5.Young people can accomplish what they want through such simple acts as keeping themselves ________ and approaching everything with total commitment.(  )
A.focusingB.focusedC.having focusedD.to focus

分析 年輕人可以通過一些簡單的行動來完成他們想要做的事,像注意力集中,做每件事都專心致志.

解答 答案:B
短語搭配,keep oneself focused全神貫注,專心致志;focus與oneself之間構(gòu)成動賓關(guān)系,要用被動,原本的結(jié)構(gòu)是focus oneself on sth專注于某事.故選B.

點評 過去分詞是非謂語動詞的一種,用法很靈活,分為簡單式done(表示與謂語同時或幾乎同時發(fā)生的動作);完成式having been done(表示先于謂語的動作).學(xué)習(xí)時,要把握其用法特征:表示被動和完成.同時還要注意區(qū)分現(xiàn)在分詞和不定式.

20.JK Rowling,the Harry Potter author,has signed a deal with Little,Brown and Company,to publish her first ever novel for adults,which is set to become one of the most anticipated (期望的) book in years.
The deal means that Rowling's long-standing relationship with Bloomsbury,the London-based publisher that launched (發(fā)行) the Harry Potter books,has come to an end,at 1east in terms of new works by the author.
Rowling is keeping her fans guessing about the characters and plot of her new book.She only said that the new novel will be nothing like the Harry Potter series,which was sold over 30 million copies in the UK alone.She thought that with the move from children's to adult fiction,a switch to a new publisher seemed like a natural and reasonable step.
She said,"Although I've enjoyed writing it every bit as much,this book will be very different from the Harry Potter series.The freedom to explore a new field is a gift that Harry's success has brought me."
Ian Rankin,the Edinburgh-based author whose highly-successful detective novels are also set in the city,suggested Rowling's book will be a crime novel.
"Wouldn't it be funny if JK Rowling's first novel for adults turned out to be a crime story set in Edinburgh?"he said.
Industry insiders guessed that the deal is worth more than£5 million and the new book is expected to come out later this year.
A spokesman said,"JK Rowling's audience is vast and her position is unique.Harry Potter books were a global success and her fans are very loyal.Children that were eight,nine,or ten when the books first came out in the 1990s are now in their 20s.Plenty of adults,loved the books regardless of whether they had children,so the potential market for her is huge."

13.Though she is already one of the most famous pop stars of the 21st century,you've probably never heard of a 25-year-old singer-songwriter called Stefani Germanotta-but that's only because almost everyone knows her by her stage name.Lady Gaga.
Bom in New York City in 1986,Lady Gaga enjoyed music,singing and
dancing from an early age:she started playing the piano when only four years
old and loved performing in musicals at high school.At 17she went to a special
school for the arts but later left because she wanted to become a professional
singer as soon as possible.
She became a global star with her first album The Fame in 2008and followed it in 2009with The Fame Monster.Earlier this year she released a single,"Bom this Way",which broke the record for quickest sales for a piece of music on iTunes,with one million downloads in only five days.Her third album,also called Born this Way,went on sale in May,2011.
Because of how much money she earns,how much she is written and talked about in the media,and how many internet searches are made with her name,F(xiàn)orbes magazine recently put her at number one in its list of the"world's most powerful celebrities".
Most music critics say that what makes Lady Gaga's music outstanding are her strong voice and also the strong electronic rhythm of most of her songs,which makes them popular in nightclubs.They also say her music often sounds a bit like the work of other artists,and she herself is quite open about the fact that goroups such as Queenand female singers such as Madonna have been a big influence on her.
More original than her music,perhaps,is the way she looks A big part of her image is her   outlandish clothes,with her strangest piece of clothing probably having been a dress mande partly out of maet,which she wore once in 2010.
Part of what has made Lady Gaga so famous so quickly is the way she has used social media.She has over 30million Facebook friends,for example,and almost 10milion followers on Twitter.

61.Some people complain about Lady Gaga's music in the following except thatA.
A.she is often dressed strangely and differently from others

C.her music is in some way copied from others
D.she has been influenced by Madonna's singing style
62.What can we learn about"iTunes"?It'sD.

D.a(chǎn) software used to download music from the Internet

17.What is the single largest cause of sick leave in the UK?The answer is not the common cold or flu,but back pain.Back pain affects one in three British adults,costs the country over 5billion pounds every year and is very difficult to treat.But now Britain's National Health Service(NHS)will be offering a new solution:acupuncture.The ancient Chinese needle therapy(療法)has been around in the UK for many years,but this is the first time it has been officially approved by the NHS's advisory body,the National Institute for Clinical Excellence(NICE).
Traditionally,doctors in the UK have advised back pain sufferers to stay active,do stretching exercises and take painkillers when necessary and in more serious cases some people are given X-ray treatment or injections with therapeutic substances.
NICE,however,say there is evidence that acupuncture may be more effective than expensive X-rays or injections,so patients who have been suffering for over six weeks should be given a choice.As an alternative to acupuncture,patients will be able to choose for either a course of spinal manipulation(脊柱推拿術(shù)),or a series of special exercise sessions.In the UK,acupuncture is classed as a complementary therapy,which is the term given to a medical procedure which hasn't received the strict trials by which scientists prove some treatments work.
While many experts have welcomed the move to make acupuncture available on the NHS,some are still doubtful about its effectiveness.Research from the US earlier this month found that using toothpicks could be as good as using real needles.So while some are yet to be convinced,back pain sufferers will be hoping that acupuncture helps get them feeling healthy and mobile again.Employers,on the other hand,will be hoping it gets them back to work.

32.What can we learn from the first paragraph?B
A.The British have come to know acupuncture recently.
B.About thirty percent of the British suffer from back pain.
C.NICE has been arguing against Chinese needle therapy.
D.The British ask for sick leave mostly because of cold or flu.
33.The traditional ways to treat back pain in the UK includeC.
A.staying in bed for rest    
B.Chinese needle therapy
C.receiving X-ray treatment 
D.a(chǎn)voiding physical exercises
34.In treating back pain,acupunctureA.
A.may cost less than X-rays    
B.works surely better than injections
C.has gone through strict scientific tests 
D.will replace the traditional ways in the UK
35.What do experts think of acupuncture?D
A.They think highly of it.    
B.Most of them are against it.
C.Few recognize its usefulness.
D.They differ on its effectiveness.
