四、阅读理解 In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, 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 Earth warms.
“Oxygen is fundamental to life in the Oceans,” said Denise Breitburg, a marine ecologist with the Smithsonian Environmental Research Centre. “The decline in ocean oxygen ranks among the most serious effects of human activities on the Earth’s environment. Actually, it’s a great loss to all the support services that rely on recreation and tourism, including hotels and restaurants and taxi drivers and everything else. The reverberations(严重影响) of unhealthy ecosystems in the ocean can be extensive.”
extensive 美 [ k stens v] adj.广阔的;广大的;大量的;广泛的;宽广;广博的;广搏
In areas traditionally called “dead zones”, like those in Chesapeake Bay and the Gulf of Mexico, oxygen plummets(大幅下跌) to so low levels that many animals die. As fish avoid these zones, their habitats become smaller and they’re easier to 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 can also cause the release of dangerous chemicals such as nitrous oxide,a greenhouse gas up to 300 times more powerful than carbon dioxide.While some animals can boom in “dead zones”, overall biodiversity falls.
hinder [ h nd r] v.阻碍;妨碍;阻挡
adj.后面的
阻止;妨害;关碍
nitrous oxide [ na tr s ɑk sa d]
n.氧化亚氮
一氧化二氮;笑气;一氧化氮
boom [bum] n.繁荣;吊杆;(某种体育运动、音乐等)突然风靡的时期;帆桁
v.激增;繁荣昌盛;轰鸣;轰响
adj.〈美〉猛涨起来的
隆隆声;兴旺;景气
adj.+n. economic boom,postwar boom,sales boom
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 oxygen. In coastal waters, too much nutrient pollution from land creates algal blooms, which use up oxygen as they die and break down.
People’s livelihoods are also on the line, the scientists reported, especially in developing nations. Smaller fisheries(渔场) may be unable to relocate when low oxygen destroys their harvests or forces fish to move elsewhere. So we humans have to carry on a war now and win the war.
algal blooms
on the line
na.立即;(挂)在不高不低的地方;模棱两可;处于危险状态

Everyone knows animals are our friends. But many animals are facing the danger of extinction, because the environment that they are living in has been destroyed greatly. What’s worse, human race is killing them just for getting their fur, skin, teeth and meat. In order to protect our resources of ecology, our government should pass laws and forbid people to hunt the animals in danger. We can work together to plant more trees and call for protecting animals’ habitats. At the same time, it is necessary to have long-term projects to help the endangered animals. Only if we protect animals well can we have a bright future!(共16张PPT)

Following China’s reform and opening-up in the 1980s, Pingyao struggled with the change from a managed economy to the market-oriented economy (市场经济). During this time, the city government identified new ways to break through this economic bottleneck.
Finally in the winter of 1997, chances came knocking. Through the efforts of the city government, Pingyao earned its place on the UNESCO World Heritage list, which caused the entire world to take notice of the city.
Since the city’s fame has risen, locals in Pingyao have deepened their understanding of the efforts preserving the historical relics in their hometown. Meanwhile the city government has continued to upgrade itself through a proposal that follows the centre of “entrepreneurship (创业), development and protection”.
Recently, the city is focused on establishing a sustainable (可持续发展) industry that will enable it to continue to grow while also protecting its relics and introducing them to the world.

Ⅴ.阅读理解 A new study has found that North American migratory(迁徙的) birds have been getting smaller over the past 40 years. Researchers say the finding suggests a warming climate(气候) could be affecting bird growth in North America—and across the world.
The study was recently published in Ecology Letters. Researchers measured(测量) the size of 80,000 birds killed from 1978 to 2016 during the spring and fall migrations in the city of Chicago, Illinois. Over the 40-year period, body size decreased in all 52 species. The average body weight fell by 2.6 percent. Leg bone length dropped by 2.4 percent. The one area of growth was the wingspan, which increased by 1.3 percent.
The researchers said the wing growth likely happened to allow the birds to continue making long migrations with smaller bodies. The study considered a principle known as Bergmann’s rule, in which individuals within a species grow smaller in warmer areas and grow larger in colder ones.
Brian Weeks, a biologist at the University of Michigan’s School for Environment and Sustainability, helped lead the research. He said that he believes the results show a clear connection between a warming climate and the growth of the birds. “In other words, climate change seems to be changing both the size and shape of these species,” he said.
The study found a direct connection between the average summer temperature and the body size of the birds. Dave Willard works with Chicago’s Field Museum, which was in charge of measuring all the birds. He said nearly “everyone agrees that the climate is warming, but examples of just how that is affecting the natural world are only now coming to light.”
“We had good reason to expect that increasing temperatures would lead to reductions in body size, based on earlier studies,” Weeks said.“I was incredibly surprised that all of these species are responding in such similar ways.”
The researchers plan to continue studying the Field Museum data in an effort to find additional evidence to support their findings.They will also further examine the idea that an individual’s physical development can change to fit changing environmental conditions.
1.Which of the following didn’t go down to a lower level
A.The body size.
B.The body weight.
C.The leg bone length.
D.The wingspan.

2.Which of the following took responsibility for measuring the birds
A.Ecology Letters. B.Brian Weeks.
C.The Field Museum. D.Dave Willard.
3.What do the underlined words “coming to light” in paragraph 5 mean
A.Known.      B.Similar.
C.Intelligent. D.Distant.
4.The main idea of the passage is that   .
A.fifty-two species of birds became smaller
B.the warming climate could affect bird growth
C.the warming climate makes the birds grow larger
D.the researchers have proved their findings

Dear teachers and students,  Air pollution is serious these days, which does great harm to our health. What should we do   Firstly,we should take a bus or ride a bicycle instead of driving a car and try to use cleaner fuels. Secondly,we should not throw litter here and there but put it into the dustbin. Thirdly,some factories should be closed or move out of the city. Finally,we need to plant more trees or grass to make the air fresh.  Let’s take action and try our best to make the air in the city cleaner!  Thank you! The Students’ Union
