【题目】Scientists have long understood the key role that oceans play in regulating the Earth’s climate. Oceans cover 70 percent of the globe and store a thousand times more heat than the atmosphere does. What’s newer is the understanding of how this key component of our climate system responds to global warming.
A brake on global warming — for now
One of oceans’most important climate functions is absorbing heat and carbon dioxide (CO2), one of the gases that cause global warming. Acting as a heat sponge (海绵), oceans have absorbed huge amounts of heat and CO2 in the last forty years.
Fujita explains that "oceans are saving us from faster climate change — they are a big flywheel that delays rapid overheating of the Earth, putting a brake on the climate system."
"That’s the good news," he adds. "The bad news is that oceans only slow the atmospheric warming. Once oceans come to balance with a greenhouse gas warmed earth, the extreme heat will remain in the atmosphere and things will get much hotter." But where and how oceans release this accumulated (积累的) heat is uncertain. And as oceans store heat, fragile underwater ecosystems are struggling.
The most recent scientific report from the Intergovernmental Panel on Climate Change (IPCC) also notes with concern that oceans are acidifying because of increased absorption of atmospheric CO2, and thus causing a threat for shell-forming species. Sharp increases in carbon dioxide levels will cause further acidification of oceans.
Currents distributing heat
Another important role oceans play is that of distributor. Oceans deliver heat and life-sustaining nutrients around the globe. Just as blood vessels bring oxygen and nutrients to cells in the human body, oceans’ currents carry oxygen, nutrients and heat throughout the Earth. Oceans distribute 25 percent to 50 percent of the energy the planet receives from the sun. For example, the Gulf Stream carries heat across the Atlantic. This warm current gives northwestern Europe a milder climate than it would normally have so far north. A change to oceans’ circulation (循环) patterns could throw Europe into a colder period, even as the rest of world experiences warmer temperatures.
【1】We can infer from the passage that .
A.oceans cause global warming
B.oceans stop global warming
C.oceans release nutrients and heat
D.ocean ecosystems face more dangers
【2】From the passage we can learn that oceans’ currents .
A.produce oxygen and nutrients everywhere
B.absorb 25% to 50% of the energy from the sun
C.distribute heat and nutrients around the globe
D.change oceans’ circulation patterns
【3】Which of the following is NOT the result of oceans absorbing heat and carbon dioxide?
A.It causes further acidification.
B.It affects shell-forming species.
C.It makes the atmosphere hotter.
D.It regulates the Earth’s climate.
【4】This passage mainly talks about .
A.the roles of oceans B.global warming
C.ocean currents D.carbon dioxide

【题目】The National Geographic Channel has unearthed a time capsule (时光宝盒) buried by late Apple chairman and co-founder Steve Jobs thirty years ago.
The time capsule was buried in Aspen, Colorado, in 1983, shortly after Jobs attended the International Design Conference being held in that city. Organizers called the device the Aspen Time Tube and contributed items like Rubik's cubes(魔方) and some iconic music. Jobs added his own items to the capsule, including the " Lisa" ( also known as an "Apple" ) mouse" he used for his presentation at the conference.
Younger readers may not recognize the name but the Lisa Apple mouse was one of the first commercial mice released to consumers. The mouse was specially designed for the Apple Lisa computer. It's also the first personal computer to offer users a graphical user interface(图形用户界面)
Initially, the plan was to dig up the time capsule in the year2000, but organizers forgot its exact location. Recently, they brought in researchers working with the National Geographic Channel show Diggers to find the device. Eventually they came across the 13-foot-long, 1.5-foot-diameter tube. Inside they found a lot of 1980s artifacts(人工制品)that are still being catalogued.
“When the end came off, literally things just poured out.” noted Diggers host Tim Saylor "There must be literally thousands of things in there.”
“They had the foresight to put a bunch of stuff in plastic bags." Saylor said. “I could see at least a dozen plastic bags and other items. But I know for sure there got to the photographs in there. /span>People had hand-written things on the back of the photographs, so there will be some really interesting things inside.”
Among the artifacts researchers expect to discover inside: a Steve Jobs speech in which the Apple visionary outlines his predictions for future technologies. We should know more about the researchers, discoveries once the Diggers program airs this fall.
【1】Which of the following is true about the Lisa mouse?
A. The mouse was the first commercial one for consumers.
B. The mouse was created only for the Apple Lisa computer.
C. The mouse was buried in Aspen, Colorado for two decades.
D. The mouse was invented after the International Design Conference.
【2】Why wasn't the time capsule dug up in 2000?
A. Because it was not the time set by Steve Jobs.
B. Because it could not be accurately located.
C. Because organizers forgot its precise shape.
D. Because the local government didn't approve.
【3】From the passage we can infer that_______.
A. there were some special photographs found-inside the time capsule
B. a Steve Jobs speech with future predictions was found inside the cap
C. Steve Jobs predictions for future technologies have come true
D. more about the capsule will be discovered in the Diggers program
【4】The best title for the passage might be _______.
A. The "Lost" Steve Jobs Time Capsule
B. The Mystery of Steve Jobs Speech Solved
C. Steve Jobs' 1983 Time Capsule Recovered
D. Co-founder & Former Apple CEO Steve Jobs

【题目】If you really want to go green, here’s good news: eating green is good for you. The very foods with a high carbon cost---meat, pork, dairy products, processed snacks---also tend to be filled with fat and calories. A green diet would be mostly vegetables and fruits, whole grains, fish and lean meats like chicken---a diet that’s eco- and waistline-friendly. Eating green can be healthier and beneficial to the climate.
It may be hard to believe that a meal at McDonald’s produces more carbon than your trip to a far away place. More than 37% of the world’s land is used for agriculture, much of which was once forested. Deforestation (砍伐森林) is a major source of carbon. The fertilizer (化肥) and machinery needed on a modern farm also have a large carbon footprint, as does the network of ships and trucks that brings the food from the farm to your plate.
The most efficient way to reduce the carbon footprint of your menu is to eat less meat, especially beef. Raising cattle takes a lot more energy than growing the equivalent (相等的) amount of grains, fruits or vegetables. What’s more, the majority of cattle in the U.S. are fed on grain and loads of it---670 million tons in 2002---and the fertilizer used to feed that creates separate environmental problems.
Focus on eating lower on the food chain, with more plants and fruits and less meat and dairy. It’s simple. We can change today what goes into our bodies for the health of our planet and ourselves.
【1】According to the passage, eating green will_____.
A. protect the animals from being killed
B. promote the development of agriculture
C. help us lose weight and keep self-confidence
D. be good for our health and make a change for the climate
【2】What will not lead to carbon in the agriculture?
A. Deforestation B. Fertilizer
C. Machinery D. Grains
【3】In the author’s opinion, the most efficient way to reduce carbon is to_____.
A. eat more vegetables than meat
B. stop raising the cattle
C. plant more grains
D. use less fertilizer
【4】What is the passage mainly about?
A. The benefits of eating green.
B. How to reduce the carbon.
C. The change of our menu.
D. The ways of keeping healthy.
