The first 【小题1】 (discover) of water on the moon was made in 2009 by India’s Chandrayaan-1 mission. The team used NASA’s Moon Mineralogy Mapper instrument to 【小题2】 (final) discover water. Since then, water has been mapped from orbit in 【小题3】 (mission) like NASA’s Lunar Reconnaissance Orbiter.

China’s Chang’e5 lunar lander used its mineralogical spectrometer (矿物学光谱仪), 【小题4】 was designed to find water. It did so by 【小题5】 (determine) spectral reflectance (光谱反射率) measurements of rocks on the moon. The water was found near the Oceanus Procellarum on the moon’s near side.

The Chang’e 5 landed on the moon on December 1, 2020 with a mission to collect lunar rocks to bring back to Earth. This is China’s first ever sample (样本) return mission;however, the country has had four 【小题6】 (success) robotic tasks to the moon before the Chang’e 5.

The lander was 【小题7】 the surface for less than 48 hours before it headed back into orbit around the moon.

China is 【小题8】 third country to bring samples back from the moon, after the United States and the Soviet Union. China is working hard to launch the Chang’e 6 in 2023. The lander is meant 【小题9】 (be)a backup to the Chang’e 5, but it 【小题10】 (head) to the lunar south pole for samples.

Tianwen I, the unmanned probe for China’s first independent Mars mission,【小题1】(land) on the Red Planet on May 2021, marking an important step in China’s exploration of the outer space. China has become the second country to land on Mars. The landing【小题2】(see) now by the world as another milestone in the development of China’s aerospace(航空航天) industry. And China’s space station core module Tianhe entered pre-set orbit in April,【小题3】marked a solid step in building the country’s first space station.

In the near future, we will be living in smart homes, which will ensure our 【小题1】 (secure), save us energy and provide a more comfortable environment to live in.

In the smart homes, 【小题2】 (use) advanced technology daily for automatic control of everything will be common. Our future home will use 【小题3】 (integrate) sensors to tell when we leave home and then go into an energy-efficient mode all by 【小题4】 (it).

We will find our dinner already prepared without turning 【小题5】 (switch) on and off ourselves. It is also amazing 【小题6】 all controls will respond to voice commands.

Smart homes can help to keep serious damage from accidents. For instance, if a water pipe 【小题7】 (start) leaking, our smart home will detect it. In addition, they can help monitor our health. They can also warn us early on if we have a critical sickness and 【小题8】 (potential) save our lives.

This smart technology isn't 【小题9】 daydream or fantasy any longer. Many new innovations have become a reality. Nevertheless, it will take a few years 【小题10】 most new homes start to use this new technology.
