The Indian government may use 3D paintings as virtual speed breakers（减速带） on major highways and roads, in order to check speeding and careless driving, and finally make its deadly roads a little safer. "We are trying out 3D paintings used as virtual speed breakers to avoid unnecessary requirements of speed breakers," India's transport minister Nitin Gadkari wrote.
The optical illusions(视觉错觉) are supposed to encourage drivers to slow down automatically. Earlier, India had ordered the removal of all speed breakers from highways, which are considered to be a safety hazard for high-speed vehicles. India has the highest number of road accident deaths in the world. According to the World Health Organisation, over 200,000 people are killed by road accidents.
The use of optical illusions as speed breakers was first pioneered in the American city of Philadelphia in 2008, as part of a campaign against speeding motorists. The technique has also been tried out in China to create floating 3D crossings. In India, cities such as Ahmedabad and Chennai have already experimented with 3D zebra crossings in the last one year. In Ahmedabad for instance, a mother and her daughter, both artists, have painted 3D crosswalks in the first few months of 2016. The artists say their motto is "to increase the attention of drivers", and that the concept has been successfully tested in accident-prone zones on a highway.
However, critics argue that once drivers know that these speed breakers are visual illusions, they may ignore them. Others also point out that India's decision does not consider the safety of a large number of pedestrians. In the end, the new policy may be just one step towards improving road safety.
1.Why are 3D paintings used on main highways and roads?
A. To make the surroundings more beautiful.
B. To attract the attention of tourists.
C. To reduce the rate of traffic accidents.
D. To show the advanced technology.
2.Which of the following words is closest to the meaning of “hazard” in paragraph 2?
A. Reminder B. Threat
C. Regulation D. Theory
3.What can we learn from Paragraph 3 and 4?
A. Philadelphia, the U.S.A is th second place to use virtual speed breakers in the world.
B. The idea tested in Ahmedabad recently has been a failure.
C. The new policy of 3D zebra crossings must be carried out smoothly.
D. The use of optical illusions as speed breakers is controversial in India.
4.What do we know about 3D zebra crossings from the passage?
A. They can vastly lower the death rate in India.
B. They have been widely used in India so far.
C. They are designed to increase drivers’ attention.
D. They are welcomed by both drivers and pedestrians.

【改编】Australian scientists say an organic compound used by Indian women to paint dots or bindi on their foreheads could hold the key to a breakthrough in cancer treatment. Rose Bengal (玫瑰红)was first used in the early 1900s as a dye for food, textiles and cosmetics. But now it is proving to be a useful weapon in the fight against skin cancer.
Television advertisements constantly warn of the dangers of overexposure to the fierce sun. Among them is the possibility of the disease melanoma(黑瘤), a type of skin cancer. More than 1,200 Australians die every year from the disease.
Initial trials of a solution of Rose Bengal injected into some melanoma cells have had a 75 percent success rate in controlling the disease. Professor John Thompson, the director of the Melanoma Unit at the University of Sydney, says this organic dye could become a powerful cancer-fighting treatment.
“We believe it works by getting into the tumor(肿块) cells and causing them to self-destruct. But the exact mechanism by which it works is not totally clear. It’s not useful for people who have a primary melanoma. The treatment of primary melanoma is surgical excision(切除),”he said. “It’s useful to inject tumors for people who have recurrences; when the primary treatment has failed and when recurrence in the area, or at more distant sites has occurred.”
About 90 percent of Australians who develop melanoma survive thanks to early diagnosis and treatment. If left untreated, however, the disease can be fatal.
Convincing younger people in Australia about the dangers of overexposure to the sun is a battle campaigners are constantly waging.
Veronica Manock, a 21-year-old student, had two major operations to remove a cancerous tumor from her leg.
“I’ve had a lot of friends who just said ‘I thought it was just, you know, I’ll get a mole(痣) cut out and that’s it’, whereas I don’t think people realize how much danger they’re putting themselves into and how easy it is to stop something like this happening to you just from doing little things,”said Marock.
Other researchers in Australia are investigating genetic treatments to skin cancer. There is a pressing need for such research to produce effective treatments. Australians, the majority of whom are fair-skinned(浅肤色的), are four times more likely to develop a melanoma than people in Canada, the United States or Great Britain.
1.Which can be the best title of the passage?
A. Rose Bengal —the cause of skin cancer.
B. Rose Bengal —a tool to fight against skin cancer.
C. Skin cancer—the first killer.
D. Melanoma—the threat to health.
2.What does the underlined word “fatal” mean?
A. Curable. B. Serious. C. Deadly. D. Self-healing.
3.From what Veronica Manock said , we can know _______.
A. people haven’t realized overexposure to the sun is dangerous
B. mole on the leg is dangerous.
C. people can do nothing to protect themselves from melanoma
D. nothing can be done to deal with the disease.
4.Who are likely to develop a melanoma?
A. Englishmen. B. Canadians.
C. Americans. D. Australians.
5.In which section of a newspaper does the passage possibly appear?
A. Economy. B. Agriculture. C. Health. D. Fashion.

Counterfeit (假冒的) goods, or false versions of products, may cost the government of Kenya as much as $1 billion each year. The fake goods also hurt business owners who find it hard to keep customers. But information technology is being used to try to stop the problem. Jemima Mwafigu is a 34-year-old businesswoman who sells products like perfume. But in the first year of running her business, she found it hard to keep customers because of counterfeit goods.
Ms. Mwafigu says her business has improved since she began using a smart phone application called Barcode (条码) Scanner. The app is used to authenticate (验证) products. It checks to make sure the products are not counterfeit.
“With this application I'm able to scan the bar codes of each perfume and instantly I get the production date, the expiration date and I'm able to know the safety,” she says. “That way, I have confidence in selling to my customers.”
In 2010, Kenya created the Anti-Counterfeit Agency, or ACA, to fight against illegal trade. The ACA has successfully asked government officials for stronger punishments for counterfeiters.
Agnes Karingu is the agency’s acting director for research and awareness. She says the ACA is trying to stay one step ahead of those making fake goods.
“We are also looking into IT solutions where we can be able to use SMS programs, bar codes and information sharing,” she says. “The end users of the products will actually be able to get the authentication information, and this information comes back to ACA and intellectual property rights holders.”
The agency is testing another program called Allvirtuous. The application is another way to find out if a product is real or not by scanning its barcode. The barcode information is sent to a database. Then a result is sent back to the app.
The International Chamber of Commerce is a global business organization. It says the value of counterfeit goods produced around the world is expected to be more than $1.7 trillion (万亿) this year.
1. What’s the main purpose of this passage?
A. To tell us that Information Technology is developing fast.
B. To persuade us to resist counterfeit goods.
C. To advise us to use phone apps while going shopping.
D. To inform us that phone apps can help stop counterfeiters’ trade.
2. Why did Kenya create ACA?
A. To raise people’s awareness of counterfeit goods.
B. To ask the government to punish counterfeiters.
C. To deal with illegal trade.
D. To look into IT solutions.
3.The underlined phrase “expiration date” in Paragraph 3 means the time when __________.
A. the product is unable to be used
B. the product is packed
C. the product is first out of the factory
D. the product is made
4.What can we infer from the last paragraph?
A. Measures should be taken immediately to prevent counterfeit goods.
B. The business of counterfeit goods is falling off.
C. The value of counterfeit goods is likely to be more than $1.7 trillion this year.
D. Counterfeit goods make a great contribution to the world economy.

Downloading files is one of the primary uses of the Internet. You can find virtually anything online, and chances are that you've been downloading files ever since you started using your computer. Your Operating System will attempt to put all of your downloads in one central location, but eventually you may have downloaded files all over your computer. Knowing how to quickly find your downloaded files can save you a lot of time and headache.
● Check your Downloads folder（文件夹）. Windows includes a Downloads folder that acts as the default (默认的) download location for most programs for every user. There are a couple of ways you may be able to find your Downloads folder:
Click the Start menu and then click your user name. You should see a Downloads folder in the window that opens.
Open Windows Explorer ⊞ Win+E. Your Downloads folder may be listed in the left frame under "Favorites" or "Computer/This PC".
Press ⊞ Win+R and type shell: downloads. Press ↵ Enter to open the Downloads folder.
● Check other locations. If you download with a lot of programs, chances are that your downloads have become a bit spread out. Other popular places for your downloads to appear are your Desktop and your Documents/My Documents folder.
If you have a secondary drive that acts as a file storage, check to see if you've created a download folder on it as well.
● Search for the file. If you know the name of the file you downloaded, you can search for it to quickly open it. Press ⊞ Win and start typing the name of the file. You should see it appear in the search results.
● Open your downloaded files. You shouldn't have much difficulty opening most files that you download online, but you may run across a few file types that can give you problems. See the guides below for details on opening these troublesome files.
