题目内容
【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Some people make you feel comfortable when they are around. You spend an hour with them and feel you are already close friends. They are always good talkers. Here are several skills that good talkers have in common. If you follow the skills, they'll help you put people at their ease, and make friends with them quickly.
First of all, good talkers ask questions. Almost anyone, no matter how shy he is, will answer a question. One well-known businesswoman says,“At business lunches, I always ask people what they did that morning. ” From there you can move on to other matters—sometimes to really personal questions.
Second, once good talkers have asked questions, they listen to the answers. Your questions should have a point and help to tell what sort of person you are talking to. And to find out, you really have to listen carefully. Real listening at least means some things. If someone sticks to one topic, you can take it as a fact that he's really interested in it. Real listening also means not just listening to words, but to tones of voice.
Finally, good talkers know well how to “say goodbye”. If you're saying goodbye, you may give him a firm handshake and say, “I've really enjoyed meeting you.” Let people know what you feel, and they may walk away, happy and satisfied.
A. It's polite to listen to others with a smile.
B. You'd better change the subject if the voice sounds dull.
C. Don't be afraid to say so if you want to see that person again.
D. Common as the question is, it will get things going.
E. You can become a popular person.
F. And how he answers will let you know how far you can go.
G. These people have something in common.
【答案】E;D;F;B;C
【解析】本文介绍一些如何成为一个健谈的人的技巧,以便轻松与人交往。
(1)上一句说的是成为一个很好的谈话人,和他们很快交朋友,自然后面就应跟上E项中的成为一个受欢迎的人。故选E
(2)上一句I always ask people what they did that morning,这是很普通的问题,目的是让谈话继续下去,因此正好对应选项D。
(3)根据上句:这样你就可以转移到其他话题——有时是一些私人问题。因此下句应该是:并且他们的回答能让你知道能走多远。故选F。
(4)根据上一句Real listening also means not just listening to words, but to tones of voice提到“说话的语气”这个关键词,选项B与此相关,故选B。
(5)空格前一句:我真的很高兴遇见你。空格下一句:让人们知道你的感觉。因此可知空格填:如果你想再见到那个人,不要害怕这么说。故选C。
【题目】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 (连续的) 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 (琐事) 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.
