【题目】 To address the plastic pollution troubling the world’s seas and waterways, Cornell University chemists have developed a new polymer (聚合物) that can degrade (降解) plastic when exposed to ultraviolet radiation, according to the research published in the Journal of the American Chemical Society.

“We have created a new plastic that has the mechanical properties required by commercial fishing gear. If it eventually gets lost in the water environment, this material can degrade on a realistic time scale,” said lead researcher Bryce Lipinski, professor of chemistry and chemical biology at Cornell University. “This material could effectively reduce persistent plastic accumulation in the environment.”

Commercial fishing contributes to about half of all floating plastic waste that ends up in the oceans. Fishing nets and ropes are primarily made from three kinds of polymers, none of which easily degrade. “While research of degradable plastics has received much attention in recent years,” Lipinski said, “obtaining a material with a mechanical strength comparable to commercial plastic remains a difficult challenge.”

Coates and his research team have spent the past 15 years developing the new plastic called isotactic polypropylene oxide, or iPPO. While its original discovery was in 1949, the mechanical strength of this material was unknown before this recent work. The high isotacticity and polymer chain length of their material makes it different from previous plastics and provides its mechanical strength.

Lipinski and other scientists want no race of the polymer to be left in the environment. He notes there is precedent (先例) for the biodegradation of small chains of iPPO which could effectively make it disappear and ongoing efforts aim to prove this.

【1】What is the feature about the new polymer?

A.It can solve the problem of plastic consumption.

B.It can degrade plastic waste in the sea water.

C.It has been developed to solve plastic pollution.

D.It has been developed to lower fishing costs.

【2】What can we infer from paragraph 3?

A.It requires great effort to invent the new plastic.

B.Fishing should be forbidden in the sea.

C.Fishing nets and ropes are not the major pollution source.

D.Degradable plastics were not paid attention to until recent years.

【3】What did the recent study find about iPPO?

A.Its original discovery.B.Its mechanical properties.

C.Its complex structure.D.Its mechanical strength.

【4】What is Lipinski’s attitude towards the future of iPPO?

A.Doubtful.B.Promising.

C.Unconcerned.D.Disapproval.

【题目】 At the World Economic Forum last month, President Trump drew claps when he announced the United States would respond to the forum's proposal to plant one trillion(万亿) trees to fight climate change. The trillion-tree idea won wide attention last summer after a study published in the journal Science concluded that planting so many trees was “the most effective climate change solution to date”.

If only it were true. But it isn't. Planting trees would slow down the planet's warming, but the only thing that will save us and future generations from paying a huge price in dollars, lives and damage to nature is rapid and considerable reductions in carbon release from fossil fuels, to net zero by 2050.

Focusing on trees as the big solution to climate change is a dangerous diversion(偏离). Worse still, it takes attention away from those responsible for the carbon release that are pushing us toward disaster. For example, in the Netherlands, you can pay Shell an additional 1 euro cent for each liter of regular gasoline you put in your tank, to plant trees to balance the carbon release from your driving. That's clearly no more than disaster slightly delayed. The only way to stop this planet from overheating is through political, economic, technological and social solutions that end the use of fossil fuels.

There is no way that planting trees, even across a global area the size of the United States, can absorb the huge amounts of fossil carbon released from industrial societies. Trees do take up carbon from the atmosphere as they grow. But this uptake merely replaces carbon lost when forests were cleared in the first place, usually long ago. Regrowing forests where they once grew can undo some damage done in the past, but even a trillion trees can't store enough carbon to head off dramatic climate changes this century.

In a sharp counter argument to last summer's Paper in Science, Justin Gillis wrote in the same journal in October that the study's findings were inconsistent with the dynamics of the global carbon cycle. He warned that “the claim that global tree restoration(复原) is our most effective climate solution is simply scientifically incorrect and dangerously misleading”.

【1】What do we know about the trillion-tree idea?

A.It was published in a journal.

B.It was proposed last summer.

C.It was put forward by Trump.

D.It drew lots of public attention.

【2】What is paragraph 3 mainly about?

A.A drawback of the tree planting strategy.

B.An example of balancing carbon release.

C.An anecdote of making a purchase at Shell.

D.A responsibility for politicians and economists.

【3】What was Justin Gillis's attitude towards global tree restoration?

A.Indifferent.B.Opposed.

C.Hesitant.D.Supportive.

【4】What is the best title for the text?

A.Contradictory Ideas on Tree Planting.

B.A Trillion Trees Come to the Rescue.

C.Planting Trees Won't Save the World.

D.The Best Solution to Climate Change.

【题目】 When I was a child growing up in Ohio, the butterflies would sometimes pass through on their way to Mexico. And it was awesome to see football fields full of them — and I wanted to revisit that on a larger scale. I knew I had to go to see the migration in Mexico.

But I was on a budget. I didn’t want to rent a car in Mexico or take a bus to Valle de Bravo, the starting point for most butterfly adventures, so I called the guys at the Muddy Boot, travel experts in Mexico who can make almost anything happen at a reasonable rate.

And so, on January 2, I found myself in the Muddy Boot van (货车), being driven two hours from Mexico City to Valle de Bravo, a lovely town on a volcanic lake which is a central point for the butterfly journeys. I booked a two-night stay at the Hotel Rodavento, an all eco-friendly hotel with individual wooden houses spread throughout the forest and around a lake.

The first sanctuary (保护区) I visited was Piedra Herrada, a popular destination, as it is only 40 minutes away from Valle de Bravo. The climb up is tiring. It is advisable to hire a horse. But the horse cannot take you all the way, and there is some hiking in thin air, so you must be patient, drink a lot of water, and be in reasonably good shape.

The walk is more than worth it, though. As I struggled to catch my breath, I looked up and lost my breath again. At first glance, the trees had turned into different shapes, but on closer inspection, every inch of them was covered with butterflies.

A few flew through the air (Most of them were not warm enough). As the sun rose, they began to come alive. Soon the air was filled with flying butterflies, transforming the forest into something magical and straight out of a fairy tale.
