Dinosaurs ruled the planet for millions of years, and they are generally believed to have gone extinct.But the reality is that modern versions of dinosaurs are all around us. Scientists have been exploring similarities between birds and dinosaurs; and new research shows that these two types of animals are directly linked.

The connections between birds and dinosaurs are explored in a new museum exhibit called Dinosaurs Among Us at the American Museum of Natural History in New York City.

According to Mark Norell, the director of the exhibit and an expert at the museum, it is based on new scientific evidence collected over the last two decades. "I think this is really going to shake up the way people think of dinosaurs “ Norell told reporters.” One could argue that we still live in the age of dinosaurs."

The exhibit includes ancient fossils and lifelike models of dinosaurs of all sizes to show the evolution of dinosaurs into birds. It examines several properties that are shared between the two species, including feathers, complex brains, the shapes. And sizes of eggs, and the ability to fly. Birds today make nests, lay eggs and tend to babies. Fossil research shows that some dinosaurs also made nests and laid eggs. Also，birds have hollow（中空的）bones, which don’t weigh much and allow birds to take more air into their lungs. These adaptations help with flight. Some dinosaurs had these properties as well. In addition, the exhibit shows that there are many similarities between the legs, claws; and feet of dinosaurs and birds.

Norell noted that the research behind this exhibit is the result of advanced scientific, techniques; and new technologies. For example researchers used a scanning (扫描) process called computed tomography (CT) to look inside the brains of extinct dinosaurs. It combines with many X-rays to produce a 3D image. "Modern technology tells us more than we thought

we could ever know about the connections between dinosaurs and birds," Norell said.

Her television career began unexpectedly．When she was 16year old，she had the idea of being a journalist to tell other people's stories in a way that made a difference in their lives and the world．She was on television by the time she was 19years old．And in 1986she started her own television show with a continuous determination to succeed at first．

9．Ernest Hemingway was not only a commanding figure in 20th-century literature，but was also a pack rat．He saved even his old passports and used bullfight tickets，leaving behind one of the longest paper trails of any author．
"Ernest Hemingway：Between Two Wars，"which opens on Friday at the Morgan Library & Museum，is the first major museum exhibition devoted to Hemingway and his work．The largest and most interesting section focuses on the'20s，Hemingway's Paris years，and reveals a writer we might have been in danger of forgetting：Hemingway before he became Hemingway．
The exhibition does not fail to include pictures of the bearded，manly，Hem．He's shown posing with some kudu he has just shot in Africa and on the bridge of his beloved fishing boat，the Pilar，with Carlos Gutiérrez，the fisherman who became the model for"The Old Man and the Sea．"But the first photo the viewer sees is a big blowup of a handsome，clean-shaven，19-year-old standing on crutches．This is from the summer of 1918，when Hemingway was recovering from wounds at the Red Cross hospital in Milan and trying to turn his wartime experiences into fiction．
The evidence at this exhibition suggests that，in the early days，he often wrote in pencil，mostly in cheap notebooks but sometimes on whatever paper came to hand．The first draft of the short story"Soldier's Home"was written on sheets he appeared to have snatched from a telegraph office．The impression you get is of a young writer seized by inspiration and sometimes barreling ahead without an entirely clear sense of where he is going．
F．Scott Fitzgerald （some of whose letters with Hemingway is also on view） famously urged him to cut the first two chapters of"The Sun Also Rises，"complaining about the"elephantine facetiousness"of the beginning，and Hemingway obliged，getting rid of a clunky opening that now seems almost"meta"．In 1929，in a nine-page penciled critique，Fitzgerald also suggested numerous revisions for"A Farewell to Arms．"Hemingway took some of these，but less graciously，and soon afterward his friendship with Fitzgerald came to an end．
The papers at the Morgan show a Hemingway who is not always sure of himself．There are running lists of stories he kept fiddling with，and there are lists and lists of possible titles，including the 45 he considered for"Farewell"and 47 different endings for the novel．
In display case after display case，you see Hemingway during his Paris years inventing and reinventing himself，discovering as he goes along just what kind of writer he wants to be．In a moving 1925 letter to his parents，who refused to read"In Our Time，"his second story collection，he writes："You see I'm trying in all my stories to get the feeling of the actual life across-not just to describe life-or criticize it-but to actually make it alive．So that when you have read something by me you actually experience the thing．You cant do this without putting in the bad and the ugly as well as what is beautiful．"
By the time the Second World War broke out，Hemingway had solidified  into the iconic figure we now remember：Papa．Even J．D．Salinger calls him this．And a blustery，cranky Hemingway appears in 1949 when aboard the Pilar he grabs an old fishing diary and begins scrawling an angry letter to Harold Ross，the editor of The New Yorker，complaining about Alfred Kazin's review of"Across the River and Into the Trees，"not，in truth，a very good book．But，Hemingway，often drinking and depressed，didn't know it，his best work was behind him by then．
66．Which of the following is closest in meaning to the underlined words"a pack rat"（para.1）？D
A．a person who doesn't waste anything             
B．a person who cannot be relied on
C．a person who likes to collect rubbish            
D．a person who enjoys collecting things
67．How many of Hemingway's works are mentioned in this passage？C
A.4             B.5                    C.6                 D.7
68．We can conclude from the Morgan show that sometimes Hemingway was a person．A  
A．unconfident but full of inspirations         
B．stubborn but full of enthusiasm about love
C．casual but full of heroism               
D．bad-tempered but full of strange habits
69．What does the writer truly mean by saying"Hemingway before he became Hemingway"？D
A．Hemingway wrote many masterpieces before he killed himself．
B．Hemingway was once a war correspondent before he became a famous writer．
C．Hemingway devoted all his strengths to writing before he won the Nobel Prize．
D．Hemingway kept exploring the world and adjusting himself before he became a
commanding figure in literature．
70．According to the Morgan show，readers are likely to seeAin Hemingway's works．
①tough men who can't be defeated          
②anti-war fighters
③the dark side of the world as well as its beauty
④love affairs between a man and a woman    
⑤the story of a family business
A．①③B．②④C．①⑤D．③⑤
