Greenland is the biggest island in the world. And the ice sheet that sits atop it is massive. “The pile of ice being so thick, it extends more than 10, 000 feet above the ocean. And if all that ice were to melt and go into the ocean, global sea levels would rise by 24 feet everywhere around the world,” said Jason Briner, a geologist at the University at Buffalo. The ice sheet is melting, of course. But just how much, compared to the past?

Briner’s team did a com puter simulation（模拟)of the southwest of the Greenland ice sheet, which he says is a good proxy for ice melt across the entire ice sheet. The researchers plugged past climate data into that model to “hindcast”, rather than forecast, the past activity of the ice sheet. They then checked the model’s predictions of the past shape and size of

the ice sheet by looking at piles of rocks and dirt on Greenland today, which outline the edges of ancient ice. And the simulation was in good agreement with the actual situation.

Using that reconstruction of the ice sheet over time, the team could compare the ice sheet’s historic losses to those happening today under human-caused global warming. And they determined that Greenland is on track to lose more ice this century than during any century in the past 12, 000 years — possibly four times as much. The results appear in the journal Nature.

Ultimately it’s up to us how much ice actually melts. “Hu manity has the button — the carbon button — and that button is going to influence the rates of ice loss from the Greenland ice sheet.” If the world goes net carbon zero by 2100, for example, Briner says ice loss could stop, entirely at the end of the centu ry, according to one model. “That was what kept me from being compl etely depressed about our study. ” Dozens of countries have already announced goals to go net carbon zero by the middle of this century — so far the U. S. is not one of them.

1．What does th e underlined word “proxy” in Paragraph 2 refer to?

A．Combination. B．Example. C．Recommendation. D．Interpretation.

2．What do we learn from the computer simulation done by Briner’s team?

A．It is conducted by predicting the activity of the ice sheet.

B．It centers on ice melt throughout the entire ice sheet.

C．It shows the ice sheet’s losses are in decline.

D．It consists with the ice sheet’s actual circumstance.

3．Which of the following can be the best title for the passage?

A．Greenland Is Melting Faster

B．Global Sea Levels Are Rising

C．America Causes the Ice Sheet to Melt

D．Man Can Conquer Nature

这是一篇说明文。讲述了一项研究：纽约州立大学水牛城分校的地质学家布里纳的团队通过对格陵兰冰原西南部进行了一次计算机模拟发现，格陵兰岛在本世纪将失去的冰比过去12000年的任何一个世纪都要多，可能是过去的四倍。说明了格陵兰正在加速融化。1．

词句猜测题。根据上文中“Briner’s team did a computer simulation(模拟)of the southwest of the Greenland ic e sheet, ”（Briner的团队做了一个格陵兰冰原冰盖西南部的计算机模拟），可以推测,划线部分所在句子是指“这是对整个冰盖融化的一个很好的诠释/解释”，划线词与选项D Interpretation.“解释”意思相近。故选D。

2．

推理判断题。根据第二段最后一句“And the simulation was in good agreement with the actual situation.”（仿真结果与实际情况吻合较好。）可知，这与冰原的实际情况相符，故选D。

3．

主旨大意题。结合文章第二段中“Briner’s te am did a computer simulation（模拟）of the southwest of the Greenland ice sheet, which he says is a good proxy for ice melt across the entire ice sheet. ”（布里纳的团队做了一个格陵兰冰原冰盖西南部的计算机模拟，他说这是整个冰盖融化的很好的诠释。）及第二段最后一句“And the simulation was in good agreem ent with the actual situation.”（模拟结果与实际情况吻合）；第三段中“And they determined that Greenland is on track to lose more ice this century than during any century in
