4.Most of her spare time ______,she still kept on her research in the library.(  )
A.occupiedB.having been occupied
C.to be occupiedD.is occupied

分析 绝大部分空余时间都被占用了,她还是继续在图书馆做调查研究.

解答 答案:A
题干句中有逗号分隔,没有连词,说明不是复合句,要用非谓语动词;spare time与occupy之间是被动关系,要用过去分词;过去分词的完成式表达先于谓语的动作,句意表达的是她占用空余时间做研究,是同步的动作.故选A.

点评 过去分词是非谓语动词的一种,用法很灵活,分为简单式done(表示与谓语同时或几乎同时发生的动作);完成式having been done(表示先于谓语的动作).学习时,要把握其用法特征:表示被动和完成.同时还要注意区分现在分词和不定式.

16.Near the town of Montignac in Southern France,visitors can find some of the most beautiful cave paintings in the world-the Lascaux Cave Paintings(拉斯科洞窟壁画).
    The history of these paintings is very interesting.Most caves are formed(61)bynature under the ground,but some have entrances people can find.That's just what happened one day in 1940.Four boys were taking(62)awalk in the woods near Montignac.As they walked along,one of them noticed an unusual rock.(63)Whenthey got closer,they found it wasn't a rock but an opening in the ground.This opening led to a cave,so they decided to have a look around it.The walls of the cave were(64)covered(cover)with ancient art.The boys didn't know it,but the cave was the find of the century!
    Over the years,many historians and artists came to study the art.They wanted to understand who painted the pictures and(65)whatthey might mean.They soon realized some of the art indicated animals that were on Earth a long time ago.Many of the pictures also showed people(66)following(follow)animals and trying to kill them for food.In the end,historians agreed that this was likely to be the art of a civilization that existed over 15,000 years ago.
    By 1950,over a thousand people from all over the world were visiting the cave every day.But by 1955,the paintings were beginning to become difficult(67)to see(see).Many people were passing through the cave,so the paintings were losing their color.(68)Sadly(sad),people can no longer visit the cave.However,another set of cave paintings has been created.These paintings look exactly the same(69)asthe Lascaux Cave Paintings.People (70)made(make)the paintings so that everyone can still learn about this great ancient civilization.
8.I'm not so sure I like my friends any more.I used to like them-to be honest.We'd have lunch,talk on the phone or exchange emails,and they all seemed normal enough.But then came FaceBook,and I was introduced to a sad fact:many of my friends have dark sides that they had kept from me.
Today my friends show off the more unpleasant aspects of their personalities via FaceBook.No longer hidden,they're thrown in my face like TV commercials-unavoidable and endless advertisements for the worst of their personalities.
Take Fred.If you were to have lunch with him,you'd find him warm,and self-effacing(谦逊的).Read his FaceBook and you'll realize he's an unbearable,food-obsessed boring man.He'd pause to have a cup of coffee on his way to save a drowning man-and then write about it.
Take Andy.You won't find a smarter CEO anywhere,but now he's a CEO without a company to run.So he plays Mafia Wars on FaceBook.He's doing well-level 731.Thanks to FaceBook,I know he's playing about 18hours a day.Andy,you've run four companies-and this is how you spend your downtime?What happened to golf?What happened to getting another job?
Take Liz.She is positive that the flu vaccine will kill us all and that we should avoid it.And then comes Chris who likes to post at least 20times a day on every website he can find,so I get to read his thoughts twice,once on FaceBook and once on Twitter.
In real life,I don't see these sides of people.Face to face,my friends show me their best.They're nice,smart people.But face to FaceBook,my friends are like a blind date which goes horribly wrong.
I'm left with a dilemma.Who is my real friend?Is it the Liz I have lunch with or the anti-vaccine madman on FaceBook?Is it the Fred I can grab a sandwich with or the Fred who weeps if he's at a party and the wine isn't up to his standards?
