The public discussion that the incident caused started on the Internet. However, when it came to the media's attention, it quickly became a major topic in the education circles. The reactions so far suggest that the focus of the debate has been on one question: whom to blame? Teachers who are anxious to defend their professional dignity have tried to put the blame on the students. They mentioned their right to privacy )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 between the teacher and students in classroom has been changed. Question: The author's purpose in writing this passage is to _ . - improve the teachers' way of teaching - stress the using of PDA in the classroom - change the students' behavior in the classroom - discuss the potential problems of educational system

Laws are often not enforced , or are enforced half-heartedly. The law clearly prohibits storage of dangerous goods and chemicals within a certain radius of residential areas, and there must be strict adherence to rules on storage and transportation, etc. The fact that this accident occurred so close to residential areas, resulting in devastating damage to homes and serious injuries to residents, shows that the law was not strictly enforced. Whoever approved the siting of that logistic plant in that particular area has a lot to answer for. Often, officials come to take action only after lives are lost. Another case in point is the unfortunate death of a young mother in the escalator accident in a shopping mall recently. Problems with elevators and escalators have been around for ages, and residents have made countless complaints, but to no avail. After the accident, city officials fan out all over the country checking on escalators for faults, and many escalators have been shut down for repairs. This kind of action is a kneejerk reaction to a serious disaster! There are many disasters waiting to happen. And all are due to weak or non-existent enforcement. For instance, it's well known that many residents add an extra floor to the roof-top of their apartment bocks, endangering the safety of the block, while others dig into their ground floor units to create an extra basement living area, hacking away concrete slabs and cutting steel bars which are the basic foundation of the building, seriously jeodardizing its safety. Neighbors complain, city officials come round and leave, saying they can't do anything as the owner wouldn't open his door for an inspection! They would often leave a note on the owner's door telling him to stop construction, but true to form, the owner just ignores it. This is the kind of enforcement we see so often in China. What is urgently needed in China is a complete overhaul of the... Question: In what purpose do some residents dig into their ground floor units according to the passage ? - To follow their neighbors. - To create an extra basement living area. - To protect themselves safe. - To add an extra floor to the roof-top of their apartment bocks.
To create an extra basement living area.

Armed with only a chisel, a chainsaw and a hammer, the 32-year-old moved his family to a hillside in Wales and started digging. The result is a wooden eco-home - constructed in four months and costing just PS3,000 - which would look perfectly at ease alongside the Hobbit houses in The Lord Of The Rings. Mr Dale, who has no experience in carpentry or architecture, created his sustainable family home using scrap wood for floors, materials scavenged from skips and by diverting water from a nearby spring. He said: "Being your own have-a-go architect is a lot of fun and allows you to create and enjoy something which is part of yourself and the land rather than, at worst, a mass-produced box designed for maximum profit and the convenience of the construction industry. Building from natural materials does away with producers' profits and the cocktail of carcinogenic poisons that fill most modern buildings. The family struck lucky searching for a site for their dream project. In return for looking after the area, the owner of the woods gave them their plot for free. After digging into the hillside, Mr Dale - with the help of his father-in-law, a builder - first constructed the building's timber frame. The roof, which came next, has a layer of straw bales for insulation and is covered with sheets of plastic to make it waterproof. Finally it is covered with a layer of earth, which ensures the house blends perfectly into its surroundings. Once the outer shell was complete, the family made an interior wall from straw bales stacked on dry-stone walling and staked together with hazel sticks. As well as being made from sustainable material the Hobbit house, as it is dubbed by locals, has lime plaster on its walls instead of cement, a compost toilet, a fridge cooled by air from beneath the foundations and solar panels for power. Question: It can be inferred from the passage that the Hobbit houses _ - don't exist in the real world at all - belong to the lord of The Kings. - lie in a lonely area of Wales - are a kind of environmental friendly houses created by Simon Dale
