Can you imagine wear a pretty sweater made from garbages? It could happen! A few companies across the country are making clothes from things that are being thrown away by people. For example, company makes sweaters of old plastic bottles. First, the bottles are cut into small pieces. The pieces are melted. Then the melting plastic is made into long and thin threads. The threads are used to make sweaters which feels very soft and light.

Believe it or not, these sweaters sell good in spite of the fact which they are not cheap at all. Many people thought that these recycled clothes can help us cut down on garbage.

If you could be anybody in the world, who would it be? Your neighbour or a super star? A few people have experienced what it might be like to step into the skin of another person, thanks to an unusual virtual reality(虚拟现实)device. Rikke Wahl, an actress, model and artist, was one of the participants in a body swapping experiment at the Be Another lab, a project developed by a group of artists based in Barcelona. She swapped with her partner, an actor, using a machine called The Machine to Be Another and temporarily became a man. "As I looked down, I saw my whole body as a man, dressed in my partner's pants," she said. "That's the picture I remember best."
The set-up is relatively simple. Both users wear a virtual reality headset with a camera on the top. The video from each camera is sent to the other person, so what you see is the exact view of your partner. If she moves her arm, you see it. If you move your arm, she sees it.
To get used to seeing another person's body without actually having control of it, participants start by raising their arms and legs very slowly, so that the other can follow along. Eventually, this kind of slow synchronised(同步的)movement becomes comfortable, and participants really start to feel as though they are living in another person's body.
Using such technology promises to alter people's behaviour afterwards-potentially for the better. Studies have shown that virtual reality can be effective in fighting racism-the bias(偏见)that humans have against those who don't look or sound like them. Researchers at the University of Barcelona gave people a questionnaire called the Implicit Association Test, which measures the strength of people's associations between, for instance, black people and adjectives such as good, bad, athletic or awkward. Then they asked them to control the body of a dark skinned digital character using virtual reality glasses, before taking the test again. This time, the participants' bias scores were lower. The idea is that once you've "put yourself in another's shoes" you're less likely to think ill of them, because your brain has internalised the feeling of being that person.
The creators of The Machine to Be Another hope to achieve a similar result. "At the end of body swapping, people feel like holding each other in their arms," says Arthur Pointeau, a programmer with the project. "It's a really nice way to have this kind of experience. I would really, really recommend it to everyone."

   Leon,12,was born without fingers on his left hand. That didn't stop him from being able to do many tasks. But Leon could not grasp more than one object at a time. So Leon's father,Paul,created a prosthesis(义肢),using a3-D printer. Now Leon has fingers that can open and close. "It was a do-it-yourself,father and son adventure," says Paul.

When Leon was a baby,his doctor advised his parents not to give him a prosthetic hand until he was in his early teens. "The doctor said Leon should first learn to get full use of the hand he was born with,"says Paul. As Leon got older,his father considered buying a prosthetic hand,which can cost as much as $30,000. Then Paul found a more affordable solution.

One day,Paul discovered a video on the Internet about Robohand,a prosthesis created by a 3--D printer. He downloaded the free instructions and called Robohand's creators for advice. They told him all he needed was a 3-D printer-which costs around $2,000 and some materials.

Luckily,Leon's school had recently bought a 3-D printer and it offered to help Paul build the hand for Leon. "We used a soccer shin pad(护胫),cardboard,and tape. They cost about $10,"says Paul.

With his new hand,Leon can do things better. "I can help my mom more,because now I can carry two grocery bags,"he says.

Leon's father has already built several hands for Leon. Leon helps design each one. He says there's one thing in particular that he wants to do with a future prosthesis. "The goal,"he tells the reporter from the local evening paper,"is to be able to tie my shoelaces(鞋带)".

【小题1】Why did Leon's doctor disapprove of his using a prosthesis in his childhood?
A.The prosthetic technology was underdeveloped then.
B.A prosthesis was very expensive at that time.
C.To learn to use the disabled hand was important.
D.The original hand could do many tasks.
【小题2】Leon's father managed to get Leon a new hand by _________.
A.collecting money on the Internet
B.buying a prosthetic hand
C.buying a 3-D printer
D.printing a hand
【小题3】The materials used for Leon's hand can be described as _______.
A.cheap and common
B.strange and valuable
C.personal and lovely
D.basic and solid
【小题4】What is the best title for the passage?
A.A DIY EnthusiastB.A Helping Hand
C.A Great AdventureD.A Lucky Escape

   Nature has its own way of balancing itself out,but when we humans get involved,we tend to throw things out of control. Forests and oceans are natural carbon sinks that absorb carbon dioxide from the atmosphere, but since we’ve been pumping too much into the air, those sinks can’t keep up. Scientists at the Max Planck Institute for the Advancement of Science in Germany, led by biologist Tobias Erb,have figured out a way to supercharge plants to make them better at absorbing carbon dioxide, which could be a key defense against climate change.

Erb and his team figured out a way to make plants more efficient(效率高的)at absorbing carbon, so that they consumed more carbon in a shorter amount of time. “If you think about plants, they are efficient carbon dioxide -fixing filters, but they are not fast,” Erb said. “I think there is a chance to improve existing biology with synthetic(人造的)biology.”

Erb’s team identified 17 enzymes(酶)from nine different organisms, re-engineering three of them, which had enlarged carbon consumption. When those enzymes worked together as a team, they worked better at not only plants’ natural enzymes, but also themselves individually.

Existing enzymes in plants consume about 5 to 10 molecules(分子)of carbon dioxide per second. The team of enzymes that Erb used consumed 80 molecules per second.

So far, these enzymes have only been tested in test tubes in the lab, but the next step is real world testing where the enzymes would be introduced into plants to see if the same result occurs. If those tests show that plants really can be supercharged, we will have a new tool in the fight against climate change where not only do we protect the amazing carbon-absorbing forests we have, but we also apply these super plants or an artificial leaf technology using the enzymes into other fields.

【小题1】Why can't forests and oceans balance nature nowadays?
A.Oceans and forests are getting smaller.
B.We human beings give off too much carbon dioxide.
C.A large number of forests are cut down.
D.There are too many creatures in the world.
【小题2】Which is the key defense against climate change according to Erb and his team?
A.To increase the plants' ability and efficiency to absorb carbon dioxide.
B.To make oceans and forests absorb more carbon dioxide quickly.
C.To reduce humans' activities giving off too much carbon dioxide.
D.To increase the number of plants in the world.
【小题3】What can we conclude from the last paragraph?
A.The enzymes have proved useful in the real world.
B.Erb’s team are confident about the technology.
C.The enzymes only work in the lab.
D.The technology may have a bright future.
【小题4】This passage is intended to ____.
A.introduce a possible way to better plants’ ability to absorb carbon dioxide
B.call on people to pay more attention to the balance of nature
C.analyze the cause and result of climate change related to plants
D.explore the possibility of using plants to fight against climate change

   According to a study published last week in the journal Science,scientists have found a way to change a plant's genes(基因)in order to make it use sunlight more quickly. Someday,the results could increase the amount of food produced around the world.

By changing a plant's genes,the scientists were able to increase leaf growth on plants by 14-20 percent. Specifically,scientists changed the plant's protective(保护的)system. “Normally,this system is activated when a plant gets too much sunlight,”said scientist Krishna Niyogi,co-author of the study. “When the plant senses the light,it gets rid of extra energy and creates more leaves. When the plant is in the shade,the protective system is turned off. But the process is slow.”

Stephen Long is the lead author of the study. He compared a plant's protective system to light-adjusting glasses.“When a person wears the glasses outside during the day,the lenses(镜片)darken and lighten depending on how sunny it is. Plants do the same thing,”he said.“But in plants the adjustment can take anywhere from 10 minutes to an hour. This makes it hard for plants to get the right amount of sunlight needed to create food.”

The new study sped up the process. By changing the plant's genes,it's more quickly than normal to turn on and turn off the protective system. As a result,leaf growth on the plants scientists used in the study increased. Leaf growth on two plants increased by 20 percent, while leaf growth on a third plant increased by 14percent. Scientists conducted the study on tobacco plants. But they thought the genetic modification would produce the same results in corn or rice.

【小题1】What does the plant's protective system need to keep activated?
A.Mild shade.B.Leaf growth.
C.Genetic changes.D.Enough sunlight.
【小题2】What does the underlined word“modification”in Paragraph 4mean?
A.Development.B.Decoration.
C.Change.D.Copying.
【小题3】What can we infer from this text?
A.Changing how a plant uses sunlight could mean more food in the future.
B.When the plant is in the shade, its protective system is turned off slowly.
C.Too much sunlight will damage plants' protective system.
D.It is hard for plants to create food without enough sunlight.
