IV Reading(2x10)
Passage one
Questions 1to 5 are bad on the following passage. 1-5 ACBDB
Children are a delight. They are our future. (1)But sadly, hiring someone to take care of them while you go to work is getting more expensive by the year.
Earlier this month, it was reported that the cost of enrolling an infant or small kid at a childcare center ro 3% in 2012, faster than the overall cost of living. There are now large strips of the country where daycare for an infant costs more than a tenth of the average married couple's income.
This is not necessarily a new trend, but it is a somewhat puzzling one. The price of professional childcare has been rising since the 1980s. (2)Yet during that time, pay for professional childcare workers has stood still. Actually caregivers make less today, in real terms, than they did in 1990.steven的圣诞卡 Considering that labor costs are responsibl
e for up to 80% of a daycare center's expens, one would expect flat wages to have meant flat prices.
So who's to blame for higher childcare costs?
Childcare is a carefully regulated industry. States lay down rules about how many children each employee is allowed to watch over, the space care centers need per child, and other minute details. (3)And the stricter the regulations, the higher the costs. If it has to hire a caregiver for every two children, it can't really achieve any economics of scale on labor to save money when other expens go up. (4) In Massachutts, where childcare centers must hire one teacher for every three infants, the price of care averaged more than $16,000 per year. In Mississippi, where centers must hire one teacher for every five infants, the price of care averaged less than $5,000.
Unfortunately, I don't have all the daycare-center regulations handy. But I wouldn't be surprid if as the rules have become more elaborate, prices have rin. The trade off(交换)might be worth it in some cas; after all, the health and safety of children should prob
ably come before cheap rvice. (5)But certainly, it doesn't em to be an accident that some of the cheapest daycare available is in the least regulated South.
