        那对过众军汉见了,心内痒起来,都待要吃。数中一个看着老都管道:“老爷爷,与我们说一声!那卖枣子的客人买他一桶吃了,我们胡乱也买他这桶吃,润一润喉也好,其实热渴了,没奈何;这里冈子上又没讨水吃处。老爷方便!” 老都管见众军所说,自心里也要吃得些,竟来对杨志说:“那贩枣子客人已买了他一桶吃,只有这一桶,胡乱教他们买吃些避暑气。冈子上端的没处讨水吃。”杨志寻思道:“俺在远远处望这厮们都买他的酒吃了;那桶里当面也见吃了半瓢,想是好的。打了他们半日,胡乱容他买碗吃罢。” 杨志道:“既然老都管说了,教这厮们买吃了,便起身。”众军健听这话,凑了五贯足钱,来买酒吃。那卖酒的汉子道:“不卖了!不卖了!这酒里有蒙汗药在里头!” 众军陪着笑,说道:“大哥,直得便还言语?” 那汉道:“不卖了!休缠!” 这贩枣子的客人劝道:“你这个鸟汉子!他也说得差了,你也忒认真,连累我们也吃你说了几声。须不关他众人之事,胡乱卖与他众人吃些。”   那汉道:“没事讨别人疑心做甚么?”这贩枣子客人把那卖酒的汉子推开一边,只顾将这桶酒提与众军去吃。那军汉开了桶盖,无甚舀吃,陪个小心,问客人借这椰瓢用一用。众客人道:“就送这几个枣子与你们过酒。”众军谢道:“甚么道理!”客人道:“休要相谢。都一般客人。何争在这百十个枣子上?”众军谢了。 先兜两瓢,叫老都管吃一瓢,杨提辖吃一瓢。   杨志那里肯吃。老都管自先吃了一瓢。两个虞候各吃一瓢。众军汉一发上。那桶酒登时吃尽了。杨志见众人吃了无事,自本不吃,一者天气甚么热,二乃口渴难煞,拿起来,只吃了一半,枣子分几个吃了。那卖酒的汉子说道:“这桶酒被那客人饶了一瓢吃了,少了你些酒,我今饶了你众人半贯钱罢。”众军汉凑出钱来还他。那汉子收了钱,挑了空桶,依然唱着山歌,自下冈子去了。

    When the weather is good, most children would like to play outside. So we asked some kids and their parents whether the following toys kept them happy.

All Surface Swingball, $35.99

    Played by Martin, nine, and five-year-old Alex in Crewe, Cheshire.

Mother Jennifer says, “The boys thought the toy was excellent and really wanted to play with it. It can be played with alone or with another child. It's for the right age range but I believe the toy can be played with by all ages and is suitable for the whole family.”
Rubberwood Quoits Set, $13.99

    Played by Jessica, four.

    Mother Lucy Hayburst, 37, in Chichester, West Sussex, says, “Jessica played with this toy for a few minutes but quickly stopped playing with it. Since we bought this toy for her, she only played several times. The quality is very good. It can be played with by one child or more. Besides, I believe it's more suitable for older kids.”

Wooden Animal Skittles, $14.99

    Played by Matthew, two.

    Father Richard Lee, 36, from Dartford, Kent, says, “Matthew was very interested in the toys and liked to play with them, but that only lasted for around five minutes. The skittles were fun at first but that feeling soon disappeared. Two or more children can play with the toy together. And I think they are most suitable for kids aged between three and seven. Our youngest son, Ethan, just kept trying to eat the lion's head.”

First Tailball Net Set, $22

    Played by James, five.

    Mother Sarah Schwar, 39, from Grays, Essex, says, “James loved the toy.” He enjoyed balls so it was perfect for him We used it in the summer as it was easy to take on trips It is suitable for kids over five years old I think the price is fair and your children deserve it.”
