14．For breakfast he only drinks juice from fresh fruit ___ on his own farm．（　�。�
A．grownB．being grownC．to be grownD．to grow

分析 作為早餐，他只喝由他自己農(nóng)場(chǎng)種植的新鮮水果制作的果汁．

解答 答案是A．本題考查非謂語(yǔ)動(dòng)詞；題干中缺少的是fresh fruit的定語(yǔ)，grow（種植）和fruit之間是被動(dòng)關(guān)系，并且"grow"的動(dòng)作已經(jīng)完成，故用過(guò)去分詞表示"被動(dòng)和完成"，答案選A；B項(xiàng)現(xiàn)在分詞的被動(dòng)語(yǔ)態(tài)表示"被動(dòng)和進(jìn)行"，C項(xiàng)動(dòng)詞不定式的被動(dòng)語(yǔ)態(tài)表示"被動(dòng)和將來(lái)"；故B和C錯(cuò)誤；D項(xiàng)沒(méi)有被動(dòng)的含義，排除．

點(diǎn)評(píng) 首先判斷選項(xiàng)中的動(dòng)詞在句中是以謂語(yǔ)還是非謂語(yǔ)形式出現(xiàn)，然后根據(jù)選項(xiàng)在句中的功能結(jié)合非謂語(yǔ)的基本用法做出合理的判斷．要關(guān)注常見(jiàn)非謂語(yǔ)動(dòng)詞的搭配．

4．Do you ever wish for a little more time to do everything you need to do？Well，on July 1 you'll be getting it--but only one more second．
  On July 1 at exactly 7：59：59 a．m．Beijing time （or on June 30 at 23：59：59 UTC，Coordinated Universal Time），the world's atomic（原子的） clocks will pause for a single second，or，more precisely，change to the unusual time of 7：59：60，according to theverge．com．The addition of a leap second（閏秒），announced by the Paris Observatory，is to keep our clocks in time with the slowing of Earth's rotation（旋轉(zhuǎn)） and astronomical time as measured by the sun．
   Just one extra second could cause big problems and affect the way computers and websites work，however．When the last leap second was added back in 2012，more than a few websites had some trouble．As reported by Phys．org，popular sites like the community website Reddit crashed when the leap second was added．
  For Reddit，the problem was eventually found to be with a Linux system that got confused when it checked the network time and found an extra second．
  Speaking to Wired about the problem back in 2012，Linux creator Linus Torvalds commented："Almost every time we have a leap second，we find something．It's really annoying，because it's code （代碼）that is almost never used，and thus not tested by users under their normal conditions．"
  Companies have had to think of their own solutions，and Google's"leap smear"may be the best-known example．As company engineer Christopher Pascoe explains in a blog post，companies usually try to fix the problem by turning back the clocks by one second at the end of the day so that they play that second again．
  However，Pascoe believes this creates problems．He asked："What happens？Does e-mail that comes in during that second get stored correctly？"
  Google has a solution：Cut the extra second into milliseconds and then put these tiny amounts of time into the system throughout the day．"This means that when it became time to add an extra second at midnight，"says Pascoe．"Our clocks have already taken into account over the course of the day．"
  For many companies without Google's money，however，the leap second will likely still cause some crashes．Don't worry，though-at least it won't last long!

51．Why do we need to add a leap second？C
A．The world's atomic clocks are set to do so．
B．To keep in time with the world's computers．
C．To keep atomic clocks in time with the slowing of Earth's rotation．
D．To record the changes to astronomical time．
52．What happened to the website Reddit when the leap second was added in 2012？D
A．It crashed because of a virus attack．
B．Its network time added two extra seconds．
C．All of the code in its Linux system went wrong．
D．One of its software systems got confused and the site broke down．
53．What does the underlined word"something"refer to in the 5th paragraph？A
A．The code not working properly．
B．The extra second．
C．The problem．
D．Normal conditions．
54．How do companies usually deal with the problem of the extra second？C
A．By shutting down computers at the end of the day．
B．By stopping receiving emails that come in during that second．
C．By turning the clocks back by one second at the end of the day．
D．By cutting the extra second into milliseconds throughout  the day．
55．What's Christopher Pascoe's attitude toward Google's solution to the problem？C
A．Unfavorable   
B．Doubtful  
C．Approving  
D．Cautious．
