If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the the middle of the 21st century,if present trends continue, we will have used up all the oil that drives our cars,for if scientists develop new ways of feeding the human race,the crowded conditions on earth will make it necessary for lus to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Professor Carl Sagan.
Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.
Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon.
When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.
long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.

BUKHANNON, West Virginia—Two rescue teams slowly moved along a two-mile path on Monday night to the site of a coal mine explosion that trapped 13 miners, who had not been heard from since the early morning accident.
Meanwhile, at a nearby church, more than 250 family members and friends gathered, waiting for updates(最新报道)on the rescuers’ progress.
The miners were trapped at about 6:30 and many families weren’t informed of the accident until about 10 a.m-more than three hours after it happened. “It’s very upsetting, but you’ve got to be patient, I guess,” said John Helms, whose brother, Terry, was trapped in the mine.
The trapped miners were about 260 feet underground and about 10,000 feet from the Sago Mine’s entrance, said Roger Nicholson, general counsel from International Coal Group.
At a late night news conference, Nicholson said one team had advanced about 4, 800 feet in the four hours since entering the mine just before 6 p.m. Another team entered the mine about 30 minutes later.
He said the crew was very experienced, with some members having worked underground for
30 to 35 years. The miners were equipped with about one hour of breathable oxygen each. The company has not released the names of the miners.
The teams test the air about every 500 feet, and have to disconnect (remove) the power to the phones they use to communicate with the surface before doing that. “ We don’t want to be energizing anything if it’s in an atmosphere with burnable gases,” Kips said.
The cause of the explosion was not immediately known. High levels of carbon monoxide were detected shortly after the explosion, which delayed rescue efforts, but those levels have since subsided(减退), authorities said.
72. According to the passage, we can infer that ________.
A. all the miners who were trapped underground were still alive
B. communication with the trapped miners was cut off
C. the two rescue teams entered the mine at the same time
D. the rescue started as soon as the accident happened
73. If the first team advanced at an average speed, they could dig about _______ per hour.
A. 1,000 feet B. 2,400 feet C. 1,200feet D. 4,800feet
74. Where can the passage be seen?
A. In a magazine. B. In a newspaper.
C. In a science book.. D. On an advertisement.
75. Which of the following shows the position where the miners were trapped?
