[单项选择]

The first 50 years of the next millennium will be critical for the world’s population. By 2050 population growth should have leveled off, but by then we’ll have 10 billion people -- two-thirds as many again as we have today. The rate of population growth is something we can choose right now, though it’s not something that just happens, but a matter of human choice. The choice is a complicated one, with many variables, but it remains a choice.
If we want to prevent a population explosion, we should take action now -- or assist the poorer countries to do so. They need better government, better institutions, better labor and capital markets, better schools.

[简答题]什么是色彩的三属性？

[单项选择]Ten years ago I used to be very fit. I cycled to work during the week days and I got a lot of exercise at the weekends. I used to play tennis a lot and go for long walks. In those days I had a job in an office, but I did not have many things to do, so I didn’t earn very much. I knew it was not a very good job but I had a lot of time to do the things I enjoyed doing.
Then, about eight years ago, I got a much better job. The pay was better. But the hours were a lot longer, too. I bought a car and drove to work every day. I began to take people out to lunch. "Expense account lunches". And I began to put on weight, too. I stopped playing tennis and going for long walks at the weekend because I just didn’t have any time for things like that any more. There’s a lot of stress in a job like mine. Perhaps that’s why I started drinking more than I used to. For example, I used to have only half a glass of whisky when I got home, then I started fining the glass to the top. Then I had another

[不定项选择题]共用题干 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) _________(46)
A.Scholars differ in interpreting the purpose of the designs.
B.The largest picture may have been the sites for special ceremonies.
C.He called Nazca"the largest astronomy book in the world".
D.A Swiss writer named Erich von Daniken wrote that the Nazca lines were designed as a landing place for UFOs.
E.Other scientists are now searching for evidence to prove this.
F.Seen from the ground,it looks like lines scratched into the earth.
