Question

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（集裝箱） 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（探測(cè)） 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(chǎn) travel guide   
B．a(chǎn) newspaper report  
C．a(chǎn)n advertisement
D．a(chǎn) research paper．

Answer 1

分析 本文講述了藍(lán)鯨的生存現(xiàn)狀，由于生存受到威脅，相關(guān)部門制定了許多保護(hù)藍(lán)鯨的措施．

解答 25．A，推理判斷題，根據(jù)上一段提到All too often，a ship will hit a whale，可知"這個(gè)問(wèn)題"指的就是船撞到藍(lán)鯨的事情，故答案為A．
26．C，推理判斷題，根據(jù)句子Ther e are only about 10，000 of the creatures in the world可知，世界上藍(lán)鯨的存活量很少，他們正逐漸消失，故答案為C．
27．D，推理判斷題，根據(jù)這個(gè)安排的內(nèi)容Sailing slower will allow the ship's members more time to look at detection（探測(cè)） equipment and-more important-to change course before hitting a whale．使船減速是為了又時(shí)間探測(cè)鯨的位置，避免撞到它，其目的是為了保護(hù)藍(lán)鯨，故答案為D．
28．B，推理判斷題，本文講述了藍(lán)鯨的生存現(xiàn)狀，由于生存受到威脅，相關(guān)部門制定了許多保護(hù)藍(lán)鯨的措施，因此有可能是新聞報(bào)道，故答案為B．

點(diǎn)評(píng) 解答任務(wù)型閱讀理解題，首先對(duì)原文材料迅速瀏覽，掌握全文的主旨大意．因?yàn)殚喿x理解題一般沒(méi)有標(biāo)題，所以，速讀全文，抓住中心主旨很有必要，在速讀的過(guò)程中，應(yīng)盡可能多地捕獲信息材料．其次，細(xì)讀題材，各個(gè)擊破．掌握全文的大意之后，細(xì)細(xì)閱讀每篇材料后的問(wèn)題，弄清每題要求后，帶著問(wèn)題，再回到原文中去尋找、捕獲有關(guān)信息．最后，要善于抓住每段的主題句，閱讀時(shí)，要有較強(qiáng)的針對(duì)性．對(duì)于捕獲到的信息，要做認(rèn)真分析，仔細(xì)推敲，理解透徹，只有這樣，針對(duì)題目要求，才能做到穩(wěn)、準(zhǔn)．
