[单项选择]Endangered Species
Endangered species are plants and animals that are in immediate danger of extinction. Extinction is actually a normal process in the course of evolution. Since the formation of the earth, many more species have become extinct than those exist today. These species slowly disappeared because of change of climate and their failure to adapt to such conditions as competition and predation. Since the 1600s, however, the process of extinction has greatly accelerated as a result of both human population growth and technological encroachment on natural ecology systems. Today the majority of the world’s environments are changing faster than the ability of most species to adapt to such changes through natural selection.
Species become extinct or endangered for number of reasons, but the primary cause is the destruction of natural habitats. Drainage of wetlands, cutting and clearing of forests, growth of cities, and highway and dam construction have seriously reduced avail
A. Human beings are not aware of the importance of preserving endangered species.
B. Some endangered species have already reached the end of their life span in evolution.
C. The development of human society has greatly affected natural ecology systems.
D. The world’s climate has changed greatly that most species cannot survive.

[单项选择]
When is an endangered species not an endangered species When it lives in the sea, apparently. Despite continuing carnage in the ocean, marine creatures were refused any protection at the United Nations conference on trade in wildlife that ended yesterday in Doha, Qatar.
Tigers, rhinos and elephants are all better protected after the meeting of the Convention on International Trade in Endangered Species (Cites). But hammerhead sharks, bluefin tuna and other marine species should be quaking in their skins. For when it comes to fish, the world has decided that scientific evidence of imminent demise is not reason enough to defend them against overexploitation. The conflict between trade and conservation is nothing new, but it is pretty well established that if you let trade in wildlife run rampant (蔓延的), soon there will be nothing left to sell. That is why the UN set up Cites in the first place.
