It is known to us that computer users are being warned by industry experts to pay attention to secret codes which could be used to record their conversation.
E-mails, screen savers, and electronic greeting cards can carry a secret code which is able to turn on the computer’s microphone, make a recording, and forward it to someone else without the user’s knowledge.
In fact any attachments (附件) sent to a computer, whether it is a game of Space Invaders, or a moving picture, can possibly be used to spy (窥探).
Experts say people should always think twice about opening attachments because --- although not common --- bugging (窃听) by computer can and has been done.
Bill Lyons, head of the Internet Security Company Finjan, said, “People in the army have tested this and you can be sure, if people in general are aware of it, then computer hackers (黑客) are aware of it. The frightening thing is that there are tools on the Internet which people, using a simple search method, can find, and which will enable them to attach this dangerous code to simple attachments.”What is the advice given in the passage?
| A．Use secret codes to record other people’s conversation. |
| B．Be careful when opening an attachment. |
| C．Never open any attachments. |
| D．Never use secret codes. |
What worries the experts is that ___ .
| A．nobody seems to believe such things |
| B．nobody knows the danger of the code |
| C．tools can easily be used to tie dangerous codes to e-mails |
| D．effective ways can never be found to deal with the problem. |
Which of the following is TRUE according to the passage?
| A．A moving picture cannot be used to spy. |
| B．Electronic greeting cards cannot carry a secret code. |
| C．A secret code is used to destroy the computer system. |
| D．Any attachments sent to a computer may carry a secret code. |
Brooke Martin’s golden retriever(金毛猎犬) Kayla hated being left alone or separated. She would howl, pace, and chew on things. Brooke learned that other people had the same problem with their pets. She wondered: ―What if you could talk to your dog if you were gone?
Working with her father in their garage, the 16-year-old came up with several ideas. Finally, she invented a device that allowed pet owners to video chat with their pets! She calls the device iCPooch. ―The dog doesn’t have to answer the call,explains Brooke. ―It comes up immediately on the screen on their end. It’s a two-way audio and video—you can see and hear each other.With a click of a button you can even send the dog a treat!
Her invention has earned her a spot competing against nine other finalists in a young scientist competition for middle-school students. These finalists, selected based on their short video presentations, are working with mentors over the summer before heading to the final competition in St. Paul, Minn.
After Martin’s video put her among the 10 finalists in the Discovery Education 3M Young Scientist Challenge, she was paired with Delony Langer-Anderson, a product development scientist in 3M’s consumer health care division. ―I just lead her down the product development path,Langer-Anderson told Live Science. This path includes guidance on how to test the potential product, which combines a video chat device that answers immediately on the dog’s end with a dog treat device the owner can remotely activate.
One thing I have thought about a lot is, what happens if while the device is on the floor, what if your dog knocks it over, or scratches the screen? Martin said. She and Langer-Anderson discussed this, and Martin is now testing materials at a local dog shelter by taping them to the dog house floors to see how well they withstand sharp teeth and claws.
The finalists create models they can test, with the guidance from a mentor. Their projects include a fuel cell that transforms cut grass into electricity and an app that rewards drivers for not texting or calling. Langer-Anderson tries to help the students work through the scientific method, testing their hypothesis, in a determined way, ―so the kids don’t get buried in data.she said.Which of the following would be the best title of the text?

There was a little boy visiting his grandparents on their farm. He was given a slingshot（弹弓）to play with out in the woods. He practiced in the woods, but he could never hit the target. Getting a little discouraged, he headed back for dinner. As he was walking back he saw Grandma's pet duck.
Just out of impulse(冲动),he let the slingshot fly, hit the duck in the head and killed it. He was shocked! In a panic, he hid the dead duck in the wood, only to see his sister watching! Sally had seen it all, but she said nothing.
After lunch the next day Grandma said, "Sally, let's wash the dishes". But Sally said, "Grandma, Johnny told me he wanted to help in the kitchen. "Then she whispered to him, "Remember the duck?" So Johnny did the dishes. Every time Grandma asked Sally to do some housework, she will repeat the same story. After several days of Johnny doing both his work and Sally's, he finally couldn't stand it any longer. He came to Grandma and confessed that he had killed the duck.
Grandma gave him a hug and said, "Sweetheart, I know. You see, I was standing at the window and I saw the whole thing, but because I love you, I forgave you. I was just wondering how long you would let Sally make a slave of you. "

Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time – about eight hours after you wake up – your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.
In many parts of the world, people take naps(小睡) in the middle of the day. This is especially true in warmer climates(气候), where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from problems such as heart disease.
Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long. If you do not have enough time, try a short nap – even ten minutes of sleep can be helpful.Why do people feel sleepy in the early afternoon according to the text?

Many countries follow special customs when a child’s baby teeth fall out. Many of these customs tell stories about animals taking the teeth.
For example, Koreans have the custom of throwing the fallen tooth onto the roof of a house so that a magpie (喜鹊) can take the tooth away and bring a new tooth for the child. This custom is also followed by some other Asian countries, such as Japan and Vietnam.
Other countries, though, have tooth customs about other animals. In Mexico and Spain, for example, it is thought that a mouse takes a fallen tooth away and leaves some money. But in Mongolia, it is dogs that take children’s teeth away. Dogs are highly respected in Mongolian culture. It is believed that the new tooth will grow strong if the baby tooth is fed to a dog, so parents in Mongolia will put their children’s fallen teeth in a piece of meat and feed it to a dog.
In France and the USA, a child will put a fallen tooth under his or her pillow before going to bed. It is thought that in the early morning, when the child is still sleeping, the Tooth Fairy will take the tooth away and leave something else under the pillow. What she will leave is hard to know. It is said that in France the Tooth Fairy may leave some candies; however, in the United States, she may leave money.Koreans throw a tooth onto the roof of a house in order to __________.
