Dogs wag(摇摆) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found.
Researchers in Italy examined the tail wagging behaviour of 30 dogs, catching their responses to a range of stimuli(刺激物) with video camems. To conduct the study, they chose 15 male dogs and 15 female ones aged between one and six years. The dogs were all family pets whose owners had allowed them to take part in the experiment at Bari University. The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli. They were tested one at a time.
The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners —a positive experience— their tails wagged energetically to the right side. When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The appearance of a cat again caused a right-hand side wag, although with less intensity again. The appearance of a large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left. Researchers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli, they tended to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were not easily noticed without the aid of video, it was thought that the findings could help people judge the mood (心情) of dogs. Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that they were required to approach.The video cameras were used to catch the dogs’ response because______.
| A．The dogs wagged their tails in different directions when they were in different moods |
| B．they enabled the dogs’ owners to know about their dogs’ habit |
| C．It was easier to catch the dogs’ response change in tail wagging |

Every afternoon hundreds of thousands of youth fill Internet cafes, switch on a game console (游戏机), or otherwise sit down to enter fantasy worlds. I’m talking about video games. These games can be fun and exciting, but we need to look out when this pastime becomes an addiction.
Games are often quite exciting and dramatic, but they generally aren’t very intellectual. We don’t learn as much from them as we would only reading a book. Spending too much time playing them can take away our study time. We need to remember that we are students first. Nothing should ever get in the way of proper studying.
Video games can also be a bad effect on younger children who may be watching. Many video games are violent and the object in most of them is to kill the other player(s). This does not send the right message to the children who need to be told that violence is not acceptable and need to be taught how to deal with situations maturely. Even if we do need to sit down and play a violent video game, we need to make sure that it is not affect the younger people around us.
Playing a computer game in our spare time is not a bad thing. Games can be a great way to relax after studying, to connect to our friends, or just to help our creativity. However, games should not become the focus of our life. We need to make sure that laying games never interferes with our studies and that we aren’t thinking about them all day. If we ever find ourselves playing them too much, we need to break the addiction. If that happens, we need to step away from the computer or television screen and learn to spend our time more productively. The writer mainly tells the readers __________.

Electronic waste, or e-waste, refers to electronic products that are no longer usable. This can include TVs, cell phones and computers and other office electronics, electronic toys and videos machines. Today, the average turnover（更换）rate for a computer in the United States is every two years, according to the environmental group, Greenpeace.
The group's Dai Yun says e-waste is a global problem. "The electronic industry is one of the fastest growing industries in the world. The high speed of growth in this industry means more and more electronic products are being wasted and thrown away. If no one decides to retrieve the old products and process them properly, the electronic waste will sweep over the earth like the huge wave behind me and pollute the Earth seriously."
Greenpeace works out that 20 to 50 million tons of e-waste are produced globally each year. The components（部件）in many electronic products contain harmful chemicals that pollute ground water and the environment.
At present , the U.S. has no federal law for the disposal (处理) of e-waste although a few states have e-waste recycling programs in place, but there is no law. The U.S. exports much of its e-waste to third world countries, such as India and China, where workers took apart computers for valuable parts, hoping to sell them for money. But harmful wastes expert, Dr. Bakul Rao, says that's a dangerous practice. "From now on, the recyclers are not very educated. All they know is they can retrieve copper or gold out of it. So, the easiest way to do that is leach (过滤) it out in an acid or burn it off to retrieve it. So, that's where they don't know how to deal with it, neither do they have any health systems in place. So, their exposure is more." Which of the following is most likely not to be a form of e-waste?
| A．A mobile phone | B．A radio | C．An e-bike | D．A table |

| C．The way uneducated workers deal with old computers does great harm to the environment as well as to their own health. |
| D．More and more electronic waste is being wasted and thrown away mainly because of |
people's bad habits.What is the purpose of writing the passage?
| A．To attract more people's attention to e-waste. |
| B．To call on people not to throw away e-waste anywhere. |
| C．To tell people what e-waste is and how to deal with it well. |
