3．一Is there an express to Beijing tonight？
-There______be，but you'd better call the booking office Io make sure．（　　）
A．canB．mightC．willD．must

分析 --今晚有到北京的快车吗？
--也许有，但是你最好打电话到售票处确认一下．

解答 答案是B．本题考查情态动词表示推测．can/could表示推测往往出现在否定句或疑问句中；在肯定句中出现时表示"客观上、理论上的可能性"，常常暗示可能性很小，与一般情况不相符．may/might表示推测往往出现在肯定句或否定句中表示不太肯定是推测"也许"；情态动词will表示"愿意；常常；准是"； 情态动词must表示推测只能出现在肯定句中，表示有客观依据的推测"准是，一定是"．本题中由下文中的"你最好打电话到售票处确认一下"，说明说话人不肯定的态度，所以答案是B．

点评 要在正确理解情态动词的基本含义的基础上，整体理解语境中的情感态度，做出合理的判断

A．journalB．scheduleC．altitudeD．forecast
14．Bicycles，roller skates and skateboards are dangerous．I still have scars （伤疤） on my knees from my childhood run-ins with various wheeled devices．Admittedly，I was a foolish kid，but I'm glad I didn't spend my childhood trapped indoors to protect me from any injury．
"That which does not kill us makes us stronger．"But parents can't handle it when teenagers put this theory into practice．And now technology has become the new field for the age-old battle between adults and their freedom-seeking kids．
Locked indoors，unable to get on their bicycles and hang out with their friends，teens have turned to social media and their mobile phones to gossip and socialize with their friends．What they do online often mirrors what they might otherwise do if their mobility weren't so heavily restricted （限制） in the age of helicopter parenting．Social media and smartphones have become so popular in recent years because teens need a place to call their own．They want the freedom to explore their identity and the world around them．Instead of climbing out of windows，they jump online．
As teens have moved online，parents have projected their fears onto the Internet，imagining all the potential dangers that youth might face．
Rather than helping teens develop strategies （策略） to deal with public life and the potential risks of interacting with others，fearful parents have focused on tracking，monitoring and blocking．These approaches don't help teens develop the skills they need to manage complex social situations．"Protecting"kids may feel like the right thing to do，but it denies teens the chances of learning as they come of age in a technology-soaked world．
The key to helping youth in the modern digital life isn't more restrictions．It's freedom-plus communication．Urban theorist Jane Jacobs used to argue that the safest neighborhoods were those where communities collectively took interest in and paid attention to what happened on the streets．Safety didn't come from surveillance （监视） cameras or keeping everyone indoors but from a collective willingness to watch out for one another and be present as people struggled．The same is true online．
What makes the digital street safe is when teens and adults collectively agree to open their eyes and pay attention，communicate and work together to deal with difficult situations．Teens need the freedom to wander the digital street，but they also need to know that caring adults are behind them and supporting them wherever they go．The first step is to turn off the tracking software．Then ask your kids what they're doing when they're online-and why it's so important to them．

18．The need for love is deeply rooted in the human psyche（灵魂）．（71）CSeparateness，according to psychologists，means to be cut off，helpless and alone in the world．It is the source of all anxiety．
（72）A It can be selfish and possessive，or unselfish and giving．Abraham Maslow distinguishes between two kinds of love：B-love or"being love"means love for another person：unselfish love not dependent upon your own needs．D-love or"deficiency-love"is a selfish possessive love which is based upon someone else's ability to satisfy your needs．
D-love is conditional．It depends upon whether personal needs continue to be met．But B-love is unconditional．（73）E Furthermore，as it depends upon who you are，it is possible only when you allow yourself to be known to the other person．
The psychologist Erich Fromm also distinguished between two types of love．（74）F Symbiotic union is an immature love based upon the satisfaction of needs and is similar to Maslow's concept of D-love．
Mature love，on the other hand，is a relationship that allows individuals to retain（保持） their independence，their identity，and their integrity．In mature love people can overcome their sense of separateness yet continue to be themselves．The mature lover would say，"I love you because I need you，"but the mature one："（75）B"

A．There are two types of love．
B．I need you because I love you．
C．Love is a way of overcoming the feeling．
D．Every one of us needs love．
E．It depends not upon what you do，but who you are．
F．They are immature love，called by him symbiotic union（共同体），and mature love．
G．These two types are quite different from each other．

18．Editor Henry Slocum，
     I read your May 10th article in the local newspaper Honesdale Times about electronic books，or e-books，with great interest．You made several good points about the disadvantages of e-books．You may have overlooked，however，some of the ways in which they are superior to traditional books．Yes，e-books are expensive，but they are also convenient．In addition，due to their environment-friendly nature，e-books have the potential to change our planet for the better．
     E-books，for anyone who is unfamiliar with the term，are about the same size and shape as regular books．They have a large screen in the middle，however．This screen shows the reader a page of text that has been downloaded from a computer．Once the reader has finished reading the page on the e-book screen，he or she scrolls down to see a new page．The process continues until the entire book has been read．
     As you pointed out，Mr．Slocum，it's great to lie on a warm，sandy beach with a book．You can do that just as easily with an e-book as you can with a traditional paper book．In fact，because e-books are so light，you can carry them anywhere．Say，for example，that you like to read on the bus．Which would you rather carry with you-a heavy 800-page novel，or an e-book that weighs only a few ounces？
    Another important advantage is offered by e-books as well．They are more environment friendly than traditional books．At present，thousands of trees are cut down each year to meet the publishing industry's demand for paper．Books that don't sell are eventually returned to the publisher and destroyed．This terrible waste could be avoided if everyone used e-books，which require no paper．
Sincerely，
David Eng41．What does Editor Henry Slocum think about e-books？B

B．E-books come in various sizes and shapes

D．E-books are no better than traditional books
44．Which of the following statements is true？B
