Peng Liyiian, First Lady of China, made a speech in English at the United Nations on September 26, 2015. She talked about education and shared her Chinese dream with the world.

    Peng began her speech with a story of her father. Her father grew up in a small village in China. In those days, not many villagers could read, so her father opened a night school to teach them. With his help, many people learned to write their names and read newspapers for the first time. And many women were able to teach their children how to read. Peng's father's love for education influenced her deeply. She was lucky enough to have a good education. Later, she followed her father's footsteps and became a professor of music.

    Education is important, but still, some children in China can't go to school. Peng hopes that all children can have a good education, and that is her Chinese dream.

    Have you ever tried to hide your emotions (情感)from someone during a conversation? {#blank#}1{#/blank#}

    Scientists from the Ohio State University have found that people are able to tell other people's emotions according to changes in the color of their faces.

    Scientists studied pictures of people's facial expressions. {#blank#}2{#/blank#} For example, happiness makes our faces red around the cheeks and a little blue around the chin. Disgust(厌恶)creates not only a blue-yellow color around the lips, but also a red- green color around the nose and forehead.

    “We believe these color patterns are the result of small changes in blood flow triggered(触发) by the central nervous(神经) system." Lead researcher Alex Martinez said.

    {#blank#}3{#/blank#} Does the color alone or also facial expressions help people tell other's emotions?

    To figure this out, scientists added color patterns to pictures of faces that showed no facial expressions. {#blank#}4{#/blank#}They were able to tell the emotions 75 percent of the timewithout any difficulty.{#blank#}5{#/blank#} For example, when two people are heatedly arguing over something, we say they are red in the face. When a person is very angry, we'd say he or she is blue in the face.

    People burn coal, gas and oil to get energy But there are problems with these fuels (燃料). (A)________, these fuels cause pollution. Pollution makes the air and water unsafe for humans. Secondly, these fuels will not last forever. One day, we will run out of these fuels.

    Scientists are looking for new kinds of energy. One is heat from the Earth. We know that (B)地球中央非常热. We cannot reach the center of the Earth, but in some places the heat from the Earth's center comes to the surface of the Earth. Perhaps you know about some of these places One place is volcanoes (火山). It is very dangerous to go near an active volcano, (C) _______ we cannot use the energy from this.

    Another kind of heat from the Earth is hot springs (温泉). In these places, hot water comes to the surface of the Earth. If this water is near a town, the hot water can be sent in pipes (管道) directly to people's houses to heat them .In Iceland, this is a common way to heat houses.

    (D)In Australia, scientists are looking for ways to make energy using hot rocks under the surface of the Earth. They want to pump (抽水)water onto the hot rocks .When the water hits the rocks, it makes stream(蒸汽). The steam is piped to power stations where (E) it is used to make electricity. The electricity can then be sent all over the country.

    Halloween is a strange holiday. It started several centuries ago in Europe. It began as "Hallow Evening" which means "holy night". At that time November 1st was called "All Saints' Day" (万圣日) and people honored all the saints who did not have their own special day. People believed that all the spirits of dead people were active on the night of October 31st. So people would play all sorts of tricks on each other.

    Black is one of the traditional Halloween colors, probably because Halloween festivals and traditions took place at night. Pumpkins area symbol of Halloween, so orange has become the other traditional Halloween color. Making lanterns out of pumpkins is a Halloween custom.

    Halloween is great fun for children. They dress up as ghosts(鬼) or witches(女巫). Small children go "Trick-or-Treat". They wear costumes, knock on doors, and shout, "Trick or Treat!" People almost always choose to give them candy as a treat, instead of choosing to receive a trick from the children. Adults sometimes "trick or treat" their friends, too. Usually the "treat" is a glass of wine or some small gifts.
