Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the question. Sunlight is solar energy. Sunlight is needed for growing plants that you eat to get energy. Sunlight is also used to make clean electricity. Burning fossil fuels to make electricity pollutes our atmosphere and rivers. Fossil fuels are expensive and limited sources of energy. Nuclear fission is used to create enormous amount of heat and electricity. However, nuclear fission forms dangerous radioactive waste. Sunlight offers many ways to get energy. A window can allow warm sunlight into your room. Solar water-heating systems can use sunlight to warm the water for your home, swimming pool and school. Sunlight also warms the Earth and causes wind. Electricity can be made by wind generators. Photovoltaic, or PV system use a type of material that converts sunlight into electricity. PV systems can power your air conditioner or a satellite like the International Space Station. PV systems are also used to run a calculator, recharge cell phones, or even power lightweight cars. Sunlight is also changed into electricity by concentrating solar power or CSP systems. CSP systems have mirrors that focus the sunlight. The concentrated sunlight turns water into steam which turns a turbine that is connected to an electric generator. A CSP system is like an electric power plant that burn coals or natural gas to create heat. But a CSP system usually use sunlight to make steam. CSP power plants can store large amounts of heat. The stored heat is used to make electricity at night. During cloud days, many CSP plants can also burn natural gas to provide the heat that is used to turn water into steam. Sunlight provides the energy needed to grow plants and make large amounts of environment-friendly heat and electricity. Solar can provide power today and for a long time in the future.This article is mainly about _____.A.Humans using sunlight to stay warm.B.The need to develop new technology for solar system.C.How the energy of sunlight is used.D.How solar energy can provide power for transportation systems.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to choose the best answer for the following questionsToday, The most universally known style of trousers for both men and women is jeans; these trousers are worn throughout the world on a variety of occasions and in diverse situations. Also called levisor denims, jeans have an interesting history, one that is intermixed with the derivations of the words jeans, denims, and levis.The word jeans is derived from the name of the place where a similar style of pants developed. In the sixteenth century, sailors from Genoa, Italywore a rather unique type of cotton trousers. In the French language, the word for the city of Genoa and for the people from that city is Genes; this name became attached to the specific style of pants worn by the sailors from this city and developed into the word jeans that today describes the descendents of Genovese sailors' cotton pants.Similar to the word jeans, the word denim is also derived from a place name. In the seventeenth century, French tailors began making trousers out of a specialized type of cloth that was developed in the city of Nimes, France, and was known as serge de Nimes. This name for the cloth underwent some transformations, and it eventually developed into today's denim, the material from which jeans are made and an alternate name for those popular pants.The word leviscome from name of a person rather than a place. In the nineteenth century, immigrant Levi Strauss came to America and tried his hand at selling heavy canvas to miners taking part in the hunt for gold in northern California. Strauss intended for this canvas to be used by miners to make heavy-duty tents. This first endeavor was a failure, but Strauss later found success when he used the heavy canvas to make indestructible pants for the miners. Levi then switched the fabric from brown canvas to blue denim, creating a style of pants that long outlived him and today is referred to by his name. A modern-day urban shopper out to buy some levis is searching for a close relative of the product that Strauss had developed years earlier. The word “descendants” in paragraph 2 could be best replaced by _____. A.bottoms B.derivations C.offspring D.antecedents
