What's Killing the Bats
First it was bees. Now it is bats. Biologists in America are working hard to discover the cause of the mysterious deaths of tens of thousands of bats in the northeastern part of the country. Most of the bats affected are the common little brown bats (Myotis lucifugus), but other species, such as the long-eared bat, the small-footed hat, the eastern pipistrelle, and the Indiana bat have also been affected. In some cases, more than 90 percent of the bat populations have died.
One possibility is disease. A white fungus (真菌) known as fusarium has been found on the noses of both living and dead bats. However, scientists don't know if the fungus is the primary cause of death, a secondary cause of death, or not a cause at all, but the result of some other conditions.
Another possible cause is a lack of food. For example, bats typically eat a large number of moths (蛾), and in some states such as New York, the number of moths has been declining in recent years. If bats can't eat enough food, they starve to death.
Still other scientists believe that global warming is to blame. Warmer temperatures in recent years have been waking up hibernating (冬眠) bats earlier than usual. If bats break their hibernation at the wrong time, they might not find their expected food sources. The weather might also turn cold again and weaken or kill the bats.
Scientists might not agree on the causes of the bat die-off, but they do agree on the consequences.
Bats are an important predator of mosquitoes; a single brown bat can eat 1,000 or more insects in an hour. They also eat beetles and other insects that damage plant crops. If there aren't enough bats, damage will be great from the insects theyeat. While bats live a long time for their size -- the little brown bat can live for more than 30 years- a female bat has only one baby per year, so bat populations grow slowly. Many bat species in the United States are already protected or endangered.
How can you help? Do not disturb sleeping or nesting bats. If you discover bate that seem to be sick or that are dead, contact your local Fish & Wildlife Department with the details. However, be careful not to touch the animals.

答案與解析
31.D。主旨題。題幹：這篇文章的大意是什麼?根據每段的首尾句，例如“0nepossibility is disease”，“Another possible cause is a lack offood”，“Still other scientists believe that global warming is to blame”，“Scientists might not agree on the causes of the bat die-off”可知，多數段落討論的都是原因(cause)，再結合首段，可以得知談論的是蝙蝠死亡的原因，所以選項D(蝙蝠的滅絕有多種可能的原因)為正確答案。
32.A。猜詞題。題幹：第一段的第一句意思是什麼?根據第一段的首句和上下文，可知首先是蜜蜂，現在是蝙蝠，美國的生物學家正在努力研究蝙蝠莫名死亡的原因，由此可知首句指的是蜜蜂也一直莫名地死亡，故A(蜜蜂一直都在神祕地/莫名地死亡)是正確答案。
33.D。猜詞題。題幹：第一段中的“pipistrelle”指的是__________。利用題幹關鍵詞“pipistrelle”可以定位到第一段的第二句“…but other species，such as the long-eared bat，the small—footed hat，the eastem pipistrelle”，不難看出pipistrelle是蝙蝠的一種。故D(一種蝙蝠)是正確答案。
34.B。細節題。題幹：第三段中的'“moths(蛾)”被作為__________的例子。利用題幹關鍵詞moths可以定位到第三段第二句，可知蝙蝠一般吃大量的蛾子，由此可知B(蝙蝠吃的昆蟲)是正確答案。
35.D。推斷題。題幹：最後一段的目的是什麼?從最後一段的首句“How can you help?”可知談論的是如何幫助蝙蝠，故該題答案為D(為了告訴大眾如何幫助蝙蝠)。
