HUNGER Hunger has become a serious problem in many parts of the world. The first cause of hunger is the fast growth of population. The Earth is no longer able to feed its more than seven billion people. There is not enough land for growing food. The change of climate also brings to the Earth more weather-related disasters such as storms and droughts … They heavily destroy crops. Wars are still happening. People are fighting, or running away from home. There's nobody to work on the field or in the factory to produce food. Technology is working hard to help solve part of this problem. In the future, we will have warning systems to reduce the loss from natural disasters. Low-cost means of transport will also be used to carry food to area-in-need.

Help me,40 điểm đấy. Đọc bài đọc và tả lời câu hỏi BENJAMIN FRANKLIN Few people can embody the spirit of early America as much as Benjamin Franklin. He lived through almost the whole of the eighteenth century, being born six years after, and dying ten years before it ended. In this time he saw the American colonies grow from tiny settlements into a nation, and he also contributed much to the development of the new state. At the age of 17 Franklin ran away to Philadelphia. He had already received some training as a printer’s apprentice, and this helped him seven years later, with his first publication, the Pennsylvania Gazette. He also received a contract to do government printing work, which helped him to rise from his poor background to become a successful entrepreneur. Some of his experience in business was shared in his famous Poor Richard’s Almanak. which established his reputation throughout the American colonies. In another of his works, the Autobiography, which was written toward the end of his life, he shows the same quiet common sense. He was deeply interested in science and natural history, and his experiments with electricity and lightning led directly to the invention of the lightning rod. He was also interested in improving the conditions of his fellow men. He was involved in a number of projects in his native Philadelphia, including the setting up of a library, a university, a philosophical society, and-because he was a pragmatic man-a fire prevention service. In 1753 he became Postmaster-General of the colonies. Through this experience he began to develop the idea that the colonies of North America should be a single nation. Later, he went to London to try to persuade the British government to change the conditions, especially the taxes, that later led the American colonists into rebellion. Whatever Benjamin Franklin’s personal feelings about the rebellion of the American states, he worked hard to make it succeed. As ambassador to France, he encouraged the French to help George Washington. After the war he attended the American constitutional congress. This was his last contribution, for he died later that year. He is still fondly remembered by Americans as one of the creators of the United States. Câu hỏi; 1.
