to four billion tons of methane(甲烷) gas could be under icecovered areas of antarctica(南极洲).and they say if enough ice melts(融化),it is possible that the gas could run out and add to the warming of earths air.jemima wadham of bristol university in britain directed the study.she says the amount of methane gas recorded is more than ten times the amount of that in the arctic(北极).sandra arndt,who teaches in utrecht university in the netherlands,also works on the study and she says the high pressure and cold temperatures under the ice make good conditions for forming methane hydrate(水合物),which is like ice.the scientists say the methane gas came from a period thirtyfive million years ago when antarctica was much warmer than today and contained a small amount of life forms.researcher slawek tulaczyk of the university of california at santa barbara describes how the methane gas formed：some of the life forms fell to the bottom,then these sediments were cut off from the rest of the world when the ice grew and buried below.earlier this year,methane gas was also found in the opposite end of the world.researchers found thousands of places in the arctic where methane gas was rising to the surface.they found one hundred and fifty thousand seeps(渗出口)places in alaska and greenland where methane gas had escaped.euan nisbet,who researches the methane gas,from the university of london,describes the arctic area as the fastestwarming area on earth.he says the area has many methane sources that will increase as the temperature rises.he says there is a serious concern that the warming could cause more warming.and the news of finding methane gas in antarctic adds to his worry as the ice top of antarctic is melting at a high speed.1.how much methane gas could be under the arctic areas in jemimas opinion?a.about four billion tons.b.less than forty billion tons.c.about four million tons.d.less than four hundred million tons.2.according to the scientists,thirtyfive million years ago_.a.there were some life forms in antarcticab.antarctica was rich in lifec.antarctica was as cold as todayd.antarctica was covered with ice and snow3.what does the underlined word “sediments” in paragraph 2 probably mean?a.something that is lost forever.b.something that is new and important.c.something that falls to the bottom.d.something that can produce energy.4.we can learn from the passage that_.a.jemima wadham and sandra arndt work in the same universityb.one hundred and fifty thousand seeps were found in antarcticac.the cold temperatures help to form methane gas in antarcticad.whether exploring the methane gas in antarctic is under
