Black Friday
Thanksgiving is always on a Thursday. The day after it has been known as Black Friday. It is the start of the holiday shopping season, and it has been the busiest shopping day of the year in the US since 2005.
Most stores offer big sales on Black Friday. They open their doors quite early in the morning. They try to attract shoppers with big discounts (打折). Some items (商品)like TVs and cloths are much cheaper than usual. Stores may even lose money on these items. They hope that shoppers will buy gifts for other people while they are in the store.
Black Friday is a great time to go shopping. However, there are problem. The biggest one is that there are not enough low-priced items. Each store may only have a few. These items are in great need, so people stand in long lines to get them. They may wait three to four hours before a store opens. They may be hoping to get a low price on a TV or computer, but not everybody can get one. Some people leave, disappointed.
The situation makes people worried. Some Black Friday events have been crazy. There have been fights over toys among shoppers. Some workers have even been hurt by large crowds. But most Black Friday events are safe and fun. Still, if you plan to go, you will expect large crowds and a bit of pushing.
So where does the name “Black Friday” come from? It was first used in Philadelphia in the 1950s. The police called this day Black Friday because of the heavy traffic it caused. In the 1960s, stores tried to rename the day “Big Friday”. It did not stick. The name “Black Friday” continued to spread across the country. It seems that it is here to stay.
Now people all over the country take part in Black Friday events. It is even spreading to other parts of the world. Stores have held Black Friday events in the UK, Australia, and Brazil since 2012. In Mexico, stores offer a weekend of discounts every year. They call it “El Buen Fin”, which means “the good weekend” in Spanish. I guess people everywhere like to buy things on sale.
Is Black Friday the start of the holiday shopping season?

“ Listen carefully to what I say.” the time traveler said. “I shall tell you something that you will not agree.”
“Why will we not agree?” I asked.
“Because the science and mathematics you know are not correct,” he said, “You believe there are only three dimensions(三维空间）---length, breadth(宽）and thickness.”
“There is nothing to agree with that,” the youngest member of our little group said.
“Exactly!” the time traveler answered. “But there is also a fourth dimension---time.”
“We all know about time,” another member of the group said,” Time passes.”
“I do not agree,” the time traveler said. “Length, breadth and thickness do not pass. They stay in the same place in space. We move about them. I can prove that time is the same. It does not pass. We move in time the same way that we move in length, breadth and thickness.”
None of us believed the time traveler, and we argued with him for many hours.
“If we could travel back in time,” the scientist said, “we could do things to change the future.”
“If we could travel forward in time,”the doctor(博士）said,“We could do things that change our present.”
The time traveler smiled. “It is clear,” he said, “that there is only one way I can show you that I am right. We must do an experiment. Please wait here.”
He left the room and soon returned, carrying what looked like a clock.
“This is a model of a time machine. It took me two years to make it.” the time traveler said, “I want all of you to understand that when I start the machine, it will immediately travel in time and disappear from present.”
He turned to the youngest of us. “Give me your hand.” he said.
The young man put out his hand. The time traveler took it and placed it on the machine. Immediately, there was a sudden wind, and the little machine disappeared.
I was certain this was not a trick, but the doctor was not so sure.
“Are you asking us to believe,” he said, “that the machine is now in the different time?”
“Certainly! In my laboratory, a full-size machine is almost complete. As soon as it is complete, I shall send myself on a journey through time. Would you like to see my machine?”
“Are you serious about this?” the doctor asked.
“I have never been more serious about anything,” the time traveler said, “Come.”

How long did it take the time traveler to make his model time machine?
