Information from the pioneer spacecraft of the National Aeronautics and Space Administration (NASA) obviously proves the theory that the burning 900-degree Fahrenheit surface temperature of Venus (金星) is due to an atmospheric greenhouse effect caused mainly by a blanket of carbon dioxide. Such a greenhouse effect is created when energy in the form of sunlight easily passes through a planet’s atmosphere, warms is surface, and becomes heat radiation that is then held in by the atmosphere. The orbiting spacecraft has collected Venus’s atmosphere from top to bottom so that NASA’s scientists are able to prove the exact amount of sunlight received at various places in the planet’s atmosphere and on its surface. Measurements of atmosphere, temperature, and radiative heating foresee Venus’s surface temperature very exactly. The planet is closer to the Sun than it is to the Earth, and it has a thin atmosphere like the Earth’s but Venus atmosphere is made up of more than ninety percent carbon dioxide, compared to less than four percent in that of the Earth. Because of its higher percentage of carbon dioxide, Venus’s atmosphere receives much more heat radiation than the Earth’s does. Thus the Venus studies are believed to be important to the understanding of possible bad effects on Earth’s agriculture and sea levels that could result from the long-term use of fuels, which add carbon dioxide to the atmosphere．

　　Information from the pioneer spacecraft of the National Aeronautics and Space Administration (NASA)obviously proves the theory that the burning 900degree Fahrenheit surface temperature of Venus is due to an atmospheric green- house effect caused mainly by a blanket of carbon dioxide. Such a greenhouse effect is created when energy in the form of sunlight easily passes through a planet's atmosphere (大气), warms is surface, and becomes heat radiation that is then held in by the atmosphere. The orbiting spacecraft has collected Venus's atmosphere from top to bottom so that NASA's scientists are able to prove the exact amount (n.总数,总额)of sunlight received at various places in the planet's atmosphere and on its surface.

通读下面短文，掌握其大意，然后在各题所给的A，B，C，D四个选项中，选出一个最佳答案。
I was in the queue for the supermarket checkout(付款台) earlier today．All of the checkouts were    36  , and the woman behind me was not happy! Every word that came from her mouth was a(n)    37  ! She wasn’t happy with the number of checkouts      38   ; she wasn’t happy with the amount of shopping some people had in their baskets; she wasn’t happy because this supermarket didn’t have a stand where she    39   scan her own shopping.
I listened to her    40  looking around as I loaded my stuff onto the conveyor belt (传送带)．I didn’t want    41   to do with that kind of attitude, and if ever I’d felt like letting someone go     42    of me, it wouldn’t be such a woman!
But then I    43  back．Standing beside the woman was a five-year-old girl,    44   her granddaughter．The girl’s part of the shopping    45  of some comic books.
I couldn’t    46  it．I pushed my shopping back to the end of the conveyor belt,     47   a space．“After you,” I said to the woman and the girl, and    48   them to a big    49   ．The woman was delighted, and even    50   to complain ---- until she was walking away．
So,  51  bother having helped? It was because that little girl was probably taking in her granny’s complaint like a sponge(海绵)．She was learning how to    52   situations like that by listening to her granny．I’d seen that I could interrupt that complaining, and put a smile and some   53   into the middle of it．
We can all complain; we can all react    54   , but it doesn’t have to be like that．And, even if only for a few     55    , I wanted to leave that little soul with just a glimpse of another way．
