44. 标准答案：The W.H.O. says this situation raises concerns about the quality of treatments and the lack of professional supervision
听音关键：W.H.O. says，this situation raises concerns，quality of treatments，lack of professional supervision
答案重构：The W.H.O. says the situation makes people worry about the quality of treatments, and more professional supervision may be needed
画龙点睛：原词听写时，须注意quality of treatments和lack of professional supervision是concerns about的宾语。此外要注意单复数、时态一致。
45. 标准答案：the W.H.O. supports the use of traditional medicines when they have been shown to help and to have few risks
听音关键：the W.H.O.，supports，traditional medicines，shown to help and to have few risks
答案重构：the W.H.O. supports the use of traditional medicines when they have proved helpful and safe
画龙点睛：原词听写时，须注意supports，medicines，few risks等词的形式。
46. 标准答案：governments can also use the guidelines to create media campaigns about the issue
听音关键：governments，guidelines，create media campaigns about the issue
答案重构：governments can also use the guidelines, and try to inform the public of the issue through the media
画龙点睛：governments和guidelines在短文中均有出现，不会太难。campaign则是一个非常容易拼写错误的词，而且一时之间很难找到它的同义替换表达，需要平时留意。
