The science of papermaking addresses the methods, equipment, and materials used to make paper and cardboard, these being used widely for printing, writing, and packaging, among many other purposes and useful products. Today almost all paper is produced using industrial machinery. 1.
The method of manual（手工的）papermaking changed very little over time, despite advances in technologies.2.Separate the useful fibre from the rest of raw materials. Beat down the fibre into pulp（纸浆）.Adjust the color, chemical, biological, and other properties of the paper. Screen （筛选）the resulting liquid. Press and dry to get the actual paper.
3. It is made of stainless materials and set in a wooden frame similar to that of a window. Then completely bathe it in the liquid and draw it out. Water is removed and the wet mat of fibre is laid on top of a damp cloth. The fairly damp fiber is then dried. Finally, the paper is then cut to the desired shape and packed.
The wooden frame is called a “deckle” （定纸框）. 4. The “deckle edges” are one of the indications that the paper was made by hand. Deckle-edged paper is occasionally imitated today to create the impression of old-fashioned luxury.
5. It is also used in paper factories to check the quality of the production process. The “handsheets" made according to TAPPI Standard T205 are tested for paper characteristics such as brightness, strength and degree of sizing.
A.Screening the fibre involves using a special net.
B.The process of papermaking is really complicated.
C.It leaves the edges of the paper slightly irregular and wavy.
D.In laboratories handmade paper is prepared to study papermaking.
E.However, traditional papermaking in Asia uses the inner skin fibres of plants.
F.The process of manufacturing handmade paper can be generalized into five steps.
G.But handmade paper is still appreciated for its distinctive uniqueness and the skilled craft.
Scientists have discovered why the Mona Lisa's expression looks so different to different people and at different times.
For centuries, art lovers and critics have been confused by and debated the Leonardo Da Vinci painting's gaze and slight smile.
But new research from the University of California, San Francisco has shed new light on the shining and seemingly changing face of the Mona Lisa.
Through experiments, they discovered that our emotions really do change how we see a neutral face.
Dr Erika Siegel and her colleagues study how our emotions change our perceptions of the world around us—even when we aren't aware that something has changed our feelings.
This relies on the modern theory of" the brain as a predictive organ, instead of a reactive one,” says Dr Siegel.
In other words, “we have a lifetime of experience and we use those experiences to predict what we are going to experience next.”
We all have one dominant eye and one more passive non-dominant one. If each eye is receiving different information, we only consciously perceive what dominant one sees. But non-dominant sights can still enter our subconscious.
They showed 43 people two sets of flashing images simultaneously, so that the dominant eye saw and registered neutral expressions, while the non-dominant eye “saw” flashes of neutral, or smiling faces, which they would only subconsciously be aware of.
After viewing the flashing faces, the researchers showed the participants options of faces and asked them to pick out which ones they had seen.
When their non-dominant eyes had seen a happy face, they were more likely to think the neutral face had actually been smiling, and the same was true for other expressions.
This means that “if you see the Mona Lisa after you have just had a screaming fight with your husband, you're going to see the painting differently,” says Dr Siegel.
“But if you're having the time of your life at the Louvre, you're going to see the mysterious smile,” she adds.
“We are the architects of our own experience. Our brain makes predictions about what it expects to see and uses information from the world to update its expectations,”Dr Siegel says.
1.What is the purpose of Dr Siegel's research?

Most heroes are not super. They don’t appear in comic books, on television, or in movies. They just do what they believe needs to be done to make their world a better place. Bike Batman is one of them.
Bike Batman is a 30-year-old married engineer who lives in Seattle, Washington. He’s a cyclist who also buys and sells bikes as a hobby.
About three years ago, he was looking for a bike for his wife. He found one on Craigslist, a website where people list things they want to sell. As he often does, he also looked at Bike Index, a popular website that allows users to register their bikes and post reports when they’re taken. The bike, which he was considering purchasing, clearly matched one reported stolen on Bike Index. Then he called the person who claimed to be the bike’s owner and arranged to meet him— supposedly to complete the sale. When the two men met, Bike Batman told the thief, “You’ve got two options. You can wait until a police officer gets here, or you can just get out of here.” You can imagine what the thief did.
After that first success, Bike Batman developed a safer routine. When he sees questionable bike ads on Craigslist, he cross-references the image with bikes reported on Bike Index. Once he has confirmed it with the owner, he arranges a meet-up with the thief and will call the Seattle police department so that officers can participate in the action. In more than half of the 22 cases in which he has got back and returned bikes, the thieves have been arrested. In one case, Bike Batman even helped a family recover a wide range of prized possessions that suspects had stolen during a home burglary.
His nickname came from a discussion with a police officer who suggested he be called “Robin Hood”. Since he wasn’t exactly stealing from the rich and giving to the poor, “Batman” seemed a better fit. The idea of a superhero punishing criminals feels pretty silly to him, but the main reason he continues his work is to keep up Seattle’s reputation as a friendly city.

3.Why does Bike Batman help find the lost bikes?

Where should an adventurous tourist go? After you've done sightseeing in London, shopping in New York, enjoyed the local food in Paris, and danced to your heart's content at the Brazilian carnival, where else can you go? What attractive tourist destination awaits you?
Well, Antarctica sounds like the holiday of a lifetime! It's considered the last great wilderness on Earth. Just a few scientists in research stations share the icy landscape with penguins and other animals which can struggle with the low temperatures.
Tourism began in Antarctica in the 1950s and it's still small part. About 37,000 tourists are expected there this season, but many won't even leave the boat.
The BBC’s Juliet Rix visited the frozen continent and asked herself if she should be there at all, causing potential problems to such a sensitive environment. Her tour guide admitted that all visitors leave a footprint and they all go to the same places, the accessible coastline, which is also where the penguins and seals go to raise.
But some people believe that if carefully controlled, tourism can be good for Antarctica. It has no native population and it needs advocates. Visitors to the icy continent might be ready to support and even to fund its preservation. And they're likely to engage in the discussion about global warming, which has led to the melting of glaciers.
According to Rix, guidelines are followed when you're about to set foot in Antarctica and tourists have to disinfect their boots to make sure no alien species are introduced.
And once on land, there's no eating or smoking. Rocks, bone fragments—nothing should be taken as a souvenir and nothing should be left behind.
Tourists fortunate enough to visit the Antarctic must be aware that this is not their home and keep their fingers crossed that future generations will also be able to enjoy such breathtaking views.
1.What can we infer from the second paragraph?
A.The Antarctic has become the best place for people to travel.
B.Only scientists can be allowed to go to Antarctic.
C.Antarctic is less affected by human activities.
D.No animals can survive in Antarctic expect penguins.
2.Juliet Rix’s travel in Antarctic mentioned in the fourth paragraph indicates that .
A.whether tourists should go to Antarctic or not should be considered carefully
B.governments should take measures to stop tourists from going to Antarctic
C.the animals’ habitat in Antarctic has been seriously affected by tourism
D.only journalists begin to pay attention to the environmental protection in Antarctic
3.What does the underlined word “disinfect” in the sixth paragraph probably mean?
A.Clean. B.Move.
C.Remove. D.Change.
