[单项选择]Globally, recovery is going slightly better than expected, according to the IMF, which released its latest World Economic Outlook today. After shrinking by 0.6% last year, the global economy is likely to expand by 4.2% in 2010, 0.3% faster than the IMF projected in January. But economic performances will continue to vary widely around the world. Much of the upward revision to global growth can be attributed to a better outlook for the American economy. The IMF revised its forecast for American economic expansion in 2010 up 0.4%, to 3.1%. There was no change, by contrast, for the euro area, which already faced a poorer growth outlook. The Euro area economy may only grow by 1% in 2010 and 1.5% in 2011. And much of the job of expansion will be handled by Germany and France, while southern European growth continues to lag. Spain’s economy will continue to shrink in 2010.

A. be in the same rate

The Mysteries of Nazca
In the desert of Peru,300 kilometers from Lima,one of the most unusual artworks in the world has
mystified（迷惑）people for decades.__________ (46) But from high above, these marks are huge images
of birds,fish,seashells,all beautifully carved into the earth.
The Nazca lines are so difficult to see from the ground that they weren't discovered until the 1930s,
when pilots spotted them while flying over the area. In all,there are about 70 different human and animal
figures on the plain,along with 900 triangles,circles,and lines.
Researchers have figured out that the lines are at least 1 ,500 years old,but their purpose is still a mystery.
____________(47)However,it would probably be very tricky to land a spaceship in the middle of pictures of
dogs and monkeys.
In the 1940s,an American explorer named Paul Kosok suggested that the drawings are a chronicle
（记录）of the movement of the stars and planets.__________(48) Later, an astronomer tested his theory
with a computer,but he couldn't find any relation between the lines and movements in space.
Another explanation is that the lines may have been made for religious reasons.British researcher Tony
Morrison investigated the customs of people in the Andes Mountain and learned that they sometimes pray by
the side of the road.It's possible that in the past,the lines of Nazca were created for a similar purpose.
__________(49)But the local people have never constructed anything this big.
Recently,two other scientists,David Johnson and Steve Mabee,have speculated that lines could have
been related to water. Nazca is one of the driest places in the world and receives only 2cm of rain every
year. While Johnson was searching for ancient water sources in the area,he noticed that some waterways
built by ancient people were connected with the lines.Johnson believes that the Nazca lines are a giant map
of the underground water in the area.________(50)
__________（50）
A.Other scientists are now searching for evidence to prove this.
B.A Swiss writer named Erich Von Daniken wrote that the Nazca lines were designed as a landing place for UFOs.
C.Scholars differ in interpreting the purpose of the designs.
D.The largest pictures may have been the sites for special ceremonies.
E.Seen from the ground,it looks like lines scratched into the earth.
F.He called Nazca"the largest astronomy book in the world".
