1.To be convincing:to provide powerful support for a belief and to overcome doubts.
to overcome中的to为什么不省略?
2.I told her to leave us alone and not to interfere in our problems.
否定的并列不定式是不是不用省to?(not to interfere )
请问 here are 是存在句吗? 还是说here是个副词,它的位置可以移动?比如:Here are your cigarettes in the refrigerator. 是否可以写作:Your cigarettes are here in the refrigerator.There are your cigarettes in the refrigerator.
