16．When you think of environmental problems you probably think of pollution，but the poaching （偷獵） of wild animals is one，too．Poaching has worried environmentalists for years and，despite laws，this terrible crime has yet to be stopped．
Poaching is a serious problem，especially in Africa and Asia．This crime is done for commercial profit （商業(yè)利益），meaning hunters kill animals illegally and sell their most worthy parts．Although poachers usually hunt tigers，elephants and rhinos，they kill sharks and whales，too．This illegal hunting has led to decreasing populations of many species（物種）．
Many nations have banned poaching，but enforcement （執(zhí)行） is difficult．The small number of police officers trained to deal with this creates an unfair advantage for poachers．
Poachers usually kill animals for only one product：tigers are killed for their striped fur，elephants their ivory tusks and rhinos their large horn．The bodies of the animals are left to rot．Sharks'fins are cut off and their bodies thrown back into the ocean．Without fins they can't swim and will die．The illegally obtained fins are used to make shark fin soup．
The laws that"protect"animals are no more than pieces of paper．The current poaching bans （禁令）need better enforcement，and I have a plan．
The number of enforcers needs to be increased so that there are enough to watch the herds（獸群） and make sure poachers can't shoot the animals．The reserve parks in Africa should become a huge zoo so that the animals can move but within a fenced area．Another idea is to build a concrete enclosure instead of fences．Watchtowers could be constructed so enforcers can monitor a wide variety of poacher targets．This may not completely end the problem，but it would slow it down．
Poaching is a serious problem and a criminal act．（犯罪） The effects of poaching will be felt for centuries to come，and if there are any still alive，the only place to see animals might be in a zoo．

分析 本文是一篇議論文，以偷獵的現(xiàn)象展開(kāi)討論，敘述了此現(xiàn)象出現(xiàn)的原因，其對(duì)自然環(huán)境的嚴(yán)重危害，以及更好禁止此現(xiàn)象的建議．偷獵是嚴(yán)重的犯罪行為，其對(duì)自然環(huán)境的破壞巨大，我們嚴(yán)厲打擊這種行為，保護(hù)我們的環(huán)境．
解答 72．答案：C．細(xì)節(jié)理解題．根據(jù)"Poaching has worried environmentalists for years and，despite laws，this terrible crime has yet to be stopped．"可知，偷獵被法律禁止了．故選C．
73．答案：A．細(xì)節(jié)理解題．根據(jù)"This crime is done for commercial profit （商業(yè)利益），meaning hunters kill animals illegally and sell their most worthy parts"可知，人們偷獵是為了獲取經(jīng)濟(jì)利益．故選A．
74．答案：A．推理判斷題．根據(jù)"Poaching is a serious problem and a criminal act．（犯罪） The effects of poaching will be felt for centuries to come，and if there are any still alive，the only place to see animals might be in a zoo．"知，偷獵是很?chē)?yán)重的問(wèn)題，其影響要經(jīng)過(guò)很長(zhǎng)時(shí)間才能消除，如果偷獵的現(xiàn)在還在存在，那么以后唯一能看到動(dòng)物的地方就是動(dòng)物園了．可推測(cè)出，如果不禁止的話，偷獵會(huì)更嚴(yán)重．故選A．
75．答案：B．主旨大意題．根據(jù)全文內(nèi)容知，文章圍繞偷獵現(xiàn)象展開(kāi)討論，提出了一些禁止偷獵的建議．故選B．
點(diǎn)評(píng) 本文是一篇議論文，題目涉及細(xì)節(jié)理解題，推理判斷題，主旨大意題，做題時(shí)應(yīng)結(jié)合文章上下文內(nèi)容并根據(jù)所給選項(xiàng)的含義進(jìn)行分析，從而得出正確答案．切記胡亂猜測(cè)，一定要做到有理有據(jù)．
