What is body surfing?
Bodysurfing is related to riding on a wave with no help from aid tools such as a surfboard. That’s why it is called the “purest” form of surfing. In fact, it is one of very few extreme sports—free climbing and cliff diving are. others—that can be practiced using nothing but the human body.
How do you do it?
To catch a wave, swim to where the waves break and, as one approaches, start swimming towards the beach. You must try to travel at the same speed as the wave and, if you do it correctly, you will feel the wave lifting you and pushing you forwards. Then try and cut along the surface of the wave.
What do you need?
It is more enjoyable and safer if you use flippers (large flat rubber shoes). This is because they enable you to swim faster and surf along them more easily. A wetsuit is also advisable. Another aid is a handboard, a mini-surf board about the size of an iron, held in one hand to speed up along the wave. If you are lucky enough to be surfing in warm water, make sure you have your boardshorts at the ready.
Unofficial world championship
Bodysurfing is not a professional sport, but in Hawaii there is such a festival called the Pipeline Bodysurfing Classic each year. Local bodysurfers compete against athletes from places such as Australia, Brazil, Japan or France. Famous bodyboarder Mike Stewart has won the event no fewer than 12 times, and Kelly Slater, the greatest surfer in history, has also competed.
1. How does a bodysurfer surf while in the sea?
A. Only using the human body. B. Only relying on a surfboard.
C. Only following a wave. D. Only swimming along the beach.
2. Which can make you surf faster?
A. Flippers and a wetsuit. B. A wetsuit and a handboard.
C. A handboard and boardshorts. D. A handboard and Flippers.
3. What can we know about the Pipeline Body surfing Classic?

Recently，as I watched my son Nathan play basketball for his high school team，I was starting to feel sorry for myself and for him．His team was facing adversity（逆境）on the court and he was playing in a hostile environment-it was the opponent’s home gym filled with their supporters，and Nathan’s team was trailing（落后）for three quarters of the game．As for me，I had been dismissed from my job earlier in the day．
During my drive home，I kept telling myself that I will find work again in a short time-I am confident in my experience and abilities．This is the same belief that I tried to instill in my son．
The basketball game entered the fourth quarter with Nathan’s team still trailing．I saw the determination on his，as well as his teammates’faces as they fought back to not only tie the game（平局），but then go ahead by three points．Then，a player from the other team made an unbelievable shot to tie the game up again．With a tie game and seconds on the clock，Nathan found himself with the ball and with skill and confidence，he proceeded to make the basket with a defender hanging all over him．The other player was called for a foul（犯规）．
As Nathan stood at the foul line preparing for a shot that would put his team up by three points，I saw the focus and determination on his face，there was no room for self doubt．Nathan was able to tune out all the distractions and nail the free throw with such skill，it was as if he had done it a thousand times．
As I sat there，my heart bursting with pride，it dawned on me．I had taught him perseverance in the face of adversity，and he had just taught me the same lesson．That brief moment of self-doubt and feeling sorry for myself was blown away by the actions of my son on the basketball court．He will play in the finals，but it doesn’t matter if he wins or loses，at this moment，we both won．

这是一篇记叙文。本文讲述了作者在观看儿子篮球比赛过程中，看到儿子球队在比赛临近尾声并处于劣势的情况下，依然满怀信心、坚持不懈，最后获得了胜利。这番情景让刚刚失业正处于沮丧不自信中的作者消除了自我怀疑，重新燃起了生活的斗志。
【4题详解】
推理判断题。根据文章第一段中的“Recently, as I watched my son Nathan play basketball for his high school team, I was starting to feel sorry for myself and for him. His team was facing adversity on the court and he was playing in a hostile environment-it was the opponent’s home gym filled with their supporters, and Nathan’s team was trailing for three quarters of the game.（最近，当我看到我儿子Nathan为他的高中队打篮球时，我开始为自己和他感到难过。他的球队在球场上正面临着逆境，他在一个充满敌意的环境中打球，对手的主场体育馆里挤满了他们的支持者，Nathan的球队落后了3分比赛的四分之一。）”可知，一开始的时候，作者认为自己儿子所在的球队会失败，结合选项，故选D。
【5题详解】
推理判断题。根据文章第二段中的“During my drive home, I kept telling myself that I will find work again in a short time-I am confident in my experience and abilities. This is the same belief that I tried to instill in my son.（在开车回家的路上，我一直告诉自己，我会在短时间内重新找到工作，我对自己的经验和能力充满信心，这和我试图灌输给儿子的信念是一样的。）”可知，作者对于自己是充满了信心，同时对生活也是积极乐观的态度。结合选项，故选B。
【6题详解】
词义猜测题。“and”前后为两个并列的短语，由短语“nail the free throw with such skill（用这样的技术把罚球钉住）”可知，Nathan能够把所有的分心都解除。故可推知划线单词意为：避免。A. Avoid避免；B. Focus集中注意力；C. Create创造；D. Receive接收。故选A。
【7题详解】
主旨大意题。根据文章内容，本文讲述了作者在观看儿子篮球比赛过程中，看到儿子球队在比赛临近尾声并处于劣势的情况下，依然满怀信心、坚持不懈，最后获得了胜利，这番情景让刚刚失业正处于沮丧不自信中的作者消除了自我怀疑，重新燃起了生活的斗志。所以选项C中的life与作者的生活状况呼应，其中的basketball与作者的孩子的比赛呼应，lesson与作者的体会呼应。故选C。
【点睛】主旨大意题是篇章阅读一个主要的考查方式，最佳标题题（best title）是其一个典型的考点，也是高考阅读中每年的必考题。主旨大意题解题技巧是不要被文章细节所干扰。一般有两种方式解题：一是看首尾段，根据首尾段内容总结主题思想；二是看每段段首句，根据所有段首句总结主题思想。例如本文中的第四题，这是一篇记叙文，根据文体特点可知，记叙文一般会在文章最后点名文章中心，所以由文章最后一段中的“That brief moment of self-doubt and feeling sorry for myself was blown away by the actions of my son on the basketball court. ”可知作者重新燃起了生活的斗志。且选项C中的life与basketball两个关键词都与故事情节紧密相关，故选C。
C
More People Are Leaving the Rat Race for the Simple Life
Time is more precious than money for an increasing number of people who are choosing to live more with less—and liking it.
Kay and Charles Giddens, two lawyers, sold their home to start a B&B hotel. Four years later, the couple dishes out banana pancake breakfast, cleans toilets and serves homemade chocolate chip cookies to guests in a B&B hotel surrounded by trees on a hill known for colorful sunsets.
“Do I miss the freeways? Do I miss the traffic? Do I miss the stress? No,” says Ms. Giddens, “This is a phenomenon that’s fairly widespread. A lot of people are reevaluating their lives and figuring out what they want to do. If their base is being damaged, what’s the payoff?”
Simple living ranges from cutting down on weeknight activities to sharing housing, living closer to work, avoiding shopping malls, borrowing books from the library instead of buying them, and taking a cut in pay to work at a more pleasurable job.
Vicki Robin, a writer, lives on a budget equal to a fifth of what she used to make. “You become conscious about where your money is going and how valuable it is,” Ms. Robin says, “You tend not to use things up. You cook at home rather than eat out…”
Janet Luhrs, a lawyer, quit her job after giving birth and leaving her daughter with a nanny for two weeks. “It was not the way I wanted to raise my kids,” she says, “Simplicity is not just about saving money; it’s about me sitting down every night with my kids to a candlelit dinner with classical music.”
Mrs. Luhrs now edits a magazine, Simple Living, which publishes tips on how to buy recycled furniture and shoes, organize potluck dinners instead of expensive receptions, and generally how to consume less.
“It’s not about poverty,” Mrs. Luhrs explains, “It’s about conscious living and creating the life you want. The less stuff you buy, the less money goes out of the door, and the less money you have to earn.”
8. Kay and Charles Giddens sold their home to ______.
A. pay off the debt
B. start a private hotel
C. cut down expenses
D. buy living necessities
9. Simple living includes ______.
A. building a home library
B. living in the countryside
C. enjoying a colorful night life
D. sharing housing with others
10. It can be learned from the passage that now Janet Luhrs ______.
A. spends more time with her kids
B. has an interest in classical music
C. works as a reporter of a magazine
D. helps people buy recycled clothes
11. How does the author develop the passage?
A. By using figures.
B. By asking questions.
C. By giving examples.
D. By making comparisons.
【答案】8. B 9. D 10. A 11. C
【解析】
本文是一篇说明文。越来越多的人摆脱激烈竞争的环境回归简单的生活。他们重新审视生活的价值，希望过上一种自己喜欢的生活。
【8题详解】
细节理解题。根据文章第二段中的sold their home to start a B&B hotel可知，他们把房子卖掉是为了经营自己的酒店，故选B。
【9题详解】
细节理解题。根据第四段中的Simple living ranges from cutting down on weeknight activities to sharing housing可知，D选项sharing housing with others包含了simple living的内容，故选D。
【10题详解】
推理判断题。根据文章第六段中的It was not the way I wanted to raise my kids,” she says, “Simplicity is not just about saving money可知，Janet Luhrs不工作是因为想把更多的时间花在跟她的小孩子一起，故选A。
【11题详解】
推理判断题。纵观全文，不难看出文章是用了几个人物的例子，如Kay and Charles Giddens夫妇，作家Vicki Robin等，来讲述Simple living的概念的，故选C。
D
The new garbage sorting regulation has taken effect in Shanghai starting from July 1. Many citizens are still confused about the classification of the four different types of trash. Thankfully, authorities have released an official guideline to explain the new rules.
The guideline, published by the Shanghai Greenery and Public Sanitation Bureau, provides a rather clear definition on the four kinds of waste: recyclable waste, harmful waste, household food waste and residual (剩余的) waste.
Harmful waste, as the name suggests, includes various poisonous materials like used batteries, light bulbs, out-of-date medicines, paint and pesticides.
Household food waste — which is translated to “wet trash” in Chinese — refers to food leftovers, rotten food, pet food, fruit peels, remains of TCM herbs (中药) and flowers.
Paper, plastic, glass, metal and textiles (纺织品) are counted as recyclable waste.
The definition of residual waste is a little confusing. Anything that is not listed above belongs to this category.
As specific as the new guideline is, residents still have a hard time sorting trash correctly and are finding it challenging to memorize them all. For instance, both plastic bottles and bubble tea or coffee cups are plastic materials. However, the former falls to the category of recyclable waste and the latter belongs to residual waste. To save the hassle, some netizens have come up with their own way to sort trash.
“We should do this from a pig’s angle,” commented one netizen. “Those edible (可食用的) for pigs are household food waste. Those even pigs don’t want to eat are residual waste. If a pig consumes something and dies of it, then something must be harmful waste. Those that can be sold and the money we gain can be used to purchase pigs are recyclable waste.”
The new regulation came into effect on July 1. Those who do not sort their trash properly will be fined RMB 200.
12. What do the old coats that you want to throw away belong to?
A. Harmful waste. B. Wet trash.
C. Recyclable waste. D. Residual waste.
13. What is the common point of “wet trash”？
A. They can be broken down easily. B. They all come from plants.
C. They all have bad smells. D. They all have poisonous materials.
14. What is the tone of the netizen like?
A. Serious. B. Humorous.
C. Delightful. D. Uncertain.
15. What does the passage mainly talk about?
A. The four sorts of garbage are forbidden in Shanghai.
B. Shanghai garbage sorting enforcement begins.
C. People are still confused about garbage sorting.
D. The netizens in Shanghai support the garbage sorting policy.
【答案】12. C 13. A 14. B 15. B
【解析】
本文是一篇说明文。文章介绍了上海的垃圾分类指南以及相关规定出台后，人们对此作出的反应。
【12题详解】
细节理解题。根据第五段Paper, plastic, glass, metal and textiles (纺织品) are counted as recyclable waste.可知纸、塑料、玻璃、金属和纺织品都是可回收的废物。纺织品属于可回收垃圾，而旧衣服属于纺织品，故选C。
【13题详解】
推理判断题。根据第四段Household food waste — which is translated to “wet trash” in Chinese — refers to food leftovers, rotten food, pet food, fruit peels, remains of TCM herbs (中药) and flowers.可知，家庭食物垃圾——在中文里被翻译成“湿垃圾”——指的是剩饭剩菜、腐烂的食物、宠物食品、果皮、中草药和鲜花的残留物。由此可知，“湿垃圾”的共同点是它们很容易分解。故选A。
【14题详解】
推理判断题。根据倒数第二段中“We should do this from a pig’s angle,” commented one netizen.可知，一位网友评论道：“我们应该从猪的角度来做这件事。”由此可推知，该网民说从猪的角度来看，可见该网民是以一种幽默的语气来表达自己的观点的。故选B。
【15题详解】
主旨大意题。根据第一段中The new garbage sorting regulation has taken effect in Shanghai starting from July 1.可知，新的垃圾分类规定已于7月1日起在上海生效。后文又介绍了上海的垃圾分类规定的出台及具体内容，如可回收垃圾、厨余垃圾、有害垃圾等的具体内容，以及人们对此的反应。故选B。

【解析】
【分析】
这是一篇记叙文。文章介绍了最近在中国四川省竹林里发现了一只野生大熊猫。
【41题详解】
考查名词。句意：在野生大熊猫数量不到2000的情况下，看到一只这种可爱的动物是一件值得庆祝的事情。根据is a cause for可知此处要用名词，且celebration是不可数名词。故填celebration。
【42题详解】
考查非谓语动词。句意：然而，最近在中国四川省竹林里看到的那只大熊猫更是如此，考虑到它是世界上已知的第一只纯白色大熊猫！此处要用现在分词作原因状语。故填considering。
【43题详解】
考查动词的时态和语态。句意：2019年5月25日，监控卧龙国家级自然保护区野生动物的红外摄像机发现了这只熊猫，这里也是中国首个大熊猫繁育和研究中心的所在地。根据on May 25, 2019可知时态是一般过去时，且主语是It，与spot之间是被动关系，因此要用一般过去时的被动语态。故填was spotted。
【44题详解】
考查非限制性定语从句的关系词。句意：2019年5月25日，监控卧龙国家级自然保护区野生动物的红外摄像机发现了这只熊猫，这里也是中国首个大熊猫繁育和研究中心的所在地。分析句子成分可知，此处是一个非限制性定语从句，先行词是Wolong National Nature Reserve，指物，且非限制性定语从句缺少主语，因此要用关系代词which。故填which。
【45题详解】
考查不定式。句意：据卧龙官方估计，这只大熊猫的年龄在1到2岁之间，性别很难从照片上判断。根据is hard可知此处要用不定式，是主动表示被动的用法。故填to determine。
【46题详解】
考查代词。句意：人们普遍认为，大熊猫独特的黑色和白色的颜色使它能够在冬天融入雪中，或在夏天躲在阴凉处。根据is generally believed可知此处要用it作形式主语，真正的主语是that-从句。故填It。
【47题详解】
考查名词的复数形式。句意：一些科学家还认为，熊猫眼睛周围的黑眼圈有助于它们相互识别。根据Some可知此处要用名词的复数形式，且scientist是可数名词。故填scientists。
【48题详解】
考查副词。句意：幸运的是，到目前为止，记号的缺乏似乎并没有影响到这种全白的熊猫。此处要用副词，放在句首，修饰整个句子。故填Luckily。
【49题详解】
考查介词。句意：由于世界上现存的大熊猫标本如此之少，这种情况发生的可能性几乎是不可能的。固定短语in the world“在世界上”。故填in。
【50题详解】
考查形容词。句意：研究人员认为，如果它的后代能够被拍摄下来，将对进一步的研究有价值。根据will be可知此处要用形容词作表语。故填valuable。
【点睛】第5小题考查了be+形容词+to do的用法。在“be+形容词+to do”结构中，通常使用不定式的主动形式表示被动意义。
例1：The cake is easy to make这种蛋糕很容易做。
cake与make之间为逻辑上的被动关系，好像应使用 to be made形式，但事实上使用不定式的主动式。
例2：The apples are hard to reach苹果很难够到。
apples与reach之间为逻辑上的被动关系，但实际上用不定式的主动式。
第四部分写作（共两节，满分35分）

About how to keep healthy, I’d like to offer my advices. As we know, we teenagers are going through a rapid growth which needs to be support by a healthy and balanced diet.

【答案】1advices→advice
2.support→supported
3.out→down
4.However→Besides/Moreover
5.regular→regularly
6.take后添加a
7.Have→Having
8.you→we
9.stayed→stay
10.去掉that
【解析】
【分析】
这是一篇说明文。作者就如何保持健康提供了一些自己的建议。
【详解】1.考查名词。句意：关于如何保持健康，我想提供我的建议。advice为不可数名词，没有复数形式。故advices改为advice。
2.考查非谓语动词。句意：我们知道，我们青少年正在经历一个快速的增长，这需要一个健康和平衡的饮食支持。根据上文need to be done“需要被……”，可知应用过去分词。故support改为supported。
3.考查固定短语。句意：因此，我们需要各种各样的食物，但减少富含糖或脂肪的食物。短语cut out表示“切断”，结合句意此处表示“减少”应用短语cut down。故out改为down。
4.考查副词。句意：此外，我们应该经常锻炼身体。结合句意可知表示“此外，而且”应用连接副词besides或moreover。故However改为Besides/Moreover。
5.考查副词。句意同上。此处修饰动词take应用副词，故regular改为regularly。
6.考查冠词。句意：例如，放学后我们可以打篮球或散步。短语take a walk“散步”，故take后添加a。
7.考查非谓语动词。句意：有足够的睡眠是非常重要的。本句中缺少主语，需要动名词短语having enough sleep做主语，故Have改为Having。
8.考查代词。句意：因此，我们应该每天至少有8个小时的睡眠，不要熬夜太晚。结合句意可知表示“我们”应用代词we。故you改为we。
9.考查动词时态。句意同上。根据上文every day可知应用一般现在时，故stayed改为stay。
10.考查倒装句。句意：只有这样我们才能保持健康。本句为“only+状语/状语从句”位于句首时，句子 主语和谓语或主句中的主语和谓语要部分倒装。故不需要that。故去掉that。
【点睛】当分词做状语的时候，如果构成分词的动词与句子的主语构成主动关系，就使用现在分词做状语；当二者构成被动关系，使用过去分词做状语。如果分词的动作发生在谓语动词之前，就使用分词的完成式。如果分词与句子的主语没有关系，可以使用状语从句或者独立主格结构。如第七小题，本句中缺少主语，需要动名词短语having enough sleep做主语，故Have改为Having。
