Aral Sea The Aral Sea is an inland lake that lies to the north of Uzbekistan and to the south of Kazkhstan. Its name literally (按字面) means “the sea of island” in the Turkic language. Thus，its name refers to the many islands that dotted it in the past. Although the Aral Sea occupied a vast area of about 68，000 square km for a long period of time，but it’s believed to be less than 10% of its original site. Caspian Sea The Caspian Sea is also an inland lake. Often regarded as the largest lake in the world，the Caspian Sea is located between the continents of Asia and Europe. The Caspian Sea is an enclosed water body，it is called “sea” probably because of its massive size of 371，000 square km and its saltiness. Salton Sea Located in California，US，the Salton Sea is a rift lake that is saline in nature. Several rivers，creeks，agricultural runoffs，and drainage systems feed this lake. The Salton Sea encompasses (包括) an area of 890 square km，making it the largest lake in California. Sea of Galilee The Sea of Galilee is a freshwater lake with “sea” in its name. It occupies an area of 166.7 square km in Israel. It is the second­-lowest lake in the world after the Dead Sea with the surface elevation ranging from 705ft to 686ft below sea level. The Jordan River is the primary source of water for the Sea of Galilee. Underground springs also feed water to the lake. 语篇解读　本文是一篇应用文。文章主要介绍了世界上几个被称为海洋的湖泊。 1．Which of the four is the second biggest in the world？ A．Aral Sea. B．Caspian Sea. C．Salton Sea. D．Sea of Galilee. 细节理解题。根据Aral Sea中“... about 68，000 square km... ”，Caspian Sea中“... 371，000 square km... ”，Salton Sea中“... 890 square km... ”及Sea of Galilee中的“... 166.7 square km... ”可知，四个中第二大的是Aral Sea。故选A项。 √ 2．Which of the following is TRUE according to the passage？ A．The Aral Sea belongs to Turkey. B．The Caspian Sea is the biggest inland lake in the world. C．The Salton Sea is the biggest freshwater lake in California. D．The Sea of Galilee is the second largest lake in the world. 细节理解题。根据Caspian Sea中的“The Caspian Sea is also an inland lake. Often regarded as the largest lake in the world，the Caspian Sea is located between the continents of Asia and Europe.”可知，里海是世界上最大内陆湖。故选B项。 √ 3．Where can the text be found？ A In a history book. B．In a novel. C．In a biography. D．In a geography magazine. 文章出处题。根据第一段“People are always full of imagination about... or may be beautiful or magnificent lakes.”以及下文介绍了几个被称为海洋的湖泊。由此推知，本文可能来自地理杂志。故选D项。 √ B The Earth is losing some of its major freshwater supplies. But the water is not in lakes or rivers. They are called “aquifers (含水层)”．Some aquifers are so deep that water from very heavy rains cannot reach them through all the rock and dirt. Many aquifers provide irrigation (灌溉) water for crops. The freshwater is helping farmers in many countries. But a new report says some aquifers are being emptied. Irrigated agriculture is responsible for about 80 percent of freshwater use worldwide. A growing part of that comes from underground aquifers because of dry weather or farmers’ growing crops in areas with little rainfall. But researchers say taking water from aquifers is creating a large problem. Scientists warn that there is not much that can be done to repair them. It is difficult to measure ground­-water and to know how much water there is and where it is，because it is so deep underground. The water from these aquifers may not be replaced for hundreds of years. The report says some countries use the most non­-renewable groundwater for agricultural production. If China and India use up the groundwater they need to feed their populations，they would be forced to buy more food. This increased demand could cause food prices to rise. The study shows that，while countries like Somalia are dealing with little rainfall，the world may someday face an underground drought. It’s a global issue. We don’t have any great solutions or strategies to deal with this. So，at least，we need to have discussions to come up with new ways，new strategies that recognize this problem and manage how we might adjust our policies. Any strategy must balance the short-­term need for food with the long-­term survival of the Earth’s aquifers. 语篇解读　本文是一篇说明文。文章主要介绍了目前全球存在地下蓄水层正在被掏空的问题，我们需要讨论想出新方法、新策略。 4．Why is it tough to recover underground water？ A．More water is drawn than it is added. B．Researchers have no way to know about it. C．Underground is too deep for rainwater to reach. D．There are more areas with little rainfall around the world. 细节理解题。根据第一段最后一句“Some aquifers are so deep that water from very heavy rains cannot reach them through all the rock and dirt.”可知含水层很深，雨水很难到达，故选C。 √ 5．What’s the final result of the disappearance of underground water？ A．Food will become more expensive. B．More people in the world will be fed on. C．It is harder to discover underground water. D．There will be less rainfall due to dry weather. 细节理解题。根据倒数第二段第二、三句“... they would be forced to buy more food. This increased demand could cause food prices to rise.”可知用光地下水会导致食物价格上涨，故选A。 √ 6．How does the author feel when stating the fact in the text？ A．Amazed. B．Concerned. C．Subjective. D．Calm. 推理判断题。根据最后一段第二、三句“It’s a global issue. We don’t have any great solutions or strategies to deal with this.”可推测，作者在文章中陈述现状时是担忧的，故选B。 √ 7．What may be the best title for the text？ A．It’s Time to Stop Using Underground Water! B．To Save Underground Water Is Everyone’s Duty C．The Earth’s Underground Water Is Being Emptied D．Man Is the Main Reason for the Lack of Underground Water 标题归纳题。根据全文内容可知，本文主要讲述了地球的地下蓄水层正在被掏空的问题，故选C。 √ Ⅱ.阅读七选五 Tips for Green Travel with Kids Traveling doesn’t mean letting go of all the eco­-friendly choices we work so hard to achieve in our daily life. Here are a few tips for green travel with kids： Booking nonstop flights whenever possible will reduce carbon emissions (碳排放).If the closest local airport doesn’t have nonstop flights to a certain place，check other local airports to see if nonstop flights are available.　1　　 Whether you’re flying or driving，it’s easy when traveling to pull into fast food restaurants for snacks. 　2　 My kids love to help plan snacks. I let them create their own snacks for the trip at home. 　3　 At the airport，keep your reusable bottles empty until you have passed through the security checkpoint (安检关卡).Fill them up on the other side of the security checkpoint.

Sometimes vacation can mean more than one shower each day—once in the morning and again after getting out of the pool. Pay attention to the number of showers and the length of showers.　5　 A．Walking is good for your health. B．Try to cut back to save water and energy. C．But you can pack healthy food from home.
