A new “smart bin” could spell the end of environment - conscious families spending hours sorting tins, cartons, bottles, and cardboard for recycling. The invention, which automatically sorts rubbish into recycling categories, is being trialed in Poland and is set to go on sale in the UK within a few years.

The bin, designed by start - up company Bin. E, recognizes different types of waste via a system positioned inside the bin which uses sensors, image recognition and artificial intelligence. Once waste is placed inside, the camera and sensors identify its type and place it in one of the smaller bins. Then it compresses (压缩) the waste so it occupies less space.

News of the launch showed that more than a million households are being forced to accept bin collections every three or four weeks, because councils are trying to force them to recycle more. Data collected by The Telegraph has showed at least 18 areas have moved or will shortly be moving to three - weekly rubbish collections, while a further three have adopted or are trialing four - weekly collections. While reducing general bin collections, councils are increasing the frequency of recycling collections in a bid to change people’s behaviour. It is thought that the bin could be stocked by department stores such as John Lewis, which said it is introducing new hi - tech recycling bins to satisfy increasing customer appetite for them. Matt Thomas, a utility (家用设施) seller at John Lewis, said, “We’ve recently seen a jump in specialist bins sales, with a 25 percent increase in the last few months alone. We have noticed our customers are becoming more and more sustainability focused, choosing dual compartment (双格) recycling bins that make it far easier to recycle different types of waste. In response to this demand, we are really excited to introduce a new voice and sensor activated smart bin this autumn / winter season — designed to use new technology to make recycling more efficient and functional for the everyday home.”

1.What can we know about the smart bin?

A. It has entered the UK market.

B. It breaks up the garbage quickly.

C. It can classify different kinds of rubbish.

D. It expands its space with the increase of garbage.

2.What does the underlined sentence in the last paragraph mean?

A. The cost of producing the bins has raised.

B. The smart bins have been the best sellers.

C. The stores have sold out the new bins in a very short time.

D. The sales volume of the recycling bins has increased suddenly.

3.What can we infer from Matt Thomas, words?

A. People can get the smart bins at a low price.

B. People always spend much time in rubbish collections.

C. More and more hi - tech bins are designed for customers.

D. People pay more attention to environmental protection than before.

4.Which of the following tan be the best title for the text?

The UN Environment Programme says that rising temperature could mean the end for some

migrating animals.Migrating or mobile animals move through several environments as they travel away from the cold of winter to warmer areas. Birds may fly from one part of the world to another, perhaps stopping at feeding grounds(聚食场) on the way. Whales and turtles cover vast areas of ocean. The report says that changes in any one of the places which these animals use can cause serious harm."Obviously these animals have developed their traveling patterns over thousands of years. But climate change is almost certain to be extreme over the next 25 t0 50 years, and it is extremely

unlikely that these animals can change their habits fast enough," said the report author Dr. Robert Hepworth.

Hardest hit by rising temperatures are turtles. Scientists have found that at higher temperatures,turtles produce far more female eggs than male ones. In parts of Malaysia, turtle birthing sites are producing only females, the report says, It also provides evidence that some turtles are more likely to develop cancer as the waters get warmer.

With birds, the main problem is climate-related damage to important areas at either end of the travels or at resting places along the way. About one-fifth of migrating birds are now in danger because of climate-related changes including rising sea levels, land loss and more violent storms,the report concludes.Other animals picked out as particularly in danger include:

◆the North Atlantic Right Whale, whose main food( tiny shrimp ) is disturbed by the change in ocean flows

◆the White-beaked Dolphin, which is out-competed by other kinds of dolphins in warmer waters.

The report is not all bad news. Even with major climatic changes, protecting the environment can still help mobile animals to recover.

"We need governments to start taking action at the national and international level. The clock is running." said Dr Hepworth. And some animals are already adapting, with the report mentioning whales that are changing their feeding behavior, finding new feeding grounds and new foods to eat.

48. What does the text mainly talk about?

A. The effect of climate change on migrating animals,

B. How animals are adapting to changes in temperature.

C. The importance of saving migrating animals.

D. The need for government policies to prevent global warming.

49. Which of the following is mentioned as a consequence of rising temperatures?

A. More storms will affect the ability of whales to find their feeding grounds.

B. 20% of all birds are likely to die out because of land loss.

C. Migrating animals can adapt to the changes quickly.

D. Warmer oceans will increase the competition between different kinds of dolphins.

Weather could power the next generation of smart windows. Researchers have created glass by harvesting energy from wind and precipitation(降水).The approach offers an alternative to other smart windows powered by batteries, solar panels, and even standard power outlets. “The creation represents a new kind of renewable energy source”, says Liming Dai, a nanomaterial engineer at Case Western Reserve University in Cleveland, Ohio, who was not involved in the research.

Smart glass, which changes its characteristics to block out light or heat, has been around for decades. Common examples include glare-fighting rearview(后视) car mirrors and windows that change color for energy savings and privacy. But many are expensive, and people are still looking for eco-friendly ways to power the windows. Batteries and plug-in outlets aren’t apparently “green”, and built-in solar panels can cloud or hide parts of the glass.

In experiments, the glass produced up to 130 milliwatts per square meter, enough to power a pacemaker or a smart phone while it’s asleep, the team reported online last month in ACS Nano. This output might suit many applications, such as being a power source for home or office electronics, says co-developer and scientist Zhong Wang of the Georgia Institute of Technology in Atlanta Since their first project in 2012, a light-up sidewalk powered by footsteps, he and his colleagues have miniaturized their generators to create everything from self-cleaning keyboards to sensors for security systems.

But Wang and colleagues still have more work to do before this smart glass is ready for commercialization. Now, the glass has no way to store the energy it creates. To solve this problem, Dai says, transparent supercapacitors(超级电容器) could be placed into the glass without decreasing visibility.

For now, the team wants to improve the energy efficiency of their nanogenerators. These tiny power plants can convert about 60% of the mechanical energy that they encounter into electricity. “The output power is a constant goal,” Wang says. “Free energy surrounds us, and anything can happen if you take control of it."

1.What is unique about the smart glass?

A.It can protect privacy. B.It is more expensive.

C.It is powered by weather. D.It can block out light and heat.

2.What is the main idea of paragraph 3?

A.The research history of Zhong Wang.

B.The experimental process of Zhong Wang.

C.The research theory of Zhong Wang’s team.

D.The experimental findings of Zhong Wang's team.

3.What is the drawback of the smart glass?

A.It cannot suit the supercapacitors. B.It cannot keep its produced electricity.

C.It cannot power a smart phone. D.It cannot change its color according to weather.

4.Which of the following best explains “convert” underlined in the last paragraph?

A.Transform. B.Consume.

C.Waste. D.Reserve.

According to the findings of a new study, telling kids they’re smart enhances the idea that intelligence is a genetic gift rather than a skill that ran he improved, and children who think their intelligence is fixer! are not likely to pay attention to mistakes and recover from them.

In the study publisher! online, researchers looked at 123 children who were about 7. The team assessed the children to determine whether they had a “growth mindset（思维定式）”. They asked the children to complete a fast-paced computer task while their brain activities were recorded. During the recording, researchers noted that brain activity stopped within a half-second after making a mistake. The larger the brain response was, the more the child focused on the error.

Based on the data they collected, the researchers concluded that children with a “growth mindset” were much more likely to have a larger brain response after making a mistake, and in turn were more likely to improve their performance by paying closer attention to the task after making an error.

For parents, the lessons are clear: for starters, don’t pay praises that suggest intelligence is fixed. If a child hands you an A test, don’t say “You are smart!” Instead say “Wow, that study really paid off!”

Second, focus on using errors to work together and learn. Many parents and teachers shy away from mentioning a child’s mistakes, telling them “It’s OK. You’ll get it next time.” without giving them the opportunity to figure out what went wrong. Instead, it’s better to tell the child that mistakes happen, and to pay attention and work to figure out where and how they made the mistake.

1.What’s the resold of telling kids they’re clever?

A. They may think efforts are useful.

B. They may be attentive to their mistakes.

C. They may think they’re very clever.

D. They may think intelligence is fixed at birth.

2.How would children with a “growth mindset” react to their mistakes in the study?

A. They would be more careful to their mistakes and more likely to improve.

B. They had a smaller response and would pay no attention to their errors.

C. They would he less attentive to their errors and pay little attention to their mistakes.

D. They are more likely to have a larger brain response before making a mistake.

3.What does the author advise the parents to do when their kids make mistakes?

A. Comfort the kids and stress the efforts they made.

B. Tell them it’s OK and they will get it next time.

C. Praise the progress they made but not their smartness.

D. Let the child think about what mistakes they made.
