【題目】Section A
Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage.
Write NO MORE THAN THREE WORDS for each answer.
Since the earliest civilizations, people have controlled rivers to meet society's demands. Today, rivers are controlled for many reasons, primarily to maintain reliable water supplies for daily, agricultural and industrial needs, for power generation, for navigation (航行), and to prevent flooding.
River control is achieved by channelization, a term that covers a range of river engineering works, including widening, deepening, straightening and stabilization of banks, and by the construction of dams.
An important period of channelization took place in Europe during the l9'th century, when many large rivers were straightened and their beds deepened. One of the most dramatically changed was the Tisza River, a branch of the Danube that flows through Hungary. The controlling of the Tisza, designed to reduce flooding and make land for agriculture, included cutting off more than 100 meanders (河曲), shortening the river's length by nearly 400 kilometers.
One of the most common ways in which people control rivers is by damming them. The past 50 years or so has seen an increase in dam construction worldwide, and at the beginning of the 21st century, there were about 800,000 dams globally, some towering more than 200 meters in height.
Despite their successes, many dams also cause significant environmental changes that prove harmful. Some particularly deep reservoirs (水庫) can bring about earthquakes due to the stress on their bottom rocks caused by huge volumes of water. Downstream of a reservoir, the river is certainly influenced in many ways: water volume, speed and quality are all affected, leading to changes in the landscape and among plants and animals.

【題目】閱讀下列材料，從每題所給的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)，并在答題紙上將該選項(xiàng)標(biāo)號涂黑。
In 2004 ,when my daughter Becky was ten , she and my husband ,Joe, were united in their desire for a dog . As for me , I shared none of their canine lust.
But why , they pleaded. “Because I don’t have time to take care of a dog.” But we’ll do it. ” Really? You’re going to walk the dog? Feed the dog? Bathe the dog?” Yes, yes , and yes .”I don’t believe you .” We will . We promise.
They didn’t . From day two (everyone wanted to walk the cute puppy that first day ) , neither thought to walk the dog . While I was slow to accept that I would be the one to keep track of her shots , to schedule her vet appointments , to feed and clean her , Misty knew this on day one . As she looked up at the three new humans in her life (small, medium, and large) , she calculated ,”The medium one is the sucker in the pack .”
Quickly, she and I developed something very similar to a Vulcan mind meld (心靈融合) . She’d look at me with those sad brown eyes of hers , beam her need , and then wait , trusting I would understand — which , strangely , I almost always did . In no time , she became my feet as I read , and splaying across my stomach as I watched television .
Even so , part of me continued to resent walking duty .Joe and Becky had promised. Not fair , I’d balk (不心甘情愿地做) silently as she and I walked . “Not fair , ” I’ d loudly remind anyone within earshot upon our return home .
Then one day — January 1, 2007 , to be exact — my husband ‘ s doctor uttered an unthinkable word : leukemia ( 白血病) .With that , I spent eight to ten hours a day with Joe in the hospital , doing anything and everything I could to ease his discomfort. During those six months of hospitalizations, Becky, 12 at the time, adjusted to other adults being in the house when she returned from school. My work colleagues adjusted to my taking off at a moment's notice for medical emergencies. Every part of my life changed; no part of my old routine remained.
Save one: Misty still needed walking. At the beginning, when friends offered to take her
through her paces, I declined because I knew they had their own households to deal with.
As the months went by，I began to realize that I actually wanted to walk Misty. The walk in the morning before I headed to the hospital was a quiet, peaceful time to gather my thoughts or to just be before the day's medical drama unfolded. The evening walk was a time to shake off the day's upsets and let the worry tracks in my head go to white noise.
When serious illness visits your household, it's , not just your daily routine and your assumptions about the future that are no longer familiar. Pretty much everyone you acts differently.
Not Misty. Take her for a walk, and she had no interest in Joe's blood counts or ’one marrow test results. On the street or in the park, she had only one thing on her mind: squirrels! She Was so joyous that even on the worst days, she could make me smile. On a daily basis she reminded me that life goes on.
After Joe died in 2009，Misty slept on his pillow.
I'm grateful一to a point. The truth is, after years of balking, I've come to enjoy m’ walks with Misty. As I watch her chase after a squirrel, throwing her whole being into the here-and-now of an exercise that has never once ended in victory, she reminds me, too, that no matter how harsh the present or unpredictable the future , there's almost always some measure of joy to be extracted from the moment.
