I like to look at sth // I like to watch sth 对I like to see sth 为什么不对？你用了i like to 表示暂时的动作 喜欢去看。。。see看见，表状态。那 I like seeing sth 呢？I like seeing sth 也不对, 问题不是like to do 与like doing , 而是句子如果到此为止，意思只能表示动作， 只能是I like looking at ...应该是 i like to see /i like seeinghim always at home 加一个补语补充完整，就可以用see了那直接加sth呢比如I like to see the animalsI like to see the animals(看见动物怎样？不完整）不对 最好是i like to look at animals
