I find it difficult to V 与 I find it's difficult to v是否能用当主句 i find it difficult to I find it difficult to decide where to go.还是I find it 's dif 请问是I find it difficult to do sth还是I find it is difficult to I find it's difficult to learn English well.改同义句 I find it _ I find it difficult to finish it.和I find it isdifficult to f It is difficult to find find it difficult to do, I find it difficult to learn math well 为什么是“I find it difficult to learn English well?" I find it difficult to learn English well的复合句 I find it difficult to solve this problem .(改为复合句)
