While learning the science lessons, I used to get a doubt--why ear, nose, tongue and eyes should be called as special senses? The basic reason is that these are the channels through which we maintain contact with the surroundings. Though apparently it may feel like these are individual sensory organs, they do show some connectivity. Interestingly, our hearing is less sharp after we eat a heavy food. Isn’t it good for a sound nap after a stomach-full meal? That does not mean we go deaf after a meal, but the hearing pitch(强度)does change after a heavy meal.
We usually give credit of the taste to our tongue, but do you know that unless saliva(唾液)dissolves something, our tongue cannot recognize the taste of the food eaten. Taste is nothing but the food chemicals dissolved in the saliva being sensed by the taste buds(味蕾)present on the tongue. Try to dry off your tongue and mouth with a tissue paper and then taste something.
Women are much better smellers than men. They are born with this characteristic ability and can correctly recognize the exact fragrance of the sample. We all can store almost 50,000 different smells, which are strongly tied to the memories.
Pupils(瞳孔)do not respond to light alone, but to the slightest bit of noise around too. Thus surgeons, watchmakers and those professionals who have to perform a much delicate job do prefer to have a sound-free environment. Even a small noise can enlarge their pupils, change the focus and make their vision less clear.
Each and every one of us has a particular or individualistic or characteristic smell, which is unique to us, except the twins. This smell is very subtle yet can be sensed even by a newborn. It may be due to this smell that the newborn recognizes the presence of his parents around.
【小题1】What may happen after you have had a rich lunch?

A.Your eyes become weak and can not see well.
B.You may feel energetic and fresh.
C.Your hearing pitch may be decreased.
D.Your tongue may lose the function of taste.
【小题2】. What does the author mean by the underlined sentence in paragraph 2?
A.Our tongues can’t be dried while eating something.
B.If your tongue is dried without any saliva on it, it will not work.
C.A tissue paper is the only thing that can be used to dry our tongues.
D.If your tongue is dried with a tissue paper, it may work as well as before.
【小题3】What makes each person different from anyone else except twins according to the passage?
A.The number of sensory organs.
B.The functions of sensory organs.
C.The particular smell of a person.
D.The style of one’s behavior.
【小题4】Which of the following may be the best title of this passage?
A.The Sensitivity of Sensory Organs
B.The Functions and Connections of Sensory Organs
C.A Newborn’s Sensory Organs
D.Different Senses Between Men and Woman

A
This is a great truth, one of the greatest truths.
It is a great truth because once we truly see this truth, we transcend(超越) it. Once we truly know that life is difficult--once we truly understand and accept it--then life is no longer difficult. Because once it is accepted, the fact that life is difficult no longer matters.
Most do not fully see this truth. Instead they complain about their problems and difficulties as if life should be easy. It seems to them that difficulties represent a special kind of suffering especially forced upon them or else upon their families, their class, or even their nation.
What makes life difficult is that the process of facing and solving problems is a painful one.  Problems, depending on their nature, cause us sadness, or loneliness or regret or anger or fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy.
Yet, it is in this whole process of solving problems that life has its meaning. Problems are the serious test that tells us success from failure. When we desire to encourage the growth of human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve. It is through the pain of meeting and working out problems that we learn. As Benjamin Franklin said, those things that hurt, instruct. It is for this reason that wise people learn not to fear but to welcome the pain of problems.
【小题1】From the passage, it can be inferred that ______.

A.everybody has problems
B.we become stronger by meeting and solving the problems of life
C.life is difficult because our problems bring us pain
D.people like to complain about their problems
【小题2】 The writer probably used just one short sentence in the first paragraph to ______.
A.save space B.persuade readers

B.the writer feels life is easy
C.the writer likes to complain about his problems
D.most people complain about how hard their lives are

A.encourage them to learn
B.teach them to fear the pain of solving the problem
C.help them learn to deal with pain
D.teach them how to respect from problems
【小题5】The saying from Benjamin Franklin “Those things that hurt, instruct” suggests that ______.

One of my main concerns when I am helping people achieve their goals is how they measure success. I see individuals getting frustrated as they struggle hard for success.
One of the main reasons that cause this frustration is that people allow their definition of success to be determined by someone or something else. Another is that they become frustrated at their own apparent lack of success when comparing themselves to other people.
We are individuals with individual wants, skills and experiences. We should look at our own skills to determine what is successful to us. We should look inwards to determine what it would mean for us to be successful in our own mind rather than someone else’s.
Evaluating a successful person needs to look at his pathway to success, his actions ,his determination and translate that into his own experience to see how he can improve himself.
You must set your own course of action, and stay on your course. You alone must determine what success means to you. Do what you do to the best of your ability and the rest will take care of itself. For example, I believe that I am successful but I am not a millionaire! Others may not see me as successful in their eyes but that does not matter. It is how I see myself that is important to me and my life.
Here is the truth. Being a success is doing your best, not being the best. Success is not something you become; it is something you continue being.
When we get to that point, we will experience a lot more joy and a lot less frustration. And that sounds good to us!
Remember the great quote from Napoleon Hill, “If you cannot do great things, do small things in a great way.”
【小题1】What’s the best title of this passage?

A.Frustration Determines Success
B.The Importance of Frustration to Success

A.struggle too hard B.know little about others
C.are often discouraged D.underestimate themselves
【小题3】Which is NOT true according to the passage?
A.Success is something you keep on being rather than you become.
B.Evaluating a successful person needs to look at others’ judgment.
C.It doesn’t matter others may not consider you as a success in their eyes.
D.It matters that you set your own course of action and stay on it.
【小题4】According to the passage the writer advises us to_____.
A.attach the importance to others’ attitude and evaluation

Attitude is an internal(内在的) state that influences the choices of personal action made by the individual(个人). Some researchers consider that attitudes come from differences between beliefs and ideas; others believe that attitudes come from emotional states. Here, we focus on the effects of attitudes upon behavior, that is, upon the choices of action made by the individual.
The kinds of actions taken by human beings are obviously influenced greatly by attitudes. Whether one listens to classical music or rock, whether one obeys the speed limit while driving, whether one encourages one’s husband or wife to express his or her own ideas-all are influenced by attitudes. These internal states are acquired(获得) throughout life from situations one is faced with in the home, in the streets, and in the school.
Of course, the course of action chosen by an individual in any situation will be largely determined by the particulars of that situation. An individual who has a strong attitude of obeying laws may drive too fast when he is in a hurry and no police cars in sight. A child who has a strong attitude of honesty may steal a penny when she thinks no one will notice. But the internal state which remains unchanged over a period of time, and which makes the individual behave regularly in a variety of situations, is what is meant by an attitude.
Attitudes are learned in a variety of ways. They can result from single events, as when an attitude toward snakes is acquired by an experience in childhood at the sudden movement of a snake. They can result from the individual’s experiences of success and pleasure, as when someone acquires a positive attitude toward doing crossword puzzles by being able to complete some of them. And frequently, they are learned by copying other people’s behavior, as when a child learns how to behave toward foreigners by observing the actions of his parents. Regardless of these differences, there is something in common in the learning and modification(修正) of attitudes.
【小题1】According to the passage, attitudes        .

A.come from different situations in one’s life
B.are largely affected by one’s behavior
C.remain unchanged in one’s daily life
D.could be chosen according to one’s will
【小题2】The author uses the examples in Paragraph 3 to show        .
A.people often make mistakes when they are not noticed
B.people with good attitudes may sometimes do bad deeds
C.particulars of a situation may influence an individual’s action
D.an individual may change his or her attitude fairly easily
【小题3】Which of the following is TRUE about the learning of attitudes?
A.Attitudes are only learned through one’s success.
B.Attitudes learned in danger will last no more.
C.Copying others’ behavior is not a good idea.
D.Attitudes can be learned from one’s parents.
【小题4】What would be the best title for the passage?
A.Differences of Attitudes. B.Nature(本质) of Attitude.
C.Choices of Attitudes. D.Changes of Attitude.

A successful scientist is generally a good observer.  He makes full 36  of the facts he observes.  He doesn’t accept ideas which are not  37   on obvious facts,  and therefore refuses to accept authority as the only   38   for truth.  He always  39    ideas carefully and makes experiments to prove them.
The rise of    40    science may perhaps be considered to    41   as far back as the    42    of Roger Bacon,  the wonderful philosopher of Oxford,  who live    43    the years 1214 and 1292.  He was probably the first in the Middle    44    to suggest that we must learn science    45    observing and experimenting on the things around us,  and he himself    46   many important discoveries.
Galileo,  however,  who lived more than 300 years later (1564-1642),  was the greatest of several great men,     47    in Italy,  France,  Germany,  or England,  began by    48    to show how many important    49    could be discovered by observation.  Before Galileo,  learned men believed that large bodies fell more    50    towards the earth than small ones,     51    Aristotle said so.  But Galileo,  going to the    52     of the leaning Tower of Pisa,  let fall two  53    stones and proved Aristotle was wrong.  It was Galileo’s    54    of going direct to Nature,  and proving our    55    and theories by experiment,  that has led to all the discoveries of modern science.

I guess I always knew about the little fish treat, but this past summer it was all I could see. Pipin and Nemo were balancing on one front flipper(鳍), flying through hoops, dancing with the trainer, and we were all applauding — the little kids screaming with delight. That’s when the trainer, who wore a little treat bag on her belt, slipped Pipin and Nemo a fish. Each time they successfully performed a trick, they’d get an immediate reward.
These creatures weren’t really dancing, of course. They were performing a series of movements that they knew would produce a fish. It’s such a good show because the sea lions look like they’re having such fun. These talented performers who love to be in front of an audience seem almost human.
Somewhere in our faith journey, we all have a sea lion moment. You see how you’ve spent years jumping through hoops, balancing a ball on your nose, not because it’s really who you are, but because you’ve always done it and the system rewarded you for your performance. But when you’ve done that for ten or twenty years, you start to ask yourself, “Whose approval am I working for? What do I really believe?” Suddenly you see it: you’ve spent most all your life taking direction from other people. They’ve told you what to believe in, what to work for, what to value, how to live your life. You don’t want to end your life like Sinclair Lewis’s George Babbitt, the middle-aged real-estate broker(经纪人) who has everything and reached the top. But on the last page of Babbitt, George is speaking to his son Ted, who cannot follow in his father’s steps. He wants to leave college and head off on his own way. “Dad, I can’t stand it any more,” the boy says. “Maybe it’s all right for some fellows. Maybe I’ll want to go back some day, but now, I want to get into mechanics.” Babbitt, seeming old and subdued, says, “I’ve never done a single thing I’ve wanted to in my whole life!”
The Good-Bye Gate brings us naturally to a second passage, leading from dependency to self-possession. As you start separating from the whole worn-out system, you discover that where there is supposed to be a self, there really isn’t.
【小题1】The sea lions were pleased to perform in front of the audience because they ____.

A.will be punished if it refuses it
B.wants to win the trainer’s favor
C.wants to get audiences’ applauses
D.can get food as a reward that way
【小题2】While watching the sea lions’ performance, the author ____.
A.realized an important life philosophy
B.recalled the similar scene of last year
C.couldn’t help shouting and dancing
D.was happy to see them living freely
【小题3】By saying “we all have a sea lion moment”, the author means that ____.
A.anyone can make it so long as they work hard
B.sometimes we don’t act following our own will
C.we can also get rewarded if we do something well
D.every human being also has his happy moment
【小题4】What do you learn about George Babbitt?
A.He has been living a free life of his own.
B.His son ends up Babbitt family’s business.
C.He tends to agree to his son’s choice of life.
D.His son decides to follow his father’s steps.

People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. “Today we’re looking at science fiction becoming tomorrow’s reality—the driverless car.” The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the US government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
“Cars have become much more fuel-efficient, and new electronic features are making Hondas safer,” said Angie Nucci of Honda America. “A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes.” Other safety features include warning systems on the front and the sides of the cars. These systems help drivers, but don’t replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.
“By taking out drivers, you also remove most risks of an accident,” Kendall said. He said consumers, however, may be unwilling to lose control. “It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first.”
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.
【小题1】What can we learn from Paragraph l?
A. Volvo will be the first to sell driverless cars.      
B. Driverless cars are pointing us a faraway future.
C. Driverless vehicles are now legal in the whole USA.
D. Google’s self-driving cars have covered a long distance.
【小题2】We learn that Governor of California Jerry Brown_________.

A.helped design self-driving cars
B.supports self-driving cars on roads
C.considers self-driving cars science fiction
D.improved the self-driving car systems
【小题3】According to Richard Mason, what is the biggest challenge for driverless cars?
A.They are not allowed to run on the road.
B.Their technical problems remain to be solved.
C.They are now too expensive for consumers.
D.They are more dangerous for people on the street.
【小题4】Which is the best title for the passage?
A.The Benefits of the Self-driving Cars
B.The Biggest Challenge of the Self-driving Cars
C.Safer or More Dangerous Self-driving Cars
D.Self-driving Cars—Science Fiction Future Is Near

Passenger pigeons(旅鸽)once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks(群)so large that they darkened the sky for hours.
It was calculated that when its population reach its highest point, there were more than 3 billion passenger pigeons – a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant birds in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.
Sadly, the abundance of passenger pigeons may have been their undoing. Where the birds were abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.
By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood, which scattered(驱散)the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline. Soon the great flocks were gone, never to be seen again.
In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons, but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden in September 1, 1914.
【小题1】In the 18th and early 19th centuries, passenger pigeons _______.

A.were the biggest bird in the world 
B.lived mainly in the south of America 
C.did great harm to the natural environment 
D.Were the largest population in the US 
【小题2】The underlined word “undoing” probably refers to the pigeons’ _______.
A.escape B.ruin C.liberation D.evolution 
【小题3】What was the main reason for people to kill passenger pigeons?
A.To seek pleasure. B.To save other birds. 
C.To make money. D.To protect crops. 
【小题4】What can we infer about the law passed in Michigan?
A.It was ignored by the public. B.It was declared too late. 
C.It was unfair. D.It was strict.
