阅读下列材料:

为落实开展社会大课堂活动,七年级(3)班李老师准备周六组织本班学生参观北京科技馆,要求学生周六早9:00准时在科技馆门前集合,然后几种买票参观.

小强家离北京科技馆4公里,周六他准备乘出租车去,为了解北京出租车的计价方式,小强周五晚上在网上查到了现行北京市出租车价格标准:

收费项目

收费标准

3公里以内收费

13元

基本单价

2.3元/公里

低速行驶和等候费

根据乘客要求停车等候或由于道路条件限制,时速低于12公里时,每5分钟早晚高峰期间加收2公里租价(不含空驶费)其他时间段加收1公里租价(不含空驶费)

预约叫车服务费

提前4小时以上预约每次6元,4小时以内预约每次5元

空驶费

单程旅客行驶超过15公里部分,基本单价加收50%的费用,往返载客(即起点和终点在2公里(含)范围以内)不加收空驶费

夜间收费

23:00(含)至次日5:00(不含)运营时,基本单价加收20%的费用

合乘收费

合乘里程部分,按非合乘情况下应付金额的60%付费

燃油附加费

1元/运次

备注:1、早高峰7:00(含)﹣﹣9:00(不含);晚高峰17:00(含)﹣﹣19:00(不含).

      2、出租车计价段里程精确到500米,时间精确到2.5分钟;出租汽车收费结算以元为单位,元以下四舍五入.

      3、过路、过桥费由乘客负担.

      4、按日结算的包车及出北京行政区域的客运业务收费实行市场调节价.

在仔细阅读标准后,小强准备周六早上8点10分乘车,路上留出10分钟出租车时速低于12公里的堵车时间,这样在9点之前一定能顺利到达科技馆.时间设计好后,经过计算小强向妈妈要30元打车钱,妈妈问他30元钱够吗?小强说:“我按上表计算了,30元钱还有几块钱的剩余呢.”

下面是小强的分析与计算过程,请补充完整:

阅读理解

    Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically (心理) and physically.

    Diet products greatly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the amount of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤) instead. All we have to do is to recognize the word “diet” in food labels.

    On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don't have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without struggle.

    The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because eating them instead of healthy foods means we are preventing our bodies from having basic nutrients. Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemicals that go into diet products are possibly dangerous in the future.

    Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
