A．

which

B．

when

C．

about which

D．

at which

分析每秒11.2千米是被稱之為"逃逸速度"，衛星就是以這種速度脫離地球的引力．

解答答案：D．本句含有非限制性定語從句，先行詞是表示速度的，從句中不缺少主語、賓語或者表語，所以用介詞+關系代詞的結構，在英語中表達"以…的速度"一般用介詞at，所以本題選擇D．

點評認真分析句子結構，弄清定語從句所修飾的先行詞，先行詞所表達的范疇，然后分析從句中的成分，最終確定用什么關系詞．

8．Do you know that people without friends are more likely to die an early death？It's true．However，not all the friends are helpful to up your chances of living a long，happy life．The following types of friends are just what you need to keep the doctor away．
1．A Loyal Best Friend
Sometimes a loyal best friend is the only thing you need to stay calm．Everyone needs a non-judgmental friend who will support them no matter what．This is the kind of friend who knows all of your deepest and darkest secrets，but still loves you all the same．
2．An Honest Confidant
There are certain situations in life where we need to hear the harsh truth．It is really hard for you to face it，but that's what the honest confidant is for．Friends are supposed to be honest with each other．If you find someone who is bravely honest with you （in a constructive way），then hold on to this person!People like that are hard to come by these days．
3．A Polar Opposite
If you only develop friendships with others who follow the same beliefs，customs，and values as you do，chances are you're kept away from the rest of the world．Try to break out of your comfortable zone and befriend people who hold opposing views．You'll learn to accept people who don't see the world exactly the way you see it．
4．A Work Pal
Do you know that with a full-time job，you spend at least 50%of your waking hours at work？Depressing，isn't it？The more isolated you are at work，the more depressed you get．That's why it makes sense to get a work pal to chat with to help you get through the week．You spend 50%of your waking hours at work，and so does your work pal．You'll find it much easier to complain about work with someone than to eat lunch alone every day．
With them in your life，you're bound to live a long and happy life!

17．When University of California-Berkeley released a study this month showing alarmingly high teacher turnover （人員流動） rates at Los Angeles charter （特許） schools，I wasn‘t surprised．
That's not shocking news at local charter schools．It‘s just that the study reminded me of something I'd observed many times，starting with my niece．
Bright and cheerful，my niece longed to teach high-needs children．She started out in the San Francisco public schools，where she was assigned to the district‘s toughest elementary school．Fifth-graders threw chairs across the room-and at her．Parents refused to show up for conferences．
She wasn't willing to deal with this level of indifference and teacher abuse，so she switched to a highly regarded charter elementary school in the Bay Area where she poured her energy into her job and it showed．Her students‘test scores were as high as those in a nearby wealthy school district，despite the obstacles these children faced．
By her fourth year，however，my niece was worn out，running out of the energy it took to work with a classroom of sweet but deeply needy children who begged to stay in her classroom when it was time to leave．The principal‘s offer of a $10，000raise couldn‘t stop her from giving notice．She went to work at that wealthy school district next door-for less money．
Over the years，I've met many teachers who have a passion for their work at charter schools，only to call them the next year and find they‘ve left．The authors of the Berkeley study hold the belief that the teachers leave because of the extraordinary demands：long hours，intense involvement in students complicated lives，continual searches for new ways to raise scores．Even the strongest supporters of the reform movement acknowledge that raising achievement among disadvantaged students is the most challenging task．
It‘s unlikely that we can build large-scale school reform on a platform of continual new demands on teachers-more time，more energy，more devotion，more responsibility-even if schools find ways to pay them better．
This is the bigger challenge facing schools．We need a more useful answer to the Berkeley study than-Yeah，its really hard work．

50．Why wasn‘t the author surprised at the problem？C
A．She had been informed of the problem by her niece．
B．She had participated in the Berkeley study．
C．She had noticed the phenomenon repeatedly．
D．She had been warned of the problem by the media．
51．What can we learn about the students in the public school the author‘s niece taught？B
A．They were clever and cheerful．
B．They were not disciplined．
C．They were indifferent to each other．
D．They were forced to learn by their parents．
52．The author‘s niece left the charter elementary school in the Bay Area becauseC．
A．her hard work and devotion didn‘t pay off
B．her work was not well received by the children
C．the demanding work made her exhausted
D．the mean principle offered her a low salary
53．Which of the following is probably the most difficult for teachers？A
A．Raising disadvantaged students‘scores．
B．Frequent involvement in students‘lives．
C．Indifference from students‘parents．
D．Long working time and much energy．
54．What is the author's comment on the current school reform movement？B
A．It will have a positive impact on education．
B．It tends to be unsuccessful．
C．It will make teachers more motivated．
D．It demands more fund to meet the challenge．
