Ⅳ.阅读理解 The world's stocks of seafood will have collapsed(暴跌) by 2050 at present rates of destruction by fishing,a scientist said.By 2048,to be exact,catches of all the presently fished seafoods will have decreased on average by more than 90 percent since 1950.The study says the loss of biodiversity(生物多样性) cut down the ability of oceans to feed the world's growing human population—expected to rise by 50 percent to nine billion in 2050. Over - fishing also destroys the stability of ocean environments largely , reducing the ocean's ability to produce seafood , resist diseases , filter( 过滤) pollutants and rebound from stresses such as climate change.And every species matters when it comes to the ocean's ability to repair itself,says the study. Dr.Boris Worm,of Dalhousie University,Nova Scotia,the lead author,said, “This is what is projected,not predicted,to happen.I am confident we will not go there because we will do something about it.But if this trend continues in this predictable fashion,as it has for the last 50 years,the world's currently fished seafoods will have reached what we define as collapse by 2048.”

“Every year a higher percentage of the currently fished stocks collapse.We are losing it piece by piece.” Prof Callum Roberts,of the University of York,who was not involved in the study,said,“The animals and plants that inhabit the sea are not merely embellishments(装饰) to be wondered at.They are essential to the health of the oceans and well-being of human society.We need to ban destructive fishing practices and create a network of large - scale marine reserves around not just Britain,but globally.” 1According to the passage that all seafood will run out in 2050 will ______. A.make the sea water much fresher and cleaner B.make it impossible to support more people with the seafood C.make the whole animals on land die away D.make the fishermen have more free time to rest 2What bad result will over-fishing bring to us? A.Destroying the stability of ocean environments. B.Largely reducing the ocean's ability to produce fresh water. C.Increasing the ocean's ability to filter pollutants. D.Making the ocean have no more capability to repair itself. 3What is Dr.Boris Worm's idea about the future of the seafood in the world? A.All seafood will surely run out in 2050. B.The seafood will become more than now in 2050. C.Seafoods will not have collapsed if people try their best to protect the ocean. D.The situation of the seafoods will get much worse than predicted even if people do something about it.

4How should we do in order to protect the seafood from running out? A.We should encourage the destructive fishing practices around the world. B.We should regard the animals and plants that inhabit the sea embellishments to be wondered at. C. We should create a network of large-range sea reserves around the whole world. D.We should learn that the animals and plants that inhabit the sea are not
