Question

【題目】In 1985, a lionfish was caught off the coast of Florida. Now they can be found not only in the Atlantic Ocean but also in the Gulf of Mexico and the Caribbean Sea. And they are continuing to move south. Lionfish are native to the Indian and western Pacific Oceans. So how did they end up in the Atlantic? Scientists believe some pet owners abandoned their unwanted lionfish and poured them into the sea. Little did they know the trouble their actions would cause.

The Atlantic Ocean turned out to be a comfortable home for lionfish. Their venomous spines (毒刺) protect them from sharks and other fish. Female lionfish can spawn (產(chǎn)卵) every few days, producing as many as 2 million eggs per year. Other big fish would have competed with lionfish for food. But overfishing has removed many of these large fish. As a result, the fish have eaten so much that they have grown to be more than three times the size of their cousins in the Pacific and Indian Oceans. “They eat mostly fish,” says Stephanie Green, a scientist at Oregon State University.

All that eating has caused great changes. Scientists have found that when lionfish are present somewhere, many other fish, which are small enough for them to eat, disappear. Some of the fish they eat are greatly missed in their habitats. For example, parrotfish eat certain plants off corals (珊瑚), which allows corals to grow better. But they are now disappearing due to lionfish.

Scientists say lionfish are here to stay. But there are ways to deal with the problem. The key, says Green, is to keep lionfish numbers in check. In Florida, divers can now go through a special training program and get certified (授予合格證書) to catch lionfish in areas where fishing is not usually allowed. And a number of restaurants have added the fish to the menu. “It’s going to be a long-term battle, but the missing sea species will come back someday,” says Green.

Answer 1

【答案】

【1】A

【2】D

【3】B

【解析】

試題分析： 本文介紹殺傷力很強的獅子魚。Stephanie Green認為正在消失的海洋物種總有一天會回來，她對與獅子魚的斗爭充滿希望。

【1】A細節(jié)理解題。根據(jù)第二段中“Female lionfish can spawn(產(chǎn)卵) every few days, producing as many as 2 million eggs per year.”可知，這種魚繁殖很快。故知A項正確。 根據(jù)第二段中“As a result, the fish have eaten so much that they have grown to be more than three times the size of their cousins in the Pacific Oceans.”可知，B項錯誤。根據(jù)第二段中第二句話可知，獅子魚不吃鯊魚，故C項錯誤。根據(jù)第一段中第一句話可知，D項錯誤。

【2】D推理判斷題。根據(jù)第三段的內(nèi)容可知，作者拿鸚鵡魚為例來說明獅子魚的殺傷力有多強。故選D。

【3】B觀點態(tài)度題。根據(jù)最后一段中最后一句話可知，Stephanie Green認為正在消失的海洋物種總有一天會回來，由此可得知她對與獅子魚的斗爭充滿希望。故選B。
