智能训练练测考系列答案Humans have observed and explored the oceans since ancient times.But it wasn’t until the 19th century that the scientific study of oceans began.The first major scientific expedition,and the one that firmly established the field of oceanography,was the around-the-world voyage of H.M.S. Challenger.Setting out from England in 1872,the Challenger spent almost three and a half years gathering a wealth of information about seawater,sea life,and the ocean floor.Major oceanographic expeditions since then have included the South Atlantic voyage of the German ship Meteor in 1926 and the Deep-Sea Drilling Project from 1968 to 1983.Many individuals also have played important roles in advancing our understanding of oceans,beginning with Matthew Fontaine Maury in the mid-1800s;his work on oceanography and navigation led to a uniform system of weather reporting at sea.Since Maury’s time,oceanography has progressed rapidly.Early oceanographers had to contend themselves with tossing buckets overboard to see what they might haul in.Today’s oceanographers are equipped with space images,supercomputer models,and deep-sea robots that can crawl along the seafloor.As they set goals for the future,some oceanographers even dream of doing research in permanently manned stations on the bottom of the oceans.

People and the sources of air pollution are found in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major source of air pollution is the gas fumes from cars. Statistics show that 93 percent of all auto trips are within cities. Another major source of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the country.
On the average, we throw away more trash and garbage than the year before. The burning of garbage contributes to air pollution. Many major industries are also responsible for the dirty air in the around cities. The fumes from iron, steel, chemical, and petroleum production add particles to the air.
The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy for traffic may cause headaches for loss of clear vision. Wherever coal and oil are used for fuel, fumes may kill trees and plants and cause metal to corrode. In some of the larger cities, these fumes endanger the live of human beings by contributing to lung diseases and causing early death.
【小题1】The key point of the passage is that _________.
| A．the cause of air pollution is people |
| B．the causes and the effects of air pollution are both found in cities |
| C．the effects of air pollution range from headaches to death |
| D．air pollution is caused by dirty air |
| A．to persuade people to stop polluting the air |
| B．to tell the causes of air pollution |
| C．to tell why cities are bad places to live |
| D．to describe why cities are bad places to live |
| A．Because there are larger populations in cities. |
| B．Because the air in the city is dirty. |
| C．Because there are more cars in the city. |
| D．Because there are much more gas fumes from cars and burning of coal and oil for energy in the city than in the country. |
| A．to corrode | B．to twist |
| C．to turn black | D．to become rusty |
| A．heart disease | B．loss of clear vision |
| C．lung diseases | D．serious headache |
