高考七选五Lead-in(6mins)Is Fresh Air Really Good for You?We all grew up hearing people tell us to "go out and get some fresh air". 36 According to recent studies, the answer is a big YES, if the air quality in your camping area is good.37 If the air you’re breathing is clean —which it would be if you’re away from the smog of cities —then the air is filled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles(肌肉)and your brain.Recently, people have begun studying the connection between the natural world and healing (治愈). 38 In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood(情绪). Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. 39 It gives us a great feeling of peace.40 While the sun’s rays can age and harm our skin, they also give us beneficial Vitamin D. To make sure you get enough Vitamin D —but still protect your skin —put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that’s plenty of time for your skin to absorb a day’s worth of Vitamin D.(2019全国一)A. Fresh air cleans our lungs.B. So what are you waiting for?C. Being in nature refreshes us.D. Another side benefit of getting fresh air is sunlight.E. But is fresh air really as good for you as your mother always said?F.

It has often been said that there are few new ideas in the world, only reorganized ideas.E. If you are wondering what this has to do with your public speaking class, the answer is quite a lot.F. The skills you learn in your speech class can help you become a more effective thinker in a number of ways.G. As you study the role of evidence and reasoning in speechmaking ,you will see how they can be used in other forms of communication as well.Passage 6Life Story of Dave ThomasSince 1989.Dave Thomas,who died of cancer at age 69 in his Fort Lauderdale home, was one of the most recognizable faces on TV. 1 “As long as it works,” he said in 1991, “ I’ll continue to do those commercials.”2 “He still won’t let anyone see his feet,which are out of shape because he never had proper-fitting shoes,” Wendy said in 1993.Born to a single mother,he was adopted as a baby by Rex and Auleva Thomas of Kalamazoo in Michigan.After Auleva died when he was 5, Thomas spentyears on the road as Rex traveled around seeking construction work.“He fed me,” Thomas said, “and if I got out of line.He’d beat me. ”Moving out on his own at 15,Thomas worked, first as a waiter,in many restaurants. 3 “I thought if I owned a restaurant,” he said, “I could eat for free.” A 1956 meeting with Harland Sanders led Thomas to a career as a Kentucky Fried Chicken restaurant owner that made him a millionaire in 1968.In 1969, after breaking with Sanders,Thomas started the first Wendy’s old Fashioned Hamburgers, in Columbus, Ohio,which set itself apart by serving made-to-order burgers 4 .Although troubled by his own experience with adoption,Thomas,married since 1954 to Lorraine.66.and with four grown kids besides Wendy,felt it could offer a future for other children. He started the Dave Thomas Foundation(基金会)for Adoption in 1992.In 1993,Thomas,who had left school at 15,graduated from Coconut Creek High School in Florida. 5 The kids voted him Most Likely toSucceed.“The Dave you saw on TV,” says friend Pat Williams,senior vice president of the Orlando Magic, “was the real Dave.He wasn’t a great actor or a great speaker. He was just Joe Everybody.”A.But he had something much better in mind.B.He even took Lorraine to the graduation dance party.C.Even though he was successful,Thomas remained troubled by his childhood.D.By using his experience and determination,Thomas turned the restaurants around.E.With 6,000 restaurants worldwide,the chain now makes $6 billion a year in sales.F.He appeared in more than 800 commercials for the hamburger chain named for his daughter,now 40.G.He dropped out of school to work full-time.This decision to drop out haunted him until he went back to school 45 years later.Passage 7As is known to all, many things can be measured in terms of data. Sometimes data can indeed tell the truth. With the help of data we can easily know the price of a can of Coke in the supermarket or the result of a football match. 71 What is more important, data seem to be fairer than words or statements. If the data are true, we don’t have to worry about being cheated. Nowadays, as lies exist in the world, data are expected to tell the truth. Therefore, many of us would rather believe data.On the other hand, if we judge things only by data from the so-called specific research, aren’t we a little too narrow-minded? Many people often treat the so-called specific data unwisely just to make sure that they are making the right decisions. 72 For example, how can you tell that somebody isn’t a good student just because he or she doesn’t get high marks in the final examination?73 For example, the degree of your feeling happy in your life, the depth of love between you and your friends, and the faith you have inyour country. We can only feel them in our hearts but can never express them in data.There is no doubt that analyzing the exact data is important to assessment of an actual event. But data should be dealt with wisely. We often get wrong data which mislead us. 74 Remember, data have no feeling but we humans have. Data do not mean much to people if we do not have the abilities to analyze the data with the knowledge and confidence to judge whether they are true or false. 75Data are data after all. Life is much more colourful than the pale data. So give the cold data a warm heart and we’ll find that the world is far more wonderful than the pale data can describe.A. We should try our best to be wise thinkers.B. Data can make our life easier and more comfortable.C. But sometimes we may find that data aren’t everything.D. Sometimes our hearts and mind are more sensitive than data.E. Now and then the so-called specific data puzzle us very much.F. The exact data should come from assessment of an actual event.G. There are many things in our life which cannot be measured by data.1.(Key: AECDB). G 72. E 73. A 74. F 75. C3. 71. G 72. E 73. A 74. F 75. C. C 72. B 73. G 74. D75. A5.DEAFG:1. F 4. E —75 BCGDA。
专项练习——高考阅读7选5【小试牛刀】根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项。
MuzakThe next time you go into a bank, a store, or a supermarket, stop and listen. What do you hear? 71 It’s similar to the music you listen to, but it's not exactly the same。
That’s because this music was especially designed to relax you,or to give you extra energy. Sometimes you don’t evenrealize the music is playing, but you react to the music anyway。
Quiet background music used to be called "elevator (电梯) music" because we often heard it in elevators。
But lately we hear it in more and more places, and it has a new name "Muzak"。
About one—third of the people in America listen to ”Muzak” everyday. The music plays for 15 minutes at a time, with short pauses in between. It is always more lively between ten and eleven in the morning, and between three and four in the afternoon, when people are more tired. 72If you listen to Muzak carefully, you will probably recognize the names of many of the songs。
高考七选五复习知识精讲高考的7选5题型,它要求考生在一段留有5个空白的约300词的短文中个,根据文章结构、内容,从所给的7个选项中选出最佳答案,填入相应的空白处,使补全后的短文意思通顺、前后连贯。
这种题型突出考查语篇结构分析能力,属于对语言使用范畴及语言组织规律的考查,即对文章结构以及整体内容和结构以及上下文逻辑意义的理解和掌握。
具体答题步骤如下:步骤一:快速浏览一遍七个备选答案,先确定哪个选项适合放在文章的什么位置。
通常有三个四个位置:标题,句首,句中,句尾。
不同位置的句子有不同的特征。
有时有的答案表述上就是错误的,可以直接从备选项中清除,以降低难度。
步骤二:快速浏览文章,确定文章体裁,抓住文章结构。
不同的文章有不同的结构形式,确定文章体裁有利于我们确定各段之间的关系。
一般说来,记叙文的语言是按时间发展顺序或因果关系排列的,常用的连接词有:then, later, after that, soon, after a while, in the end, so, as a result, because of等。
说明文常采用“总—分—总”的结构形式,第一段说明要说明的主题,下面几段多是从不同的角度来说明问题,最后总结,所以各段之间多是平行关系,经常出现举例说明的现象。
议论文先抛出议题,然后从正反两个方面进行讨论,最后得出结论。
新闻体裁的应用文首句为主题句,下面展开细节性的报道。
确定文章体裁有利于预测文章各段主要内容和结构形式,形成重要的选择依据步骤三:分析篇章结构,找出各段的主题句或主旨大意。
分析文章的层次包含两种形式:一种是分析整篇文章的层次,也就是段落,说明文和议论文这样体裁的文章,每段的第一句多是主题句找到主题句有助于帮助确定选择的范围,即所选句子必须和该段主题一致。
另一种是分析每一个段落内部的层次,也就是语篇层次。
要真正体会句际间的意义关系,把握作者的思路,从语序上去发现断续点,理清层次步骤四:注意各选项中出现的句子衔接手段,寻找句中衔接标志词。

51 You don't show your secret personality when you are awake because you can control your behavior, but when you are asleep, your sleeping position shows the real you. 52 The important position is the one that you go to sleep in.If you go to sleep on your back, you're a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don't like to displease people. So you never express your real feelings. 53If you sleep on your stomach, you are a rather secretive person. You worry a lot and you're always easily upset. You always stick to your own opinions or judgment, but you aren't very ambitious.54 .This means that you enjoy having a good time.If you sleep curled up, you are probably a very nervous person. You have a low opinion of yourself and so you're often delusive. You're shy and you don't normally like meeting people. You prefer to on your own, You're easily hurt.If you sleep on your side. yon have usually got a well—balanced personality. 55. You're usually careful. You believe in yourself. You sometimes feel anxious, but you don't often get sad. You always say what you think even if it makes people rather angry.A. You're quite shy and you aren't quite sure of yourself.B.

期末考试专题阅读理解7选5串讲及精练(学生版)-2022-2023学年高一英语期末考点大串讲人教版阅读理解、7选5串讲及精练一.细节理解题根据题干中的关键词,回到原文定位信息区间,稍加比对,就能得出正确答案。
因此,对于这类题目要力求读得快、找得准、答得对,力争不丢分,保住基本分才能得高分。
但有些细节理解题由于命题人故意设置障碍,把有用信息分散在文章不同位置,有时又有转折、否定等,因此有些题目需要仔细地思考、对比、计算、对上下文关键信息把握和分析。
尽管细节理解题相对简单,但不可掉以轻心。
细节理解题常见的考查题型有:直接信息题、间接信息题、概括细节理解题和正误判断题。
二.猜测词义题根据上下文猜测词义是阅读能力的一部分,也是高考阅读理解测试中重要的一项。
要做好这类题目,考生要记住:在完整的语篇中,单词和词组的意义总是受特定的语境、上下文限制的,因此考生可以根据上下文,并利用所掌握的语法、词汇和构词法等知识确定它们的意义。
词义猜测可以是对一个单词的意义的推断,也可以是对一个短语或句子的意义的推断;既可以考查生词的意义,也可以考查熟词的新义,还可以是对替代词所替代内容的判断。
在阅读理解题中,所考查的词或短语的意义往往不停留在字面上,而要根据短文提供的语境,通过阅读上下文,根据已知的信息或常识来推测尚不熟悉的词或短语的含义。
By saying that “...” in the first (second ...) paragraph, the author means that ______ __.In Paragraph ..., “...” can be replaced by “______”.The meaning of “...” in Paragraph ... is re lated to ________.Which of the following has the closest me aning to ... (Paragraph ...)?As is used in Line ..., the word “...” refers to ________.The underlined sentence in the ... paragra ph probably means that ________.三.推理判断题解答该类型题目时一定要从整体上把握语篇内容,在语篇的表面意义与隐含意义、已知信息与未知信息之间架起桥梁,透过字里行间,去体会作者的“弦外之音”和“言外之意”。

This response is triggered by the five senses, which are always sending information to the brain. 7., the brain sounds adanger alarm. It releases chemicals into the bloodstream, and those chemicals act on different parts of the body. Once the body is alert(警觉的),the brain decides whether or not the danger is real.8.It urges a person to hide, run away, or defend oneself.

Chicken and fish contain less fat than meat and eggs. Many people are also buying more fresh vegetables and eating them raw or cooked quickly in very little water in order to keep vitamins.18.The “typical” North American diet now includes food from many different countries. More restaurants are opening in big cities in the United States and Canada. Foods from China, Japan, Korea, Thailand, India, and the Middle East are very popular. Even fast food places now offer “lean” (low-fat) hamburgers, roasted (instead of fried)chicken, and salad bars with a wide variety of fresh fruits and vegetables.19.Because we now know about the importance of nutrition, we will probably continue to eat more fish and vegetables and less meat. We will still buy convenience foods in supermarkets, but frozen foods may be more nutritious and canned foods may have less salt and sugar. 20.Instead of candy bars we will eat “nutrition bars” with a lot of vitamins and protein.
