21题，这里需要理解上下文的含义。这一整句话仍然是在说明公司进行planning的原因。正是因为相似的模式会在市场上出现，所以公司才需要进行计划。选patterns是最符合原义的。
22题，很明显，这里填入的词是表示批准、通过之类的，是指年前三个月完整的计划就会被通过。从中文意思上看，A、B、C三个词都是符合的。具体看英文解释对几个词的用法进行区分。
approval：when a plan, decision, or person is officially accepted批准，正式的
eg:The president has already given his approval to the plan.
permission：when someone is officially allowed to do something允许，也是正式的
eg:You must ask permission before taking any photographs inside the church.
consent：permission to do something不那么正式的允许
eg:He took the car without the owner's consent.
这一题是讲的计划被批准或者通过，所以用approval。
