Where do you want to travel this year? What are some of your favorite vacation spots? See some places we have picked as the top destinations for 2010．
● Sri Lanka
The island feels like one big tropical zoo: elephants roam freely, water buffaloes （水牛） idle in paddy fields and monkeys swing from trees．And then there's the beautiful coastline．Among the most scenic is Nilaveli Beach in the Tamil north．Vacationers can lie on poolside hammocks （吊床） under palm trees or swim in its crystal-clear waters．Or they can order cocktails at the Nilaveli Beach Hotel．
● Shanghai
Following up on Beijing's successful Olympics, Shanghai is expecting 70 million visitors to its World Expo．From May 1 to Oct．31, more than 200 nations and regions will turn a two-square-mile site by the city's Huangpu River into an architectural playground: Switzerland will be represented by a building shaped like a map of that country, while England is in the celebrated hands of the designer Thomas Heatherwick．However, by contrast, the United States pavilion might be mistaken for a suburban （郊区的） office park．
● Copenhagen
Last year, thousands of environmentalists challenged world leaders in Copenhagen for the climate summit, but the Danish capital has already emerged as one of the world's greenest, and maybe coolest, cities．In Copenhagen, long, flat roads all have bicycle paths where locals cycle around the city．Away from all the modernism and the happy cyclists, cultural thrill-seekers are being attracted to the district of Norrebro, where the city's young crowd the cafes and galleries or dance in local clubs until the early hours．
64．According to the passage, visitors to the place with natural beauty can have ______．      
A．a vacation on the palm beach                                                      
B．a great time in busy local clubs                                                             
C．a feast for the eyes of architectural wonders                                                      
D．a chance to see an environmentally friendly city
65．Which of the following statements is TRUE about the 2010 World Expo?               
A．Millions of people will visit Shanghai in seven months．                     
B．Switzerland has built something that looks like a map of the world．                                
C．The building of England is designed by Thomas Heatherwick．                                                                
D．The US pavilion reminds people of downtown New York．
66．This passage is probably printed on the ______ page of a newspaper．

A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces (熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.

The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.

After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.

The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!

That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.

But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.

Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.

Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(处理) in the sky!

When the star begins to die ______.

A. there is no fuel left in it                                B. its outer layer goes into space first

C. a huge explosion will happen                         D. it doesn’t give off light any longer

Which of the following doesn’t help produce a black hole?

A. The gravity inside the star is very strong.        B. The light can’t go out of the star.

C. The star becomes smaller and smaller             D. The dying star shines very brightly.

The black hole ______.

A. continues becoming smaller and smaller all the time

B. goes into another universe and becomes a white hole

C. can pull in everything we know of in the world

D. will appear at another place at a different time

What’s the best title for this passage?

A. A New Scientific Discovery: Black Holes

B. How Do Black Holes Come Into Being?

C. What Are Black Holes?

D. Travel Through A Black Hole
