It took me two years to figure out this rule of grammar,and it took me half an hour to translate these two sentences into English. He is going to have his tooth pulled out this afternoon.However,I told him not to ask for a leave,for there is an more important task to finish.
1 it took me two years to get clear about the grammar, and yesterday, i spend half an hour to translate these two sentences into English. 2 he needs to go for a dental extraction in the afternoon, but i suggest him not to ask for a leave in this afternoon since he has something more important to be done.
