朗阁讲师林森点评

综合写作：

阅读：存在三方面的挑战

1. terrain and landscape 会使建造变得艰难；


2. lack of workers；

3. benefits 不足以cover high cost。

听力：否定

1.  有devices 来帮助dig 和remove roots, 可以include labor， 同时他们在冬天才在这片区域工作，因为这个时候mosquito in wetland 比较less active；


2.  有immigrants，他们需要工作，可以把这些艰巨的工作给他们；

3.  正是因为interior区域不便通行，那里才没有人，建造了之后那里运输货物也会比较便利。相比于原来100刀的成本，现在只要10刀就可以从水路上从东运到西，便宜了很多。

 

独立写作：

本题是比较常规的利弊分析题，以下是给出的参考：

解题思路：赞同立场

1. For one thing, staying mentally active can help prevent mental disease in populations of older people. （保持不断学习能够预防老年人的脑部疾病的发生。）When you keep your brain engaged, you can build reinforce the connections between brain cells or perhaps even create new ones. This is possibly why mental disease occurs less in populations with higher levels of education. （学习的过程可以加强脑细胞间的活动，甚至创造出新的脑细胞，从而保证了脑部的正常运作。）

2. For another thing, continuing to acquire new knowledge will keep elderly individuals emotionally present and connected to the world. （不断学习同时能够帮助老年人跟上世界的发展。）Changes in society can seem to come swiftly and without warning, thus, if they stop trying to learn to use new technologies or grasp new ways of interacting, they will become out of touch with those around them.（世界改变非常迅速，如果不学新的东西就会很快被淘汰。）

3. 让步段：　Granted, non-stop learning can be tiring and time consuming.（这是一个让步段，简单说明不停的学习的确是比较花费时间和精力的过程，再进行削弱。）

 

考试预测

本题是利弊分析类题型，希望同学们在备考过程中予以重视。

1. It is more important for the government to spend money on building new houses than preserving the historic or traditional buildings and homes.

2. Technology that is designed to make people’s life simpler actually makes it more complicated.
