AArriving in Sydney on his own from India, my husband, Rashid, stayed in a hotel for a short time while looking for a short time while looking for a house for me and our children.During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport.He reported the case to the police and then sat there ，lost and lonely in strange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband ’s name and was asking him a lot of questions. Then he said they had found a pile of papers in their trash can （垃圾桶）that had been left out on the footpath.My husband rushed to their home to find a kind family holding all his papers and documents. Their young daughter had gone to the trash can and found a pile of unfamiliar papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half –written letter in the pile in which my husband had given his new telephone number to a friend.That family not only restored the important documents to us that day but also restored our faith and trust in people. We still remember their kindness and often send a warm wish their way.姓名______________________ 准考证号__________________________________21. What did Rashid plan to do after his arrival in Sydney?A.

In Search of New Friends.BSince the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that tim e there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.But what began as nothing important in public affairs has grown into a social movement. Business people, political leaders, university professors, and especially millions of grass–roots Americans are taking part in the movement. “The understanding has inc reased many, many times,”says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions （排放）from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons. The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking “has become part of practices.Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.Twenty–five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” say Bruce Anderson.25. According to Anderson, before 1970, Americans had little idea about _________.A. the social movementB. recycling techniquesC. environmental problemsD. the importance of Earth Day26. Where does the support for environmental protection mainly come from?A. The grass–roots level.B. The business circle.C. Government officials.D. University professors.27. What have Americans achieved in environmental protection?A. They have cut car emissions to the lowest.B. They have settled their environmental problems.C. They have lowered their CO levels in forty cities.D. They have reduced pollution through effective measures.28. What is especially important for environmental protection according to the last paragraph?A. Education.B. Planning.C. Green living.D. CO reduction.COne of the latest trend（趋势）in American Childcare is Chinese au pairs. Au Pair in Stamford, forexample, has got increasing numbers of request for Chinese au pairs from aero to around 4,000 since 2004. And that’s true all across the country.“I thought it would be useful for him to learn Chinese at an early age” Joseph Stocke, the managing director of a company, says of his 2–year old son. “I would at least like to give him the chance to use the language in the future,” After only six months of being cared by 25–year–old woman from China, the boy can already understand basic Chinese daily expressions, his dad says.Li Drake, a Chinese native raising two children in Minnesota with an American husband, had another reason for looking for an au pair from China. She didn’t want her children to miss out on their roots. “Because I am Chinese, my husband and I wanted the children to keep exposed to（接触）the language and culture.” she says.“Staying with a native speaker is better for children than simply sitting in a classroom,” says Suzanne Flynn, a professor in language education of Children. “But parents must understand that just one year with au pair is unlikely to produce wonders. Complete mastery demands continued learning until the age of 10 or 12.”The popularity if au pairs from China have been strengthened by the increasing numbers of American parents who want their children who want their children to learn Chinese. It is expected that American demand for au pairs will continue to rise in the next few years.29. What does that term “au pair” in the text mean?A. A mother raising her children on her own.B. A child learning a foreign language at home.C. A professor in language education of children.D. A young foreign woman taking care of children.30. Li Drake has her children study Chinese because she wants them _________.A. to live in China some dayB. to speak the language at homeC. to catch up wit other childrenD. to learn about the Chinese culture31. What can we infer from the text?A. Learning Chinese is becoming popular In America.B. Educated woman do better in looking after children.C. Chinese au pairs need to improve their English Skills.D. Children can learn a foreign language well in six months.DMetro Pocket GuideMetrorail（地铁）Each passenger needs a farecard to enter and go out.

2014年全国高考理综试题及答案-新课标2卷(解析版)
2014年普通高等学校招生全国统一考试（新课标Ⅱ卷）理科综合试卷第Ⅰ卷一、选择题(每小题6分，只有一个符合题意)1、关于细胞的叙述，错误的是A．植物细胞的胞间连丝具有物质运输的作用B．动物细胞间的粘着性与细胞膜上的糖蛋白有关C．ATP水解释放的能量可用于细胞内的吸能反应D．哺乳动物的细胞可以合成蔗糖，也可以合成乳糖【答案】D【解析】本题考查的是细胞结构和化学成份这两个知识点。
细胞膜的功能之一信息传递，其方式如通过胞间连丝，A项正确。
糖蛋白与细胞相互识别有关，又与细胞间的粘着性有关，癌变后的细胞由于糖蛋白减少所以易转移和扩散， B项正确。
ATP水解后有能量可用于各项生命活动，如电能、热能等其他细胞内的吸能反应，C项正确。
蔗糖是植物内的一种二糖，在哺乳动物的细胞不可以合成，故D项是错误的。
2.同一动物个体的神经细胞与肌肉细胞在功能上是不同的，造成这种差异的主要原因是A．两者所处的细胞周期不同B．两者合成的特定蛋白不同C．两者所含有的基因组不同D．两者核DNA复制的方式不同【答案】B【解析】本题考查的是细胞分化这个知识点。
同一生物个体的不同细胞，在形态结构与功能上是不同的，是基因的选择性表达的结果，其DNA分子或遗传物质并没有差异，A、C、D都不正确，基因的选择性表达之后，形成了不同的蛋白质，使各细胞中的蛋白质有所不同，故B项正确。
3.关于在正常情况下组织液的生成与回流的叙述，错误的是A．生成与回流的组织液中氧气的含量相等B．组织液不断生成与回流，并保持动态平衡C．血浆中的有些物质经毛细血管动脉端进入组织液D．组织液中的有些物质经毛细血管静脉端进入血液【答案】D【解析】本题考查的是内环境成份这一个知识点。
内环境中的各种成份是处于动态平衡之中，氧气在生成的组织液中会高于回流的组织液，因为组织细胞在不断消耗氧气，这样氧气就能以自由扩散形式从组织液进入组织细胞，故A不正确，B正确。
因为毛细血管壁有一定通透性，所以血浆中的小分子物质可以透过毛细血管动脉端进入组织液，同理，组织液中的有些物质经毛细血管静脉端进入血液，血浆与组织液可以发生物质相互渗透。

故选B。
【解析】根据倒数第二段最后一句可知，那位女孩的父母是在一封写了一半的信里发现作者丈夫留给朋友的新电话号码的。
故选C。
23.【答案】D【解析】根据“not only...but also...”所连接的“restore”后面的宾语，并结合上文可知，小女孩一家人把那些重要的文件还给了作者的丈夫，所以此处应选D项，意为“恢复”。
24.【答案】C【解析】文章主要讲述了作者的丈夫丢失的重要文件被人扔在垃圾箱里面，然后又被一家好心人捡到重新归还给作者的丈夫的故事，这使作者的丈夫又重拾了对人性的信任。
作者丈夫的这些东西之所以能够失而复得离不开垃圾箱这一线索。
因此C项做标题最恰当。
文章大意：本文是一篇说明文，主要介绍了“地球日”的来历以及它在唤起人们的环保意识、节能减排、保护环境等方面所做的贡献。
25.【答案】C【解析】根据文章第一段可知，在1970年以前人们不知道什么是“环境”，更不知道环境问题。
故选C。
26.【答案】A细节理解题。
难度中等。

C项干扰性很强，但是与原文第三段第二句“The number of cities producing CO beyond the standard has been reduced from 40 to 9.”不符，原文意思是说CO超标的城市数量从40个减少到9个。
