Each passage is followed by several questions orunfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage.AThe Firegathering18-20 MayThe Firegathering festival returns to an unidentified place somewhere in the Sussex countryside this May. The ticket price is a very agreeable ￡40, an amount that the organizers promise covers only the costs of staging the event. As well as the night-club singers and dancers and circus performers, you can expect live performances from local stars. If this looks like it might be right for you, you’d be well advised to book your ticket soon; the event has sold out every year since its beginning four years ago. Sheep Music20-22 JulySheep Music started life as a garden party and has developed into a full-scale community event. Even though the advertising has always been limited to word of mouth, the huge number of people in 2005 left organizers worried that the large crowds could ruin the festival’s family feel. Luckily July sees the return of this brilliant party. The climax comes in the shape of Saturday night’s full-scale parade（游行）and fancy dress ball that you just would not expect to happen in the other sleepy Welsh borders.The Big Chill3-5 AugustTen years on and The Big Chill could very well be close to becoming a big pop festival like Glastonbury. That said, the many thousands in attendance are still able to relax in the beautiful Eastnor deer park and listen to plenty of music that would otherwise pass them by. Families have always been given a warm welcome and it’s fair to say that The Big Chill is probably the most child-friendly of all the medium-sized festivals. If you’ve never been, you should certainly go.Summer Sundae10-12 AugustAlthough only a year old this summer, Summer Sundae has quickly inspired the imagination of Leicesteks music lovers. Last year’s event was a success, noted by more than a few mentions at the UK Festival Awards. It is set in the impressive grounds of De Montfort Hall. Although the performers are still to be confirmed, the cabins are sure to be there. These small buildings are made from wood and carpets, storage space, and can fit a family for the night.56. What can we learn about The Firegathering?A. The festival will take place in a park.B. The ticket price is pleasant.C. The audience will be bigger than expected.D. A lot of national stars will perform at the festival.57. How did Sheep Music advertise itself?A. By holding a parade.B. By advertising orally.C. By giving performances.D. By holding a family party.58. Which festival will provide accommodation for the audience?A. The Firegathering.B. Sheep Music.C. The Big Chill.D. Summer Sundae.59. What is the similarity of these festivals?A. All of them entertain attendants with music.B. All of them have a long history.C. All of them need advance booking.D. All of them can be compared with Glastonbury.60. If you want to take your children to a festival, which one is the best choice?A. The Firegathering.B. Sheep Music.C. The Big Chill.D. Summer Sundae.BWith limited pocket money in hand, many Chinese college students are increasingly opting to live life ―low-cost‖. One way to save money is team-buying. Online team-buying offers huge discounts and becomes popular on campus.Li Jing, a student at China Youth University for Political Science, for example, says she often buys movie tickets on team-buying websites. But while they offer a good opportunity to save money, Li said she would ―think twice before buying them from online stores‖. Because many of them are ―a bit chaotic（混乱的）, and have fake goods mixed among them. Then why don’t the students just earn more pocket money by taking up part-time jobs? Guo Na, a teacher at the Communication University of China, said most college students were unlikely to choose work-study programs to earn pocket money because of their intensive study schedules.A kind of card called ―VELO‖has become another ideal choice for many money savers. It provides all-round discounts while dining out or shopping in general. Cao Zuyang, a student at the University of Electronic Science and Technology of China, often searches for sales online and buys things together with friends to cut down on costs. Cao once wanted to buy an electro-magnetic oven, which was on sale at a shopping website. He then asked five dormitory roommates to pitch in for the oven. Each student only paid 25 yuan.Most students find it difficult to deal with the expense of accommodation while traveling. So they choose to travel to cities where they have friends and live in their dorms. For instance, Ge Rui, a student at the Hebei University of Technology, has been to many cities where he has friends. ―Friends can act as free guides, offer me free accommodation, give me valuable tour information, and broaden my mind at the same time,‖ he said. He also had friends from other cities coming over and living with him when they visited his city.61. What does the writer mainly tell us?A. The ways of saving money on campus.B. The popularity of online team-buying.B. How to recognize fake goods online.C. How to choose a city to travel.62. Which of the following statements is TRUE?A. Li Jing is a student from China Youth University for Electronic Sciences.B. Most college students earn more pocket money by taking up part-time jobs.C. It’s not a good idea to ask five roommates to buy one oven together.D. You should think twice before buying something from online stores.63. From the passage, we can know that .A. Guo Na is against students taking up part-time jobsB. most students dislike traveling because of the expenseC. Cao Zuyang succeeds in saving moneyD. students are charged for half price when traveling64. The passage is probably taken from .A. a personal diaryB. a travel magazineC. an advertisementD. an official paper65. What do we know about the mentioned persons?A. Li Jing didn’t believe she could save money by buying something online.B. Guo Na said most of the students were lazy to take up part-time jobs.C. Cao Zuyang and his roommates bought five electro-magnetic ovens.D. Ge Rui saved much money when traveling in other cities.CPlastic is one of the most important technological discoveries of the 20th century. However, it may soon be replaced. The new development—liquid wood—can replace plastics in all branches of modern industries.Plastic as a material enjoys the biggest demand in the modern world, but it does have a number of drawbacks. First and foremost, plastic isn’t recyclable. Secondly, it contains toxins（毒物）helping develop cancerous diseases. Finally, it’s made of oil and oil reserves aren’t endless.The liquid wood technology is likely to replace plastic and provide mankind with new materials for many years ahead. Norbert Eisenfreich, a senior researcher at the Faunhofer Institute for Chemical Technology (ICT) in Germany, said that arboform, the new material, is made of lignin（木质素）, which can be obtained from soft tissues of wood. Once mixed with several other materials, it turns into solid and non-toxic alternative for plastics.ICT team leader Emilia Regina Inone-Kauffmann said the wood-working industry separates wood into three basic components, including lignin. Lignin isn’t used for the production of paper. Specialists of ICT mixed lignin with several natural materials and thus invented the material which could be melted and molded（铸型）.When solid, arboform looks like plastic and possesses the qualities of polished wood. It can be used for the production of any items. Arboform is already used for the production of car parts which require extra strength. In addition, liquid wood can be recycled repeatedly. The material preserves all of its qualities even if it’s reprocessed ten times.However, the new invention doesn’t enjoy an extensive use due to the high content of sulphur（硫）in it. German researchers are sure to reduce the amount of sulphur by 90 percent very soon to make arboform usable for home needs.66. According to the passage, plastic .A. plays a big role in the modern worldB. helps to protect our environment in some wayC. has been replaced by the newly discovered materialD. helps us to reduce the use of petrol67. The underlined word ―alternative‖ in Paragraph 3 refers to .A. lignin or arboformB. plasticsC. mixture of several materialsD. soft tissues of wood68. What’s the advantage of arboform over plastics?A. It is easily made from natural oil.B. It is more widely used in household.C. It is recyclable and friendly to the environment.D. It contains no poisonous materials.69. It can be concluded that German researchers will focus their future work firstly on .A. the material’s extensive useB. the content of sulphur in arboformC. the production cost of arboformD. the qualities of liquid wood70. What’s the main purpose of the passage?A. To advertise the new material—arboform.B. To introduce liquid wood which will replace plastic.C. To advertise new products made of arboform.D. To show readers how to produce arboform.Part IV Writing (45 marks)Section A (10 marks)Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage. Write NO MORE THAN THREE WORDS for each answer.Hearing a child say their first word is a magical moment. Children are eager to learn, and the more they are encouraged, the more they will try. Here are some tips on how to encourage speech development.Early encouragementIt is essential to speak to a child from their newborn stage. Pronounce words clearly so that children can grasp the spoken word. This will help them learn to speak.Positive wordsChildren engage more when it is fun and interesting, and when their efforts are acknowledged. Be positive by giving recognition when new words are learned, and emphasize how exciting these mom ents are. When a word is spoken that isn’t completely clear or is mispronounced, it should be repeated clearly. Never pay too much attention to mistakes, and instead strengthen correct pronunciation by repeating the word directly after the child.ReadingA fun way to encourage speech development is by sharing books with children. Reading aloud to a child introduces them to new words and ideas.Singing nursery rhymesChildren are often enticed（吸引）by music, as it grabs their attention and attracts their interest. Singing nursery rhymes will often encourage speech development, as children tend to be able to learn and memorize the words when they are sung. There are many different nursery rhymes that make youngsters smile.CommunicationAlways make eye contact when speaking to a child to get them engaged. Repetition is important to help encourage speech development. Facial expressions and gestures, as well as tones are just as important to provide understanding. Acknowledge their efforts and attempts to speak, and repeat words slowly to allow them to follow the mouth movements.Learning to speak and communicate with others is a milestone（里程碑）and a fun journey for the child. Every parent adores the sound of their baby babbling（儿语）and looks forward to their first words. But this development does not happen by accident and parents can play a great contributory role in their children’s speech development.Title: How to encourage children’s 71.Section B (10 marks)Directions: Read the following passage. Answer the questions according to theinformation given in the passage.Blood donation is a wonderful thing done by us. To begin with, extensive studies show that blood plays a vital role in medical operation. In donating our blood we are actually saving the precious lives of the sick. Next, being a healthy person, losing 200ml of blood is only a small sacrifice and helps to improve our metabolism (新陈代谢). Finally, donating blood helps us in forming good character and developing our sense o f social responsibility. Blood donation isn’t a complicated issue, but we need tokeep a few instructions in mind.First don’t go for blood donation with an empty stomach. We can eat anything and after having a right diet we’ll feel strong and comfortable to donate blood. For the required hemoglobin (血色素) in the body, we can drink lots of fruit juice. For a good blood flow in the body, let’s drink at least 6-7 glasses of water daily. Completely avoid taking alcohol or caffeine a day before and after donating our blood. We shouldn’t smoke half an hour b efore making blood donation.When we’re going for blood donation, first tell the nurse to check our hemoglobin level. During the injection we need to take a deep breath and try to calm ourselves down. During blood donation, keep ourselves cool and calm.Blood donation is a very fast process, but we need to take care of ourselves after blood donation. For example, take a rest for 15 minutes after the donation. Eat something and drink juice leaving the blood donation centre. Make sure not to skip meals after blood donation.
