您好，几个回答，让你纠结了吧，综合起来，给你一个满意的解释：1. at 改为in (in this way 以这种方式)2. difficulty 改为difficult ( find it + 形容词 to do sth. ＂发现做某事...")3, explain 后面加to. (explain to sb. 向某人解释）4. the改为The (句首单词大写）5. to 后面加上be (这里是被动语态） 注：第3题不知道你是否why后面漏打了个you, 按理说这里的you是不能省略的，(why 后面引导的宾语从句，why 后面必须要有主语．）可是衡量下来这道题最大的问题还是explain的用法它用错了． ...
