Our nearest neighbor is the moon. In the sky, the moon and the sun seem to be of the same size because the moon is much nearer.
The moon makes the tides—the changes in the level of the sea. The moon and the sun together pull the sea. In some parts of the world, the difference between * high tide' (when the sea is very near to the land) and ' low tide' (when the sea is far away from the land) is very big. This is very important for ships.
The moon is very different from the Earth. Gravity on the moon is six times weaker than that on the Earth. There isn't any air. During the day, it is very, very hot but at night it is very, very cold. Nothing can live on the moon.
If the moon goes between the Earth and the sun, we have an eclipse of the sun(日食) . The moon stops the light from the sun and we have night in the day.

It is the second-brightest object in our night sky after the moon. It is one of man's the greatest scientific achievements. It's the International Space Station (ISS) that moves around Earth.
Nov 20 is the stations’ 20th birthday. In 1998, the first piece of the ISS was sent into space. Since then, 230 people from 18 countries have visited it. Five space agencies –those of the United States, Russia, Canada, Europe and Japan- worked together to build it. Weighing about 450 tons, it contains many different parts.
Generally, the ISS holds three to six people at one time. Astronauts living there work on a variety of different science projects. The ISS has hosted over 1, 500 such projects, according to NASA(美国航空航天局) But the station's hardware is aging. In 2011, Russia announced that the ISS will be retired (退役) in 2020 in order to prevent it from becoming dangerous "space junk". However, the US later said it would use repairs to make its service life longer to 2025.
The ISS costs 21-28 billion yuan to operate each year. Many believed that this money could be better spent improving conditions on Earth. In February, US President Donald Trump announced plans to end support for the ISS by 2025. The US will use its money for other projects, like next-generation rockets and deep-space missions.
Although China is not part of the ISS program, it has helped with some of the station's experiments. China will soon have its own space station, becoming the third country after Russia and the US to do so. The station is set to be finished around 2020.

Year after year we see it up in the sky, burning brightly, giving us heat and light. The Sun certainly doesn’t seem getting old or weak. But stars do burn out and die after billions of years.

It is the second-brightest object in our night sky after the moon. It is one of man’s greatest scientific achievements. It is the International Space Station (ISS) (国际空间站) that travels around the earth.
November 20th, 2018 marks the 20th birthday of ISS. In 1998, the first piece of the station was sent into space. Since then, 230 people from 18 countries have visited it. Five space agencies (航天局)—those of the United States, Russia, Canada, Europe and Japan—worked together to build it. Weighing about 450 tons, it has many different parts in it, including labs and solar panels. Generally, the ISS holds three to six people at one time. Astronauts living there work on different science projects. The ISS has over 1,500 such projects, according to NASA.
But the station is getting old. In 2011, Russia announced that the ISS would be stopped working in 2020 in order to prevent it from becoming dangerous “space junk”. But the US later said they would repair it to make its service life longer to 2025, International Business Times reported.
The ISS costs $3-4 billion (21-28 billion yuan) each year. Many have argued that this money could be better spent improving conditions on the Earth.
Under the pressure of the public, last February, US President Donald Trump announced plans to end support for the ISS by 2025. The US will use its money for other projects, like next-generation rockets and deep-space missions, the Washington Post reported.
What will happen to the ISS after 2025 is unknown. Former astronaut Jeffrey Hoffman told NBC News, “Other ISS partners may continue scientific studies on it. Private companies might turn it into a space hotel.”
