I. what 和 which 的用法区别
What 表示“什么，什么样的”。让你在没有任何范围的情况下来选择。例如：
What do you want? 你想要什么？（没有任何范围，由你来要。）
What do you want to eat? 你想要吃什么？（凡是能吃的，由你来要。）
What do you want to do? 你想干什么？ （只要你能干的，由你来定。）
which 表示 “哪个，哪些”。 让你在一定的范围里来选择；也就是说，在这几个中，你
要“哪一个或哪些个”。例如：
Which book do you like? 你喜欢哪本书？（只限于书的范围内，别的不在此内。）
Which apple do you want to eat? 你想吃哪一个苹果？（你只能在苹果的范围内来选择。）
Which of these two computers do you prefer? 这边两台电脑你选，更喜欢哪一台？（这回
的范围更小，只有从两个中选其一。）
II．描述情感
描述感情常用动词 feel 。经常用 How do you feel? 和 How are you feeling ？来询问对
方的“感觉”和“感受”。例如：
How do you feel today? I feel terrible. 你今天觉得怎样？ 我觉得很难受。
How are you feeling now? I feel much better. 你现在觉得怎样？ 好多了。
feel + 形容词
I feel happy. 我觉得高兴。
I feel weak. 我觉得虚弱。
I feel uncomfortable. 我觉得不舒服。
I feel tired. 我觉得疲劳。
I feel bored. 我觉得厌烦
I feel interested. 我觉得有趣。
I feel worried. 我觉得焦虑。
I feel cold. 我觉得冷。
I feel hungry. 我觉得饿。
I feel very well. 我觉得很好。
I feel terrible ill. 我觉得很难受。
I feel depressed. 我觉得沮丧。
I feel lucky. 我觉得幸运。
这当中有些词是由动词后加上 –ing 构成，有些是由动词加上 –ed 构成。在这里都用作
形容词，作表语。-ing 形式表明主语的特征；-ed 形式表明主语的状态。
