Notes:

**API stands for Air Pollution Index(指数).

**Particulate matter (PM10) is a major component of air pollution that threatens both our health and our environment. It consists of very small liquid and solid particles floating in the air.

**Sulfur dioxide(SO2) acts as an acid.Inhalation(吸入) results in labored breathing, coughing, or a sore throat and may cause permanent lung damage.

【1According to Graph 1, which of the following cities has the worst air pollution?

A. Qinhuangdao. B. Tianjin.

C. Qingdao D. Shenyang.

【2If your city is symbolized by either red or purple, the pollution in your city is .

A. Moderate or high. B. Moderate or slight.

C. Medium or high. D. Medium or slight.

【3Which of the following statements is TURE?

D. On September /span>8th the color-symbol of Beijing City’s air quality is ‘Blue’.

【4When more citizens are beginning to have labored breathing soon after they are in the open air, it suggests that .

A. there is a large amount of sulfur dioxide in the air

B. it is so cold that they may have caught a cold

【题目】How do people traditionally manufacture (制造) things? They usually start with a sheet of metal, wood or other material and cut, drill () 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.

1According 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

2What 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.

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

A. Amused. B. Objective.

C. Supportive. D. Negative.

HONG KONG In China, the smartphone battle used to be Samsung versus Apple. But not any more .

Over the summer, a Chinese company, Xiaomi, took the No. 1 position in China’s competitive market and became the world’s third-largest phone maker in the process.

Founded in 2010 , Xiaomi was late to the game. But a clever social media strategy and a business plan that emphasized selling services that work on the phone helped Xiaomi build frenzied support from young and trendy Chinese.

With people in China expected to buy 500 million smart phones in 2015 more than three times as many as will be sold in the United States, Xiaomi is likely to remain its place as one of the most powerful phone makers in the world’s most important market.

Now the company’s founders, who include the Chinese entrepreneur Lei Jun and the former Google executive Lin Bin, hope that status will help them take their brand globally.

Why Xiaomi gained such great success ? The reason partially lies in its fans’ participation. “Xiaomi fans have a high level of organization,” said Li Nan, vice president of the rival Meizu, “They love Xiaomi. It’s a form of idolatry.”

Han Yu, a 24-year-old studying for his master’s degree, is one of those idolaters. He, with tens of thousands of others, helps Xiaomi test its user interface by looking for bugs and offering suggestions. Much of his personal life revolves around Xiaomi. He said he was honored when his suggestion to create a private photo folder was adopted on phones by Xiaomi.

I really enjoy the sense of participation,” Mr. Han said.

For all its success, Xiaomi’s biggest challenge looms outside China. In 2013, the company hired Hugo Barra, an old friend of Mr. Lin’s from Google, to lead the company’s international expansion. “I would put China No. 1, India two, Indonesia three, then hopefully follow with Brazil and Russia,” he said. “The developed countries with tightly controlled carrier networks are not in the top five.” The countries Lin identifies all have large populations who still have not bought their first smartphone, meaning Xiaomi has a chance.

【1】The passage mainly tells us ______.

A. the competition between Xiaomi and Meizu

B. the cooperation between Xiaomi and Samsung

C. the battle among Smart phone Companies

D. the development and success of Xiaomi

【2】What helped Xiaomi win the support of young and trendy Chinese?

A. Its low price.

B. Its social media strategy and business plan

C. Its fashionable design.

D. Its international promotion

【3】Who takes charge of expanding Xiaomis market abroad?

A. Hugo Barra B. Li Nan C. Lei Jun D. Lei Jun

4The example of Han Yu is used to ________.

A. tell readers that the youth like to show off

B. prove Han Yu is very intelligent

C. show Xiaomi fans participation and devotion

D. introduce the designer of photo folder

【5】Why Xiaomi chooses less developed countries as targeted markets?

A. Because Xiaomi doesnt have to pay taxes.

B. Because more smartphone may be sold there.

C. Because Xiaomi was invited to develop there.

D. Because the young people there love Xiaomi.
