Sometimes, you just can't help it. Maybe you're watching a sad movie, or thinking about the friend who moved away. Next thing you know, there's a lump in your throat, your eyes are watering, and you have tears running down your cheeks.A professor of psychology at Tilburg University, in the Netherlands,has studied crying.According to Vingerhoets, there're three types of tears. Basal tears are the first type. They act as a protective barrier between the eye and the rest of the world.Next are reflex tears. They wash your eyes clean when something gets in them. Finally, there're emotional tears. “These are released in response to emotional states,” explains Vingerhoets.Scientists believe crying has something to do with how humans developed and learned to depend on each other. “Humans are very complex social creatures,” says Lauren Bylsma, a professor from Pittsburgh University, in Pennsylvania. “It seems that tears can make them get help and support from others.”She says another reason why we weep is that humans have the longest developmental period of almost any animal. It takes a long time to grow up.Vingerhoets agrees. “I think that the reason why humans shed(流出)emotional tears has to do with our prolonged(延长的) chi ldhood,” he says. “That's the time when we're still dependent on adults for love,protection and care. The major advantage of tears is that you can target them at a specific person.”Vingerhoets says this ability could have come in handy in prehistoric times, when humans were living among dangerous animals. Loud crying could attract predators(捕食者). Tears were a safer way to get attention. “In this case, it's better to use a silent signal to ask for help,” he says. Vingerhoets and Bylsma do frequent studies to better understand why humans cry.1.The tears mentioned in Paragraph 1 should belong to ________.A.basal tearsB.reflex tearsC.happy tearsD.emotional tears2.What is Vingerhoets' attitude to the effects of tears?A.Passive.B.Positive.C.Doubtful.D.Indifferent.3.The underlined phrase of “a silent signal” probably refers to ________.A.a written languageB.predatorsC.tearsD.loud crying4.What is the best title of the text?A.Types of TearsB.Precious TearsC.Secrets of TearsD.On Tears参考答案： 1.D; 2.B; 3.C; 4.C解析： 1.[推理判断题。

Spider(蜘蛛) webs have something in common with guitar strings. The long, thin strings on a guitar can vibrate(振动). They move back and forth, or from side to side. So do webs made by spiders. The lines of silk they produce can carry vibrations. This movement gives the small creature information about what landed on the web.Spiders have eight legs and usually eight eyes. The animals build webs with their own soft, naturally­made silk. And much like playing the strings of a guitar, a spider can send out vibrations across its web over many different frequencies(频率). Spiders catch their food, usually insects in their webs. They make small movements, which spread across their webs. The vibrations can give the spider details about what is caught in the web—maybe a possible mate，or something tasty to eat.Vibrations are not just used to spot what is for dinner. They are also important in courtship(求爱), so lots of males will actually create a very specific kind of musical pattern which the females can use to determine not only that they’re a male, but they’re the right species, and whether they might want to mate with them as well.Spiders make their own vibrations to find out the condition of the webs. By controlling the tightness of the material, they can effectively control how information is getting to them when they hang out in the middle of the web.Spiders have a special ability to shape the physical nature of their self­made materials and creations. Scientists think that spider silk may have changed over time for this purpose.【解题导语】本文介绍了蜘蛛吐出的蛛丝可以传播不同频率的振动，这些振动让它们知道蜘蛛网上落下了什么东西并且这些振动在求爱中也非常重要。

Most scientists agree that such changes are necessary to protect our environment from further harm.The construction industry consumes a large quantity of energy and resources and creates a huge amount of pollution. In the United States, building and development account for 39% of the country’s total energy use, 12% of total water consumption,68% of total electricity consumption and 38% of carbon dioxide emissions（二氧化碳排放）, according to the Environment Protection Agency.Green buildings use less energy, water, create less waste, and are healthier to live, work, and go to school in than standard buildings. Builders of green buildings use techniques that use resources more efficiently during the entire building cycle—construction, restoration, operation, maintenance（维护）and demolition（拆毁）—than those who construct more regular buildings.The environmental benefits of building green include the protection of ecosystems （生态系统）and biodiversity, improved air and water quality, less waste flowing into streams, and the protection of natural resources. Green buildings can also result in lower operating costs because they typically use less energy and fewer materials and improve indoor air quality, improving the health of people who live in such buildings.The process of building green includes technical and artistic planning with nature protection in mind. Building designs often reflect the surrounding environment and natural resources and use renewable building materials such as bamboo and straw. In addition, recycled resources found locally are used for green buildings, reducing the cost and air pollution associated with transporting materials over long distances.Careful site selection is important to minimize（最小化）human impact on the surrounding environment. For example, placing a structure in an area that allows itto take advantage of cool breezes（微风）and sunlight can reduce energy use and expenses. More energy and expense are needed for larger buildings as well, so it is important to build small.Other features of green buildings often include energy and water conservation, recycling, and waste reduction. In addition, renewable energy sources such as solar power, hydropower（水能）and wind power are used for heat and electricity, which greatly reduces costs and decreases the impact on the environment.1.What is the text mainly about?A. The necessity of promoting energy efficiency.B. The process of building green buildings.C. The benefits and features of green buildings.D. Green buildings effects on the environment.2.According to the text, green buildings refer to the buildings that______.A. produce no wasteB. only use clean energyC. are made of recycled materialsD. use energy and resources more efficiently3.Which of the following statements is TRUE about green buildings?A. They rely on fossil fuels and solar power for heat and electricity.B. Small buildings are less efficient in energy use than larger ones.C. The ecosystem has to be considered when building a green building.D. They are difficult to maintain and thus need more operating costs.4.Why are green roofs used ?A. They fit the surrounding environment wellB. They are cheaper than other kinds of roofsC. They can keep natural water for use in everyday lifeD. They can help to control the temperature in the building well【文章大意】在本文中作者主要分析了green building的诸多好处和对环境的巨大的保护作用，呼吁人们多建设这样的绿色的建筑。
