Supermassive black holes are much bigger—they can be billions of times the mass of our sun, Black boles of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution, said Liu Jifeng, head of the team that made the discovery. LB1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation. s a stellar black hole—the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mass of our sun because 8S these stars die, they lose most of their mass through explosions that expel matter and gas swept away by stellar windst exist.3．閱讀理解（5）考查主旨大意。根據(jù)第五段中所列的數(shù)字信息可以證明：該項(xiàng)目最近幾年在清理海洋垃圾中所做的巨大成績(jī)（已有3800噸垃圾被清理）。根據(jù)第三段中的“ More than 315billion pounds of plastic litter the world39。根據(jù)最后一段中的“ These artworks are a powerful reminder of our personal role and global responsibility in preserving biodiversity on land and in the sea.”可知這些藝術(shù)品展示了人們?cè)诤Ｑ笊锒鄻有员Ｗo(hù)中的個(gè)人作用。Working for Washed AshoreC.D.Worried.D.plastic pollution will be more serious in the oceanD.Trash left on beaches by people.C.s great gift for creating artworks.（2）According to the passage, what is the source of plastic pollution in the ocean?
