So it could be put in a tube and then I would be able to suck it more easily. Perhaps I would use a straw to do it. It can prevent the food from floating away.

Only in this way would the problem be solved. I will have a try in time.

品味人生

1、不管鸟的翅膀多么完美，如果不凭借空气，鸟就永远飞不到高空。想象力是翅膀，客观实际是空气，只有两方面紧密结合，才能取得显着成绩。

2、想停下来深情地沉湎一番，怎奈行驶的船却没有铁锚;想回过头去重温旧梦，怎奈身后早已没有了归途。因为时间的钟摆一刻也不曾停顿过，所以生命便赋予我们将在汹涌的大潮之中不停地颠簸。

3、真正痛苦的人，却在笑脸的背后，流着别人无法知道的眼泪，生活中我们笑得比谁都开心，可是当所有的人潮散去的时候，我们比谁都落寂。

4、温暖是飘飘洒洒的春雨;温暖是写在脸上的笑影;温暖是义无反顾的响应;温暖是一丝不苟的配合。

5、幸福，是一种人生的感悟，一种个人的体验。也许，幸福是你风尘仆仆走进家门时亲切的笑脸;也许，幸福是你卧病床上百无聊赖时温馨的问候;也许，幸福是你屡遭挫折心灰意冷时劝慰的话语;也许，幸福是你历经艰辛获得成功时赞赏的掌声。关键的是，你要有一副热爱生活的心肠，要有一个积极奋进的目标，要有一种矢志不渝的追求。这样，你才能感受到幸福。
