Researchers recently found that hackers took control of 300,000 home routers(路由器). Once your home router has been controlled, hackers could redirect your network to malicious websites controlled by hi-tech thieves who could then steal your online back details and other sensitive data. However, there are some simple steps you can take to protect your router.
Say no to 12345 passwords
First, never leave your router open without a password and make sure you change both your Wi-Fi and router login password from the default one it comes with. If you use the default password , this could give someone access to the router setup, which could allow them to change your router settings, including viewing any security keys.
Don't broadcast it
Make sure you don't show up in other people's wireless network scans. Know your network name so you can easily enter it into any devices you want to access that network. Other people do not need to know your network name. To prevent outsiders from seeing your network's name and attempting to join your wireless network, turn off broadcasting in your router's settings.
Invite only please
One way you can ensure no one else joins your network without your permission is to enable your router to only allow certain devices to connect, and ban all others. To do that you can filter by media access control (MAC) addresses.
Turn it off
This is a simple piece of advice that can go a very long way in keeping you safe. Simply turn off your router when you're not using your network. If you're at work all day and no one's home, why keep it running?
Build a firewall
The firewall built into your router prevents hackers on the internet from getting access to your PC so it's always worth enabling it to help add an extra layer of security. However, it does nothing to stop people in range of your Wi-Fi signal from getting onto your network – and as said, a router in the wrong place means your Wi-Fi signal could reach pretty far.
For further protection, you should run software firewalls on the individual PCs on your networks.
1. If you use the default password, ______________.
A. your home router will be linked to some bad websites.
B. you will find it’s very convenient to surf the Internet
C. your home router will be changed for new settings.
D. you will fail to use your own login password
2. What should be done to shelter your wireless network?
A. To build a firewall into your router.
B. To think out a complicated login password and use it.
C. To shut off your router when you find it not safe.
D. To switch off broadcasting in your router settings
3. The purpose of the passage is to tell____________.
A. how to keep your Wi-Fi network secure
B. how to deal with your home router efficiently
C. how to locate the hackers on the Internet
D. how to prevent others from joining your network.

A Koala Isn’t a Bear
Koalas remind people of teddy bears.They have thick fur and large ears.Their broad, flat nose makes them look cute, similar to teddy bears.In fact koalas aren’t cute.They have sharp teeth and very sharp claws! Koalas are marsupials.This means the mother carries her baby in a pocket while it develops, similar to a kangaroo.The baby koala lives in its mother’s pocket for the first six months of its life.
The name “koala” comes from a native Australian word that means “no drink”. The koalas get almost all their water from the eucalyptus(桉樹) leaves they eat.That’s where they get their food too.Koalas eat only eucalyptus leaves, and only the leaves of certain eucalyptus trees.The eucalyptus trees are where the koalas live.It’s also where they sleep.Koalas sleep about nineteen hours a day!
Why do they sleep so much? Some people think it’s because they’re lazy.But koalas aren’t lazy.They sleep so much because there isn’t much nutrition in eucalyptus leaves.Koalas store hardly any fat, so they must save their energy.One way to do this is to move slowly and sleep a lot.
After a day of sleeping they like to move around and eat just after sunset.They live alone most of the time.Koalas are very protective of their trees.If a koala sees another koala eating in its favorite tree, it might tell the other koala to leave by “barking” at it.Koalas do “talk” to each other.Besides barks, the males make a deep grunting sound.The mothers and babies talk in soft clicking sounds.If they get scared they may scream like a baby.

With the press of a button, a person with severe spinal cord (脊柱)injuiy is able to walk again, thanks to the Walking Assistive Exoskeleton Robot (WAER).
Powered suits that could help paralyzed (癱瘓)people walk and others lift and carry heavy loads with ease have been a dream since late 19th century. But they can realize their dreams in the 21st century.
The 20-kilogram robot has four battery-powered motors that can run for up to three hours. Inventor Wu Chenghua, from Taiwan’s Industrial Technology Research Institute, says it has successfully been in tests on 12 patients. “We have learned from our research process that patients whose injuries are below the fourth chest joint (關(guān)節(jié))are able to use our robot to stand, walk and sit down,” he said.
Since walking contributes to muscle exercise, Wu says patients receive some additional benefits. “In the clinical process, we would check their bone mineral density (密度),and we found that the bone mineral densities of these patients had been improved.” he said. Wu says his exoskeleton may be available for consumers by 2018.
Meanwhile, baggage handlers at Tokyo’s Haneda Airport will soon start testing a similar robot, developed by the Japanese firm Cyberdyne. The battery-powered robot weighs only 3
lift a heavy object, the machine monitors the movemen”,says Yoshiyuki Sankai, the developer and CEO of Cyberdyne.
“This robot suit monitors the signal from the human nerve (神經(jīng))system to support the waist’s movement,” Sankai said, “It self-adjusts the level support to reduce the load on the human waist, light and smart. We believe that it will change the life of paralyzed people in many ways and have a promising future.”
1.With the help of WAER, patients will probably .
A. recover from spinal cord injury
B. improve their bone mineral density
C.walk as fast as normal people
D. monitor their waist’s movement

You may think that an underground town of 3,500 people is something out of a science-fiction film. You may not believe that such a town has shops car parks, hotels, restaurants, cafes and much more. Well, Coober Pedy in Australia is just such a place.
Miners and their families choose to live like this, hoping to get rich looking for the precious stones that Australia is famous for --- opals(蛋白石). Living underground is the only way to be away from the sandstorms and the high temperatures above ground. Deep down in the town far below the desert surface, the temperature is between 19℃ and 20℃ and life is cool.
Mary Deane and her husband Jim are among the lucky ones. They live in a home, built with money from the opals Jim has found. “Whenever people hear we live underground, they always imagine a dusty cave,” says Mary, “but they are amazed at my clean kitchen, our furniture and electrical appliances in here.”
However, not everything is perfect in Coober Pedy. Mary has a tiny garden that she is very proud of, but the grass is not real. Plant life is rare. Water is five times more expensive underground than it is overground. Recycling is a way of life, so Jim usually washes his car with bath water and they have a special system to reuse the water from the dishwasher and washing machine.
Even so, most families enjoy life in Coober Pedy. The children can make as much noise as they want and there are no complaints from the neighbors because the thick walls stop sounds from traveling. Adults enjoy the peace and quiet away from the world above.
