so ...that...的用法问题

1 The weather was___wet___the clothes were not very dry

A so that B such that C as as C so as

我选A，但答案选D。为什么呢？

2 Student brave enough to take the advanture course will certainly learn a lot of useful skils.

分析下句子的成分

请高手帮忙解释

1. D

so……as中as必须在从句中担任成分（主语、宾语等），而从句就是我们熟悉的定语从句咯。
so……that中的that 不能在从句中担任成分，只是单纯的先行词，从句也就不算定语从句了。
简单的说，要判断使用哪一个，可以看先行词在从句中是否担任成分

2. "brave enough to take the advanture course"作后置定语修饰student 意思为：很勇敢而参加了冒险课程的学生

will learn 是将来时

certainly 副词修饰动词learn

"a lot of useful skills" 是宾语

我也认为是A

Student /brave enough to take the advanture course /will certainly learn a lot of useful skils.

足够勇敢选择冒险课程的学生肯定会学习很多有用的技巧
