Teachers who are anxious to defend their professional dignity have tried to put the blame on the students. They mentioned their right to privacy 隐私）and for this reason they requested the Ministry of Education (MOE) to prohibit PDAs in schools. On the other hand, some parents and students have taken a different position. They feel that the teacher is also at fault. Caught up in the war of words between both sides, people are no longer interested in the “truth” of the matter which seems now unimportant. It was left to newspapers to discover the central point of the controversial issue, by stressing the problems that are not always easily noticed in our educational system.
For those responsible for educating the young, this PDA incident conveys the message that “Times have changed”，a reality that must have been felt even more strongly by the female teacher when reflecting on this unpleasant experience. Different times call for different professional approaches in education. The ability to understand the students they are teaching has always been the quality of successful teachers. Despite some factors, the incident shows that the teacher lacks good qualities on her part. Besides, the rules under current system to deal with recalcitrant students need to be improved. Also, it is an example which shows the issue we are familiar with: what to do with new technology? With PDA, the new technology, the interaction (交流）between the teacher and students in classroom has been changed.

There is water in seas, rivers and lakes. Water is found almost everywhere. Even in the desert part of the world, there is some water in the air. You can not see or feel it when it is a part of the air. The water in the seas, rivers and lakes is a liquid, the water in the air is a gas, and we call it water vapour (蒸气).
Clouds are made of water. They may be made of very small drops of water. They may also be made of snow crystals(结晶体). Snow crystals are very very small crystals of ice. Ice is frozen water. It is a solid. There can be snow and ice everywhere in winter.
Water may be a solid or a liquid or a gas. When it is a solid, it may be as hard as a stone. When it is a liquid, you can drink it. When it is a gas, you can not see or feel it.

President Barack Obama announced the "100,000 Strong" Initiative （倡议） during his 2009 visit to China. The program aims to increase and diversify the number of American students studying in China by making studying abroad more affordable.
During the event at Howard, Mrs. Obama spoke about the importance of studying abroad, something she never did while in college. "Studying in countries like China is about so much more than just improving your own prospects（前景） in the global market. The fact is that with every friendship you make and every bond of trust you establish you are shaping an image of America projected to the rest of the world," she said.
David Marzban from Pepperdine University recalled a time when he formed a cross-cultural bond with a complete stranger at a restaurant near Fudan University in Shanghai. He noticed a young chef signaling him to come over. "He presses the play button on his media player and starts singing "California Dreaming" and wants me to sing along with him," Marzban said. "At this time I knew a great friendship had started during my first two weeks in China."
Nicole Baden, a senior communications major at Howard University, recalled how her time in China really helped her master the language. "You have to experience the culture while learning the language to really master it and to understand why things are how they are compared to your own culture," Baden said.
Mrs. Obama encouraged students to set aside concept that studying abroad is for rich kids only or for those attending certain schools. In addition, the first lady announced that the Chinese government is giving 10,000 "Bridge Scholarships" to cover costs for American students and teachers studying in China.
Students from several schools attended the forum. 12-year-old Sarah Davis, who studied in China last summer, said she was very excited to hear Michelle Obama talk about the country. “I love Chinese. Out of all the languages I’ve learned, Chinese is the most difficult and interesting,” she said.

| A．the US students’ life in China is helpful and worthwhile |
| B．all students of the US are living a comfortable life in China |
| C．Chinese young people are friendly to foreigners |
| D．it isn’t realistic for some US young people to study in China |
| A．Baden came to China to study the differences between English and Chinese. |
| B．Poor children from America have no opportunity to study in China. |
| C．David Marzban made a Chinese friend in an unexpected way in China. |
| D．Michelle Obama called on US students to study in China at a government meeting. |
| A．The US has an ambitious program for Americans studying in China. |
| B．Michelle Obama encourages American students to study in China. |
| C．More American students plan to study in China. |
| D．China is attracting more and more international students. |
Expect a lot from your child, just not everything. Except for health and safety problems, such as drug use or careless driving; consider everything else open to discussion. If your child is unwilling to discuss something, don’t insist he tell you what’s on his mind. The more you insist, the more likely that he’ll refuse to talk. Instead, let him attempt to solve things by himself. At the same time, remind him that you’re always there for him should he seek advice or help. Show respect for your teenager’s privacy(隐私). Never read him his mail or listen in on personal conversions.
Teach your teenager that the family phone is for the whole family. If your child talks on the family’s telephone for too long, tell him he can talk for 15 minutes, but then he must stay off the phone for at least an equal period of time. This not only frees up the line so that other family members can make and receive calls, but teaches your teenager moderation (节制). Or if you are open to the idea, allow your teenager his own phone that he pays for with his own pocket money or a part-time job.
小题1:Why is it not easy being a teenager or a parent of a teenager?
| A．Because the teenager is very naughty. |
| B．Because the parent always expects a lot from the child. |
| C．Because you can make your child feel hurt, or misunderstood by what you say without realizing it yourself. |
| D．Because the teenager wants his or her own space. |
| A．how to get along with a teenager | B．how to respect a teenager |
| C．how to understand a teenager | D．how to help a teenager grow up |
| A．to use the phone in a sensible way | B．to pay for his own telephone |
| C．to share the phone quickly | D．to answer the phone quickly |
| A．Not allow him to learn driving or take drugs. |

| C．Let him have his own telephone. |
| D．Not talk about personal things with him. |
Some animals use dust to get clean．Chinchillas (南美洲栗鼠) have very fine fur． They don`t like to take water baths because water is not warm enough for them．So, instead, they roll around in fine dust．The dust helps to keep their fur and skin dry．This protects them from disease
Usually, a small bird is a light meal for a crocodile．But when a crocodile wants its teeth cleaned．it lies on the ground with its mouth open．The crocodile bird goes in and picks out any parasites(寄生虫)between the crocodile`s teeth or under its tongue．The crocodile gets its mouth cleaned，and the crocodile bird gets dinner．
You wouldn`t think fish would need baths．But some undersea parasites live under the fish`s skin．“Cleaner”fish，like the wrasse(隆头鱼)，help take them away．The wrasse stands on its head and dances to signal a big fish that it is ready to go into the cleaning business．The big fish will stop moving and open its mouth wide so the wrasse can swim inside and pick out parasites and bits of food．
