    正在松树边闹动争说,只见对面松林里那伙贩枣子的客人,都提着朴刀走出来问道:“你们做甚么闹?”那挑酒的汉子道:“我自挑这酒过冈子村里卖,热了在此歇凉。他众人要问我买些吃,我又不曾卖与他。这个客官道我酒里有甚么蒙汗药。你道好笑么?说出这般话来!”那七个客人说道:“呸!我只道有歹人出来,原来是如此。说一声也不打紧。我们正想酒来解渴,既是他们疑心,且卖一桶与我们吃。”那挑酒的道:“不卖!不卖!”这七个客人道:“你这汉子也不晓事!我们须不曾说你。你左右将到村里去卖,一般还你钱,便卖些与我们,打甚么不紧?看你不道得舍施了茶汤,便又救了我们热渴。”那挑酒的汉子便道:“卖一桶与你不争,只是被他们说的不好。又没碗瓢舀吃。”那七人道:“你这汉子忒认真!便说了一声,打甚么不紧?我们自有椰瓢在这里。”只见两个客人去车子前取出两个椰瓢来,一个捧出一大捧枣子来。七个人立在桶边,开了桶盖,轮替换着舀那酒吃,把枣子过口。无一时,一桶酒都吃尽了。七个客人道:“正不曾问得你多少价钱?”那汉道:“我一了不说价,五贯足钱一桶,十贯一担。”七个客人道:“五贯便依你五贯,只饶我们一瓢吃。”那汉道:“饶不得,做定的价钱!”一个客人把钱还他,一个客人便去揭开桶盖,兜了一瓢,拿上便吃。那汉去夺时,这客人手拿半瓢酒,望松林里便走。那汉赶将去。只见这边一个客人从松林里走将出来,手里拿一个瓢,便来桶里舀了一瓢酒。那汉看见,抢来劈手夺住,望桶里一倾,便盖了桶盖,将瓢望地下一丢,口里说道:“你这客人好不君子相!戴头识脸的,也这般罗唣!”

    For some students, getting better grades can seem like an impossible task sometimes. With the challenges(挑战) of school, just paying attention in class or studying hard isn't always enough. But what if there were other ways for students to improve their grades? For parents and students who have ever wondered if this is possible, now you can rest easy. Research suggests that a person who likes doing activities can improve their grades.

    Scientists think that those students who are active are not just exercising their bodies, but also exercising their brains(大脑). In turn, they can be able to improve their grades at school.

    In the most recent study, researchers found that when children played for half an hour each day, they were better at organizing(组织) their schoolwork as well as doing project work and learning traditionally “difficult” subjects, such as maths.

    What does this mean for children who aren't active? Researchers think that if kids don't get enough activities, they are going to be at a disadvantage when it comes to school performance.

    In the research experiment, a group of children skipped with ropes(跳绳), played basketball and did a number of other games or exercises. Another group of children didn't do any activities. They took part in testing both before experiment and after the experiment. Testing was mainly for maths and reading skills. Results showed that the children in the activity group did better on the tests than those who had no activity.

    All work and no play will not only make Jack a dull(迟钝的) boy, but will also negatively(消极地) affect his grades in school, according to a new study published in the Journal of Pediatrics.

    Parents complain(抱怨) children today are actually less active and they always worry about their grades. Dr. Belton, an expert, said, “If you'd like to see your kids do better in school, have them close their books, set down their pencils and go outside to play.”
