托福听力中考生做不对题目很多时候并不是因为大家没能理解听力文章的内容，而是压根没意识到出题点在哪里所以完全没记住本该记住的关键信息。其实托福听力虽然信息量很大，但对于哪些可能涉及出题点关键信息都是会提前进行提示的，而这些提示用的信号词大家就需要及时发现了。下面小编就来为考生详细介绍。
　　 托福听力关键信息信号词：简单信号词这一类信号词是属于简单的信号词，比如 "Okay", "Well", "Now", "But", and "So" 这些，具体来说：
　　1. Okay 和 Now 一般用在不同话题或是关键信息之间的过度，比如：
　　But all the other elements, like the location or characters, might be modified for each audience. Okay. So what about fairy tales?
　　Take the Grand Canyon for instance. Now, we geologists thought we had a pretty good idea of how the Grand Canyon in the southwestern United States was formed.
　　2. Well 一般用在回答一个问题之前，所以听到这个词后面往往就是解释，比如：
　　Um … and it was basically because of Uranium-Lead Dating. Why? Well, as everyone in this class should know, we usually look at the grain type within sandstone, meaning the actual particles in the sandstone, to determine where it came from. "But" and "So" are usually followed by a key point.
　　3. But 和 So 后面一般会紧跟一个关键信息点。
