问题   There are three countries that have sent spacecraft to the moon, the U.S., Russia and the third which soft landed a rover there back in 2013 is China. But China hopes to become the first country to explore the dark side of the moon or the far side. The part never faces Earth. China has a mission plan this year, though a launch date hasn’t been announced yet. One problem with exploring the dark side of the moon is that there’s no easy way to communicate with whatever kind of vehicle people put there. The moon itself would block any signals coming from Earth. So to address that, China launched a satellite earlier this year that will hang out in the moon’s orbit acting like a relay station between the Earth and the new rover that China’s planning to send to the moon later this year. The country is a relatively late entry into space exploration. China didn’t send its first satellite into orbit until 1970. But over recent decades, it’s funneled billions of dollars into space research. It’s hoping to ultimately set up a base on the moon that’s run by robots. And it’s also setting its sights on Mars. China is hoping to send some spacecrafts there starting in 2020.
When did China launch the first satellite?

选项 A、Earlier this year.
B、In 1950.
C、In 2013.
D、In 1970.

答案D

解析 细节题。题干:中国何时发射了第一颗卫星?根据题干关键词China,the first satellite 定位到“China didn’t send its first satellite into orbit until 1970.(中国直到1970年才将第一颗卫星送入太空轨道)”,由此可知D项“在1970年”符合文意。A项“今年早些时候”,根据文章中提到的“China launched a satellite earlier this year…”可知,今年早些时候中国发射了一颗卫星,但并不是第一颗卫星,故排除。C项“在2013年”,根据文章首句“…the third which soft landed a rover there back in 2013 is China”,可知中国是于2013年把月球探测车软着陆在月球上,并不是发射卫星,故排除。B项“在1950年”在文中没有提及,故排除。故本题选D。
