It’s puzzling, isn’t it? No matter where you try to tickle（使人發(fā)癢）yourself, even on the soles（腳底） of your feet or under your arms, you just can’t.
To understand why, you need to know more about how your brain works. One of its main tasks is to try to make good guesses about what’s going to happen next. While you’re busy getting on with your life, walking downstairs or eating your breakfast, parts of your brain are always trying to predict the future.
Remember when you first learned how to ride a bicycle? At first, it took a lot of concentration to keep the handlebars steady and push the pedals（踏板）. But after a while, cycling became easy. Now you’re not aware of the movements you make to keep the bike going. From experience, your brain knows exactly what to expect so your body rides the bike automatically. Your brain is predicting all the movements you need to make.
You only have to think consciously about cycling if something changes---like if there’s a strong wind or you get a flat tyre. When something unexpected happens like this, your brain is forced to change its predictions about what will happen next. If it does its job well, you’ll adjust to the strong wind, leaning your body so you don’t fall.
Why is it so important for our brains to predict what will happen next? It helps us make fewer mistakes and can even save our lives. For example, when a chief fireman sees a fire, he immediately makes decisions about how best to position his men. His past experiences help him foresee what might happen and choose the best plan for fighting the fire. His brain can instantly predict how different plans would work out, and he can rule out any bad or dangerous plans without putting his men at risk in real life.
So how does all this answer your question about tickling? Because your brain is always predicting your own actions, and how your body will feel as a result, you cannot tickle yourself. Other people can tickle you because they can surprise you. You can’t predict what their tickling actions will be.

“Human beings are ruder today because they are rushed and more ‘time poor’ than ever before,” says Patsy Rowe, “ Manners have fallen off the radar(雷達(dá)).” Due to our strong attraction to electronic equipment it is a wonder more people don’t wake up each morning and greet the singing birds with a complaint（抱怨）about the noise. Here are some examples of rudeness.
Some people prefer to do almost everything over the internet. To them, dealing with an actual human is like an evolutionary step backward. It feels very slow because humans don’t work at 4G speeds. When you have dinner with friends, you will often notice someone paying more attention to his mobile phone. We have programmed ourselves to think that every new message brings life-changing news, so taking calls and checking our texts are more important than talking to the people we are with. What is worse, some people even tend to send anonymous（匿名的） rude messages by email.
However, rudeness is never acceptable, Don’t assume it is OK to be rude if the person you’re in touch with won’t recognize you. If you have something awful to say, have the courage to face the person and say it, write a letter or email and sign it, or forget it. Upsetting people with unsigned messages is cruel and disgusting.
We shouldn’t blame technology for our shortcomings.Technology is here to help us, but we should not allow it to take over our lives. An important step ia acknowledging our shortcomings.People spend a lot of time pointing out bad manners but it would be even more help if we′d publicly acknowledge good manners when we see them.
【小題1】What can be inferred from the underlined sentence in Paragraph I?
| A．People can tell good from bad behavior. |
| B．Radar is able to observe human behavior. |
| C．People care little about their behavior. |
| D．Radar can be used to predict human behavior. |
| A．they are becoming less patient |
| B．they are growing too independent |
| C．they have to handle many important messages |
| D．they have to follow an evolutionary step backward. |
| A．We should applaud good behavior. |
| B．Technology can never be blamed |
| C．We should keep pointing out mistakes. |
| D．Technology will take over lives one day. |

A device that stops drivers from falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called Driver Alert, aims to reduce deadly road accidents by 20% - 40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.
Driver Alert is based on a computerized wristband (腕套). The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel (方向盤). A sensor in the wristband detects this pressing action and measures the time between
the sound the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.
【小題1】According to the text, Driver Alert ______.
| A．a(chǎn)ims to reduce tiredness-related accidents |
| B．has gone through testing at laboratories |
| C．a(chǎn)ims to prevent drivers form sleeping |
| D．has been on sale for 12 months |
| A．By sounding a warning. |
| B．By touching the wristband. |
| C．By checking the driving time. |
| D．By pressing the steering wheel. |
| A．a(chǎn)bout 400 milliseconds | B．below 500 milliseconds |
| C．over 500 milliseconds | D．a(chǎn)bout 4 minutes |
| A．moves more regularly |
| B．stops working properly |
| C．opens the window for the driver |
| D．sounds more frequently and loudly |

Dear Dad,
Today I was at the shopping mall and I spent a lot of time reading the Father’s Day cards. They all had a special message that in some way or another reflected how I feel about you. Yet as I selected and read, it occurred to me that not a single card said what I really want to say to you.
You’ll soon be 84 years old, Dad, and you and I will have had 55 Father’s Days together. I haven’t always been with you on Father’s Day but I’ve always been with you in my heart.
You know, Dad, there was a time when we were separated by the generation gap. You stood on one side of the Great Divide and I on the other.
The Father-Daughter Duel shifted into high gear（檔位）when you taught me to drive the old Dodge and I decided I would drive the 54 Chevy(雪佛蘭) whether you liked it or not. The police officer who sent me home after you reported the Chevy stolen didn’t have much tolerance（容忍） for a stubborn 16 -year- old girl, while you were so tolerant about it, Dad, and I think that was probably what made it the worst night of my life.
Our relationship picked up when I married a man you liked, and things really turned around when we began making babies. Somewhere along the line, the generation gap disappeared. I suppose I saw us and our relationship as aging together, rather like a fine wine.
But the strangest thing happened last week. I was at a stop sign and I watched as you turned the corner in your car. It didn’t immediately occur to me that it was you because the man driving looked so elderly and weak behind the wheel of that huge car. It was rather like a slap(打) in the face delivered from out of nowhere. Perhaps I saw your age for the first time that day.
I guess what I’m trying to say, Dad, is what every son and daughter wants to say to their Dad today. Honoring a father on Father’s Day is about respect and sharing and acceptance and tolerance and giving and taking. It’s about loving someone more than words can say, and it’s my wish that it never had to end.
I love you, Dad.
Love,
Jenny
【小題1】What caused Jenny to write the letter?
| A．Getting along well with her father. |
| B．Failing to find a satisfactory card. |
| C．Visiting a card exhibition at a mall. |
| D．Being away on previous Father’s Day. |
| A．Became better. | B．Changed unexpectedly. |
| C．Went worse. | D．Progressed unsteadily. |
| A．Jenny seldom saw her father drive that huge car. |
| B．Jenny knew her father’s real age from that day on. |
| C．Jenny’s father slapped her on the face somewhere. |
| D．Jenny had never realized her father’s being weak. |
| A．inform him of their conflicts |
| B．a(chǎn)pologize for her being stubborn |
| C．express her deep love to him |
| D．remind him of the early incident |

There are many kinds of sales. For example, a “back-to-school sale” is held near the beginning of the school year. Parents like the lower prices of the clothes and school supplies for their children.
A “midnight madness” event starts very late at night. An “early bird special” sale starts very early in the morning. This kind of sale is popular the day after Thanksgiving in November.
A favorite sale among many people is the “buy one, get one free” sale. You buy one thing and get a second one without cost. When people see the word “free” in an advertisement they know they are getting a good deal. As a matter of fact, it is not the case.
Another kind of sale is a “going out of business” sale. This is when a storeowner tries to sell all the goods in the store before closing the business permanently(永久地).
Let us say the store sells floor coverings. The owner lowers the prices and puts up a sign that says: “Going out of business sale. All items MUST be sold by tomorrow.”
People who buy the floor coverings think they are getting a special deal because everything must be sold in a short period of time. Then, days later they see the store did not close permanently. And they see the same sign that claims the store is going out of business. Some business owners really do not end the business. They just want to earn more money.
People also hold their own sales. They hold garage sales and yard sales outside their home. They sell things they no longer want. Groups such as religious centers or schools hold bake sales. They sell cakes, cookies and other baked goods to raise money.
In America, you can always find a good sale, no matter the day or time of year. There is the Independence Day sale, Veteran’s Day sale, clearance sale, sidewalk sale, red tag sale, white sale, blue light special, liquidation sale, half-off sale, warehouse sale, tent sale ...
【小題1】What does the passage mainly deal with?
| A．How to save money in shopping. |
| B．Different kinds of sales. |
| C．Shoppers’ ways to earn money. |
| D．Reasons for the popularity of sales. |
| A．A “back-to-school sale”. |
| B．A “midnight madness” event. |
| C．An “early bird special” sale. |
| D．A “buy one, get one free” sale. |
| A．Because it has a variety of school supplies. |
| B．Because it is held at the beginning of the school year. |
| C．Because it provides plenty school uniforms. |
| D．Because they can save money. |
| A．They want to close the business permanently. |
| B．They want to give special offers to customers. |

Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin (荷爾蒙催生素). Although known as the love hormone, it affects the sexes differently.
"Women tend to be social in their behavior. They often share with others. But men lend to be competitive. They are trying to improve their social status," said Professor Ryan.
Generally, people believe that the hormone oxytocin is let out in our body in various social situations and
our body creates a large amount of it during positive social interactions (互動) such as falling in love or giving birth.
But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.
Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship. Professor Ryan's recent experiment used 62 men and women aged 20 to 37. Half of the participants（參與者）received oxytocin. The other half received placebo (安慰劑).
After a week, the two groups switched with participants. They went tlirough the same procedure with the other material.
Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions.
The results indicated that, after treatment with oxytocin, men's ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better.
Professor Ryan thus concluded: "Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interactions. And the behavior differences between men and women are caused by biological factors (因素) that are mainly hormonal."
【小題1】What causes men and women to behave differently according to the text?
| A．Placebo. | B．Oxytocin. |
| C．The gesture. | D．The social status. |
| A．Oxytocin affects our behavior in a different way. |
| B．Our body lets out oxytocin when we are deep in love. |
| C．Our body produces oxytocin when we feel unhappy about others' success. |
| D．Oxytocin improves our abilities to understand people's behavior differences. |
| A．To test the effect of oxytocin on the ability to recognize social interactions. |
| B．To know the differences between friendship and competition. |
| C．To know people's different abilities to answer questions. |
| D．To test people's understanding of body language. |
| A．explaining people's behaviors |
| B．describing his own experiences |
| C．distinguishing sexual differences |
| D．discussing research experiments |
