It’s true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There’s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: “The global warming over the last half-century has been caused mainly by human activity.”

You may not believe that humans could change the planet’s climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible (看不见的) blanket.

Of course, the earth’s climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth’s going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.

Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren’t carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”

The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.

1.In most scientists’ opinion, the global warming is mainly caused by ________.

A．solar activity B．volcanic activity

C．natural factors D．human factors

2.The text is developed by ________.

A．giving typical examples

B．following the order of space

C．changes in solar

D．floods and droughts

5.Which of the following can be the best title?

A．Are All the Scientists Really Scientific?

B．Where Is Global Warming Leading Us to?

C．Are Humans Definitely Causing Global Warming?

D．What’s the Relation of Global Warming and Greenhouse Gases?

An important scientific report announced “irrefutable（不能反驳的） proof” that climate change is happening and it’s all our fault. How long has it been before people are against the global warming idea? But here’s a funny thing. Last year there was a very bad hurricane season in the Caribbean when, among other disasters, New Orleans was all but wiped off the map. We were wisely informed by the experts at the time that this was owing to global warming.

I remember watching a BBC science programme and hearing a learned professor with a beard tell us, “The increased frequency and strength of hurricanes is what we shall have to learn to expect given global warming.”

This year there have been far fewer hurricanes and those there have been were relatively mild. Why？Global warming again of course. Professor Bjorn Lomborg, author of The Skeptical Environmentalist, writes, “In the constant media reports of possible greenhouse related disasters, almost any event is now linked to climate change.” He adds, “We should not spend vast amounts of money to cut a tiny slice of the global temperature increase when this leads to a poor use of resources and when we could probably use these funds far more effectively in the developing world.” For saying this, Lomborg has had death threats.

Other scientists who do not toe the global warming-is-happening-and-it’s-all-our-fault line have received the same. There are plenty of people who count against global warming. A world of senior climatologists and meteorologists wrote to the Times last year to complain that they couldn’t get their research findings published — because they disagreed to it. We have had a warm autumn. The experts, fanatics（狂热者） all of them, put it down to global warming. If we have an extra cold winter, they will tell us it’s a result of global warming. If my big toe feels cold or hurts badly, it will be owing to global warming.

B. people have realized the side effect of development

C. a different idea sometimes may cost one his life

D. the majority usually stand for the correct opinion

55. The main idea of the last paragraph may be ____.

A. global warming may lead to toe’s catching cold in a sense

B. the Times refuses to publish articles on global warming

C. a warming autumn is not related to global warming at all

D. it is certainly incorrect to owe everything to global warming

The new automobile fuel economy standards formally adopted by the Obama administration on Thursday will produce a series of benefits: reduced dependence on foreign oil, fewer greenhouse gas emissions(排放), and consumer savings at the pump.

This was truly a moment to celebrate. But it was tempered by the fact that some in Congress are trying to cancel the laws that made the new standards possible.

The standards will require automakers to build passenger cars, sport-utility vehicles and minivans that average 35.5 miles per gallon by 2016 — a 30 percent increase over today’s cars, and the biggest single jump in fuel economy since the original standards were adopted in the 1970s. Cars will cost more, but the government estimates that consumers will save an average of $3,000 in fuel over the life of a new vehicle.

The standards will also place the first-ever limits on automobile greenhouse gas emissions, and are expected to reduce emissions by 21 percent by 2030 compared with what the output would have been without the standards. Because emissions from passenger vehicles represent about one-fifth of America’s greenhouse gases, this is a step forward for the planet.

The automakers, who fought the rules until they went broke（破产）, have come to accept this as a step forward as well. A single national standard provides regulatory certainty, and they’ve got to get more efficient to survive.

However, some in Congress seemed determined to roll back the laws that got us here. Senator Lisa Murkowski, a Republican from Alaska, and several other senators have added a challenge to the federal government’s authority to regulate greenhouse gases under the Clean Air Act — not just from automobiles but from other sources. The Supreme Court gave the Environmental Protection Agency that authority three years ago, and the new emissions standards would have been impossible without it.

There has also been talk in the Senate of eliminating California’s special authority under the Clean Air Act to set more aggressive motor vehicle standards than the federal limits. California used that authority to pass a law in 2002 setting greenhouse gas emissions limits for cars sold there. It was the first law of its kind in this country, and it provided the drive and the foundation for the new nationwide standards.

What all of these opponents mean to do is to roll back history and the hard-won environmental protections it has produced. That would be a huge mistake.

66. The following are the benefits of the new automobile economy standards EXCEPT ________.

A. reduced dependence on foreign oil

B. cancelling some of the laws

C. fewer greenhouse gas emissions

D. consumer savings at the pump

67. What goal is set for the year 2016?

A. Cars will cost more so fewer people will buy them.

B. There is a 30 percent increase in car manufacturing.

C. An average vehicle can go 35.5 miles with one gallon of gas.

D. Consumers will save an average of $3,000 in fuel per car.

68. The underlined word “it” in paragraph six refers to ________.

A. The Clean Air Act

B. The Supreme Court

C. The Environment Protection Agency

D. The federal government’s authority

69. What seems to be the root of the new automobile fuel economy standards?

A. California’s motor vehicle standards.

B. The Environment Protection Agency.

C. Some Senators, like Lisa Murkowski.

D. Greenhouse gas emissions.

70. According to the writer, the new automobile fuel economy standards will probably lead to the result that ________.

A. everyone wins

B. more cars will be sold

C. it would be a big mistake

Astronauts’ meals have come a long way from the free-dried powders and semi—liquid pastes of decades ago，now US scientists want to grow vegetables in mini—greenhouses on the moon．

Scientists say they are looking forward to a time when residents of future lunar or even Martian outsteps will be able to dine on fresh vegetables．Paragon Space Development Corporation has unveiled what it called the first step toward growing flowers——and eventually food on the moon．

This is a sealed greenhouse that looks like a bell jar encased in a 46-cm triangular aluminiumframe．It is designed to safely land a laboratory plant on the lunar surface，and protect it while it grows．

The miniature greenhouse is to be launched into space by Odyssey Moon Ltd, a participant in the Google Lunar X Prize. This competition offers $21 million to any entrant who can launch, land and operate a rover on the lunar surface.

Paragon officials say future testing of the “Lunar Oasis” will be driven by Odyssey’s flight Schedule, which will not happen until 2012 at the earliest．

When it does lift off the greenhouse will contain the seeds of Brassica, a hardy plant related to Brussels sprouts and cabbage. Because Brassica goes from seed to flower in just 14 days, it can complete its life cycle in a single lunar night.

“Colonizing the Moon or Mars seems so far away，but it is important that we do this research now. ”Paragon president Jane Poynter said．

“It takes a long time to get a lot of research, and to get integrated, reliable efficient systems before colonists move in. ”she said．

1.The article is written mainly to__________．

A. predict the astronauts’ meals in the future

B. introduce an experiment “Lunar Oasis’’

C. tell us the future development of astronomy

D. focus on the human’s great progress

2.The article implies that__________．

A. astronauts can grow flowers in space at present

B. Paragon and NASA will carry out the test separately

C. Lunar Oasis is a series of experiments carried out in space

D. the earliest testing of the Lunar Oasis may be in 2012

3.The underlined word “colonists” in the last paragraph probably has the meaning of______．

A. plants B. wild beasts C. human beings D. scientists

4.The seeds of Brassica will be contained in the greenhouse mainly because _________.

A. their life cycle is much shorter

B. they are more nutritious than other food

C. they are related to Brussels sprouts and cabbage

D. they are very delicious
