10．______ the job ahead of time，they decided to go to Phuket Island for a holiday．（　�。�
A．Having finishedB．Finishing
C．To have finishedD．To finish

分析 已經(jīng)提前完成了工作，他們決定去Phuket Island度假．

解答 答案A  本題考查非謂語動詞  由題干可以得知，逗號后句子完整且沒有連詞，逗號前應(yīng)該使用非謂語動詞，finish與邏輯主語they之間是主動關(guān)系，finish的動作發(fā)生在謂語動詞decide動作之前，有明顯的先后順序，故用現(xiàn)在分詞的完成式作時間狀語，不能使用不定式，故答案為D．

點評 本題屬于非謂語動詞的考查，應(yīng)該學(xué)會先判斷語態(tài)，根據(jù)非謂語動詞與邏輯主語間的主被動關(guān)系可以排除部分干擾項；再根據(jù)時態(tài)排除部分干擾項，從而可以得出正確選項．

1．As long as you have broadband（寬帶）service in your home，you can turn on your desktop computer and connect to the Internet．If you have a wireless router（路由器），a device that spreads the broadband connection to other devices，you can set up a Wi-Fi network，which enables your cellphone and tablets to go online too．And when you are outdoors where there is no Wi-Fi，such as in the park or at the beach，having 3G service allows you to stay connected．
    It seems that lots of us already have Internet coverage everywhere we go．So why have mobile companies around the world lately been so enthusiastic about a new term，"4G"？First，you need to know that the letter"G"stands for"generation"．Even if you have no idea what 4G is，at least you can figure out that it's a step up from 3G since it's the latest generation of mobile internet service．
Unlike broadband，mobile Internet uses the same signal towers that provide voice service to your cell phone，which means wherever you can make phone calls with your cell phone you also have an Internet connection．
But mobile connections have theirdefects：they don't carry as much information as broadband does，making opening websites and downloading music slower than they are on a Wi-Fi connection．This is why mobile connections have been constantly upgraded since the first generation was launched back in the l980s．
    According to BBC，4G is five to seven times faster than current 3G network speeds，almost as fast as home broadband．Because of this，4G is ideally suited for services like video downloading，mapping，online shopping and even video conferencing．
    To achieve the high speeds，network companies have to spend a lot of money on building new signal towers，which will eventually lead to a higher phone bill if you switch t0 4G，and you'll also have to get a new phone with 4G capacity．

56．What is Paragraph l mainly about？D
A．The development of Wi-Fi．
B．The convenience of using cellphones．
C．The influences of the Internet on our life．
D．Various ways to get access to the Intemet．
57．The underlined word"defects''in Paragraph 4 probably meansA．
A．disadvantages    B．functions    C．qualities   D．benefits
58．What is the weakness of 3 G compared with 4G？C
A．Its voice is not as clear as 4G．
B．It can't satisfy the users'basic needs．
C．Its network speeds are much slower．
D．It has much less popularity than 4G．
59．Mobile technology has constantly been improved toB．
A．replace broadband        B．increase the network speed
C．download videos         D．connect more cellphones
60．What does the author think of 4G service？D
A．Its service is worth the price
B．There is no need to develop it
C．It takes time to be widely used
D．It provides good service at a higher price．

18．Apple's iPod completely changed the way people experience music．What will it do for television？
The industry was intrigued by Wednesday's announcement that episodes of the hit ABC shows"desperate Housewives"and"Lost"will be available for Apple's new video iPod．Episodes will go on sale for $1.99on iTunes the day after they are broadcast．
For ABC and its parent Walt Disney Co．，the bet is that the new technology will bring in more new fans of the programs than will be taken away from watching them on traditional broadcast television．
The network's affiliates（廣播電視網(wǎng)的成員） were not told the deal was in the works before Wednesday，and they're the people most likely to be concerned about its impact．Now the iPod will join digital video recorders and DVDs as another way of seeing television programs other than their regularly scheduled times on the ABC stations．
Leon Long，chairman of ABC's affiliate board said if viewers have the choice of watching"desperate housewives"on their wide-screen television with surround sound or a two-inch iPod screen，they will almost certainly watch it on TV．The iPod option will likely be attractive to people who missed an episode and want to keep up with the story，he said．
He noted that two of the three series ABC is offering to iTunes-the new"Night Stalker"is the other-are serials（系列片） that require viewers to follow story lines that play out over several months．
At the beginning，the downloads might also appeal to techies who want to try out the new product and might not necessarily be fans of the programs，which could bring these shows a new audience．
As for the chance it will pull people away from his station，Long said，"It's certainly a risk but I don't think it's a great risk．"

57．From the passage，we can guess thatA？
A．episode means a part of a TV show broadcast in several parts
B．iTunes here refers to a musical store seen everywhere
C．iPod is a kind of media player only used for music
D．ABC is a small local American television company
58．Why are the network's affiliates most likely to be concerned about the deal's effect？A
A．Because they are worried it may affect their TV programs．
B．Because people ill have another way of watching TV．
C．Because they want the iPod to join their organization．
D．Because they didn't know what was happening．
59．According to Chairman Leon，we learn thatD．
A．only techies will show interest in the downloads
B．it's impossible for iPod to take away TV viewers
C．the TV shows to be offered by ABC are very boring．
D．most people prefer to watch a play on TV rather than on iPod
60．What would be the best title for the passage．C
A．A great risk for television station．
B．iPods will bring new fans to TV shows．
C．Will iPods change TV the way it changed music？
D．Which is better，wide-screen TV or narrow-screen iPod？
