小杨是个爱动脑、爱动手的学生，课外时间喜欢做一些小实验．在他学习完“植物的生殖方式”以后，知道了种植马铃薯时，通常是将它的块茎切成几块，每块种薯上要保留一个芽眼，芽眼生出的幼芽生长发育成为一株马铃薯幼苗，没有带芽眼的马铃薯块茎则不能发芽．

为了验证该知识，小杨同学设计进行了下面实验．请根据这一实验分析回答问题．

①两个盛有潮湿的、肥沃土壤的花盆，编号为甲、乙．

②将挑选好的马铃薯块茎切成大小相等的小块若干，分成两组，将有芽眼马铃薯块茎种在甲花盆内，将没有芽眼马铃薯块茎种在乙花盆内．将两花盆放在相同的适宜条件下培养，一段时间后观察．

一根绳子长13米，绕一棵大树10圈后还多出44厘米．这棵大树的直径是多少厘米？

    There is a National Health Service in Britain. People usually call it "the NHS". When people are ill, they can get free treatment（治疗）. ① The government pays for the treatment. In Britain everyone has a local doctor. The local doctor is a general practitioner (全科医生)(GP). A GP is a doctor who treats patients with all kinds of illness. He may not have specialists (专家) usually work in hospitals.

    If a man is ill and wants to see his doctor, he calls to make an appointment first. If he is too ill and he can't go out, his doctor will come to his house. If the patient has to take medicine, the doctor gives him a prescription(处方). ② The patient has to pay some money for the prescription. He goes to the chemist's shop and buys the medicine there. The price is the same as any kind of medicine. ③But children, students, old people or people without work don't have to pay for their medicine
