【題目】 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(美國航空航天局) 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.

本文談?wù)摿藝H空間站的一些事實(shí)。國際空間站是最偉大的科學(xué)成就之一。1998年11月20，國際空間站的第一塊被送入太空。230人訪問了那里。國際空間站一次可容納3至6人。住在那里的宇航員從事各種不同的科學(xué)項(xiàng)目。國際空間站將于2020年退役。美國將通過維修使其使用壽命延長至2025年。國際空間站每年的運(yùn)營成本為210-280億元人民幣。中國不久將擁有自己的空間站，成為第三個(gè)擁有空間站的國家。

【1】細(xì)節(jié)題。根據(jù)第2段第3句“Since then, 230 people from 18 countries have visited it.”可知自1998年以來，已經(jīng)有230人參觀過國際空間站；故選B。

【2】細(xì)節(jié)題。根據(jù)第3段中“In 2011, Russia announced that the ISS will be retired (退役) in 2020 …the US later said it would use repairs to make its service life longer to 2025.”可知“俄羅斯宣布國際空間站2020年退休，而美國說它將修理，使其服務(wù)延長至2025年”，故根據(jù)美國的說法，如果維修好了，國際空間站還要服役5年才能退役；選A。

【3】細(xì)節(jié)題。根據(jù)第四段第1句“The ISS costs 21-28 billion yuan to operate each year.”可知國際空間站每年的運(yùn)營成本為210-280億元人民幣。故選D。

【4】最佳標(biāo)題。本文談?wù)摿藝H空間站的一些事實(shí)。故這篇文章最好的標(biāo)題《國際空間站的一些事實(shí)》，選C。
