首先请你确认一下第一题的答案,我觉得可能有问题.be used to是习惯于的意思而且to是介词后应接ving.选的话A或B应该都可以,都是过去常常的意思.
consider make一类的词用于被动要用带to的不定式的,并且哥伦布发现美洲大陆已经完成所以用不定式的完成时.
情态动词+have done表示对过去事情的推测.may的话表示可能性比较小,might则更小.
关于第四题应该没错,think直接加从句多表认为或想象的意思,think of的话可以指想到的意思,后面加that从句表内容.
至于为什么不选A,可以从词组的含义上去考虑.该词组强调结果而非过程,如果原句是think的话还可以考虑,否则C项更好些.
希望满意哦!
