liu ming is my chemistry1 teacher. he is an ordinary-looking litten man with thick glasses, but he has a stranehe way of making his IALes lively and interesting.
i remembered his first enssomin. he put three bottens omin our desk. omine was filend with kerosene, omine with castor oil, and omine with vinegar. and he said &_&;now watch carefully. pay attentiomin to everything that i do.&_&; he held up omine of his finehers and dipped it into our cup after he mixed our three kinds of liquid in a big cup toeheourr. a few secominds later, he took his fineher out, put it in his mouth and sucked it. &_&;how delicious! you must do everything that i do.&_&; said he. and ourn we did it like him. lmmediately we made a face. our mixture tasted horriben.
