It was a fine day. Jeffrey Del Monte was driving With his friend late Friday afternoon along the beach near Ramp 49 in Friso when they heard the screams of children. They surveyed the water trying to locate the screams and， two young girls were spotted apparently struggling while being swept out in a rip current（激流）.
Del Monte then swam out into the ocean and helped one of the girls who were caught in the rip current, passing her to his friend for the lengthy swim back to shore. He then went back to search for the second girl and found her in great pain before he swam back to shore, bringing the child to the beach from nearly 100 yards out.
After both girls were safe on the beach, Del Monte and his friend attended to them until Dare County Emergency Medical Services and a Cape Hatteras National Seashore Ranger arrived on the scene. The children's parents also arrived and expressed their thanks to Del Monte and his friend.
“Jeffrey Del Monte's heroic, selfless and quick actions were key to saving these two girls from a very dangerous situation," National Parks of Eastern North Carolina Superintendent David Hallac said in a statement. "His courage and expertise allowed him to perform this successful ocean rescue. "
Park officials said the incident was a reminder of how quickly ocean conditions could change, even on what appeared to be a perfect clay.
“A perfect clay on the beach doesn't always mean that it's a perfect day in the ocean, so it is important that all visitors check the beach forecast for danger and rip currents before heading to the beach and always use something that floats when in the water. If individuals do find themselves caught in rip currents, please don't swim against the currents, instead swimming out of the currents and then to shore," David Hallac said.
24. Why did Del Monte hand the first rescued girl to his friend?
A. To go to seek for the other struggling girl.
To give his friend a chance to be praised.
C. To relieve his pain caused by the current.
D. To experience the lengthy swim himself.
25. What did Del Monte and his friend do after they saved the girls?
A. They took them to hospital quickly.
B. They looked after them on the beach.
C. They drove them back to their parents.
D. They blamed them for taking the risks.
26. What is David Hallac's attitude towards Del Monte?
A. Worried,
B. Envious.
C. Appreciative.
D. Grateful.
27. What suggestion does David Hallac offer to visitors?
A. Going swimming with others.
B. Avoiding floating in the water.
C. Swimming against the currents.
D. Preparing well for beach trips.
C
A new study looks at how pets provide important support through petting, cuddles（拥抱）,and a frequent physical presence. This is especially key when people feel lonely.
The researchers interviewed 32 people aged 59 to 83 years old. Pets included dogs, cats, birds, etc. More than 90% of the people spoke about touch in the relationship with their pets. "Participants often described touch-based interactions with their pets as being comforting or relaxing in a way that contributed to their overall wellbeing,“ the researchers say, "Fo r our participants, comfort is the sense of being somehow caried for by another being. "
Many people in the study spoke about how their pets just seemed to "know" when they weren't feeling well and they'd move to get physically near them. Different pets were better at providing comfort, some participants insisted Many said cats were more relaxing companions than dogs, while others said dogs could be relaxing as long as they were “the right kind of dog”. But almost all pets provided some sort of comfort to their owners when it came to touch.
Janette Young, lecturer in health sciences at the University of South Australia, and her team uncovered an interesting thing about the pet-human relationship. People in the study often spoke about how their animals demanded to be petted or seemed to take joy in the interaction. This, in turn, made the humans feel good.
The researchers suggest that pets can be "helpful in reducing touch deprivation（匮乏）” and the benefits can come from all kinds of pets. This connection can be particularly important in health care and senior care settings where patients and workers are less likely to be able to see friends and family； yet touch is important and can improve health and happiness.
Pets can also offer benefits that in some cases people can't offer. "Relationships with pets are different to those with humans,“ Young says. "Animals don't judge and are always with us.” 28. About what did some participants hold different opinions?
A. What pets were better at providing comfort.
B. Whether pets could make them feel relaxed.
C. How they felt when their pets touched them.
D. When pets could notice their owners' discomfort.
29. What did Janette Young find about the pet-human relationship?
A. It is full of judgments.
B. It turns out temporary.
C. It benefits both parties.
D. It is determined by pets.
30. What may researchers suggest hospitals do?
A. Encourage pet connection programs.
B. Raise pets to reduce human touch.
C. Select out the best pet companions.
D. Order workers' friends to pay visits.
31. What is the main idea of the text?
A. Humans need spiritual support.
B. Pet-human interactions are common.
C. Lonely people like living with pets.
D. Pets offer humans touch-based comfort.

There are so many choices when you go shopping. You have to check the sell — by dates so that you know how long you can store and use the food you are purchasing.
But do you know that the best sell — by dates on food packaging don't really tell you if the food is safe to eat. The food may not last as long as it says if it isn't stored correctly at any point of the distribution chain. Now there is food packaging that can detect and change colors if the food has gone bad.
Each American wastes 103 pounds of spoiled food out of the refrigerator every year. The new smart packaging from Primitives Biodesign—a new company that operates out of a lab at Indibio, a biotech accelerator in San Francisco-can help to reduce this huge waste of food.
The basic material that doesn't contain sensing material is made from algae（藻类）and can block oxygen more effectively than regular film, so the food stays fresher for a longer time. Since it is made from a natural substance, it can also break down in nature.
Making the film smart is the thorny part. Luckily, the team managed to use a process that is like the way nature responds to changes in the environment. The mechanism responds like the way flowers emit compounds（排放化合物）to change colors.
“It could be supplement packaging that indicate when it's been tampered with（胡乱摆弄）by changing color to tell you that it's no ledger safe," says Kan. She explained that the new packaging can be used on food products to fell if the food has turned bad before someone has to smell or taste it.
The company has proven in lab tests that the technology works and now they are working on how to develop commercial uses for it. The added safety features will come out later. Helping to control food waste in products like meat or cheese which have high greenhouse gas emissions will also help to reduce climate change.
32. What can we infer from paragraph 2?
A. Storing food properly is very important.
B. The color of food packaging is not clear.
C. Regular food packaging is of little value.
D. It's not hard to control distribution chains.
33. What does the word “thorny” underlined in paragraph 5 probably mean?
A. Changeable.
B. Interesting.
C. Natural.
D. Difficult.
34. What can we say about the new food packaging?
A. It is too thin to block oxygen.
B. It is really good for the environment.
C. It is perfect for commercial uses.
D. It is sensitive to pleasant smells.
35. Which of the following can be the best title for the text?
A. Smart Packaging Tells If Food Is Safe to Eat
B. Sensing Materials Indicate the Color of Food
C. A Great Team Is Concerned With Food Safety
D. Old Packaging Slows Down Climate Change

历年高考英语试卷英语试卷分析
。。 . . 。。. . 2005～2006学年上期期末考试 高一英语试卷分析 雅安市教科所英语组 本次高一英语考试题满分为150分，试题难易适度。但是，从全市高一6780多名学生的答题情况来看，却不容乐观。全市高一英语平均分仅为66.45分，得分率仅为0.44，最高分134分，最低分6分，差异系数33.49。这些数据基本反映出我市高一英语教学质量的现状。这些数据表明我市高一英语教学质量不高，在全省处于落后位置，形势非常严峻，须引起全市高一英语教师高度注意。为此，我们必须认真总结经验，找出差距，认真分析存在的问题，采取措施，改进教学方法，为提高英语教学质量而努力工作。 为了帮助高一英语老师搞好教学工作，我们对试题进行了统计分析(请见统计表)，并将我们的意见简述如下：
本试卷分为听力测试、单项填空、完形填空、阅读理解、写作五道大题，下面分大题进行逐题分析与探讨，并结合教学提出建议。 一、听力测试。该试题以考查对于口头语言的理解为目的，要求学生能够听懂日常交际中发音清楚、语速正常的简短对话和独白。本题满分30分，全市平均分19.57，最高分30分，最低分0分。本题是全卷中难度最低的题，难度系数为0.65。本题也是学生得分最高的题，说明学生的听力有所提高。 本题虽是学生得分最高的题，但是老师和同学们对此决不能骄傲自满。须知，本试题的难度距高考试题尚有一定的差距。在今后的教学中，教师应指导学生多听地道的标准的英美人的录音材料，在教学中应尽量用英语组织教学，鼓励学生在课堂内外大胆地主动地朗读英语，用英语进行对话，不断地提高学生们的听力水平。 二、单项填空。本试题主要考查学生对英语语法、词汇知识和较为简单的表达方式的掌握情况。本题满分25分，全市平均分11.54，最高分25分，最低分0分，难度系数为0.46。学生得分较低。 本题学生得分较低，说明不少的学生在基本的语法掌握上还有差距。本试题既注重考查语言形式，也注重考查语义内容，还注重考查语言的运用。学生得分低，说明学生在语言的运用上还存在较大的差距。 在今后的教学中，教师要指导学生掌握基本的英语语法知识、词汇知识和较为简单的表达方式，还要在此基础上培养学生在特定的语言环境中运用语言的能力。 三、完形填空。本试题主要考查学生在阅读理解的基础上对词汇知识的掌握情况，本题满分30分，全市平均分12.51分，最

广州市2020年高三第二次模拟考试英语试题及答案
广州市2020年高三第二次模拟考试 英语 第二部分阅读理解(共两节，满分40分) 第一节(共15小题；每小题2分，满分30分) 阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。 WENQIANG A We can all think of times when people didn't make remembering easy. Directions given at machine-gun speed. New people introduced in a flood of names and handshakes. Whenever information is passed between people, it’s all too easy for it to go in one ear and straight out of the other. Thankfully, the opposite is also true. Look around you, and you’ll see parents who can get their children to rem ember exactly what they were told; advertisers who know how to imprint their sales messages on our brains. So, how do they do? Their secrets can be summed up in four simple words: focus, imagery, reasons and engagement. FOCUS means ensuring that the person you’re talking to can concentrate on learning. Choose your moment carefully. Check that they can properly hear or see the information. Communicate slowly and clearly enough for their memory to cope. IMAGERY helps information to stick. Do everything your can to make other people “see”the ideas you’re giving them. Add visual details to directions, and illustrate abstract concepts with metaphors. REASONS to remember help people to put in the mental effort. So, make it clear that your words are important, and be explicit about why. Maybe this information will save them time, protectthem from embarrassment, or let them enjoy a particular experience or event. EMGAGEMENT requires you to ask questions. Point out links between new concepts and things listeners already know. Activate their senses, spark their curiosity, get them doing something physical, or simply make them laugh. The next time you’ve got an important message to pass on, put some of these techniques to the test. You’ll discover that there are benefits on both sides when you know how to FIRE people’s memories into action. 21. What is the main purpose of the text? A.To report new research. B.To provide some advice. C.To explain a problem. D.To define some terms. 22. How can you do to help a listener “focus” on w hat you are saying? A.Select the appropriate time to raise the topic. B.Do something humorous to get their attention. C.Make sure the information provided is correct.
2018年高考英语全国卷一试卷分析与历年真题对比及2019备考指南
2018年高考英语全国卷一试卷分析与历年真题对比 一、2018新课标一高考英语考试范围及考试结构 2018年高考英语科目从考试要求、考试形式和卷面结构来看均与2017年保持一致。 【第一部分：听力】20个单选题的形式，听力话题与生活息息相关。 【第二部分：阅读理解】 2018年针对阅读依然是传统的四篇单选阅读加一篇七选五任务型阅读，重点考察考生对文章内容的细节理解、推力判断、词义猜测、主旨归纳以及文章逻辑的处理能力。 【第三部分：语言知识运用】 第一节：完形填空取材于现实，题材为记叙文。通过记叙的方式文章讲述了作者在大学期间学习下棋的经历。这个话题与2017年在大学期间学习手语的话题非常相似。 第二节：语法填空通过提示词和无提示词两种方式着重考察考生对实词和虚词的综合考察。 【第四部分：写作】 第一节：短文改错延续8:1:1的改错原则，8个改词，1个多词，1个缺词。考察重点和方式与往年区别不大。 第二节：书面表达整体中等难度，以邮件的形式介绍去中国朋友家做客的一些习俗。是传统的书信形式，难度不大。 二、2018年新课标高考英语试题命题特点 2018年英语试题，本次题目创新上比较少，整体中规中矩，没有出现偏难偏怪的题目，选项基本上平时强化练习都会涉及到。书面表达也比较容易，作答时不会出现太费力的地方。并且阅读题中设置的难点区分度并不是特别明显。因此整体上来说今年全国卷I英语整体难度较去年略有下降，但个别题目较新颖，考察灵活有设置适量陷阱。 三、2014-2018年新课标高考英语高考点分布及对比分析
四、2019备考指南 1.语法知识的梳理要更加全面，侧重学生对语法知识的基本理解和灵活应用。语法知识的学习不能孤立起来，要跟各个题型的应用相结合。以定语从句为例，要掌握定语从句的基本知识点，明确在短文改错、语法填空中的考查方式；掌握阅读理解中定语从句相关的长难句分析；掌握写作中定语从句句式的灵活应用，以提高写作层次。这样语法知识的学习才能更加全面，真正理解，达到语法知识学习的根本目的。 2.词汇的学习是英语成绩提升的根本，所以要重视词汇的学习和积累。高中单词很多，要分层次的学习。重点单词要会读，会写而且掌握基本的用法及词性转换。非重点单词在阅读理解里面出现不影响理解就可以。掌握各个题型如听力、阅读、完形中的高频词汇，能提高单词学习的效率。 3.各个题型都有一定的做题方法，但最根本的还是词汇和语法知识的灵活应用，所以题型做题方法与技巧的讲解不能脱离具体题目的练习，否则学生不会掌握到任何实质性的方法和技巧。 另外，要在各个题型的讲解中，强化长难句分析的练习，通过阅读理解专项练习进行词汇的积累和文章中长难句的分析，锻炼学生在长难句中提炼关键信息的能力。 4.写作的练习要从最基础的句式开始练习，教给学生独立写句子的能力，单纯的万能句式并不能帮助学生应付所有类型的写作，所以能力的提升才是根本。另外，写作的内容越来越灵活，书信形式基本不变，但是内容上越来越多样化，甚至是倾向于结合相应的文化知识进行写作，所以需要让学生接触更多的写作形式，掌握必要的不同文化背景下的基础词汇。

2017年高考英语试卷分析
高三英语组高考试卷学习总结 李斐 1. 试卷总述 1) 试卷整体难度有所增加； 关于整张英语试卷，我们从三个角度来为大家进行解析和评述。整张试卷从整体上来看，与2016年的高考[微博]相比在难度上有所增加，主要体现在以下几个方面：1. 词汇要求提升；今年的文章词汇难度较2016年有明显的提升，主要体现在阅读理解的文章及选项方面。2. 题目设置难度增加；主要体现在阅读理解部分，与前几年的试题对比，我们会发现今年的试题中出现了多道题目来考查学生对于作者的文章态度的把握能力，比如阅读理解的第24题与31题；同时，对于很多同学而言，完形填空的文章主旨在把握的时候，其实也是会有不小的难度的。3. 考查的知识点范围扩大；从语法填空与短文改错部分来看，知识点的考查范围与去年相比范围有所扩大，同时，也考查到了一些同学们在平常备考过程中比较容易遗忘和疏忽的知识点，比如语法填空的第70题，短文改错的第74题。 2) 考查重点保持不变； 虽然今年的题目在难度上有所增加，但是，考查的重点与往年相比基本变化不大，而这样趋于稳定的命题思路其实也是未来高考的发展趋势。例如，在阅读理解的文体特征上，今年高考仍然延续了前几年的命题趋势，1篇应用文，1篇记叙文以及2篇说明文，并且从文章的排列顺序上来看与往年也基本一致。在完形填空中，我们会发现有不少的题目是需要通过文章的主旨来进行解题的，而这也是我们在考前不断梳理和强调的解题思路。此外，在语法填空部分以及短文改错部分，动词的时态语态、非谓语动词、名词的单数复数以及不同词性之间的词形转换仍然是我们考查的重点。最后，从书面表达部分来看，今年的作文其实是一种对于以往写作场景的回归。在去年进行了写作场景的创新之后，今年又回归到了书信作文中的邀请类作文上面来，应该说也是代表着未来出题的一种趋势，那就是回归到高考题的经典考法上来。 2. 试卷各个题型点评 1)阅读理解与七选五； 阅读理解从文体上来看，与前几年的出题思路一致；但是，在选项设置上与去年相比难度有较大提升，这就对于2017届考生的词汇水平有了较高的要求；同时，2017届考生还要注意对于文章主旨的考查将会成为未来高考考查的重点，需要在平常的备考过程中引起重视。而对于今年的七选五来说，除了第70题以外，其他题目都较为简单，基本不会对大家的解题造成任何的困扰。 2)完形填空
