动词不定式通常为了表示目的或者是将来，所以我自己有一个解题方法就是如果空在句首（如题一），做状语，就直接把动词不定式翻译成 为了 带进去，如果逻辑没有错误一般就是正确答案。1_________the plan carefully,he rejected it A. to have considered B. having considered你不可能说为了仔细考虑这个问题，他拒绝了这个问题。所以这个是可以排除的。答案可以锁定为B再看这道题________this cake, you’ll need 2 eggs, 175 g sugar, and 175 g flour. A. Having made, B, Make C. To make D. Making 为了做这个蛋糕，这就对了。答案直接就是C第二题the research scientists often meet with problems_____new types of instruments for their solution.Ato requireBrequiring非谓语做定语，其实你也可以试一试。为了同样是翻译不通的，而应该是科学家经常遇见需要新类型的器具的问题。所以可以锁定B高中经常用不定式为定语的考点其实就是The play _________ next month will````` 这种类型的，用不定式表示将来你看到将来的时间，朝不定式奔过去就行。

offering和to offer都是主动，逻辑主语都是official letter区别在于the official letter to offer him it=fhe official letter which will offer him the jobthe official letter offering him it=fhe official letter which offers him the jobto offer表示将来，难道现在还没给这个职位？ John has really got the job 给出解释了offering就是说明，习惯性的，常态的，因为每封信函上都是offer a job to sb 人reserve a table ，所以table被动没问题，区别:reserved 表示被动完成，预定好了to be reserved 将来被动，等于还没这桌饭还没预订sat at the table 人已经上餐桌了
1.如果是to offer那么要么表明“目的是为了。。。”，要么表明这个动作没有发生，所以，从整个句子来看，是错误的。John已经得到了这份工作。offering 在这里是表示伴随，而且是主动，因为它的逻辑主语是“the letter”,"the letter "与“offer”之间的关系是主动的发出，所以用主动态。 2.还是上面一样，用了to do就表示“为了给客人预定”的意思了，这个在中文中可以，英语中不行，reserved for customs 是作为后置定语出现的，它省略的成分是“which was ”.
