阅读下面短文,根据下面小题的具体要求,尽可能简要回答问题,并将答案转写到答题卡上。

Playing is serious business for children. In fact, it's what they do best! Ask them why they do it, and kids will probably say,"Because it's fun!" But it's much more than that. It's also good for them.

Studies show that from birth babies begin learning through play. They use their five senses to get know their new world. Touching allows them to discover how different things feel. Brightly colored toys and clothing help develop a baby's sense of sight.

When small children choose which toy to play with, they begin developing their abilities in making decisions.

Children love toys that allow them to use their imagination. Sometimes an empty box is more fun than a high-tech toy. That's because a box can become anything a child imagines it to be.

Crayons, paints and Play-Doh(彩色塑泥) are also good because they allow children to create. Traditional building blocks teach important pre-math skills like problem-solving.

Playing doesn't become any less important once children start school. Many valuable lessons about life are learned on the school playground. Kids learn how to share, take turns and play by the rules.

题型:问答题 论述题

A公司中标北方地区某郊野公园施工项目,内容包括绿化栽植、园林给水排水、夜景照明、土方工程、园路及广场铺装,合同期为4月1日~12月31日。A公司项目部拟定施工顺序:土方工程→给排水→园路、广场铺装→绿化栽植→夜景照明。

因拆迁等因素影响,给排水及土方工程完成后,11月才进入园路及广场铺装施工。

园林主干路施工中发生了如下情况:

(1)土质路基含水率较大,项目部在现场掺加石灰进行处理后碾压成形。

(2)为不干扰邻近疗养院,振动压路机作业时取消了振动压实。

(3)基层为级配碎石,现场检查发现骨料最大粒径约50mm;采用沥青乳液下封层养护3d后进入下一道工序施工。

(4)面层施工时天气晴朗,日最高温度为3℃,项目部在没有采取特殊措施的情况下抢工摊铺。

绿化栽植进入冬期。项目部选择天气较好、气温较高时段组织了数十株大雪松和银杏移栽,每株树木用三根直径50mm的竹竿固定支承。在此期间,还进行了铺砌草块施工。翌年4月,路面出现了局部沉陷、裂缝等病害。

指出园路施工存在哪些不妥之处,给出正确做法。
