How to Protect Yourself from Hackers Online
An increase in cyber-attacks (网络攻击) makes the Internet seem like a scary place these days. How can individuals protect or make it more difficult for hackers to access their information? Here are several tips that can help you protect against cyber-attacks:
1.
Hard passwords include upper and lower case letters, numbers and special characters. They should be at least eight characters in length. They should also not spell out words easy for hackers to find, like your pet's name or the name of a family member.
Change your password regularly
A very common mistake made by users is to create one hard password, but then never change it. Remembering a long list of complicated passwords can be difficult. But no password is unbreakable. Hackers are better able to hack multiple accounts if those accounts all have the same password. A password management service, like Dashlane or PasswordBox, can help you keep track of hard passwords. 2.
Clear your browser (浏览器) history
This goes for all the devices you use in a day – your home computer, your work computer, or your friend's iPad. Internet browsers like Firefox or Chrome keep track of where you've been and what you've done online. They keep records of every site you visited. 3. It is very easy for anyone who sees that information to steal a detailed record of your online activities.
Do not use free Wi-Fi
4. Often, a user does not need a password to connect to these wireless networks. These services might be useful, but they're also an easy way for hackers to access everything on your device.
Use anti-virus protection
There are many anti-virus services available for users. 5. Some anti-virus services are even free. They are a great way to have a professional help keeping users one step ahead of hackers.
A. Be careful while using thumb drive.
B. These services permit users to easily store and secure their passwords.
C. Make your password harder to hack.
D. They can offer many different types of computer protection.
E. An increasing number of public places now offer free wireless access to the Internet.
F. Information about what you sent from or saved on your computer can be kept for days or weeks.
G. Unless you really need it, it is best not to use it.
Until recently, scientists had mapped only about 20 percent of the sea floor. But our knowledge of the deep seas is changing because of information from satellites. Scientists have produced a new map that provides a detailed picture of the oceans. The map is expected to help oceanographers (海洋学家), industry and governments.
The new map is twice as detailed as the map made 20 years ago. David Sandwell is a geophysics professor at the University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean.
The scientists collected and studied information from two satellites. Some of the data came from the European Space Agency’s Cryo-2 satellite. It was placed in Earth's orbit to watch sea ice. The other satellite is the American space agency's Jason-1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar (声波定位仪) equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.
The new map shows the sea floor as it has never been seen before. It shows thousands of underwater mountains and places where continents pulled apart. It shows where earthquakes were active many years ago. They all are buried deep underneath the ocean floor.
David Sandwell says the map is a powerful tool for fisheries, those interested in protecting the environment and for oil exploration.
“The petrol exploration industry is interested in how to reconnect the continents, bring them back together tectonically so you can map the basins on one continental edge—say, Africa—and use that to establish where the similar basin would be on the other continental edge in South America.”
If scientists know that information, they may be able to find oil fields. The new data also will help scientists improve their estimates of ocean depths. This information can help ships travel safely and improve military operations and scientific projects worldwide.
Mr. Sandwell thinks scientists will make many more discoveries as they examine the new map and the information it provides.
1.Which one is not mentioned about the benefits brought by the new map?
A. Fisheries. B. Scientific projects.
C. Ship manufacture. D. Oil exploration.
2.What can we know about the new map?
A. It shows where earthquakes will happen.
B. It will be helpful to industry and governments.
C. It is three times as detailed as the old one years ago.
D. It shows the sea floor as it has ever been seen before.
3.The text is likely to appear in _________.
A. a newspaper B. an advertisement
C. a science magazine D. a finance report
4.Which of the following can be the best title for the text?
A. The detailed picture of the oceans
B. Underwater mountains and places
C. More discoveries about the oceans
D. Scientists create new maps of ocean floor
Where should an adventurous tourist go? After you’ve done sightseeing in London, shopping in New York, enjoyed the local food in Paris, and danced to your heart’s content at the Brazilian carnival, where else can you go? What attractive tourist destination awaits you?
Well, Antarctica sounds like the holiday of a lifetime! It's considered the last great wilderness on Earth. Just a few scientists in research stations share the icy landscape with penguins and other animals which can struggle with the low temperatures.
Tourism began in Antarctica in the 1950s and it's still small part. About 37,000 tourists are expected there this season, but many won't even leave the boat.
The BBC’s Juliet Rix visited the frozen continent and asked herself if she should be there at all, causing potential problems to such a sensitive environment. Her tour guide admitted that all visitors leave a footprint and they all go to the same places, the accessible coastline, which is also where the penguins and seals go to raise.
But some people believe that if carefully controlled, tourism can be good for Antarctica. It has no native population and it needs advocates. Visitors to the icy continent might be ready to support and even to fund its preservation. And they're likely to engage in the discussion about global warming, which has led to the melting of glaciers.
According to Rix, guidelines are followed when you’re about to set foot in Antarctica and tourists have to disinfect（消毒）their boots to make sure no alien species are introduced.
And once on land, there's no eating or smoking. Rocks, bone fragments—nothing should be taken as a souvenir and nothing should be left behind.
Tourists fortunate enough to visit the Antarctic must be aware that this is not their home and keep their fingers crossed that future generations will also be able to enjoy such breathtaking views.

Raymond Wang, 17, of Canada was awarded first place for a device that improves air quality on airplanes while cutting down the spreading of diseases at this year’s Intel International Science and Engineering Fair (ISEF).
According to Intel, Wang's system improves the quality of fresh air in a plane cabin by more than 190 per cent, while cutting diseases by up to 55 times, compared to conventional designs. Intel noted that Wang's invention could be easily and economically fixed into existing airplanes.
Two other teen researchers earned awards of $50,000 each at the event. One developed a technique to more quickly diagnose diseases caused by HIV. It’s the virus responsible for AIDS. The other invented a device to more quickly shut down undersea oil spills.
“Intel believes young people are the key to future innovation and that in order to confront the global challenges of tomorrow, we need students from all backgrounds to get involved in science, technology and engineering,” says Wendy Hawkins, executive director of the Intel Foundation. “We hope these winners will inspire other young people to pursue their interest in these fields,” she says, “and apply their curiosity and creativity to the common good.”
