10．Obama，         president of the USA，is trying to help the Americans suffering from Wall Street crisis make the         needed to re-balance their lives．（　　）
A．a；changeB．the；improvementC．/；decisionD．/；adjustment

分析 奥巴马，美国总统，正在努力地帮助深受华尔街危机影响的美国人做出必要的调整来重新恢复（平衡）他们的生活．

解答 答案：D．
第一个空表示特指美国的总统，所以用定冠词the；第二个空构成一固定短语make the adjustment作出调整；故选D．本句中Obama为句子的主语，the new president of the USA，主语的同位语，谓语部分中包含重要结构是help sb do sth，其中suffering from Wall Street crisis 为现在分词短语作后置定语，修饰the Americans；needed为过去分词作后置定语，修饰the adjustment；to re-balance their lives这是不定式做目的状语．

点评 对于冠词要注意他们的所指是泛指还是特指，并根据句子的意思来做出最后的判断．

1．"So，what are you doing after graduation？"（71）FHowever，you have to make up your mind as your last high school year begins．Whether your plans include college，heading straight for the workforce，or taking a year off，here are some practical tips to prepare yourself for the journey．
Going to College
Some people know from an early age exactly what they want to be and how they plan to get there．（72）EAccording to a recent survey，75% of students change their majors after they enter college．After all，school is also not just about careers and getting a high-paying job after graduation-it's a place for learning about yourself and the world．
Selecting a School
If college is in your future，you need to plan．Start by asking yourself questions about your preferences．（73）GOnce you've narrowed down your choices，ask the schools to send you literature or visit their websites．
Getting a Job
Maybe you've decided that college isn't for you-right now，anyway．If you want to join the workforce，opportunities are out there for people who don't have degrees．Some products-selling or service industry organizations offer training programs to high school graduates．Search the classified ads in the newspaper and do some Internet research．（74）D
Taking Time Off
What if you intend to go to college but just don't feel ready to start yet，for whatever reason？（75）BThis practice is common in some countries，like the United Kingdom，where it's called a"gap year"．Even if you decide not to apply to college，it can be a great idea to take a year to do something you may not have an opportunity to do again．Lots of volunteer organizations would welcome your time and energy and would provide you with a wonderful learning experience．
 
A．You might want to get a high-paid job first．
B．You might want to take a year off to pause．
C．This is the fact that young people have to take into consideration．
D．Most large companies list their job openings on their websites．

19．At most schools，"going green"means generating less trash or making an attempt to recycle．But at New York's Riverdale Country School，it means being encouraged to run and even jump in the hallway．That's because the school was the first to install （ 安装 ） the specially-designed Pavegen floor tiles （地砖） in America．
The tiles use kinetic energy （动能） expanded by the kids and transform it into electricity that can be used to power classroom lights，science projects and charge electronic devices．The first US installation of Pavegen tiles near the school's student center is thanks to 14-year-old Zach Halem，who managed to convince the officials to purchase them．
Besides providing fun green energy，the tiles also serve as a learning tool．Every time a student steps on one，a brightly-lit LED board provides instant feedback （反馈信息） on how much energy was generated．Depending on the force，every step results in between one to seven watts-enough power to light an LED street lamp for about 30seconds．
Made largely from rubber and other recycled materials the tiles are invented by the 26-year-old British industrial designer Laurence Kembell-Cook．While new to the US，they have been installed in numerous places in Europe，ranging from a London underground station to a marathon track in Paris．However，it was not until Pavegen started getting popular in London schools that Laurence realized that his invention not only saved energy，but was also fun!
Though the young inventor will not give too many details about the technology behind this green tile，he says that it is very different from other kinetic energy harvesting systems．
Whatever the secret，let's hope more US schools decide to install these fun tiles．In fact，why stop at schools？These tiles could be installed everywhere，from sidewalks to homes．Then we could all be"green"and have fun!Who knew that was even possible？
13．What can we learn from the first paragraph？C
 A．American students are encouraged to run and jump as much as possible．
B．"Going green"means generating less trash or making an attempt to recycle．
C．New York's Riverdale Country School took a different way to go green．
D．New York's Riverdale Country School is the first US school to try new ways to go green．
14．Which of the following statements is TRUE about Laurence Kembell-Cook？A
A．His original motive to invent the Pavegen tiles was to save energy．
B．He believed his invention would be popular with students．
C．He keeps all the technology behind this green tile a secret．
D．He persuaded the school to install Pavegen tiles．
15．Which part of a website is the passage probably taken from？A
A．Science．B．Architecture．
