20．I don't know what it is．No matter（51）whenI go to a post office and no matter where the post office is，I always find myself（52）standing（stand） in line behind someone who has a lot of business to do．
One day，I had to buy a couple of st amps，but I had to wait behind an old lady who took fifteen minutes（53）to finish（finish） a form that a child could do in one minute．Feeling（54）thatI could not stand waiting in such a line any longer，I decided to join（55）anotherone．It seemed twice as（56）longas the first line，but at least it was moving．It turned out to be the worst choice I had ever made．As soon as I lost my place in the first line，the one I joined slowed to a stop．I had no choice（57）butto wait behind a schoolboy（58）whowas taking half an hour to choose a new set of postcards．At last it was my turn．I nearly jumped for joy．Then the clerk behind（59）thecounter，a middle-aged fat guy，stood up，pushed forward a printed sign saying"Position Closed"and（60）said（say） without a smile，"Sorry，going to lunch．"

分析 每次我去邮局，总是排在队伍的后边．买邮票时由于前面的老妇人太慢，我换了另条队，好不容易排到我时却到了午餐时间．

解答 1．when 考查连词．No matter when的意思是"无论何时"，故填when．
2．standing 考查非谓语．find是及物动词，其后要跟宾语myself，stand的逻辑主语是我，两者之间是主谓关系，所以用现在分词standing在句中做宾语补足语．
3．to finish考查不定式．在英语中，it takes/took sb．+时间+to do sth．，故填to finish．
4．that 考查宾语从句．后文句子是feel的宾语从句，从句中是个主谓结构的句子，所以用that来引导．．
5．another 考查代词． 在英语中，another泛指另一个．根据句意我决定加入到另一个队伍，所以答案填another．
6．long 考查固定结构．在英语中，as long as是固定搭配，意思是：和…一样长．
7．but 考查固定结构．在英语中，have no choice but to do sth．是固定搭配，意思是"除了…别无选择"．
 8．who 考查定语从句． 本句中的先行词是schoolboy在定语从句中做主语，所以关系代词用who来引导．
9．the 考查冠词．在本句中，由于counter是名词，需要一个限定词修饰，故填the，这里是特指．
10．said 考查时态和语态．分析句子，可知此处要用一个谓语动词．由于前面的动作都是表示过去，故用一般过去时，填said．

点评 语法填空是通过语篇在语境中考查语法知识的运用能力，在解题前应快速浏览短文掌握大意，在读懂短文的基础上，结合短文提供的特定的语言环境去逐句分析．要解决好语法填空，离不开坚实的语法知识，有了坚实的语法知识才能对语言进行正确的分析和判断，从而答对题目．

11．Scientists from the United States say they have found fish and other creatures living under key waters in Antarctica．They made the announcement after completing three months of research at the Ross Ice Shelf-the world's largest floating ice sheet．
The researchers hoped to find clues to explain the force of the melting ice and its effect on sea level rise．Reed Scherer and Ross Powell are with Northern Illinois University in DeKalb，Illinois．They just finished up their research on our southernmost continent．Money for the project came from America's National Science Foundation．
"We chose a study site where，in the first year，we went into the subglacial（冰川下的）lake and tried to understand the environment there，both ecologically and in terms of the ice dynamics about how the lake operates，and how the sediment（沉淀物）underneath the ice sheet operates，as well，because it's the water and the sediment underneath the ice that control how fast the ice is flowing into the ocean．"says Ross Powell，who led the investigation．The team included scientists，engineers，machinery and other supplies across the ice from the main U．S．scientific base at McMurdo Station to the researcher's camp．The camp was near a subglacial lake，where an earlier study took place．
Ross Powell says the latest study may provide evidence that can help predict the effect of climate change on rising sea level．
"What we have found is that these are very sensitive areas to the stability of how dynamic the ice is and how fast the ice may react to increases of melting both from the ocean and the atmosphere．"
Among the new instruments built for the project was a powerful hot water drill．The researchers used the drill to dig down some 740 meters．They collected water，sediment and other material from the grounding zone．
Working around the clock before the deep hole refroze，they sent a video camera down to the 400-square-meter undersea area．
Reed Scherer says the video images they saw in the Command Center were a total surprise．
"It's a very mobile environment．The bottom is changing constantly．And so the things that we saw were all very mobile organisms，things that swim and some things that crawl．And obviously they are getting enough nutrition that they can thrive on．Some of the little crustacean-like creatures called amphipods that we saw swam quite quickly and were quite active．"
This is the farthest south where fish have ever been seen．How did the creatures get here？What do they feed on？And what effect will the retreating ice have on them？
Ross Powell says the ice and sediment cores taken from the grounding zone can offer clues．
"We know that the ice is melting there at the moment and so by opening up the cores once they get back，we hope to be able to understand what the ice was doing in the past，relative to what it is doing now．And because it is melting so fast or seems to be melting fast at the moment，we anticipate that there will be some differences that we'll see in the history of the ice sheet from the sediment cores，once we open them up．"But Ross Powell says the work raises more questions than it answers．
