A．had been finishedB．were finished
C．having been finishedD．been finished

分析 所有任務(wù)都提前完成，他們決定去度一個(gè)禮拜的假．

解答 答案：C 題干中有逗號(hào)分隔，沒有連詞，要用非謂語動(dòng)詞；句中finish與task之間構(gòu)成動(dòng)賓關(guān)系，要用被動(dòng)；句意表達(dá)的是已經(jīng)完成的動(dòng)作，要用分詞的完成式；分詞帶有之間的邏輯賓語，是獨(dú)立主格結(jié)構(gòu)．故選C．

點(diǎn)評(píng) 獨(dú)立主格結(jié)構(gòu)由兩部分組成，前一部分是名詞或者代詞，后一部分是非謂語動(dòng)詞（不定式、現(xiàn)在分詞、過去分詞）或形容詞、副詞、名詞或介詞短語．獨(dú)立主格結(jié)構(gòu)本身不是句子，在句子中作狀語，表時(shí)間、原因、條件、伴隨、目的及狀態(tài)等．

14．On March 9th，Apple，probably the most successful technology company in history，held an event to launch its smartwatch，which will go on sale next month．In addition to keeping track of time，the watch measures the wearer's heart rate and activity levels，processes voice commands，gives alerts of incoming e-mails and calls and facilitates payments in checkout lines．In other words，it does a lot of what smartphones already accomplish，but is worn on the wrist and must be close to an iPhone in order to function．Why is there so much buzz about this watch？
  As smartphones have enjoyed a sudden and tremendous boost in global appeal，people have started to wonder what the next major technology trend would be．Many analysts have pinned their hopes on wearable devices，which contain small sensors to track and display information．This category includes everything from smartwatches like Apple's，to fitness bands that measure sleep patterns and exercise，to"smart"shoes that measure distance，to smart glasses that can take voice commands and display information．Wearables promise to measure personal data and save people time：a glance at one's wrist to see alerts takes fewer seconds than pulling out a phone．Companies in various industries，from mining to airlines，are also cautiously testing whether wearables can help improve efficiency or customer service．
  However，while the number of wearable gadgets has grown，consumers still tend to be geeks （對(duì)電腦癡迷的人） and fitness fans．Last year around 21million wearable devices were sold，most of them wrist-worn devices，according to IDC，a research firm．Wearable devices have failed to become mainstream for three main reasons．First，many of them are unable to function without a nearby smartphone，which limits their appeal．Consumers already have to keep track of several devices without adding another．Second，they are not yet considered cool．Google Glass，a pair of"smart"glasses made by the search-engine firm，were so clunky that even fashion models could not make them look good．Third，there is not yet a"killer app"that proves their usefulness in people's daily lives．Technologists imagine a future when wearable devices will serve to confirm personal identity，facilitate payments，unlock house and car doors and track people's activity and wellness．That future，however，is years away．
    Apple has a record of pushing existing technologies into the mainstream，including the Macintosh computer，iPod，iPhone and iPad．This helps explain why people are so interested in Apple's watch．If the firm's new product is attractive enough，it could validate （使…有效）a whole category of technology．Apple has enough loyal fans to sell millions of watches this year．But wearable devices'usefulness for the masses remains uncertain．In the meantime，firms and software developers will need to invest more time and resources in designing new applications that will put the"wear"in wearables．

74．The underlined word"buzz"in the first paragraph probably means"A"．
A．excitement
B．doubt
C．complaint
D．satisfaction
75．Apple's smartwatch has all the following functions except thatC．
A．it makes payments more convenient
B．it informs people of the arrival of emails
C．it enables the wearer to talk to the caller
D．it reacts to commands when talked to
76．What can be inferred from the last two paragraphs？C
A．Apple can become the mainstream in technology because most of its products own attractive appearances．
B．Wearable technology is popular among the majority because it serves various purposes in diverse areas．
C．Firms and software developers need to make wearable devices more wearable to meet the needs of the majority．
D．Many people still want to buy Google Glass even if it doesn't look good on fashion models．
77．What is the purpose of writing this passage？B
A．To tell people about the functions and limits of Apple's smartwatch．
B．To argue that the smartwatch can serve as a good example to improve wearable devices．
C．To encourage various companies to improve their businesses by using wearables．
D．To help consumers differentiate the smartwatch from other wearable gadgets．
