4、 had made hot and cold chocolate drinks with spices.二、七选五Urban WildlifeCities are diverse ecosystems. In addition to visitors, a large number of species share our urban areas. As our cities spread, we need to think about what it is like for other species to have human neighbors.Cities are built for

5、humans.For example, most city parks are kept neat and tidy so that humans will find them beautiful. But when we cut grass or plants, we destroy natural habitats, which leads to the imbalance of ecology.When a bridge in Austin, Texas was repaired, engineers added small gaps running along the length o

6、f its bottom. This made a good home for bats, and soon the bridge was home to thousands of bats. (3)Now, they have e to value their winged neighbors. The bats bee a tourist attraction, and they eat lots of bugs every night.There are also structures built with the aim of bringing wildlife into the ci

7、ty. The Beijing Olympic Forest Park is a good example. The park used native plants, and created open and natural spaces for wildlife. The result is a zone in Beijing with over 160 species of birds.

In coastal water bo

10、dies, including river mouths and seas, low-oxygen sites have increased more than tenfold since 1950. Scientists expect oxygen to continue dropping even outside these zones as the Earth warms.Oxygen is fundamental to life in the ocean,n said Denise Breitburg, a marine ecologist at the Smithsonian Env

11、ironmental Research Center. nThe decline in ocean oxygen ranks among the most serious effects of human activities on the Earths environment. Actually, its a great loss to all the support services that rely on recreation and tourism, including hotels, restaurants, taxis and everything else. The rever

12、berations （影响）of unhealthy ecosystems in the ocean can be extensive.”In areas traditionally called Hdead zones11, like those in Chesapeake Bay and the Gulf of Mexico, oxygen plummets（暴跌）to so low levels that many animals die. As fish avoid these zones, their habitats bee smaller and theyre easier to

13、 be attacked or caught. But the problem goes far beyond dead zones”. Even smaller oxygen decline can prevent growth in animals, hinder reproduction and lead to disease or even death. It also can cause the release of dangerous chemicals such as nitrous oxide, a greenhouse gas up to 300 times more pow

14、erful than carbon dioxide. While some animals can boom in dead zones1, overall biodiversity falls.Climate change is the key criminal in the open ocean. Warming surface waters make it harder for oxygen to reach the inside of the ocean. Furthermore, as the ocean as a whole gets warmer, it holds less o

15、xygen. In coastal waters, too much nutrient pollution from land creates algal blooms, which run out of oxygen as they die and break down.Peoples livelihoods are also on the line, the scientists reported, especially in developing nations. Smaller fisheries （渔场）may be unable to relocate when low oxyge

16、n destroys their harvests or forces fish to move elsewhere.

24、过去的50年里，海洋中零氧水域的水量增 加了四倍多。低氧场所自1950年以来增加了十多倍。通过这些现状，科学家预计，随着地球变暖，即 使在这些区域之外,氧气也会继续下降。由此可知海洋正在失去氧气。故选A。2 .推理判断题。根据第二段 Denise Breitburg 说的 Oxygen is fundamental to life in the ocean 和 The decline in ocean oxygen ranks among the most serious effects of human activities on the Earths environment. The re

25、verberations（影响）of unhealthy ecosystems in the ocean can be extensive.可知，海洋 氧气的减少是人类活动对地球环境最严重的影响之一,这种不健康的海洋生态系统的影响还会扩 大。由此可见海洋氧气的减少有很大影响。故选B。3 .细节理解题。根据第三段中的 In areas traditionally called ndead zones”oxygen plummets（暴跌）to so low levels that many animals die. As fish avoid these zones, their habitats bee smaller and theyre easier to be attacked or caught.可知，死亡地带”的氧气大幅下跌,导致许多动物死去。当鱼类避开这些区域 时，它们的栖息地变小，使它们更容易被攻击或捕获。故选Co.推理判断题。根据第二段中的 The decline in ocean oxygen ranks among the most serious effects.taxis and everything else.可知，是人类活动造成了海洋氧气减少，所以要解决此问题必须控制 人类的有害活动。故选B。
