3x(x－2)＝2(x－2)； 答案：(3x－2)(x－2)＝0， ∴x1＝，x2＝2.  All over the world,children in hospital are getting a new kind of medicine: . Lucy works for Theodora Children s Trust. She is one of many clown (小丑) doctors who bring a smile to the faces of sick children.   I'm a clown doctor. I call myself Dr LooLoo. I spend two days a week in children’s hospitals with my friend Dr Chequers. We make firnny faces,tell jokes,and do magic tricks. As I walk into a ward （病房) , I shake hands with the kids and sing songs. We take special balloons to make “balloon animals” and tell firnny stories about them. We often meet kids who look really sick at first,then we go back the next week and they,re running about shouting “Hi there,Dr LooLoo!Hi Dr Chequers!”   I’m naturally a very cheerful person. I’ve always been a clown. In fact my father is a clown and I started working with him when I was eight years old. I knew it was just the job for me. I became a clown doctor because I think it's a great way to cheer up sick children in hospital.   At lunchtime we eat in the hospital dining hall and that’s really useftil because we meet the nurses and doctors. They tell us about some kids who they think will benefit(获益) from a down doctor's visit. For example,if a child is afraid,perhaps he's being given an injection(注射) or some medicine,we’11 visit him and take his attention,then the nurse can do her job.   At about six o’clock,Dr Chequers and I change our clothes. We’re very tired. On weekends we are often asked to take part in events to raise money for Theodora Children's Trust. Being a clown doctor is very tiring,but it makes the worries of everyday life,seem small. All in all,I feel lucky to do this job.根据材料内容选择最佳答案。() 56.
