02、点评
综合写作：
登革热会通过蚊子进行传播，科学家就通过对蚊子进行基因改造，然后再把基因改造后的蚊子投放进入现实世界。这样产生的后代就都死掉了。有人就批评这种基因改造后的蚊子会有问题。
第一、其他的蚊子有可能带毒更多，致病性更强。基因改造的蚊子虽然都死了，但是致病性更强的蚊子有可能增多了，那麻烦就更大了。
第二、基因改造后的蚊子叮人之后会带来大麻烦，因为基因改造会使得蛋白质死亡，而如果叮人之后，人的蛋白质也死亡，那麻烦就大了。
第三、之前有基因改造过的植物，造成蝴蝶数量大幅的减少。这时引入基因改造的蚊子会带来什么后果，说不定。
听力：
第一、科学家已经做过相关的研究，就是亚洲老虎蚊带毒性更强。而当基因修改的蚊子被放入到自然界当中之后，基因修改的蚊子数量减少了，但是亚洲老虎蚊的数量stay same，亚洲老虎蚊并没有大规模上涨。
第二、科学家只是对雄性蚊子做了基因修改，但是雄性蚊子不会叮人，只有雌性蚊子叮人，所以经过基因改造雄性蚊子不会影响人类。
第三、基因改造所造成的蝴蝶影响只是一个孤立的案例，并没有其他类似的案例。现在是在用杀虫剂来对蚊子进行基因改造，这对环境不好。但是如果用新方法做基因改造，那就对环境没影响了。
独立写作：
解题思路：historical sites
First, by means of visiting historical sites, like local memorial hall of the fame in history, or the relics of a historical event, tourists can have access most effectively to get immersed in the local history and know better about the city directly. 了解一个城市最有效的方式是去聆听这座城市的历史，感受它的文化和内涵。虽然停留的时间比较短暂，没有办法每个历史历史遗迹景点都去一一品读，但是这个方法是最直观的感受这座城市的。+具体论证。
Second, you can find something unique about the city you are visiting by spending your majority of travelling time in historical sites. It is because some “local” industries, such as shops and restaurants, are commercialized similarly and you cannot find anything new and special about the city.很多所谓的“当地的”商店和餐厅，都被严重地商业化，且和其他的很多地方很相似，你没有办法通过这两处找到这个城市的任何特色的东西。(进行段内对比)
让步段：Admittedly, some visitors contend that it is impossible to know the city very well only by visiting their local historical sites because usually it takes plenty of time to visit these places, but the visiting time is limited. Thus, in this way, it is rush and shallow to know the city in such a short time. However, we can google the most recommended historical site by the internet and have a thorough plan before we visit. Also, in consideration of time shortage, we can ask a tour guide who is proficient in local history to explain the knowledge to us.
