 台湾籍旅美老师今天交给我们的句子是:


As altitude increases, atmospheric 1 pressure decreases. This is due to Earth's gravitational pull on the air molecules 3 in the atmosphere. The closer to the Earth's surface the stronger the force exerted on these molecules.


随着高度上升,大气压力就会降低。这是因为地球对于大气中的空气分子有地球吸引力的关系。越接近地球表面,这些分子便会承受越强大的引力。
学习重点:
1.atmospheric 大气(层)的、富有情调的
atmospheric (adj.) 大气(层)的、富有情调的
atmosphere (n.) 大气、气氛
2.gravitational 万有引力的
gravitational (adj.) 万有引力的
gravitation (n.) 引力、吸引
gravity (n.) 万有引力、严重性
3.molecule 2 分子
molecule (n.) 分子
molecular 4 (adj.) 分子的
biology (n.) 生物学
biography (n.) 传记
4.exert 运用、行使 (权威、权力等)
exert (v.) 运用、行使 (权威、权力等)
exertion 5 (n.) 努力、行使
exert yourself (phr.) 努力

adj.大气的,空气的;大气层的;大气所引起的
  • Sea surface temperatures and atmospheric circulation are strongly coupled.海洋表面温度与大气环流是密切相关的。
  • Clouds return radiant energy to the surface primarily via the atmospheric window.云主要通过大气窗区向地表辐射能量。
n.分子,克分子
  • A molecule of water is made up of two atoms of hygrogen and one atom of oxygen.一个水分子是由P妈̬f婘̬ 妈̬成的。
  • This gives us the structural formula of the molecule.这种方式给出了分子的结构式。
分子( molecule的名词复数 )
  • The structure of molecules can be seen under an electron microscope. 分子的结构可在电子显微镜下观察到。
  • Inside the reactor the large molecules are cracked into smaller molecules. 在反应堆里,大分子裂变为小分子。
adj.分子的;克分子的
  • The research will provide direct insight into molecular mechanisms.这项研究将使人能够直接地了解分子的机理。
  • For the pressure to become zero, molecular bombardment must cease.当压强趋近于零时,分子的碰撞就停止了。
n.尽力,努力
  • We were sweating profusely from the exertion of moving the furniture.我们搬动家具大费气力,累得大汗淋漓。
  • She was hot and breathless from the exertion of cycling uphill.由于用力骑车爬坡,她浑身发热。
