Article: We already know the fastest,least expensive way to slow down climate change:use less energy.With a little effort,and not much money,most of us could reduce our energy diets by 25 percent or more--doing the Earth a favor while also helping our wallets. Not long ago,my wife,PJ,and I tried a new diet--not to lose a little weight but to answer an annoying question about climate change.Scientists have reported recently that the world is heating up even faster than predicted only a few years ago,and that the consequences could be severe if we don't keep reducing emission of carbon dioxide(CO2)and other greenhouse gases that are trapping heat in our atmosphere. We decided to try an experiment.For one month we recorded our personal emission of CO2.We wanted to see how much we could cut back,so we went on a strict diet.The average US household produces about 150 pounds of CO2a day by doing common things like turning on air conditioning or driving cars.That's more than twice the European average and almost five times the global average,mostly because Americans drive more and have bigger houses.But how much should we try to reduce? For an answer,I checked with Tim Flannery,author of The Weather Makers:How Man Is Changing the Climate and What It Means for Life on Earth.In his book,he had challenged readers to make deep cuts in personal emission to keep the world from reaching extremely important _ ,such as the melting of the ice sheets in Greenland or West Antarctica."To stay below that point,we need to reduce CO2emission by 80 percent,"he said. Good advice,I thought.I'd opened our bedroom windows to let in the wind.We'd gotten so used to keeping our air-conditioning going around the clock.I'd almost forgotten the windows even opened.We should not let this happen again.It's time for us to change our habits if necessary. Question: Why did the author and his wife try a new diet? Options: A: To take special kinds of food. B: To respond to climate change. C: To lose weight. D: To improve their health.

Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze starts to lose its focus - until a third, with three black spots, is presented. Her gaze returns; she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world? Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects(a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise when the researchers started with drumbeats and moved to spots. Question: Babies are sensitive to the change in _ . Options: A: the size of cards. B: the colour of pictures. C: the shape of patterns. D: the number of objects.

Monet was particularly interested in the effect of light and would paint the same scene in different lighting conditions or times of the day. For example, he painted around 20 versions of the Rouen Cathedral from dawn to dusk. His most famous paintings include his Water lilies series. The paintings of Paul Cezanne had a lot of influence in the development of 20th century art, including Cubism and Fauvism . Cezanne is one of the most famous French artists and is known as a "post-impressionist", which was similar in some ways to impressionism but also broke away from some of its limitations. Famous French paintings include his Bathers and Mont St Victoire series. Henri Matisse was one of the most important famous French artists of the 20th century. He was considered one of the leaders of the Fauvist movement. He had a long and varied artistic career, painting in different styles ranging from Impressionism to Abstract. In 1941, Matisse was diagnosed with cancer and was forced into a wheelchair. But this didn't stop him completing the amazing Chapel of the Rosary in Vence. Degas is probably one of the most fascinating of all the famous French artists. He is known as one of the founders of Impressionism, but his paintings were also influenced by classicism, romanticism, and realism. His style is definitely very unique. He was a prolific artist, producing over one thousand works. He is best known for his paintings of ballet dancers. Question: During Henri Matisse's long artistic career, he _ . Options: A: painted paintings of different styles B: did his most famous paintings after 1941 C: painted in the style of Fauvism most frequently D: spent most of his time painting in a wheelchair

It helps a preschooler : Develop social skills As children play pretend, they explore relationships between family members, friends and coworkers and learn more about how people interact. Playing doctor, they imagine how physicians care for their patients. Playing house, they learn more about how parents feel about their children. Imaginative play helps develop empathy for others. If children can imagine how it feels to be left out of a game or to lose a pet, they are better able to help those in need. They become more willing to play fair, to share, and to cooperate. Build selfconfidence Young children have very little control over their lives. Imagining oneself as a builder of skyscrapers or a superhero defending the planet is empowering to a child. It helps them develop confidence in their abilities and their potential. Boost intellectual growth Using the imagination is the beginning of abstract thought.Children who can see a king's castle in a mound of sand or a delicious dinner in a mud pie are learning to think symbolically . This skill is important in school where a child will have to learn that numerals symbolize groups of objects, letters symbolize sounds, and so on. Practice language skills Kids who play pretend with their friends do a lot of talking.This helps _ their vocabulary, improve sentence structure and promote communication skills. Work out fears Playing pretend can help children work out their fears and worries. When children roleplay about the big, bad monster under the bed, they gain a sense of control over him and he doesn't seem quite so big or so bad. Imaginative play also helps kids vent confusing feelings they might have, such as anger toward a parent or compete with a new sibling . To encourage your youngster's imagination, read to him every day. Books offer children the opportunity to visit other worlds and create new ones of their own. For generations children have enjoyed reading the story... Question: What's NOT the advantage of children having a good imagination? Options: A: Understanding the other people's feelings and problems. B: Expressing their feelings like anger. C: Having a strong faith in their own abilities and potential. D: Helping them form a good habit of reading stories.
