Fun is hard to have.
Fun is a rare jewel．
Somewhere along the line people got the modern idea that fun was there for the asking, that people deserved fun, that if we didn't have a little fun every day, we would turn into puritans（清教徒）．
“Was it fun?” became the question that overshadowed all other questions. When the pleasure got to be the main thing, the fun fetish（迷恋）was sure to follow. Everything was supposed to be fun. If it wasn't fun, then we were going to make it fun, or else.
Think of all the things that got the reputation of being fun. Family outings were supposed to be fun. Education was supposed to be fun. Work was supposed to be fun. Walt Disney, church and staying fit were supposed to be fun.
Fun got to be such a big thing that everybody started to look for more and more thrilling
ways to supply it. One way was to step up the level of danger So that you could be sure that, no matter what, you would manage to have a little fun.
Big occasions were supposed to be fun, such as Christmas, Thanksgiving and Easter. But we ended up going through every Big Event we ever celebrated, waiting for the fun to start. So I should tell you just in case you're worried about your fun capacity while you are sitting around waiting for the fun to start, that not much is. I don't mean to put a damper on things. I just mean we ought to treat fun reverently. It is a mystery. It cannot be caught like a virus. It cannot be trapped like an animal. When fun comes in on little dancing feet, we probably won't be expecting it. In fact, I bet it comes when we're doing our duty, our job.
I remember one day, long ago, on which I had an especially good time. Pam Davis and I, aged 12, walked into a store that morning to buy some candy. She got her Bit-O-Honey. I got my malted milk balls, chocolate stars. Then we started back to her house. It was a long way to Pam's house but every time we got weary, Pam would put her hand over her eyes, scan the horizon like a sailor and say, "We ought to reach home by nightfall," at which point the two of us would laugh until we thought we couldn't stand it another minute. Then after we got calm, she'd say it again. You should have been there. It was the kind of day and friendship and occasion that made me deeply regretful that I had to grow up.
It is fun.
1．What does the author mainly want to talk about in this passage?
A．The best way to find fun.
B．The importance of fun.
C．The definition of fun.
D．The common occasions to find fun.
2．When the author tells us to "treat fun reverently", she is encouraging us to .
A．look forward to having fun
B．have fun less frequently
C．show great respect for fun
D．teach others how to have fun
3．Who would benefit most from the article?
A．Those who have great fun in big occasions.
B．Those who prefer friendship to having fun.
C．Those who regret having grown up.
D．Those who are worried about not having fun.
B
Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can't talk, but can they lie in other ways? Can they lie with their bodies and behavior? Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive.
Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator (猎食动物) gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the "hurt" adult, leaving the baby birds safe in the nest.
Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.
Birds called cuckoos have found a way to have babies without doing much work. How? They don't make nests. Instead, they get into other birds' nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.
Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner's hand and start fighting again.
Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don't hear them, and they don't need to share their food.
As children, many of us learn the saying "You can't fool Mother Nature." But maybe you can't trust her, either.
4．A plover protects its young from a predator by .
A．getting closer to its young B．pretending to be injured
C．leaving its young in another nest D．driving away the adult predator
5．By "Chimpanzees, or chimps, can also be sneaky" (paragraph 5), the author means .
A．chimps are ready to attack others B．chimps are jealous of the winners
C．chimps are sometimes dishonest D．chimps can be selfish too
6．Which of the following is true according to the passage?
A．Some clever scrub jays often steal their food back.
B．The losing chimp won the fight by taking the winner's hand.
C．Cuckoos fool their adoptive parents by making no nests.
D．Some chimps lower their cry to keep food away from others.
7．Which of the following might be the best title of the passage?
A．Do animals lie?
B．Does Mother Nature fool animals?
C．How do animals learn to lie?
D．How does honesty help animals survive?
C
In the animal kingdom, weakness can bring about aggression in other animal. This sometimes happens with humans also. But I have found that my weakness brings out the kindness in people. I see it every day when people hold doors for me, pour cream into my coffee, or help me to put on my coat. And I have discovered that it makes them happy.
From my wheelchair experience, I see the best in people, but sometimes I feel sad because those who appear independent miss the kindness I see daily. They don't get to see this soft side of others often; we try every way possible to avoid showing our weakness, which includes a lot of pretending. But only when we stop pretending we're brave or strong do we allow people to show the kindness that's in them.
Last month, when I was driving home on a busy highway, I began to feel unwell and drove more slowly than usual. People behind me began to get impatient and angry, with some speeding up alongside me, horning（按喇叭）or even shouting at me. At the moment I decided to do something I had never done in twenty-four years of driving. I put on the car flashlights and drove on at a really low speed.
No more angry shouts and no more horns!
When I put on my flashlights, I was saying to other drivers, "I have a problem here. I am weak and doing the best I can." And everyone understood. Several times, I saw drivers who wanted to pass. They couldn't get around me because of the stream of passing traffic. But instead of getting impatient and angry, they waited, knowing the driver in front of them was in some way weak.
Sometimes situations call for us to act strong and brave even when we don't feel that way. But those are few and far between. More often, it would be better if we don't pretend we feel strong when we feel weak or pretend that we are brave when we are scared.
8．The author feels sad sometimes because . .
A．he has a soft heart
B．he relies much on others
C．some people fail to see the kindness in others
D．some people pretend to be kind
9．What did the other drivers do when they saw the flashlights?
A．They waited with patience.
B．They speeded up to pass.
C．They tried their best to help.
D．They put on their flashlights too.
10．In this passage, the author advises us to . .
A．handle problems by ourselves
B．admit our weakness
C．accept help from others
D．show our bravery
11．Which of the following is the best title for the passage?
A．Wheelchair Experience
B．A Driving Experience
C．Weakness and Strength
D．Weakness and Kindness
D
Give yourself a test. Which way is the wind blowing? How many kinds of wildflowers can be seen from your front door? If your awareness is as sharp as it could be, you'll have no trouble answering these questions.
Most of us observed much more as children than we do as adults. A child's day is filled with fascination, newness and wonder. Curiosity gave us all a natural awareness. But distinctions that were sharp to us as children become unclear; we are numb to new stimulation（刺激）, new ideas. Relearning the art of seeing the world around us is quite simple, although it takes practice and requires breaking some bad habits.
The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs. This blocks awareness. One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream. The students began complaining about how cold it would be. We reached the stream, and they unwillingly walked ahead. They were almost knee-deep when they realized it was a hot spring. Later they all admitted they'd felt cold water at first.
Another block to awareness is the obsession（痴迷）many of us have with naming things. I saw bird watchers who spotted a bird, immediately looked it up in field guides, and said, a "ruby-crowned kinglet" and checked it off. They no longer paid attention to the bird and never learned what it was doing.
The pressures of "time" and "destination" are further blocks to awareness. I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark. It seldom occurred to them to wander a bit, to take a moment to see what's around them. I asked them what they'd seen. "Oh, a few birds," they said. They seemed bent on their destinations.
Nature seems to unfold to people who watch and wait. Next time you take a walk, no matter where it is, take in all the sights, sounds and sensations. Wander in this frame of mind and you will open a new dimension to your life.
12．According to Paragraph 2, compared with adults, children are more .
A．anxious to do wonders
B．eager to explore the world around them
C．likely to develop unpleasant habits
D．sensitive to others' feelings
13．What idea does the author convey in Paragraph 3?
A．To stop complaining all the time.
B．To avoid jumping to conclusions.
C．To follow the teacher's advice.
D．To admit mistakes honestly.
14．Why do the hikers take no notice of the surroundings during the journey?
A．The natural beauty isn't attractive to them.
B．They are keen to see rare birds at the destination.
C．The forest in the dark is dangerous for them.
D．They focus on arriving at the camp in time.
15．In the passage, the author intends to tell us we should .
A．open our mind to new things and ideas
B．get rid of some bad habits in our daily life
C．fill our senses to feel the wonders of the world
D．try our best to protect nature

A possible version:
Dear Jack,
How are you?
I'm Li Hua, editor of Guang Ming High School English Weekly. I've heard that you're anxious about the coming sports meeting, which might have some negative influence on your study if they are not balanced well. I'd like to offer you some suggestions.
To begin with, try to improve your efficiency in class. I highly recommend that you get involved, follow your teachers' steps, keep focused and listen attentively. Only in this way, can you reduce some work load after class. What's more, why don't you learn some tips of time management? It's quite common for Senior Three students to have tons of assignments. With effective time management, you're sure to make your time more productive. Finally, I do think it a good idea to have some sports training after school. On the one hand, you are able to make some preparations for the sports meeting and fight for the glory of your class. On the other hand, you may get some relaxation after a long day work and take your mind off study for a while.
I really hope these suggestions can be of some help. Wish you good luck in the coming sports meeting. May you have a sweet and unforgettable sports meeting.
Yours truly,
Li Hua

广东省实验中学2018届高三上学期第一阶段测试 广东省实验中学2018届高三上学期第一阶段测试 第卷（阅读题共70分） 一、现代文阅读（35分） （一）论述类文本阅读（9分） 阅读下面的文字，完成1-3题。 古代中国很早就建立了一支庞大的官僚队伍。 中国历史上一个鲜明的规律就是，历代官员的数量呈不断扩张趋势。明代刘体健称历代官数，汉七千八百员，唐万八千员，宋极冗至三万四千员。到了明代，文武官员共十二万余人。 官僚系统的不断扩张，是皇权专制制度不断强化的结果。官权是皇权的延伸，君主专制不断完善，注定官僚系统也不断延伸膨胀。秦汉以后，中央集权不断发生强化，官员的权力被不断分割，以期官员相互制衡，弱化他们对皇权的挑战。由此造成一官多职的现象，官僚队伍进一步扩大。 中国传统社会经济结构非常单一，传统赋税又主要只有农业税一途，官员数量的不断膨胀，使得俸禄成为财政支出的第一大项。比如西汉末年，国家赋税收入一岁为四十余万石，吏俸用其半，官员俸禄支出占国家财政收入的一半。所以支付官俸成为财政第一大难题，为了节省开支，薄俸制就成为大多数时候不得已的选择。特别是在皇权专制达于极致的明清两朝，官员薪俸之低也达到惊人的程度。 低俸制的另一个原因是皇权专制的自私短视本性。皇权专制本身是一项不合理的制度安排，它的设计原理是千方百计保证君主的利益，损害其他社会阶层的利益，这其中就包括官僚阶层的利益。在君主专制制度下，皇帝好比一个公司的老总，百官好比员工。压低员工工资，保证自己的利润，对老板来说是一种本能的偏好。从皇帝的视角看来，采取薄俸制和低饷制，用教育来要求百官清廉，既省心省力，又为国家节省了大量财政经费。 传统社会的低俸制，到底低到什么程度？以明代的县令收入为例。明代正七品县令月俸只有七石五斗。用七石五斗粮食养活一个大家庭甚至家族，这个县令的生活只能是普通市民水平。而且明代对于官员办公费用不予考虑，师爷、账房、跟随、门房和稿签等手下均需要县令来养活。再比如曾国藩在做翰林院检讨时，年收入为129两左右，年支出为608两左右。赤字480两左右，需要自己想办法弥补。这是当时京官的常态。 低薪薄俸为朝廷节省了大量的财政支出，也有利于培育出一批清官楷模。但与此同时，薄俸制也有着巨大的危害：它容易诱发腐败，并导致腐败的普遍化。权力笼罩一切，权力不受约束。与此同时，官员们却又只能拿到极低的甚至不能满足基本生活需要的薪水。这就形成了渴马守水，饿犬护肉的局面：让一条饥饿的狗去看着一块肥肉，那么无论你怎么打它，骂它，教育它，它也还是要偷吃，因为不偷吃它就活不下去。在低薪制下，选择做清官的毕竟只是少数，多数官员们不得不想办法搞一些灰色收入，这样贪污就无法根治。对最高统治者来说，这是占小便宜吃大亏之举，因为腐败最后给国家造成的经济损失比开足工资要大得多。 （摘编自张宏杰《顽疾：中国历史上的腐败与反腐败》） 1．下列关于原文内容的表述，不正确的一项是 A．古代中国官员的数量随朝代更迭不断增加，在中国历史上是一个不争的事实。 B．秦汉以后，皇权专制不断细化分割官员权力，目的在于减少官员对皇权的影响。
