecules in the air from outside the body into the lungs. IN the lungs necessary gas exchange is performed. Where oxygen from the environment is transported to the blood and carbon dioxide generated as a waste product from ...

Last time we finished going over some of the fundamental concepts of nanotechnology, the multi-disciplinary science of manipulating or controlling extremely small units of matter on the scale of molecules or even atoms. 教授:好。上次,我们完成了纳米技术一些基本概念的学习,纳米技术是一门交叉科学,是在...
"Sodium tetraborate (borax) is perfectly safe when used as directed, and it's one of the only chemicals known to link together long chains of glue molecules to make the traditional glue-based slime. "After unverified news articles were released in 2017 vilifying borax, leading glue ...
It is all about how different materials are put together and made up of atoms and molecules. Additionally, chemistry is how these materials act under different conditions. Slime is a non-Newtonian fluid. A non-Newtonian fluid is neither liquid nor a solid. It can be picked up like a solid...
