Others think that it is always better to have a teacher. Which do you prefer? Use specific reasons to develop your essay. Whether we need a teacher or not depends on circumstances. The relationship between a teacher and a new subject is somewhat similar to that between a tour guide and an unknown city. When we come to an unknown city for the first time, we definitely need a tour guide. We might have a detailed map, but it is unlikely functional – it isn't surprised that we can hardly interpret those mysterious symbols. Likewise, when we are beginners, it is wise to learn with teachers. They can tell us where to begin with, what we should do, and which reference we should choose. When we confront difficulties, we can ask them for help, and their advices will always be tremendously helpful. With teachers' assistance, we might learn easier, faster, and more interestingly. After a period of time, we have learned a lot. We now know the city pretty well, even though there still are many places we haven't been. It doesn't matter. Now that we are able to recognize those mysterious symbols on the map, what we need perhaps is not a tour guide but a more detailed map. Similarly, we need richer references for learning. Yes, there are still many fields unexplored; they are, nevertheless, no longer puzzling. The task is simple: we will explore them one by one, little by little. If we are working on a certain skill, practice more; if we are preparing a test, practice more; whatever we are learning, just remember, like people always say, practice makes perfect. After another period of time, we might have become others' tour guide, but we still want to know more. We want to know which restaurant is the most decent, which bookstore is the most professional, which coffee shop is the most classical. Even the most comprehensive map doesn't have adequate information. We again need experts. In learning, it's much the same. We need experts to consult for specific problems. Furthermore, the most beneficial merit of consulting experts is that we can not merely refer to them but even discuss with them in depth. As is often the case, a solution for a complex matter is not waiting for us right there and then, sometimes it comes out of inspirations of discussion. In short, having a good teacher is always better than having none, but the importance of a teacher varies from period to period, from stage to stage. [400 Words] 21. In general, people are living longer now. Discuss the causes of this phenomenon. Among various factors that contribute to today's longevity of people are three most obvious ones: the improvement of food conditions, the development of modern medical technology, and finally current stability of economy in our country. Food conditions are better than before and are still being developed with a rapid pace. First of all, foods are more hygienic. People today drink untainted mineral water, sterilized skim milk, which are cheaply supplied in supermarkets. Furthermore, foods are more nutrient. Not to mention various carefully designed nutrient products, people can just ignore the possibility of being dystrophic, in that they can keep nutrient balance by simply taking a cheap pill of vitamin compound every day. Another essential improvement that contributes to people's longevity is swiftly developing medical technology. Development of modern technology has always been amazing. Certain diseases such as tuberculosis, pneumonia, and dysentery are now easy to remedy with low expenses, but in the past, they are all probably lethal ones. The dental technology seems developed little except its exorbitantly charged bill, yet the simplest technology contributes to people's longevity most. It is not difficult to imagine that if an individual who lived in the past got a toothache, without certain dental care which is common today, he was certainly in an awful prospect: he might even die of a toothache! Current societal and economic stabilization is also a very indispensable factor. People have less pressure in a more stable society, the less pressure they suffer, the healthier they are. Today's ideal stabilization even provides people an opportunity to secure their future – buy insurances. Various types of insurances are readily available, which make people feel safe, and have to a large extent reduced people' anxieties, and therefore indirectly contribute significantly to longevity of people.

If my friend Joey wants to move to Beijing, I think she will definitely like this greatest city in our country, even though she might find something she dislikes. The weather might be one thing that she dislikes. The weather in Beijing is characterized by dry climate and it is much windy and dusty than that of Guangzhou city. Joey is very sensitive about her skin, so she will definitely hate dusty winds in Beijing. Moreover, Beijing's winter is far too much colder than that of Guangzhou, it might take Joey, as many other people came from the South, a very long time to get accustomed to. Nevertheless, she might well enjoy winter in the North, since she has never seen snowflakes in reality. I remembered the shining of yearning and eager in her eyes when I once told her what winters in the North look like. She might be always irritated by heavy traffic in Beijing, though taxis in Beijing cost much less than in Guangzhou. When I was in Guangzhou, seldom was I trapped by traffic jams. It must be ridiculous for her to have spent more than two hours and still didn't arrive at the destination which is merely 10-kilometer away. And the most ludicrous thing is, even if you possess a private car, it is more likely to be useless, for parking lots are always crowded, which means more time is to be wasted. One good news for her is that the bus system and subway system in Beijing are well developed and more convenient, and an even more delight one is that she won't have to bear that odor of bromhidrosis owing to burning weather as she once experienced in buses of Guangzhou. What she will definitely love is the cultural ethos of the city. Beijing has a history probably longer than any other big city in China. To visit all historical landscapes in Beijing, she will need at least three years, no kidding! Beijing has the most famous and excellent universities, the largest libraries, the richest museums, yet most important of all, her best friend! Amazingly, in this aged city, people are sometimes more international. Joey is especially fond of art, and Beijing is the right place for her, which is much frequented for concerts of international singers or other musicians, and she will even be able to attend CuiJian's private concert in a coffee shop on a rainy autumn weekend.
