(A) are those that boys experience
(B) what boys experience
(C) boys' experience would
(D) boys' stress patterns do
(E) stress patterns of boys
答案解析：
(A) 正确, those指代前面出现的patterns of stress, that从句修饰those表达清晰;补出助动词are使句子意思表达清晰无歧意; patterns of stress that girl experience和those that boys experience结构对称.
(B) 比较对象不对应,比较的前者是patterns,后者是what boys experience.
(C) 比较对象不对应,比较的前者是patterns,后者是boy’s experience; would不能代替are,
(D) do应该改为are
(E) 意思表达不清patterns of boys表达太模糊.缺乏助动词are意思表达模糊,可以理解为,： …are more likely to result in depression than result in stress patterns of boys;patterns of stress that girls experience与stress patterns of boys表达方式上不平行。

(D) In cooking, small quantities of spices are used, whereas in medicinal usage spices are taken
(E) In cooking, the usage of spices is in small quantities, whereas in medicinal usage they are taken
答案解析：
(A) unlike后面应该接名词
(B) in using短语既可以修饰前一个分句,又可以修饰后一个分句,造成修饰歧意.
(C) unlike后面应该接名词
(D) 正确, 用whereas表示对比关系前后句子在形式上不需要完全对等, 修饰成分紧靠修饰对象,避免了修饰歧意
(E) the usage of spices is in small quantities表达笨拙;they指代不清,可能指代quantities或者spices.
