When _________ our national flag _______, we feel our hearts full of pride and strength.

A. watch; rising B. watching ; raising

C. watching ; being raised D. watch; to rise

C

【解析】

试题分析:句意:当看到我们的国旗被升起来,我们感觉到我们的心里充满了骄傲和力量。When引导的时间状语从句中主语和主句主语一致,且从句谓语动词为be动词,此时从句中的主语和谓语动词可省略。原句应为when we are watching our national flag,所以第一处填watching. 第二处为过去分词作后置定语,因为flag和raise之间为被动关系,故用过去分词表示被动。故选C。

考点:考查非谓语动词

A couple had a son eleven years after they married. They were a loving couple and the boy was the apple of their eye. When the boy was around four years old, one day the father was very tired after work so he asked his wife to pick up their son. The mother, who was very busy in the kitchen, totally forgot about it.

Later the boy lost his way on the street. When the son was found missing, the mother hurried to look for him, but she didn’t find him. The mother felt very sad and didn’t know how to face her husband.

When the father went to the police station after hearing that the son was missing, he looked at his wife and said just four words. What do you think the four words were? The husband just said "I love you, darling."

The son was missing. If she had picked him up earlier, this would not have happened. There is no point in blaming (责备) anyone. His wife had also lost her only child. What his wife needed at that moment was comfort and understanding from her husband. That is what the husband gave his wife. Several weeks later, with the help of the police, the couple finally found their lost son. The family’s relationship became stronger over that time.

Sometimes we spend lots of time asking who is to blame. We miss many chances to give each other support and let each other feel the warmth of human relationships. Get rid of all your unwillingness to forgive, selfishness, and fears and you will find the world is much more wonderful.

How do people traditionally manufacture (制造) things? They usually start with a sheet of metal, wood or other material and cut, drill (钻) and shave it to create a desired shape. Sometimes, they use a mold (模具) made of metal or sand, pour liquid plastic or metal into it and let it cool to create a solid part.

Now, a completely different method is gaining popularity.

On Oct. 9, 2013, London Science Museum kicked off its new exhibition, 3-D: Printing the Future, with over 600 3-D printed objects on display, including space probes (探测器), toy dolls and even human organs – basically any product you can think of, reported Live Science.

You might find it hard to believe that an object can actually be “printed out” like a picture. But it is not that hard to understand how it works. Just as a traditional printer sprays (喷洒) 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. And objects always come out in one piece, sparing you the trouble of putting different parts together afterward.

For example, 10 years ago a desktop 3-D printer might have cost £20,000 (200,000 yuan), while now it costs only about £1,000, according to the BBC. In fact, 3-D printers have been around for some time, but until recently they hadn’t been very popular since few people could afford them. Last year, though, saw a big decrease in the price of 3-D printers.

However, as 3-D printing technology becomes more commonplace, it may trigger certain problems. One of them is piracy (盗版). “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 on 3-D printing told Forbes News.

Even more frightening, the world’s first 3-D printed gun was successfully fired in the US in May of this year, which means that 3-D printing could potentially give more people access to weapons.

1.According to the article, in the future, 3-D printing technology will probably ______.

A. change the way people make products

B. be applied as widely in our daily lives as computers

C. forbid many countries to make purchases of weapons

D. take the place of normal printers and save lots of energy

2.What was the big event that happened in the 3-D printing industry last year?

A. Over 600 3-D printed objects were on display in an exhibition.

B. 3-D printing technology came to be used in various fields.

C. The world’s first 3-D printed gun was successfully made.

D. The 3-D printer became more affordable for consumers.

3.What is the author’s attitude toward 3-D printing technology?

A. Amused. B. Objective.

C. Supportive. D. Negative.
