【课后任务】
信息归纳。 阅读短文，回答问题。
请阅读下面关于我国一些重大科技成就的文章，根据所提供的信息，回答后面的问题。
Big changes have taken place in science and technology in recent years. Many of these innovations(创新) have helped China catch up with other scientific powerhouses（强国）or even lead in some fields. China is among the world’s research leaders in chemistry, materials science and physics. It has also made breakthroughs in hybrid rice（杂交水稻），cloning technology, deep-sea and space exploration. Take hybrid rice as an example. Chinese agricultural scientist Yuan Longping developed the first strain(品种) in 1970 and the crop has been feeding the country since then. By the end of 2018, farmers in more than 40 countries and regions(地区) had planted more than 7 million hectares(公顷) of the crop. The Jiaolong, China’s first manned deep-sea research submersible(潜水器)，went into service in 2010. It made China the fifth country, after the United States, Russia, France and Japan, to develop deep-sea exploration technology. In space exploration, in 2018, China became the first country to send a probe(探测器) to the Moon’s far side, which always faces away from the Earth. In January,2019,Chinese scientists announced the cloning of five monkeys from a macaque(猕猴) for biomedical(生物医学的) research—the first time in the world that this had been done. Still, China needs to work harder in key technological fields such as microchip(微芯片) development and engine manufacturing(发动机制造), said Dou Xiankang, president of Wuhan University. China will first need to attract more talented researchers, according to Dou. Secondly, the government needs to offer more policy and market support, as well as invent(投资) more in human resources, to encourage innovation(创新)
1.In which aspects is China becoming one of the world’s research leaders

2.How many countries and regions had planted hybrid rice by the end of 2018

3.What’s China’s achievement in space exploration in 2018

4.What did Chinese scientists clone in January, 2019

5.What will China need to do to encourage innovation in the future
