physician and psychologists. The phrase "substance abuse" is often used in-          S4.______
stead of "drug abusive" to make clear that substances such as alcohol and to-        S5.______
bacco can be just as harmfully used as heroin and cocaine. We live in a society      S6.______

quite a headache, some wine to be sociable, coffee to get going in the morning,      S8.______

taken in excess will produce positive effects such as poisoning or intense per-      S10.______
petual distortions. Repeated use of a substance can also lead to physical addic-
tion or substance dependence.

答案mistaken→mistakenly
解析 用词不当。此句中有believe作动词，mistaken是形容词，表示“错误的”，这里应该用副词来修饰动词。
