activities and excursion programme.The International Summer School runs 4 different summer school

centres for boys and girls aged from 7 to 20 in the south of England.

south coast of England-in the much favoured Meads area of the town, within walking distance of the

seafront and town centre.Gatwick Airport is about an hour's drive away and Heathrow around 90

minutes.

     Our 4th School-Bethany Centre-is situated in the heart of Kent-an area known as "The Garden of

England" close to woods and meadows (草地) of the High Weald but only 20 minutes from the town

of Royal  Tunbridge Wells.Gatwick and Heathrow Airports are easily accessible, as are Eurostar

International Stations at Ashford and Ebbsfleet.

    The aim of the International Summer School is to create a lively and happy atmosphere that makes

learning and international communication enjoyable.Young people can thrive, have fun, and gain

considerable skills in English.

     Our programme offers a well balanced timetable of English tuition, sport and fun activities combined

with outings to recreational and cultural centres.A full day in London is always included, as well as other

places of cultural interest.Students of all creeds and cultures are welcomed as our aim is to create a

summer school which can truly be described as "International".

花城市某单位退休干部张三退休后在郊区的老家建了一处宅院，在那里安度晚年。后来张三于 1993年2月病逝，所建宅院由他的三个儿子张四、张五、张六继承。三兄弟在市区住房都很宽裕，就商量把郊区的宅院卖掉。李家兄弟李一和李二愿意购买此房。于是，张家三兄弟与李家两兄弟签订购房合同，约定李家兄弟交付现款2万元。张，李两家在达成协议后到房管部门办理了房屋过户登记手续。因为李家一时凑不出2万元现金，双方又约定两个月后交付。两个月时间到了，李家没有给钱。又过了4个月，张氏兄弟多次催促李一，李一推辞说自己没钱，让张氏兄弟向李二索要房款，并说李二正做生意，手头有现金可付款。于是张家兄弟向李二索款又未果。张四、张五、张六于是分别以李二为被告向同一法院起诉要求还款。法院受理后，认为张氏三兄弟应为共同原告，将三人的起诉合并审理。在审理过程中，因张六出差在外，李二便与张四、张五在法院主持下达成调解协议，由李二支付1．8万元作为购房款给张氏兄弟。调解书送达张六时，张六以当时自己不在场、调解未经其同意为由而拒收，仍坚持要求被告按2万元支付。
