【題目】 Bats often appear in movies and literature as frightening creatures. The animals have even been linked in some cultures to vampires, seeking to attack humans and drink the blood of them. In reality, bats are usually not harmful to people. They can do good things for people and the environment. For example, bats eat a lot of different insects that can harm our environment. They can also spread seeds.
But a serious disease is currently threatening the bat population in many parts of the United States. The disease is called white-nose syndrome. It has killed more than 6 million bats across the United States since 2007. Bats catch the disease through their skin while resting on the walls of mountain caves. Biologist Lindsay Rohrbaugh says that the disease spreads quickly and can lead to strange behavior in bats.
In Washington D. C, researchers are studying how white-nose syndrome is affecting the area's nine species of bats. Some scientists are trapping bats on an island in the middle of the Anacostia River to test for the disease. The group is receiving money to help carry out their studies.
Marco Carvello is with the Washington D. C Government's Department of Energy and Environment. "Scientists are concerned that the disease is continuing to greatly reduce the bat population. The bat deaths are affecting the quality of human life in many ways. Without bats, there is an increase of many insects. And that's only going to get worse over time if some ways can't be found," he said.
One theory is that some bats are no longer returning to caves to avoid getting, sick. This means more of them are now making their way into cities, where contact with humans is more likely Experts advise people to keep away from bats in case they have the disease. And animal control officers should safely remove the animals.
【1】According to Paragraph I people tend to think bats __________.
A.should be protected
B.can help spread seeds
C.do harm to human beings
D.may damage the environment
【2】Which of the following might Marco Carvello agree with?
A.The disease has led to people's strange behavior.
B.The-disease may cause the disappearance of bats.
C.The government should control the spread of the disease.
D.The decrease in the bat population can greatly affect humans' life.
【3】What does the author mainly tell us in the passage?
A.A bat species is decreasing in number.
B.We have found ways to protect bats.
C.A disease-causes many deaths of bats.
D.We should have a high opinion of bats.
【答案】
【1】C
【2】D
【3】C
【解析】
這是一篇說(shuō)明文。美國(guó)部分地區(qū)的蝙蝠正在遭受白鼻綜合征的危害而數(shù)量減少,這也將嚴(yán)重影響到人類(lèi)。作者呼吁應(yīng)采取措施控制該疾病的傳染速度。
【1】細(xì)節(jié)理解題。根據(jù)第一段的The animals have even been linked in some cultures to vampires, seeking to attack humans and drink the blood of them. In reality, bats are usually not harmful to people.可知人們總是把蝙蝠和吸血鬼文化聯(lián)系在一起,吸血鬼襲擊人和吸食人血,而事實(shí)上,蝙蝠通常對(duì)人類(lèi)沒(méi)有壞處。即人們總是認(rèn)為蝙蝠像吸血鬼一樣對(duì)人類(lèi)有害。C. do harm to human beings (對(duì)人類(lèi)有害)符合以上說(shuō)法,故選C項(xiàng)。
【2】細(xì)節(jié)理解題。根據(jù)第四段的The bat deaths are affecting the quality of human life in many ways. Without bats, there is an increase of many insects. And that's only going to get worse over time if some ways can't be found," he said. (他說(shuō):“蝙蝠的死會(huì)在很多方面影響人類(lèi)的生活質(zhì)量。沒(méi)有蝙蝠,昆蟲(chóng)的數(shù)量就會(huì)上漲。如果找不到解決的辦法,這種情況將會(huì)更嚴(yán)重!)可知Marco Carvello 認(rèn)為蝙蝠數(shù)量的下降會(huì)影響人類(lèi)的生活質(zhì)量。D. The decrease in the bat population can greatly affect humans' life. (蝙蝠數(shù)量的減少會(huì)在很大程度上影響人類(lèi)的生活)符合以上說(shuō)法,故選D項(xiàng)。
【3】主旨大意題。根據(jù)文章的主要內(nèi)容,尤其是第二段的But a serious disease is currently threatening the bat population in many parts of the United States. The disease is called white-nose syndrome. It has killed more than 6 million bats across the United States since 2007. (但是一種嚴(yán)重的疾病正在威脅著美國(guó)多地的蝙蝠數(shù)量,這種病叫做白鼻綜合征。自2007年開(kāi)始,這種病已經(jīng)造成超過(guò)600萬(wàn)蝙蝠的死亡)可知本文主要講述一種叫白鼻綜合征的病導(dǎo)致美國(guó)多地的蝙蝠死亡。C. A disease-causes many deaths of bats. (一種疾病造成了大量蝙蝠的死亡)符合以上說(shuō)法,故選C項(xiàng)。

【題目】 Bombardier beetles are known for their skillful response to predators (捕食性動(dòng)物).If they are about to be eaten, the insects spray their predators with boiling-hot chemicals. If they get swallowed anyway, they have plan B: Blast (爆炸) their way out from the inside.
In an experiment, scientists watched as a Japanese stream toad readily swallowed an Asian bombardier beetle. But 44 minutes later, the toad vomited (嘔吐) the contents of its stomach. The insect ran away, physically unharmed.
“The vomited beetle was alive and active,” study authors Shinji Sugiura and Takuya Sato of Kobe University in Japan reported in the journal Biology Letters. Why, the researchers wondered, does luck always favor the escape artists? To find out, they needed more of them, and they needed to feed them to more toads. Scientists gathered 15 species of ground beetles, including the bombardier beetle. They also collected Japanese common toads, which are natural bombardier beetle predators, and Japanese stream toads, which do not live in the same place as the insect.
Sugiura and Sato hypothesized (假設(shè)) that over years of exposure, the common toad species developed a greater tolerance to the bombardier beetle's poisonous chemicals than the stream toads had. The bombardier beetles were divided into two groups. Some were poked (戳) with special tools, which caused them to release all their poisonous chemical spray. Other beetles were left alone. Then they were fed to the toads.
The toads that swallowed a fully loaded bombardier beetle were in for a surprise. “An explosion was heard inside each toad, which indicates that the bombardier beetle sent up a chemical spray after being swallowed, the authors wrote. The common toads vomited their prey 35 percent of the time. The stream toads vomited their prey 57 percent of the time. That confirmed their hypothesis about the toads' evolutionary adaptation. All 16 of the vomited insects were “alive and active” 20 minutes later. Almost all the beetles that released their defensive chemicals before meeting the toads were “successfully digested”. The test told the researchers that the beetles' boiling chemical spray was indeed their ticket to freedom.
【1】When Bombardier beetles are in danger, they can ______.
A.have relevant ways to escapeB.bring up the content of stomach
C.cause damage to their enemiesD.make no response to outside attack
【2】What was the scientists’ assumption before the experiment?
A.Bombardier beetles were always lucky to escape.
B.Japanese common toads were natural predators.
C.Common toads had the ability to resist the poison.
D.Bombardier beetles could release poison constantly.
【3】What do we know about Sugiura and Sato’s test?
A.It showed the process of the insects’ evolution.
B.It demonstrated the harm of explosion in the toads.
C.It stressed the importance of a balanced ecosystem.
D.It provided convincing evidence for their assumption.

【題目】 “Fighting like cats and dogs” is a common phrase that people use to mean people argue, fright or don’t get along. If you like cartoons, you’ve probably seen many that describe cats and dogs fighting like sworn enemies (不共戴天的仇敵). There have even been movies made that describe cats against dogs.
As with many questions in life, there’s simply no easy answer to the question of whether dogs and cats can get along. Dogs and cats are different in many ways that can make it difficult for them to get along. However, with patience and the right circumstances, cats and dogs can be best buds (兄弟).
For example, dogs tend to be social animals that are naturally playful. Cats, on the other hand, tend to be more independent. A dog that wants to play might seem aggressive and frightening to a cat. This may lead the cat to defend itself against an attack although that’s really just a desire to play. Similarly, dogs—especially puppies—like to chase each other. It’s a fun game. Chasing cats can be just as fun as chasing other dogs. Again, cats may interpret such playful behavior as a threat.
Even there’s something dogs and cats have in common, tails, but tails can make things confusing. When dog wags (搖擺) its tail, it’s sending a friendly message: “I’m happy. Let’s play.” Cats, however, wag their tails when they are angry. You can see how this might lead cats and dogs to become confused if they’re facing each other with wagging tails!
Although dogs and cats aren’t really sworn enemies dogs are hunters by nature. This means that they might hunt and chase anything that moves-including a cat. This natural behavior that could cause problems between dogs and cats can be controlled by special training called socialization when the animals meet for the first time.
【1】By saying “fighting like cats and dogs”, parents most probably mean that ________.
A.they like neither cats nor dogs
B.their kids don’t get on well with each other
C.cats and dogs fight like sworn enemies
D.the fights between cats and dogs are often made into movies
【2】What may happen when dogs are chasing cats?
A.Dogs become tired out.B.Cats are very happy.
C.Dogs feel enjoyable.D.Cats get injured easily.
【3】Which of the following may be one of the reasons that dogs and cats fight often?
A.They couldn’t understand each other.B.They are worried about their behaviors.
C.They enjoy exactly the same hobbies.D.They wag their tails too often.
【4】What can be inferred from the passage?
A.Dogs are good at hunting animals.
B.Dogs don’t like cats naturally.
C.Cats usually like playing with dogs.
D.Dogs and cats can possibly live in harmony.

Since last September, the Australian bushfires 【1】 (destroy) around 80,000 square kilometers of forest.
