拖垮:I"m a little bit fat

I"m a little bit fat 复数中 a+bi "i"是指什么？ "I was a little bit spoiled by mymother"中的a little bit 是什么结构？？ I Say A Little Prayer 求所有满足IabI+Ia+bI=1 的整数对(a,b) "I"为绝对值 I need a little help, about GRE i say a little prayer for you 同义词转换 I have a little dog. when I was just a little girl 改错(每句一处错):I'm very thirsty, but there is a little water in the bottle
