二、語法填空

• 11．Scientists often compare coral reefs to underwater rainforests，yet unlike the leafy plant base of a forest，corals are animals.The soft organs inside the hard parts of corals are naturally transparent and get （1）

  （they） famously brilliant color from algae（藻類）living inside them.
      When corals experience stress from hot temperatures or（2）

  （pollute），they end their interdependent relationship with this algae，typically forcing them out（3）

  turning white，though one recent study indicates some corals turn a bright neon color when stressed.Corals are still alive when they bleach（白化），but they're （4）

  risk-essentially immunocompromised（免疫功能低下）-and many （5）

  （eventual） starve and die，turning a dark brown.
      People first noticed coral bleaching events in the 1980s.The problem worsened in 2016，when an El Nino weather pattern，（6）

  causes warmer waters in the Pacific Ocean， （7）

  （mix） with an already unseasonably warm ocean and killed off a third of the corals on the Great Barrier Reef.Since then，roughly half the corals on Australia's famous reefs （8）

  （die） in following bleaching events，risking an underwater landscape 1，500 miles long.
      Scientists around the world are looking for all kinds of ways to protect and maybe even revive corals.One option is （9）

  （create） more marine protected areas-essentially national parks in the ocean.Scientists say creating marine shelter，where fishing，mining，and recreating are off limits，makes the reefs （10）

  （healthy），and so much stronger.

三、閱讀理解

• 12．Chinese astronauts conducted a science lecture to millions of students on Dec.9，2021 from the Tiangong space station.The three astronauts，Zhai Zhigang，Wang Yaping and Ye Guangfu，showed life in space and conducted experiments in microgravity.
     It was the first lecture of the Tiangong Class，China's first extraterrestrial （地球外的） lecture series.Its goal is to popularize space science.
     "The laboratory of the space station has many conditions that the Earth laboratory does not have，such as the environment of weightlessness and radiation，" said Wen Xin，a professor at Nanjing University of Aeronautics and Astronautics.He said that important jobs for astronauts in the space station include cell observation and maintaining plant life.
     In the lecture，Ye demonstrated experiments related to cell growth in a weightless environment.He compared the growth and shape of cells in artificial gravity and zero-gravity to study their changing principles in space.
     Another experiment in the space lecture was shown by Wang Yaping.She illustrated how a paper flower "bloomed" on the surface of water in Tiangong space station.She explained that the surface tension of water is magnified （放大） in space due to zero gravity.
     One of the examples of surface tension on Earth is that some insects can "walk" on water.They use surface tension to "stand" instead of falling through water.
     Surface tension plays a key role in product development.Researchers around the world are measuring surface tension to improve the quality of their products，according to Biolin Scientific，a science company.Paints are tailored to stick better on the surfaces they are applied to.Surface tension also has impacts in drug development.
     Although the astronauts are thousands of miles away，their research does influence our life.Shi Yi，a teacher at the Beijing No.101 Middle School，told China Daily that the space lecture was "an eye-opening experience that would arouse students' interest in science".
  
  （1）What makes the space laboratory special？

  
  A．It is operated by a professor.
  B．It has a unique experiment environment.
  C．It broadcasts experiments to students.
  D．It promotes cell growth.
  （2）What can we learn through Ye's cell experiment in space？

  
  A．The rules of cell growth.
  B．The secret in a weightless environment.
  C．The conditions of cell growth.
  D．The differences between the universe and the earth.
  （3）What can we say about surface tension？

  
  A．It can speed up flower blooming.
  B．It is related to product quality.
  C．Paints have an influence on it.
  D．Drugs are used to measure it.
  （4）Which of the following is the best title of the passage？

  
  A．Special Laboratory Environments.
  B．Examples of Surface Tension.
  C．Learning from Space.
  D．Lectures about Cells.
