ALooking for something entertaining to do? Check out some wonderful festivals around the world. Koningsdag-The NetherlandsKoningsdag or King's Day is a national holiday in the Kingdom of the Netherlands. It is celebrated on April 27( April 26 if the 27this a Sunday), the date marking the birth of King Willem-Alexander. Orange is the national color，and the streets become a sea of feather boas（羽毛围巾）and body paint as crowds gather in the plazas and on the boats in the rivers. Amsterdam is the center of this outdoor party, with many live music events, but nearly every town is alive with orange on this day.Thai National Elephant Day-ThailandThai National Elephant Day is a national holiday in Thailand. Thai National Elephant Day has been celebrated on March 13th of every year since 1998. Because the elephant is the national animal of Thailand, it is highly respected and treasured. During the festivals elephants are honored during a ceremony in which they are fed with bananas, other fruit, and sugar cane.The Fire Festival-ShetlandOn the last Tuesday of January the entire town of Lerwick, Shetland is in flames. At the festival,you'll find yourself sitting, dancing, or stumbling around the largest bonfire you've ever seen in your life. The festival lasts only one day but takes the entire year to plan. Be prepared for an evening of singing, dancing, and fast-paced activities,and don't worry about making it to work next day-it's a national holiday!Holi-IndiaHoli, the festival of colors, is a Hindu celebration full of joy and one of India's most important holidays. On the last full moon day of the lunar month, usually late February or early March, the air is full of bright-colored powder. The festival is celebrated differently throughout the country, with bonfires and music, but the cheerful spirit is common throughout Hindu communities around the world.1.The festival celebrated on March 13th in Thailand is held toA.help people relax by singing and dancingB.show people's respect for their QueenC.show Thai people's respect for elephantsD.ask people to protect endangered animals2.Why don't people have to worry about working the day after the Fire Festival?A.Because the festival ends very early at night.B.Because people are allowed to sleep at work next day.C.Because the activities are too simple to get people tired.D.Because people don't have to go to work next day.3.Where should you go if you are interested in the festival of colors?A.The Netherlands.B.India.C.Shetland.D.Thailand.BWashington is home to lots of trees and lots of wood-burning stoves too. But what if you lived there and couldn't cut wood or couldn't afford to pay anyone to do it?Luckily,Shane McDaniel and his twin sons, Harrison and Henry McDaniel，21，are happy to lend an ax（斧子）．The three men cut truckloads of wood and then give the wood to those in need.The idea was put forward by Shane as a father-son bonding project. He wanted to pass along the feeling his father Jackson and he shared while they cut wood, so he and the twins spent the summer doing their deeds.The result was a great wall of wood piled up around their house in Lake Stevens, about 35 miles outside of Seattle.To buy that much would cost about $10,000.It was too much for the McDaniels to use themselves,and when the weather turned cold that November, Shane started thinking of others. He posted a request on a social networking site:“If you are in need of firewood and cannot afford it, please message me personally! Please heIp me and my boys make sure no one goes cold in ourneighborhood.”The response was immediate. One man offered to donate a wood-burning stove. Others raced to provide more wood for the pile. Single dad Peter Ticer, 29, and his four-year-old daughter depend on a wood-burning stove as their unique source of heat. So it was a relief to receive a truckload of firewood from the McDaniels before the holidays. “To get that much wood moved me to tears” he said.“So much stress and anxiety off my shoulders. I couldn't be more thankful.”Giving is the reward. It has nothing to do with how well it's received; it's about how much it's needed.4.Which of the following best describes the McDaniels?A.Energetic.B.Hard-working.C.Considerate.D.Mean.5.What does “father-son" in Paragraph 2 refer to?A.Shane and Harrison.B.Jackson and Shane.C.Harrison and Henry.D.Shane and the twins.6.Why did Shane post the message on the Internet?A.To advertise the wood they cut.B.To help those in need.C.To get wood-burning stoves.D.To ask for others' help.7.What is the main idea of the text?A.A family's firewood warms their neighborhood.B.Cutting down trees teaches a family life lessons.C.No one goes cold in the McDaniels' community.D.Giving is a tradition of cheering up those in need.CResearchers at CU-Boulder have developed a wearable device that changes the human bodyinto a biological battery. The device is stretchy（有弹性的）enough that you can wear it like a ring,band or any other thing that touches your skin. It also taps into a person's natural heat-employing thermoelectric generators to change the body's internal temperature into electricity. “In the future, we want to be able to power your wearable electronics without having to include a battery,” said Jianliang Xiao, an associate professor at CU-Boulder.The concept may sound like something out of The Matrix film series, in which a race of robots have enslaved humans to harvest their precious organic energy. Xiao and his colleagues aren't that ambitious: Their devices can generate about 1 volt（伏特）of energy for every square centimeter of skin space-less volt per area than what most existing batteries provide but still enough to power electronics like watches or fitness trackers.Scientists have previously experimented with similar wearable devices, but Xiao's is stretchy, can heal itself when damaged and is fully recyclable-making it a cleaner alternative to traditional electronics. “Whenever you use a battery，you＇re depleting（消耗）that battery and will，eventually, need to replace it,” Xiao said.“The nice thing about our device is that you can wear it, and it provides you with constant power.”Just pretend that you're out for a jog. As you exercise, your body heats up, and that heat will radiate out to the cool air around you. Xiao's device captures that flow of energy rather than let it go to waste.“The thermoelectric generators are in close contact with the human body, and they can use the heat that would normally be sent into the environment," Xiao said.8.What does Xiao expect of his device at present?A.It will be used for medical purposes.B.It will be made smaller and wearable.C.It will change natural power into electricity.D.It will supply constant power to wearable devices.9.Why does the author mention The Matrix series in the text?A.To give an explanation.B.To make a comparison.C.To introduce a topic.D.To analyze the cause.10.What does the third paragraph mainly talk about?A.The strengths of Xiao's device.B.The convenience of using a battery.C.The replacement of wearable devices.D.The development of traditional electronics.11.What do we know about Xiao's device from the text?A.It operates with plenty of power.B.It is designed for practical use.C.It benefits people's health in a way.D.It's based on traditional electronics.DHuman activity is changing the surface and temperature of the planet. But new research shows it is also changing the sound of the Earth's oceans and seas.Scientists say the changes in the sounds of our oceans and seas affect many marine（海生的）animals-from very small fish to huge whales. Sound travels“very far underwater,” Francis Juanestold the reporter. Juanes is an ecologist at the University of Victoria and co-writer of the recent research published in a magazine.“For fish,”he explained, “sound is probably a better way to sense their environment than light.”Sounds help fish and other marine animals survive.They use sounds to communicate with each other. Sounds also help some ocean animals find food and avoid their hunters. Many ocean animals use sounds to find good places to give birth. However, increased noise from humans is making it harder for these animals to hear each other. The noise comes from shipping traffic, underwater oil and gas exploration, offshore construction, and other noisy human activities.“For many marine species, their attempts to communicate are being masked by sounds that humans have produced,” said Duarte. The marine ecologist at the RedSea Research Center co-wrote the paper with Juanes. TheRed Sea, Duarte said, is one of the world's most important shipping passages. It is full of large ships traveling to Asia,Europe, and Africa. Some fish and other animals,he said, now avoid the noisiest areas. Also, the overall number of marine animals has gone down by about half since 1970. In some parts of the ocean, scientists now record “fewer animals singing and calling than in the past-those voices are gone," said Duarte.Juanes and Duarte examined studies and research articles about changes in noise volume（音量）and frequency in the world's oceans. Then they put together a detailed picture of how the ocean soundscape is changing and how marine life is affected.Climate change, the researchers found, also affects physical processes that shape ocean sounds. These include such things as wind, waves, and melting ice.Some studies suggest that noise may cause hearing loss of marine animals. Besides, many marine animals are showing higher levels of stress due to noise, which might also affect the immune system.Scientist Juanes says sound pollution may be easier to deal with than other ocean threats.“In theory,”he said,“you can turn down or turn off the sound immediately. It's not like plastics or climate change, which are much harder to undo."12.What can we learn from the passage?A.Noise may result in hearing loss of human beings.B.Sound pollution killed most of the marine animals in the Red Sea.C.Noise can influence the communication of marine animals.D.Sound is unlikely to be a better way to sense their environment than light.13.What's the meaning of the underlined word “passages”in Paragraph 4?A.Channels.B.Addresses.C.Industries.panies.14.In the following paragraph, the author will probably tells us___A.what the main cause of climate change isB.what should be done to reduce sound pollutionC.how to record changes in noise volume and frequencyD.how to enhance the immune system of marine animals15.Which is the best title for the passage?A.The Future of Ocean ExplorationB.The Changes in the Sounds of OceansC.Sounds Help Marine Animals SurviveD.Humans Are Making Oceans Too Noisy第二节（共5小题；每小题2.5分，满分12.5分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
