Due to climate change, Arctic ice is breaking up earlier in the spring, and its area is decreasing. This is creating problems for polar bears that make their homes off northern Alaska and in Hudson Bay.

Polar bears off Alaska normally hunt and raise their young on ice sheets that float on the ocean. But as the ice has melted, the polar bears have been forced to spend more time on land. There, they have begun to frequent beaches, feeding on the remains of whales caught by native hunters. For polar bears, this food is less nutritious than seals that they normally catch on ice sheets. The shrinking（减少） ice has also forced more polar bears into the ocean. In the past, they only had to swim short distances between ice sheets. But as the ice has shrunk, polar bears have been forced to swim longer and longer distances in the open ocean. This poses a severe danger during rough weather, and an increasing number of drowned polar bears have been observed.

In Hudson Bay, the ice breaks up three weeks earlier in the spring now than it did 20 years ago. Polar bears on Hudson Bay fast（绝食） during the summer, waiting for ice to form in the fall to hunt. Every year, the summer gets longer, and the bears get skinnier. Over the past 25 years, the average weight of the female bears has dropped 68 kg. This loss affects their ability to reproduce, and already the number of births has dropped 15 percent. Unless the bears can learn to survive these climate changes, these giants of the ice may one day disappear.

1.What is Arctic ice doing earlier each year?

2.What is true of polar bears that are spending more time on land in Alaska?

3.What do polar bears in Hudson Bay do during the summer?

4.In which publication would you most likely find this passage?

Is there link between humans and climate change or not? This question was first studied in the early 1900s. Since then, many scientists have thought that our actions do make a difference. In 1997, the Kyoto Protocol explained our role in the Earth’s changing atmosphere and set international limits for gas emissions（排放）from 2008 to 2012. Some countries have decided to continue these reductions until 2020. More recently, the Paris Agreement, stuck by nearly 200 countries, also aims to limit global warming. But just now how much warmer it will get depends on how deeply countries cut carbon emissions.

3.5℃: This is how much temperatures would rise by 2100 even if nations live up to the initial Paris promises to reduce carbon emissions; this rise could still put coastal cities under water and drive over half of all species to extinction.

2℃: To meet this minimum goal, the Agreement requires countries to tighten emissions targets every five years. Even this increase could sink some islands, worse drought and drive a decline of up to a third in the number of species.

1.5℃: This is the most ambitious goal for temperature rise set by the Paris Agreement, after a push by low-lying island nations like Kiribati, which say limiting temperature rise to 1.5℃ could save them from sinking.

0.8℃: This is how much temperatures have risen since the industrial age began, putting us 40% of the way to the 2℃ point.

0℃: The baseline here is average global temperature before the start of the industrial age.

1.It can be concluded from Para.1 that _______.

A. the problem of global warming will have been quite solved by 2020

B. gas emissions have been effectively reduced in developed countries

C. the Paris Agreements is more influential than the Kyoto Protocol

D. humans have made continuous efforts to slow down global warming

2.If nations could only keep the initial promises of the Paris Agreement, what would happen by the year 2100?

A. The human population would increase by one third.

B. Little over 50% of all species would still exist.

C. The Agreement’s minimum goal would not be reached.

D. Nations would not need to tighten their emissions targets.

3.If those island nations not far above sea level are to survive, the maximum temperature rise, since the start of the industrial age, should be_______.

A. 0.8℃　　 B. 1.5℃　　 C. 2℃　　 D. 3.5℃

Climate change will increase US wildfires,and the smoky air will cause terrible problems in areas far beyond those burned,reports an environmental group Thursday.

Two-thirds of Americans,or nearly 212 million,lived in states suffering from wildfire smoke three years ago,according to the report by the Natural Resources Defense Council(NRDC).These areas,which had smoke for at least a week,were nearly 50 times greater than those burned directly by fire.

“It affects a much wide area of the United States than people have realized.” says author Kim Knowlton,a Columbia University health professor,adding the smoke can move up to hundreds of miles.She says the smoke contains air pollution and can cause several kinds of diseases.

Texas was hit hardest in 2011,when smoke stayed for at least a week in areas that are home to 25 million people,according to NRDC’s report.Illinois,which recorded no wildfires within its borders, came second with nearly 12 million people affected by smoke that moved in from elsewhere.The other eight states with the most people in touch with smoky air were,in descending　 order: Florida,Missouri,Georgia,Louisiana,Michigan,Alabama,Oklahoma and Iowa.

Nearly two dozen states had no wildfires within their borders in 2011,but eight of them still had at least one week of smoky air: Illinois,Missouri，Iowa,Kansas,Nebraska,Indiana,Wisconsin and Ohio.

Only 18 states and the District of Columbia had no people in touch with at least a week of smoke that year,although five of them—Alaska,California,Hawaii,Nevada and Utah—had a large area burned by wildfires.

The problem will only get worse.Knowlton says.Scientific research shows climate is causing higher temperatures and health problems.
