She cooked traditional food， liked dressing up traditionally and thus was fond of traditional way of shopping. She loved going to the market and going from one shop to another to find out what suited her best. She could walk miles when it came to shopping along with her friends. She was familiar with all the local markets and shops and by now knows very well where she can get best discounts and material. However， now she begins to feel her age and gets tired when she goes out in the market. So one day I decided to introduce a new shop to her， a shop that is much bigger than her usual markets and where she gets better discounts. Yes， I am talking about the online gift stores. She has basic knowledge of computers and can operate a laptop. Initially (起初) she was doubtful about shopping from these online gift shops and wasnt too sure about the quality of the products. One fine day I decided to get some branded things for her first so that she could build trust in these shops. I ordered a Timex watch for her along with a Sisley handbag. She had never bought things online but when they were delivered as gifts， she jumped for joy. She could not believe that I had ordered these gifts for her despite her being not much positive about online shops. However， after she saw both the products， she believed that these online gift shops would send the promised brand and products. She loved her new watch and the handbag. After this incident she ordered a gift for her friends wedding anniversary. She chose a gift basket that could be made to her requirements. They sent a beautifully decorated basket with fine wines and chocolates. The basket was so carefully decorated that it immediately became her friends favorite gift.

These problems include water shortages， poor water quality and floods. The report says the problems will increase the risk of instability and the failure of governments. However， countries are seen as unlikely to go to war over water and instead water tensions have historically led to more water-sharing agreements than violent conflicts. But beyond 10 years， it warns that some governments could use water as a weapon to pressure others. And water could also be used to “further terrorist objectives.” The report says the areas that will be most affected by water problems are North Africa， the Middle East and South Asia. Secretary of State Hillary Clinton announced the report last Thursday on World Water Day. The National Intelligence Council wrote the report based on a National Intelligence Estimate she requested a year ago. HILLARY CLINTON: “Reliable access to water is essential for feeding the hungry， running the industries that promote jobs， generating the energy that fuels national growth， and certainly it is central when we think about how climate change will affect future generations.” The report says water-related problems could distract countries from working with the United States on important policy goals. But it also predicts an increased demand for American aid and expert help to solve those problems. That demand could create opportunities for leadership and influence. The report says， “Water shortages， poor water quality， and floods by themselves are unlikely to result in state failure.” But these could combine with poverty， social tensions， environmental problems， poor leadership and weak governments to produce social disorder. And that combination could cause state failure. The report predicts that from now through 2040， “water shortages and pollution probably will harm the economic performance of important trading partners.” During the next 10 years， it says， the loss of groundwater supplies in some agricultural areas will create a risk to national and global food markets. These shortages will be a result of poor management. Agriculture uses about 70 percent of the worlds fresh water. The report says technology that reduces the amount of water needed to grow crops will offer the best defense against shortages.5. We can learn from the first two paragraphs that in the next ten years_.A.governments could fight for water in the war.B. water tensions will possibly lead to violent conflicts.C. governments will face the risk of instability and failure.D. the Middle East will be most affected by water problems.6. According to Hillary Clinton， which of the following makes the government pay great attention to water problems？A. Water-sharing agreements.B. More job opportunities abroad.C. New kinds of energy. D. Effects of climate change.7. Some agricultural areas will suffer the loss of groundwater supplies due to _.A. climate change B. water pollutionC. poor management D. a waste of water8. To defend against water shortages in agriculture， we should _.A. reduce the use of fresh water B. develop technology that saves waterC. turn sea water into fresh water D. depend more upon industryCThis week， President Obama said he now supports same-sex marriages. He became the first sitting American president to express that opinion. Earlier he had said his thinking on the issue was “evolving”.Reaction in Congress was mixed. Nancy Pelosi， the leader of the minority Democrats in the House of Representatives， welcomed the news. NANCY PELOSI: “Americas children and families and workers saw history being made right before their very eyes: the president of the United States advancing civil rights in our country.”But Speaker John Boehner and other Republicans in the House said the president was sending the wrong message at the wrong time. JOHN BOEHNER: “I believe that marriage is the union between one man and one woman. And the president， the Democrats can talk about all this all they want. But， the fact is， the American people are focused on our economy， and they are asking the question: where are the jobs？” House Republicans are leading a court case against the administration for not defending a federal law called the Defense of Marriage Act. That nineteen ninety-six law defines marriage as between one man and one woman. In the Senate， Republicans did not say much about the presidents announcement. Instead， they stressed the need for jobs. Democratic Majority Leader Harry Reid said he would support same-sex marriage if the issue were put to voters in his home state of Nevada. Mr. Obama received strong support from politically influential gays and lesbians in the 2008 campaign. His re-election campaign says donations from both groups have greatly increased since his announcement.Mitt Romney， the likely Republican presidential candidate， opposes same-sex marriage. He said: My view is that marriage is a relationship between a man and a woman， and that is the position I have had for some time and I dont intend to make any adjustments at this point. Support for same-sex marriage has grown in recent years， especially among younger people. A recent Gallup public opinion survey suggested that Americans are now evenly split on the issue. Gallup first asked the question in nineteen ninety-six. That year only twenty-seven percent of people said they supported same-sex marriages. But Mr. Obama said he still supports the right of individual states to decide the marriage issue. He spoke a day after a large majority of voters in North Carolina approved a state constitutional ban on homosexual marriage. Currently， six of the fifty states and the District of Columbia allow same-sex couples to marry. 9. What does this passage mainly tell us？A. Different attitudes towards Obamas support for same-sex marriages.B. The defense of marriage Act in the United States.C. A new trend of marriages in the United States.D. Different ideas about marriages in the United States.10. What is Nancy Pelosis reaction to same-sex marriages？A. NegativeB. SupportiveC. NeutralD. Passive11. From this passage we can infer that in the United States same-sex marriages_.A. go against The defense of marriage ActB. are seen especially among younger peopleC. are still forbidden throughout the countryD. are supposed by Democrats and supported by RepublicansDA little village used to be separated from the sea by a forest， which defended against the storms of the sea. The forest was so important but it was constantly in danger because a small group of “wicked beings” came every night to cut down some of the trees. The villagers could do nothing to stop the felling， so they were forced to constantly plant new trees to replace the fallen ones.Such was life for the tree planters for generations. Parents taught their children how to plant， and the children spent all their free time planting new trees. Each family was responsible for replanting a particular area. Failure of any family to do this would have brought the community to ruin.Of course， most of the planted trees were lost due to a thousand varying reasons， and only a small percentage reached full growth. However， so many were planted that the protective forest managed to maintain its size， despite the great storms and the cruel felling of the evil beings.But then， there was a great misfortune. One of the families died out due to lack of descendants， and their area of the forest began losing more trees. There was nothing to be done， the tragedy was inevitable， and people prepared to leave the village after so many centuries.Even so， one of the young men refused to give up the village.“I wont go，” he said.“If needed， I will start a new family that will look after that area， and I myself will go to work on it from today on.”That young man， loved by all， had no trouble in finding people to help him replant. But those helping hands all came from other areas， and soon his own area wasnt the only one in need of extra help and more trees. These new areas were helped by other families and soon no one knew whether they should look after their own area or someone elses. So to simplify things just planted trees， wherever they were needed. But they were needed in so many areas that the villagers began planting even during the night， despite their ancestral fear of the wicked tree cutters.Those night plantings meant the planters came across some of the tree cutters， only to discover that those “wicked beings” were nothing more than the frightened members of a tribe that hid themselves in the cliff caves during the day. They would come out at night to get some wood and food， so they could survive.As soon as these “beings” got to see how good it was living in a village， having food and water， and knowing how to plant trees， they begged to be accepted into the village.Each new night， the village gained more hands to help with the planting， and there were fewer tree cutters. Soon， the village filled with grateful“night beings”who mixed happily among the old families. And so great was their influence that the forest began to expand. Day by day， the forest got bigger and big
