SEE a cell phone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hit­ting "print" on your computer.
You might find it hard to believe that you could actually "print" an object like you would a picture. But it is not that hard to under­stand how it would work. Just as a traditional printer sprays (喷) ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.
Instead of ink, the materials the 3-D printer uses are mainly plastic, resin (树脂)and certain metals. The thinner each layer is --- from a millimeter to less than the width of a hair ---  the smoother and finer the object will be.
This may sound like a completely new technology, but the truth is that 3-D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.
Last year, though, saw a big change in the 3-D printing industry--- printers became much cheaper. For example, 10 years ago a desktop 3-D printer might have cost £20,000 (200,000 yuan), while now they cost only about £ 1,000, according to the BBC.
Taken out of the factory and in­troduced to more diverse and com­mon uses, 3-D printing can create just about anything you can think of ---flutes (笛子), bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell Univer­sity in New York have just made an artificial ear using a 3-D printer, accord­ing to Science Daily. The fake ear looks and acts exactly like a natural one.
However, as 3-D printing becomes more commonplace, it may bring about certain problems --- such as piracy. "Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3-D printer, who will visit a retail (零售的) store again?" an expert in 3-D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3-D printer to print out a fully functioning gun?
【小题1】According to the article, in the future, the 3-D printing technology will ___.

—Ok, I guess. My grandma kept cooking and cooking, so I just kept eating.

Many people like the feeling of the gentle wind in spring. Many like to see the falling leaves dancing in the wind in autumn. But sometimes, when the wind becomes a storm, it can be very destructive (毁灭性的).
A series of such storms struck the US last month and caused very serious damage and human pain.
Every year, major storms cause many problems around the world. There is nothing people can do to stop these powerful forces of nature. But new techniques are helping scientists to predict how, when, and where big storms will happen. The more exact scientists’ warnings are, the better people can prepare for the storms.
Predictions are improving. “We’ve gotten better over the years, especially the last few years,” says Phil Klotzback, a scientist at an American university. How is a storm formed? Even if scientists know where a storm will happen, winds can suddenly change, carrying the storm to a new direction. “For a hurricane to happen, conditions have to be just right,” Klotzback says.
First, the ocean water needs to be warm enough so that it evaporates and rises into the air. As it rises, the air containing drops of water cools and turns back into liquid. This process gives off heat. This produces energy like an engine that causes winds to increase. It drives the formation of a hurricane.
If wind speeds reach 40 miles per hour, the system is called a “ tropical storm”, and it gets a name. At 75 miles per hour, it becomes a hurricane. Hurricanes that hit the US start when a thunderstorm forms off the coast Africa. Storms also develop over tropical waters in other parts of the world.
On average, 60 or 70 storms form off Africa every year. About 10 of them get names. There are usually about six hurricanes. Two tend to be very big, with winds of 115 miles per hour or a bit higher.
The hurricane season lasts from June to November. Ninety percent of all hurricanes hit in August, September and October.
【小题1】According to the text, hurricanes usually ________.

Having put down your pens at the end of the college entrance exam, you have ended 12 years of hard study. Forget your studies for a while. It’s time to enjoy yourselves!
There are many ways to celebrate this special month of graduation. You can have photos taken with your classmates and teachers, or dine out together and exchange gifts.
High school students in Western countries such as the United States and Canada usually have a prom to mark their graduation. It’s to mark the time kids turn into young men and women. After the prom, teenagers either go to college or find a job. It means they are no longer as dependent on their parents as they were before.
At the prom, boys usually dress in dinner jackets and bow ties, though many different types of formal clothes are worn. Traditionally, girls give boys matching boutonnieres ( 佩带在扣眼上的花). Girls traditionally wear formal dresses, or dress to shock or be noticed, in shiny or brightly colored materials.
Common prom activities include dining, dancing, the crowning (加冠) of a prom king and queen, and just talking to friends.  In some cases, high school students collect funds for their class prom through the four years of their high school.
High schools in or near large cities may rent ballrooms at expensive hotels or, to be unusual, in a pleasure cruise boat.
But often costs are cut by simply using the school gym. Students make a lot of effort to decorate the gym to make the event special. The music played at the prom will be the most popular kinds, like rock and hip-hop.
The students elect the Prom Queen. She is partnered with a Prom King who is elected similarly. These are great honors that the pair take very seriously. The two dance with each other to celebrate their election.
【小题1】The word "prom" is probably closest in meaning with________.

—I don’t know          makes her different from others.
—Confidence, I think.
