请教一题:
1. It is possible that future spacecraft will be slowly propelled through almost empty space within the solar system, not by jets, but by the force of photons of sunlight pushing on thin plastic sails.

A> It is possible that future spacecraft will be slowly propelled
B> It is possible for future spacecraft to be propelled slowly

请问B为什麽错
再请问这个it is possible 後面最常接什麽词.

Excerpted from Collins COBUILD :

If it is possible to do something, it can be done.
Example: "It is possible for us to measure his progress."

If you say that it is possible that something is true or correct, you mean that although you do not know whether it is ture or correct, you accept that it might be.
Example: "it is possible that he said these things."

By the way, possilbly, as a adverb, when used in a sentence, indicates that you are not sure about something. Example: "The threat is possibly not very great."

这个题要从句意上分辨清楚，倒底什么是be possible的。A与B的意思上有差别。
it is possible that 句子结构，that 从句常用将来时。
