阅读理解
Space is a vast and mysterious place that has always fascinated humans. In recent decades, we have made great progress in space exploration. One of the most significant achievements is the International Space Station (ISS). It is a large spacecraft that orbits the Earth and serves as a home and workplace for astronauts from different countries.
The ISS allows scientists to conduct a variety of experiments in space. These experiments help us understand more about the human body, the environment, and technology in space. For example, studies on how astronauts' bodies change in microgravity have led to important medical discoveries.
Moreover, space exploration has also led to the development of new technologies that benefit our daily lives. Satellites, for instance, provide us with communication, navigation, and weather forecasting services.
However, space exploration is not without challenges. The cost of building and operating spacecraft is extremely high. Additionally, space travel poses risks to astronauts' health and safety.
Despite these challenges, the pursuit of knowledge and the desire to explore the unknown continue to drive us forward. We can expect even more remarkable achievements in space exploration in the future.
1.What is the ISS
A. A small satellite.
B. A large spacecraft that orbits the Earth.
C. A space telescope.
D. A space museum.
2.Why is the ISS important
A. Because it only provides a place for astronauts to live.
B. Because it allows scientists to conduct experiments.
C. Because it is very expensive.
D. Because it is easy to build.
3.What benefits do satellites bring to our daily lives
A. Only communication services.
B. Only navigation services.
C. Only weather forecasting services.
