阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

　　Most of us think that when we step under a shower we’re getting clean．We are, but we're also giving a home to lots of tiny little creatures we didn't even know about．

　　A showerhead carries thousands of bacteria(细菌)called Mycobacterium．These can cause problems like coughs and tiredness, and a general feeling of poorliness(身体不舒服)．When you turn on the water, the bacteria go from the showerhead onto and into your body．

　　This is a finding of Norman R．Pace and his team at the University of Colorado, in the US．The scientists investigated bacteria in all kinds of human environment, including showers．

　　Pace's team looked at 45 showerheads in nine American cities．They discovered that 30 percent of them had large amounts of flying Mycobacterium．

　　But Pace said that they pose few threats to the health．Only those with a frail(脆弱的)immune(免疫的)system might need to worry．

　　He told the New York Times that the bactertia are not as unpleasant as might be thought．He said that having a shower is no more dangerous than anything else we do in the morning．

　　But for those who feel sick about the idea of all those microorganisms(微生物), he had some advice．

　　Let the water run for 30 seconds before getting into the shower．Why? The number of bacteria is smaller than when the water is just turned on．If that seems like a waste of water, he added that you could also change your showerhead every few months．

　　But Pace had good news too．He has also been testing the air in US subways．Apart from iron particles(粒子), which are ground off the track by the wheels of trains, subway air is fresh．The reason is that a train's movement pumps fresh outdoor air into the tunnels(隧道)．

　　Pace explained that he wanted to understand the natural microbial(微生物的)environments of public places．This kind of knowledge might help detect the microbes to be used in a bioterrorist(生物恐怖分子)attack．

(1)

According to the finding of Norman R．Pace, after taking a shower, we might ________．

[　　]

A．

get much dirtier

be covered by bacteria

get a frail immune system

D．

of 45 showerheads surveyed in nine cities, 30 carried large amounts of Mycobacterium

(3)

According to the research of Pace's team, which of the following contributes to fresh air in US subways?

[　　]

B．

Iron particles．

(4)

The word “detect” in the last paragraph probably means “________”．

[　　]

A．

B．

to protect

C．

to make

D．

to prevent

答案：1．D;2．B;3．C;4．A;
解析：

(1)

(2)

考查细节理解。从第八段可知B项陈述正确。

(3)

考查细节理解。第九段说，他们的研究发现，地铁列车的来回移动将外面的空气抽到隧道里，因此地铁的空气很新鲜。

(4)

考查猜测词义。从语境看，划线词表示了解公共场合的自然微生物环境，了解这方面的知识能帮助我们“监测/发现”恐怖分子的生物攻击所使用的微生物。

Researchers who helped discover a new species of Mexican butterfly are offering to sell the naming rights to raise money to fund more research. Co-discoverer Andrew Warren is hoping to raise at least $50,000 by auctioning(拍卖) off the rights to name the 4-inch “owl eye” butterfly, which lives in Sonora, a Mexican state bordering Arizona.

“That would support at least two years of research for our team down in Mexico,” Warren said. “Money goes a long way down here in Mexico.”

According to the scientific tradition, discoverers of a new species have the say in naming it. In recent years, some discoverers have auctioned off their naming rights to raise money.

Warren said the amount being sought for the butterfly is not out of the question, noting that naming rights for a new monkey species brought in $650,000 two years ago. A group of 10 new fish species that went on the naming auction block at the same time earlier this year brought in a total of $2 million.

The butterfly discovered by Warren and researcher George Austin ranges as far north as Mexico.

The butterfly was actually in a collection, misidentified as an example of another new species, at the McGuire Center for Lepidoptera and Biodiversity at the Florida Museum of National History in Gainesville, said Warren. They soon began the hard process of determining that it was indeed a “new” model of butterfly.

After checking photos and comparing it with other known species, they determined it was a separate species.

Where did the researchers discover the new species of butterflies?

   A. In Sonora.                        B. In Mexico state.       

   C. In a place in US.                D. Near the US-Mexico border.

Why will the researchers sell the naming rights of the butterfly?

To raise money for wildlife protection.

To raise money for more research.

To cause people’s attention to the new discovery.

To cover the cost of the research.

When the butterfly was first discovered, people thought ______.

it was a new species at once

it wasn’t a species of American butterfly

it belonged to the monarch branches

it belonged to a new species

We can infer from the passage that ______.

the new species of butterfly live both in the US and Mexico

it took the researchers a lot of efforts to determine the new species of butterfly

the researchers are not sure whether they can get the money they want from the auction

it is the first time that the new species of butterfly has been found
