The key facts of news story 1.
Time : 27 June 2012
Achievement: China became the fifth country to send a manned submarine into the deep sea.
Name of the submarine: Jiaolong
Activities: collected samples and conducted research
Future development: The submarine will be used for a deep-water survey of the Pacific, Atlantic and Indian Oceans.
Sample summary
On 27 June 2012, China became the fifth country to send the Jiaolong to a depth of 7,062 metres in the Pacific Ocean’s Mariana Trench, with three men in it. While there, they collected samples and conducted research. In the future, this 8-metre-long submarine will be used for a deep-water survey of the Pacific, Atlantic, and Indian Oceans.
The key facts of news story 2.
Time : 3 May 2017
Achievement: Pan Jianwei and his colleagues had created the world’s first quantum computing machine.
Participants: Pan Jianwei and his colleagues
Function: The new computer can process data 24,000 times quicker than regular computers.
Future development: It may take another ten to twenty years to create a fully functioning quantum computer.
Sample summary
