Competition. It’s a simple word, yet a very complex word that covers many angles when it comes to how gasoline prices are determined. It seems so easy to explain, but don’t let that trick you—it’s incredibly difficult to explain and adequately understand.
Say you’re on a Sunday afternoon drive, and notice a gas station near you charging $3.50. Down the road a few miles, that price could easily be 10 or more cents higher or lower. The question is “how” or “why” is that? Think of it this way. Are you more likely to get a better deal on a car if there are two similar car dealers next to each other? Perhaps, because the dealers are too close. Say there is a third similar car dealer miles away. Is he going to be at the same level of competition and sell his cars for the same price as the two dealers next to each other? Likely not. He may charge more or less. Maybe people don't know there are two other dealers down the road. Maybe the dealer is almost outside of the city and the land value isn't as high, so his taxes aren't as high.
These situations do take place at gas stations. And more factors can impact what a station will charge. Timing can greatly impact what price a station charges as well! Many motorists fail to realize that the price a station pays for gasoline changes daily. If one station gets lucky and buys gas on Monday and the cost goes up Tuesday, the station that bought on Monday doesn’t necessarily have to raise prices like the station that bought on Tuesday. Maybe the station that got caught buying for a higher price on Tuesday will pass that higher cost on by raising its gas price.
Perhaps the difference is what brand the station is---branded stations usually pay a slightly higher cost for their gasoline. In return for paying a higher cost, those stations are guaranteed first supply in case of emergency situations. Independent stations don’t pay as much, but aren’t guaranteed supply.
While competition sounds easy to understand, there are always a large number of factors that could influence what one station charges. Keep in mind how many variables there are next time you fill up.What could be the best title for the passage?

Life is difficult.
It is a great truth because once we truly understand and accept it, then life is no longer difficult.
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 stand for a special kind of suffering especially forced on them or else on 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 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 a lot 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 want 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(指导).” It is for this reason that wise people learn not to fear but to welcome the pain of problems.Which sentence best express the central point of the passage?

If you have to miss a meal a day, which meal will cause you fewest health problems if you don’t eat it? If you have to make a decision of this type, most people (especially very busy people) will choose to skip breakfast.
However, many experts in the field of health consider breakfast ( the meal which “break” you “fast” ) to be the most important meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients (营养) we need to begin our working day with vigor(活力) and stay hopeful with good honor. However, many people skip breakfast or substitute a cup of coffee for a well balanced meal. What happens if we ignore the importance of breakfast?
One recent study conducted in the United States tested a large number of people. Participants(参加者) included both males and females who ranged in age from 12 to 83. The results showed that if a person eats an adequate(丰富的) breakfast, he or she will work more efficiently(效率高地) and more productively than if he or she skips breakfast or eats a very poor breakfast. This fact appears to be especially true if a person’s work involves mental(脑力的) activities. The study showed that if school-children eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate on their lessons for a longer period of time than if their breakfast is inadequate(不丰富).
The study also showed that contrary to what people believe, if you skip breakfast, you will not lose weight. This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing. So remember, if you want to lose weight, skipping breakfast will not help you. You will likely lose more weight if you decrease your other meals. According to experts, breakfast is the most important meal of the day because _____.
| A．a good breakfast breaks you down fast |
| B．you’ll lose weight quickly if you skip breakfast |
| C．breakfast provides what a person needs to work |
| D．after a long night, you’ll feel very hungry |
The underlined part “substitute a cup of coffee for a well balanced meal”(Para. 2) probably means _______.
| A．to exchange a cup of coffee for a well balanced meal. |
| B．To drink a cup of coffee instead of a well balanced meal. |
| C．To change a cup of coffee into a well balanced meal. |
| D．To regard a cup of coffee as a well balanced meal. |
The example of school-children in para.3 shows that _______.
| A．school-children will be quick and attentive all day if they eat breakfast |
| B．a proper breakfast will make mental workers more efficient |
| C．fruit, eggs, bread and milk are the best breakfast for mental workers |
| D．school-children who have breakfast are much brighter than those who don’t |
Which of the following is NOT true according to Para. 4?
| A．Some people skip breakfast because they want to be slimmer. |
| B．Most people who skip breakfast actually eat more for lunch. |
| C．People put on weight because they eat too much breakfast. |
| D．Skipping breakfast won’t help people who want to lose weight. |

| C．Surprising Results of a Study | D．Breakfast – A Meal That Breaks You Fast |

I’ve loved my mother’s desk since I was just tall enough to sit above the top of it. Mother sat writing letters. Standing by her chair, looking at the ink bottle, pens, and white paper, I decided that the act of writing must be a most wonderful thing in the world.
Years later, during her final illness, Mother kept different things for my sister and brother. “But the desk,” she said again, “is for Elizabeth.”
I never saw her angry, never saw her cry. I knew she loved me; she showed in action. But as a young girl. I wanted to have heart-to-heart talks between mother and daughter.
They never happened. And a gulf opened between us. I was “too emotional (易动感情的)”. But she lived “on the surface (表面)”.
As years passed and I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive me.
My hope turned to disappointment, then little interest and, finally, peace – it seemed that nothing happened. I couldn’t be sure that the letter had even got to Mother. I only knew that I had written it, and I could stop trying to make her into someone she was not.
But the present of her desk told me, as she’d never been able to, that she was pleased that writing was my chosen work. I cleaned the desk carefully and found some papers inside – a photo of my father and a one-paper letter, folded and refolded many times. It was my letter.

| A．Mother was cold on the surface but kind in her heart to her daughter |
| B．Mother was too serious about her daughter in words |

| B．The author and her mother love each other, but didn’t say it out |
| C．Neither the author nor her mother had a happy family. |

I worked hard for a whole week. So I decided to relax and went out of town with my son for the 1 . When we were walking on the street, we felt a little 2 .

If you lose your wallet, how often do you think someone will be kind enough to return it to you, with cash and credit cards?
Some people may be greedy, and others are simply too lazy to bother(打搅) with the trip to the post office to send back a wallet to a stranger. But according to a psychology study by Dr. Richard Wiseman, there’s one thing that’ll greatly increase your odds of being reunited with a lost wallet: a photograph of a cute baby.
In the study, hundreds of wallets were scattered(分散) around the streets of Edinburgh, Scotland. The psychologists wanted to see how many strangers would take the trouble to return them to the addresses listed on the drivers’ licenses inside—but more than that, they wanted to find out what would make a person more likely to help out a stranger.
To finish this, they included personal things in most of the wallets: some included a photo of a happy elderly couple, some contained a cute puppy, some contained a family portrait, and some held a photo of a lovely baby. Others had receipts(发票) showing that the wallet’s owner had recently donated to a charity（慈善）. Some contained no personal details.
As the psychologists soon discovered, the sight of a smiling baby is enough to warm nearly any heart: only one in ten of the strangers who retrieved such wallets did not return them. In contrast, the second most successful image, the puppy, had a 53% return rate. When the wallet included no photograph, it stood only a one in seven chance of being returned to the owner.
The success of the baby photograph shows a human compassion(同情) for the young that’s been passed down through the ages, according to Dr. Wiseman. “The baby kicked off a caring feeling in people, which is not surprising from an evolutionary perspective(进化的角度),” he told the Times.
To ensure our species’ survival, scientists think that we must feel empathy and compassion for our young. Scientists say that this study supports the argument that we won’t feel compassion only for our own babies, but for any that we see—hence, the strong desire a stranger would feel to return a wallet to the baby’s parent.
On a more basic level, the study also provides a great tip to help ensure that if your wallet is ever lost, you’re more likely to get it back. “If you want to increase the chances of your wallet being returned if lost, gain a photograph of the cutest baby you can find and ensure that it is clearly displayed,” said Dr. Wiseman.The main purpose of the psychologists’ leaving hundreds of wallets around was to find out________.
| A．whether people were as honest as before |
| B．what made people willing to help strangers |
| C．what kind of feelings could be caused by a smiling baby |
| D．how evolution influenced human beings |
The underlined word “retrieved” in Para. 5 probably means “________”.
| A．picked up | B．spread out | C．found out | D．looked for |
Why did people return a wallet with a photograph of a cute baby in it?
| A．Because the wallet was not attractive enough to keep. |
| B．Because the sight of a baby could cause a caring feeling in them. |
| C．Because they were curious to know the parents of the baby |
| D．Because the sight of a cute baby reminded them of their own children. |
If there are 30 lost wallets with a photograph of a cute baby, how many of them will probably be returned?
| A．Only 3. | B．About 15. | C．20 or so. | D．About 27. |
We can learn from the last two paragraphs that________.
| A．humans usually have compassion for the young |
| B．the caring feeling in people is gone during evolution |
| C．scientists believed that people only feel compassion for their own babies |
| D．a wallet with a cute baby’s picture in it cannot be lost |
