2答案E，根据空白处前面的It all comes down to dopamine和后面的It has many important roles: influencing memory, attention and how we learn可知，本句应该是对多巴胺的解释，故选E。

3答案A，空白处后面的内容都是对本句进行的解释。因而本题的答案应该是主题句，故选A。

4答案B，本句It is like a cup overflowing with water是对your brain will start to overload on dopamine 的解释，故选B。

5答案D,根据空白处后面的But don't fear, there is some good news.，说明空白处句子的内容应该是不怎么好的内容。而选项D又是对…people who slowly got back to an even balance of dopamine scored 8 percent lower.的解释，故选D。
