单选题{{B}}(C){{/B}} One answer to the question of land shortage was suggested by an organization some years ago. A city was to be built at sea, housing 30,000 people. The suggestion was to shape the city like a harbor (港口). The outer wall of the harbor would stand on steel columns resting on the seabed. Naturally this could only be where the water was fairly shallow. The people would like to live in flats in the fifty-metre high outer wall. The flats would be all face inwards, and would be made of concrete (混凝土) and glass. The glass would be specially made and colored to control the heat and strong light from the sun. The planners called this man-made harbor would be calm. On it would be floating islands carrying more buildings: a hospital, two theaters, a museum, an art exhibition hall and a church. On one of the islands would be a special factory to take the salt out of sea water and turn it into fresh water. People living in the city could move around on small boats driven by electricity, so there would be no air pollution from the burning of gas. There would be platforms outside the man wall for ships bringing supplies. People could also travel to the mainland by motorboat or water plane.

单选题Whatever our differences as human beings are, we all think we're more like the rest of the animal world than we realize. It is said that we share 40 percent of our genetic (遗传的) structure with the simple worm. But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genome (染色体组). To help them do this, they turned to the worm. The nematode (线虫类的) worm is one of the earliest creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life digging holes through sand. But it still has lots to say about human life, and what can be done to make it better. What the worm told Sir John and his colleagues was that each of cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded in our genetic make-up. Many of the diseases that humans suffer from happen when these instructions go wrong or are not obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases hke AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death.
