Ⅵ.阅读理解
Many environmental groups are warning that oceans of the world are in great danger. In the past 50 years, the number of water with zero oxygen(氧气) in the open ocean has increased more than four times. In the near coast water bodies, including the river mouth and seas, low oxygen areas have increased more than 10 times since 1950. Scientists discover that oxygen continues dropping even outside these zones as the Earth warms. To stop the drop, the world needs to control in both climate change and nutrient(养分) pollution.
Oxygen is a must to life in the oceans. The drop in ocean oxygen is among the most serious effects of human activities on the Earth's environment.
This is the first time that the scientists take such a deep look at the causes, results and solutions to low oxygen worldwide, in both the open ocean and the near coast waters. About half of the oxygen on the Earth comes from the ocean. However, mixed effects of nutrient loading and climate change are greatly increasing the number and size of “dead zones” in the open ocean and the near coast waters, where oxygen is too low to support most sea life.
In the areas traditionally called “dead zones”， like those in Chesapeake Bay and the Gulf of Mexico oxygen drops to levels so low that many animals have trouble in breathing and die. As fishes run away from these zones, their living areas become smaller and smaller. But the problem goes far beyond “dead zones”. Even smaller oxygen drops can hold up the growth in animals and lead to disease or even death. Low oxygen can also cause the release of dangerous chemicals. Although a few animals can grow well in dead zones, overall biodiversity(多样性) falls.
(　　)36.How to stop the drop of ocean oxygen in the article
A．By controlling in both climate change and nutrient pollution around the world.
B．By taking a deep look at the causes, results and solutions to low oxygen worldwide.
C．By running away from these zones, for the living areas become smaller and smaller.
D．By cutting down the number of animals in the oceans.
(　　)37.Why are these waters called “dead zones” from the article
A．Because the oxygen in these areas is too low for most sea life to live.
B．Because nutrient loading and climate change are greatly increasing.
C．Because there are no animals living in these areas.
D．Because low oxygen can also cause the release of dangerous chemicals.
(　　)38.Which of the following statements is TRUE according to the article
A．Only a few animals living in the sea need oxygen.
B．Climate change can help cut down the dead zones.
C．Fishes grow faster and better in low oxygen areas.
D．Human activities have many serious effects on ocean environment.
