[不定项选择题]根据下面资料,回答题
They may have lived some 1,700 years ago, but the ancient Maya had an incredible knowledge of celestial bodies, which they believed influenced everything.
Now a 15-year-old boy has studied astronomical charts devised by these ancient Mexican people, as well as satellite photos, to pinpoint the location of a forgotten Mayan city. William Gadoury, from Quebec has named the "lost city" in the Yucatan jungle K′aak Chi, or Mouth of Fire.
Satellite images suggest the lost city could be among the largest built by the ancient civilisation, which thrived between 300 and 700 A
D.
Wondering why the ancient people built their cities far away from rivers and in inhospitable mountains prompted the teenager to look to the sky for answers. Incredibly, the brightest of the stars matched the largest cities.
"I was really surprised and excited when I realised that the most brilliant stars of the constellations matched the largest Maya cities." He told The Journal of Montreal.
He is said to be the first to make the connection, which could lead to further finds.
It was in the 23rd constellation, containing three stars, that he found two matching cities on the map, suggesting one has not yet been re-discovered.
To investigate further, he used satellite images from the Canadian Space Agency and Google Earth to search the dense jungle for any signs of buildings.
The photographs revealed linear features that "stuck out," Daniel De Lisle, from the Canadian Space Agency told The Independent.
"There are linear features that would suggest there is something underneath that big canopy," he said. Armand La Rocque, from the University of New Brunswick believes one of the images shows network of streets leading to a large square, which may be a pyramid. "A square is not natural, it is mostly artificial and can hardly be attributed to natural phenomena," he said.
It′s possible 30 buildings accompany an impressive pyramid at the site. If true, the lost city would be one of the five largest known to archaeologists, built by the Mayans.
Linking the position of stars and the location of a lost city and the use of satellite images on a tiny territory to identify the remains buried under dense vegetation, is quite exceptional.
Dr. La Rocque thinks William Gadoury′s technique could lead archaeologists to pinpointing the location of more possible lost Mayan metropolises.
It can be learned from the passage that the newly-found Maya city was ___________.查看材料
A.found in a jungle
B.built along rivers 1,700 years ago
C.built far away from rivers 300 years ago

[填空题]They were, by far, the largest and most distant objects that scientists had ever detected: a strip of enormous cosmic cloud some 15 billion light-years from earth. 71. But even more important, it was the farthest that scientists had been able to look into the past, for what they were seeing were the patterns and structures that existed 15 billion years ago. That was just about the moment that the universe was born. What the researchers found was at once both amazing and expected: the US National Aeronautics and Space Administration’’s Cosmic Background Explorer satellite―Cobe―had discovered landmark evidence that the universe did in fact begin with the primeval explosion that has become known as the Big Bang (the theory that the universe originated in an explosion from a single mass of energy).
72. The existence of the giant clouds was virtually required for the Big Bang, first put forward in the 1920s,to maintain its reign as the dominant explanation of the cosmos. According to the
