回答：1，这是比较固定的believe的用法。提问是说你觉得会下雨么？不是问你相不相信。回答是我觉得不会的。一般都这样表达，里都是的。记住就可以了。但是think不是这样回答的。要说i don't think so.2，offer是指提供，也指提供的东西。比如找工作的时候，用人单位要你了，就会给你发出一份信函，这份东西就是offer.意思是单位向你提供一个工作职位。这里turn down his offer是拒绝他提供的东西的意思。这句话是说我知道自己不能从他这样的人那里接受任何东西但是仍然无法拒绝他这次的帮助（提供的东西）这道题的干扰项是suggestion，意思上也讲得通，但是因为有前文说他such a person，而且，一般accept的都是offer,而非suggestion3,问题是固定搭配：do u mind my doing so?你介意我做什么么？回答说不介意就说,no,of course not~当然不介意。一般即使介意，也不会说yes，而是直接说为什么介意；i am sorry that my fried will be here.4,envy是vt,妒忌的意思。我多妒忌你有这么好的运气阿~！ h.5，翻译疑问句的句末构成方式：与前面部分句式相反，而非与意义相反。前面是否定意义的unusual,但是句式是肯定式的，那么用否定形式的疑问。6,plenty of 充足的，足够的。b,基本不这么说，c\d都是用于不可数的。7,虚拟语气用倒装。意思是：如果医生不及时手术，这男孩就要死了。一般这种题目这么做：看题目和选项后明白是虚拟语气了，然后把正常语序写出来，选择那个倒装的就对了。（动词提到前面的那个）
