17．Form July to October every year，about a quarter of the world's blue whales feed in the Pacific Ocean off the coast of California．But the whales now face a major threat in their favorite feeding area．Lots of ships carrying cargo sail in the same area at the same time．All too often，a ship will hit a whale．
According to a new study，this problem has become a serious threat to the whole population of the world's blue whales．Ther e are only about 10，000 of the creatures in the world．
Blue whales are the largest known animals ever to live on Earth．But if hit by a container（集装箱） ship，a blue whale will likely die from its injuries．
In 2007 alone，large ships killed five blue whales in the waters off San Francisco and Los Angeles，California．The National Oceanic and Atmospheric Administration （NOAA） says that because there are so few whales already，losing three to five from the California whale population every year is a great loss．
"The population of blue whales in this part of the Pacific is about 2，500，"says Sean Hastings，a member of NOAA．"So every whale counts toward this population moving off the endangered-species list．"
Now，one very simple program is already under way in the Santa Barbara Channel，a waterway that separates mainland California from the nearby Channel Islands．The Channel Islands National Marine Sanctuary has asked large container ships passing through the area to slow down．Sailing slower will allow the ship's members more time to look at detection（探测） equipment and-more important-to change course before hitting a whale．
Several of the world's largest shipping lines are set to take part in the new program．For every ship that passes through the Santa Barbara Channel at or below the reduced speed of 12 knots（a measure of speed in water），the company that owns the ship will be paid $2，500．
25．The underlined part"this problem"in Paragraph 2 refers to the fact thatA．
A．whales are hit by ships
B．whales lose their way
C．whales travel too far
D．whales can't find enough food
26．What can we learn about blue whales？C
A．They like following container ships．
B．They mainly live in the pacific Ocean．
C．They are in danger of disappearing．
D．They were once large in number．
27．The purpose of the simple program mentioned in Paragraph 6 is toD．
A．ship the whales
B．guide the whales
C．look for the whales
D．protect the whales
28．The text is most probablyB．
A．a travel guide
B．a newspaper report
C．an advertisement
D．a research paper．

分析本文讲述了蓝鲸的生存现状，由于生存受到威胁，相关部门制定了许多保护蓝鲸的措施．

解答 25．A，推理判断题，根据上一段提到All too often，a ship will hit a whale，可知"这个问题"指的就是船撞到蓝鲸的事情，故答案为A．
26．C，推理判断题，根据句子Ther e are only about 10，000 of the creatures in the world可知，世界上蓝鲸的存活量很少，他们正逐渐消失，故答案为C．
27．D，推理判断题，根据这个安排的内容Sailing slower will allow the ship's members more time to look at detection（探测） equipment and-more important-to change course before hitting a whale．使船减速是为了又时间探测鲸的位置，避免撞到它，其目的是为了保护蓝鲸，故答案为D．
28．B，推理判断题，本文讲述了蓝鲸的生存现状，由于生存受到威胁，相关部门制定了许多保护蓝鲸的措施，因此有可能是新闻报道，故答案为B．
