The materials inventors say it has a number of possible uses and someday could provide a more environmentally friendly alternative to plastic. The material, made from shrimp （虾） shells and proteins produced from silk, is called “shrilk”. It is thin, clear, flexible and strong.A major benefit of the material is its biodegradability. Plastics toughness and flexibility represented a revolution in materials science during the 1950s and 60s.Decades later，however, plastics very durability （耐用性） is raising questions about how appropriate it is for one-time products such as plastic bags, or short-lived consumer goods, used in the home for a few years and then cast into a landfill where they will degrade for centuries. What is the point of making something that lasts 1,000 years？Shrilk not only will degrade in a landfill, but its basic components are used as fertilizer （肥料），and so will enrich the soil.Shrilk has great potential, the inventors said. Materials from which it is made are plentiful in nature, found in everything ranging from shrimp shells, insect bodies to living plants. That makes shrilk low cost, and its mass production possible should it be used for products demanding a lot of material.Work on shrilk is continuing in the lab. The inventors said the material becomes flexible when wet, so theyre exploring ways to use it in wet environments. Theyre also developing simpler production processes, which could be used for non-medical products, like for computer cases and other products inside the home. Theyre even exploring combining it with other materials, like carbon fibers, to give it new properties.1. Paragraph 1 of the passage is mainly about shrilks_ .A .remarkable designB. interesting nameC. major featuresD. basic elements2. What has become a concern about plastic?A. Using it properly.B. Producing it cheaply.C. Developing its properties quickly.D. Evaluating its contributions fairly.3. According to the inventors, shrilk has great potential partly because_ .A. it can help plastic degradeB. it can be found in living thingsC. its mass production has been realizedD. its raw materials are abundant in nature4. What are the inventors doing in the lab?A. Replacing carbon fibers with shrilk. B. Testing shrilks use in wet conditions.C. Making shrilk out of used household goods. D. Improving shrilks flexibility for medical purposes.5.Which of the following can be the best title for the passage?A. Recent Progress in Environmental Protection B. Benefits of Insects in Scientific ResearchC. The Harm of One-time Products D.A Possible Alternative to Plastic1.C 段落大意题。第一段中的众多字眼，如tough,low-cost,biodegradable,thin,clear,flexible和strong等均是用来描述这种新材料特点的。而关于它的设计并未提及；这种材料的名字在本段中有所涉及，但并非本段的中心；此外，本段简单介绍了制作这种材料的物质，并未大篇幅进行讲解，也不是本段的中心。2.A 细节理解题。根据第二段的第三句话可知，塑料的耐用性让人们对如何合理、恰当地使用诸如塑料袋等一些一次性产品的问题开始关注。A项意为“恰当地使用”，是人们所关注的问题，符合题目要求。B项意为“便宜地生产”；C项意为“迅速发展其性能”，D项意为“公平地评估它的贡献”均未在文中提及。3.D 细节理解题。从第四段中的“Materials from which it is made are plentiful in nature.”一句可以看出，新材料的发明者之所以说这种材料很有潜力，主要是因为制作它的原材料在自然界中很容易找到，有大量的原材料可供使用。4.B 细节理解题。根据文章最后一段中的“.theyre exploring ways to use it in wet environments.”可知，现在研究者正在实验室对该种材料在潮湿环境下的应用进行探索和研究。5.D 主旨大意题。A选项意为“在环境保护方面的最新进展”，题目太宽泛；B选项意为“科研中昆虫的好处”，并未提到新材料；C选项意为“一次性产品的危害”，尽管文章中有所涉及，但文章大部分的笔墨都是围绕这种新材料进行的描述，故该标题太片面；D选项意为“塑料的一种可替代品”，符合文章主旨。 Here is your best chance to travel around the UK in 2012:More than 200 B&Bs (bed & breakfast) across England, Scotland, Wales and Northern Ireland are selected to offer you amazing services for your stay at their lowest prices! Dont miss it. Just collect the vouchers (活动券) in our B&B Daily printed from 01/04/2012 to 07/04/2012 and book the stays for your travel following the terms and conditions below:The offer includes a room for the night and a breakfast the next morning.The offer is of two kinds：20 per room, per night, valid (有效的) during stay period of 02/04/201231/05/2012 and then again 01/09/201231/10/2012；35 per room, per night, valid during stay period of 01/06/201231/08/2012.The offer is valid for a basic twin or double room only.The stay must be booked directly with the chosen B&Bs before 28/04/2012.Each voucher can only be used by the holder to book one room for one night.If voucher holders book either the 20 or 35 per room per night, any additional services such as lunch, evening meal or activities may require an extra charge. But these are not required in order to take up the offer. Please check directly with your chosen B&Bs to see what extra services are available.Vouchers must be presented on arrival. If no vouchers are presented, the B&Bs may reserve（保留） the right to charge at full price for every night of stay.Vouchers may not be used together with any other offer.The voucher holders must pay for the stay in full at the time of booking. Additional 10 may be paid to confirm (确认) the booking and will be returned on arrival. The B&Bs reserve the right to refuse voucher holders bookings for people under the age of 18.1. The voucher can be used for a stay at the chosen B&B on _.A.09/01/2012B.04/02/2012C.01/03/2012D.28/04/20122. How much should be paid for a two-night stay in October 2012 at a chosen B&B?A.70.B.40.C.35.D.30.3. What right do the B&Bs reserve?A. To charge extra 10 for bookings with no vouchers. B. To refuse bookings for guests under the age of 18.C. To charge at full price for stays not confirmed.D. To request extra charges as tips.4. By taking up the offer, the voucher holders can choose to _.A. book either a basic twin or double room at the chosen B&BsB. have lunch or evening meal without paying extra moneyC. use the B&B offer together with other offersD. book the stays through B&B Daily1.D 细节理解题。由第一段最后活动券的印制时间从2012年4月1日到2012年4月7日及“The stay must be booked directly with the chosen B&Bs before 28/04/2012.”可以得出答案。2.B 数字计算题。从“20 per room, per night.then again 01/09/201231/10/2012”可知，从2012年9月1日到10月31日之间，每个房间每晚的价格是20英镑，因此两个晚上的价格是40英镑。3.B 细节理解题。从最后一句“The B&Bs reserve the right to refuse voucher holders bookings for people under the age of 18.”可以得出答案。 4.A 细节理解题。联系文章中的“The offer is valid for a basic twin or double room only.”可以得出答案。任务型读写 阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。注意：每个空格只填一个单词。In the past 100 years Asian Americans have become the fastestgrowing US. minority.As their children began moving up through the nations schools，it became clear that a new class of academic achievers was forming.Their achievements are reflected in the nations best universities，where mathematics，science and engineering departments have taken on an Asian character.This special liking for mathematics and science is partly explained by the fact that AsianAmerican students who began their education abroad arrived in the US. with a solid grounding in mathematics but little or no knowledge of English.They are also influenced by the promise of a good job after college.Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively.And the return on the investment in education is more immediate in something like engineering than with an arts degree.Most AsianAmerican students owe their success to the influence of parents who are determined that their children take full advantage of what the American educational system has to offer.An effective measure of parental attention is homework.Asian parents spend more time with their children than American parents do，and it helps.Many researchers also believe there is something in Asian culture that promotes success，such as ideals that stress family values and emphasize education. Both explanations for academic success worry Asian Americans because of fears that they form a typical racial image.Many can remember when Chinese，Japanese and Filipino immigrants were the victims of social separation.Indeed，it was not until 1952 that laws were laid down giving all Asian immigrants the right to citize
