1、河南省太康一高届高三英语上学期第二次月考试题无答案新人教版太康一高高三周练题第一部分 阅读理解(共两节,满分40)第一节(共15小题;每小题2分,满分30分)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. ANowadays, there is a heated debate on whether pollutants should be cleaned in the air. Cleaning up the air, while good for our lungs, could make global warming worse. And the polluta

2、nts still go up around the air, along with carbon dioxide.These pollutants are called aerosols (气溶粒) and they include soot as well as mixtures of nitrogen(氮) and sulfur(硫) and other stuff into the air. Natalie Mahowald, a climate researcher at Cornell University, says so far, scientists have mostly

3、tried to understand what those aerosols do while theyre actually in the air.There are so many different kinds of aerosols, she says. Some warm and some cool. But in fact, humans are giving out a lot of extra aerosols, and they tend to cool for the most part.The aerosols reflect sunlight back into sp

4、ace, or keep us cool. But it turns out thats not all they do. These aerosols also influence how much carbon dioxide gets drawn out of the air by plants on land and in the sea.They can add nutrients, for example, to the oceans or to the land, Mahowald says. But also while theyre in the atmosphere the

5、y can change the climate, and thus that also can influence the amount of carbon, the land or the ocean can take up. So there are quite a few different ways that aerosols can act on each other.Mahowalds results suggest that reducing those pollutants could be an even bigger problem than realized, when

6、 you consider that aerosols help remove carbon dioxide from the air by encouraging plant growth. Hard numbers on this effect are highly uncertain at the moment, but this could turn out to be quite significant.And studying it is not easy because the effects arent well understood. For example, nitroge

7、n can be a fertilizer (肥料), but it can stop plant growing when nitrogen comes out of the air in acid form.Right now it seems like were much more likely to clean up aerosol pollution, while increasing the amount of carbon dioxide in the air. So scientists, unfortunately, may have a chance to see whet

8、her this experiment on our planet should continue or not.1. From Paragraph 2, we know thatA. scientists have been aware of how aerosols workB. cleaning up the air is so popularC.

11、enger on the subway who caught a glimpse of me may have already thought that I was strange. In particular this gentleman sitting opposite me was staring at me, at the cheese bun on the floor in front of me, and then back at me; “Next stop, St. Patrick Station” my stop was quickly coming up. I had mi

12、nutes to either take the cheese bun, which nobody else was claiming(as a passenger probably dropped it by mistake and got off at a previous stop), or leave it there and hope that it didnt go to waste.In those few minutes I felt my pride getting in the way. “What would other people on this subway thi

13、nk of me if I took the Cheese bun? Would they think that I was poor and hungry? Would they think that Im stealing?”The ignorant thing to do was say “yes” to any of those self-imposed (强加的) questions, which would only justify my ego. But then Id get off the subway, walk a block up the street to my of

14、fice, get settled at my desk, and despite feeling comfortable, warm, and being well-fed myself for the whole day, there would be a weight of guilt and regret weighing on my consciousness.My thoughts were pushing me towards pride and ignorance when the truth was evident：this missing cheese bun is a g

15、ift. For a homeless person who is hungry and cold. For me to overcome a little bit of ego and pass along so much kindness. It was clear that the homeless person who would receive this cheese bun needed it just as much as I did. gkstkJust as the doors opened at my stop I grabbed the cheese bun and ex

16、ited the subway. It felt awesome and I didnt care if people were looking or what they thought. Instead of going directly to my office as usual, I walked a few more blocks up to Queens Park where I have seen a homeless man sitting outside many times on my walk from the gym to my office. I always want

17、ed to give him something. There he was this morning, wrapped in a sleeping bag.5. As the author was getting off the subway, he _.A. felt worried about where to go because he was a stranger in this cityB. was suffering from hunger as he was hurrying to work without breakfastC. took a glimpse of all t

18、he passengers, especially the gentleman sitting opposite himD. couldnt decide whether to take the cheese bun on the floor in front of him or not6.

From the text we can know the author was _.A. generous B. caring C. selfish D. timid (胆小的)CIf youve ever seen the way people interacted with their pets, it comes as no surprise that theres some germexchanging going on there. A new

21、study indicates that dog ownership specifically may be one of the biggest single contributors to what kinds of microbes that live on your skin.A team of researchers led by Se Jin Song at the University of Colorado, Boulder, took swabs(化验标本) of the tongues, palms, foreheads and feces(排泄物) of members

22、of 60 family households. Some of the families had children or household pets and some did not; dogs were the only pets swabbed.Researchers then analyzed the DNA of the bacteria they found to determine how diverse the bacteria populations were. Not surprisingly, family members who lived together had

23、more bacteria in common than members of separate households. Bacteria on the skin were especially similar within households, probably because we pass microbes through the air, through direct contact, and via the surfaces we touch. The most surprising thing was that the skin bacteria of dog owners fr

24、om different households were almost similar as if theyd cohabited without a dog. Put another way, you and a friend across town who both own dogs share a skin ecosystem as alike as a married couple does.The reason for this appears to be that dogs harbor some kinds of bacteria that are rare on human s

25、kin. One in particular, a family of bacteria called Methylophilaceae, was abundant in the mouths of dogs sampled as well as the skin of their ownersindicating a common occurrence of oralskin transfer between dogs and their owners, according to the results published in the journal Life.9From the stud

26、y, we know that _A. only dog ownership contributes to the sort of microbes that live on our skinB. nobody finds it surprising that there should be some germexchanging between dogs and their ownersC. there would most probably be no microbe on our skin if it were not for dogsD. some kinds of bacteria

28、Why did researchers analyze the DNA of the bacteria they found?ATo decide whether the bacteria were of the same kinds or not.BTo find out the exact number of the bacteria living on human skin.C To search for the way microbes pass from one member of a family to another.DTo prove that family members w

29、ho lived together had the same bacteria as the members of separate households.DSeated in a convertible (敞篷车) with the top down at 60 miles an hour, Mary looked at the flies that sat on top of Marks hair. How could they stay there? She wondered.Mary had not seen Mark in years, until the other day whe

30、n he came into the caf where she worked. His appearance was different from when he was in high school. Now, he was a bit fat and thick glasses covered his eyes. However, that didnt change Marys feelings for him at all. He had just bought a brand new red sports car and asked her if she would like to

31、go for a ride and then have dinner with him. Her heart beat with excitement as he opened the door for her. She noticed something very strange as Mark got into the car and started to drive away. On the hair was a group of flies just sitting there.Mary stared in amazement. It seemed the faster they dr

32、ove, the more determined the flies were to stick to his hair.Mary remained silent. She leaned forward and turned the radio on, to try to divert her attention away from the flies, but she couldnt help thinking about them. She looked up at Mark, who was completely devoted to what was going on and continued to sing to the music while driving merrily along. Finally, Mark pulled the vehicle over to the side of th
