    In today's society, everyone is busy and running at a fast pace every day. We feel our time is valuable and needs to be used well. We need cheap meal ideas that can help us save time and money and still provide a healthy and nutritious (有营养的) dinner for us and our family.

    The fast food makers know we have little time and that the idea of cooking dinner after a long day at work is not something we look forward to. So the fast food makers offer us cheap food that requires no cooking, no cleaning, and only 25 minutes to pick up.

    But eating so much fast food will cause body fatness and fast food is not nutritious, so it's not the healthiest choice to consider. There are some very cheap meal ideas that take almost no time to prepare and will make coming home for a good meal more enjoyable.

    The first cheap meal idea is one dish which includes meat, vegetables and rice. This is not only a cheap meal idea, but also it is fast because it can be made in only 20 minutes.

    You can quickly make some pancakes and scrambled eggs for the family in about 30 minutes. If you think it is strange to eat breakfast food for dinner, consider how the same foods give you what you need to go through a whole day.

    Another cheap meal idea to try is a “macaroni and cheese with meat” dish, which only takes around 20 minutes to cook.

    If you are interested in these cheap meal ideas, you’re welcome to visit our website for details. When you fix one of these or other cheap meal ideas at home, you are taking time out of your busy day to treat yourself and your family in a special way.

【研究背景】在畜禽饲料中添加适量的抗生素可减少畜禽机体对抗有害微生物的消耗,降低畜禽机体感染疾病概率,故而被养殖场广泛使用.但是饲料中添加使用抗生素不当会直接危害人体和畜禽的健康.我国科学家耗费多年心血研发的专利“无抗生素微生物发酵饲料技术”,实现了生鸡的全程无抗生素饲养.这项技术被誉为“饲料工业的一场革命”,用这种发酵饲料喂养的鸡被称为“无抗鸡”.

【实验原理】据研究表明,饲料中使用某种特定的芽孢杆菌能促使酵母菌和乳酸菌大量繁殖,占数量优势,同时有效杀死大肠杆菌和沙门氏杆菌等有害菌.随着酵母菌、乳酸菌生长代谢,饲料中一些大分子物质不断被降解,一些小肽、游离氨基酸和维生素数量在不断增加,因而饲料营养价值得到提升.

【实验设计】

实验组别(X)

添加的成分

实验变量(Y)

Y0

Y1  Y2  Y3

对照组(X1)

饲料

无菌水

生产用菌粉



实验组(X2)

饲料

外源芽孢杆菌

生产用菌粉



【实验结果】

(1)在包装好的饲料包中,用酵母菌和乳酸菌混合制成的生产用菌粉中首先增殖的微生物、pH的变化趋势是____ 

A.酵母菌 上升   B.酵母菌  下降       C.乳酸菌 上升   D.乳酸菌  下降

(2)在本实验中,若Y0为实验前各菌种的数量,那么Y1、Y2、Y3表示____ 

(3)根据实验数据分析,本实验证明了____ 

【实验扩展】

(4)若想进一步了解饲喂该发酵饲料与原添加抗生素的饲料对鸡的生长速度的影响,需进一步设计实验验证.请从下列选项中选择合适的项目并按实验的先后排序(可重复)____ .

①生长状况相似的小鸡若干,分组     ②生长状况相似的母鸡若干,分组

③测量各组鸡的平均体重             ④分别饲喂普通饲料和发酵饲料

⑤分别饲喂抗生素饲料和发酵饲料     ⑥分别饲喂普通饲料、抗生素饲料和发酵饲料

⑦在适宜的环境条件下喂养一段时间

(5)青霉素能杀灭细菌的原理是____ .长期使用抗生素会使细菌产生抗药性,原因是____
