第二部分:阅读理解(10小题,每小题2分,满分40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,并在答题纸上将该选项标号涂黑。

    We have two daughters: Kristen is seven years old and Kelly is four. Last Sunday evening, we invited some people home for dinner. I dressed them nicely for the party, and told them that their job was to join Mommy in answering the door when the bell rang. Mommy would introduce them to the guests, and then they would take the guests' coats upstairs and put them on the bed in the second bedroom.

    The guests arrived. I introduced my two daughters to each of them. The adults were nice and kind and said how lucky we were to have such good kids.

    Each of the guests made a particular fuss over Kelly, the younger one, admiring her dress, her

hair and her smile. They said she was a remarkable (出色的、独特的)girl to be carrying coats upstairs at her age.

    I thought to myself that we adults usually make a big "to do" over the younger one because she's the one who seems more easily hurt. We do it with the best of intentions

    But we seldom think of how it might affect the other child. I was a little worried that Kristen would feel she was being outshined(突出的、优秀的). I was about to serve dinner when I realized that she had been missing for twenty minutes. I ran upstairs and found her in the bedroom, crying.

    I said, "What are you doing, my dear?"

    She turned to me with a sad expression and said, "Mommy, why don't people like me the way

they like my sister? Is it because I 'm not pretty? Is that why they don't say nice things about me as

much?"

    I tried to explain to her, kissing and hugging her to make her feel better.

    Now, whenever I visit a friend's home, I make it a point to speak to the elder child first.

61. The underlined expression ' make a big "to do" over' (paragraph 4) means ______.

   A. show much concern about      B. have a special effect on

   C. list jobs to be done for         D. do good things for

62. The guests praised Kelly for carrying coats upstairs because of her ______.

   A. beautiful hair      B. pretty clothes   C. lovely smile       D. young age

63 Kristen felt sad and cried because ______.

   A. the guest gave her more coats to carry

   B. she didn't look as pretty as Kelly

   C. the guests praised her sister more than her

   D. her mother didn't introduce her to the guests

64. We can conclude from the passage that ______.

   A. parents should pay more attention to the elder children

   B. the younger children are usually more easily hurt

   C. people usually like the younger children more

D adults should treat children equally

   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.

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

       A.get much dirtier                 B.be covered by bacteria

       C.get a frail immune system      D.catch a cough or feel tired

50.Pace’s research into showers shows that ______.

       A.there is no reason to fear microorganism

       B.shower water contains much less bacteria after being left to run for 30 second

       C.having a shower in the morning is more dangerous than at other time

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

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

       A.Train wheels.                B.Iron particles.

       C.The movement of the trains. D.Air conditioners on the trains.

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

       A.to discover      B.to protect        C.to make   D.to prevent
