Question

Imagine looking out of your window and seeing a whale swim by.That's the sight that surprises New York City residents recently.In the past years,humpback whales have been spotted in the two rivers surrounding the island of Manhattan,the Hudson River and the East River.1.

Experts say that river cleanup efforts have improved water quality and led to an increase in the number of fish there.Fish are on the humpback's menu.2.The sighting is also an encouraging sign that conservation efforts are helping humpback whales come back.In 1973,the species was listed as the endangered.Now scientists say humpback whales are making a comeback.

By the middle of the 20^th century,hunting whales for profit had nearly wiped out many whale species.In 1973, the U.S. set up the Endangered Species Act.People were no longer allowed to hunt them in the U.S. waters.In 1982, the International Whaling is illegal worldwide.3.Last September,it was announced that nine groups of humpback whales are no longer endangered.Four groups are still endangered and a fifth is threatened.

4.The number of them is growing particularly faster in the Southern Hemisphere like Tasman Sea and Coral Sea.And the number of humpback whales in Hawaii has made an amazing recovery.In 1966,there were fewer than 1,500 humpbacks there.Today there are about 10,000.But humpbacks in other parts of the world are still struggling.

5.“We still have a lot of work to do,”says Angela Somma,head of NOAAS Fisheries’ endangered Species division.“But with the right protection,the number of humpback whales should continue to grow.

A.Those efforts to save whales are paying off.

B.People are frightened when seeing whales in the river.

【解析】本文首先向我们展示了鲸鱼数量回升的好现象，接着又讲述了鲸鱼由于被捕濒临灭绝的历史以及人们为了保护鲸鱼所作出的努力，最后告诉我们鲸鱼数量的现状以及我们仍需做的努力。

1.根据空格前一句“In the past years, humpback whales have been spotted in the two rivers surrounding the island of Manhattan, the Hudson River and the East River,”，在过去的几年里，在两条环绕曼哈顿岛，哈得孙河和东河的两条河流里，已经发现了驼背鲸鱼，而选项C中“Last year, one even swam past where the mayor lives.”，去年，有一只甚至从市长住的地方游过，在意思上正好与其相承接，故选C.

2.根据空格前一句“Fish are on the humpback's menu.”，增加的鱼成了驼背鲸鱼的菜单，而选项E中“The extra food in the rivers is mainly what’s attracting the whales.”，河中额外的食物是吸引鲸鱼的主要东西，这里“额外的食物”就是“增加的鱼”，故选E.

3.空格前讲的都是人们为保护鲸鱼所作出的努力，空格后“Last September, it was announced that nine groups of humpback whales are no longer endangered.”，去年九月宣布九组鲸鱼不再处于濒临灭绝的境地，故选A.

4.根据空格后“The number of them…”,可知空格里应该填鲸鱼的数量，故选D.

5.根据空格后““We still have a lot of work to do,”’,说明对鲸鱼的保护工作目前做的还不够，而选项G“Scientists say that the focus needs to be on the whales that are still struggling.”，科学家们说注意力需要放在那些仍然处在困境中的鲸鱼们，在意思上正好相承接，故选G.
