52.There are many interesting news items in BP’s(英国石油公司)annual Energy Outlook just published. But perhaps the most astonishing suggestion in the report is the idea that cutting back on plastic use could make matters worse. This might be what you would expect BP to say. After all, as one of the world’s biggest oil companies, it makes a lot of money from selling products in plastic. But let’s look at the thinking behind BP’s argument.If the current opposing idea about the use of plastic continues, there could be a worldwide ban on single-use plastics by 2040. But the document argues that switching plastic for other materials will have a bigger cost in terms of energy and carbon emissions(排放). That sounds like the law of unintended(非故意的)consequences in action. When plastic bags are measured against paper or cotton substitutes, a BBC analysis found there wasn’t a great deal of difference in their environmental impact. Paper bags require fewer reuses to make them more environmentally friendly than single-use plastic bags, which means customers have to replace paper bags more frequently.Environmentalists, though, are not entirely convinced. They think that BP is stressing the problem of banning plastic for its own interest. “While it’s true that it takes less energy to produce and transport plastic than glass, a glass bottle can be reused dozens of times and is recyclable. Plus, materials like glass when they escape collection don’t go on polluting our oceans and rivers for hundreds of years," said Louise Edge, from Greenpeace UK.Steps to encourage recycling are being taken. The UK, for example, will introduce a new tax on the manufacture and import of plastic packaging in 2022. There are also lots of developments taking place with alternative materials. These may be the final defense against the unintended consequences of plastic bans.What is astonishing about BP' s annual report?

C. 　 BP has become one of the world' s biggest oil companies.

D. 　 Cutting back on plastic use may affect product quality.

45.In the race to the moon, who came in first?You might say the answer is Neil Armstrong, Buzz Aldrin, and Michael Collins, the crew of Apollo 11. Or you could represent for the crew of Apollo 10 , which reached the moon in May 1969 and then headed back to Earth without landing.But there is a much stranger answer to this question, depending on how much you care about humans and what your definition(定义)of reaching the moon might be. Before any people arrived at the moon, other animals had got there first. And unlike the dogs and monkeys that were made famous in early space shots and Earth orbits, the first creatures to reach the moon were a pair of tortoises , Discovery’s Amy Shira Teitel reminded us.The Soviet spacecraft (航天器) sent the animals around the moon—although not into its orbit—during a mission in the middle of September, 1968. The unmanned(无人驾驶的)craft then returned to Earth and dashed into the Indian Ocean, after which the Russians recovered the craft.A month later, Soviet scientists revealed that the spacecraft had been a tiny ship, carrying the tortoises, wine flies, meal worms, plants, seeds, bacteria, and other living matter.The tortoises, as history records, lost about 10 percent of their body weight, but had a healthy appetite when they returned to Earth. In the following checkups comparing the animals to “stay-at-home turtles used as a test control,” most things seemed normal, aside from some vaguely explained minor problems with the liver.What this all means is that, as Teitel explained, “The first living beings to see an Earthrise from the Moon were Russian tortoises. However, as far as I can tell, the animals were not named.”What happened to the Soviet spacecraft?

A. 　 It was wrecked during the mission.

B. 　 It was recovered after its return to Earth.

C. 　 It stayed in the moon’s orbit.

D. 　 It disappeared in the outer space.
