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 lucfugus),but other species, such as the long-eared bat,the small-footed bat,the eastern pipistrelle,and the Indiana bat have also been affected.In some caves,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 they eat.
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 bats 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.

第9题：
问答题Now many university teachers are troubled by students' cheating on exams. No matter how hard they try to persuade students and to prevent it from happening, this phenomenon seems to be on the increase. In the past, only students poor at study would try to cheat, but now those good students are joining this team. What's more, students who are caught seldom regret their behavior; they only complain about their bad luck. This is really hard to understand for teachers and administrators. The website of a university has started an online discussion about .why students cheat on exams, and you are expected to write an article of about 400 words to join this discussion. You can decide the title for your article. In the first part of your writing you should present your thesis statement, and in the second part you should support the thesis statement with appropriate details. In the last part you should bring what you have written to a natural conclusion or a summary. Marks will be awarded for content, organization, grammar and appropriateness. Failure to follow the above instructions may result in a loss of marks.正确答案：
What Has Turned Us Into Cheaters? The writing topic for this year's CET-6 was revealed again before the day of testing. A student has been expelled due to misbehavior in a final examination. This kind of titles has been very popular these days, and all these have revealed a public secret: cheating on exams. This behavior, which was denounced by almost all, is spreading at a high rate, and this has puzzles not only teachers but also the whole society. Then why do students cheat on exams? In my understanding, there are mainly three reasons, (namely unscientific testing, competition for scholarship, and pressure from future job hunting).
Some students cheat on exams to protest against the improper testing format. The purpose of university education should be teaching students to use knowledge to solve problems, therefore, exams and tests should test students' ability to use certain knowledge to solve some problems. But most tests in China just test understanding instead of application, and some exams are even worse because they only test students' memory. Some students think it unnecessary to spend time and effort to prepare for such exams, so they just cheat in order to get a decent score, which in their mind, means nothing. Dr. Wang who specializes in education assessment supported this view in one paper, and he said that teachers should blame themselves because they forced students to cheat.
More students cheat on exams in order to struggle for scholarship. As universities are collecting tuition from students, they also increase the amount of scholarship. This money of cause is very attractive to students, who have virtually no income. As scholarship is mostly decided by examination scores, students willing to get the money will try every means possible. In a recent survey, some good students admitted that they cheat on exams because if most students are cheating, it is unfair when you choose not to. This probably represents a breach of traditional ethics, and is a more important reason than conscientious protest against improper tests.
The most important reason, in my mind, should be the pressure from job hunting. In the past few years the situation in the job market is deteriorating, and this forces students to prepare as early as possible. Due to its importance, students naturally want to make their reports more attractive, and one way to realize it is cheating. As a student said in a news report, students are aware of the cost of being caught, but the profit of not being caught is too much, so many of them just go ahead. Maybe it is not unreasonable to say that it is the society that makes students cheaters.
To sum up, the desires to get a good job and a high scholarship, or simply to signal a protest in current education, have forced us students to copy in exams. It is undeniable that some suffer from weak moral principles, but it is wrong to blame them only. Only when the society and the university find the real source of the problem and deal with it can we restore the traditional criticism against cheating.解析：

第13题：
People have smoked cigarettes for a long time now. The tobacco which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe. In the late 1800s, the Turks made cigarettes popular.
Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco bums, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person′s breathing muscles. Smokers usually take in small amounts that the body can quickly break down.
Nicotine can make new smokers feel dizzy (头晕) or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers′ risk of heart disease and stroke.
Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases.
Tobacco first appeared in ___________.A.Asia
B.Africa
C.Europe
D.America答案：D解析：细节题。根据第一段第二句话“The tobacco which is used to make cigarettes was first grown in what is now part of the United States．”可知答案为D。 -

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 bat,the eastern pipistrelle,and the Indiana bat have also been affected. In some caves,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 hiberna- lion 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 conse- quences. 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 they eat. 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 bats 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.What does the first sentence in Paragraph 1 mean?
A: Bees have been dying mysteriously.
B: The first article on the website is about bees.
C: Bees usually die before bats.
D: It was bees that caused the deaths of bats.答案：A解析：主旨大意题。文章前四段讲述的都是可能造成蝙蝠死亡的原因，但在第五段回归到了蝙蝠死亡导致的严重结果上——严重损害农作物。而在最后一段讲述的是如何帮助减少蝙蝠死亡。归根究底，作者是在讲述蝙蝠死亡的严
根据下文讲蝙蝠神秘的死亡可知，该句是说蜜蜂已经处于神秘死亡的过程中。
根据第一段“...such as the long-eared bat , the small-footed bat , the eastern pipistrelle , and the Indiana bat have also been affected.”可知，这里是列举一些具有各种特色或地区的蝙蝠，因此不难推测pipistrelle是“蝙蝠”的意思。故本题选D。
第三段首句讲蝙蝠死亡的一个可能原因就是缺乏食物，紧接着以纽约蛾的数量近年来一直在下降为例，说明蝙蝠缺少食物。因此蛾是蝙蝠因饥饿而死亡的一个例子。

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 bat,the eastern pipistrelle,and the Indiana bat have also been affected. In some caves,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 hiberna- lion 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 conse- quences. 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 they eat. 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 bats 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.
A: diseases that kill bats
B: insects that bats eat
C: animals that have diseases
D: bat species that are starving to death答案：D解析：主旨大意题。文章前四段讲述的都是可能造成蝙蝠死亡的原因，但在第五段回归到了蝙蝠死亡导致的严重结果上——严重损害农作物。而在最后一段讲述的是如何帮助减少蝙蝠死亡。归根究底，作者是在讲述蝙蝠死亡的严
根据下文讲蝙蝠神秘的死亡可知，该句是说蜜蜂已经处于神秘死亡的过程中。
根据第一段“...such as the long-eared bat , the small-footed bat , the eastern pipistrelle , and the Indiana bat have also been affected.”可知，这里是列举一些具有各种特色或地区的蝙蝠，因此不难推测pipistrelle是“蝙蝠”的意思。故本题选D。
第三段首句讲蝙蝠死亡的一个可能原因就是缺乏食物，紧接着以纽约蛾的数量近年来一直在下降为例，说明蝙蝠缺少食物。因此蛾是蝙蝠因饥饿而死亡的一个例子。
最后一段第一句是主旨句，即你怎样帮助减少蝙蝠死亡。随后列举减少蝙蝠死亡的具体方法。故本题选D。 -

A: All species of bats in North America are dying.
B: Scientists already know the cause of the deaths of bats.
C: The bat deaths are a serious problem.
D: There are many possible causes of the deaths of bats.答案：D解析：文章的题目是“What's Killing the Bats?”第一段引入了蝙蝠离奇的死亡，第二、三段则写了编蝠死亡的几个可能的原因，第五段写了编蝠死亡带来的结果，最后一段告诉人们怎样帮助编蝠。故选D。
由第一段第一句“First it was bees. Now it is bats.”可知最初是蜜蜂；现在是蝙蝠；后边说了编蝠离奇死亡，说明蜜蜂也曾离奇死亡。故选A。
由第一段第四句“Most of the bats affected are…the Indiana bat have also been affect-ed.”知道大多数遭受感染的编蝠是常见的小棕蝠，但是也有其他种类的编蝠，比如长耳编蝠、小脚编蝠、东方的pipistrelle以及印第安纳编蝠。由此可知，pipistrelle指的也是一种编蝠。故选D。
由第三段“Another possible cause is a lack of food. For example, bats typically eat a large number of moths,”可知，moths指的是一种编蝠捕食的昆虫。故选B。
由最后一段首句“How can you help?”及随后的对该问题的回答。故选D。 -

New Foods and the New World
In the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.
According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with.The Arabic legend is used to prove that
A:.coffee was first discovered by Kaldi
B: coffee was first discovered by Kaldi's goats
C:.coffee was first discovered in south American countries
D: coffee drinks were first made by Arabs答案：D解析：细节题。第一段第一句： In the last 500 years , nothing about people—not their clothes,ideas , or languages—has changed as much as what they eat.（在过去的500年中，没有任何关于人类的东西，如他们的衣服，观点或语言，会像他们吃的食物变化那么大）同时使用比较级和否定词表示最高级，意思恰恰就是A选项的内容。
细节题。从第一段最后两句话：London shops where chocolate drinks were served became important meeting places. Some still exist today.（在伦敦，供应巧克力饮料的店铺成为了重要的聚会地点。直到今天还存在一些这样的店铺）可以推断这里的some指的就是London shops。
细节题。第二段第三句：Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the “ Potato Famine ” of 1845～1846.（爱尔兰人非常依赖土豆，在1845年到1846年期间的土豆饥荒中成千上万的爱尔兰人由于土豆欠收而挨俄）。强调the crop failed , the crop即potato。 A项没有说明土豆欠收这个关键事实；B项是starve导致的结果，并非原因;C项文章并未提及。
细节题。根据第三段倒数第二句：But it is native（本土的、当地的）to Ethiopia．句中it即指coffee，意思是咖啡最早产自埃塞俄比亚。A、B项和But it is native to Ethiopia矛盾；根据第三段最后一句：Arabs最早将咖啡制作为饮品。可以推断D是错误的。
推断题。第三段最后一句：It ( coffee ) was first made into a drink by Arabs during the 1400's.最后一段讲述这个阿拉伯传说就是为了证明阿位伯人首先发明了咖啡这种饮品，即D选项的内容。 -
