选C.
AD的意思是：的确是这样
BC的意思是：他也那样
题目翻译过来是：如果你明天早上去公园的话 接下去,应该是说：他也去.所以选BC之间一个.但是tomorrow morning 明天早上是将来的时间,所以用will,选C.look， look like ，seem like后接that 从句吗详细点说 它们的区别seem 和 look 后可加that 从句。look like 和 seem like 后不可加that从句seem似乎look看起来 seem like仿佛…似的She seems like a reasonable person.她看来是个通情达理的人。可能是也可能不是，给人感觉上像look like看起来与(某人或某物)相像〔相似〕He looks like a scholar.他看上去像个学者。表面看起来像It-- that he has been ill for a long time 为什么选择A呢 Aseems B looksClookslike Dseems likeIt-- that he has been ill for a long time 为什么选择A呢 Aseems B looksClookslike Dseems like这句话是个虚拟语句。选A，对现在的虚拟。B不对，应该是looks as ifC不对，应该是looks like as ifD不对，应该是seems like as if不是说look后面可以加that从句吗怎么又是looks as if了如果要用that的话，应该是这样：It looks that he is ill.而不是had been ill.
