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

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

III. Reading Comprehension Section B Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read. B Kettlebells do not hurt people. People do. A kettlebell will get your respect – the easy way or the hard way. Here is the easy way. 1. Get a medical clearance. Get clearance, especially from an orthopedist and a cardiologist. The latter is no joking matter, since kettlebell training can be extremely intense. 2. Always be aware of your surroundings. Find a training area with a non-slippery surface on which you are not afraid to drop a kettlebell. The area must be clear of objects you might trip over – including other kettlebells – or that you might hit with a kettlebell. There should be no people or animals in a radius where you could injure them. 3. Train barefoot or wear shoes with a flat, thin sole and room for the toes to spread. Training barefoot is superior for health and performance reasons. If you must wear shoes, wear Converse Chuck Taylors, Vibram Five Fingers, or similar shoes that have thin soles and do not pinch the toes together. You have sensory receptors on the bottoms of your feet that make you stronger and improve balance and coordination. Wearing traditional shoes diminishes the ability of these receptors to work properly, and therefore inhibits performance and can increase the risk of injury. Go native. 4. Never contest for space with a kettlebell. Do not try to save a rep that has gone wrong. Guide the kettlebell to fall harmlessly, and move out of the way if necessary. And remember, quick feet are happy feet. 5. Practice all safety measures at all times. Respect every kettlebell, even the lightest one. Always use perfect form picking up and setting down a kettlebell. The set is not over until the bell is safely parked.
