某市孩子的经济成本
孩子的经济成本由孩子出生前和出生后两大费用支出构成。
孩子出生前的有关支出，即从母亲怀孕至孩子出生这段时期与孩子相关的费用估计平均为2771.44元。其中，占孩子出生前费用中，名列前三名的是怀孕期间的营养费(39.69%)、住院接生费(21.41%)和婴儿用品预购费(20.91%)。胎教支出却相当有限，只占3.04%，处于各项支出的倒数第一位。分析结果表明，男孩子的妊娠分娩费用(3313元)要比女孩的费用(2057元)高，高出部分主要体现在额外营养费、雇工照顾费和婴儿用品预购费上的性别差别。生男孩的母亲要比生女孩的母亲多进补331元，高出36.4%；怀女孩的家庭几乎不请人帮忙，比怀男孩的家庭少支付183元的雇工照顾费；男孩的婴儿用品预购费比女孩的高出604元，是女孩的3.6倍。
孩子出生后，抚养其从0～16周岁的费用为119829.30元。食品费用支出最多，为49214.75元；教育费用次之，为17573.21元；然后依次是家庭生活服务费(11981.93元)、衣着费用 (11938.72元)、零花和压岁钱的支出(9336.03元)、文化娱乐活动的支出(7003.12元)、健康保险费(4543.05元)、日用品支出(4341.41元)和医疗保健费(3897.04元)。

     How does a place become a World Heritage Site (世界遗产)? It takes a lot of people to decide.

     1) If a country wants one of its places to be on the World Heritage List, it has to ask JUESCO (联合国教

科文组织).The place must be important and special. UNESCO put the Great Wall on the list in 1987 because it

said it was great part of Chinese culture and beautifully made to go with the land. When a country asks, it must

also make a plan for taking care of the place.

     2) The World Heritage committee of UNESCO talks about different places and decides whether to put them

on the list. The committee meet every June. Many experts help the committee to decide.

     3) After a new place goes on the list, UNESCO gives money to help keep it looking good. If a place is in

serious danger, it may be put on the List of World Heritage Sites in Danger. UNESCO gives special care and

help to those places.

     4) Countries have to give UNESCO regular reports about places on the list. If UNESCO thinks a country

isn't taking good care of a place, the site will be taken off the list.
