Vivian Maier was an American street photographer born in New York City. Although born in the U.S., it was in France that Maier 1 most of her youth. Maier returned to the U.S. in 1951 where she worked 2 a nanny for over 40 years. A nanny is a person who takes care of young children in the children's own home.
A nanny's job is not easy. In her free time,3Vivian begun to try the art of photography. She spent her days off walking along the4 of Chicago and taking photographs. Vivian would take photos that she5 from the eyes of others secretly. Most people did not know they were taken in the pictures. She took over 150,000 photographs during her lifetime6 of the people and buildings of Chicago, New York City, and Los Angeles, although she also travelled and photographed worldwide.
During her lifetime, Vivian's photographs were unknown and unpublished. Many of her photos were never printed because of 7. She never got married. She had no children either. She lived a 8 life and became even poorer in her old age.
A Chicago collector, John Maloof, happened to find some of Vivian's photos at the market. He decided to 9 Vivian's photographs on the website. Thousands of people showed their great 10 in them. Vivian's works have become famous around the world since then.
Vivian Maier opened one of the most attractive windows of American life in the second half of the twentieth century.

A company says it has completed the first 3D-printed home recently. The home was shown to reporters and visitors at a music festival.
The building company has developed large 3D- printers that build homes with mortar, a hard and strong material. It uses robotics, computer programs and advanced materials to make houses.
Jason Ballard is the company's chief engineer. "So I'm standing in front of the first 3D-printed home in America. This house was actually printed in high winds, blowing dust and rain." It is important for the printing programmes to operate in bad weather conditions, such as weather disasters. The goal is to print homes in developing countries. So the printer has to be light enough to move from one property to the next.
Ballard imagines that someday, many 3D-printers will operate around the world to make homes. "It's actually a lot more simple to build a printer than it is to build a house," he said. "We ran this printer at about a quarter speed to print this house, and completed it in about 48 hours of print time."
The company developed this technology not to make money but to help provide a quick, cheap housing solution for the millions of people who need it most. There are about a billion people that don't have one of life's most basic human needs, and that's safe shelter.
Ballard says his company already works on housing needs with poor families in different areas. But he says that to really make a difference, the program will need to be greatly improved. He added that since the 3D-printing process is so much faster than traditional homebuilding, a whole community could be built in just a few months. He believes over time, people can get the new home below $4,000 with the help of 3D-printers.
Science is proving what pet owners have long believed: Dogs understand what we're feeling. Especially, dogs can recognize(识别) the difference between a happy and an angry human face, a study published Thursday in Current Biology suggests.
It's the first research to show that dogs are sensitive (敏感) to our facial expressions, says the author Ludwig Huber at the University of Veterinary Medicine, Vienna.
In the Austrian study, 20 different kinds of pet dogs were taught to play a computer game through a series of exercises. In the first step, the dogs were shown two touch screens, one with a circle and one with a square. Through the exercises, they learned that a treat would appear if they chose the right one.
Eleven of the 20 dogs were able to catch on to rules of the game and make it to the next test, where they were shown photos of happy and angry faces. The dogs were rewarded if they picked certain expression correctly. During the test, the dogs were shown only the upper half or the lower half of a face.
It was easier to teach the dogs to choose a happy expression than an angry one, suggesting the dogs do indeed understand the meaning behind the expression, Huber says.
As a test, the dogs were then presented with: the same half of the faces they saw during the training, but from different people， the other half of the faces used in training， the other half of new faces， the left half of the faces used in training.
In the cases, the dogs chose the right answer 70 to 100 percent of the time.
Dogs who had been trained to recognize an expression of anger or happiness on the upper part of a face could find the same expression when shown only the lower part. Huber says, "The only possible explanation is that they recall from memory of everyday life how a whole human face looks when happy or angry."
Dog owners know their pets not only recognize emotions but also understand the feelings.
①the other half of some new faces
②the right half of the faces used in training
③the other half of the faces used in training
④the same half of the faces they saw but from different people

(Wendy and Daniel are chatting in the playground after lunch.)
Wendy: Hi, Daniel. How was your trip to Hongshan Forest Zoo?
Daniel: Wonderful! There are animals in the zoo.
Wendy: Have you seen the pandas? They are the most popular animals in the zoo. Daniel: Yes. Pandas are cute. Every year, lots ofcome to see them. Wendy: The newspaper says the zoo has two lovely koalas. Did you take photos with them?
Daniel: No, koalas are shy animals. The zoo keeper told us cameras might make them get easily.
Wendy: Why are there so few koalas in China? Are they difficult to keep? Daniel: Yes. Theya special kind of tree leaves. This kind of trees are hard to grow in Nanjing.
Wendy: Really? I simply can't to visit them in the zoo. Daniel: Remember not to take photos of them.
Wendy: OK, I will.
The population of Earth is still going up. There will be less and less good land for growing crops in the future. People worry that there will not be enough food for everyone in the middle of this century.
Recently scientists have discovered one strange plant named fedtschenkoi（玉吊钟）may help. It can absorb（吸收）carbon dioxide(CO₂) at night. It only needs 10 times less water than food plants like beans. This means it can grow in the desert(沙漠).
In which ways could this plant help us?
Since deserts are increasing in size because of the changes in Earth's climate, growing plants there will be more and more important. Although it is dangerous to eat this plant, scientists can still study something about it: how it absorbs CO₂ at night while many other plants only do this during the day, and why it is suited to the desert.
There is another direction to take the research in. Producing a desert plant to eat will be difficult, but there is still possibility to use the genes(基因)from this plant and put them into food plants.
The other way is to grow this type of plant for fuel(燃料). At the moment we grow plants for fuel in good land. If we do it in deserts instead, more good land can be used to grow plants for food.
Desert plants have special qualities, which could be an answer to our future food or energy needs. Scientists are working hard on it.
The Desert Plant Could Help | |
The problems of the future | ◆The population on Earth is becoming than before. ◆There is less and lessland for growing crops. ◆There will not be enough food in the future, which makes people |
The discovery of the scientists | ◆It is an plant named fedtschenkoi. ◆Food plants like beans need 10 times water than it does in deserts. |
The ways it could us | ◆The scientists are studying how it absorbs CO₂ and why it isfor living in desert. ◆It is to use genes from one plant and then put it inside another. ◆It will be better if we can grow plants for fuel in deserts than in good land. |
Conclusion | ◆Because desert plants have special qualities, it mayour food and energy problems in the future. |
Nowadays, studying abroad is becoming more and more popular in China. Many parents send their children abroad instead of letting them receive e at home.
There are many advantages for people to attend school abroad. Firstly, he can use the foreign language in his everyday life so that his ability in the second language may be greatly i. While studying in a foreign country, he will meet many students from abroad and it is much easier to make f with them. Also, he can get familiar with the latest knowledge in different fields. In this wthere is every chance that he is ato widen his horizon (眼界) and broaden his mind.
Of course, attending schools abroad may ba lot of problems. The most serious one is language barrier(障碍). Most of the students who go abroad don't have e skills in the language spoken there. As a result, on arriving there, they will find it difficult to uwhat the teachers say. Moreover, they don't know the customs(风俗) of local people very wand they may have trouble dealing with some situations.
Therefore, one must think of both sides carefully before m a decision. The place where you study is not very important, but the desire(渴望) to learn matters the most.
