【題目】We see the world in three dimensions. Now, we can print in three dimensions, too, thanks to a manufacturing process: 3D printing.

3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.

The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive (連續(xù)的) layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizon till (水平的) cross-section of the eventual object. Today’s 3D printers are being used to print everything from design models to jewelry, crafts, product parts, body parts, and even food.

3D printing starts with making a virtual design of the object you want to create. This virtual design is for instance a CAD (Computer Aided Design) file. This CAD file is created using a 3D modeling application or with a 3D scanner (to copy an existing object). A 3D scanner can make a 3D digital copy of an object.

You will have to prepare a 3D model before it is ready to be 3D printed. This is what they call slicing. Slicing is dividing a 3D model into hundreds or thousands of horizontal layers and needs to be done with software.

Sometimes a 3D model can be sliced from within a 3D modeling software application. It is also possible that you are forced to use a certain slicing tool for a certain 3D printer.

When the 3D model is sliced, you are ready to feed it to your 3D printer. This can be done via USB. SD or WiFi. It really depends on what brand and type 3D printer you have.

When a file is uploaded in a 3D printer, the object is ready to be 3D printed layer by layer. The 3D printer reads every slice (2D image) and creates a three dimensional object.

Before you pick up a 3D printer and experimenting in the 3D world, consider how big the objects you might want to create. If your goal is to print foot-long rulers, you’ll fall short of that goal if the printer you choose can only handle objects smaller 6 inches in height and width.

Another reality check is print speed. You’ll be able to knock out a day’s worth of chores (瑣事) while the printer is running, with a typical 4-inch model requiring as many as 12 hours to print. As with ordinary printers, print speed also depends on how well it prints.

Title: A Beginners’ Guide to 3D Printing

What is 3D printing?

3D printing is a process of making three-dimension objects out of a digital file.

An object created with 3D printing 【1】 of a number of layers of material.

How does 3D printing 【2】?

The first 【3】is to make a virtual design of your 【4】 object.

A 【5】 3D model is sliced into a huge number of layers with software or some 【6】 for a certain 3D printer.

The sliced model is 【7】 to a 3D printer

The 3D printer 【8】 the layers into an entire object step by step.

What else do you need to know?

The【9】of what you intend to make is a factor in your choice of a 3D printer.

Print speed is associated with print 【10】.

【題目】Whenever the sun dropped and the blue sky came up, my father and I used to climb the mountain near my house.

In fact, I hated it at that mountain, but my father said to me, “You can always see a beautiful sky at the top of the mountain, but you can’ t see it before you reach the top. Only there at the top can you see all of the nice things, just like in life. ”

At that time, I was too young to understand his words. But later after that, I got new hope and confidence. I found myself standing at the top of the sky, which was as clear as crystal.

【題目】People and animals often enjoy loving relationships with each other. When people adopt domesticated(家養(yǎng)的) animals into their families as pets, animals give humans the blessings of companionship and fun in return. In the wild, animals sometimes carry out dramatic rescues of people in dangerous situations, miraculously(奇跡般地) sensing human needs and jumping in without fear to help.

In 2000, a 6-year-old boy named Elian Conzalez left Cuba on a boat bound for Florida in the United States, but the boat sank and everyone aboard drowned except for Elian and two adults. Elian and the other two survivors held onto inner tuber for 48 hours to try to stay afloat in the sea. After a while, however, Elian began to lose strength, slipping under the water and then grabbing the tube again as he fought to stay alive.

A small group of dolphins noticed Elian struggling and swan over to him to help. The dolphins formed a circle around the inner tube and took turns using their noses to lift Elian until fishermen working in the area discovered and rescued Elian and the two adults who floated nearby. The fishermen reported that, when they discovered Elian, he was repeating a prayer that his mother had taught him before drowning, asking guardian angels to protect him.

Miraculously, the dolphins knew that a child would need more help than adults, so they focused on Elian —and they figured out exactly what needed to be done and cooperated carry out that plan successfully. They made it!

【1】Why did Elian slip off the tube?

A. He was tired out.

B. The dolphins helped him.

C. The two adults pushed him.

【2】How did the dolphins save Elian Conzalez?

D. They stopped Elian slipping under the water.

【3】Which of the following words can be used to describe Elian Gonzalez?

A. Confident and strong.

B. Determined and lucky.

C. Friendly and optimistic.

D. Adaptable and aggressive.

【4】Which could be the best title?

A. Prayer Doing Wonder

B. Elian’s Narrow Escape

C. The Dolphins Who Rescued Elian

D. Animals: Human Being’s Angels

One night in February 1962, John H. Glenn. Jr., flew over Australia. The man in the Mercury(水星) capsule（宇宙飛行容器）was alone, but friendly voices reached him by radio. On the dark land 100 miles below, he saw a sprinkling of light. They marked the city of Perth, where people had turned on their lights as a greeting to him.

John H. Glenn. Jr., was the first America to orbit the earth. For his flight, the tracking network（跟蹤網(wǎng)絡(luò)） covered 60,000 route miles. Five hundred men worked in the stations along the route. Since his flight, the network has grown. Today, it covers more than 100,000 route miles and has about one hundred stations.
